Patent JP-H0845961-A (JP)
Title: Field effect transistor
Inventor: MARUHASHI KENICHI
IPC: H01L21/338
Filed: 1994-08-04
Abstract: PURPOSE:To improve a field effect transistor of comb-shaped structure composed of split unit FETs in noise characteristics. CONSTITUTION:Signals inputted through an input line are branched off at an input-side branch point 2 and reach unit FETs 3. Signals amplified through the unit FETs are compounded at an output-side branch point 4 and reach an output line 5. Distances between the input-side branch point 2 and the unit FETs are different, so that signals reaching the unit FETs are different from each other in phase. This means that the unit FETs are different in matching state on an input side. Then, the unit FETs are lessened in gate length with a distance from the input-side branch point 2 so as to keep all the unit FETs good in a matching state. The unit FETs are made to operate in a matching state near to noise matching, whereby a field effect transistor composed of the unit FETs lessened in noise as a whole can be realized.

Title: Inspecting method for electronic parts
Inventor: YOSHIDA ATSUSHI
IPC: G01R31/00
Filed: 1989-07-14
Abstract: PURPOSE:To exactly measure the characteristic of electronic parts by bringing an inspection contact into contact with a terminal while rubbing the contact against the terminal and also allowing a holding plate for obstructing a bend of the terminal by pressing force to abut on the terminal. CONSTITUTION:A switch body 13 is fixed in advance, and moved from the upper part to the lower part in a shape of holding in terminals 11 by inspection contacts 10 at a smaller interval than a pitch between the terminals 11. In the case, between the terminals 11, a holding plate 15 moves downward by synchronizing with the contact, therefore, even if the terminal 11 is pressed to the inside by the contact 10, it is supported by the holding plate 15 and it does not occur that it is bent. Also, the contact 10 comes into contact with the terminal 11, and moves downward along the side face of the terminal 11 by force 16 for pushing it aside to the inside. In the case, the contact 10 breaks and scrapes an oil film and an oxide film 12 adhering to the surface of the terminal 11, by which a state that the contact 10 and the terminal 11 can come into contact directly with each other is obtained.

Title: Production of optical disk substrate
Inventor: NITTA ISAO
IPC: B29C45/26
Filed: 1990-07-10
Abstract: PURPOSE:To smoothly perform degassing for molding to improve the birefringence and the transferability by forming a ruggedness on the outside of an optical disk area on a stamper which forms pits and grooves on the resin material of an optical disk substrate. CONSTITUTION:The gap between a stamper 9 and a stamper retaining ring 10 in a part A is used for escape of air and gas. Since pits and grooves are provided even on the inside of the stamper retaining ring 10, air and gas can be driven out along pits and grooves even if the stamper retaining ring 10 is brought into contact with the stamper 9. Consequently, the resin formed base material is molded in a uniform condition especially in the outer peripheral part because the stamper 9 is freely expanded and contracted. Thus, the birefringence and the transferability in the outer peripheral part are improved, and the resin material is easy to flow in by the existence of pits and grooves.

Title: Home service demand control system
Inventor: MIYAMOTO YOSHIMI
IPC: G01V9/00
Filed: 1992-07-10
Abstract: PURPOSE:To eliminate feelings of inconvenience from ordinary home users by preferentially limiting the operation of equipment in rooms where nobody exists and not limiting as much as possible the operation of equipment in rooms where someone exists. CONSTITUTION:A main controller 14 checks whether or not the total demand current value of a home reported from a demand controller 4 exceeds a prescribed cautious level and, when the value exceeds the cautious level, the controller 14 checks whether or not someone exists in the home based on the information from a human sensor 21 connected to terminal equipment 18a for sensor. When a room is found to be empty, the controller 14 informs each terminal equipment of commands for inhibiting new operation of equipment in such room through home buses 13a-13n. Then the controller 14 checks whether or not the total demand current value exceeds a limit level and, when the value exceeds the limit level, the controller 14 stops the operation of the equipment in the empty room. Therefore, the usefulness of this demand control system is improved.

Filed: 1992-07-10
Abstract: PURPOSE:To quickly detect a specimen DNA or RNA by shortening a DNA or RNA probe in the presence of the specimen DNA or RNA using an enzyme capable of degrading the double-stranded portion of a DNA or RNA from its end.

Title: Cell multiplexing device
Inventor: FUKUDA MASAHIRO
IPC: H04L12/28
Filed: 1994-08-04
Abstract: PURPOSE:To attain a pulling buffer cell multiplexing system including both merits, i.e., the low cost of a conventional input buffer and the low cell canceling rate of an output buffer. CONSTITUTION:A cell processing part judges a required operation mode for an input cell 101 from each of input lines #1 to #N in accordance with a convergence existence/absence signal 106 inputted from a convergence monitoring part, stores a moderate delay quality class in a large capacity pulling buffer by first in first out(FIFO) operation with an input line speed and preferentially outputs a rigid delay quality class as a transmission cell 102. A multiplexed cell obtained by time-dividedly multiplexing transmission cells 102 in respective input lines by a cell multiplexing part is written in a small capacity output buffer part 3 by FIFO operation with N times of the input line speed and read out to an output line as an output cell. When the number of stored cells obtained from the output buffer part exceeds a previously set threshold, the convergence monitoring part judges the existence of a convergent state and informs the convergence existence/absence signal 106.

Title: Semiconductor device and manufacture thereof
Inventor: TANAKA KAZUO
IPC: H01L21/3065
Filed: 1992-07-10
Abstract: PURPOSE:To remove contact failures, leakage current or the like and eliminate any need to increase the width of a poly-silicon layer at a portion of a connection hole. CONSTITUTION:When connecting a semiconductor substrate 100 to a wiring layer, a silicide layer 201 is designed to be present in an opening section 105 even when a silicon layer 103 is deviated from the opening section 105 so that a 10: 1 etching selection ratio may be available between the polysilicon layer 103 and the silicide layer 201, which prevents a silicon substrate in an active area of devices from being etched. As a result, no active area 101 of the devices will be removed by the etching. Furthermore, there is no need to increase the width of the polysilicon layer in the opening section 105. It is, therefore, possible to reduce a chip area by about 30% in the case of a mask ROM of 6 megabits.

Title: Solvent-resistant porous particles
Inventor: AOKI YUTAKA
IPC: B01D15/08
Filed: 1987-07-23
Abstract: PURPOSE:To improve solvent-and alkalinity-resistance by molding solvent- resistant porous particles using a cross-linking copolymer of noncross-linking monomer and cross-linking monomer as raw material and limiting the grain diameter of the particles to 5-300mum. CONSTITUTION:Solvent-resistant porous particles with a grain diameter of 5-300mum are formed using a cross-linking copolymer formed of noncross-linking monomer and a cross-linking monomer. As for the above-mentioned cross-linking copolymer, one containing 10-90wt.% of cross-linking monomer is favorable, and having a hydrophobic noncross-linking monomer as a component is also favorable. The porous particles obtained are highly solvent- and alkalinity- resistant, and besides, their compatibility with the characteristics of a sample can be improved by controlling the physical properties and porosity of the particles. Consequently, the sample having pretreating accuracy is obtained and therefore, liquid chromatography can be performed with superior precision and high efficiency.
