Title: Constant current control system
Inventor: KISHIMOTO HIROSHI
IPC: G05F1/10
Filed: 1979-11-30
Abstract: PURPOSE: To suppress an influence upon a power reception system below a constant level by increasing a response speed by obtaining a constant current state by exercising stepping switching control over a DC voltage value from a set value to another DC voltage set value by an addition value.  
     CONSTITUTION: Rectifiers 3 and 3' connected to the secondary sides of transformers 2A and 2C are connected in series to constitute DC circuit 10 and generator excitation side controller 9' for adjusting a DC voltage to a constant value is equipped. Then, DC voltage E determined by the sum of output voltages across rectifiers 3 and 3' is adjusted to constant voltage E 1  by exercising excitation control over electric generator 8. Simultaneously, stepped control is exercised to vary DC voltage value E from set value E 1  to DC voltage value E 1 -E 2 +ΔE obtained by adder 107. Thus, the gradient of the DC voltage is set to zero to obtain a constant current state. As a result, the response speed is increased and an influence upon the power reception system can be suppressed below a constant level.

Filed: 1978-12-12
Abstract: PURPOSE: To make the formation of the pointing part easy and minimize the loss of weight of the material by fusion-welding a shaft material of a small diameter to the end face of the material to be drawn and pressing the fusion-welded part thereby gradually increasing its diameter toward the material to be drawn.  
     CONSTITUTION: A shaft material 12 of a diameter smaller than the outside diameter of a round bar 11 or the like is butted to one end face of the material to be drawn, such as round bar 11, and is fusion-welded. At the same time, it is pressed so that the diameter of the fusion-welded part 13 becomes gradually larger toward the round bar 11. This shaft material 12 is of about the length adding a gripping margin to the width size of a die. By this method, the fusion-welded part 13 becomes conical form convenient for drawing. In addition, inexpensive materials may be used for the pointing shaft material 12 and further the loss of weight owing to cutting of the pointing part is reduced.

Title: Multi-address communication system
Inventor: UCHIDA WATARU
IPC: H04W4/06
Filed: 1995-06-22
Abstract: PURPOSE: To suppress the occurrence of undesired traffics and to reduce the load on the multi-address communication system. CONSTITUTION: When the multi-address communication is started, both base stations A and B transmit the multi-address instructions via the descending control channels and also transmit the pollings via the descending communication channels respectively. A multi-address reception terminal is included in the zone (A zone) of the station A and not included in the zone (B zone) of the station B. Under such conditions, the multi-address reception terminal of the A zone receives the polling and sends back an answer signal through an ascending communication channel. When an answer signal is detected in a prescribed time after the polling is transmitted, the station A decides that a multi-address reception termial is included in the A zone and transmits the multi-address data.  Meanwhile no answer signal is detected at the station B within a prescribed time after transmission of the pollign and therefore decides that no multi-address reception terminal is included in the B zone. Thus no multi-address data is transmitted from the station B.

Title: Optical beam scanning device
Inventor: NOGUCHI MASARU
IPC: G02B26/12
Filed: 1984-07-26
Abstract: PURPOSE:To miniaturize a device and to realize uniform scanning even when wobbling and deviation may occur to the surface of a polygon mirror by using optical system composed of scanning lens, beam splitter, cylindrical lens, and image forming lens, etc. CONSTITUTION:When a reflecting mirror 6a shifts to the position of 6a' because of wobbling or deviation, the light route moves as shown by dotted line, but light beams is made incident on a scanning lens 5 and are as parallel beams seeing from the direction of main scanning. These parallel beams 10 are made incident on cylindrical lens 7 through 1/4 wavelength board and polarizing beam splitter 3. This lens 7 refracts the beam 10 as if it is emitted from its focal dis- tance 7', and the beam is focused by lens 8 at the one point on the scanning surface 9. Therefore, stable and uniform scanning is obtained in spite of wobbling and deviation of the polyyon mirror, and the device can be miniaturized.
