Title: Static reactive power compensation equipment
Inventor: YOSHITAKE HIDEKI
IPC: H02J3/18
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a conventional second transformer for thyristor current detection and an interface circuit, to simplify whole constitution, to secure the dominance in terms of cost, and to improve the reliability, by detecting a fault of a main circuit from the output of the input current detection transformer of a static reactive power compensation equipment. SOLUTION: The voltage of a distribution line or a transmission line is detected as a feedback signal through a transformer 7 in a regular operation state. A first control means 12 executes voltage constant control. Faults of a thyristor 5 and a thyristor ignition means 13 are judged in parallel to regular operation. The method is to detect whether the input current of the main circuit 6, which is detected in a first transformer 8, is unbalanced or not, in an unbalance detection means 9 and to judge the faults of the thyristor 5 and the thyristor ignition means 13 by the first judgment means 10 from the result. When the fault is detected as the result, a second control means 11 opens an opening/ closing means 2 and detaches the static invalid power compensation device from the distribution line or the transmission line 1.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device in which clear high-speed and multi-color printing can be realized in a compact device by increasing the rotation number of developing rolls in developing machines in the second development and on to be larger than a standard /rotation number. SOLUTION: A first developing machine 4 applied to the black color and a second developing machine applied to chromatic colors are disposed around a photoreceptor 1. In the case where the number of printing pages having a printing rate of an image for the second color and on at a specified printing rate or less exceeds a specified page number, a rotation number of developing rolls of applicable developing means 4, 5 for the second development and on is increased by 10-40%, or more favorably by 15-30%, the standard rotation number by a rotation number control means 46. This means that the rotation number of the developing roll 40 is increased to increase quantity of insulation toner, while discharge of mixed toner included in development toner can be simultaneously accelerated.  In the case where the number of the printing pages of a specified printing density or less exceeds the specified page number, therefore, mixing of colors is not increased.

Title: Method for treating medical polymer molding by irradiation with electron beam
Inventor: WASHIO MASAKAZU
IPC: C08J7/00
Filed: 1990-07-27
Abstract: PURPOSE:To polymerize a residual monomer in a polymer molding and simulta neously sterilize the molding safely by irradiating it with electron beams to give it a specified amt. of energy. CONSTITUTION:A medical polymer molding which is produced from a polymer material, such as a polystyrene, contg. an unreacted monomer (e.g., an artificial organ, a catheter, a sewing thread, or a blood bag) or a package of the molding is irradiated with electron beams in such a way that the molding or package is given an energy of 2.5-30Mrad. Thus, the unreacted monomer polymerizes to increase the mechanical strengths of the molding, enabling the production, from a cheap polymer (e.g., a PS), of it having qualities comparable with those of one produced from a high-quality polymer (e.g., a PP). Simultaneously, the molding is sterilized without using a sterilizing gas, eliminating fear of cancinogenicity due to the remaining gas.

Title: Drum shear
Inventor: UEDA TARUO
IPC: B23D25/12
Filed: 1981-12-09
Abstract: PURPOSE:To improve the shearing performance by placing a required member at the outside of a distribution gear secured to upper and lower drums then restricting the distance between the centers of both gears to the narrowing direction. CONSTITUTION:Discs 9, 10 having the diameter same as that of the pitch circle of distribution gears 5, 6 are secured to the outside of distribution gears 5, 5 and 6, 6. When the gears 5 and 6 are geared in the proper state, the circumferential end faces of both discs 9, 10 will contact each other. The radial reaction forces produced on the gears 5, 6 at the cutting of a material are shared by both discs 9, 10 and since the additional resistance due to this reaction force is only the rolling friction between both discs 9, 10, the driving force to be transmitted to the drum 1 can be used effectively for the cutting of the material.

Title: Switching power supply
Inventor: SAKAI HIROSUKE
IPC: H02M3/28
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to use the switching power supply both on a commercial alternating-current power supply and on a battery for automobiles, by installing an intermediate tap on the primary side of a transformer, and, if an input voltage is low, automatically connecting the input voltage to the intermediate tap on the primary side of the transformer. SOLUTION: A commercial alternating-current power supply input through an AC plug 1 is rectified through bridge rectifier circuits 2, 3, 4, 5, and the value for the obtained direct-current voltage is judged through a voltage judging circuit 7. According to the output of the voltage judging circuit 7, the output of the bridge rectifier circuits 2, 3, 4, 5 is switched to the intermediate tap on the primary winding of a transformer 9 through a switch 8. The primary-side current is turned on and off by a transistor 10 to obtain a desired secondary-side output voltage. When a battery for automobiles, for example, is used, the AC plug 1 is connected to the cigar lighter socket in an automobile or the like through a trunk connector 17. As a result, one and the same switching power supply can be used both on a commercial alternating-current power supply and on a battery for automobiles.
