Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a control circuit which controls leakage currents in a low-voltage CMOS circuit and, at the same time, can selectively reduce the leakage currents. SOLUTION: A leakage current control circuit 16A is provided with a reference current circuit 118 which is integrated in a semiconductor area and works as a current source, a low-pass current-to-voltage converter 114 which works as a bias circuit, and a testing element 116 which is composed of an MOS transistor.

Abstract: PROBLEM TO BE SOLVED: To prevent a winch main body from being projected in the inside of an engine room even by impact at the time of collision by supporting a winch frame to which a winch main body is mounted, by means of a pivot and a shear pin to a place close to the front end part of a body frame. SOLUTION: When the bumper and the like of a vehicle running in the opposite direction from the head is hit against a front downward inclined part 4T formed at the front end part of a winch frame 4, clockwise impact around a pivot 5 is applied to the winch frame 4, itself. By this constitution, a shear pin 6 comparatively low in strength is sheared off first, the winch frame 4 together with a winch main body 3 mounted onto the winch frame keep rotating around the pivot 5 until the back face of the winch frame 4 is brought into contact with the back face of a side member 7. Thus as mentioned above, since the whole of the winch frame 4 is so rotated as to creep into an area beneath a body frame, the winch main body will never be projected afterward in a vehicle, and thereby the engine room will never be damaged.
