Title: Data processing system for power line
Inventor: MAEDA KOUJI
IPC: H02H3/40
Filed: 1978-05-18
Abstract: PURPOSE: To raise the speed of processing, by multiplying present source data containing second higher harmonics by cos(π/4) and 90°-preceding source data by sin(π/4) to extract only the basic wave components from the source data.  
     CONSTITUTION: When a reference electric quantity P(t) is applied to an input terminal 1, a 90°-delayed reference electric quantity p(t-3h) is picked out from a memory 2 and a 180°-delayed reference electric quantity p(t-6h) is picked out from a memory 4. As a result, reference electric quantities are picked out from addition circuits 3, 5 of circuits 6a, 6b. Multiplier circuits 8, 9 perform multiplications. A final calculation result {p(t)+p(1-3h)}{q(t)+q(1-3h)}+{p(t-3h)+ p(t-6h)}{q(t-3h)+q(t-6h)} is obtained from a terminal 11, namely, data  removed of the second higher harmonics are obtained from the terminal 11.

Title: Tension controller
Inventor: FUKUI YASUHITO
IPC: G11B15/43
Filed: 1990-03-12
Abstract: PURPOSE:To suppress the increment of tension applied to a tape due to the increment of an axial load on a reel by adding torque equivalent to the axial load obtained by an arithmetic operation from the output of a reel winding diameter calculator in the feed direction of the tape, and driving the reel. CONSTITUTION:The rotational cycle of the reel 3 is detected by a cycle detector 41, and it is converted to rotational cycle information for the reel 3 by a cycle converter 42. A winding diameter detector 5 performs the multiplication of the rotational cycle information by a prescribed constant since the tape 1 is fed at prescribed speed, and outputs a result as a value proportional to the radius of the reel 3. An axial load calculator 6 performs the division of the prescribed constant by the output of the winding diameter calculator 5, and outputs the result as the torque equivalent to the axial load. A reel driving device 7 drives the reel 3 in the feed direction of the tape 1 corresponding to the output of the axial load calculator 6 equivalent to the axial load, which negates the axial load. In such a way, it is possible to suppress the increment of the tension applied to the tape 1.

Title: Electrophotographic device
Inventor: ANZAI MASAYASU
IPC: G03G15/22
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To make a high speed recording possible without enlarging the drum diameter of a photoreceptor, by making the traveling time of the photoreceptor from a disposing position to first and second developing rollers correspond to the photoresponding time of the photoreceptor. SOLUTION: This device allows the traveling time of the photoreceptor drum 1 from the exposing position by laser beams 3 to a gap between first and second developing rollers 61 an 62 (angle θ) to correspond to the photoresponding time of the photoreceptor drum 1. For instance, by adopting the drum 1, whose photoresponding time is long, and making the range from the exposing position of the laser beam 3 to the first developing roller 61 possible to be set short, a high speed small size recording device is realized. That is, the time from the exposure to the gap between the developing roller 61 and the developing roller 62 (angle θ) is made to be the photo-responding time (tr). Particularly, it is preferable to make the θ to correspond to the tr at the low temp. time.  Namely, since the first developing roller 61 can be brought close to the exposing part, it is very effective when using a system combining the photoreceptor drum 1 with a short diameter and two developing rollers 61 and 62 at higher speed.

Abstract: PURPOSE: To improve press workability by specifying the coating material compsns., film thicknesses and coating weights of respective layers of a surface treated steel sheet formed with coating films in order of a first chemical conversion coating layer, lubricating layer consisting of a second water-base lubricative coating material and a third surface lubricative film layer. CONSTITUTION: The chemical conversion coating layer 3 consisting of a chromate film of a Cr coating weight of 5 to 100mg/m<2> or phosphate film of a coating weight of 0.2 to 2.0/m<2> is formed on the front surface of a plated steel sheet. A water-based lubricative coating material contg. 10 to 30 polyolefin wax and 10 to 40 silica having a grain size of 3 to 30nm is applied and baked thereon at 50 to 85wt.% (hereafter the same) of the total solid content of the sum total of an ether ester type urethane resin and an epoxy resin and the lubricative coating layer 4 is then formed. The lubricative layer thus formed has a thickness of 0.3 to 5μm and the lubricant 5 is dispersed at a particle concn. of 10 to 30%. Further, the surface lubricative coating layer 6 is formed at a thickness of 0.04 to 1μm.  As a result, the lubricative layer of the surface prevents direct contact of the resins and metal molds and the particles dispersed in the film are supplied as lubricants from the inside of the film at the time of working and, therefore, press workability is improved.

Abstract: PURPOSE:To completely recover toner by impressing the 3rd voltage to a recording electrode under the status that image exposure based upon an image exposing means is not executed to recover a toner image on a photosensitive body to a magnetic brush developing machine side. CONSTITUTION:When a device error such as paper jam is generated in image transfer, a toner image 31 is left on a photosensitive film 21. The toner image 31 should be removed as an unnecessary toner image without being transferred to recording paper 32. Thereby the toner image 31 is recovered to a developing machine 23 similarly to the recovery of residual toner 38, but under the status that voltage 27 at the formation of the image is impressed to a recording electrode 25, much toner is stuck as compared to the residual toner 38, the effect of a destaticizing lamp is also reduced and it is difficult to recover the toner image 31. Therefore a voltage change-over switch is connected to the earth to recover the toner. Consequently, reverse electrostatic charge is injected into the toner image 31 and the toner image 31 can be almost completely recovered.

CONSTITUTION:The output voltage V2 of a function generator 17 is lowered at a constant speed by applying a stop signal STP, thereby sequentially decelerating a motor 11. The counterelectromotive force of the motor 11 is presented between lines 12a and 12b through diodes 10a-10f, and when the difference between the output voltage Va of the chopper 2 and the voltage V2 becomes larger than the output voltage V4 of a vias voltage setter 33, a transistor 14 is turned ON by a comparator 31, and the counterelectromotive force is consumed by a resistor 13. The motor 11 is decelerated by the induction generative brake, the voltage Va is switched so as to becomes smaller than the output voltage V5 of a switch voltage setter 37. Then, a timer 21 outputs a signal by the comparator 35 and an AND circuit 38. In this manner, a 3-phase distributor 20 continuously turns ON only transistors 9a, 9f, thereby DC braking the motor 11.
