Title: Optical disk medium and its production and optical disk system
Inventor: KUDO JUNICHIRO
IPC: G11B11/10
Filed: 1992-05-15
Abstract: PURPOSE:To prevent undesired vibration and to stably execute recording and reproducing at all times by working a protective layer in such a manner that the height of the outer peripheral edge of the protective layer attains a prescribed value or below with respect to the flat surface of the protective layer. CONSTITUTION:A recording layer 3 of a magnetic thin film is deposited on a transparent substrate 2 and this recording layer 3 is coated with the protective layer 4, thereby a magneto-optical disk 1 is constituted. The magneto-optical disk blank material is rotated at the time of production of the optical disk and a burnishing tape which travels is brought into sliding contact with the peripheral edge surface thereof, thereby this surface is burnished. As a result, the height h1 of the build-up 4b of the protective layer including the build-up 2b of the substrate with respect to the flat part 4c of the protective layer is specified to 20mum (more preferably <=15mum).

Title: Digital ground-fault distance relay
Inventor: MAEDA TAKAFUMI
IPC: H02H3/40
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a reactance measuring error even when the ratio of the actual resistance portion of the line constant of a transmission line to the reactance of the line is different, by calculating the voltage drop from an accident point to the installed point of a ground-fault distance relay which occurs due to a one-line ground-fault accident by resolving the voltage drop into the α-component and zero component of its own line and the zero component in other phases. SOLUTION: Six equations are set up including m=kj (j=1-6) as an arbitrary time series, and unknowns Rα , R0 , R0 ', Lα , L0 , and L0 ' are calculated by means of an 8th means 18. An 8a-th means 18A discriminates whether or not the inductance of, for example, an α-component is smaller than a set value by using the value of the unknowns and, when the inductance is smaller than the set value, the means 18A discriminates that operations are conducted and the conventional reactance relay can be realized. Therefore, a digital ground-fault distance relay which can be measured and separated with accuracy even when higher harmonics, etc., are superposed when an accident happens can be realized.

Abstract: PURPOSE:To enhance regeneration effect of a filter and to simplify operation by automatically control in sequence respective operation for operating to discharge a solvent in a filter device into an auxiliary tank, for operating a pressurizing means, and for operating to deliver a solvent in the auxiliary tank and in a tank to the filter device. CONSTITUTION:Valves 8, 27 are opened to transfer a solvent in a filter device 9 into an auxiliary tank 28. Next, valves 10, 64 are opened to drive a pressurizing means 63 to feed pressurized air to a filter in the direction reverse to a flow of the solvent so as to peel off and precipitate stuck soil at a bottom inside the auxiliary tank 28. Then, a valve 29 is opened while valves 27, 64 are closed to drive a solvent pump 7 to return a stored solvent into the filter device 9 again. Since a lead-out port is positioned higher than the bottom part, precipitated soil is not sucked up. Last, the valve 29 is closed while valves 5, 15 are opened to pass the solvent in the tank 1 to the filter device 9. Respective operation is automatically conducted in sequence by a control means.

Title: Toothed belt
Inventor: SHIMIZU MOICHI
IPC: F16G1/28
Filed: 1979-11-19
Abstract: PURPOSE: To prolong the service life of a toothed belt, by coating the tooth surfaces of the belt with a stretched or rolled sheet of synthetic resin.  
     CONSTITUTION: A sheet 7 of synthetic resin stretched or rolled by a factor of 3 or more is coated over the tooth surfaces of a toothed belt 1 which is made of rubber 5 having iron wires 6 buried therein. Such a belt manufactured as above is far more excellent in maintenance of the fold lines than that coated with nonstretched resin sheet. Therefor, it is enabled to prevent separation of the coating layer due to heating during use of the belt and to prolong the service life of the toothed belt. Here, it is preferable from the standpoint of durability and adhesiveness to use polyamide, polyacetal or polyester resins as the material for the coating layer.
