Title: Two-dimensional image detector
Inventor: TERANUMA OSAMU
IPC: H04N5/369
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To improve the structural strength and maintain the connection between an active matrix board and a counter board even if a conductive material has little or no adhesive strength. SOLUTION: A space 23 between the connecting surface of an active matrix board 1 and that of a counter board 2 is evacuated by sucking through several through holes 22 formed in a seal agent 21 which is arranged all around the periphery of both connecting surfaces. As a result, a pressure difference is produced between the space 23 and an external atmosphere, and hence both boards 1 and 2 generate pressuring forces equivalent in directions of their being connected to each other, whereby a photosensitive conductive resin 3 can reinforce the connection between the boards 1 and 2. Since a gap holding material 25 is disseminated over both boards 1 and 2, it does not occur that the gap between the boards 1 and 2 will be reduced to the particle diameter of the material 25 or less.

Title: Manufacture of semiconductor device
Inventor: ONO TOSHIHIKO
IPC: H01L21/304
Filed: 1979-07-30
Abstract: PURPOSE:To prevent the inversion of the electroconductive type of p-type Si crystal grown by the Czochralski process, by replacing the n-type changeable thickness portion of a p-type Si semiconductor substrate with polycrystalline Si. CONSTITUTION:A polycrystalline Si layer 3 is grown on the p-type Si semiconductor substrate 1. The obverse side of the substrate 1 is then ground by lapping or the like. An n-type Si semiconductor layer 2 is epitaxially grown on the lapped reverse side of the substrate 1. Aafter that, elements are manufactured in the layer 2. Since the n-type invertible portion of the substrate 1 is replaced with the polycrystalline substance independent of the inversion, no n-type inversion takes place in the substrate 1. As a result, the semiconductor device of high reliability is manufactured  although additional processes such as the growth of the polycrystalline Si layer and  the grinding of the substrate are needed.

Title: Tape controller
Inventor: MIYAMOTO MAKOTO
IPC: G11B15/60
Filed: 1985-05-08
Abstract: PURPOSE:To always secure the coincidence between the recording and reproducing position on a tape by tilting a head with rotation in response to the tape driving direction to tilt the head to the tape and securing contact between the tape and a tape guide for control of the tape. CONSTITUTION:The action of a plunger 14 is stopped when a tape 18 is driven in the forward direction and a head 11 is tilted toward a head substrate 16 with the energizing force of a spring 14a as shown by an arrow head B1. Then the tape 18 slides along a sloping surface and touches a tape guide 12a at the side of the substrate 16. Thus the tape 18 is controlled. When the tape 18 is driven reversely, the force is produced against the force of the spring 14a toward an arrow head B2 when the plunger 14 is actuated. Then the head 11 is tilted in the direction opposite to the substrate 16. Thus the tape 18 slides along a sloping surface and touches a tape guide 12b set at the side opposite to the substrate 16. Then the tape 18 is controlled. As a result, coincidence is always secured between the recording and reproducing positions on the tape 18.
