Abstract: A nozzle for injection molding is made of at thermally conductive metal material but is thermally conductively blocked or interrupted. An abrupt reduction in wall thickness and/or a gap in the continuity of thermally conductive material occur along the nozzle material passageway. This provides a localized restriction to thermal conduction, causing a reduction in heat flow from the mold to the material supply while cooling the melt material near the end of the nozzle. This material, which is relatively cooled to near the mold temperature, becomes the last injected material when filling of the mold is completed, occupying the area of the sprue. As a result, the sprue is relatively cool, thus reducing stringing and shortening mold cycle time.

The flow control pin has a head with a complementary geometry with that of the melt channel at a flow control surface. The flow control pin is raised and lowered by an actuation mechanism to constrict or release the flow of the melt stream independent from the movement of the valve pin.

Abstract: A connector is mounted on a printed circuit board in an enclosure. A member is interposed between the enclosure and the printed circuit board so as to hold the printed circuit board on the enclosure. The member allows change in the attitude of the printed circuit board relative to the enclosure. When the connector is coupled to the other connector, the connector receives a force from the other connector in the electronic apparatus. The force induces the change in the attitude of the connector and the printed circuit board. The change in the attitude in this manner enables consumption of the energy of the force within the member. Generation of stress can be suppressed in a bonding member such as a solder coupling the connector with the printed circuit board, for example. Generation of cracks can be prevented in the solder. Shockproof is improved for the connector.
