Patent JP-S5958120-A (JP)
Title: Three-valve engine
Inventor: YATANI CHIKAYOSHI
IPC: F02B29/06
Filed: 1982-09-24
Abstract: PURPOSE:To prevent the output of an engine from dropping, by installing an exhaust port in a cylinder or disposing a valve side by side, while intercepting the outside air from admission. CONSTITUTION:A four-stroke-cycle engine completes its exhaust by means of pressure out of a piston 10 but the explosion pressure is left behind inside a cylinder whereby the pressure imposed on the piston is large, causing the engine output to go down to some extent anyway. So, an exhaust port 5 is installed in the cylinder or a valve 6 is disposed side by side, aiming at intercepting the outside air from incoming, so that the pressure inside the cylinder after explosion is discharged; any drop in the engine output is thus prevented.

Title: Gas cutoff valve
Inventor: ISHIGAKI YOICHIRO
IPC: F16K17/36
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To easily adjust the sensitivity of a moving piece being removed from a bottom part when external vibration is applied by forming the shape of the bottom part of an inclined section to be freely changed in a device for keeping a valve open while the spherical moving piece is placed on the pot-like inclined section provided in a main body. SOLUTION: A gas cutoff valve 1 is constructed in such a manner that a valve seat 14 for surrounding a valve hole 14a for communicating a gas inlet section 12 and a gas outlet section 13 with each other is formed in a valve casing 10 as a main body, and a valve body 2 freely moved up and down is housed in its lower part. In this case, a moving piece 3 is placed between the lower side of the valve body 2 and an adjusting member 4 having a pot-like inclined section 43 inclined downward toward the inside. In the lower surface of the valve casing 10, a bottom member 11 is attached by a screw 41 so as to be detached, and a spacer 42 is provided between the adjusting member 41 and the bottom member 11.  In the adjusting member 4, a holding hole 44 for holding the piece 3 in the bottom part of the inclined section 43 is formed, and as its diameter is increased, the piece 3 is buried in the holding hole 44 deeper, and thus sensitivity to vibration is reduced.

Title: Liquid jet recording device
Inventor: TERASAWA HIROHARU
IPC: B41J2/175
Filed: 1989-06-29
Abstract: PURPOSE:To ensure stable delivery and recovery by providing an ink supply path connecting to an orifice and a pressurizing means and at least one connecting path connected to an ink containing means. CONSTITUTION:A diaphragm 40 is pressed by lowering a pressing member 39, whereby ink in the diaphragm 40 is extruded to an ink supply path 32B, and an air stagnating in the upper part of the ink supply path 32B is discharged to an air layer 38 in an ink containing part 33 through a connecting path 50. When the ink supply path 32B is filled with the ink with a pressurizing operation, a flow resistance is increased for the ink passing through the connecting path 50. In this manner, the ink, bubbles in a nozzle, and the like are discharged from a delivery port by a pressurizing force, thus, a recovery processing is accomplished. In this case, in an initial stage of a pressurizing operation conducted by a pressurizing means, a part of the ink is fed into the ink containing part 33 in addition to air through the connecting path 50 to become a circulating state; this state reduces an ink amount to be delivered from a nozzle part 32 by every pressurizing operation.

Filed: 1982-09-29
Abstract: PURPOSE:To restore a contact of a display relay automatically without informing the fault of the relay contact to the controlling side, by turning on/off the relay contact automatically at the generation of the defect of the contact. CONSTITUTION:A timer circuit 20M inputs an input defective signal 20A which is an output from an OR gate 19, to check whether the continuous time of the input defective signal 20A exceeds a prescribed time T1 or not. The time T1 indicates whether the continuous time of the input defective signal 20A reaches the time requiring general on/off or not, and if the T1 is exceeded, the timer circuit 20M outputs a general ''ON'' signal 20C and a general ''OFF'' signal 20D. Thus whether the continuous time exceeds T1 or not is checked at the generation of a fault, and if the time does not exceed the time T1, the operation is discriminated as normal state and the normal operation is continued. If exceeding the time T1, relays 33, 34 are turned on/off. As the result, defective continuation or not is checked, and if the defective state is continued, the defective state is informed, and when not continued, normal restoration is discriminated.
