Title: Semiconductor integrated circuit device and fabrication thereof
Inventor: OTSUKA FUMIO
IPC: H01L29/786
Filed: 1994-10-28
Abstract: PURPOSE: To prevent fluctuation of threshold voltage due to fluctuation of potential at the channel part of an MISFET by forming a silicon layer on a superconduction substrate and a plurality of MISFETs on the silicon layer. CONSTITUTION: A silicon oxide 2 is deposited by about 100Å on a superconducting substrate 1 having perovskite structure of Nb or Y-Ba-Cu-O system. The silicon oxide 2 serves as a tunneling film of quasi-particle for bringing about a superconducting state. A plurality of MISFETs are formed on the silicon oxide 2. With such structure, even if the potential at the channel part of an NMOSFET Q1 is different from that of other NMOSFET Q1 due to fluctuation of potential caused by the concentration of impurities, potentials at the channel part of both MOSFETs Q1 are equalized instantaneously through the superconducting substrate 1. Consequently, fluctuation in the threshold voltage of NMOSFET Q1 can be prevented.

Patent JP-H05110275-A (JP)
Title: Card insertion guide mechanism
Inventor: KATO NAOTO
IPC: H05K7/14
Filed: 1991-10-14
Abstract: PURPOSE:To eliminate the need for excess parts, to reduce force for insertion and to regulate a position by installing a spacer for regulating the position of fitting near the connector of a moving body, releasing the regulation of a guide opposed to the spacer when the connector starts its fitting and controlling the guide until the connector starts its fitting. CONSTITUTION:A card 3 in the left and right direction is regulated by a holder 1 and no swinging is generated. Since swinging in the vertical direction is often generated, however, vertical positions are controlled by a spacer 4 and a guide 2 before a connector 5 is fitted. When fitting is started, excess force for insertion is unnecessitated because the spacer 4 crosses over the guide 2. The holder 1 fills the role of regulation in the left and right direction of the card 3. When projections are formed on the outside of the card 3 side only to a first section, where the card 3 is slid, and a section slightly before the card is fitted to the connector 5 and a guide 2 for regulating positions is formed on the inside of the holder 1 side, force at the time of the insertion of the connector 5 is further reduced.
