Patent JP-S63102269-A (JP)
Title: Superconducting transistor
Inventor: SASA MASAHIKO
IPC: H01L29/43
Filed: 1986-10-20
Abstract: PURPOSE:To approach a superconductor to a twodimensional gas layer thereby to be able to sufficiently utilize the oozing effect of superconducting electrons by using a transistor which becomes a base as an inverted HEMT and employing series including In as a compound semiconductor. CONSTITUTION:A carrier supply layer 4 (e.g., In0.52Al0.48As electron supply layer) 4 made of In-containing compound semiconductor, and a two-dimensional carrier gas layer 12 made similarly of the In-containing compound semiconductor are sequentially formed on an Inp substrate 1. An In0.53Ga0.47As channel layer 6, an InGaAs graded layer 7 made similarly of the In-containing compound semiconductor, a pair of ohmic electrodes (e.g., a source electrode 9 and a drain electrode 10) formed on the layer 7 and made of superconductors, and a gate electrode 11 formed between the pair of ohmic electrodes for controlling the layer 12 are formed. Thus, since the extension of a surface depletion layer is small even if the metal electrodes are contacted in this manner, it can be reduced in thickness. Accordingly, the superconductors can be approached to the two-dimensional carrier gas layer, and the oozing effect of the superconductive electrons can be sufficiently utilized.

Title: Stator core for electric machine
Inventor: FUJISAWA TOMOYUKI
IPC: H02K9/08
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To obtain a stator core for an electric machine whose cooling effect by a refrigerant gas has been improved. SOLUTION: A stator core 1 uses ventilating ducts formed by using mainly duct pieces 2 which are formed by arranging duct piece segments 3 in a zigzag manner compared with a conventional art. The duct piece segments 3 made of a thin steel plate material is formed into a strip of a flat plate having the same width with an interval (d), and fixed to iron cores 42 arranged in such a way as to face the ventilating ducts by welding. As a result, the duct piece segments 3 have the longitudinal dimension almost equivalent to the one obtained by dividing into three the linear distance (L) from the inlet part up to outlet part of a refrigerant gas in the ventilating ducts.

Title: Coin-shaped nonaqueous electrolyte secondary battery
Inventor: TSUCHIYA KENJI
IPC: H01M10/058
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To avoid the internal short-circuit in assembling and over discharge by specifying the thickness ratio of a positive electrode pellet to a sealed vessel in a coin-shaped nonaqueous electrolyte secondary battery. SOLUTION: In a coin-shaped nonaqueous electrolyte secondary battery, a nonaqueous electrolyte is housed in a sealed vessel formed of a positive electrode can 1 and a negative electrode can 7. In such a secondary battery, the thickness ratio of a positive electrode pellet 2 to the sealed vessel is set to 0.3-0.5. When the thickness ratio is less than 0.5, the height of the cylindrical part of the separator 3 is relatively reduced, and the internal short-circuit resulted from the unevenness in height of the cylindrical part is made difficult to avoid. On the other hand, when the thickness ratio exceeds 0.5, the capacity of a negative electrode pellet 5 is reduced to reduce the discharge capacity of the secondary battery. The more preferable thickness ratio of the positive electrode pellet 2 to the sealed vessel is 0.32-0.40. The reliability of the battery is thus improved.

Title: Method and device for arranging graphic
Inventor: UHARA HISAYOSHI
IPC: G06T11/80
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To arrange a graphic so that a relative position with the graphic becoming a reference is automatically kept by setting one arbitrary point that a user selects as a reference point and arranging a low-order graphic subordinated to the graphic becoming the reference. SOLUTION: Distance quantities (X and Y) from the coordinate of a reference point 36 selected from a control box 34 to the coordinate of the generation original 30 of a subordinate low-order graphic 32 decides a relative position between the subordinate high-order graphic 31 and the subordinate low-order graphic 32. When the coordinate of the reference point 36 of the subordinate high-order graphic 31 moves the subordinate low-order graphic 32 can automatically be moved so that the generation original 39 of the subordinate low-order graphic 32 is arranged in a position equivalent to the distance quantities (X and Y) from the coordinate of the moved reference point 38 by changing the size of the subordinate high-order graphic 31.  Since one point becoming the reference for constituting a subordinate relation can arbitrarily-y be selected from plural points containing the generation original on the graphic becoming the reference, user work can be saved at the time of compiling the graphic.
