Title: Brake hydraulic pressure regulating valve
Inventor: FUJITA NORIYUKI
IPC: B60T8/28
Filed: 1987-06-30
Abstract: PURPOSE:To prevent transmission of an abruptly increased pressure to a wheel cylinder and to aim at stabilizing the performance of a brake hydraulic pressure regulating valve by disposing a spring between a disc member and a piston which are provided in an outlet chamber so as to urge the disc member toward the wheel cylinder but to urge the piston toward an inlet chamber. CONSTITUTION:When the hydraulic pressure of a master cylinder is abruptly increased due to a rapid brake operation or the like, brake oil flows into an outlet chamber 18 from an inlet chamber through a communication hole 19 so as to abruptly increase the pressure in the outlet chamber 18. However since a wheel cylinder connection part 14 is blocked by a disc member 24, hydraulic pressure is fed into a wheel cylinder only through a liquid passage 26, and therefore no abrupt pressure increase occurs in the cylinder. Even though the pressure is greatly increased, the outer periphery of the disc member 24 s flexed so as to further constrict the passage 26, and accordingly, it is possible to surely prevent the pressure of the cylinder from being increased. Further, upon release of brake a coil spring returns a piston 16 to its original position, thereby it is possible to prevent the performance of the brake hydraulic pressure regulating valve from being unstable even though the brake operation is continued.

     CONSTITUTION: In the state of no excitation, an N-pole side end of a permanent magnet 6 is contacted with an end surface 3a of a core 1 by the magnetic flux of the permanent magent 6. When the core is so excited that the part of the core 1 corresponding to the N-pole of the permanent magnet 6 becomes to N-pole and the part of the core 1 corresponding to the S-pole of the permanent magnet 6 becomes to S-pole, the N-pole side end of the permanent magnet 6 is repelled from the core 1 and then an end of a soft iron 5 coupled to the N-pole side end of the permanent magnet by a coupling member 7 is attracted to the core 1, thereby allowing the reverse action thereof. When the excitation is removed, the N-pole side end of the permanent magnet 6 is caused to contact with the end surface 3a of the core 1 again by the magnetic flux of the permanent magnet 6.

Abstract: PURPOSE: To make it possible to obtain high-accuracy voltage-converted output, by allowing capacitor-charged voltage to be discharged for a fixed period of time matching number of revolution and transferring a value at the time of the discharge to another capacitor.  
     CONSTITUTION: Two pickup coils are provided on both ends in diametral direction of a revolution voltage distributor of an ignition device to obtain signals with phase difference by 180° as demonstrated by (A) and (B) in the sketch. A pulse-shaped voltage, (C) fixed to a constant voltage by a Zener diode ZD at t=t 2  and a resistance R 1 , is charged to a capacitor C 1  through a diode D to obtain a voltage V 0 .  When transistors Q 1  and Q 4  are turned on and off at t=t 0  (position signal 1) and  also the transistors Q 1  and Q 4  are turned on and off at t=t 1  (position signal 2), a  voltage V c1  of the capacitor C 1  is discharged (D) by a time interval between the  position signals 1 and 2 from V 0 . By transferring this voltage to a capacitor C 2   through an operation amplifier OP 1  and an FET, a voltage value inversely proportional to number of revolution is obtained.
