Patent JP-S5828826-A (JP)
Title: Preparation of semiconductor device
Inventor: SHIBATA KENJI
IPC: H01L21/265
Filed: 1981-08-12
Abstract: PURPOSE:To realize three dimensional integration of an element with sufficient characteristics for practical use by forming the inter-element isolation insulator region on the insulator substrate simultaneously with the single crystal layer on the basis of self-alignment and without any horizontal level difference. CONSTITUTION:The SiO2 film 102 is formed in the thickness of about 1mum as the insulating film on the surface of the P type single crystalline silicon substrate 101 with orientation 100 and the SiN film 103 is also formed thereon. Thereafter, the polycrystalline silicon layer 104 in the thickness, for example, of 5,000Angstrom  is formed on the surface of the SiN film 103. Next, a substance which will become the mast for ion implantation, for example, the resist layer 105 for photoetching is formed with the known technique in a part of the silicon layer 104 and the oxygen ion, for example, is also implanted to the other part. Thereafter, the resist layer 105 is removed, and said silicon layer 104 is annealed through irradiation of energy beam from the upper side. This annealing process realizes simultaneous deposition of the single crystalline region 106 of the fine pattern at the element forming area and the insulating region 107 at the inter- element isolation area on the basis of the self-alignment.

Title: Control device for operation of medical photographing apparatus
Inventor: ABE KATSUHIDE
IPC: A61B6/00
Filed: 1990-05-17
Abstract: PURPOSE:To avoid wasteful scan and secure the safety of a person to be inspected, by placing output from sensing when the person has done a will transmit conduct, and temporarily interrupting or stopping the motion of this photographing apparatus for medical service concerned in response to this output from sensing. CONSTITUTION:A system controller 4 is equipped with functions as a transmit conduct sensing means 5 and a photographing motion control means 6. In case a person to be inspected (p) launches in disorder in physical condition while lying on a frame 1, the operator P pushes a switch 7, and now a control signal for temporary interruption or stopping is sent from the photographing motion control means 6 to a frame sequencer 3 even though the operator is not aware of it and does not make interrupting or stopping operation. Thus, the sequence motions of different parts of the frame 1 are interrujted or stopped. This allows avoiding wasteful scan on the frame 1 and ensures the safety of the person to be inspected P.

Abstract: PURPOSE:To coat uniformly a plastic on a wire rod at a high speed with simple constitution without disconnection by supporting a coating die on a support by means of elastic materials displaceably in any of the direction at a right angle to the central axial direction of the central axial line of the tapered nozzle thereof. CONSTITUTION:When a traveling wire rod 4 passes through the inside of the tapered nozzle 2 of a coating die 1 contg. a plastic coating material 3, the hydrodynamical load stress acting to bring the center of the rod 4 always toward the center of the nozzle 2 exerts on the rod by the plastic coating material 3 in a fluid state passing in the nozzle 2 together with the rod. When the center of the rod 4 deviates from the center of the nozzle, the force acting to correct the deviation is generated. The die 1 is supported to a support consisting of upper and lower support plates 6, 7 so as to be made movable in any of the direction at a right angle to the central axial line of the nozzle 2 by means of elastic materials 9; therefore, the position thereof is corrected by moving minutely the die 1.
