Title: Method for controlling plate thickness in rolling, press welding machine
Inventor: UMEMURA HIROO
IPC: B23K20/04
Filed: 1982-04-15
Abstract: PURPOSE:To control plate thickness more accurately, by calculating the plate thickness value of measuring reference basing on the fluctuation of plate thickness in at least one revolution of a roll, and ajusting a roll gap by comparing it with the standard plate thickness value. CONSTITUTION:The latter roll of a pair of rolls 1, 2 having the same diameters respectively is supported in only a rotatable state by a machine frame of a press welding device, and the former one is supported in a rotatable and vertically movable state, and a mechanism 3 for adjusting the gap between both rolls is interlocked. Band plate materials 5, 6 are mutually press welded into a press welded material 7 between the rolls 1, 2, and the thickness of it is measured by a flying micrometer 8 to output its value to a microcomputer 10. On the other hand, a proximity sensor 11 detects that the roll 2 completes one revolution and inputs its signal to the computor 10. The computor 10 measures the fluctuations of the plate thickness while the roll 2 completes one revolution and calculates the plate thickness value of measuring reference, and controls a driving motor 4 of the mechanism 3 through a control panel 12 in accordance with the deviation of the calculated value from the standard plate thickness in order to control the gap between the rolls.

Title: Semiconductor device
Inventor: SATOU NAONOBU
IPC: H01L21/60
Filed: 1984-04-02
Abstract: PURPOSE:To enhance the electrostatic breakdown resistance of each terminal of a contact by forming a plurality of wiring layers, increasing the length of aluminum wirings for connecting a bonding pad to elements such as a diffused resistor or the like, thereby preventing an abnormal contact alloy from producing. CONSTITUTION:Wiring layers 5 between a bonding pad 1 and a contacting hole 4a are formed of the first wiring layers L1, L2 along the side A of the pad 1 and the second wiring layer remote from the pad 1, and the first wiring layer is increased in length than the second wiring layer. Thus, even if a distance (l) between the pad 1 and the contacting hole 4a is short, the substantial distance can be sufficiently increased due to the presence of a plurality of the first wiring layers, thereby effectively preventing the material of the pad from penetrating into a semiconductor portion.

Title: Recording head with side shield
Inventor: SHIYAIAMU SHII DASU
IPC: G11B5/09
Filed: 1989-03-15
Abstract: PURPOSE: To make it possible to substantially shield a reading/writing head from adjacent tracks by including a magnetic side part shield arranged adjacently to a magnetic pole. CONSTITUTION: For example, a three-pole head 16 is a perpendicular head for reading/writing. The magnetic pole P2 is a reading magnetic pole which is conductive, i.e., is of a magnetic flux sensing type. The magnetic pole P1 is a writing magnetic pole and the magnetic pole P3 is a downstream magnetic pole and has the side part shiel part 18. If this head shape is provided with a soft magnetic lower layer and is used for perpendicular direction recording, the edge magnetic field in the perpendicular direction attenuates exponential- functionally together with a distance. The magnetic fluxes from adjacent tracks are blocked by using the side part shield 18 during reproduction, by which the pass of these magnetic fluxes through a sensor is prevented. As a result, the substantial shielding of the magnetic poles from the adjacent tracks on a magnetic medium is made possible.

Filed: 1983-04-11
Abstract: PURPOSE:To automate polishing without causing damage onto the surface of a thin chip by fixing a thin chip to a fixing board secured rotatably to a revolvable pressure shaft then pushing the thin chip against a rotating backup wheel and polishing. CONSTITUTION:When polishing a single crystal wafer such as gallium arsenide thin chip, said thin chip is fixed to a fixing board 5 secured rotatably to a pressure shaft 6 revolving with such speed as revolve one time with time necessary for polishing. Then said thin chip is pushed with predetermined pressure against a backup wheel 7 for lowering the pressure shaft 6 through an elevating mechanism 10 and rotating thereafter said thin chip is polished while being revolved through a revolving mechanism 11 on the wheel 7 face. Thereafter the pressure shaft 6 reached to the thin chip mount/dismount position after one revolution period is lifted to remove the polished thin chip. Consequently the polishing work can be automated easily without causing scratch on the surface of thin chip.

Title: Semiconductor device
IPC: H01L29/812
Filed: 1992-03-23
Abstract: PURPOSE:To enhance an electrostatic breakdown resistance of an input circuit in which a junction type transistor is used as a basic configuration without decreasing its input impedance.

Abstract: PURPOSE:To separately manufacture a Josephson junction element and a flux flow element with a good reproducibility and to provide a method for manufacturing an oxide superconductor junction element which has a good reproducibility of a current-voltage characteristic of each element by using a focused ion beam. CONSTITUTION:This is a method for manufacturing an oxide superconductor junction element using a weak bonding section which occurs in an oxide superconductor film. A very small deteriorated region is formed on a singlecrystalline substrate 11 using a focused ion beam such as a Ga ion beam.
