Title: Vehicle posture control system
Inventor: OKAZAKI HARUKI
IPC: B60T8/24
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle posture control system capable of performing a posture control on an ad hoc basis according to the operating skill of a driver. SOLUTION: An SCS.ECU10 estimates that the operating skill of a driver is relatively large when the averaged value of a yaw rate deviation with the lapse of time, which is a deviation between a target yaw rate set according to the running condition of a vehicle and an actual yaw rate measured actually on the vehicle, is smaller than a specified first reference value. It corrects a yaw rate control start threshold or side slip angle control start threshold in the increasing direction, and the initial correction amount for yaw rate control or side slip angle control in the decreasing direction so as to increase the freedom degree of steering of the driver. Thus, while maintaining a running stability, a proper SCS control can be performed according to the operating skill or psychology of the driver.

Abstract: PROBLEM TO BE SOLVED: To prevent a cover member from being unwillingly opened or closed, with the use of a spring member and a cam member, when the cover member is opened or closed through the intermediary of a hinge device to and from a body of a portable computer or the like. SOLUTION: When a second hinge member 11 having a cam part 11a is closed to a first hinge part 10 incorporated with a spring member 10A, a first and a second convex curved peripheral surface part 10a, 10b of the spring member 10A are made into resilient contact with a first and a second convex curved peripheral part 11d, 11e of the cam part 11a. Accordingly, a resilient force acts in an opposite direction with r2 which is larger than an eccentric distance from the center axis O so that a torque is exerted to the cam part 11a in the direction F1. Thus, the a strong closing force is exerted to the second hinge member 11.  When the second hinge member 11 is opened in the direction F1, the second and the first convex curved surface parts 10b, 10a are made into resilient contact with the first and the second concave curved surface parts 11d, 11e through the opening motion of the cam part 11. Thus, a torque is exerted to the second hinge member 11 in a direction reverse to the direction F1, and accordingly, a strong opening force is effected.

Abstract: PROBLEM TO BE SOLVED: To reduce the cost concerning a picture processing function, to relax power consideration and to make design compact by transferring obtained data, unit to a synthetic output when whole numerals agree with reference which is fixed by means of a threshold value. SOLUTION: Threshold value comparing mechanisms 50 and 51 compare the numerals 24 and 25 of a counter from a data input with the previously fixed threshold values 41 and 42 of a system. When a value exceeds the threshold value in the counter, it is judged that the proper threshold value exceeds a line 43 or 45 and change occurs in the state of control logic in accordance with it. This means that a device for storing data which exceeds the threshold value is provided with data to be used for a merging operation. Then, control logic 66 monitors the condition of threshold value excess signals 43 and 45 and an event state 52. When a correct condition is satisfied, control logic expresses a merging enable signal 47 so as to enable executing a data merging operation.
