Title: Insulator air blow apparatus of electric dust collector
Inventor: WATANABE HAJIME
IPC: B03C3/70
Filed: 1984-02-13
Abstract: PURPOSE:To hole an insulator to a good insulating state, by blowing off compressed air from the nozzles provided on the circumference of a rotary shaft and rotating the nozzles themselves by the propelling force of said compressed air while uniformly impinging air to the surface of the insulator to shake off dust. CONSTITUTION:When compressed air is sent into an air supply pipe 1, it passes a rotary joint 3, a rotary shaft 2, a branched pipe 4 and nozzles 5 to be discharged from blow-off orifices 6 as jet streams and the rotary shaft 2, the branched pipe 4 and the nozzles 5 are rotated by propelling force generated at this time. Therefore, air blown off from the blow-off orifices 6 are impinged to the entire surface of an insulator 7 and the surface of the insulator 7 receives uniform air blow to make it possible to prevent the remaining of dust receiving no shaking-off caused by the weakness of the air stream. Because the air blow-off orifices 6 are always moved, even if the accumulation of dust is once generated by the strong air stream, the air stream with proper power is impinged to the insulator 7 directly thereafter and, therefore, dust is easily shaken off. As a result, the surface of the insulator 7 is always held in a good insulating state.

Title: Reaction method, hydrophilic pigment, and recording liquid
Inventor: HORIUCHI TAKAHIRO
IPC: C09D11/00
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a reaction method which can make a solid substance react efficiently in mild conditions with discoloration controlled. SOLUTION: A solid substance to be reacted and a chemical substance which can react with the solid substance are reacted while the solid substance is being pulverized. The pulverization and reaction of the solid substance is done by a process in which the solid substance and the chemical substance are mixed in a container 4 containing balls 13, and the container 4 is revolved to impact on the solid substance. By this operation, the solid substance is pulverized to increase its specific surface area, to prevent the aggregation of the solid substance by the impact, and to improve the efficiency of the reaction. Since the solid substance can be reacted without being heated in the reaction method, the reaction proceeds under mild conditions, controlling discoloration, or the like.

Title: Luminous element with optical fiber
Inventor: SERIZAWA AKIYUKI
IPC: G02B6/42
Filed: 1978-03-06
Abstract: PURPOSE: To reduce the signal noise caused by the reflection on the element surface by providing the luminous surface tilted against the central axis of the optical fiber when the luminous surface of the luminous element is made to touch the end part of the optical fiber.  
     CONSTITUTION: The normal lines are not set in parallel between central axis 15 of optical fiber 14 and luminous surface 17 of luminous element 16 but made to touch each other with angle of α. And material 18 featuring the same refractive index as the core of fiber 14 is filled onto the coupled surface. As a result, light 19 propagated within fiber 14 is partially reflected by surface 17 to become light 20. As propagation angle θ 1  of light 20 is large within fiber 14, the light does not propagate within fiber 14 but radiated to outside fiber 14 through the clad. In this connection, angle α formed by axis 15 and surface 17 is set larger than the maximum incident angle determined by the aperture number of fiber 14. Thus, all reflected light 20 are radiated outside fiber 14, eliminating the signal noise completely.

Abstract: PURPOSE:To locate and stop a moving part such as a wrist of a robot to an optional command position with high accuracy, even in case of driving a fluid by air pressure, oil pressure, etc., by controlling a solenoid valve for forward turn, reverse turn and deceleration. CONSTITUTION:At every prescribed rotational frequency of an air motor which is not shown in the figure, pulse signals PA, PB are outputted from magnetic sensors 8a, 8b of a sense part 101, and are inputted to a pulse processing circuit 104. A present position counter 105 counts a rotary pulse RP reversibly in accordance with ''1'' and ''0'' of a forward and reverse turn signal NRS from the circuit 104. As a result, contents of the counter 105 show a present position alphaa of a neck of a robot which is not in the figure, and when a difference between said position and a command position alphac becomes equal to the first numerical value, a comparator 108 outputs a control signal DEV for driving a deceleration value, and decelerates the air motor. Subsequently, when said difference decreases and becomes equal to the second numerical value n2, the comparator 108 outputs both a control signal CCWV' for driving the reverse turn and a control signal BRK' for driving a brake, and stops the air motor.
