Fabrication of 1 T Bi-2223 Superconducting Magnet with 92 mm Bore Diameter at 77 K
Get PDFProceedings of the Cryogenic Engineering Conference (2013) , June 17–21, 2013, Anchorage, Alaska, USAA Bi-2223 superconducting magnet for practical use in liquid nitrogen is designed and fabricated. Bi-2223 tapes
prepared by ConTrolled Over Pressure (CT-OP) process are used for the winding, and the critical current at 77.3 K and self-
field is in the range of 174–185 A. 28 double-pancake coils are resistively connected in series by copper terminals. High
critical current tape is used for top and bottom double-pancake coils, since the magnetic field normal to the tape surface is
highest at the top and bottom of the magnet. Two iron plates at top and bottom of the magnet are used for reduction of the
normal component of magnetic field to the Bi-2223 tape, since the total performance of the magnet is determined by the
minimum critical current at maximum normal magnetic field component to the tape. The inner bore diameter of the magnet
is 92 mm. And the homogeneity of magnetic field of long-axis direction in 50 mmφ × 100 mm length is within 3%. The
maximum magnetic field at the center of the bore is over 1.0 T at 77.3 K
Efficient production of bisphenol-A by utilizing cation-exchange polystyrene resins that are cross-linked by naphthalene or a biphenyl unit
Get PDFIon-exchange materials are well known for their utilization in the processes of water treatment,1, 2, 3, 4, 5 demineralization,6, 7 water softening,8, 9, 10 ultra purification of water11, 12 and removal of unwanted ions,13, 14 as well as in chemical processing.15 One ion-exchange material is acidic sulfonated polystyrene-divinylbenzene (DVB) cation-exchange resin, which has an important role in the production of bisphenol-A by participating in an acid-catalyzed condensation reaction between phenol and acetone. Bisphenol-A is a very important raw material for the synthesis of epoxy resins and polycarbonates; thus, >400 000 tons of bisphenol-A have recently been domestically produced
A Text Selection Technique using Word Snapping
Get PDFKES-2014 18th International Conference on Knowledge-Based and Intelligent Information & Engineering Systems, September 15-17, 2014, Gdynia, PolandConventional copy-and-paste technique for touch screen devices utilizes region handles to specify text snippet. The region handles appear so as to select the initially tapped word, and the user controls the region handles. Most of the text-selection task is performed at the boundary of words, however, the minimum movement unit of the region handle is still a character. We propose a context- sensitive text-selection method for the tablet OSs. For the initial consideration, we investigated a word-snapping method that meant a word as a minimum movement unit. From our experiment, we confirmed that the word-snapping method can significantly reduce the text-selection time if the target text consists of one or two words, and no line breaks exist
