Abstract: A millimeter wave reception device includes a base member, an antenna portion placed on an upper surface of the base member, and a cover arranged above the antenna portion to cover the antenna portion. The antenna portion is arranged within a space formed by the upper surface of the base member and an inner surface of the cover. The cover is formed in a tapered shape, and includes not less than one inclined surface having a constant gradient such that the space becomes narrower at a position closer to an upper portion. An angle formed between the inclined surface of the cover and the upper surface of the base member is not less than 60° and not more than 90°.

Abstract: A feed horn structure in which a feed horn and a horn cap can be combined and, a manufacturing method thereof. A converter having that feed horn structure, and a satellite communication receiving antenna can be obtained. The feed horn structure of a satellite communication receiving converter includes a cylindrical feed horn receiving a radio wave from an antenna portion and guiding the radio wave, and a horn cap fixed to the feed horn so as to surround one end of the feed horn at antenna side. The feed horn and the horn cap are integrated by integral molding.

Abstract: A method for fabricating a molded resinous part with a metal distributed in a surface thereof comprising: kneading a low-melting metal and a resin having a curing temperature lower than a solidification point of the low-melting metal in a molten state; and injection-molding the resulting kneaded mixture into a mold whose temperature is set to a temperature equal to or lower than the solidification point of the low-melting metal and higher than the curing temperature of the resin, thereby obtaining a molded resinous part comprising the resin as a core and the low-melting metal in a surface thereof.

Abstract: A feed horn structure in which a feed horn and a horn cap can be combined without generating whitening, crack and the like, a manufacturing method thereof, a converter having that feed horn structure, and a satellite communication receiving antenna can be obtained. The feed horn structure of a satellite communication receiving converter includes a cylindrical feed horn receiving a radio wave from an antenna portion and guiding the radio wave, and a horn cap fixed to the feed horn so as to surround one end of the feed horn at antenna side.

Abstract: A tubular resin member constituting the frame of a feed horn is divided into an inner side resin member located at an inner circumferential plane side and an outer side resin member located at an outer circumferential plane side. The inner side resin member is formed of a resin material that allows metal plating. Metal plating is applied on the inner circumferential plane of the inner side resin member to form a metal plate layer corresponding to a waveguide plane. The outer side resin member is formed of a resin material containing a coating composition to improve the aesthetic appearance. Accordingly, a feed horn of a satellite communication reception converter that can be fabricated readily and economically can be provided.

Abstract: A converter main body is formed from composite material wherein reinforcing material comprising carbon fiber is combined with plastic material comprising ABS resin in an amount that is 30 wt % thereof. The coefficient of linear expansion of that composite material is made to be less than or equal to the coefficient of linear expansion of aluminum die cast alloy.

Abstract: A rectangular switch body has a plurality of terminals of round flexible wire rods and is provided at its four outer side surfaces with engagement members. Various kinds of cross-sectionally C-shaped brackets of a resilient metal plate provided with engagement members are prepared. An insert mount having a mount frame with at least three side walls engageable with at least three side surfaces of the switch body and engagement members is prepared. By using one of the brackets or the insert mount, the switch body is mounted on a printing wiring board in a desired direction or on a panel.

Abstract: Herein disclosed is a small-sized switch of the type, in which a clip-shaped moving contact made coactive with a knob is selectively and simultaneously brought, by operating the knob, into sliding contact with both the outer sides of at least two of a plurality of fixed contacts arranged in the bottom of a switch body, thus effecting the switch changing operations. The small-sized switch has its plural fixed contacts made of a round wire.
