IPC: B62D7/15
Filed: 1988-08-30
Abstract: PURPOSE:To get rid of any influence of backlash by installing a dead zone control means, which increases a wheel steering angle in proportion to car speed if a valve gets starting, between an input shaft interlocking with a steering wheel and a differen tial control valve for hydraulic pressure of a rear-wheel steering actuator.

This spool 126 is connected to a drive shaft 24 and a cylinder member 21, and it is engaged with a control member 20 fitted in an output shaft 19 of a front-wheel steering mechanism 30. This control member 20 is engaged with a control lever 18 being operated by an actuator D, and in this actuator D, its oil quantity is the fewer, the speedier by adjustment of an oil regulating valve E being controlled by a dead zone control means (consisting of a current subtraction converter 45 or the like) being decreased in propor tion as growing larger in car speed, whereby the control lever 18 works and the control member 20 separates from the cylinder member 21. Therefore a wheel steering angle at the outset of operation of the differential control valve B becomes larger. According ly, highly accurate steering angle control is securable with such a simple mechanism that is not affected by backlash.

Title: Follow-up control device for vehicle
Inventor: SETO YOJI
IPC: B60K31/04
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To avoid car speed limiting state with braking force by setting the preset car speed of a follow-up control means to the low speed side threshold by a car speed setting means when the control start is instructed in the case where the own car speed detected by a car speed detecting means is a low speed side threshold or lower. SOLUTION: When an own vehicle is put in stop or low-speed running state and a set switch is turned on to start follow-up control, a set car speed is set to a low speed side threshold V1 where can be kept without braking force. Then, in the state where a preceding vehicle is not captured, when the own car speed Vs is equal to or lower than a low speed side threshold V1, the acceleration maximum value aMAX is limited to a small first preset value a1 (S43). When the car speed V exceeds the lower speed side threshold V1, the acceleration maximum value aMAX is set to a second larger preset value az 2 (S44). Accordingly, enough accelerating condition can be attained. Further, when a preceding vehicle is detected, the acceleration maximum value aMAX is set to a third largest preset value a3 (S45). Thus, the acceleration condition according to the preceding vehicle can be attained.

Abstract: PURPOSE:To enable the large decrease in defect of an insulation film obtained at the final step by a method wherein an insulation film formed on a semiconductor substrate is heat-treated by implanting ions in a specific amount or more, and a conductive layer is formed thereon. CONSTITUTION:On the P type semiconductor substrate 21 made of an Si crystal having a surface orientation of (100) and a specific resistance of 0.02OMEGAcm, the insulation film 22 made of Si oxide is formed to a thickness of 300Angstrom  by the treatment of thermal oxidation e.g. in a dry oxygen atmosphere having a temperature of 950 deg.C.

Then, the heat treatment to the insulation film is carried out for 10min in a nitrogen atmosphere having a temperature of 1,000 deg.C, resulting in the formation of a conductive layer 24 into a required pattern. In this manufacture, if the quantity of ion implantation to the insulation film is over 1X10<14>pcs/ cm<2>, with this value as the limitation, the defect contained by the insulation film largely decreases from a value of 12pcs/cm<2> that can be negligible in practical use.
