Title: Method for determining vehicle rollover
Inventor: MOMOHARA SHIGERO
IPC: B60R21/20
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To increase the accuracy of determining whether or not there is a possibility of vehicle rollover according to the roll angle and roll angular velocity of the vehicle. SOLUTION: A threshold line S, which is set on a two-dimensional map whose parameters are the roll angle θ and roll angular velocity ω of the vehicle, consists of a slanted part and a horizontal part, with the slanted part indicating a rollover area. Since there is no possibility of vehicle rollover unless the roll angle θof the vehicle exceeds a full bump roll angle θFB, an area on the side of an original point beyond a line of θ=±θFB is set as a non-rollover area, so that when rollover does not occur because of a decrease in roll angle θbefore the roll angle θ increases and reaches the full bump roll angle θFB, the hysteresis lines H9 and H10 do not cross the threshold line S from the non-rollover area to the rollover area.  Thus, errors in the determination as to whether or not there is a possibility of vehicle rollover are prevented and the accuracy of the determination can be increased.

Title: Rotary electric component with push-switch
Inventor: MIYAKE TOSHIKATSU
IPC: H01H25/06
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a rotary electric component that has little play in the rotary direction of the operating shaft, and is inexpensive and easy to assemble. SOLUTION: In the rotary electric component with a push-switch, the operating shaft 4 has a collar portion 4b radially projecting from an outer periphery. Because this collar potion 4b and a rotary body 3 has been in a spline joint, a distance from the rotary center C1 to the position where the collar 4b engages with a projection 3d is longer in comparison with the past. In consequence of this, the rotary play of the projection 3d becomes smaller than the past even if it has a little play in the fitting state, so the rotation of the operating shaft 4 is directly transmitted to the rotary body 3.
