Title: Semiconductor device and manufacture thereof
Inventor: MIZUO SHIYOUICHI
IPC: H01L21/8229
Filed: 1984-01-25
Abstract: PURPOSE:To reduce the series resistance of a Schottky diode (SBD) and to suppress the irregular resistance by employing a structure that the density increases from the surface to an N<+> type buried layr for the SBD of an LSI. CONSTITUTION:In the drawing of the density distribution of depthwise direction of the SBD, 9 is the density distribution of the SBD diffused layer of the case that P<+> is implanted by the conventional method, and 10 is that of the case that formed by this method. A low density layer is not formed between a SBD diffused layer 10 and an N<+> type buried layer 6, and the resistance may be suppressed to low value. The density gradient of the layer 10 at the connecting portion of the layer 10 with the layer 6 is mostly eliminated and reduced. Thus, the variation in the resistance due to the variation in the thickness of an epitaxially grown film can be suppressed to small value. The layers 9, 10 have the same surface density, and the same forward voltage VF is applied, but the quantity of implanting phsophorus per unit area of the case of the layer 10 is increased. Since the surface density of the SBD diffused layer is suppressed to low value as compared with the maximum density of the diffused layer, ion implanted amount can be increased with respect to the constant VF, thereby reducing the series resistance of the SBD.

Abstract: PURPOSE:To reduce the equipment cost by providing an object value generating means, a variable oscillation control means, a variable amplitude control means and a phase feedback control means in the equipment to control the variable amplitude control means corresponding to an amplitude object level and an amplitude error. CONSTITUTION:An analog phase object signal outputted from an object generating circuit 41, an output of a 1st detector 48, an output of a 2nd detector 52 and an output of a down-convert mixer 50 are fed to a phase comparator 49.

IPC: G06F12/00
Filed: 1991-01-31
Abstract: PURPOSE:To attain the effective use of an image data storing area of an optical disk by rewriting the retrieving information on an optical disk and also rewriting the index data on the optical disk based on the rewritten retrieving information when an updating request is received for the retrieving information. CONSTITUTION:When a changing request is inputted through a keyboard 6 for the retrieving information on a designated document, this information is read out of an optical disk 12. Then the key word and the document number written into the retrieving information are deleted out of the index data generated in an auxiliary storage 4. Then the retrieving information on the corresponding document written on the optical disk is rewritten based on the inputted changed retrieving information. Based on this rewritten date, the index data stored in the storage 4 is updated. Then the data recorded on the disk 12 are rewritten based on the updated index data. Thus the image data storing area of the disk 12 is effectively used.

Title: Magneto-optical disk and its manufacture
Inventor: SATOBI YUUICHI
IPC: G11B11/10
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To diminish noise from the groove by forming a magneto-optical film having a magneto-optical effect, on a disk substrate on which grooves are formed along recording tracks, giving the edge of the groove a curved surface, reducing the radius of curvature of the edge part to a specific value or less, and thereby making disturbance hard to emerge in the magnetizing direction of the magneto-optical film formed on the curved surface. SOLUTION: If an angle is sharply changes at a boundary between the land 6 and the slope 7 (edge 8 on the land side) or between the groove 5 and the slope 7 (edge 9 on the groove side) of a disk substrate 2, the magnetic anisotropy of a magneto-optical film formed on the boundaries is disturbed, inducing disturbance also in the magnetic anisotropy of the film formed on the slope 7, with the disturbed magnetization giving rise to Kerr effect to cause noise. Under the circumstances, the radius of curvature R1 , R2 is designed to be 20 nm or more at the edge 8, 9 on the land and the groove side respectively. As a result, noise is reduced, enabling a high C/N to be obtained.

Title: Solid electrolyte
Inventor: KUDO TETSUICHI
IPC: H01M8/10
Filed: 1985-01-25
Abstract: PURPOSE:To facilitate production of a solid electrolyte which can be easily molded by using a heteropoly-acid containing carbon as the hetero atom as the main component. CONSTITUTION:The solid electrolyte of this invention is principally composed of heteropoly tungstic acid or heteropolymolybdenic acid containing carbon as the hetero atom. For example, 100ml of 15% aqueous H2O2 solution is added to 16g of tungsten carbide powder (WC) and then after the amount of gas generation reduces 5ml of 3% H2O2 is added. The above operation is repeated five times and then the resulting mixture is left at room temperature to dissolve WC thereby preparing a pale-yellow acidic solution. Next, after soot-like carbon in the solution is filtered off, excess H2O2 contained in the solution is decomposed by the use of a platinized platinum net. The thus obtained original solution for a solid electrolyte is then put in a glass case having a flat bottom and heated until immediately before the solution is solidified. After that, the almost solidified solution is left at room temperature for at least 24hr, thereby obtaining a glass-like flat plate of a heteropoly-acid.
