Title: Control valve of fluid pressure controller
Inventor: NAGASE HISAO
IPC: B60T8/46
Filed: 1993-04-28
Abstract: PURPOSE:To eliminate remaining pressure while the valve is not being operated after its operation completely without degrading control feeling. CONSTITUTION:Compressed air is fed to an inlet chamber from a brake valve at the time of ordinary braking, fed to a brake booster through a normally open type opening/closing valve 24 for holding and an outlet chamber 22 to operate a brake. When the brake is released, compressed air in the brake booster is discharged to the atmosphere through the outlet chamber 22, the normally open type opening/closing valve 21 for holding and the inlet chamber 21 to release the brake. With this constitution, the opening/closing valve 24 for holding is normally open, so the compressed air in the brake booster is discharged completely without remaining pressure. When input pressure is introduced into a designated pressure chamber 28 at the time of ABS control, a stepped piston 32 travels to the right, and a valve element 33 is placed onto a valve seat 9c. It is thus possible to close the opening/closing valve 24 for holding, and shut off the inlet chamber 21 and the outlet chamber 22, and thereafter the compressed air in the inlet chamber 21 is not fed to the brake booster afterwards.

Title: Variable frequency multivibrator circuit
Inventor: TAKEHARA SHIGERU
IPC: H03K3/282
Filed: 1989-04-25
Abstract: PURPOSE: To improve the linearity of an output frequency by constituting the circuit of two transistors, provided with emitter terminals connected to both the terminals of a timing capacitor and two feedback circuits. CONSTITUTION: As a timing capacitor C is charged, a transistor 40 starts conducting, and a transistor 42 starts to be cut off. When the transistor 40 starts conducting, a transistor 46 starts cutting off through a transistor 50. Therefore, a voltage at the base of a transistor 54 increases and fed back positively to the base of the transistor 40. As the transistor 42 is cut off, a potential at the emitter of a transistor 52 increases, and additional base drive is supplied through an AC coupling capacitor 78 to the transistor 40. Thus, the linearity of the output frequency can be improved with respect to a control current.
