Title: Servomechanism using alternating-current induction motor
Inventor: MIYAJI SHIGERU
IPC: G05D3/12
Filed: 1982-12-30
Abstract: PURPOSE:To minimize an overrun by performing rated rotation drive except in a proximity area and automatic control in the proximity area according to a deviation function, and changing settings of each area easily with high efficiency. CONSTITUTION:An induction motor 1 is driven through a chopping circuit 5 and a rotating-direction control circuit 6 and the opening degree of a valve 3 is varied by its power shaft through a speed reducing mechanism 2. The opening degree of the valve 3 is detected by a current value detector 7 and the deviation (e) of the current value from a command is detected 8. The chopping circuit 5 is controlled on the basis of the deviation (e) through an absolute value amplifier, V/F converter 23, and controller 24. A comparator 25, on the other hand, decides on a forward and a backward rotation. An analog setter 26 sets the range of the proximity range in said control and the range is compared 25 with the deviation; and the automatic control which varies the frequency according to the extent of the deviation in the proximity area or the rated control which locks it and is irrelevant to deviation except in the proximity area is performed.

Title: Image forming device
Inventor: HOKARI NORIO
IPC: G03G21/14
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent generation of scratches and friction between an intermediate transfer body and an image carrier by providing a retracting means to retract the pressed condition of the intermediate transfer body of an endless belt shape against the image carrier, and a control means to control the timing. SOLUTION: A solenoid 53 to retract the pressed condition of a primary transfer roller 24 against a photosensitive drum 20 by pushing down an arm 51, is connected to a free end of the arm 51 to pivotably support the primary transfer roller 24. The solenoid 53 controls the timing to retract the pressed condition of an intermediate transfer belt against the photoreceptor drum 20. In an area with the differential speed between the photoreceptor drum 20 and the intermediate transfer belt, the solenoid 53 is turned on, and the pressed condition of the intermediate transfer belt against the surface of the photoreceptor drum 20 is retracted. Because two members are not brought into slidable contact with each other in the pressed condition, no friction or scratch is generated on the surface of the photoreceptor drum 20 or the intermediate transfer belt.

Title: Character complementing device
Inventor: SUWA MISAKO
IPC: G06Q10/10
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To reproduce the cut part in a more natural form when character images read from a slip or the like overlap with a frame and a part is cut off by complementing a removed part based on the inclination and the width of the line segment of the character image in contact with the frame before.

IPC: B41J2/335
Filed: 1987-09-16
Abstract: PURPOSE:To prevent a reaction with a thermal resistor layer and improve adhesion by forming a lower electrode layer with an Al/Si alloy consisting mainly of Al and at the same time, forming an upper electrode layer with Al. CONSTITUTION:A thermal head is composed of a thermal resistor layer 2 consisting of a composite oxide of barium oxide and ruthenium oxide, a lower electrode layer 3 composed of an Al/Si alloy with Al as a main component, an upper electrode layer 4 of Al and a protective layer 5 of Al2O3, etc., on a substrate 1. Therefore, a reaction with the thermal resistor layer 2 is prevented due to the properties of Al which is a main component of the lower and upper electrode layers. At the same time, the resistance change rate to applied voltage variations reduces, and the adhesion with the thermal resistor layer 2 is increased by the Al/Si alloy. Further, the bonding property is improved by the upper electrode 4 formed by using Al.

IPC: C21C7/10
Filed: 1992-08-31
Abstract: PURPOSE:To efficiently prevent bumping of molten steel by controlling the vacuum degree from starting oxygen-blowing based on a CO reaction energy evaluating index in the inner part of the molten steel given by the ratio of the vacuum degree in the operation to the vacuum degree in the equilibrium. CONSTITUTION:At the time of executing refining by top-blowing the oxygen into the molten steel under reduced pressure, the index X evaluating the CO reaction energy in the inner part of the molten steel is given with the equation X=-6X10<-3>T.lnP/P0 (T: molten steel temp. K) from the ratio P/P0 of the vacuum degree P of the operation tank and the vacuum degree P0 at the equilibrium. The vacuum degree P of the operation is controlled so that this index becomes the specific value, e.g. X <= about 30. Then the vacuum degree during the interval from the starting of oxygen blowing to the confirmation of CO generation is controlled and the index is kept to the reference at the initial stage obtd. from the composition and the temp. of the molten steel. Further, the vacuum degree during the interval to the stopping of oxygen blowing after starting the CO generation is controlled based on the index. By this method, the sudden CO reaction is restrained to prevent the bumping and to avoid the inundation phenomenon of the molten steel.

Title: Method of controlling polarization characteristic of outgoing beam of laser
Inventor: AMAKO ATSUSHI
IPC: H01S3/10
Filed: 1987-09-17
Abstract: PURPOSE:To reduce the intensity variation of diffracted beams by simultaneously turning a lambda/4 wave plate and a polarizing plate around the optical axis of outgoing beams and fixing the lambda/4 wave plate to a laser tube in the intermediate section of an azimuth that the outgoing beam intensity of the polarizing plate is maximized or minimized while removing the polarizing plate from a control system. CONSTITUTION:The magnitude of the variation of the outgoing beam intensity of a laser tube is maximized when the azimuth of polarization P of a polarizing plate coincides with one axis ((x) or (y)). When a lambda/4 wave plate, a crystal axis (x) or (y) of which is displaced at 45 deg. from the azimuth of polarization of the polarizing plate, is mounted between the laser tube and the polarizing plate, output fluctuation is removed. That is, a control system 2 consisting of the lambda/4 wave plate 21 and the polarizing plate 22 is set up on the outgoing side of the laser tube 1, the lambda/4 wave plate 21 and the polarizing plate 22 are turned simultaneously around the optical axis of outgoing beams 11, and the lambda/4 wave plate 21 is fixed to the laser tube 1 in the intermediate section of an azimuth, where the outgoing beam intensity of the polarizing plate is maximized or minimized, while the polarizing plate 22 is gotten rid of from the control system 2, thus reducing the intensity variation of diffracted beams at a time when a random polarizing laser tube and a hologram having large polarization anisotropy are combined to a practicable warrantable extent.
