Title: Polishing device
Inventor: UEDA KATSUNOBU
IPC: B24B37/00
Filed: 1987-02-23
Abstract: PURPOSE:To perform the polishing of a specific microscopic area highly accurately and efficiently, by making an abrasive solution severely move to flow by a laser beam, and polishing a workpiece in a way of utilizing a collision of abrasive grains against the workpiece through this flowing force. CONSTITUTION:In the state that a workpiece 2 is dipped in an abrasive solution 1, a laser beam 4 out of a laser generator 9 is irradiated to the workpiece 2 from the head part opposed, as far as 1mm or so, to the required part of a surface of the workpiece 2 at a positioning part 6 via an optical fiber part 10. Light energy inherent in this laser beam 4 is changed to heat energy, raising a temperature of water 7, and it is severely moved to flow with a convection current or a turbulent flow as in an arrow 17, therefore abrasive grains 8 collide with a work surface 12, thus polishing takes place. Thus, even in the case of polishing for a microscopic area of less than mm order or only a specific local part of the workpiece, it is performable highly accurately and efficiently.

Inventor: OHASHI MASAAKI
IPC: B29C45/26
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent the surface of a resin molded body just after the removal of the body from a mold from having a gate part mark thereon by a method wherein a block having a surface movable parallel to at least some surface of a mating part is provided so as to shut off a gate part, which is provided parallel to the mating part surface, through the forward and backward motions of this block. SOLUTION: At a mating part A made by a fixed retainer plate 1 and a movable retainer plate 2, a cavity 3, which corresponds to the shape and dimensions of a resin molded body, a runner 4 and a gate 5 are formed. To the movable retainer plate 2, a plurality of ejector pins 6 and 7, which are arranged slidably and reciprocated by a driving means are equipped. To the fixed retainer plate 1, a block 8, which moves parallel to the mating part A so as to cut off the gate, and a spring 9 for pushing back to the block 8 are equipped. Thus, through the reciprocating motion of an ejector rod, the block 8 can be moved so as to cut off the gate 5. Through a molding, in which the above-mentioned constitution is employed, the surface of a discharged resin molded body has no gate part mark.

Title: Picture processor
Inventor: KURONO TAKEHIRO
IPC: G06V10/145
Filed: 1991-03-05
Abstract: PURPOSE:To improve accuracy for recognition or the like and to prevent information (features) from being lost by picking up the image of an object from the front and irradiating this face to pick up the image of the object with light from a direction different from right in front. CONSTITUTION:The light emitted from a lighting means 3 generates much more shadows in comparison with photoirradiation from the right in front, and the face directing the irradiating direction is made bright. Namely, the unevenness of the image pickup face is emphasized by the shadow and can be obtained as contrast information. On the other hand, by irradiating the object with light selectively from plural directions, the various contrast information of the same copy can be obtained. When the lighting point of the lighting means 3 and the image pickup point of an image pickup means 2 are arranged on one straight line, brightness/darkness is emphasized in the direction of this straight line and is not emphasized in a direction orthogonal to this straight line. In this case, a compression processing is executed at a low degree according to the direction of emphasizing brightness/darkness, the amount of data in the useless direction can be reduced, and information can be secured in the required direction.

Abstract: PURPOSE:To reduce the number of connecting wires between a discharge heater and a driver by making wiring for driving an electrothermal converter a matrix wire pattern. CONSTITUTION:Digit terminals for common signal DG0 to DG15 are sequentially turned ON starting with DG0 in the time-dividing mode. During this process, a segment signal is connected t segment terminals Seg0 to 7 based on recorded data for a single block selected using the common signal. Then each transistor corresponding to each one of the segment terminals Seg0 to Seg7 is driven in accordance with signals P0 to P7 to connect a segment signal. In addition, transistors and FETs corresponding to each one of the digit terminals DG0 to DG15 on the common side are driven in response to signals S0 to S15 to connect a common signal. A driver control circuit which controls a driver circuit generates control signals P0 to P7, S0 to S15. Consequently, the number of wires for connecting an electrothermal converter to a circuit for driving the converter decreases and recording mode is diversified.
