An apparatus for coupling two hydraulic transmission lines to one another is disclosed. The apparatus comprises a first coupling member and a second coupling member. The first coupling member comprises a body having first and second passages. The first passage extends from the connection to the first line to the second passage. A plug is movably positioned in the first passage for selectively opening and closing the first passage between the first line and the second passage. A first and second passage similarly extends through the second coupling member, and a plug is movably positioned in the first passage for selectively opening and closing the first passage between the second line and the second passage. The first and second coupling members are selectively joinable via a sleeve extending between the second passages thereof.

A power conversion device includes a printed circuit board, whose mounting surface is opposite to an annular surface formed by an annular stator that constitutes a motor, arranged to be separated from the annular surface with a predetermined distance, and mounted with a Hall element that detects a rotation position of a rotor of the motor on a mounting surface on a side of the stator; an inverter IC that is mounted on the mounting surface on the side of the stator of the printed circuit board to supply a high-frequency current to the stator; and an overheat detection unit that is mounted on the mounting surface on the side of the stator of the printed circuit board and detects an overheated state of the inverter IC. When the overheat detection unit detects an overheated state, the inverter IC restricts or stops a current to be supplied to the stator.

In a motor driven by a drive circuit such as an inverter, there is a problem that electric current flowing through a bearing causes electric corrosion, which impairs the durability of the bearing. A motor of the invention includes: a stator in which a winding is applied through an insulating part to a stator core formed by laminating a predetermined number of electromagnetic steel plates which have been punched into a predetermined shape; a rotor assembly in which a rotor and bearings and formed by rolling bearings are fitted to a shaft; a printed wiring board which is arranged at an end part of the stator in an axial direction and to which a drive circuit is mounted; a bracket imposed to at least the end part of the stator in the axial direction to which the printed wiring board is arranged; and a conductive sheet provided between the printed wiring board and the bracket.

摘要:
A power supply system includes a power storage module including first and second power storage units spaced by a predetermined distance from each other, and a power generating unit being capable of contacting with both of the first and second power storage units concurrently, and formed of a thermoelectric converting element; and a control unit for controlling charging and discharging of said first and second power storage units. In the first and second power storage units, different thermal reactions occur depending on whether charging or discharging operations is performed. The thermal reactions are a heat absorbing reaction and a heat generating reaction. The control unit renders one of the first and second power storage units dischargeable, and renders the other power storage unit chargeable.

An objective is to provide a motor stator that may achieve: a reduction in parts costs by shaping coil ends so that length thereof is reduced, thereby reducing the amount of use of copper, and minimizing the amount of use of binding strings for securing the coil ends in place; a reduction in manufacturing process costs by a structure which allows a protector and a wire lead outlet part to be easily assembled; and then an improvement in quality of a stator by firmly holding the coil ends and the protector. The motor stator may include a stator core 1 including slots; a plurality of cut surfaces forming flat surfaces on the outer surface of the stator core 1; end surface insulating plates 2 formed in an approximately same shape as the shape of magnetic steel plates punched out, and assembled into the stator core 1 on both axial end surfaces thereof; projections formed in a vicinity of a peripheral portion of an end surface insulating plate 2, and engaged with the cut surfaces on the stator core 1; slot-like cutouts, a little larger in size than the slots, formed on an inner peripheral side of the each end surface insulating plate 1; and coil ends. The coil ends are shaped by pressure against the end surface insulating plates 2.
