    摘要: A connector means includes a connector housing provided with a plurality of bores which is defined by a pair of plastic bases each having a plurality of hemicycle grooves each of which has an inner diameter 1 to several .mu.m larger than an outer diameter of each of the optical cables to be connected. After the optical fibres are inserted into the respective bores and secured therein, one end surface of the connector housing is polished. A pair of connected housings are retained so that the polished end surfaces abut on each other thereby to attain a connection between a plurality of optical cables.

    摘要: A method of and an apparatus for molding a plastic wherein the injection pressure (transfer pressure) is switched to a holding pressure when the internal pressure of the mold cavity sensed by a pressure sensor reaches a predetermined injection pressure (transfer pressure), to initiate holding of the pressure applied to the cavity. The holding pressure is removed when the internal pressure thereof becomes zero or in accordance with the detection of a predetermined inflection point in the internal pressure which is indicative of a gate sealing point in the mold cavity or is brought to a predetermined value close to zero. The molded articles are of high precision finishes, and conservation of energy and natural resources can be achieved.

    摘要: A cooling device for cooling semiconductor elements by removing heat generated from the semiconductor elements such as, for example, semiconductor integrated chips in a large-sized electronic computer. The cooling device is fashioned of a composite AlN-BN sintered material having a Vickers hardness not higher than one-fifth of that of an AlN material, and an anisotropic property of thermal conductivity in a two dimensional direction is higher than that of AlN which is isotropic in thermal conductivity. The cooling device may be mass-produced while nevertheless having a high transfer performance matching the quantity of heat generated for each semiconductor element even if the composite sintered material is uniform in shape and size. The composite sintered material is formed by a mixture of a hexagonal BN powder having an average particle diameter of not less than 1 .mu.m and an AlN powder having an average particle diameter of about 2 .mu.m, with a sintering aid being added and the powdery mixture being subjected to a hot press sintering whereby the sintered material is low in thermal conductivity in a direction parallel to an axis of a shaft of the hot press.
