A manufacturing method for a connector housing to which an elongated metal terminal is connected may include injecting molten resin into a mold so as to form the connector housing. The mold may include a first projection configured to form an inlet for the metal terminal and a second projection configured to form a terminal connection space communicating with the inlet, the second projection being movable relative to the first projection. A diameter of a tip end of the second projection may be larger than a diameter of a tip end of the first projection and a recess in which the tip end of the first projection is inserted may be provided in an end face of the second projection.

A rotor includes a yoke that is formed annularly and a resin magnet integrated with the yoke. The yoke includes a first inner circumferential surface, a second inner circumferential surface, and a third inner circumferential surface. The second inner circumferential surface is adjacent to the first inner circumferential surface, and has a radius larger than a radius of the first inner circumferential surface. The third inner circumferential surface is adjacent to the second inner circumferential surface, and has a radius larger than both of the radius of the first inner circumferential surface and the radius of the second inner circumferential surface.

A rechargeable battery includes a battery case, a cover that closes an open end of the battery case, and a power collection terminal arranged on the cover to supply power from a power generating element to an external terminal. The power collection terminal extends through a gasket arranged on a lower surface of the cover, an insulator arranged on an upper surface of the cover, and the external terminal arranged on an upper surface of the insulator. An annular sealing member is held between the lower surface of the cover and the gasket. The insulator is a resin-molded component. The insulator includes a through hole defined by an inner wall that includes a lower open end, an upper open end, and a central portion. At least one of the lower open end and the upper open end has a larger diameter than the central portion.

A control device of an injection apparatus outputs a control command to a hydraulic pressure device to perform injection by supplying hydraulic fluid to the back of an injection piston 15 from an accumulator 25 and, at this time, to execute speed control for controlling the speed of the plunger by an opening degree of an injection control valve. Further, the control device outputs a control command to the hydraulic pressure device to perform boosting by opening a booster valve to supply hydraulic fluid to the back of the booster piston and pressurizing the hydraulic fluid behind the injection piston by the booster piston and, at this time, to execute pressure control for controlling the pressure of the molding material by an opening degree of the injection control valve. Further, the control device can start outputting a control command for pressure control after start of outputting a control command for opening the booster valve in transition from injection to boosting.

The present disclosure relates generally to seal rings useful in oil-lubricated systems such as automobile transmissions, torque converters and automatic clutches. In one embodiment, the disclosure provides an injection molded seal ring comprising a circular ring body extending between a first end and a second end engageable with the first end, the circular ring body including an inner circumferential face; an outer circumferential face; a first lateral face; a second lateral face opposing the first lateral face; a recess formed in the outer circumferential face, the recess not extending to both the first lateral edge and the second lateral edge of the outer circumferential face; and an injection molding gate vestige disposed in the recess, the injection molding gate vestige not extending beyond the outer circumferential face.

A resin filling method for a magnet embedded core includes: a fixing step of sandwiching the laminated iron core at axial ends thereof between a first mold and a second mold provided to face each other; and a resin injecting step of injecting a resin into the magnet insertion hole from a resin injecting portion provided in the first mold or the second mold, wherein in the resin injecting step, an end portion of the resin injecting portion is inserted into the magnet insertion hole beyond an axial end surface of the permanent magnet inserted in the magnet insertion hole.

A biocompatible and/or food-safe tube assembly (1) is used to connect at least three tube connectors (A, B, C). A first tube section (2) serves to connect two (A, B) of the at least three tube connectors (A, B, C). A sec-ond tube section (3) opens into the first tube section (2) via an orifice (4) in a casing wall (5) of the first tube section (2). An orifice sealing body (8) delimits the orifice (4) to the inner lumen of the first tube section (2) and to the inner lumen of the second tube section (3). The first tube sec-tion 2 and the second tube section 3 are molded onto the orifice sealing body 8. A core (10) is used for this purpose. The result is a biocompatible and/or food-safe tube assembly that avoids manufacturing problems.
