  • Patent number: 10027012
    Abstract: A multilayer wiring plate includes a coaxial wire includes a signal line, an insulation coating and an outer peripheral conductor. An insulating layer is arranged on an inner or outer layer side. A metal film circuit is arranged by the intermediary of the insulating layer, and the metal film circuit and the outer peripheral conductor and signal line of the coaxial wire are connected. A signal line connection part that connects the signal line to the metal film circuit includes a penetration hole A that passes through the insulating layer and the outer peripheral conductor; the coaxial wire from which the outer peripheral conductor is removed inside the penetration hole A; a hole filling resin filled inside the penetration hole A; a penetration hole B that passes through the hole filling resin and the signal line; and a plated layer arranged on an inner wall of the penetration hole B.

  • Patent number: 9966164
    Abstract: The present invention provides an insulated coated wire comprising a wire, a wire coating layer disposed around the wire, and a wire adhesive layer disposed around the wire coating layer, wherein the wire coating layer is of one type of or a combination of two or more types of a fluorine resin, a polyamide-imide resin and a low dielectric polyimide resin having a relative permittivity of less than 3.6 at 10 GHz, and a multi-wire wiring board using the insulated coated wire.

  • Patent number: 9668345
    Abstract: A multilayer wiring board includes a first metal foil wiring layer that has at least two or more layers of metal foil wiring lines and is arranged on a mounting surface side for mounting a surface mount type component, a wire wiring layer that is arranged on an opposite side of the mounting surface, and in which an insulation coating wire is wired, and a first interlayer conduction hole that has a conduction part which electrically connects the metal foil wiring line positioned on a surface of the first metal foil wiring layer to at least one of the metal foil wiring line in an inner layer of the first metal foil wiring layer and the insulation coating wire of the wire wiring layer. A hole diameter of the first interlayer conduction hole varies in a board thickness direction of the multilayer wiring board.

  • Patent number: 6634820
    Abstract: The present invention provides a printer system that performs a printing operation on recording sheets of various types. In accordance with the present invention, the image of a recording sheet on which recording sheet identification information for identifying the type of the recording sheet and data identification information for identifying the type of print data is printed in advance is picked up by an image pick-up device. From the picked up image, the recording sheet identification information and the data identification information are extracted and then compared so as to detect inconsistency between the type of the recording sheet and the type of the data. By this printing system, a data printing operation can be performed on desired recording sheets.

  • Patent number: 6252351
    Abstract: A contact layer having a low resistance in an LED is extended from an inside edge of a light take-out region in a light emitting dot to a central position thereof, whereby an input current in the light take-out region expands, while an electrode is extended from an inside edge of the light take-out region to the center of the light take-out region so as to shape like substantially a letter T with a length which is not over the center, whereby increase in an electrode covering ratio in the light take-out region can be suppressed. As a result, a uniform light output in the light take-out region can be attained, so that a light output can be remarkably improved.
