Title: Enclosed cycle type gas turbine employing coldness of liquefied natural gas
Inventor: DEWA KOU
IPC: F02C1/10
Filed: 1979-11-07
Abstract: PURPOSE: To reduce the pressure difference between the interior and exterior of a heat transfer tube extending in a heater for heating a working medium, to decrease the stress of the heat transfer tube to make the temperature of the working medium higher than that in conventional cases, by pressurizing combustion gas in the heater.  
     CONSTITUTION: A working medium compressed by a medium gas compressor 1 is heated by a regenerative heat exchanger 5 and heated further by a heater 4 to rotate a gas turbine 2. The medium exhausted from the turbine 2 is returned to the compressor 1 through the regenerative heat exchanger 5 and an LNG evaporator 6. In the heater 4, fuel supplied from a burner 15 is burned with high-pressure air supplied from a high-pressure duct 14 so that the combustion gas flows through a combustion chamber and a contact heat transfer section as the pressure of the gas is remains high. The combustion gas heats a heat transfer tube 17. After that, the combustion gas is discharged from a duct 14. This results in reducing the stress of the heat transfer tube 17 to the maximum extent.

Title: Superconductive wire material
Inventor: YASUNAGA TOSHIO
IPC: H01B12/12
Filed: 1987-06-11
Abstract: PURPOSE:To obtain a compact superconductive wire material by providing a superconductive wire material at a pipe inside wall and letting refrigerant flow inside a hole. CONSTITUTION:A superconductive material 23 of Cu-Y oxide is provided at the inside face of a hollow Cu pipe 22 and an insulator 21 is provided at the outside face. For pipe, SUS will do. Refrigerant G is sent from a cooler 31, which enters from one end of a superconductive wire material 6a and flows inside the pipe and comes down through a nonconductive connecting pipe 32 and enters an other superconductive material 6b and then returns to a cooler 31. Since the power transmission distance is determined by the thermal load, in case of long distance, this loop is repeated. According to this constitution, a superconductive apparatus can be constituted only by providing a cooler at the pipe end.
Patent JP-S631837-A (JP)
Title: Actuator
Inventor: TAKAISHI TATSUYUKI
IPC: F16H1/28
Filed: 1986-06-20
Abstract: PURPOSE:To simplify the structure while satisfying the function and to reduce the size and weight, by supporting an input internal gear idly within a setting stroke range on the housing and stretching a returning spring for resetting one of the input or output internal gear and an arm member in a planetary gear mechanism to a relative neutral position between said internal gear and the arm member. CONSTITUTION:The operational reaction of a planetary gear mechanism 40 is born by stopping an input internal gear at one end of a setting stroke so as to displace an arm member 44 and the input internal gear 42 relatively. When an actuator 10 stops, the arm member 44 and the input internal gear 42 are reset to a relative neutral position by the energizing force of a returning spring 24 so as to rotate the input internal gear 42 from one end to the other end of said setting stroke. Consequently, when an external force is inputted, the input internal gear 42 idles in the setting stroke and follows to the external force, thereby the external force can function lightly without subjecting to resistance. Since a light operation can be achieved without providing a clearance in an operation transmitting system, the structure can be simplified and the size and the weight can be reduced with the function being satisfied.

IPC: C21D9/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a rotor for a disc brake decreased in cost and having high friction resistance. SOLUTION: After gas soft nitrating treatment is applied on a material formed of JIS FC250 formed through sand mold casting finished in a rotor shape, the material is heated and held at temperature higher than an A1 transformation point and lower than an eutectic temperature and by causing isothermal transformation of a nitrogen diffusion layer formed through nitriding and a matrix through holding of it in a heat bath at a given temperature, a rigid nitrogen compound layer is formed on the surface of the rotor. Further, since the nitrogen diffusion layer at the lower layer of the nitrogen compound layer and the matrix are brought into a bainitic texture high in hardness, wear resistance of a rotor is improved.

Filed: 1988-06-12
Abstract: PURPOSE:To realize a wobbling state of a light beam at a reduced power consumption by using an optical system constituted at a comparatively small scale so as to displace a moving body with small moment inertia. CONSTITUTION:A support member 23 supporting an objective lens 21 in a moving optical system 20 is rocked by utilizing a torsion in a hinge 52y of a moving support member 52 supporting the member 23 and a laser light beam through the objective lens 21 is made incident on the recording track on the optical disk under the wobbling state. Then the wobbling state of the laser light beam is obtained by displacing the moving section whose moment inertia is made comparatively small. Thus, the power consumption to obtain the wobbling state of the laser light beam is reduced.

Filed: 1989-06-09
Abstract: PURPOSE: To improve a response speed and the reliability and to extend a detection range by using an inverse spread device that spreads and demodulates a received signal to keep synchronization between a pseudo signal (PN) code generated by a PN code generator and a PN code of the received signal. CONSTITUTION: When a PN code pattern generated from a PN code generator 213 is synchronous with a PN code pattern of a transmission signal, a difference between both patterns is zero. When not, some voltage is outputted from a subtractor 207, and fed to an active low-pass filter of a next stage consisting of an amplifier 211 and a capacitor 210 or the like. A cut-off frequency of the active low-pass filter is selected to decide a response speed of a feedback loop in a delayed lock loop(DLL) circuit. The feedback loop acts like keeping the synchronization state. Since the synchronization of the PN code is attained by using a voltage at a control terminal of a VCO at a high speed with reliability, the synchronization of PN codes at a high speed is realized.
