A compact, thinned and water-tightened combined switch, is structured by a single switch comprising a front sheet having a domed projection which can be reversed to the back side and is provided at the back side with an electrode, an electric circuit body having an electric contact to contact with the electrode and a domed convex portion provided in the vicinity of the center of the domed projection. In operation process, firstly the projection is reversed and an electrode provided near the periphery of the convex portion contacts with the electric contact on the electric circuit body and secondly an electrode provided in the vicinity of the center of the domed convex portion contacts with the electric contact on the electric circuit body.

A liquefied paper material is used as raw materials. A paper frame member 1 supporting a vibrating plate is paper-skimmed and formed. On paper-skimming and forming, a central hole for use in voice coils, air-release hole 1a releasing air pressure in a rear of the vibrating plate to outside due to vibration of the vibrating plate. A loudspeaker system is manufactured using the paper frame member 1.

A wiring substrate includes a wiring substrate body and a stiffener. The latter is formed from a rolled metallic sheet and is bonded to a first main surface of the wiring substrate body. The stiffener has a boundary profile, in a plan view, which is substantially identical to that of the wiring substrate body, and a first direction of the boundary profile of the stiffener or the wiring substrate body intersects the rolling direction of the stiffener at an angle. This construction reduces the amount of deformation of the wiring substrate produced by bonding of the stiffener to the wiring substrate body and/or caused by temperature variations experienced by the construction. Because of this reduction in deformation, the wiring substrate provides improved reliability with respect to connections made to an electronic component mounted thereon as well as improved reliability with respect to connections made to another printed wiring board.

A ceramic-metal composite assembly includes an intermediate member made of a material having a thermal expansion efficiency between those of the materials forming a ceramic member and a metallic shaft member. The intermediate member is metallurgically joined to the ceramic member whilst being mechanically joined to the metallic member to constitute a single unit.

A rotatable member (40) such as a sprocket is rotatably mounted on a fixed shaft member (32), and a first oil passage (72) extending in a radial direction is formed by a thrust member (36) abutting an axial end surface of the rotating member. The inner end of the first oil passage communicates with a radial bearing interface (A) of the rotatable member, and an oil jet ejected from an orifice (68) of an oil nozzle (66) is directed to an open outer end of the first lubricating oil passage. Because the first oil passage is fixed in position, the radial bearing interface receives an adequate supply of lubricating oil fed from the oil nozzle. The other axial end of the rotating member may be provided with a second lubricating oil passage (82) which also extends in a radial direction, the second lubricating oil passage having an open outer end and an open inner end communicating with the radial bearing interface. The centrifugal force acting on the lubricating oil in the second lubricating oil passage promotes a favorable re-circulation of the lubricating oil, and hence a favorable lubrication.

A device for loading and unloading a tape cassette includes a cam disc rotatably supported to a chassis and at least one guide route disposed thereon and extending from near the rotating axis of the cam disc to the periphery thereof so as to be topologically shifted in the rotating direction, and a swinging arm pivoted to the chassis and having a cam follow pin received in the guide route. The tape cassette is transported together with the cassette holder from an inlet port to the tape deck and vice versa. A shift member is adapted to retractively guide the cassette holder by cooperating with the swinging arm.
