In order to prevent any erroneous insertion of a thin circuit boardinto a gapformed between a main circuit boardand a connectorwhen the thin circuit boardis inserted into an inserting portformed at the connectorfixed at a mounting surface of the main circuit boardby electric connection, a guideis formed by applying solder onto the mounting surface of the main circuit boardand in the vicinity of the inserting port. The guidecan prevent any insertion of the thin circuit boardinto the gap

Electric equipment

An actuator, a vehicle mounted radar device, and an automobile drive control system that employ a non-contact type potentiometer to detect a rotation angle of a rotary shaft. The non-contact type potentiometer includes a pair of planar magnets disposed opposite and parallel with respect to each other on a U-shaped magnetic yoke, the polarities of the magnets being arranged such that approximately parallel magnetic fields are formed around a magnetic detection element that is retained on a support shaft connected to a rotary shaft on an actuator, and can freely rotate relative to the stationary member. By rotating the rotary shaft on the actuator, a change in the output from the magnetic detection element occurs, thus allowing a rotation angle of the rotary shaft to be detected.

Non-contact type potentiometer, actuator, vehicle mounted radar device, and automobile drive control system

A brushless motor includes a stationary member; a rotating member rotatably supported with respect to the stationary member; a stator provided in the stationary member and provided with a stator coil for generating current magnetic field under an exciting state; and a rotor magnet provided in the rotating member for obtaining a revolutionary power due to an electromagnetic mutual effect with the current magnet field of the stator coil. The rotor magnet is formed such that segment-shaped magnets are placed annularly with predetermined gaps circumferentially. The gaps are filled with a magnetic resin material.
