摘要:
A net-shape molded heat sink is provided which includes a thermally conductive main body and a number of thermally conductive fins integrally connected to and emanating from the main body. The heat sink is formed by overmolding a carbon-carbon matrix core plate with a thermally conductive polymer composition that is filled with thermally conductive filler material. The molded heat sink is freely convecting through the part which makes it more efficient and has an optimal thermal configuration.

The present invention is directed to a golf ball comprising a soft core and a hard cover to produce a golf ball having a reduced spin rate. The present invention is also directed to an improved golf ball comprising at least one interior layer and/or a core comprising a silicone material. It is preferred to also utilize a multi-layer cover in conjunction with the silicone materials. The golf ball of the present invention may also utilize an enlarged diameter which serves to further reduce spin rate. The resulting golf ball exhibits properties of reduced spin without sacrificing durability, playability and resilience.

The present invention provides a method of manufacturing a vehicle cup holder arm, and a vehicle cup holder assembly produced thereby. The method includes injection molding a first material to form a base including an attachment feature adapted for engagement within an aperture adjacent a cup holder opening in a vehicle. A second material is injection molded to form an arm cup around the base and includes an arm. The second material does not chemically bond to the first material so that the arm cup and arm are rotatable with respect to the base for adjustably securing a cup in the cup holder opening. A third material is injection molded onto the arm to form a soft rubber grip for engaging a cup. The cup holder arm may be movable vertically for adjustment with respect to differently-sized cups.

A method of manufacturing a net-shape moldable U-shaped heat sink assembly includes injection molding a thermally conductive polymer composite material. The method includes forming a heat sink assembly base member with a number of integrated fins members thereon. A right upstanding wall extends from a first side of the base member and a left upstanding wall extends from a second side of the base member to form a substantially U-shaped heat sink assembly. To enhance thermal conductivity, fins members may be integrally formed into the base member, right wall and/or left wall during the molding of the heat sink assembly. Also, a flexible metallic substrate or hinges may be embedded within the U-shaped heat sink assembly to permit positioning of the right wall and left wall relative to the base member for custom configuration of the heat sink assembly.

A roller. Grooves are recessed on an outer peripheral surface of an outer race in a bearing. A part of a synthetic resin tire is integrally adhered to the outer race of the bearing and is inserted and bonded within at least one of the grooves on the outer peripheral surface of the outer race in the bearing, so that firm adhesion or bonding can be obtained. Accordingly, such an adhered fitting body is prevented from being peeled off from the outer race of the bearing and the tire and the outer race of the bearing are prevented from separately detaching even when the bearing is exposed to a heavy load or rotates at a high speed.

A method and apparatus for encapsulating microelectronic devices. In one embodiment, a microelectronic device is engaged with a support member having a first edge, a second edge opposite the first edge, and an engaging surface with at least a portion of the engaging surface spaced apart from the first and second edges. The first edge of the support member is positioned proximate to a wall of a mold and an aligning member is moved relative to the wall of the mold to contact the engaging surface of the support member and bias the first edge of the support member against the wall of the mold. The microelectronic device is then encapsulated by disposing an encapsulating material in the mold adjacent to the microelectronic device. By biasing the first edge of the support member against the wall of the mold, the method can prevent encapsulating material from passing between the first edge of the support member and the wall of the mold, where the encapsulating material would otherwise form flash. Accordingly, a method and apparatus in accordance with an embodiment of the invention can reduce or eliminate flash adjacent to the first edge of the support member.

A vent apparatus includes a tank mount made of a weldable plastics material and a fuel systems component such as a valve assembly. The valve assembly includes a valve housing made of a non-weldable plastics material and a valve movable in a valve chamber formed in the valve housing to open and close an aperture leading to a venting outlet. The tank mount supports the valve housing in a position in a mounting aperture formed in a fuel tank. The valve housing is made by injecting non-weldable plastics material into a mold containing the pre-molded tank mount.

A jointed linkage support system is provided with joints that allow movement and bending in many directions and degrees of freedom. A chain-like linkage system made up of a series of joints is molded in a single step from materials having different melting temperatures in a series of alternating communicating mold cavities. The jointed linkage support system emerges from the mold fully assembled. An electrical switch may be provided within.one of the joints between sleeves and rods whereby movement of the rod relative to the sleeve actuates the switch.

The invention relates to a method for fabricating a decorative laminate panel, wherein the decorative laminate panel includes a decorative laminate layer and a core. The method is achieved by forming a decorative laminate of a predetermined size, placing the decorative laminate within a die cavity, injection molding the core within the die cavity while the decorative laminate remains within the die cavity to form a decorative laminate panel and releasing the formed decorative laminate panel from the die cavity. The invention further relates to a decorative laminate panel manufactured in accordance with the method defined above and a unitary edge profile member adapted for use in the fabrication of a compound injection molded decorative laminate panel.

A method for producing a golf ball including a spherical elastic inner layer having a large number of projections with a round shape or a polygonal shape when viewed two-dimensionally on the outer surface with a predetermined space, and a thermoplastic resin outer layer covering the inner layer. The method employs a mold including an upper mold and a lower mold with a spherical cavity formed in the inside and a parting surface provided at a position corresponding to an equator of the spherical cavity, with pole sections of the upper mold and the lower mold each provided with a plurality of columnar support pins elongating into the cavity reciprocally movably. In the method, the inner layer is supported at the cavity center portion of the mold by the support pins from above and below at the outer surface space position, and an external layer resin is injected into the space between the inner layer and the cavity wall surface so as to integrally form the inner and outer layers.
