    AbstractIn this work, the existing Higuchi models were used for the prediction of gas permeability through the nanocomposite membranes. Predicted values were compared with experimental results of permeability for polycarbonate/silica nanocomposite membranes. Based on the critical analysis of the models predictions and its deviations, the parameter that influences the permeation behavior has been identified. The results revealed that for any particular gas, the change of empirical Higuchi parameter exhibited a direct impact on the accuracy the model. Thus, a modified parameter was incorporated on the modified Higuchi model relating to the intrinsic properties of the penetrant gas. With the new proposed Higuchi model, appreciable predictions of gas permeability through polycarbonate/silica nanocomposite membranes were achieved. The calculated absolute average relative error for CO2, N2 and CH4 gas permeability were found to be 7.18%, 6.07%, and 6.14%, respectively. Their corresponding standard deviations were obtained as 2.53, 1.53 and 0.73 Comparing the existing Higuchi models predictions, the new proposed Higuchi model has resulted to a reduction in relative errors by 6.3% for CO2, 70.66% for N2, and 65.25% for CH4

    In darkness and seclusion : rhetoric of madness and problems of modernity in the works of Higuchi Ichiyō (1872-1896)

    No full text
    The author attempts to analyse how madness is aestheticized and poeticized in the late novellas by Higuchi Ichiyō (1872-1896). While referring to the concept of illness as a metaphor as developed by Susan Sontag and applied to the Japanese context by Karatani Kōjin, the author elaborates on the evocative and symbolic images of madness in Ichiyō’s works. The possible correspondences between the analyzed metaphors and the discourse of modernity in Meiji Japan are also considered Higuchi

    Caught in between : women of the demimonde in Higuchi Ichiyō’s narratives

    No full text
    The article focuses on “Nigorie” (Muddy Bay, 1895) and “Takekurabe” (Comparing of Heights, 1895(1896), two stories for which Higuchi Ichiyō (1872(1896) used the demimonde as a setting. “Nigorie” is staged at Kikunoi, an unlicensed house of pleasures, “Takekurabe” – at Daionji (mae, in the vicinity of the famous Yoshiwara district. The author of the article starts with elucidating the cultural role of the red (light and its impact on Japanese literature. Then she proceeds to illustrate how Higuchi Ichiyō, while referring to the rich tradition of literary motifs and symbols, managed to use them creatively and adjust them to the circumstances of early(modern Japan. The author uses the examples of kaimami (erotic gazing), shinjū (double suicide) and shusse (social promotion) and juxtaposes their traditional meaning with their significance in the context of Ichiyō’s stories. The debate regarding Ichiyō’s approach to her literary and cultural heritage is followed by the close(reading of the two texts. The first goal here is to reconstruct Kikunoi and Daionji(mae as presented in Ichiyō’s works. A comparative method enables the author to highlight the similarities (use of deception, commercialisation, reification) and differences (juxtaposition of prestige and coarseness). Finally, Oriki and Midori, the protagonists of the stories, are considered. The author distinguishes juxtaposition and symbolic use of images as two main methods of rendering the psychology of Ichiyō’s heroines. Their psychological complexities, aggravated by the special status of the pleasure quarters, may be interpreted in the framework of the “caught in between” metaphor

    Contact-free handling using actively controlled electrostatic levitating fields

    No full text
    In general electric field forces have the distinctive property of being able to mediate forces to virtually any material in a fully non-invasive and contact-free fashion. Based on this property, electrostatic levitation holds great promise for the semiconductor, solar panel, and flat-panel display industry since the handling of (semi)conducting and dielectric materials in a contact-free manner can bring many advantages and solve long-standing contamination and particulate control problems. These problems arise from the direct mechanical contact through which dielectric and semiconductor materials are commonly handled by process equipment in these industrial areas. Direct mechanical contact can cause chemical and particulate contamination of the handled material. Furthermore, it can result in electrostatic charging through tribo-electric effects, which raises the electrostatic potential of the handled material causing air-borne particles to be attracted to it. Ultimately, chemical and particulate contamination can critically affect performance, reliability, and product yield of the manufactured devices. Electrostatic levitation offers the inherent capability to avoid these contamination problems. In addition to enhancing contamination control, electrostatic levitation can provide uniformly distributed suspension forces. This is an advantage in the handling of very large and thin glass substrates used in the manufacture of flat panel displays as it leads to minimal mechanical deformation of the substrates. This thesis presents a comprehensive and in-depth study on the use of electrostatic fields for the contact-free suspension of (semi)conducting and dielectric materials. The electrostatic levitation devices that have been developed are specifically geared toward novel applications in the semiconductor and flat-panel display industry. Closed-loop feedback control is necessary to stabilize the position and attitude of the levitated object. In order to stably levitate an object, only three degrees of freedom are required to be actively controlled, i.e. the vertical motion and the angular motions represented by the pitch and roll angles. The lateral and longitudinal movements are passively stabilized by restrictive forces originating from the fringing fields existing between the outer edges of the stator electrodes and the suspended object. A generic voltage-controlled electrostatic levitator for the contact-free suspension of conducting disks or panels was developed first. Its main building blocks consist of a feedback controller, high-voltage dc amplifiers, displacement sensors, and a stator electrode structure. Simple guidelines based on the assumption of uniform electric fields are established for the design of suitable stator electrode patterns and applied voltage distributions, which guarantee electric potentials on disks/panels close to zero volts. Squeeze film air damping plays a major role since it may impact the dynamic behavior of the levitator significantly. The reason for this lies in the fact that the forces arising from squeeze film damping can approach values that are of the same order of magnitude as the electrostatic suspension forces. We also investigated both theoretically and experimentally the restrictive lateral forces produced by the fringing fields. These forces are weaker than the levitation forces. In line with the theoretical model, the measurements show that the lateral force can be increased by applying higher stator voltage magnitudes or by decreasing the air gap separation. Based on these observations, the stator design was improved by adding a ring of peripheral sector electrodes having the primary function of generating the fringing fields. Levitation experiments have been conducted in an atmospheric environment, demonstrating the successful suspension of a 4-inch silicon wafer, having a mass of 9.4 g, at a nominal gap separation of 300 µm utilizing centralized PID feedback control. At constant ring electrode voltages of ±1.2 kV, a lateral stiffness value of 0.84 N/m was produced by the improved stator produced, which corresponds to an increase of a factor of 5.5 relative to the conventional stator. A major and growing industrial area of potential application of electrostatic levitation constitutes liquid crystal display (LCD) manufacturing. Glass substrates are basic and essential components in LCDs. They belong to the class of lossy dielectrics. Their charge relaxation times may complicate the task of levitating them stably. A stator electrode suitable for the levitation of lossy dielectrics consists of a regular planar array of parallel bar electrodes to which voltages of differing polarities are alternatingly applied. We develop a general analytical model of the levitation field and force on a lossy dielectric plate produced by this stator electrode. This model takes into account the influence of the atmospheric humidity on the electrostatic charging dynamics. The levitation force dynamics are studied by evaluating the transient response of the field under a step in the applied voltages. In this context, the rate of electric charge build up on the plate is characterized by the suspension initiation time (TSI), which is defined as the time elapsed between applying step voltages to the stator electrodes and start of lift-off of the dielectric plate from its initial position. TSI is theoretically predicted for 0.7 mm thick soda-lime glass substrates, typically used in the manufacturing of liquid crystal displays (LCDs), as a function of electrode geometry, air gap separation, ambient humidity, and step voltage magnitudes. The predicted results are shown to be in good agreement with previously published experimental data. Position measurement based on capacitive sensing technology has been investigated as well since it can lead to an improved level of levitator cleanliness. This stems from the fact that the sensing electrodes can be integrated into the stator electrodes rendering compact, planar structures. A charge-discharge capacitive displacement sensor with improved stray capacitance immunization capabilities was developed. In addition a simple and cost-effective capacitive sensor using the oscillation principle was designed and realized. Both sensors have been calibrated for different target materials, i.e. silicon, aluminum, and soda-lime and quartz glass. Measurements demonstrate a good linear behavior for both sensors. The final part of this thesis deals with cost-effective and compact electrostatic levitator designs. These designs are characterized by small footprints to ensure cleanliness and scalable to many degrees of freedom multi-electrode levitators without incurring excessive and prohibitive economic costs. The first designed levitator is driven by a relay based switching controller. Its key properties are that it is devoid of high-voltage dc amplifiers and a maximum number of only two high-voltage power supplies, capable of delivering constant dc voltages, are required. This number is entirely independent of the number of individually controlled stator electrodes. The inherent switching nature of the system imposes limit cycle oscillations on the levitated object. It is due to the squeeze-film air damping that these oscillations can be significantly suppressed, in particular at small gap separations down to 100 µm or lower. Successful levitation has been achieved for 4-inch silicon wafers, 100×100 mm quartz glass substrates, and a highly flexible aluminum sheet measuring 280×280 mm, respectively. Experiments with the silicon wafer and glass substrates at reference air gap separations down to 100 µm or lower demonstrate limit cycle amplitudes below 1 µm. The second levitator is based on hysteresis control and represents a fundamental improvement on the first levitator in that it enables incorporating active damping in the system through derivative control. This fact opens up the possibility of operating the levitator in vacuum without degradation in performance as demonstrated by simulations. Overall, the proposed levitator retains largely the advantages of the relay control driven levitator. A 4-inch silicon wafer was levitated successfully at a reference gap separation of 200 µm exhibiting a good transient and steady-state suspension performance. The measured switching period was 1.5 ms and the amplitude of the voltage ripple was 10 V. The stability of the limit cycles in both levitators has been analyzed using the describing function method and Filippov’s theory. The first method follows an approximate approach while the second method offers a more precise avenue of tackling the stability analysis coupled with the key capability of analyzing multi-DOF systems.Precision and Microsystems EngineeringMechanical, Maritime and Materials Engineerin
