Abstract: PURPOSE:To reduce the stepping force of a pedal, by energizing the pedal in direction of reducing its stepping force by means of an assist piston which operates itself upon receiving delivery pressure at the delivery port of a valve body in time of pedal stepping on. CONSTITUTION:When a brake pedal 13 is stepped on, a piston 25 is set in motion and an exhaust valve seat 38 takes its place to a valve member 34 and afterward, the valve member 34 comes off a feed valve seat 39. And, compressed air in a first input chamber 36 flows into the inside of a first control pressure chamber 27 and further the compressed air flows into one side of brake actuators by way of a first output port and simultaneously flows into a relay chamber 45. At this time, the compressed air in the control pressure chamber 27 also flows into the inside of a pressure air chamber of a stepping force reducing device 20 by way of a pipe 87 whereby an assist piston 82 is driven toward the upper part against a spring 84. Therefore, the pedal 13 receives turning force in the stepping direction via a roller 18, thus stepping force is reduced. In addition, with the compressed air in the relay chamber 45, a piston 47 is operated so that the other side brake system is set in motion in an interlocking manner.

Title: Coupling device for piping
Inventor: SHIBABUCHI TOSHIO
IPC: F16L33/28
Filed: 1993-03-15
Abstract: PURPOSE:To reduce a cost by reducing the size of a fastening member in the direction of an axis. CONSTITUTION:In a coupling device for a piping, an annular groove 20 is formed in the inner surface of the end part on the inlet side of a flexible pipe insertion hole part 16 formed in a fastening member 15. An annular packing 19 in an L-shape in cross section is fitted in the groove 20 in a state that the tip thereof is protruded from the groove 20. A packing 19 is pressed in an anti-slip-off state in the groove 20 through the force of a C-shaped spring body 21 formed of a wire rod. Since the packing 19 is formed in an L-shape in cross section, the groove 20 in which the packing 19 is fitted may be small and a fastening member 15 is reduced in the direction of an axis. When a flexible pipe 10 is moved within the flexible pipe insertion hole part 16 of the fastening member 15, even in a case a force is exerted on the packing 19 in a direction in which the packing is slipped out from the groove 20, the packing 19 is supported in an anti-slip-off state through the force of the spring body 21 and prevented from being slipped out from the groove 20.

Title: Fuel-injection wherein fuel is injected directly into cylinder
Inventor: NAKAGAWA YASUHIKO
IPC: F02B23/00
Filed: 1979-05-02
Abstract: PURPOSE: To reduce the amount of HC contained in the exhaust gas and also to enhance the output of engine, by providing a fuel-vaporization promoting means in combustion chamber for improving combustibility of fuel.  
     CONSTITUTION: When engine temperature is low, it is detected by temperature sensor 13 and a high-voltage producing means 12 is set into operation by the sensor 13 for impressing a high voltage to high-voltage electrode 10. Resultantly, an electric field is developed between electrode 10 and piston 3, so that fuel 15 attached to the inner wall surface of recess 4 formed in piston 3 is charged negatively and collected over the surface of fuel. Since these minus charges repulse to each other in fuel particles 15, they are divided in a field where the repulsive force is strong and vaporization of fuel is promoted. Thus, fuel vaporized from the piston surface is mixed with air drawn into combustion chamber 6 and self-ignited with temperature rise caused by compression of piston 3. By thus raising the fuel vaporizing efficiency at the time when engine temperature is low, it is enabled to improve startability of engine and to shorten the time required for warming.
