The present invention relates to sliding parts, precision parts and timepieces and electronic equipment using those parts. Sliding parts are composed by a resin in which the degree of orientation of a fibrous filler is higher at the portion serving as the sliding surface than inside the sliding part, and the fibrous filler is oriented along the sliding surface on the sliding surface. Alternatively, precision parts are composed by a resin to which has been added carbon fibers for which a carbon compound is thermally decomposed to carbon in the vapor phase and simultaneously grown directly into fibers simultaneous to this thermal decomposition. Moreover, timepieces and electronic equipment are composed by these sliding parts or these precision parts.

A thermal conductive sheet with conductive foil is obtained by press bonding a magnetic foil to a thermal conductive layer via a primer layer. Since the primer layer contains a thermal conductive filler, it has high thermal conductivity and does not interrupt thermal conduction from the thermal conductive layer to the magnetic foil. It also spontaneously destroys a skin layer on the surface of the thermal conductive layer upon the press bonding. Accordingly, the thermal conductive sheet with conductive foil of the present invention improves thermal conduction from the thermal conductive layer to the conductive foil, eliminating the unfavorable effects of the skin layer and the primer layer, and thus improves heat radiation of the thermal conductive sheet with conductive foil.

Process for forming thermal conductive sheet

An automatically mountable heat sink for effectively conducting and dissipating heat of an electronic part comprises a heat dissipation plate formed by bending a rectangular metal plate of aluminum, copper or the like by means of pressing along the lines perpendicular to its longitudinal direction and a phase changing member made of a mixture of paraffin and epoxy resin having alumina as a heat conductive filler dispersed therein and applied to a ceiling surface of the heat dissipation plate. When the heat sink and the electronic parts are soldered on a printed wiring board by heating of reflow soldering, the phase changing member made of the mixture of paraffin and epoxy resin is softened and partly moves downward by the action of gravity to abut the upper surface of the electronic part, then is solidified, thereby connecting the heat dissipation plate and the electronic part with each other.

Heat sink

A heat conductor used by being disposed between a heat sink and electronic parts mounted on a printed circuit board. The heat conductor is layered by a heat conductive layer, made of silicone gel with alumina as a heat conductive filler dispersed therein, and a potentially adhesive layer. The potentially adhesive layer consists of a hot melt layer, with alumina as a heat conductive filler dispersed therein, and a heat resistant film, to facilitate formation of the hot melt layer, adhered to the heat conductive layer on one face of the heat resistant film. The heat conductor is set on the electronic parts so that the potentially adhesive layer abuts them, and is made to adhere to the electronic parts due to heating by means of reflow soldering to reach the phase change temperature of the adhesive.

Heat conductor

A radiator member for efficiently releasing heat to the surrounding area. Cordierite powder and copper powder are mixed in a base material of dimethyl silicone. Near one surface of the radiator member the mixture ratio of copper powder is increased, while in the opposite surface the mixture ratio of cordierite powder is increased. By bringing the surface of the radiator member, containing a larger ratio of copper powder in contact with a heat generating element, heat from the heat generating element can be quickly conducted through the highly conductive copper powder. The cordierite powder, which is heated by heat transmitted through the copper powder from the heat generating element, converts the heat into far infrared rays, and then releases the rays to the atmosphere. Heat is thus efficiently released to the surrounding area.

Radiator member

A knitted or braided electromagnetic shielding material is formed by interweaving metallic or metal-clad wire rods, and each wire rod has a solder-plated layer on its surface. By heating the knitted or braided material, the wire rods are securely soldered to one another, thus preventing the knitted or braided material from loosening or disentangling, Furthermore, the contact resistance between the wire rods is reduced by the solder connections, thus enhancing the electromagnetic shielding effect of the knitted or braided material and further causing no difference in the electromagnetic shielding effect of the knitted or braided material in relation to its weaving direction. An electromagnetic shielding gasket clad with the knitted or braided material can be easily secured to a housing of electronic components, by using the solder-plated layers of the wire rods to melt the gasket thereto.

Electromagnetic shielding mesh

An electromagnetic shielding gasket attached to an end portion of a board member for contacting a desired contact portion and providing an electromagnetic shielding effect. The electromagnetic shielding gasket comprises a flat base portion linearly extending and having a width substantially equal to the thickness of the end portion of the board member. The gasket also comprises a plurality of pairs of resilient fingers arranged in an extending direction from the flat base portion. Each resilient finger transversely extends out from each side edge portion of the flat base portion. Some of the resilient fingers are bent downwardly toward one another, forming carrier strips for holding side walls of the board member therebetween. The other resilient fingers are bent downwardly or upwardly according to the position of the desired contact portion, forming resilient tabs for contacting the desired portion. The electromagnetic shielding gasket can be easily attached to the end portion of the board member using the carrier strips, and can contact any surface disposed relative to the board member using the resilient tabs.

Electromagnetic shielding gasket

An electromagnetic-shielding gasket of the present invention shields electronic components from electromagnetic waves by covering a surface of a resilient core with metal mesh and inserting the core into a joint of a conductive housing which contains electronic components. The core comprises an installing portion which is fixed to the joint of the conductive housing. A segregating portion or area separates the metal mesh from the surface of the core in the corner portions so that when the core elastically deforms greatly during insertion or use of the gasket, the metal mesh does not break as the core presses and pulls the metal mesh.
