Abstract: PURPOSE:To obtain high output and to improve CSS durability by laminating a film, ferromagnetic metal thin film, hard carbon film and lubricant layer on a nonmagnetic substrate. CONSTITUTION:An Al-alloy nonmagnetic substrate 5 is subjected to surface polishing but not to anodizing treatment. A polyester film 6 has a fine particle coating layer having dispersion of fine particles in a resin in 1-10mum thickness. A ferromagnetic metal thin film 7 of Co-base alloy consists of aggregation of columnar fine particles showing good magnetic separation among the columnar particles. The hard carbon film 8 has <=100Angstrom  thickness and has excellent durability, and is formed by sputtering a graphite target or plasma CVD method with methane gas or the like. A lubricant layer 9 is formed by wet coating or vapor deposition. The substrate 5 and the film 6 are adhered with an adhesive 9. By this method, the polymer film 6 absorbs the stress from a head to prevent damages, so that even when the diamond-like hard carbon film 8 is made thin, durability can be maintained and high output is obtd.

Title: Amorphous silicon photoelectric element
Inventor: HAMAKAWA YOSHIHIRO
IPC: H01L31/04
Filed: 1983-03-16
Abstract: PURPOSE:To enable to largely improve the efficiency, by using the P type doped thin film of amorphous Si carbide for a P-layer. CONSTITUTION:The amorphous Si carbide is obtained by the plasma decomposition or preferably glow discharge decomposition of silicon hydride (SinH2N+2) of silane, etc. and hydrocarbon of methane, ethane, etc. The amorphous Si carbide is used as a P type a-SiXC1-X:H by doping an element of periodic law IIIgroup such as boron. The doping amount is arbitrary; however, in case of doping e.g. with B2H6, the effect is insufficient because the coefficient of absorbing light wherein the prime number of B atoms/number of (Si+C) atoms is 4% or mor-increases largely, and, in case of 0.05% or less, the shift or Fermi level is small, therefore junction formation is insufficient and not desirable.

Filed: 1988-02-26
Abstract: PURPOSE:To easily detect the value of a potential in a multilayer interconnection structure by a method wherein a part directly on a conductor wiring part is formed by an insulating film which is partially different from another film and the thickness between the different insulating film and the conductor wiring part in its layer is made equal to the thickness of the insulating film directly on the conductor wiring part in an uppermost layer.

A silicon oxide film 6 is formed partially only on the wiring part 3 instead of a silicon nitride film 4. The thickness of the nitride film 4 between the oxide film 6 and the wiring part 3 is made equal to the thickness of the nitride film 4 on a second aluminum wiring part 5. When an electron beam tester is used, only the oxide film 6 on the wiring part 3 is etched and removed; the thickness of the nitride film 4 on the wiring part 3 is made equal to that on the wiring part 5; potentials are compared under an identical condition. By this setup, the value of the potentials in a multilayer interconnection structure can be detected easily.

IPC: G01C5/00
Filed: 1985-03-06
Abstract: PURPOSE:To measure a driving angle of a ball with extremely high accuracy by detecting a drop of a level of a photodetected signal at the time when the driven golf ball crosses the scanning space of laser beams and performing the prescribed arithmetic for said drop of level. CONSTITUTION:The laser beams are photodetected by an optical fiber 50 and scanned to 3kHz by a scanner 2 and the scanning space 71 is formed. When the driven ball crosses this space 71, the level of the photodetected signal (a) drops. Then, a signal at the time when the ball starts and ends to shield the light,a signal of a scanning end and a clock pulse are sent to a control circuit 6. The clock signal is calculated with a counter 62 by the control signal (j) and inputted to an arithmetic circuit 64 as a time signal (g) and since the number of these pulses is changed by the driven angle, the height (H) is calculated on the basis of a prescribed calculating formula and the angle is calculated from the horizontal distance (L). Accordingly, the driven angle is measured with high accuracy.

Title: Method of manufacturing batch apertures for electron beam exposure system
Inventor: YAMASHITA HIROSHI
IPC: G03F1/20
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent the front surface from eroding away by an etchant during the etching of the back surface, while simplifying a manufacturing process, etching different locations with different depth and improving fabrication accuracy by etching a substrate using focused ion beam. SOLUTION: First, focused ion beam 1 is applied to the front surface of a Si substrate according to a pattern data under a vacuum, and the surface of the Si substrate is etched as desired. A film thickness d is then sufficiently thickened so that the film absorbs and disperses electrons, energy loss and emitting angle distribution are changed, and consequently electrons passing through the film are unable to reach the Si substrate 2, or satisfactory contrast can be obtained, even though electrons passing though the film reach the Si substrate 2. Next, the Si substrate 2 is turned over, and an opening 10 is obtained by scanning the back surface of the Si substrate 2 except for the periphery with a focused ion beam 1 to uniformly etch the back side up to a predetermined depth. Thereby, batch apertures are completed.

Abstract: PURPOSE: To surely conduct the pressing operation on a bar steel and the synchronizing operation on multiple bar steels by one manipulation as well, by arranging a pressure bar for pressing the surface of a bar steel at right angles in the flying direction of bar steels.  
     CONSTITUTION: A vertically movable cylinder 10 is put into operation when twin bar steels 1a, 1b transferred by a loller table 2 come to a predetermined cutting position and a riding beam 9 is lowered along guide poles 5, 6 bring the lower end of the beam 9 into contact with both upper surfaces of bar steels 1a, 1b and press them. The riding beam 9 is parallely lowered to evenly press both bar steels. With the aid of the friction force caused between the beam 9 and the bar steels 1a, 1b, the shear moves synchrnously with the flying speed of bar steels and shears off bar steels while transferring a shearing torch 15 by a horizontally traveling frame 14. In case that casting is stopped for one 1b of bar steels by some reason, the rightest end of the beam 9 is lowered by a jaw 8 and the leftest end is loaded above the other bar steel 1a, and therefore, there is no problem for keeping synchronized movement of the shear.

Abstract: PROBLEM TO BE SOLVED: To prevent a remarkable rise in a brake temperature by switching inter-vehicle distance control so as to reduce a deceleration frequency by brake driving when judging the deterioration of brake performance. SOLUTION: When a traveling speed of a preceding vehicle follows at a speed lower than a preset vehicle speed, and when a brake temperature detected by a brake temperature sensor 6 becomes a control switching temperature or more predetermined by a system in an inter-vehicle distance control part 102, preset inter-vehicle time is increased, and an inter-vehicle distance follow-up responsiveness control parameter is changed so that responsiveness of inter- vehicle follow-up performance becomes dull to arithmetically operate a vehicle speed command value. A throttle actuator 13 is closed according to the vehicle speed command value in a vehicle speed control part 103, and deceleration by shift-down is peformed by an AT controller 14. When sufficient deceleration cannot be performed, deceleration control by driving of a brake actuator 12 is added.
