Title: Cooling system
Inventor: TOKUE RINZO
IPC: F25B1/00
Filed: 1992-06-23
Abstract: PURPOSE: To prevent the generation of vapor condensation in an object to be cooled and achieve a safe liquid cooling by providing a constant gas flow device which can operate at a prescribed temperature higher than ambient temperature under the steam pressure of a low boiling point refrigerant as reference pressure in the feedback line of a cooler. CONSTITUTION: A compressor 1 compresses a low boiling point refrigerant. Then, hot steam becomes liquid in a condenser 2, which passes through a filter 3 and flows to a cooler 5 on which a circuit board 4 is mounted. In this case, in the feedback line of the cooler 5, a constant gas flow device 10 is disposed. The constant gas flow device 10 can operate at a prescribed temperature higher than ambient temperature under the steam pressure of a low boiling point refrigerant as reference pressure, so that it controls the temperature of the refrigerant applied to an object to be cooled. Namely, the constant gas flow device 10 controls the pressure of the low boiling point refrigerant composed of a gas or liquid through a film 13 by the pressure of a volume part 16 in the passage chamber 14 of a passage part 11.  Thus, the low boiling point refrigerant is maintained in the reference pressure to prevent vapor condensation from being generated on the object to be cooled.

Title: Clutch control device for mechanical supercharger
Inventor: NISHIMURA EIJI
IPC: F02B39/12
Filed: 1989-07-20
Abstract: PURPOSE:To improve acceleration performance while suppressing generation of a shock at the time of steady running by controlling the connection degree of a clutch in a manner,wherein the lower is a speed change shift the stronger the connection degree is controlled, in a half-clutch condition at the time of transfer of a supercharger from its inoperative region to operative region. CONSTITUTION:In an engine 2, a mechanical supercharger 5, driven by an engine output shaft through an electromagnetic clutch 11, is provided in an intake passage 3 and actuated in a predetermined operative region. Here the electromagnetic clutch 11 is controlled to a half-clutch condition by a controller 12 at the time of transfer of the supercharger 5 from its inoperative to operative region. While the lower is a speed change shift in an automatic transmission 15 the stronger a connection degree of the electromagnetic clutch 11 is controlled in the half-clutch condition. ln this way, deterioration of a running feeling is prevented by effectively reducing a shock, when the electromagnetic clutch 11 is connected, at the time of steady running in a high speed change shift. While in a low speed change shift, good acceleration performance is obtained with a supercharge effect by the supercharger 5 promptly appearing.

Title: Current mirror circuit
Inventor: ISHIGURO KAZUHISA
IPC: H03F3/343
Filed: 1982-10-28
Abstract: PURPOSE:To reduce feedback from the output side to the input side at the separation of bases of transistors (TRs), to improve the accuracy of output current and to allow the titled circuit to operate down to a low voltage by separating the bases of the TRs having the relation of a current mirror each other. CONSTITUTION:If it is defined that the mirror ratio of an input side TR6 and an output side TR8 is 1, current flowing into an input current source 7 is Ii and the base current of the input side TR6 is IB, the Ii flowing into the input current source is the sum of the collector current beta1.IB [beta1 is the current amplification factor of a pnp TR] and the base current of a control TR12. The collector current IO of an output side TR8 becomes IO=beta1.IB. Therefore, the difference is (1/beta1)(1+3/beta2)I2. Since the beta1 is about 40 and beta2 is about 200 generally, the differece current is 0.0251IB and extremely small which can be almost neglected. Thus, accurate output current can be obtained and the operation can be stabilized.

Title: Liquid fuel vaporizing combustion apparatus
Inventor: HATAKEYAMA MAKOTO
IPC: F23D11/44
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To enable utilization for the vaporization of a liquid fuel at the ignition by a method wherein a heat storage section is provided in a combustion device, from which heat, stored is transmitted to a vaporizing part at the ignition and quickly raises the temperature of the vaporizing part to store combustion heat during the combustion. SOLUTION: The temperature of a vaporizing part 7 is raised by heating with a heater 10 and a liquid fuel 3 is pressurized by a pump 4 to be injected through a nozzle 6 from a fuel tank 2 and vaporized by the vaporizing part 7. Then, air is sent and is mixed with the vaporized fuel by a mixing part 11 and the mixture is sent to a flame hole 13 of a burner head 12 to be ignited by the action of an ignitor 14. With the continuation of the combustion, a heat receiving part 9 is heated by a flame 15 to raise the temperature thereof and the transferring of combustion heat is started from the heat receiving part 9 to the vaporizing part 7 while the outputted of the heater 10 is lowered according to the amount of the transmitted combustion heat. Upon the start of the combustion, a heat storage section 16 operates an actuator 19a to open open/close lids 20a and 20b.  A combustion gas passes through the heat storage section 16 and heats a regenerator body to raise the temperature thereof. This eliminates the need for electric energization of the heater thereby allowing the lowering of a running cost.
