Title: Mixing valve
Inventor: KOJIMA TADASHI
IPC: F16K11/044
Filed: 1980-12-27
Abstract: PURPOSE: To control the valve position by installing in the acutator an electromagnetic pressure transporting device, which transfers the fluid forcibly into a pressure chamber, and a responsively moved body, which moves in response to the fluid pressure in the pressure chamber.  
     CONSTITUTION: Upon receiving an operation signal from a control circuit, an electromagnetic pressure transporting device 22, transfers the fluid forcibly from No.1 chamber 25 into No.2 chamber 26. The fluid, then returns to No.1 chamber through a passage 30. The pressure in No.2 chamber 26 is raised to a predetermined value during the circulation described above. The pressure is determined by the flow rate of fluid that is transferred forcibly into No.2 chamber 26 by means of the electromagnetic pressure transporting device 22 and the degree of resistance given to the fluid by an orifice 31. In response to this pressure, the position of a responsive moving body 27, that is, the position of the valve body; is determined.

Title: Braking force controller for vehicle
Inventor: YAMAMOTO YASUNORI
IPC: B60T8/00
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To drive a hydraulic pump in proper timing so as to suppress an uncomfortable feeling of a driver accompanying a response delay in a brake assist device or an unnecessary hydraulic pump action by starting an action of an oil pressure source when a value related to a brake pedal actuating speed is the predetermined value or more. SOLUTION: In case of an emergency, a controller 40 opens a pressure increasing valve 22 on the basis of a signal from a master cylinder pressure sensor 44 and actuates a driving motor 27 for a pump 28 while a pressure reducing valve 25 is closed, so that brake fluid is supplied to a wheel cylinder 7 for a wheel 4 via a pressure increasing line 26 and a brake system 6. The controller 40 determines whether a current master cylinder pressure increasing speed is higher than a predetermined speed or not, and then, determines whether a braking action is carried out against an emergency or not. In the case of a braking action in an ordinary traveling time in which an actuating speed is low, the motor 27 is not operated, so that waste of power and generation of vibration and noise can be reduced.

Title: Backstop
Inventor: INOUE MASAHIRO
IPC: B61H9/04
Filed: 1987-07-30
Abstract: PURPOSE:To prevent reverse rotation by interposing an engaging member comprising a turning claw and the like between an axle and a wheel and inserting and extracting an operating rod in and from an axial cavity provided on the axle to put the turning claw in an operating position and a non-operating position in a backstop for wheels of a trolley or the like. CONSTITUTION:When a rod 6 is set in a cavity 2 of an axle 1 in such a manner that a small-diameter portion 6e and a taper portion 6d are positioned on the left side of a guide hole 1a, an anchor 3 is projected from the guide hole 1a to a position opposite to the forward end surface 5c of a turning claw 5 to check reverse rotation of a wheel 4. When the wheel 4 is rotated normally, the turning claw 5 is pushed in the direction of releasing the projection to a void portion H by the anchor 3 to be rotated in a body with the wheel 4. When the rod 6 is extracted from the cavity 2 and the small-diameter portion 6e and the taper portion 6d are positioned opposite to the guide hole 1a, the anchor 3 enters the guide hole 1a, whereby backstop for the wheel 4 is released. Thus, reverse rotation can be prevented to improve safety.
