Title: Rear wheel steering device for vehicle
Inventor: HIRUTA HIDEJI
IPC: B62D7/15
Filed: 1987-07-15
Abstract: PURPOSE:To ease the tight corner braking phenomenon by providing a compensating means which compensates the steered ratio characteristics of a rear wheel steering means that when a center differential sharing the driving force to rear and front wheels is detected for the locked state, the steered ratio characteristics of a rear wheel steering means is made in the phase reverse to that at the time when the center differential is detected to be released from the locked state. CONSTITUTION:When a vehicle runs, the running speed V, the steering wheel angle signal thetaH, and the detected signals of a center differential operation detecting sensor 101 are sent to a control unit 100. Said unit 100 sets the target wheel steered ratio of front wheels on the basis of the specified wheel steered ratio of the front wheels. Thus the unit 100 controls and drives a stepping motor 40 to run a steered ratio control mechanism 18, which controls the steered ratio between both rear and front wheels to the target ratio. In such case the control unit 100 is designed that when said sensor 101 detects the locked state of a center differential 62, the steered ratio characteristics is compensated to have it in the phase reverse to that when the center differential is free. Thereby the trace difference between the inner front and the inner rear wheel may be minimized to zero when the vehicle is swerved.

Abstract: PURPOSE: To improve the toughness by making one kind or over of filler aggregates and preforms in contact with a molten parent metal pool, embeding them with a grown oxide reaction product between the molten parent metal and an oxidant and extracting them from the molten parent metal.  
     CONSTITUTION: A preform 19 is kept in a container 13 and floated on the surface of a molten parent metal group 15 consisting of Al or Si or the like. A thin layer 17 made of a material that controls reaction between a surrounding oxidant atmosphere and the molten parent metal is used to cover a surface of the molten parent metal pool and the preform 19 exposed to the surrounding oxidant atmosphere. The thin layer 17 prevents the atmosphere from being in contact with the preform 19 to allow the oxidation reaction product to grow in the preform 19 and to be partially embeded. Then, the preform 19 is extracted from the parent metal molten pool 15 to produce self-supporting ceramic matrix and composite bodies.
