Title: Change-over of operation pattern in hydraulic circuit drive device and its device
Inventor: YASUDA TOYOTARO
IPC: E02F3/43
Filed: 1994-01-13
Abstract: PURPOSE:To speed up other processing in a controller by distributing computation and memory functions, necessary in changing operation pattern, to plural operation levers etc., from a controller. CONSTITUTION:A operation pattern selected by a operation pattern selection unit 6 is transmitted from a controller 5 to operation levers 3a, 3b and operation pedals 3c through communication line, and thus stored in a memory portion 3me contained in each operation pedal 3c etc. When all the operation pedals 3c etc, are operated, a hydraulic actuator 1a etc., combined with the operated operation pedals 3c etc. are read from the memory portion 3me according to a selected operation pattern. Operation signals taken in through an angle sensor 3se and an A/D converter 3co are converted to command signals for control valves driving all hydraulic actuators 1a, etc., by an arithmetic portion 3op. Command signals are outputted to the controller 5 through an output portion 3ou so that the read actuators etc., 1a are driven.

Title: Rotary magnetic sheet device
Inventor: SHIOKAWA HIROSHI
IPC: G11B19/04
Filed: 1985-01-10
Abstract: PURPOSE:To prevent double recording and to perform high-speed continuous recording by reproducing recorded signals while moving a magnetic head reverse ly and successively from a final track position in one direction when a magnetic sheet is loaded. CONSTITUTION:When a stepping motor 117 is driven clockwise, a gear B116 rotates clockwise and a gear A110 rotates counterclockwise. The rotation is transmitted from a cam 109 to the projection 104a of a slider 104, so that the slider 104 mounting the magnetic head 112 moves along guide shafts A102 and B103. When the stepping motor 117 is reversed, the magnetic head moves in the opposite direction. Annular tracks are formed on the magnetic sheet for recording and reproduction to perform continuous recording and reproduction in one direction and signals are reproduced successively while the magnetic head is moved in the opposite direction of the final track position in said direction to detect tracks which are already recorded, a track following a track where a signal is reproduced firstly in the recording and reproducing direction is regarded as a recording start track. Consequently, double recording is prevented and high-speed continuous recording is possible, and the cost is reduced.

Title: Manufacture of semiconductor device
Inventor: HARA TOSHIO
IPC: H01L21/322
Filed: 1985-01-10
Abstract: PURPOSE:To provide a defective-free layer having an improved crystallizability near the surface and to provide internally a defective layer, by subjecting silicon single crystals containing a small amount of nitrogen and having a content of oxygen of about 5X10<17>/cm<3> to low-temperature and high-temperature heat treatments. CONSTITUTION:Nitrogen ions are implanted in a silicon substrate 11 whose initial content of oxygen is 4-10X10<17>/cm<3>. The substrate is then subjected to a low temperature (650-850 deg.C) heat treatment and to a high temperature (1,000-1,200 deg.C) heat treatment so that a defect-free layer 13 is formed in the surface region and a defective layer 12 is formed internally. This defective layer 12, which is formed in the portion having a nitrogen concentration of 10-50ppba, has an effect of gettering impurities and allows an element formed in the defective-free layer 13 to have stable characteristics. Further, the defective-free layer 13, which is formed in the silicon crystals having a low oxygen concentration, presents a fairly desirable crystallizability.

Title: Production of magneto-optical recording medium
Inventor: MOTOMIYA KAZUOKI
IPC: G11B11/105
Filed: 1987-01-10
Abstract: PURPOSE:To permit uniformization of not only a film thickness but coercive force as well over a large area by using a material in which the compsn. ratio of a rare earth element with respect to a transition metal is larger toward a peripheral part from the central part of a target or the part near the same as an alloy target. CONSTITUTION:The ratio at which spattered particles sticks to a substrate is a function of the distance from the point on the target and decreases with an increase in the distance; the degree of the decrease is also a function of the distance from the center of the target. The ratio at which the particles stick even to the part of the substrate slightly apart from the center thereof is larger as the eroded part parts further from the center of the target. The amt. of the rare earth element of the particles splashed from the eroded point near the periphery from the center of the target, is, therefore, decreased in order to prevent the increase in the rare earth element with an increase in the distance from the center on the substrate. The amt. of the rare earth element in the recording film of the laminated magnetic material is thereby increased near the center on the substrate. The uniformity of Hc is thus improved.

IPC: H01J29/87
Filed: 1993-01-11
Abstract: PURPOSE:To achieve excellent explosion-proof effect by using a cloth tape consisting of a dense part and a coarse part in terms of cloth density, as a noncombustible cushioning material. CONSTITUTION:A noncombustible cushioning material 22 is wound around the vicinity of a front maximum outer peripheral part of a panel 1. The cushioning material 22 comprises glass cloth tape consisting of a dense part and a coarse part in terms of the cloth density. The cloth density of the cushioning material 22 is approximately 50 pieces/25mm in the side of a phosphor surface 4, while it is 15 pieces/25mm in the side of a funnel into which an adhesive is to be injected. A metal band 23 is tightly fastened on the cushioning material 22. The adhesive to be injected between a panel 1 and the band 23 after heating and exhausting processes, is surely permeated into the cushioning material 22, while the adhesive is not leaked, and the adhesion area between the panel 1 and the band 23 is expanded. The adhesive force between the panel 1 and the band 23 is thus increased, even when a bulb body is destructed and implodes, dispersion of glass fragments is minimized, and the explosion-proof effect can thus be improved.
