Title: Input protecting device
Inventor: AOKI KAZUMICHI
IPC: H03F1/42
Filed: 1982-04-13
Abstract: PURPOSE:To obtain an input protecting device which has strong electrostatic stress by providing aluminum electrode and conductors on an oxidized film of an N type Si substrate, connecting them to the input terminal of an IC and providing a deep P type layer of low density under the connecting pad. CONSTITUTION:An N<+> type layer 4 and a P<+> type layer 3 are provided on an N type substrate 2, and a deep P type layer 7 is formed under the aluminum electrode 1 on an oxidized film 6 and at the connecting part 5. When a large negative voltage is applied to the electrode 1, a lower N type layer is inverted, the layers 3, 7 are connected, the junction capacity of the layer 7 and the substrate 2 is added, thereby exhibiting large input capacity, and increasing the electrostatic breakdown withstand voltage. The concentration of an electric field at the edge of the electrode which is caused by the inverting phenomenon under the electrode 1 is prevented by providing the layer 7, and the defect in Si due to stress at the junction time does not affect the influence of the electrostatic withstand voltage. According to this structure, an input protecting device which has high reliability can be obtained without adding special steps.

Title: Fuel assembly
Inventor: MORI KAZUMA
IPC: G21C3/30
Filed: 1993-02-26
Abstract: PURPOSE:To reduce radioactivity in a primary coolant by employing an Ni alloy component applied with a metal film on the surface in a fuel assembly. CONSTITUTION:In a fuel assembly 10 for pressurized water reactor, stainless steel components, e.g. upper and lower nozzles 13, 14, and Inconel component, e.g. a supporting grid 12 and a leaf spring 19, are plated with Zn (other than Zn<64>). Consequently, Co impurities are not eluted from alloys containing Ni into the primary cooling water system during operation of nuclear reactor and growth of radioactive scale is restrained thus reducing the exposure of a worker to radioactivity at the time of inspection of nuclear reactor. Even if Co is thermally eluted during the operation of nuclear reactor, elution of Zn prevails to block the elution of radioactive Co thus blocking the deposition of scale.

Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To turn a video signal, for which an effective scanning line number 516 of multiple subnyquist sampling encoding(MUSE) signal is converted to an effective scanning line number 485 of national television system committee(NTSC) signal by a MUSE/NTSC converter, into signal for displaying a correct image even on display equipment having no video validity signal. SOLUTION: Through interpolating processing of 16 scanning lines due to a 15/16 vertical compressing circuit 10, 15 scanning lines to be used after conversion and one scanning line not to be used are prepared, these prepared data are written into a memory 20 by the clock (32.4MHz) of MUSE signals and simultaneously read out of the memory 20 by the clock (28.665MHz) of video signals after conversion, and the data of one scanning line not to be used after conversion are not written in the memory 20 by a control circuit 30. Thus, the correct image can be displayed without cutting the upper and lower limits in the number of effective scanning lines in the MUSE signals and required memory capacity can be reduced without enlarging difference between the time of write to the memory 20 and the time of read.

Title: Magnetic disk and its production
Inventor: TAKASAGO HIDEKAZU
IPC: C09D7/12
Filed: 1983-04-11
Abstract: PURPOSE:To obtain a magnetic disk which can avoid sticking with a magnetic head despite the use of a liquid lubricant. CONSTITUTION:A magnetic medium layer 1 containing a binder 2 and a magnetic matter 3 is unified with an aluminum substrate 4 which underwent the aluminum anodizing treatment to constitute a magnetic disk. Then additives 8 having diameters smaller than the size 6 of a gap formed between the surface of a magnetic disk and the surface of a magnetic head 5 having contact with said magnetic disk are dispersed to the layer 1. The liquid lubricant is kept in the microholes 7 although the head 5 is kept with contact to the magnetic disk owing to the difference of capillarity between the magnetic disk and the magnetic head. Then the pressure and moisture are applied to the lubricant in the hole 7 by the friction between the magnetic disk and the magnetic head when the magnetic disk is actuated. As a result, the lubricant leaks out to the surface of the magnetic disk to perform a lubricant function. Thus the friction can be avoided between the magnetic head and the magnetic disk.

Abstract: PURPOSE:To obtain a magnetic recording medium having superior durability by allowing a Cr-rich layer having a specified compsn. to exist in a magnetic layer within a specified depth range from the surface of the magnetic layer. CONSTITUTION:When a Cr-contg. magnetic recording layer 20 of Co-Cr, Co-Ni-Cr or the like is formed on a substrate 6 to obtain a magnetic recording medium, a Cr-rich layer 30 having 0.3-0.7 ratio of Cr to (Co+Cr) or (Co+Ni+Cr) is allowed to exist in the layer 20 within the depth range of 100Angstrom  from the surface of the layer 20. In case of <0.3 ratio, the hardness of the layer 30 is low. In case of >0.7 ratio, the wear resistance is deteriorated. Thus, a surface layer having high hardness and superior wear resistance can be formed and the mechanical durability of the magnetic recording medium can be improved.
