A magnet splitting device includes a one-side holder for holding a plurality of pre-split magnets on one sides of respective splitting grooves, an other-side holder for holding the magnets on the other sides, and an actuating unit for causing relative movement of the other-side holder to split the magnets all at once. The other-side holder includes a plurality of other-side independent holding parts for holding the magnets independently. The actuating unit includes a plurality of independent actuating parts for moving the other-side independent holding parts independently and a simultaneous operating part for simultaneously operating the holding parts.

A coil sub-assy includes a coil plate which has an insulating film attached to at least one side thereof and an “I”-shaped portion to be inserted into a slot of a stator core. The plurality of coil plates forming coils of an identical phase are laminated in a thickness direction of the “I”-shaped portion. The coil plates opposite to each other are formed such that a shortest distance between end faces of the “I”-shaped portions in a width direction is longer than a shortest distance between end faces of the “I”-shaped portions in the thickness direction.

A toroidal continuously variable transmission in which a rolling member is arranged between a pair of rotary members with contacting its outer circumferential face with a rolling face of those rotary members being opposed to each other through an oil film, and in which a holding member for holding the rolling member in a rotatable condition is provided includes a lubricating oil feeding hole for spraying lubricating oil to a plurality of portions at the center side of the rotation of at least one of the end faces of the rolling member in an axial direction, which is arranged on the holding member.
摘要:
A toroidal type continuously variable transmission, in which an input disc and an output disc are arranged on the common axis with being opposed to each other in the rotatable condition, and in which the rolling member is arranged between the input disc and the output disc, so as to transmit a torque between said input disc and said output disc through said rolling member, by applying the clamping force to said input disc and said output disc in said axial direction, characterized by comprising a clamping force controller for controlling the clamping force to be applied to said input disc and said output disc based on a physical quantity relevant to heat stress of said rolling member.
摘要:
A toroidal type continuously variable transmission; in which a rolling member for mediating the transmission of a torque is clamped between at least a pair of rotary members; and in which a clamping force for clamping the rolling member in the direction not to let the rolling member be released from between the rotary members is applied to the rolling member, comprises: a detector for detecting temperature rise of either, a temperature of a rolling face of the rotary members for clamping the rolling member, or a temperature of the rolling member; and a rolling member controller for reducing the clamping force in case a temperature rise is detected by said detector.

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 formed 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.

A heat exchanger is provided with a cooling fin including a plurality of fin portions and a base portion supporting the fin portions, and a plurality of pins press-fitted into the fin portions. In the heat exchanger the pins each having a wider width than each space between the fin portions formed in advance in parallel straight shapes are press-fitted into the spaces in a direction from a top end of each fin portion toward the base portion. Accordingly, the fin portions are formed into corrugated shapes by plastic deformation, thereby fixing the pins between the fin portions in positions apart from the base portion. In each space the pins are arranged at intervals in a longitudinal direction of each space. The pins arranged in adjacent spaces are placed with a displacement in alternating pattern.

A method of manufacturing a heat exchanger is disclosed. The heat exchanger comprises a plurality of fin members including a plurality of fins that is arranged in parallel and protrudes from a flat-plate base so that slit portions are formed on both side ends in a width direction of the base, the fin members being arranged so that respective bases abut on each other in a frame. Specifically, the method comprises: an extrusion molding operation of extrusion-molding a long fin member; a fin cutting operation of cutting the long fin member having just been extrusion-molded to cut the long fin member by a predetermined width; and a base cutting operation of cutting a long base in a long-fin cutting region made in the fin cutting operation so that slit portions are formed.

A cooling fin includes fin parts integrally extending from a base part. Each fin part is partially formed at a slant so that a proximal end portion is straight and a distal end portion is wavy (corrugated). Each fin part is partially slanted to make each fin part wavier as coming closer to the distal end portion from the proximal end portion. In a manufacturing process of the cooling fin, firstly, a straight cooling fin is produced by extrusion molding (an extruding step). Subsequently, the distal end portion of each fin is partially bent in a direction intersecting an extruding direction into a wave shape (a bending step).
