Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To enable stable operation of a constant voltage generator by mitigating the conventional degradation of breakdown voltage of a diode for generating reference voltage and causing the diode to generate a predetermined reference voltage in a stable manner. SOLUTION: In a high-density diffusion area 16 adjacent to a junction of a diode, to cause breakdown on a substrate interior side having less crystal defect, a substrate surface side is set to have a lower density than that of the interior side.

IPC: C25D5/10
Filed: 1991-11-28
Abstract: PURPOSE:To produce a Zn-Ni-based alloy electroplated steel sheet particularly excellent in chipping property at low temp. by applying plating of a prescribed amount on the sheet sprayed with a plating solution after preplating. CONSTITUTION:After usual pretreatment, the Zn-Ni-based alloy electroplating with 1-2g/m<2> is executed. Next, the same plating solution as the plating solution used for the plating is sprayed, and with substantially the same plating solution as the plating solution, the Ni alloy electroplating is executed in a prescribed alloy content and a prescribed stuck amount. Since fine crack generates on the whole surface of the preplating layer after the plating solution is sprayed, the plating solution low in chemically dissolving power, and high in pH is once removed, and a hydroxide is also removed from the surface by roll drawing. Thus, the preplating layer excellent in adhesive with the base steel sheet is formed.

Title: Active matrix display device
Inventor: KOYAMA JUN
IPC: G02F1/1368
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To connect source followers by two pieces parallel to each other and parallel to the advance direction of laser light, by connecting a data holding control signal to plural parallel-connected source followers. SOLUTION: Two kinds of source followers with threshold value voltages different from each other are formed alternately or at every plural pieces for the advance direction of the laser light. In a laser crystallization process, for eliminating an area that the laser light doesn't irradiate, the laser light irradiates so as to overlap a first irradiation area. The, the width of the irradiation of the laser light is made integer number times or nearly integer number times of the width of the source follower. In such a manner, by making the length of the overlapped part of the irradiation area of the laser light the integer number times of the width of the source follower, the source followers with the different irradiation amount of the laser light are oriented regularly in the moving direction of the laser light to be formed.  Thus, dispersion in a characteristic caused by laser irradiation is reduced.
