  • Publication number: 20230004243
    Abstract: A manufacturing method of the present disclosure is a method for manufacturing a wiring body. The manufacturing method includes a growth process, a transfer process, and a peeling process. In the growth process, a conductive layer of a wiring body is grown on a catalyst provided on a pattern plate.

  • Patent number: 8164014
    Abstract: A concavo-convex light emitting section provided on an under surface of a base material is formed of a synthetic resin with inorganic oxide dispersed therein. A larger amount of light is reflected by inorganic oxide having a large refractive index and dispersed inside the synthetic resin, to cause a plurality of light emitting sections to emit bright light with a small number of light emitting elements. A light guiding sheet capable of making bright and uniform illumination and a movable contact body using the same are realized with a simple configuration.

  • Patent number: 8164015
    Abstract: A movable contact unit includes a light-guide sheet, a cover sheet, a movable contact, and a light-transmissive light-guide portion. The light-guide sheet includes a film-shaped substrate, and a convex and concave luminescent portion provided on the substrate. The cover sheet faces the substrate. A dome-shaped resilient movable contact made of a thin metal sheet is attached to the cover sheet at a position corresponding to the luminescent portion. The light-guide portion is provided on the cover sheet at a position other than an area where the movable contact is disposed or on the light-guide sheet at a position other than an area where the light-guide portion is disposed. If the light-guide portion is provided on the light-guide sheet, the movable contact may be attached to the light-guide sheet without using the cover sheet.

  • Patent number: 8097821
    Abstract: The movable contact unit with a light-guiding function has the following structure. An uneven section is formed in a section that is to be lighted on the lower surface of a TPU base sheet. A film with a refractive index of light lower than that of the base sheet is disposed beneath the lower surface of the base sheet in a manner that the uneven section is embedded in the film. Besides, an adhesive layer is disposed beneath the film so as to hold a movable contact. The movable contact unit structured above is effectively employed for a lighted panel switch capable of reducing loss in amount of light and providing the section that is to be lighted with required illuminance.

  • Publication number: 20110315534
    Abstract: A light guide sheet guides light emitted from a light introducer. The light guide sheet includes a film-shaped substrate, a light emitting section formed on the substrate, and a belt-shaped light-blocking section. The light emitting section reflects or scatters light transmitting in the substrate to the outside. The light-blocking section is formed in the substrate by coloring a position of the substrate to a color. In the position, the light emitting section is not formed. The color absorbs the light which is emitted from the light introducer. The light emitting section can alternatively be composed of a plurality of projections and/or a plurality of recesses. Such a light-blocking section is formed in a position of the substrate where the projections and/or the recesses are not formed.

  • Patent number: 8025435
    Abstract: A light guide sheet and a movable contact element using the single sheet have a simple structure and can be variously illuminated. The light guide sheet includes irregular-shaped light extracting elements formed on a film-like base material; and light-transmissive, belt-shaped light guide parts each connecting a predetermined number of groups of the light extracting elements. In addition, dome-shaped movable contacts formed of a conductive sheet metal are arranged on the bottom surfaces of the light extracting elements.

  • Patent number: 7946720
    Abstract: A light shielding part includes a slit provided between a first light guide body and a second light guide body, and an attenuation part which has unevenness formed by print and is additionally provided near end sides of the first light guide body and the second light guide body. The light shielding part can prevent light from being transmitted between the first light guide body and the second light guide body. With this configuration, when illumination parts of the first and second light guide bodies are illuminated, it is possible to illuminate the illumination parts of the first and second light guide bodies at different timings without the illumination part of one light guide body being illuminated with light leaked from the other light guide body.
