An opening through which a coolant can flow into the through hole is provided on an inner peripheral side of the insulating member.

Abstract: In the present invention, when a DC reactor is in a magnetically saturated state, the on/off operations of a switching element are suspended and the switching element is set to an off state for a predetermined period of time, thereby resetting the magnetic saturation of the DC reactor and maintaining the supply of power to a load. After resetting the magnetic saturation, the pulse output of the normal pulse mode is restarted.

Abstract: A resin joint includes a joint body having a flow path, sleeves, and union nuts that fix tubes to the joint body. The joint body has a body portion with a curved inner peripheral surface and a straight portion protruding from an end portion of the body portion. The straight portion has outer and inner cylindrical portions radially arranged inside the outer cylindrical portion. An end portion of the inner cylindrical portion is positioned closer to the body portion than is an end portion of the outer cylindrical portion. A groove portion extending parallel with the outer and inner cylindrical portions in an axial direction is formed between an inner peripheral surface of the outer cylindrical portion and an outer peripheral surface of the inner cylindrical portion. The tube is fixed to the joint body such that a press-fit portion of the sleeve is press-fitted in the groove portion.

Abstract: A gasket-mounting structure includes a mounting member and a gasket. The mounting member includes a first base, an outer sleeve protruding from the first base, an inner sleeve protruding from the first base in the same direction of the outer sleeve radially inside the outer sleeve, and a groove surrounded by the first base, the outer sleeve, and the inner sleeve. The gasket includes an annular second base, an annular outer protrusion extending from the second base to be pressed in the groove, and an annular inner protrusion extending from the second base to be axially pressed on the inner sleeve radially inside the outer protrusion such that the inner sleeve is radially placed between the outer protrusion and the inner protrusion.

Abstract: A fitting body includes a tubular end whose outer periphery has an external thread and whose inner periphery has an annular groove or protrusion. A sleeve connects a tube to the tubular end of the fitting body. A union nut includes a first axial end that receives the tube therein and a second axial end to be screwed onto the external thread of the fitting body. The fitting body includes first and second regulating portions extending in directions that intersect an axial direction of the fitting body to contact the union nut being screwed onto the external thread and then sharply raise torque to be transmitted through the union nut to a hand of a worker. When being screwed onto the external thread, the union nut contacts the first regulating portion and subsequently the second regulating portion.

Abstract: An object of the present invention is to firmly fix a magnet at a predetermined position of a magnet insertion portion. A rotor for a rotary electric machine includes: a rotary shaft; at least one magnet; a rotor core having at least one magnet housing inside which the at least one magnet is attached; and at least one fixing member disposed inside the at least one magnet housing to fix the at least one magnet, wherein the at least one fixing member includes: a first fixing portion that is in contact with a side surface of the at least one magnet in a radial direction of the rotary shaft or in contact with a side surface of the at least one magnet in a circumferential direction of the rotary shaft; and a second fixing portion that is in contact with an end face of the at least one magnet in an axial direction of the rotary shaft.

Abstract: A structure for mounting a gasket on a block includes a block with a fluid channel and an annular gasket surrounding an opening of the fluid channel. The block has an annular inner wall and an annular outer wall. The annular inner wall is made of resin and located radially outside the opening of the fluid channel. The annular outer wall is made of resin and located radially outside the annular inner wall. The annular inner wall and the annular outer wall allow an axial side of the gasket to be press-fitted therebetween and are elastically deformable in their radial directions.

Abstract: A gasket includes a first slope at a first axial end. The fluid device includes a second slope that contacts the first slope. The first slope and the second slope have different gradients. The first slope allows at least the first axial end to be deformed along the second slope. The first slope contacts the second slope with a gradient that varies depending on a gradient of the second slope to seal a gap between the first slope and the second slope.

Abstract: The object of the invention is to improve operability of the process for inserting the coil conductor into the insulating member stored inside the slot of the rotor core. Each of the first insulating member and the second insulating member has one side arranged between the first coil and the second coil so that the respective sides are superposed along the radial direction of the stator core. The side of the first insulating member and the side of the second insulating member are connected with the first connection part at one end in the longitudinal direction.
