Title: Capacitor commutation type converter
Inventor: SANO TAKAYOSHI
IPC: H02M7/48
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to keep a level to protect a thyristor from overvoltage low by setting a protection level of a capacitor arrestor to such a one that the sum of double the protection level of the capacitor arrestor and a phase-to-phase peak voltage value of a valve winding may be nearly equal to or lower than the protection level of a valve arrestor. SOLUTION: A protection level of capacitor arrestors 19, 20, 21 is so set that the sum of double the protection level of these capacitor arrestors and a phase-to-phase voltage peak value of a valve winding may be nearly equal to or lower than a protection level of valve arrestors 13-18. When such accidents that may cause an overvoltage condition of capacitors 10-12 that are characteristic to a capacitor commutation type converter occur, the valve arrestors 13-18 do not work. Therefore, a protection level of the valve arrestors can be set at a low value as in an ordinary converter. If the protection level is low, only a small number of thyristors need to be serially connected to thyristor valves 1-6 and thereby the size of the entire equipment can be reduced.

Abstract: PURPOSE:To enable changing a dot pitch and printing letters to a desired printing density by providing a correcting means, which corrects the operation timing of a printing means in the manner of corresponding to the rotation angle of the printing head body. CONSTITUTION:A controller is operated to regulate the rotation angle alpha of a printing head body 1 to obtain a desired printing density.

IPC: B41J2/525
Filed: 1991-09-24
Abstract: PURPOSE:To improve a resistance to physical shock in printing and stabilize a dot shape by a method wherein a color printer expressing a gradation by changing the magnitude of a printed dot is so constructed that colors respectively printed cannot be overlapped with each other. CONSTITUTION:A color printer expressing a gradation by changing the magnitude of a printed dot is so constructed that colors respectively printed cannot be overlapped with each other. For example, when a color image is reproduced with three primary colors Y, M, and C, a printing space 10 corresponding to one pixel is determined for every color on a transfer medium for preventing the respective colors from being overlapped with each other. Namely, when an image including rectangles is to be printed, Y, M, and C are arranged in order in the space 10 for one pixel. After Y is printed, a printing position is shifted by the amount of one dot, and M is printed. Succeedingly, a printing position is shifted by the amount of one dot, and C is printed. In this manner, a resistance to physical shock in printing is improved, a missing of ink is prevented, and a dot shape is stabilized.

Abstract: PURPOSE:To facilitate flattening of the surface of a coating film by rendering the inclination of the side faces of a pattern gentle, utilizing the fact that, in the etching method with acceleration particles, a part of the etched material is readhered to the mask pattern or the material to be etched. CONSTITUTION:An NiFe layer A is superposed on a non-magnetic garnet substrate 1, a photoresist pattern B is provided thereon, and a coating film C of Au having a larger etching rate than the photoresist B is vapor deposited on B at a low temperature so as to prevent the deformation of B. The Au film C and the NiFe layer A are ion trimmed with Ar. In the stage where the film C on the layer A is removed, the material of the film C, Au is readhered on the side faces of the mask pattern B. By further continuing the ion trimming in the vertical direction, the layer A is provided with a pattern AP. When the mask pattern B is removed, the pattern AP has a profile of two steps structure consisting of sections A1 and A2. Since the inclination is made gentle by the presence of the pattern A1, it becomes easy to flatten the surface by applying resin or the like. In such a manner, the pattern is enabled to have side faces inclined by 45-50 deg..
