Inventor: KASHIO YUKIO
IPC: B41N1/24
Filed: 1988-03-16
Abstract: PURPOSE:To eliminate a part of a light-reflecting film conductive layer abutted by an electrically conducting member to rapidly and sharply print hand-written characters and drawings, etc., on a large number of bodies to be recorded in a simple manner, by applying a predetermined electric potential difference between the electrically conducting member and return electrode. CONSTITUTION:An original plate material sheet 1 consists of a transparent resin base layer 1a and a light-reflecting film conductive layer 1b vapor-deposited on one surface of the base layer 1a. An electrically conducting member 2 is traveled on the light-reflecting film conductive layer 1b under being abutted thereto to write an arbitrary character, etc. At this time, a predetermined potential difference between the electrically conducting member 2 and a return electrode 3 is applied from a power source 4, whereby an electric current conduction action is generated to eliminate a part of the light-reflecting film conductive layer 1b abutted by the conducting member 2. This cut out part 1b1 forms an image part 6 of an arbitrary character, etc., on the light-reflecting film conductive layer 1b. In this manner, am original plate 7 is simply and easily made from the original plate material sheet 1. Ink corresponding to the image part 6 is melted by a light-heat conversion to be transferred to a body to be recorded 10.

Filed: 1995-03-22
Abstract: PURPOSE: To provide a pipe lining material capable of achieving the cost reduction and the enhancement of handling properties by reducing the thickness thereof even with respect to a large caliber pipeline and not extremely narrowing the cross-sectional area of the pipeline after lining. CONSTITUTION: A second pipe lining material 7 obtained by winding a plurality of strip like reinforcing members 6 around the outer peripheral surface of a tubular resin absorbing material 5 in a peripheral direction thereof in a ring form so as to provide a proper interval in the longitudinal direction thereof is incorporated in a first pipe lining material 4 obtained by applying a plastic film 3 high in airtightness to the outer peripheral surface of a tubular resin absorbing material 2 to constitute a pipe lining material 1. Since the pipe lining material 1 is reinforced by the reinforcing member 6, the thickness of the pipe lining material 1 necessary for ensuring necessary strength can be reduced and, especially, in the pipe lining material 1 for the large caliber pipeline, cost reduction and the enhancement of handling properties can be achieved by reducing the thickness of the pipe lining material and the cross-sectional area of a pipeline after lining is not extremely narrowed by the pipe lining material 1.

Filed: 1991-03-27
Abstract: PURPOSE:To offer the waveguide type optical switch element which has low loss, a high extinction rate and small polarization and wavelength dependency. CONSTITUTION:The semiconductor optical switch element consists of two parallel optical waveguides 1 and 2 which are mounted with electrodes 7 and 8 for electric signal input and one optical waveguide part 9 consisting of a tapered optical waveguide part 9b which is arranged at the center position between the optical waveguides 1 and 2 for output and decreases gradually in path width from an input terminal 9a in the propagation direction of light and a straight optical waveguide part 9c which is connected optically to the tapered optical waveguide part 9b. Consequently, the waveguide mode of one optical waveguide for output can be cut off by operating the electrodes, so light which is inputted to the center optical waveguide for input is coupled with the other optical waveguide for output to obtain a 0  1 switching characteristic. The dependency on polarization and wavelength is small and the low loss and high extinction rate are obtained.

Title: Method of processing wafer
Inventor: NAKAI RIYUUSUKE
IPC: H01L21/324
Filed: 1985-03-29
Abstract: PURPOSE:To carry out improved wafer processing to remove strain on the surface, by grinding the outer periphery of compound semiconductor crystal, annealing it, and slicing it. CONSTITUTION:In grinding the outer periphery of compound semiconductor, followed by slicing it to give a wafer, after the grinding of the outer periphery is over, the crystal is annealed. Thus, strain is sufficiently removed only by annealing after the grinding, and a greater effect can be obtained by further etching followed by the annealing treatment after the grinding of the outer periphery. Preferably the annealing is carried out at about 400-100 deg.C for >=10min. The causes of breakage are considered to be strain in the vicinity of the surface, stress concentration, microcrack, etc., and they are brought about by uneven distribution of dislocation. Consequently, the causes are eliminated by the annealing treatment, and the wafer becomes slightly breakable.

Title: Pneumatic pressure control device of press machine
Inventor: KUBOE KAZUHIRO
IPC: B30B15/02
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To precisely set a pneumatic pressure of an actuator in a short tine by operating a solenoid valve for a stored pulse time at the time of a small difference between a set pneumatic pressure and actual pneumatic pressure and operating a solenoid valve while taking operation delay of solenoid valve into account at the time of large difference therebetween. SOLUTION: Pneumatic pressure is controlled by respectively arranging first/second solenoid valves 2A, 2B between a pneumatic source 1, the atmosphere and an actuator 3 of press machine. In the pneumatic pressure control device, by varying reference pressure differences of the pressure difference between the actuator 3 and air source 1 obtained with pressure sensors 12, 13 and the pressure difference between the actuator 3 and atmosphere, the solenoid valves 2A, 2B are pulse operated. The pulse time needed for unit amt. variation of operating pressure difference before/after operation is stored. When a difference between a set pneumatic pressure of the actuator 3 and actual pneumatic pressure is small, the first of second solenoid valves are operated for a pulse time at the time of stored reference pressure difference.  When a difference is large, the solenoid valves are appropriately operated to control pneumatic pressure by using the operating pressure difference stored while taking operation delay of solenoid valve into account.
