Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a valve driving device which can be used when there is no supply source of pressurized air or even when there is no pressurized air and there is a danger that flammable gas such as natural gas in a high pressure pipe line is released into the atmosphere and can reduce the weight of an actuator, produce high power, make the whole device compact and inexpensive and fast open and close a valve. SOLUTION: A piston rod 22 is moved forward by sending fluid from a tank 5 pressurized to a predetermined pressure by a pump 6 into a hydraulic cylinder 21. The fluid in the hydraulic cylinder 21 is discharged by opening an opening and closing valve 8 provided in a return pipe 3b between the hydraulic cylinder 21 and the tank 5. The piston rod 22 is moved backward by sending fluid in the high pressure part of a pressure increasing unit 24 into a sub- cylinder 23 by the pressure of fluid in the low pressure part of the pressure increasing unit 24 compressed by the forward movement of the piston rod 22.

Title: Rectilinear reciprocating device
Inventor: FUJIMURA TAKESHI
IPC: F16H21/20
Filed: 1989-02-23
Abstract: PURPOSE:To make it possible to adjust a stepless change of stroke value by constituting it with a driving block, a reciprocating block, a front fitting holding a guide mechanism and a sliding rod, a stroke value adjusting means of this reciprocating block and an input shaft. CONSTITUTION:A sliding groove 6K coupling an eccentric drive shaft part 5hc of a driving block being interlocked and reversed by rotation of an input shaft 3 is reciprocated as pushing or pulling while being slidden in the vertical direction in a passive frame 6W, whereby a reciprocating block 6 is reciprocated sideways. Then, a stroke value adjusting means 8 is operated and a locus direction where the sliding groove 6K is shifted is changed, and thereby a stroke value of the reciprocating block 6 is freely selected, and when the direction is paralleled with a center line of a sliding rod 6S, the maximum value is secured and at time of orthogonality, it becomes minimized. In this connection, since it performs one stroke per rotation of the input shaft 3, a reciprocating speed comes to the highest at time of its maximum stroke, but it comes to the lowest at time of the minimum stroke.

Title: Staircase wave generating circuit
Inventor: KAWAMURA TAKETOMO
IPC: H03K4/02
Filed: 1988-02-26
Abstract: PURPOSE:To simplify a circuit by providing a logical gate circuit corresponding to respective plural switch elements to output alternatively plural divided voltages formed by a resistance ladder. CONSTITUTION:In a staircase wave generating circuit, when a staircase wave approximate to a sine wave is formed, outputs Q4-Q1 of a counter circuit COUNT is 0000 and a switch S4 is turned on, a fourth divided voltage is outputted from the maximum value corresponding to a switch S1. Consequently, to a NAND gate circuit corresponding to the switch S4, an output, the inerse of Q4 of the most significant bit to show the positive half cycle and the signals, the inverse of A and B through inverter circuits N7 and N8 is supplied. For this reason, at the time of a timing T1, the switch S4 can be turned on by the 00 of the signals A and B corresponding to the 0000 of counting outputs Q4-Q1. Thus, the output signal outputted through switches S1-S8 is outputted through an arithmetic circuit OP made into a voltage follower mode.

Title: Clutch control device
Inventor: HIKITA MANABU
IPC: F16D25/08
Filed: 1980-03-31
Abstract: PURPOSE: To prevent the generation of tooth biting sounds at the gearing section of a variable speed gear by a method wherein the clutch releasing fork is kept pushed when the variable speed gear is in the neutral position and the clutch is kept interrupted irrespective of a clutch pedal stepping operation.  
     CONSTITUTION: When the clutch pedal is stepped on prior to the initiation of an idle operation, an electromagnetic valve 7 opens since an ignition switch 23 is OFF and a piston 11 of the first piston 6 is caused to reciprocate. Accordingly, the oil in a cylinder 9 is fed under pressure to the second piston via oil passages 15 and 16 and  the clutch is interrupted through the clutch release fork 3. When a switch 23 goes  ON in the above mentioned state (in which a neutral switch 24 is ON), the electromagnetic valve 7 is closed. Accordingly, even when the pedal 5 is released after  the engine is started, the pistons 11 and 26 are kept at positions in which they  assume their return strokes and the clutch is kept at its interrupted or unlocked  position since both of the oil passages 15 and 16 are closed.

SOLUTION: A fatigue measuring gauge 8 is made up of a gauge base material 1, and a film material 5 having a large number of elliptical cutouts 3 that has been formed on the gauge base material 1 through an adhesive 2. In this case, the film material 5 is formed by the photoprint method which is used as one of the manufacturing method of a resistance wire strain gauge. In measuring the strain of a measuring object 6, a fatigue measuring gauge 8 is stuck on the surface of the measuring object 6 through an adhesive. When the measuring object 6 is subjected to a respected stress, the gauge base material 1 is extended or compressed in following up with the extension and compression of the measuring object 6, and a corresponding repeated stress is transmitted even to the film material 5.  As a result, the film material 5 is successively introduced to fracture from the positions of cutouts 3 that have been machined in the film material 5.

Inventor: MORI KAZUNORI
IPC: G11B5/09
Filed: 1994-03-15
Abstract: PURPOSE:To facilitate the detection of an offset quantity over a wide range of a track pitch. CONSTITUTION:A pattern 130 offset to an inner side, a pattern 140 offset to an outer side and, if necessary, a polarity pattern 150 which has the width larger than the widths of the patterns 130 and 140 are recorded in a track direction at the specific cylinder position of each data plane of a disc medium. If only a reading signal V1 or V2 is obtained, an offset measuring means 102 measures the offset again after a head is returned in a direction of removing the offset. In this case, the measured offset value is the sum of the returned distance of the head and the offset quantity which is finally obtained from the signal V1 or V2. When both the reading signals V1 and V2 are not obtained, the existence of a polarity information reading signal V3 is decided by the polarity pattern 150 and, if it exists, a certain quantity of offset is performed in the direction opposite to the polarity pattern 150 and then the offset is measured again. If the reading signal V3 does not exist, a certain quantity of offset is performed to a non-recorded side and then the offset is measured again.
