Title: Hydraulic circuit
Inventor: AOKI YOICHI
IPC: F15B11/08
Filed: 1995-05-16
Abstract: PURPOSE: To prevent the pressure of working fluid fed from a directional changeover valve to an actuator from falling by changing an opening section of a variable restriction flow passage connected to a bypass port on the outlet side of the directional changeover valve according to a prime mover driving a main pump. CONSTITUTION: When a pump port and a changeover port of a proportional solenoid valve 25 are communicated to each other, pilot working oil from a pilot pump 4 is fed to a pilot port 24a through pilot working oil pipes 18, 31, the proportional solenoid valve 25, and a pilot working oil pipe 32. By movement of a spool toward the other stroke end, the opening area of a flow passage communicating an inlet side port and an outlet side port of a variable restriction valve 24 to each other is contracted. Thereby, communication of working oil from a main pump 2 to an oil leading tank 9 through a directional changeover valve 3 is restrained, and when the spool of the directional changeover valve 3 reaches the operation beginning point of an actuator, working oil pressure enough to actuate a cylinder 1 is fed from the directional changeover valve 3 to a cylinder 1.

Abstract: PURPOSE: To keep a compressor properly cooled at all times by providing a piping connecting the cooling port of an exterior heat exchanger and the central part of an injection pipe pressure reducing system through a check valve.  
     CONSTITUTION: In the cooling mode, the refrigerant flows along the piping as shown by the arrows of continuous lines. The pressure of a point N on the cooling port side of an exterior heat exchanger 13 is a little higher than that of an intermediate point L. Accordingly, the high pressure refrigerant flows from the point N through a check valve 22 and a second injection capillary tube 20 and injected into the compressor 11. In the heating mode, the refrigerant flows along the piping as shown by the arrows of dotted lines. In this case, the pressure at the point L being higher than the pressure at the point N, the high pressure refrigerant flows from the point L through a first and second capillary tubes 21 and 21 into the compressor 11. The injection flow rate is increased in the cooling mode and reduced in the heating mode by properly selecting the flow resistance of the first injection capillary tube 21

Title: Driving circuit for stepping motor
Inventor: ARAI SATOSHI
IPC: H02P8/02
Filed: 1979-09-13
Abstract: PURPOSE:To reduce the chip area and the consumpted current in an integrated circuit by replacing the NPN transistors in the stepping motor driving circuit in the integrated circuit for watches by VMOS transistors. CONSTITUTION:The output of an oscillating circuit 2 which receives a current from a constant current circuit 1a becomes the control signal for a driving circuit 4 of a motor M by frequency dividing circuits 3a and 3b which receive the current from a constant current circuit 1b. The driving circuit 4 is constituted by PNP transistors Tr3 and Tr5 which are fabricated in the same process for electrostatic induction transistors at the same time in the integrated circuit and VMOS transistors Tr7 and Tr8 instead of conventional NPN transisters. In this case, since the processes for forming the electrostatic induction transistors and the NPN transistors are utilized, a new mask is not required, the cost for forming the VMOS transistors is not increased, processing can be performed inexpensively, and the area of the driving circuit and the consumption current can be reduced.

Title: Semiconductor memory circuit
Inventor: INUKAI HIDEMORI
IPC: G11C11/34
Filed: 1984-06-08
Abstract: PURPOSE:To eliminate the limitation for the active period of a row address strobe signal by holding the potential of a row line via a pull-up circuit based on the frequency signal that compensated the drop of potential for the row line produced in a prescribed period. CONSTITUTION:A chip selection clock is produced from a chip selection signal generating circuit 5 as a frequency signal that compensates the drop of the row line potential while the row address strobe signal given from a row address strobe signal is kept active. Thus a monostable multivibrator 6 is triggered. A pulse PHI1 delivered from the trigger 6 is supplied to a pull-up circuit 4. Therefore the row line WLi selected every cycle when the chip selection signal is activated is charged to the circuit 4. Thus the potential level of the circuit 4 is kept. This can eliminate the limitation for an active period of the row address signal. As a result, a semiconductor memory circuit can work without giving any minitation to a page mode action.

Abstract: PURPOSE:To prevent a hydraulic material, which is used for forming, from sticking to a forming material, to prevent the forming material from being taken out with the hydraulic material stuck to it and to improve workability, in reference to a hydraulic press forming machine by which a thin plate is formed. CONSTITUTION:After forming dies like a male base 3, a hydraulic chamber 4, etc., are attached and fixed in the slide 1 and a bolster 2 of the press respectively, the forming material 9 is arranged on the upper surface of a lower blank holder 8. The fluid to be used is a mixture of an adequate amount of a thickener, rust preservative and surfactant with water. By the effect of the surfactant, the surface of the forming material is hardly wet even when the surface is brought into contact with the fluid during forming. The fluid 10 is filled in the hydraulic chamber by a supply device 12. An adjusting apparatus for supply and forming pressure may be an ordinary water and oil pressure apparatus since the mixed quantity of the thickener is small and the viscosity of the fluid is low. The press thus structured is operated to lower the slide and push down the forming material the tip end part 3' of the male die; consequently, the fluid pressure in the hydraulic chamber is raised, and the forming material is press-formed in the shape of the male die.
