Title: Three-layered bimetal
Inventor: MORI FUMIO
IPC: B32B15/20
Filed: 1978-04-10
Abstract: PURPOSE:To develop a thermostat usable at high temperatures by interposing an intermediate layer which is excellent in conductivity, heat resistance, and mechanical strength between the high expansion and low expansion metals of bimetal. CONSTITUTION:An intermediate layer of a low resistance and a high conductivity is interposed between the high expansion metal and the low expansion metal of a bimetal. The Cu-alloy as the intermediate layer contains 0.5 to 1.5% Cr, 0.15 to 0.5% Zr, 0.005 to 0.10% each or a mixture of Si, Mg, Ge, and B. The greater majority of the ocmposition of the bimetal is Cu which is of a high conductivity, and also its heat resistance is increased by the interaction of Cr and Zr. And, the inclusion of Si, Mg, Ge, and B, dispersing into the Cu-alloy matrix finely, raises mechanical strength and also prevents the coarsening of crystal grains and the roughening of texture. Since the three-layered bimetal has a high conductivity and a great mechanical strength, it is excellent as a thermostat metal.

Title: Vapor growth method for group iii-v compound semiconductor
Inventor: ISHIKAWA HIDETO
IPC: H01L21/205
Filed: 1990-02-22
Abstract: PURPOSE:To uniformize characteristics with uniform film thickness of a group III-V compound by enlarging the flow ratio of a group III material carrier gas and by displacing a position of mixture of III and V group material carrier gases from the substrate end to the upstream side of gas flow. CONSTITUTION:A group III material carrier gas is introduced from the first supply port 1, and a group V material carrier gas from the second supply port 2. In this case their introduction into the same reaction furnace 10 equalizes pressures on the Bernoulli theorem so that the group V material carrier gas is led into the supply port 1 on the side of group III material carrier gas in the vicinity of outlet of the supply port 2. It follows that a position of mixture of a group III material carrier gas and a group V material carrier gas is displaced from a vapor growth substrate 3 to the side of supply port 1: this provides an effect equal to that of displacement of the vapor growth substrate 3 from region A to B side. This process enables preparation of uniform film thickness of a group III-V compound to uniformize characteristics, thereby realizing a semiconductor device to a purposed design.

Title: Enclosed motor-driven compressor
Inventor: YANASE SEIGO
IPC: F04B39/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To assemble a compressor without considering positional dislocation of a cylindrical spring by movably inserting the cylindrical spring into a maximum amplitude position of a delivery pipe so as not to resonate in an operating frequency. SOLUTION: Refrigerant gas delivered from a cylinder 1 flows inside of a delivery pipe 4 through a delivery valve chamber 2 and a delivery noise eliminator 3 by reciprocating motion of a piston 6. This refrigerant gas flows to the high pressure side of a refrigerant cycle connected to a delivery connecting pipe 8 through the delivery connecting pipe 8. Vibration of a compression element 10 is transmitted to a sealed vessel 7 through the delivery pipe 4 and the delivery connecting pipe 8, but is damped by a cylindrical spring 15. At operation time, the cylindrical spring 15 of the delivery pipe 4 freely moves to a maximum amplitude position of the delivery pipe 4 by the action of centrifugal force generated with a connecting part of the compression element, the delivery connecting pipe 8 and the delivery pipe 4 as a fulcrum, and resonance of the delivery pipe 4 in an operating frequency can be avoided. Therefore, an inexpensive and silent compressor can be obtained.

Title: Superconducting power supply
Inventor: INOUE TAKASHI
IPC: H01L39/22
Filed: 1992-02-28
Abstract: PURPOSE:To provide a high-duty source current waveform to obtain high device operating efficiency while achieving a substantial decrease in the probability of punchthrough that may cause difficulty in realizing a high-clock-rate Josephson computer. CONSTITUTION:A source current is a sinusoidal current biased by a direct current Iac-Imn that is the difference between the minimum critical current Imn of a superconducting regulator circuit having a Josephson junction and the amplitude Iac of a sinusoidal current. Consequently, a relatively flat part of current waveform is effectively used, and thus a sufficient time is allowed in a current range of +Imn to -Imn supplied to the regulator under a junction reset condition. When this source current is subjected to superconducting regulation under the condition that the critical current is limited, a source current with a duty factor greater than 50% is obtained to increase device operating efficiency.

Title: Denitrating method by reduction with ammonia
Inventor: AKIMOTO HIDETOSHI
IPC: B01D53/34
Filed: 1978-04-14
Abstract: PURPOSE: To restrain the effluent of NH 3 , to increase denitration ratio, and to reduce equipment cost, by, in denitration of exhaust gas, addn. of NH 3  and H 2 O 2  to the exhaust gas which is at a specific temp. range, then by passing the exhaust gas additionally through a layer of metallic oxide catalyst.  
     CONSTITUTION: To exhaust gas 12 (at a temp. not lower than 400°C) discharged from a turbine are added NH 3  14 (in a mol ratio  0.5W3 to NO x ) from nozzles 7, and H 2 O 2  15 (in a mol ratio 0.3W1 to NH 3 ) from nozzles 8 in order to decompose NO x  contained in the exhaust gas in gas phase. By passing the exhaust gas through a conventional metallic oxide catalyst layer 9 (at a temp. 600W250°C), residual NO x  is reduced catalytically with unreacted NH 3  so as to complete the denitration. In that case, because nearly all NO has been oxidized to NO 2 , and the rate of reaction of NO 2  with NH 3  is larger than that of NO, the catalyst layer of smaller volume is sufficient to complete the reaction. In addn., combination of gas phase reduction with N 2 O 2  and NH 3  and catalytic reduction shows synergetic effect, restraining effluent of NH 3  and increasing denitration ratio.

IPC: G01D5/245
Filed: 1993-02-08
Abstract: PURPOSE:To save consumption current of a battery by making a switch switch a path to that path on power failure when a power supply detection part detects power-failure state and then sending the signal of the most significant bit directly to a multiple-rotation counter. CONSTITUTION:Lower bit detection elements LSB-1-LSB-n and synchronization circuits 5 and 10 are not energized on power failure and only a multiple-rotation counter and the minimum circuit required for storing the data are energized by a battery. The power-failure state is detected by a power supply detection part 6, a switch 7 is switched to a path on power failure according to the signal from the detection part 6, and then the output of the most significant bit detection element MSB is directly input to an OR circuit 11 without passing through the synchronization circuit 10. Therefore, the output of the OR circuit 11 is inputted to a multiple-rotation counter 13, multiple-rotation count is performed by the counter 13 as in normal operation, and then the data are inputted to a storage. Only the minimum circuit which is required is energized by the battery on power failure, thus saving the current consumption.

Title: Communication system
Inventor: YAMAMOTO KOJI
IPC: H04W76/04
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To prevent the waste of the assets of a whole system without generating any exceptional processing not by transmitting the information of the temporary disconnection of a data link layer or below and the temporary connection of the re-connection of up to the data link layer to a network layer, and therefore, not by transmitting the information also to the upper layer of the network layer. SOLUTION: In a radio communication system, a ground telephone line between an improved MODEM 11 attached to a user station 2 and a demodulator(DEM) 4 of a center station 1, that is, the line of a data link layer or below repeats disconnection or connection according to the presence or absence of up transmission data. During that time, any layer beyond the network layer of an up line is not disconnected until the end of communication, that is, final line disconnection across the whole layers. In the same way, while at least a line beyond the network layer of the up line is maintained, any down line is not disconnected. Moreover, the factor of the generation of temporary disconnection/temporary connection can be any factor other than the presence or absence of data such as time-out.
