Abstract:
An endoscope distal end portion includes: a channel that is tubular, the channel being where a surgical tool is to be inserted in; a light guide configured to guide illumination light emitted from a light source; an imager configured to capture an image of an observed region illuminated with the illumination light from the light guide; and a fixing member that is made of resin and that has a columnar outer shape, the fixing member being configured to seal around the channel, the light guide, and the imager, wherein the channel is in contact with the imager, and the light guide is in contact with at least one of the channel and the imager, and a contact surface of the channel in contact with the light guide or a contact surface of the imager in contact with the light guide has a groove or a projection formed thereon.
Abstract:
A stacked mounting structure and a method of manufacturing stacked mounting structure are provided. The stacked mounting structure includes a plurality of members provided with a mounting area which is necessary for installing and operating components to be mounted on at least one principal surface, and an area for connections for signal transfer for operating the components to be mounted, and an electroconductive member which is disposed on the area for connections between the mutually facing members, and a cross section of the electroconductive member is same as or smaller than the area for connections, and an end portion of the electroconductive member is extended from a principal surface of one member up to a principal surface of the other member, and a height of the electroconductive member regulates a distance of the mounting area.
Abstract:
A structure includes a substrate on a surface of which a functional element and a first electrode are disposed, wherein the functional element provides a predetermined function by an operation based on an electrical signal and the first electrode is coupled to the functional element; an insulating member in a thin film that covers the surface of the substrate and extends from an end of the substrate; and a second electrode disposed on a substrate-side surface of the extending portion, which is extending from the end of the substrate, of the insulating member, wherein the second electrode is coupled to the first electrode. The second electrode is electrically coupled to a coaxial cable.
