Abstract: A rotary connector for electrically connecting a set of headphones to a portable personal audio device to help prevent stress on the electrical wires of the set of headphones. The rotary connector includes a substantially hemispherical jack socket defining a substantially hemispherical jack space. The outer surface of the jack socket has an annular primary contact therearound. The inner surface of the jack socket has a secondary and tertiary contacts. A resiliently deflectable top cup defines an upper space and has an interior surface with an annular first contact therearound. The top cup has an axial extent outwardly extending from the exterior surface of the top cup with an axial bore extending between the interior and exterior surfaces of the top cup. A generally spherical plug has an outwardly extending axial shaft which inserted into the axial bore of the top cup.

Abstract: A motor comprises a rotary shaft, an oil impregnated sintered bearing rotatably supporting the rotary shaft, a bearing holder supporting the oil impregnated sintered bearing and a motor case. A lateral pressure device is provided to the rotary shaft which abrasively contacts the rotary shaft from a radial direction and provides a lateral pressure so that the rotary shaft is displaced in the radial direction. The lateral pressure device further comprises an inner ring made of an oil impregnated sintered member in which a through-hole abrasively contacts the rotary shaft from the radial direction is formed, an elastic member which provides a lateral pressure so that the rotary shaft is displaced in the radial direction and an outer ring which holds the elastic member and is fixed to the motor case.

Abstract: An eccentric-motion motor for driving a utilization mechanism includes a stator defining a closed surface pathway, an armature composed of a permanent magnet rollably disposed on the closed surface pathway, a series of electromagnetic elements disposed in the stator along the closed surface pathway, circuitry for successively energizing the electromagnetic elements to cause them to attract and/or repel the armature so that it rolls along the closed surface pathway, and a coupler mechanism for coupling the armature to the utilization mechanism so that as the armature is caused to roll, the utilization mechanism is powered by the operation of the motor.

Abstract: An engine control device comprises generation current detecting means for detecting generation current of the generator, current value fluctuation removing means for removing the fluctuation of the output of the generation current detecting means, and correction quantity calculating means for calculating the correction quantity of intake gas into said engine in accordance with the output of the current fluctuation removing means.

Abstract: A circuit breaker comprises a static switch electrically connected in series with a disconnecting switch having an operating mechanism with a handle to close and open a system of main contacts. A voltage sensor ocmprises an electromagnet with a moving core capable of occupying an active locking position and an inactive unlocking position of the mechanism, respectively in the on state and in the off state of the switch. Opening of the disconnecting switch is inhibited if voltage is present on the output terminals.
