Title: Power cable
Inventor: WATANABE KAZUO
IPC: H01B7/18
Filed: 1994-10-05
Abstract: PURPOSE: To increase transmission current, prevent deviation in the circumferencial direction of a wire, and prevent infiltration of water between wires by filling a filler into apertures between wires constituting a wire shield layer and reducing thermal esistance in the radial direction of the cable. CONSTITUTION: A filler 10 is filled between wires 6a and a cushion layer 5 and a wire presser layer 7 are both contacted with the filler 10 so that thermal resistance between the cushion layer 5 and the wire presser layer 7 is drastically reduced compared with that in the case of intervening air between them. Therefore, transmission current can increase more than the conventional one. When the transmission current is the same as the conventional one, the size of the electric cable can be reduced. The filler 10 is filled in apertures between wires 6a so that deviation of the wire 6a in the circumferencial direction is prevented, buckling resistance of the cable is improved, and infiltration of water between the wires can be prevented.

Abstract: PURPOSE:To prevent fly-out of a brush and to eliminate an assembling step after the brushes are associated by providing a protrusion projecting in a direction perpendicular to a brush energizing direction, and providing a stopper to be engaged with the protrusion when the brush is moved, at a brush guide. CONSTITUTION:A protrusion 17a projecting in a direction substantially perpendicular to the energizing direction of a brush 17 sliding in contact with a flat commutator 3, i.e., radially outward of a housing 21, is formed at the brush 17, and a stopper 18a to be engaged with the protrusion 17a is formed at a brush guide 18 containing the brush 17. Accordingly, when the brush 17 is moved along the guide 18 to the commutator 3 side, the protrusion 17a is engaged with the stopper 18a to prevent the brush 17 from flying out from the guide 18. Thus, in assembling steps of component members, the guide 18 and the brush 17 can be assembled in a sub-assembly state before they are assembled in a motor, and hence removal of dusts, operation of the brush before assembling can be confirmed.

Abstract: PURPOSE:To check the current flow on the secondary side and to prevent semiconductor switches from being damaged, by giving DC bias in the predetermined direction to the voltage applicable to the secondary side of a transformer when the current on the secondary side of a transformer exceeds a specified value. CONSTITUTION:When the DC portion is contained in the power voltage across AC side terminals 3a and 3b, a transformer 2 is excited in DC to increase the current on the secondary side. When the current on the secondary side of the transformer 2 detected by the transformer 2 exceeds a specified value, a comparison circuit 26 outputs a positive bias signal. An addition circuit 27 adds this bias signal to an AC signal from a pattern generation circuit 22 and modulates it in pulse width with a pulse width modulation circuit 24 to control a rectification bridge drive circuit 25. The increase by the DC components of the current on the secondary side can thereby be checked.
