Title: Rear wheel steering gear for vehicle
Inventor: OMURA HIROSHI
IPC: B62D7/14
Filed: 1989-04-25
Abstract: PURPOSE:To improve controllability as well as safety at the time of failure in a backward running detecting means by steering rear wheels on the basis of a steering ratio set as an opposite phase at the time of backward running or low speed running and as an in phase at the time of high speed running. CONSTITUTION:At the time of backward running of a vehicle or the specified speed or less, the control by a first steering control means 101 is inhibited by the second steering control means 102 of a control unit U that receives a signal from a speed sensor 31 (36) and a reverse switch 42. Accordingly, even if the backward running signals are constantly outputted due to the failure of the reverse switch 42, the rear wheel steering at the time of backward running is controlled according to the speed, on the basis of a steering ratio set as an opposite phase at the time of low speed running and as an in phase at the time of high speed running, and the steering ratio thereby becomes the in-phase when the speed is increased, thus ensuring running stability.

Filed: 1989-04-28
Abstract: PURPOSE:To act an optical trigger switching circuit like a zero cross or a non-zero cross by providing a function change means so as to adjust the luminous quantity of the irradiating light. CONSTITUTION:A PNPN element 3 and a photo transistor(TR) 14 are irradiated simultaneously with a light beams 1 being a trigger from one and same light source.
