Invited paper to the Sixth International Quantum Electronics Conference, Kyoto, Japan, September 1970. T. Kobayasi and H. Inaba. Proceedings of IEEE., 58, 1568, (1970).""Author Institution: Research Institute of Electrical Communication, Tohoku UniversityThe usefulness of Raman spectroscopy, which is so far recognized as a complementary technique to infrared spectroscopy, can be extended to include various new fields which are unique to itself. The laser-Raman radar scheme detecting the Raman backscattered echoes has been and confirmed experimentally by the present , which is capable of measuring remotely the number density of molecular constituents as well as their species existing not only in the ordinary but also in the polluted atmosphere. This paper wishes to report the operational performance and the experimental results, so far obtained, of our laser-Raman radar as a completely single-ended system for the chemical analysis of the real atmosphere. An alternative method, which utilizes a frequency-tunable dye laser with high repetition rate of pulsed operation is also developed to investigate the resonance spectroscopic effects of a variety of molecules and atoms contained in the lower and upper atmosphere. These effects include the fluorescence and the resonance scatterings along with the resonance Raman scattering, and are expected to improve significantly the sensitivity and the range capability for the constituent analysis of our environmental air

This paper presents the measured result and their comparison of the Raman cross sections of various molecules present in the atmosphere such as relative to that of as a reference gas. We employed primarily a molecular nitrogen laser with 10mW average power at 3371 {\AA}, 20 kW peak power of 10 nsec duration and a repetition rate of 50 Hz. Recently, we have succeeded in the operation of transverse excitation atmospheric (TEA) nitrogen laser at 3371 {\AA} which is applicable to the field-use and also to the laboratory experiments. The Raman scattered radiation was observed in a direction perpendicular to the linearly polarized plane of the incident laser beam. The signal was processed by the pulse-gated photon counting method synchronized with the repetitive laser pulse, which is valuable for detecting extremely weak light signals. The accuracy of our measured cross sections is within 10\% and their values were found to agree well with the pre-laser result by Murphy et and the laser result by Fouche et for several gases. It is noteworthy that band has 15 times and band has 7.2 times larger cross section than that of , due possibly to resonance Raman effect at 3371 {\AA}
Small angle neutron scattering studies of magnetic recording media
No full textIn the beginning of the twenty-first century, educational and commercial institutions have driven the demand for cheap and efficient data storage. The storage medium known as magnetic recording media has remained the mainstay for most computer systems due to its large storage capacity per dollar. With the recording media's ever-increasing storage density has come reductions in the magnetic grain size per bit. At the recording bit's density threshold, the magnetic grains become more susceptible to thermal activation, which can render the storage medium unusable. An accurate characterisation of the recording layer's sub-granular structure is essential for understanding the magnetic and thermal mechanisms of high-density recording media. Small-Angle Neutron Scattering (SANS) studies have been performed to investigate the magnetic and physical properties of longitudinal and perpendicular recording grains.
The SANS studies of longitudinal magnetic recording media have probed the recording layer's magnetic grain size at a sub-nanometer resolution. In conjunction with these studies, SQUID magnetometry was used to characterise the recording grain's bulk magnetism. Measurements showed that the recording grain was composed of a ferromagnetic hard core (Co-enriched) and a weakly magnetic shell (Cr-enriched). These results provided important information on the grain's magnetic anisotropy, which determines the recording media's magnetic stability. The polarised SANS studies were used to characterise the recording layer's physical granular structure. It was shown that the physical grain size was comparable to its magnetic counterpart. These physical measurements provided insight into the recording grain's chemical composition.
The magnetic properties of perpendicular magnetic recording media were studied using SANS and VSM measurements. The neutron scattering studies revealed that the recording grain was composed of a hard ferromagnetic centre enriched with cobalt. The VSM studies showed that the magnetic recording grains exhibited a large perpendicular magnetic anisotropy. These combined studies provided information on the recording grain's ferromagnetic composition and magnetic stability. The polarised SANS measurements showed the physical grain size to be slightly smaller than its magnetic counterpart. This size difference was attributed to the non-magnetic grain boundary composed of SiO2. The boundary thickness determined the degree of inter-granular exchange coupling. Further polarised studies investigated the recording layers switching behaviour, which revealed more information on the grain's magnetic stability
Ethics for Humanity That May Not Perish
No full textThis work is an English translation of the book “Metsubousurukamosirenai Junrui no tameno Rinrigaku[Ethics for Humanity That May Perish: LongTermism, Transhumanism, and Space Exploration]” by author, Shin-ichiro Inaba, himself. The original Japanese version was written for introducing Longtermism, Existential Risk Theory and related topics to Japanese general readrers. Chapters One and Two trace the origins of longtermism as a theoretical framework and philosophy. Chapter 3 briefly summarizes the theoretical core of what longtermism is and introduces accelerationism and effective accelerationism as adjacent movements that also concern humanity in the super-future. Chapter 4 points out that animal ethics can become a stumbling block for longtermism—giving rise to a peculiar puzzle. Chapters Five and Six examine the difficult problems in intergenerational ethics raised by Parfit, keeping the context of longtermism in mind. Chapter Five focuses on the "repugnant conclusion," while Chapter Six centers on the "non-identity problem." Chapter 7 points out that the "Singleton", according to Bostrom, deemed essential for humanity to survive and develop long-term by overcoming "existential risks," could itself be a source of such risks. Chapter 8 introduces the "Fermi Paradox" – the puzzle of why, despite the vast number of celestial bodies in the universe, extraterrestrial intelligence (ETI) remains undiscovered – and demonstrates its deep structural and substantive connection to the theory of existential risks. Chapters 9 and 10 discuss the possibility and desirability of humanity's space exploration. In closing this book, we will briefly touch upon the "eschatological" aspects of these arguments

No full textReview Of Japanese Homes And Lifestyles: An Illustrated Journey Through History By K. Inaba And S. Nakayama, Translated By J. Bester
No full textInaba\u27s slight but costly volume, originally published in Japanese in 1983, is noteworthy for Nakayama\u27s illustrations. Modeled after David Macaulay\u27s series (Cathedral, Pyramid, City), they are exquisitely drawn albeit inevitably fanciful in certain details. But the text is academic and puerile; it reads like a middle school textbook. It assumes a rudimentary knowledge of Japanese history, not expected of the average reader of the translation, and yet, in discussing architecture, it is flatly descriptive with hardly any attempt at critical interpretation. The discussion is chronological but not historical; it lacks a large historical sense of connections and continuities. The author\u27s slant is folk architecture and the text thus slights the dwellings of the nobility and the ruling class--the shinden and the shoin--that have traditionally been overemphasized at the expense of farm houses and townhouses. The fruitful cross-fertilization of the urban and the rural, if that was the author\u27s interest, is not adequately articulated. No footnotes, no bibliography. Not for academic audiences
