Title: Semiconductor device
Inventor: IWASAKI MASAMI
IPC: H01L21/331
Filed: 1985-06-20
Abstract: PURPOSE:To improve the load short-circuiting withstand strength of a large power transistor by increasing the opposing length of a base electrode lead with an emitter electrode, and increasing an initial ON region. CONSTITUTION:Leads B of a base electrode of a transistor are disposed on both sides of a pattern, and the opposing length with an emitter electrode (the rear stage emitter electrode in case of a Darlington transistor) is increased. In comparison with the case that a lead E of the emitter electrode is one, the two or more leads B of the base electrode are provided from the periphery of the emitter electrode. The opposing lengths 41, 42 with the emitter electrode of the leads of the base electrode are increased to increase the initial ON region, thereby improving a load short-circuiting withstand.

Title: Character string group retrieval device
Inventor: TAKEUCHI KOJI
IPC: G06F17/30
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To search plural retrieval character strings existing at the designated positions covering the adjacent record lines by finding a necessary retrieval character string at the same position of the adjacent record lines and specifying a list analyzing place. SOLUTION: A control part 7 takes the retrieval character strings one by one out of a retrieval character string group storage part 3 and instructs a character string retrieval part 4 to search a text and to find an area that is coincident with the retrieval character string. When the retrieval is carried out at the first retrieval character string of the part 3, the part 7 also instructs the part 4 to successively search the record lines of the text stored in a text storage part 5 at and after the head record line. When the retrieval is carried out at the second retrieval character string and the text of the part 5 already includes an area coincident with the first retrieval character string, the part 7 instructs the part 4 to search the second retrieval character string right after the digit position of the coincident area.  The part 4 searches the record line of the text of the part 5 for the retrieval character string instructed by the part 7 and notifies the part 7 of both record line and digit positions of the coincident character string area.

Title: Ic tester
Inventor: MURATA MICHIO
IPC: G01R31/319
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To judge a high impedance from stored data, by comparing whether an output of an object to be tested (DUT) is higher or lower than a comparison voltage of a high level and a low level at a window partition, and storing comparison results. SOLUTION: A DUT output is compared with a high-level comparison voltage and a low-level comparison voltage by comparators 11 and 12, respectively. A memory circuit 30 comprising AND circuits 21-24 and DEF 31-34 receives comparison results from the comparators 11, 12, and stores data of whether the DUT output is always higher than the high-level comparison voltage and always lower than the low-level comparison voltage at a window partition. Moreover, the memory circuit stores data of whether the DUT output is always lower than the high-level comparison voltage and always higher than the low- level comparison voltage. A digital comparator 40 compares the signals with an expected value, and outputs a status and a pass/fail. A high impedance can be detected in this manner.

Title: Method for preventing oxidation of structure in reactor vessel of gas-cooled reactor
Inventor: SHIBATA DAIJU
IPC: G21D1/00
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To prevent oxidation of structure in a reactor vessel by consuming oxygen included in coolant by reacting oxygen with a specific structure and/or an element other than oxygen by using a photocatalyst activated by a γ ray. SOLUTION: A photocatalyst (titanium oxide or the like) 3 is installed on the inner surface of a coolant passage hole 2 formed in a hexagonal prism- shaped graphite structure 1. Reactivity of the photocatalyst 3 is activated by a γ ray in a reactor vessel. When coolant 4 flows into the coolant passage hole 2, oxygen included in the coolant 4 as an impurity is brought into contact with the photocatalyst 3 to activate its reactivity, and reacts with the graphite structure 1 adjacent to the photocatalyst 3 to produce carbon oxides. As a result, a coolant 5 in which oxygen is consumed flows out of the outlet of the coolant passage hole 2, to prevent oxidation of other structures comprising graphite or the like.  When elements other than oxygen are included in the coolant 4, oxygen having activated reactivity is consumed by reaction with the elements to obtain the coolant in which oxygen is removed.

Title: Electrostrictive printing head
Inventor: TANOSHIMA KATSUHIDE
IPC: B41J2/295
Filed: 1981-09-01
Abstract: PURPOSE:To hasten the speed of printing by a method in which an electrostrictive element is fixed to a flexible plate, a printing wire is fixed to the free end of the plate, and printing is made by deforming the electrostrictive plate. CONSTITUTION:A printing wire 2 is fixed to the free end of an electrostrictive plate 1 attached with a stainless steel plate. When applying a high voltage of about 500V to the plate 1, the plate 1 is deformed, and the printing wire is displaced and projected from a wire guide 5 collide against a recording medium. When the high voltage is removed, the electrostrictive plate 1 is restored to its original state. In this case, since its contact point with a stopper 6 is moved from the fixed end of the plate 1 to the free end, vibration generated in the plate 1 is quickly damped when the plate collides against the stopper 6. Thus, the speed of printing can be hastened.

Title: Vane compressor
Inventor: NAKAYAMA SHIYOUZOU
IPC: F04C18/344
Filed: 1981-08-31
Abstract: PURPOSE:To prevent abnormal rise of pressure due to compression of liquid and to thereby protect vanes of a vane compressor against damage, by shaping the inner wall surface of a cylinder in a form satisfying a particular relationship, and selecting the inner diameter of the cylinder to be 0.02-1mm. greater than the minimum length of the vanes. CONSTITUTION:A cylinder 10 is not shaped in a perfectly circular form but shaped in a form satisfying a particular relationship. That is, in a section B shown in the drawing, a tip seal 72 is urged outward from its slot 68 along with rotation of a vane 62 and kept in contact with the inner wall surface of the cylinder 10. Therefore, when pressure in a compression chamber 74 is raised to a level overcoming the above urging force, the tip seal 72 is forced back into the slot 68 by the pressure in the compression chamber 74 and a predetermined clearance (0.02-1mm.) is formed between the tip seal 72 and the inner wall surface of the cylinder 10. Resultantly, the high pressure developed in the compression chamber 74 is released through the clearance into a compression chamber 76 preceding the vane 62 and then into a discharge chamber 22, so that it is enabled to prevent abnormal pressure rise in the compression chamber.
