Abstract: An electrical connector 10 disposed on a circuit board 1 covered by an electrically conductive cover 70, the connector comprising an electrically conductive tubular outer conductor 11 mounted on the circuit board 1 and extending axially along the direction of mating Z with a counterpart electrical connector 20, 40, and an electrically conductive supporting portion 14 provided in the outer conductor 11 and having a connection portion at the top in the direction of mating Z, wherein the connection portion of the supporting portion 14 and the cover 70 are brought into direct or indirect contact when the circuit board 1 is covered by the cover 70, thereby electrically connecting the electrical connector 10 and the cover 70.

Abstract: To provide an electrical connector assembly capable of reliably restricting the tilting of an adaptor connected to a connector to a predetermined angle or less, an electrical connector assembly includes a first connector, an adaptor, a tubular portion forming part of the adaptor with a supporting portion made of a rigid material, a plurality of resilient pieces, and engagement portions protruding radially outwardly from the distal end portions of the resilient pieces. The first connector involves a main body portion having an opening the main body portion has a peripheral wall forming a recess portion; and, when the adaptor is tilted a predetermined angle relative to the first connector while the adaptor is engaged in a mated state, the supporting portion restricts further tilting of the adaptor by abutting the peripheral wall.

Abstract: A motor includes inner-peripheral and outer-peripheral rotors which rotate coaxially and have permanent magnets along a circumference of each rotor; and a phase varying device for relatively rotating the rotors so as to vary a relative phase therebetween. The device has a forward-angle working chamber for relatively rotating the inner-peripheral rotor forward with respect to the outer-peripheral rotor, by using pressure of supplied working fluid; a backward-angle working chamber for relatively rotating the inner-peripheral rotor backward with respect to the outer-peripheral rotor, by using pressure of supplied working fluid; a passage switching valve for performing distribution with respect to supply and drainage of the working fluid between the working chambers in accordance with the position of a spur; and an electromagnetic pressure control valve for controlling pressure of the working fluid, and for controlling the position of the spur in the passage switching valve based on the controlled pressure.
