Title: Graphic input device
Inventor: OHORA SHINICHIRO
IPC: G06F3/0488
Filed: 1990-08-30
Abstract: PURPOSE:To output graphic data with variable density by accumulating charge corresponding to a voltage in ferroelectrics arranged on a table face in a matrix in the X and Y directions by means of a writing brush-like input pen. CONSTITUTION:Power supply voltage is applied to the brush 231 of the input pen 23. When the surface of the tablet 11 is traced by the pen 23 in said status, the voltage is applied to ferroelectrics 12 existing in the traced area and charge is generated. The generated charge is increased/decreased in accordance with the applied voltage. Thereby, a graphic signal based upon an analog voltage can be obtained by extracting the voltage impressed to the X and Y electrodes in the ferroelectrics 12 by multiplexers 13, 14. When the surface of the tablet 11 is traced by the input pen 23 while changing its voltage, charge is simultaneously generated in the plural ferroelectrics 12, these charge values can be extracted as a voltage to use as the input of tablet face, and the variable density of a graphic can be expressed by the voltage levels.

Abstract: PURPOSE:To improve the reliability of electrical connection and to facilitate a mounting operation by inserting a pin-shaped electrode of a mounting base into the cylindrical electrode of a thin-film magnetic head chip and joining the positioning surfaces of the thin-film magnetic head chip and the mounting base to each other by an adhesive. CONSTITUTION:The mounting of the head chip 20 to the mounting base is executed by pushing the pin-shaped electrode 33 into the cylindrical electrode 26 while sliding positioning surfaces 23, 31, then adhering the positioning surfaces 23, 31 to each other. Then, the cylindrical electrode 26 of the head chip 20 and the pin-shaped electrode 33 of the mounting base come into contact with each other and a coil conductor and the pin-shaped electrode 33 are electrically connected.

Title: Cutting equipment for machining timber
Inventor: NISHII SHIGEO
IPC: B27C1/10
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To enable cutting of a projecting or recessed curved surface of timber as well as a flat surface thereof by providing means for fixing elevatable copying plates and actuating means which bring the lower edge parts of the copying plates into contact with a cutting surface of the timber by actuation under the condition of cancellation of the fixation. SOLUTION: When fixation of copying plates by copying plate fixing means 46 is canceled, plate edge parts thereof are projected by actuation downward from a rear-side case 6 and an elevating case 24 of an equipment main body 1. When the lower edge parts of the copying plates 43 are pressed on a cutting surface S of timber T in this state, the attitude of the lower edge parts is so varied as to copy after the cutting surface S of the timber T to be cut, against the actuating force of the actuating means 44, irrespective of whether the cutting surface is a flat surface or a projecting or recessed curved surface. When the copying plates 43 are fixed herein by the copying plate fixing means 46, a virtual base surface along the cutting surface S is formed.  By regulating the height of the elevating case 24 in conformity with a cutting margin and by sliding cutting equipment back and forth along the cutting surface, plane finishing can be performed mechanically by a plane iron 17 of a rotary cutting tool 15.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of foam in a glass caused by the contact of the fused glass with a refractory by treating the refractory used as a feeder parts of a glass fusing oven with a sodium hydroxide aq. solution having a specific canon., and firing. SOLUTION: The following treatment is carried out on the refractory used as the feeder parts (orifice, plunger, tube, spout or the like) of the glass fusing oven: The refractory is dipped into the sodium hydroxide aq. solution having >=10wt.% concn. and, after dried, fired at 100-1400 deg.C.

Title: Method and device for high-efficiency sheet plasma sputtering
Inventor: URAMOTO JOSHIN
IPC: H01L21/203
Filed: 1989-09-05
Abstract: PURPOSE:To form a uniform thin film on a large-area substrate by deforming an arc-discharge plasma current into a sheet shape by a magnetic field, passing the sheet plasma between a target and the substrate, and thereby sputtering the target with high efficiency. CONSTITUTION:The arc-discharge columnar plasma current 1 is passed through at least a couple of permanent magnets 2 and 2 enclosing the current. A magnetic field vertical to the initial magnetic field 4 in the axial direction of the plasma current is impressed by the magnet 2. As a result, the columnar plasma current 1 is deformed into a thin and wide sheet to form a sheet plasma 3, and the sheet plasma 3 is passed through the target 5 and substrate 7 opposed to each other. A bias voltage is further impressed by a DC power source 6 between an arc-discharge anode 8, on which the sheet plasma 3 is converged, and the target 5. Consequently, the ion in the sheet plasma 3 is accelerated and allowed to collide with the negatively charged target 5 which is sputtered. By this method, the large-area target 5 is sputtered, and a film is uniformly formed on the substrate 7.
