Abstract: A high frequency heating power device for an implanted device comprises a switch circuit, an input/output circuit, a high-frequency signal generating circuit, and a check circuit. When a high frequency output circuit applies a high frequency measuring voltage between a guide wire and the body ground board, a voltage is detected which corresponds to the impedance of a circuit which is made up of lead wires, the guide wire, the patient's body, and the body grounding board. It is determined by a discriminating circuit whether or not the voltage thus detected is in a predetermined allowable voltage range. The operator is informed of the discrimination by means of a display circuit and a buzzer circuit, so that he can determine the position of the end of the guide wire with respect to the end of the catheter with ease.

Abstract: A steering device is disclosed. It has a steering shaft which is designed to rotate together with the steering wheel. A fixed member fixed to the car body is provided to surround the steering shaft. A stationary member is also provided to surround the steering shaft. A rotary member is rotatably supported by the steering wheel for traveling around the periphery of the fixed member. It also has a timing belt wound around the peripheries of the fixed member, stationary member and rotary member for operatively connecting them.
