Abstract: A power generation device converts vibrational energy into electric power using a vibrational power generation element in which an electret is provided on one substrate of substrates configured to be relatively movable while maintaining a mutually facing state, and supplies the electric power. A vibrational power generation element has the same configuration as the vibrational power generation element and converts vibrational energy into electric power. The vibrational power generation element is connected to a light-emitting diode via a bridge-type full wave rectifier circuit constituted by diodes, a smoothing circuit constituted by a capacitor, and a light-emitting diode drive circuit. A power generation state of the power generation device using the vibrational power generation element and the like is displayed by blinking of the light-emitting diode.

Abstract: A switch and a relay include a contact with a smooth contacting surface. A side surface of a fixed contact faces a side surface of a movable contact. The fixed contact has an insulating layer and a base layer stacked on a fixed contact substrate, and a first conductive layer formed thereon through electrolytic plating. The side surface of the first conductive layer that faces the movable contact becomes the fixed contact (contacting surface). The movable contact has an insulating layer and a base layer stacked on the movable contact substrate, and a movable contact formed thereon through electrolytic plating. A side surface of a second conductive layer that faces the fixed contact becomes the movable contact (contacting surface). The fixed contact and the movable contact have surfaces that contact the side surfaces of the mold portion when growing the first and second conductive layers through electrolytic plating.

Abstract: A light guide includes a core made of material having translucency and an optical path conversion mirror for reflecting the signal light from the optical element and converting the optical path of the signal light formed on at least the core. The signal light is transmitted through the core by the reflection at the optical path conversion mirror. The optical path conversion mirror surface has an inclination angle ? formed with a bottom surface of the core changing in the X-direction in a cross-sectional shape in which the core is cut at a YZ plane, the Y-direction being an optical axis direction of the optical element, the Z-direction being an advancing direction of the signal light of the light guide, and the X-direction being a direction perpendicular to both the Y-direction and the Z-direction.

Abstract: A switch has a first contact portion in which a plurality of conductive layers is stacked on an upper side of a first substrate, and a second contact portion in which a plurality of conductive layers is stacked on an upper side of a second substrate. Respective end faces of the conductive layers at the first contact portion are contacts of the first contact portion. Respective end faces of the conductive layers at the second contact portion are contacts of the second contact portion. Each contact of the first contact portion and each contact of the second contact portion are faced to each other so that the contacts come into contact with or separate from each other.

Abstract: An organic device has a substrate made of polymer, and a polymer layer adhered on the substrate. A crystallization degree of an adhesive surface with the polymer layer in the substrate is smaller than a crystallization degree of an interior of the substrate. In a manufacturing method for manufacturing an organic device including a substrate made of polymer; and having a polymer layer adhered on the substrate, the manufacturing method includes performing a low crystallization process on an adhesive surface with the polymer layer in the substrate to have a crystallization degree lower than a crystallization degree of an interior of the substrate.

Abstract: An oxide film is formed on an end surface of a waveguide which includes an under cladding, a core and a over cladding. An end surface of a fiber guide holding an optical fiber is coupled the end surface of the waveguide formed the oxide film with a glue. It is preferable that the oxide film is SiOx (1?x?1.5). This oxide film has a composition ratio of an oxygen atom smaller than the stable composition, and thus it is easy for OH radicals to appear on the surface of the oxide film. Such OH radicals bond chemically with the resin of the waveguide and the glue. Thus, an adhesive strength between the waveguide and the fiber guide is improved.
