Title: Valve stopping device of variable displacement type engine
Inventor: KIMURA TAKAYUKI
IPC: F01L13/00
Filed: 1982-07-31
Abstract: PURPOSE:To perform reliable switching between operation and non-operation without malfuction, by installing a relief valve on a discharge passage interconnecting the discharge port of a low-pressure chamber to tank port. CONSTITUTION:Discharge ports 45 of tappet valve devices 5a and 5b are connected with each other, and are connected to an oil pan 59 through a discharge passage 61. From a discharge end 63 of a discharge passage 61, a relief valve 65 connected to the oil pan 59 is disconnected with a set pressure. When, by the piston action of a slide body 13, the pressure within a high-pressure chamber 29 exceeds the set value, the relief valve 65 is opened to decrease the pressure within a discharge circuit 61. This prevents a suction and exhaust valve 21 from malfunction caused by a high oil pressure exerted on other stopped cylinders and enables reliable stop of the suction and exhaust valve 21 even if the number of revolution of an engine is as high as about 3,500rpm.

Abstract: PURPOSE:To obtain a low-cost, low-noise, odorless, and high-speed device, by a method wherein when a print mode is designated, a heating element and a thermal transfer recording medium are brought into slide contact with each other to selectively transfer a thermo-transferring ink to a recording paper ; when a process mode is designated, a film layer is brought into slide contact with the heating element to conduct a selective perforation on a thermal-perforation original form. CONSTITUTION:In a print mode, an ink donor sheet 27 laid over a recording paper 35 comes into contact with a heating resistor 15R at the side of a film base 33 and applied with heat pulse according to image information. A portion of an ink layer 34 applied with the heat pulse is transferred to the recording paper 35 in a sublimated or hot-melted condition and set up. In a process mode, a stencil base paper 28 passes between a thermal head 15 and a platen roll 16 while allowing an orienting plastic resin layer 26 thereof to come into contact with the heat resistor 15R. At this time, the ink donor sheet 27 is used as a carrier for the stencil base paper 28. A portion of the orienting plastic resin layer 26 applied with heat pulse by the heating resistor 15R has an open hole due to the heat and shrinks to wind round a surrounding fiber etc. ; in this manner, a perforation is carried out.

Title: Method for joining metallic pipe
Inventor: KUWABARA YUKINORI
IPC: B23K20/14
Filed: 1994-05-25
Abstract: PURPOSE:To rapidly, easily and efficiently join metallic pipes and piping parts at a low temp. by heating a joint part inserted with an inert member at a specific temp. to melt the insert member while maintaining the internal pressure of the metallic pipes and the wiring parts at an atm. pressure or above by using an inert gas, thereby diffusion joining both. CONSTITUTION:The insert member 6 is held between the pipe 9 and the pipe 10 and is fixed to clamps 2 and 3; simultaneously, pressurizing force is acted on the joint surfaces by a pressurizing device 7. The gaseous argon commonly used for preventing oxidation and controlling the internal pressure of the pipes is thereafter admitted from gas nozzles of shielding gas nozzles 5 and a purging gas nozzles 8 and the joint part is heated to a temp. lower than the m.p. of the pipes 9, 10 and higher than the m.p. of the insert member 6 by a high-frequency induction heating coil 4, by which the pipes are joined. The joint part joined in such a manner is extremely smooth and the insert member 6 is diffused into the metallic pipes 9, 10. The state that the insert member is not detectable in terms of metal structure is thus attained.

Abstract: PURPOSE:To simplify circuit constitution and to facilitate IC-implementation by constituting the 1st and 2nd differential amplifying circuits by the combination of transistors (TR), and obtaining an output from the connection position between their collectors and bases. CONSTITUTION:Transistors (TR) Q1 and Q2 constitute the 1st differential amplifying circuit 1, and TRs Q3 and Q4 constitute the 2nd differential amplifying circuit 2. Collectors of the TRs Q2 and Q3 are connected in common to a constant current loading circuit and also connected to their bases. Therefore, 100% of output signals of the differential amplifying circuits 1 and 2 is fed back negatively. On the other hand, an output signal Vout is obtained from the connection position between their collectors and bases. Emitters of the TRs Q1 and Q2 are connected to a power source Vcc through a TRQ5 and a resistance R1, and emitters of the TRs Q3 and Q4 are connected to the power source Vcc through a TRQ6 and a resistance R2. The 1st input signal Vin1 is applied to the base of the TRQ1, and the 2nd input signal Vin2 is applied to the base of the TRQ4 to putting either of the TRs Q5 and Q6 in operation selectively, thus obtaining an output signal Vout which responds to either of the Vin1 and Vin2.

Abstract: PURPOSE:To improve the picture quality by providing such a lens that intervals (pitch) between adjacent light emitting elements at adjacent parts of a light emission tube appear to be small. CONSTITUTION:The Fresnel lens 5 which is fixed on the front surface of a light emission tube 3 with an adhesive, etc., functions to form virtual images 100A of respective light emitting elements 100 at positions deviating toward the outer peripheral edge part of the light emission tube 3.

The pitch l0 at the join part of the light emitting tubes 3 is reduced apparently to the pitch l1 by the Fresnel lens 5 to decrease the pitch l1 of the light emitting elements 100 without making the pitch irregularity conspicu ous. Consequently, the picture element can be improved.

Title: Confluent circuit using operating valve
Inventor: TAKIGUCHI TAKAHIDE
IPC: F15B11/17
Filed: 1995-05-09
Abstract: PURPOSE: To reduce the loss of power by providing a flow rate control valve which allows the flow rate to flow to an actuator in response to the pressurized oil of the first, second pumps, an unload valve which allows a surplus of the flow rate to flow into a tank by the differential pressure at the time when the flow control valve operates and the differential pressure across a throttle on the pump delivery side, and a confluent valve which is switched by the differential pressure of the unload valve and allows the delivery flow rate of both of the pumps to join. CONSTITUTION: A confluent valve 17 which allows the flow rate of the second pump 2 to join the flow rate of the first pump 1, is switched by the differential pressure of the first flow control valve 8, an unload valve 7 which allows a surplud of the flow rate to flow into a tank 28 by the differential pressure across the first throttle 5, the differential pressure caused by the operating quantity of the second flow control 14, and the differential pressure across the third throttle 11 of the pump 2. Thus, when the flow rate needed for operating an actuator 9 is the delivery flow rate Q11 of the pump 1 or below by operating the control valve 8, the confluent valve 17 is at a drain position to drain the whole delivery flow rate Q12 of the pump 2 into the tank 28 under non-load pressure without passing through the unload valve 7.  Thus, the pump 2 requires no useless operation, and thus the loss of power is not generated.
