Patent number: 11972877Abstract: A superconducting wire connector includes superconducting wires and a sintered body containing MgB2. The superconducting wires are connected by the sintered body. At least one of the superconducting wires includes a superconducting core having a first outer surface. The sintered body is in contact with the first outer surface. A method of connecting superconducting wires by a sintered body containing MgB2 includes exposing a superconducting core of at least one of the superconducting wires by removing a portion, positioned in the middle in a longitudinal direction of the at least one of the superconducting wires, of a metal sheath disposed around the superconducting core, disposing the at least one of the superconducting wires through a container, filling the container with a raw material of MgB2, and forming the sintered body being in contact with an outer surface of the superconducting core by sintering the raw material filled in the container.Type: GrantFiled: February 26, 2021Date of Patent: April 30, 2024Assignee: HITACHI, LTD.Inventors: Shinji Fujita, Tsuyoshi Wakuda, Yota Ichiki, Motomune Kodama

Patent number: 9872378Abstract: There are provided an electronic element mounting board and an electronic device capable of suppressing transmission of incident light to an electronic device through a circumferential edge part of an opening of a board and thus of reducing a noise level in receiving an image. An electronic element mounting board includes an insulating substrate. The insulating substrate has an opening and a lower surface, and an electronic element is disposed on the lower surface so as to overlap the opening in a plan view. A circumferential edge part of the opening of the insulating substrate has a porosity lower than a porosity of a portion outside the circumferential edge part. Since it is possible to suppress transmission of incident light to the electronic element through the circumferential edge part, it is possible to reduce a noise level in receiving an image in the electronic element.Type: GrantFiled: April 28, 2014Date of Patent: January 16, 2018Assignee: KYOCERA CORPORATIONInventors: Shuya Kubo, Kouki Suda, Tsuyoshi Ishimabushi, Shinji Ichiki, Yousuke Moriyama

Patent number: 9608020Abstract: An imaging element mounting substrate includes: an insulating base comprising insulating layers, the insulating base surface comprising an opening which is located at a center thereof; a connection electrode disposed at a lower surface of the insulating base around the opening; and light-transmission control layers between the insulating layers, and comprising inner edges located on an outside of the opening. An inner edge of one light-transmission control layer lies closer to the opening than an inner edge of another light-transmission control layer as seen in a transparent plan view, and the insulating base has, in an inner periphery of the opening of an insulating layer constituting a lower surface of the insulating base, an inclined portion which is inclined such that the opening becomes smaller in size from the lower surface as approaching an upper surface of the insulating base.Type: GrantFiled: October 20, 2014Date of Patent: March 28, 2017Assignee: Kyocera CorporationInventors: Shinji Ichiki, Yousuke Moriyama
