Title: Oxide superconducting composite wire material
Inventor: TANAKA YASUZO
IPC: C01G1/00
Filed: 1992-09-01
Abstract: PURPOSE:To provide an oxide superconducting composite wire material having enhanced mechanical strength and current density, and ensuring high complex workability at the time of manufacture. CONSTITUTION:Regarding an oxide superconducting composite wire material comprising at least silver and silver alloy compounded with an oxide superconductor, the total amount of the silver and silver alloy is decided on the basis of a space factor within a range satisfying a relationship expressed as 0.9>Aa+1.18Aac (Aacnot equal to 0)>0.5, where Aa is a silver space factor, Aac is a silver alloy space factor, and As+Aa+Aac=1, provided that As is the space factor of the oxide superconductor. Furthermore, in this oxide superconducting complex wire material, the space factors of the silver and silver alloy are determined so as to fall within the predetermined range for causing the silver alloy to act as a reinforcement. Thus, complex workability is remarkably improved at the time of manufacturing a wire. Also, as a ratio of silver to an oxide superconductor is small, the conductor current density of a wire material is substantially improved. The strain resistant characteristic of the oxide superconducting wire material is also improved. Furthermore, a practical effect becomes extremely high, including the easy application of a multi-conductor design to the oxide superconductor.

IPC: F27B1/16
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent the float-up and the break-down of a tuyere brick caused by vibration at the time of fitting a plug by forming the tuyere brick over to the whole length in the range from the working surface contacting with molten metal to the surface contacting with an iron shell and arranging a projecting part in the end part at the iron shell side. SOLUTION: The tuyere brick 10 is integrally formed over to the whole length in the range from the working surface 11 contacting with the molten metal to the surface contacting with the iron shell 5, and the projecting part 10a projected on the outer periphery, is formed in the end part at the iron shell 5 side. Since the tuyere brick 10 is bit into a permanent brick 4 with the projecting part 10a of the end part at the iron shell 5 side, the float-up caused by shock at the time of punch-fitting the plug 6, is restrained and the free vibration is restrained too and the damage of the break-down, etc., can be prevented. Therefore, the changing work of the plug 6 in the hot-state is smoothly executed.  Since the vibration of the tuyere brick 10 is restrained, the gap between the tuyere brick 10 and a work brick 3 and the permanent brick 4 contacting with the outer periphery of the tuyere brick, is difficult to develop and it can be prevented that the molten steel in a vessel reaches the iron shell 5.

Title: Cad system
Inventor: INOUE KAZUO
IPC: G06F17/50
Filed: 1986-10-31
Abstract: PURPOSE:To shorten the time required for design route check DRC by subjecting only a wiring pattern to DRC if this wiring pattern is corrected. CONSTITUTION:A DRC module 4 checks whether intervals of respective wiring patterns are proper or not. If the interval of a certain wiring pattern is improper, an error flag 5c is set. When an operator corrects this wiring pattern, a correction flag 5b is set. The DRC module 4 checks again whether the interval of the wiring pattern where the correction flag 5b is set is proper or not. Since only the wiring pattern is subjected to DRC if error exists in pattern information corresponding to this wiring pattern and this wiring pattern is corrected, the time required for DRC is considerably shortened.

Title: Wire saw and work cutting method using wire saw
Inventor: FURUNO TOMOSUKE
IPC: B24B27/06
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent various malfunction caused by run-out of abrasive grains by constantly supplying a sufficient abrasive liquid between a wire and a work at its cut part to prevent the run-out of the abrasive grain in the work cutting. SOLUTION: An ingot I is relatively pressed against a traveling wire 11a (wire row 11) while supplying a free abrasive grain-containing abrasive liquid. Its grinding action cuts the ingot I. Where, wire vibration means 18 forcibly vibrates contact parts with the ingot-connecting part of the traveling wire 11a with the aid of the projection 16a of a cam roller 16 rotated by means of an electric motor 17. The result makes a gap between the wire 11a and the ingot I at its cut part for every vibration. Flowing the abrasive liquid into the gap replenishes the free abrasive grain.
