Inventor: ITO SATORU
IPC: F16K17/00
Filed: 1985-07-25
Abstract: PURPOSE:To drive and control a valve plug even with a small driving section and finely control the displacement of the valve plug by driving the valve plug with the reduced driving displacement quantity of the driving section and the increased driving force respectively. CONSTITUTION:The motor rod 3a of a linear pulse motor 3 is digitally moved downward step by step based on control pulse signals to press and drive a small-diameter piston 7. Then, a large-diameter piston 8 is likewise moved downward via the operating oil in an operating chamber 6. In this case, the displacement quantity of the large-diameter piston 8 is reduced than that of the small-diameter piston 7, and the driving force is increased than that of the small-diameter piston 7. Accordingly, the large-diameter piston 8 presses and drives a poppet valve 14 with the reduced displacement quantity of the motor rod 3a and the increased driving force.

Abstract: PURPOSE:To obtain pressure accumulating and damping effects through an additional part of volume and prevent the intrusion of combustion gas into the end of a nozzle, by providing, in the main unit of a valve, the additional part of volume communicated to a fuel supply path in the valve through a fine hole or the like. CONSTITUTION:In a fuel injection valve, when the pressure of fuel oil in a nozzle chamber 1 decreases lower than the pressure of combustion gas in a cylinder, the combustion gas intrudes into the valve from the cylinder, and the intruding combustion gas is allowed to flow through the gap between a nozzle valve 2 and a nozzle holder 3 and through a spring chamber 4, appearing as bubbles in a leakage oil pipe 5. An additional part of volume 11 is provided to be communicated through a fine hole 10 in the nozzle holder 3 located in the inlet part of a fuel supply path 9 communicated to a high pressure fuel line 6 of said valve. A pressure wave from a fuel injection pump and a reflective wave from the part of a nozzle 8 are absorbed in this additional part of volume 11, thus increasing the residual pressure in a pipe. In this way, the combustion gas can be prevented from intruding into the end of the nozzle 8.

Title: Electronic component mounting and dismounting apparatus
Inventor: KOMATA KAZUO
IPC: H05K3/34
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To uniformly heat an electronic component by coupling a heater unit having a heating face for melting solder sticking to the underside of the electronic component with a hanging means by a force smaller than the gravitational force on the weight of the heater unit so that the heater unit can freely oscillate, and positioning the heater unit so that it is in parallel with the top face of the electronic component. SOLUTION: A hanging means 16 provided on a movable plate 10 is formed by winding a constant force spiral spring 16b on a pulley 16a. A rod 13d is protruded from the top face of a heater block 13 at the center of the top face, and is inserted into a through hole 12a with play with the tip of the inserted rod coupled with the tip of a constant force spiral spring 16b through a ring 16c. A heater unit H is hung so that almost all of its own weight is canceled out by tensile strength from the constant force spiral spring. As the result, the heater unit acts to exert as light pressing force as the weight of a heating block 14 and can freely oscillate. Therefore, planar contact is ensured even if the top face of a semiconductor chip 2 is inclined.

Title: Image forming device
Inventor: NAKANE EIJI
IPC: G03G15/16
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To enhance durability, to prevent toner grains from being splashed and to form an excellent image by providing a device with a second electrostatic transfer field imparting body transferring a toner image on a transfer material by an electrostatic field whose field distribution is narrow. SOLUTION: The formed images of respective color toner components are successively transferred at the prescribed positions of a recording paper from the circumferential surfaces of photoreceptor drums 1C-1K by electric fields generated by transfer rollers 11C-11Y or a transfer brush 11K. At an image forming part 20K where the toner image of the K component is transferred, the splash of the toner grains is controlled by restricting the electric field generated by the brush 11K because a voltage is applied at a transfer position. At image forming parts 20C-20Y where the toner images of the C, M and Y components are transferred, the some toner grains are splashed by the wide density distribution of the electric field by the rollers 11C-11Y.  However, since the splash is almost inconspicuous in reality, an effect exerted on the image forming action is reduced, to such an extent that it can be ignored.
