Title: A cutter-grindstone shaping device
Inventor: MATSUOKA AKIRA
IPC: B24B53/00
Filed: 1978-02-16
Abstract: PURPOSE: To make it easy to shape the end part of a cutter-grindstone while it is set mechanically, by placing a shaping grindstone, via a spring, at the end part of a lever which moves back and forth at a fixed angle.  
     CONSTITUTION: By the operation of a motor, end part 5a of an eccentric pin is caused to make circular motion, and end part 5a causes lever 9, which is placed in oblong hole 14, to make reciprocating motion within a fixed angle. During this reciprocating motion, shaping grindstone 16 is brought into contact with one side of cutter-grindstone 19. When lever 19 turns, spring 15, which is placed between lever 9 and shaping grindstone 16, bends, and when the degree of its bending becomes large, shaping grindstone 16 moves away from cutter-grindstone 19 and goes to the other side. Next, when lever 9 returns to its former position, shaping grindstone 16 is brought into contact with the other side of cutter-grindstone 19 and operates shaping on it. When lever 9 continues to turn, spring 15 bends, and when the degree of its bending becomes large, shaping grindstone 16 moves to the one side of cutter-grindstone 19.

IPC: F16H9/12
Filed: 1983-02-07
Abstract: PURPOSE:To reduce the coefficient of friction in a sliding portion, make it shock-resistant, promote its durability and suppress its vibration, by making a sliding cylinder of a bearing material produced by mixing polyethylene tetrafluoride with a reinforcing filler, and by tightly fitting the cylinder on a drive shaft. CONSTITUTION:A sliding cylinder 10 is tightly fitted on a drive shaft 2. The cylinder 10 is made of a bearing material produced by mixing fluorine resin with a reinforcing filler of fiberglass, carbon fibers or a mixture of both of them. At that time, the bearing material is formed into the sliding cylinder 10 whose inside diameter 10a is slightly smaller than the outside diameter 2a of the drive shaft 2. The drive shaft 2 is press-fitted into the sliding cylinder 10 as the cylinder is heated. When the cylinder 10 is cooled, it contracts due to not only the cooling but also its shape memorizing effect, so that the cylinder is firmly fitted on the drive shaft 2. According to this constitution, the frictional resistance to the sliding cylinder is reduced, the cylinder is made wear-resistant, its strength and shock resistance are heightened, and a vibration is prevented.

Title: Device for changing powdery material into slurry and derivering it
Inventor: NAKASHIMA MASARU
IPC: B65G53/30
Filed: 1980-02-15
Abstract: PURPOSE: To change a powdery material into slurry and deliver it, by using a jet machine whose water ejecting direction is altered.  
     CONSTITUTION: Valves 29aW29c are opened to eject water from an auxiliary jet nozzle 28 to change coal 10 in a well 5 into slurry and deliver it. A valve 27 is then opened to project a high-pressure water jet from a jet nozzle 22 onto coal 10 in a vessel 1 to change the coal into slurry. The slurried coal 10 flows into the well 5 and is delivered by an eductor 8. A drive mechanism for altering the direction of the water projection from the nozzle 22, is built in a jet nozzle machine 6. The jet nozzle 22 is swung and revolved around a horizontal axis at the same time when the nozzle machine itself 6 is continuously rotated around a vertical axis. The direction of the water projection is thus moved up and down in a range from an arrow 25a to another 25b so that the powdery coal 10 is efficiently changed into slurry and delivered.

Filed: 1989-01-27
Abstract: PURPOSE:To reduce dust adhering to a treated wafer by a method wherein the inner wall of a preliminary vacuum chamber linked with a vacuum treatment chamber is covered with a plastic film which can be renewed by repairing. CONSTITUTION:The inner wall of a preliminary vacuum chamber 4 which protects a vacuum treatment chamber 2 from significant decline of a vacuum degree when a wafer 1 is taking into and out of the chamber 2 is covered with a plastic film 6 which can be renewed by repairing. Thus, by covering the inner wall of the preliminary vacuum chamber 4 linked with the vacuum treatment chamber 2 with the plastic film 6 which can be renewed by repairing, even if moisture in the air, residual reactive gas in the vacuum treatment chamber or the like penetrates into the chamber 4, as no metal part such as aluminum or stainless steel is exposed, creation of 'rust' caused by the inner wall contamination of the preliminary vacuum chamber can be avoided. With this constitution, dust adhering to the treated wafer can be reduced.

Abstract: PURPOSE:To make any trouble in copying paper to be fed afterward preventable before it happens, by selecting a selector device so as to feed the next copying paper into a discharge tray when detecting a fact that length of the copying paper during conveyance is more than the specified one. CONSTITUTION:When a duplex mode or a composite mode is selected, a central processing unit or a controlling device sets a selector claw 60 to an upper step position and opens a passage leading to the side of a paper refeed cassette 50. And, when a tip of copying paper out of a pair of paper discharge rollers 21 is detected by a sensor Se2, it starts a copying paper length detecting time. Next, when a rear end of the paper is detected by the sensor Se2, it judges whether crossfeed of an A4 format is or not by the copying paper length detecting timer, and if NO is the case, the selector claw 60 is selected to the lower step position by a solenoid 62, and the copying paper is conveyed to the side of a paper discharge tray 45 from the paper refeed cassette 50 for the exclusive A4 format cross feed. Thus any drawback such as a paper jam or the like due to the copying paper of more than the specified length to be fed in afterward is preventable before it happens.
