Title: Magnetic disc recording and reproducing device
Inventor: FUJIMOTO EISUKE
IPC: G11B5/02
Filed: 1984-06-18
Abstract: PURPOSE:To increase considerably the recording capacity by arranging two read/write gaps at the same azimuth angle in directions opposite to each other and setting the pitch to an odd-fold length of the gap width and setting the movement unit to the two-fold length of the gap width. CONSTITUTION:Read/write gaps 11a and 11b of a magnetic head 11 are arranged at the same azimuth angle theta in directions opposite to each other with respect to the X direction. The pitch of gaps 11a and 11b is set to an odd-fold (the three- fold) length of a gap width W, and a movement pitch P1 of a gimbals 4C in the X direction is set to the two-fold length of the gap width W. Thus, since the azimuth recording system is adopted, guard bands for crosstalk prevention are unnecessary, and the storage capacity is considerably increased to the 1.7-fold value of a conventional storage capacity.

Title: Measuring method for moisture content in organic solvent
Inventor: NAKAMURA YOSUKE
IPC: G01N9/00
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to measure a moisture content safely and quickly by a method wherein the moisture content is found by using a correlation expression between the measured value of an organic solvent measured by using a vibration-type density hydrometer, a moisture content, in an organic solvent, measured in advance and a density measured by a vibration-type density hydrometer.

The moisture concentration of the organic solvent in every additon is found. At the same time, the organic solvent is introduced into a glass cell. The density of the organic solvent is measured by a vibration- type density hydrometer. Thereby, a correlation expression between a moisture content in the organic solvent and its density is created. Then, the density of the organic solvent as the object to be measured is measured by a vibration- type density hydrometer.

Abstract: PURPOSE:To prevent a cassette loading mechanism and a tape loading mechanism from being damaged due to erroneous insertion of a cassette by controlling their operations with a relative positioning change in the vertical direction between a cassette drawing lever and a cassette detecting lever that occurs at the time of engaging the cassette drawing lever with an operational recessed part on the upper surface of the cassette. CONSTITUTION:A drive for the cassette loading mechanism is fitted to a slide angle 11, which is turnably fitted with the cassette drawing lever 9, to be adjacent to the cassette detecting lever 10, and is controlled by utilizing the relative positioning change in the vertical direction between the cassette drawing lever 9 and the cassette detecting lever 10 that occurs at the time of engaging the cassette drawing lever 9 with the operational recessed part 58 on the upper surface of the cassette. Consequently, even when the cassette 1 is inserted into an insertion hole until a panel surface by erroneous insertion, the cassette drawing lever 9 is not engaged with the operational recessed part 58 on the upper surface of the cassette at all. By this method, the cassette loading mechanism to be driven is not operated by the relative movement between the cassette drawing lever 9 and the cassette detecting lever 10, thus preventing the mechanism from being damaged.

Abstract: PURPOSE:To discriminate the presence or absence of a corrosion preventive plating on line by maintaining the specified distance between the probe of a sensor and the surface of a steel sheet by means of a jig in contact with the steel sheet and discriminating the quantity of electricity inputted to a controller. CONSTITUTION:The positioning jig 2 is screwed to the outer periphery of the prove 1a of the sensor 1. The jig 2 maintains the specified distance between the probe 1a and the outside surface of the steel sheet when the jig 2 is pressed to the outside surface of the steel sheet W by regulating the amt. of screwing of the probe 1a. The signal of the sensor 1 is fetched in the controller 4. The controller 4 is constituted as a microcomputer to divide the change in the output of the quantity of electricity of the sensor 1 varying with the presence or absence of the corrosion preventive layer formed on the surface of the steel sheet W and the fluctuation in the thickness thereof to plural regions of a specified width and to determine the discrimination signal corresponding to the respective regions. The region between the region where there is the corrosion preventive layer and the region where there is no corrosion preventive layer is previously determined as the region where the discrimination is infeasible. The erroneous detection of the presence of absence of the corrosion preventive layer is prevented in this way.
