Abstract:
A method of making a multi-level micro-wire structure includes imprinting first micro-channels in a curable first layer over a substrate, curing the first layer, and locating and curing a curable conductive ink in the first micro-channels to form first micro-wires. Multi-level second micro-channels are imprinted in a curable second layer in contact with the first layer with a multi-level stamp, the second layer is cured, and a curable conductive ink is located and cured in the multi-level second micro-channels to form multi-level second micro-wires. At least one of the multi-level second micro-channels contacts at least one first micro-wire. A multi-level second micro-wire in at least one of the multi-level second micro-channels is in electrical contact with at least one first micro-wire.

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.
Abstract:
An imprinted optical micro-channel structure for transmitting light to an optical receiver or receiving light from an optical transmitter includes a substrate and a cured optical layer formed in relation to the substrate. The cured optical layer includes one or more optical micro-channels imprinted in the cured optical layer. Each optical micro-channel includes a cured light-transparent material forming a light-pipe that transmits light in the optical micro-channel. The optical transmitter is located in alignment with a light-pipe for transmitting light through the light-pipe or the optical receiver is located in alignment with a light-pipe for receiving light from the light-pipe.
Abstract:
An imaging unit at a tip end portion of an insertion section has a board on which the image pickup device is installed, a cable through which a signal is input to and output from the board, and a ground bar which is provided so as to protrude from the surface of the board and is connected to a ground of the board. In a distal portion of the cable on the imaging unit side, a shield part is connected to the ground of the board through the ground bar and a core line is directly assembled on the board. The ground bar supports the cable on the board such that the height of the cable in the vicinity of a board-mounting portion of the cable becomes greater than or equal to a predetermined value.
