Title: Information recording medium and information recording device
Inventor: SASA TAKESHI
IPC: H04N1/00
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain an information recording medium having high accuracy in the shape by forming a projecting part provided along the circumferential direction at least on the outer peripheral part corresponding to a projecting part formed along the radial direction. SOLUTION: A data zone consisting of the recessed and projection parts and a servo zone are radially formed respectively on a substrate of a magnetic disk 3, and further an anchor zone is formed on the outermost circumference, then magnetic films are formed on these surfaces. That is, the data zone is concentric and formed so that the data tracks DT thereon are in the projected state. Servo patterns SP are formed in the servo zone. On the anchor zone, an annular anchor pattern AP concentric with the tracks DT is formed to be the projected part.  Since the anchor zone, in which the direction of pattern on the recessed and projection part is the circumferential direction, is thus provided outside the servo pattern, the contraction of a molded substance in the radial direction on the servo zone is controlled by the anchor zone in the case the substrate of the magnetic disk 3 is constituted with a synthetic resin.

Title: Color separation image correcting method
Inventor: KO HIROTETSU
IPC: H04N1/46
Filed: 1987-04-10
Abstract: PURPOSE:To minimize a color correcting error and to improve a color reproducibility by converging gradually from observation color data, calculating a final target value and making this into color data. CONSTITUTION:A reproducing color obtained by the combination of plural basic colors is outputted concerning plural combinations. Next, the value of the color specification system to respective combinations is calculated. The space area of the color specification system including an intermediate color which comes to be a target set in the space formed by the value of the calculated color specification system is successively divided corresponding to the space area of the coordinate system constituted of the basic color and the space area including the intermediate color which comes to be the target is reduced. The space area obtained as the result is operated and the target value of the coordinate system corresponding to the value of the color specification system is obtained. The target value of the coordinates is corrected as the combination of the basic color to reproduce the intermediate color to be obtained. Thus, color separation image information corrected corresponding to the input color separation image information is obtained. By this method, the correcting value is very correct and for that reason, the color reproducibility of the high accuracy can be executed.

Title: Gate turn-off thyristor
Inventor: KOGA TAKEHARU
IPC: H01L29/74
Filed: 1989-04-07
Abstract: PURPOSE:To prevent a reduction in a controllable current at the time of turn- OFF by a method wherein an anode short rate directly under segments in the vicinity of a gate terminal is made lower than an anode short rate directly under other segments and the widths of the segments in the vicinity of the gate terminal are made thinner than the widths of the segments apart from the gate terminal. CONSTITUTION:When insular p-type emitter layers 1 are provided under n-type emitter layer segments 4 through intervals (a) and are surrounded with an N<+> layer (an anode electrode) 7, an anode short rate is defined by a/b if the widths of the layers 1 are assumed to be (b). An anode short rate dependence in a turn-OFF time has a relation that the smaller the short rate a/b becomes, the less a striking current becomes and the turn-OFF time becomes long. Moreover, a segment width dependence in the turn-OFF time has a relation that even if the short rate is reduced for decreasing the striking current, a uniform turn-OFF can be realized within the surface of a gate-turn-OFF thyristor by making narrow the segment width directly over the layer 1 in the vicinity of a gate terminal 10. Thereby, a reduction in a controllable current due to a current concentration at the time of turn-OFF can be prevented.

Abstract: PURPOSE: To obtain a molded product of a constant distribution of thickness in a plug-assist pressure-air forming, by designing a plug in such a manner that, when a plastic sheet is drawn by the plug, the whole surface of the former come into close and uniform contact with an outer surface of the latter.  
     CONSTITUTION: A plastic sheet 17 is drawn by a plug 10 to a terminal insertion position in a female mold 16. A contour of that cross section of the plug 10 which is at right angles to a longitudinal axis 11 thereof and which has the same height 19 as an open end portion 18 of the female mold 16 is in agreement with that of the open end portion 18 of the female mold 16. The size of the contour of the mentioned portion of the plug with respect to the whole circumference thereof is smaller than that of the open end portion 18 of the female mold 16 by a radial distance corresponding to the thickness of the sheet 17. In addition, the diameter of the plug 10 decreases gradually from a rear end portion 15 thereof to a front portion 10-1 thereof. Accordingly, the sheet 17 comes into close and uniform contact with the plug 10. This allows a molded product to have a uniform distribution of thickness.

Abstract: PURPOSE:To produce a mask ROM easily at low cost by a method wherein an oxide film such as thick SiO2 oxide film, etc. is formed on a gate channel between drain and source of EP-ROM or EEP-ROM. CONSTITUTION:A word line of control gate 7 of EP-ROM and a data line of aluminium electrode 8 are respectively impressed with 5V and 2V. Within the ''written'' i.e. ''0'' level status, Vth is made 5V by inpressing data line and word line with 12V while within the ''not-written'' i.e. ''1'' level status, Vth is made 1V. Therefore, within the ''0'' level status, no current is supplied in case of reading whiel within the ''1'' level status, current is supplied. On the other hand, the ''written'' status is constantly maintained in a mask ROM part since the gate channel region between source and drain 2 and 3 is composed of a thick SiO2 oxide film 12. Resultantly EP-ROM and mask ROM are respectively utilized as data ''1'' and ''0'' to form electrosignature codes. Through these procedures, mask ROM may be formed in the same array easily at low cost.

Abstract: PURPOSE:To inhibit leakage currents by electrons and holes generated in a depletion layer by forming an insulating film between a drain region and a high concentration substrate and preventing the formation of the depletion layer extending to the substrate from the bottom of the drain region. CONSTITUTION:Insulating films 20 are shaped at the predetermined positions of a single crystal P-type silicon substrate 18 in high impurity concentration. Polycrystalline silicon 21, 21' are formed onto the insulating films 20. A low- concentration P-type crystal growth region 19 is shaped onto the exposed section of an silicon single crystal on which there is no insulating film 20, and the sections of polycrystalline silicon 21, 21' are used as a source region and a drain region. A gate electrode 23 is formed onto the regions of the polycrystalline silicon 21, 21' through a gate insulating film 22. Since the drain region 21 and the source region 21' shaped from polycrystalline silicon and the high-concentration P-type substrate 18 are isolated by the insulating films 20, a depletion layer extending to the substrate from the bottom of the drain region is not formed, thus inhibiting leakage currents by electron-hole pairs generated in the depletion layer.

Title: Manufacture of photoconductive thin film
Inventor: WADA HIROKO
IPC: H01L31/18
Filed: 1985-04-26
Abstract: PURPOSE:To shorten the optical response time of a light current, by exposing a thin film, whose main component i CdS, CdSe or solid solution of CdS-CdSe to the vapor of InCl3 in the hated state. CONSTITUTION:InCl3 5 is placed on the central bottom part of an alumina-boat main body 1. A glass substrate 3, on which a thin film 4 comprising CdS, CdSe or CdS-CdSe is provided, is placed so as to face upward. A boat cap 2 is mounted. Then the boat is heated. When CdS, CdSe or mixed powder of them 6 is placed in crystal growing, the same result is obtained. It is desirable that the thickness of the film 4 is 2,000-10,000Angstrom  and the heating temperature is set at 450-600 deg.C in this case. In this activation by the vapor of InCl3, the vapor pressure of Cl is lower than that of CdCl2. Therefore, the amount of associated Cl is less and yielded sensitizing centers and various traps become few. As a result, the optical response time is shortened.
