Abstract: A piping device of the present invention includes an oil supply path, a narrower path connected with the oil supply path and having an inside diameter smaller than that of the oil supply path, an air space into which the oil is discharged from the narrower path, a wall defining the air space having a recess, and a plurality of branch paths into which the oil having impinged on the recess flows, wherein a vertex of the recess and an end of the narrower path face each other. This configuration makes it possible to suppress the uneven distribution of a flow rate of oil discharged into the air space. Furthermore, since the vertex of the recess and the end of the narrower path face each other, the discharged flow in which the uneven distribution of the oil flow rate is suppressed can be diverted with respect to the vertex of the recess as the center of the diversion. Thus, it is possible to allow flow rates of oil flowing into the respective branch paths to be substantially uniform with a simple configuration.

Abstract: An illuminated button including a key button and an electroluminescent light (EL) for illuminating the key button from its bottom. The key button is composed of a silicone rubber material mixed with white color particles which prevent, while the EL is inoperative, a pink light reflected from the EL from being projected to the outside through the key button. This makes possible to solve a problem of a conventional illuminated button, which includes a key button and a white light EL used as a backlight, in that the pink color of the EL is seen from the outside through the key button, and this spoils the beauty of the illuminated button.

Abstract: Stress exerted on a liquid crystal display element via a case was likely to impede display on the liquid crystal display element, or damage a liquid crystal display device. A front end of a rib 9 protruding toward a case 1 from a peripheral edge portion of a holder 8 supporting a liquid crystal display element 4 is brought into contact with the case 1, whereby stress on the case 1 is imposed on the rib 9. Thus, stress directly acting on the liquid crystal display element 4 via a rubber sheet 7 can be prevented.

Abstract: A lighted switch illuminator which solves a problem of a conventional device in that it was difficult to reduce its thickness and size because the electroluminescent (EL) layer functioning as an illuminator is adhered to a separate film click board. An EL layer is directly formed on a film click board by stacking its layers (consisting of a transparent electrode layer, a light emitting layer, a dielectric layer, a rear electrode layer and an insulation layer) in order excluding hollow convex portions of the film click board. Upper contacts and lower contacts are formed on the film click board and a printed board, respectively, such that they face each other. Depressing a key button pushes the corresponding hollow convex portion so that the upper contact and the corresponding lower contact are brought into conduction, in which case a good clicking feeling is obtained because the EL layer is not formed on the back of the hollow convex portions.
