摘要:
An in-wheel motor includes a motor, a shaft, an oil pump and oil paths. The oil pump is provided on one end of the shaft. The motor includes a stator core, stator coils and a rotor. The oil pump pumps up an oil from an oil reservoir via an oil path to supply the pumped-up oil to another oil path. The another oil path supplies the oil from the oil pump to the outer periphery of the stator core of the motor from an opening end.
摘要:
A lubrication device for a toroidal type continuously variable transmission, which can set the speed change ratio continuously by transmitting a torque inputted from a power source by rolling members contacting each other through an oil film, and by varying the position of the contact portion of those rolling members steplessly, characterized by comprising: an auxiliary hydraulic power unit for generating an oil pressure without relying on said power source, a preliminary operation detector for detecting whether or not the preliminary operation relative to the start up of said power source is executed, and a preliminary lubricating mechanism for feeding the lubricating oil to the contact portion between said rolling members by means of said auxiliary hydraulic power unit before starting up said power source, when the preliminary operation is detected.

An apparatus for controlling a clutch of a motor vehicle connected to an engine and having a driving and a driven rotating member. The apparatus is capable of controlling an amount of slip of the clutch during starting of the vehicle. The apparatus includes: an engine torque determining device for determining a torque of the engine; a clutch speed monitoring device for determining whether a speed of the driven rotating member has been raised to a level substantially equal to a speed of the engine; a first slip control device for controlling the amount of slip of the clutch such that a clutch torque to be transmitted through the clutch is smaller than the engine torque by a predetermined amount, before the clutch speed monitoring device determines that the speed of the driven rotating member has been raised to the level equal to the engine speed; and a fully engaging device for fully engaging the clutch when the clutch speed monitoring device determines that the speed of the driven rotating member has been raised to the level.

Disclosed is a semiconductor device that can properly relax a stress produced by a difference in coefficient of linear expansion between an insulating substrate and a cooler and can properly remove heat by cooling of a semiconductor element. A semiconductor device comprises an insulating substrate, a semiconductor element provided on the insulating substrate, a cooler, and a porous metal plate provided between the insulating substrate and the cooler. Through holes in the porous metal plate are open at least to that surface of the porous metal plate which faces the cooler. The sectional size of the pores decreases gradually from the cooler side toward the insulating substrate side.

A method of manufacturing a heat exchanger. The method involves extrusion-molding a long fin member, which has a plurality of long fins protruding from a flat-plate-shaped long base, and cutting the long fin member by a predetermined width. The base of the fin members are also cut. This results in a heat exchanger having a plurality of fin members (10) including a plurality of fins (11) that is arranged in parallel and protrudes from a flat-plate base (12) so that slit portions are formed on both side ends in a width direction of the base (12), the fin members being arranged so that respective bases abut on each other in a frame.

A rotating electrical machine (100) is driven by a three-phase AC current and is provided with a stator core (13), a molded resin (12) for covering a coil wound on the stator core, a rotor core (40), a shaft (11) provided to the rotor core (40), a terminal base (20) provided to a coil end section, and a case (30) for covering the rotating electrical machine (100). Power cables extending from the terminal base (20) are led out of the case (30) through a case terminal box (31). A temperature sensor (22) is affixed in a hole in the molded resin (12) by the terminal base (20) and measures the temperature in the vicinity of a heat producing source.
摘要:
In a heat exchanger, fins are simply and accurately positioned in place and heat is efficiently exchanged without increasing manufacture cost, and the plurality of corrugated plate-like fins are disposed in the flow direction of a coolant in a housing. The heat exchanger has: connecting parts, which connect together the adjacent fins among the fins; protrusions ormed on the connecting parts; and positioning holes for positioning the fins formed in the housing. The adjacent fins are disposed at predetermined intervals in the coolant flow direction with a predetermined offset amount in the direction that orthogonally intersects the coolant flow direction by fitting the protrusions in the positioning holes.

An apparatus for handling a magnet handles a plurality of split magnets obtained by sequentially splitting a magnet to be split from one end thereof. The apparatus for handling a magnet is equipped with a mechanism which arranges a split magnet with respect to a previously split magnet so that the magnets are put on top of one another and the corresponding irregularities of a pair of split surfaces thereof are arranged opposite each other. The apparatus for handling a magnet is also equipped with a section where the plurality of split magnets are arranged.
