Title: Polishing method
Inventor: NAKASUGI MIKIO
IPC: B24B13/00
Filed: 1987-03-19
Abstract: PURPOSE:To enable provision of high efficiency and excellent surface precision even when a small part is polished, by a method wherein a magnetic force is exerted from the workpiece side, and polishing is effected in a state a polishing tool is pressed against the workpiece as a magnetic polishing agent is attracted to the desired part of a workpiece surface. CONSTITUTION:Since a roller 26 and a roller 30 are rotationally driven by a drive means, and a workpiece 2 supported by a support body 4 is relatively moved in a desired mode to a tool 50 to perform polishing. In this case, the resistance value of a variable resistor 22 of the drive part is set, and a switch 24 is brought into an ON-state. A control circuit 44 outputs a command signal, by means of which rollers 10 and 14 are rotated, to an x-drive circuit 36 and a y-driven circuit 38 so that the position of an electromagnet 6 is normally constantly maintained. Since the electromagnet 6 is normally positioned right below a polishing tool 52, magnetic flux density of a magnetic field generated on the surface of the workpiece 2 is maximized on a polishing tool position. Thus, a magnetic polishing agent is normally attracted between the polishing tool and the workpiece, and the polishing agent is prevented from running out, and polishing is effected with high polishing efficiency.

Title: Video signal processor
Inventor: ITO TETSUYA
IPC: H04N9/09
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a processor capable of processing even at high sampling frequency and securing wide bands by performing double speed clock processing in the case of low sampling rate by generating Y signals on a base band through equivalent double speed processing for performing parallel processing. SOLUTION: R, G and B signals from an image processing part 1 are supplied to a Y signal generating circuit 2 and the Y signals are generated by equivalent double speed processing. At the Y signal generating circuit 2, luminance signals Y (0) and Y (π) of two systems are generated by mutually shifting the 0 and πphases of three R, G and B signals. When the sampling rate is high, for example, the signal band is limited by an LPF 6 and a 1st signal system 8 is used as the base band. When dealing with signals at low sampling rate, on the other hand, the generated luminance signals Y (0) and Y (π) are multiplexed by a multiplexer 3 having a double speed clock, and a 2nd signal system 7 are used for doubling the band of signals.

Title: Control rod for pressurized water reactor
Inventor: KIYAMA YOICHI
IPC: G21C7/117
Filed: 1988-03-16
Abstract: PURPOSE:To prevent the crack of the stainless steel cladding pipe of a control rod by internal pressurization of only the lower part by coating the outside surface of the upper cladding pipe with Cr, etc., to impart wear resistance thereto and subjecting the lower part to internal pressurization and reducing the outside diameter of an absorber, thereby increasing the gap from the cladding pipe. CONSTITUTION:Of the respective parts of the control rod, the part where the problem of friction arises is upper than about 350mm from below where the contact with the guide guard of the control rod arises and the crack of the cladding pipe arises up to about 300mm from below. The control rod is, therefore, made into a piece of the rod formed by coupling two independent parts by an intermediate end plug 13. The upper and lower parts are respectively non-pressurized and pressurized. Further, the gap between the absorber 15 and the lower cladding pipe 14 is taken large by reducing the outside diameter of the lower absorber 15. Then, the absorber and the pipe do not come into contact with each other before the end of the life and tensile strains are not longer generated in the control rod 4. The wear resistance is improved by coating Cr, etc., on the outside surface of the upper cladding pipe 11.

Title: Lithium secondary battery
Inventor: NAGAI TATSU
IPC: H01M4/58
Filed: 1986-03-20
Abstract: PURPOSE:To prevent increase in internal resistance or bulging caused by discharge and to increase charge-discharge cycle performance by using a mixture of titanium disulfide, lithium, and gelled organic electrolyte in a positive electrode. CONSTITUTION:A mixture of titanium disulfide, lithium, and a gelled organic electrolyte is used in a positive electrode. This positive electrode is formed in such a way that titanium disulfide, lithium, and gelled organic electrolyte are mixed to make titanium disulfide to gradually react with lithium in the existence of gelled organic electrolyte, and lithium is penetrated between the layers in the crystal structure of titanium disulfide, and the solvent such as propylene carbonate is also penetrated between the layers of titanium disulfide. In a battery using this positive electrode, the space between the crystals of titanium disulfide is saturated to prevent the penetration of solvent into the positive electrode in battery reaction. Thereby, decrease in the effective amount of electrolyte is prevented to prevent increase in internal resistance and deterioration in charge-discharge cycle performance. The swelling of the positive electrode caused by the battery reaction is prevented to suppress the bulging of the battery.

Title: Floating wave dissipating bank
Inventor: NONAKA RIYOUICHI
IPC: E02B3/06
Filed: 1981-04-25
Abstract: PURPOSE:To dissipate waves by breaking a phase of waves, by mounting a parapet to a top of a floating body, having a triangle section, and along a longitudinal direction. CONSTITUTION:In case a floating body 1 is moored, mooring members 4 are attached to a front and a rear hook part 3, and are attached in the shape of ?  to weights 5. The advancing waves run on a slope at the front side of the floating body 1, but can not keep on a phase up to the surface of the sea at the rear part because of a slope. The waves come downward with a somewhat time lag, and as a result, a sharp difference in phase is produced between the front and the rear of the floating body 1, which results in effectuating wave dissipation. Additionally, a parapet 2 prevents waves from riding over the floating body 1, which results in improving a wave dissipating effect.

Inventor: KASHIWARA YUKIO
IPC: G01R21/06
Filed: 1984-03-30
Abstract: PURPOSE:To hold the current conversion efficiency of a current transformer invariably constant and to take a high-precision measurement of weight by demagnetizing the current transformer automatically evey time a power source is turned on. CONSTITUTION:When a power source switch is turned on, a switch 9 is placed at the side of a contact (a) synchronously for a specific time. At the same time, a signal generating circuit 10 outputs an AC signal which has an enough amplitude for magnetic saturation and varies in amplitude to zero with time. This AC signal flows through secondary coils of respective current transformers CT1 and CT2 and cores of those current transformers return to operation points in initial states a certain time later and are demagnetized automatically. The switch 9 is connected to a contact (b) a specific time after a switch 8 is turned on, and the secondary coils of the current transformers CT1 and CT2 are connected to sides of a multiplier 4 to measure electric power. Therefore, the operation points of the current transformers CT1 and CT2 return to the initial states, so the current conversion efficiency is at an initial constant value and the electric power is measured with high precision.
