Abstract: An end face of a transparent electrode or a backside electrode of an EL element is not bared at an end surface of an outer periphery of an EL insert molding or an end surface of an inner periphery of a through hole portion. A decorative film covers a front side of an EL element and molding resin is injected onto a backside surface of the EL element to form a molding resin portion. An end potion of the decorative film is bent to cover the end portion of the EL element and extends beyond the end portion of the EL element a distance larger than at least a thickness of the EL element.

Abstract: A surface of a substrate which is an outer packaging case is integrated with a decorative film and an EL device. An upper case of the outer packaging case has through-holes through which a transparent electrode layer and a back electrode layer that constitute the EL device are exposed. Contact pins are elastically contacted with the transparent electrode layer and the back electrode layer via the through-holes, and the electrodes are thereby connected to an EL-driving circuit.

Abstract: A shaped plastic magnet comprising a shaped body obtained by molding a mixture of an SmFeN magnetic powder with a resin binder into a desired shape, where the surface of the shaped body is subjected to a coating treatment using a phosphate. Preferably, the coating treatment is performed by using a paint containing a phosphate. The shaped plastic magnet may be used as a rotor to be incorporated in motors. The product is highly resistant against corrosion, and provides extended life to motor rotors and the like.

Abstract: A light illuminating type switch with a good click rate and having a desired click characteristic near to that of a single member of a metal dome. Fixed contacts 7a are provided on a base sheet 7. On an upper side of the base sheet 7, a dome shaped movable contact 8 capable of electrically connecting the fixed contacts 7a on the base sheet by being elastically deformed is arranged. The surface of the dome shaped movable contact 8 is attached with a flexible EL sheet E by using adhering agents 9a and 9b via an insulating member 6 over a peripheral portion of the dome shaped movable contact 8. The EL sheet E is formed with cut portions 10 partially at positions along an outer peripheral edge of the dome shaped movable contact 8. At least a pair of the cut portions 10 are formed at symmetrical positions centering on the movable contact 8.

Abstract: A manufacturing method of an EL insert molding which can manufacture the EL element without damage while a temperature and a pressure of resin to be injected are maintained at an optimum forming condition. A luminous portion and a non-luminous portion are provided in an EL element. The EL element is inserted in a cavity of an injection die, and resin is injected into the cavity to manufacture the EL insert molding. In the cavity, a gate portion is provided at a position opposite to the non-luminous portion of the EL element. A decorative film 2 may be formed integrally in front of the EL element.

Abstract: An end face of a transparent electrode or a backside electrode of an EL element is not bared in an end surface of an outer periphery of an EL insert molding or an end surface of an inner periphery of a through hole portion and the end face of the transparent electrode or the backside electrode of the EL element does not short-circuit with arranged other members. A decorative film is provided on a surface side, an EL element 3 provided on a backside of the decorative film, and molding resin is injected onto a backside surface of the EL element to form a molding resin portion. An end potion of the decorative film is provided to be shifted outwardly than an end portion of the EL element. The end portion of the EL element is covered with the end portion of the decorative film in a manner that the end portion of the decorative film is bent in a projection molding of the molding resin.

Abstract: To remove the danger of breaking electrodes, to stabilize the quality of the device, and to facilitate the connection of the device to an EL-driving circuit. The surface of a substrate, outer packaging case 1 is integrated with a decorative film A and an EL device B. The upper case 1a of the outer packaging case 1 has through-holes 10 through which the transparent electrode layer 5 and the back electrode layer 8 that constitute the EL device B are partly exposed out. Contact pins 13 are elastically contacted with the transparent electrode layer 5 and the back electrode layer 8 via the through-holes 10, and the electrodes are thereby connected to an EL-driving circuit.

Abstract: A unitized light illuminating type switch in a thinned type and having enhanced click feeling. A movable contact and an electroluminescent sheet are formed in an integrated structure by attachedly pasting together the movable contact and the electroluminescent sheet. Fixed contacts are provided on a switch sheet. A movable contact capable of electrically connecting to the switch sheet by being elastically deformed is arranged above the switch sheet. A flexible electroluminescent sheet A is attachedly pasted to a surface of the movable contact by interposing an insulating member as far as a peripheral portion of the movable contact other than the movable contact.
