Inventor: SUDO YUKIO
IPC: F04C28/02
Filed: 1985-09-20
Abstract: PURPOSE:To improve responding property, by driving a bypass valve to close or open a bypass hole for feeding a high pressure coolant gas to an operation chamber, and a check valve to break or open the linking of the operation chamber to a low pressure chamber, by a pilot pressure fro ma gas pressure in a high pressure chamber. CONSTITUTION:By applying power to the coil 70 of a switch valve 81 to drive a poppet valve body 67, the linking of the larger diameter part 66A to the smaller diameter part 66A to the smaller diameter part 66B of a valve chamber 66 is cut off, and, at the same time, a ball valve 78 is removed from a valve seat 79. Therefore, passages 75 and 76 are linked together, and a coolant pressure in a high pressure chamber 18 acts on the rear end surface of the valve body 52 of a check valve 49 and on the rear end surface of the plunger 57 of a bypass valve 63, to perform a capacity control operation. Since the sectional area at the top of the smaller diameter part 67B of the poppet valve body 67 is small, the pressure acting on the poppet valve body 67 is also small, and the poppet valve body 67 can be activated instantly even by using a compact electromagnetic coil 70.

Title: Reciprocal moving device for spot welding machine
Inventor: HARA YOSHINOBU
IPC: B23K9/30
Filed: 1981-12-28
Abstract: PURPOSE:To use the power of one system for both automatic reciprocal movement of a moving table and automatic welding of a body to be welded on the moving table, by empolying air to operate the driving source for a rolling body engaging a rack on the moving table of a specifically constituted reciprocal moving device. CONSTITUTION:When a piston lever 31 is put in reciprocation through an air cylinder 30, the rolling body 25 rotates through the engagement between the non- return pawl 33 of a lever 32 engaged pivotally with the lever 31 and a lateral lever 28 to rotate a rolling body 24 through a shaft 23. Its projections 24b engage the rack 12 to move teeth 12 a in a direction (m) and the moving table 11 fixed to the rack 12 in a direction (k) on frames 16 and 17. Since the directions (m) and (k) are different, a spring 26 is compressed to move the shaft 23 in a direction P and a spring 27 is extended. The rolling body 24 once reaching the cut part 14a of a guide plate 14 moves toward and engages the rack 13 by the repulsive force of the spring 26, and the table 11 fixed to the rack 13 moves in a direction l. Therefore, discharge air from a welding machine which uses air for pressure application in welding is sent to the driving source 30 to synchronize the pressure application to a spot with the movement of the rack through a solenoid valve.

Abstract: PURPOSE: To provide a operation speed measuring circuit capable of controlling with the minimum number of terminals and remarkably increase the freedom of circuit design by using this circuit. CONSTITUTION: The operation speed measuring circuit which measures the difference between the propagation delay times of a first path 2 and a second path 3, in which logic gates are connected in series, and confirms that a device on a chip obtains a specified operation speed is controlled by an input signal IN from one input terminal 1, therefore it can be set in the region where the number of terminals capable of arranging is limited to a small number. If a power supply-use terminal is set independent of other circuit in the operation speed measuring circuit, other circuit is capable of independently designing. When the region where the operation speed measuring circuit is set is independent of other integrated circuit design region, the freedom of other circuit design is increased.  If the independent region is the corner part of a semiconductor chip, which is needed to leave as an empty space so far, the freedom of the circuit design is further increased.

IPC: H01L21/304
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To cut out wafers with a uniform quality from an ingot by setting highly accurately the direction of a crystal at a target value. SOLUTION: Deviation between a central axis L1 of an ingot 1 determined by the outer and a normal L2 of a crystal face (100) F2 is measured, and the ingot 1 whose deviation is measured is set at x=0 deg.00' and Y=0 deg.00' on an adhesion tool and is cut. Direction of crystal of the cut wafer is measured to obtain deviation between the crystal face (100) F2 and a cut face F3 . Two deviations are vector-synthesized to obtain the deviation between the central axis L1 of the ingot 1 and the normal L3 of the actual cut face F3 as a system error L and then, the ingot 1 to be cut is rotated to make the system error L4 coincide with the axis X and in addition, the axis X is inclined in such a way that the central axis X of the ingot 1 comes to the position of the system error L4 before operation. Under this condition, the ingot 1 is fixed on the adhesion tool.  The system error is excluded by correcting the angle scale of the ingot adhesion tool with an outer arrangement system.

Title: Reactive power compensator
Inventor: AOYAMA FUMIO
IPC: H02J3/18
Filed: 1986-09-09
Abstract: PURPOSE:To improve the control effect of voltage fluctuation while maintaining the economical properties of a reactive power compensator, by adding a self- oscillation type converter to said compensator to compensate the uncontrollable reactive power. CONSTITUTION:A self-oscillation type converter 20 calculates the reactive power from the current and the voltage which are detected by a current transformer 8 and a voltage detecting transformer 5. A control circuit 30 supplies a current to compensate said reactive power. The converter 20 can be regarded as a constant current source having high response since it turns on and off a gate turn-off thyristor 23 at a high speed and carries out the PWM control. Then the waste time of the converter 20 can be neglected in a frequency area less than several tens Hz that causes the voltage flicker. Furthermore a high frequency can also be compensated by the converter 20. Thus it is possible to improve the control effect of voltage fluctuation while maintaining the economical properties of a reactive power compensator.
