Title: Manufacture of permanent magnetic powder containing rare earth element
Inventor: IWAMA YOSHIRO
IPC: B22F9/06
Filed: 1987-10-30
Abstract: PURPOSE:To improve magnetic properties such as coercive force and squareness ratio with reduced contamination such as oxidation and corrosion or grain boundary damage by obtaining a ribbon-shaped or flaked alloy thin band by subjecting a molten alloy arranged to a predetermined chemical composition to a liquid quenching, and then applying a hydrogen embrittlement treatment. CONSTITUTION:Liquid bath of a permanent magnet alloy whose composition is Nd15Fe77B6 is prepared in a radio frequency melting furnace, such liquid bath of alloy is made into a thin band by means of a liquid quenching in which it is made to flow down from a nozzle onto a single roll surface rotating at a high speed in an argon atmosphere, a magnetic powder being obtained by a hydrogen embrittlement treatment and a mechanical granulation treatment. The hydrogen embrittlement treatment is made by storing the alloy thin band in a treatment chamber 1, evaporating the chamber by a rotary pump 2, replacing it by Ar gas and then changing to a hydrogen gas source to obtain a hydrogen gas atmosphere (H2 100%) whose pressure is 2kg/cm<2>. After 24hours, the treatment chamber 1 is evaporated and maintained for 1hour. Hydrogen gas is introduced again in the treatment chamber 1 to obtain the hydrogen gas atmosphere of 2kg/cm<2>, such atmosphere being maintained for 24hours, evaporated and then maintained for 1hour.

Title: Manufacture of al alloy material for outside plate of non-painted vehicle
Inventor: IKEDA TSUGUMOTO
IPC: B24B1/00
Filed: 1994-11-10
Abstract: PURPOSE: To easily remove stains of the Al alloy material for outside plate of non-painted vehicle by performing the wet type polishing in the condition that the solution at the specified pH exists at the time of finishing the polishing. CONSTITUTION: A plate-like 6063 aluminum Al alloy material is roughly polished, and wet type polishing is performed thereto in the condition that the solution at 2-11 pH exists, and thereafter, and thereafter, it is dried at the ordinary temperature so as to form the oxide film on the surface, and the excellent stain resistant characteristic is thereby obtained. In the case where the solution at 4-9 pH is used for the wet type polishing, the remarkably excellent stain resistance can be obtained. In the case where the solution, of which pH exists out of the range at 2-11, is used for wet type polishing, a trouble that the sudden dissolution is generated for corrosion in the Al alloy material at the time of performing the wet type polishing is generated, and the stain resistance and the cleaning effect are not enough.

IPC: H04N5/238
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To continuously adjust the quantity of light of an optical diaphragm system of the combination of an optical diaphragm and an ND filter by adjusting the aperture diameter of a diaphragm within the range of variable setting value of a diaphragm aperture so that quantity of light which is inputted to a TV camera may continuously change in the range below quantity of light at the lower limit of the diaphragm aperture. SOLUTION: A system controller 19 sets an aperture of an optical diaphragm 65 to a prescribed value based on an input of an operator. If an image that is displayed is not clear, the controller 19 makes the aperture of the diaphragm 65 small, and if the aperture is the minimum value, an ND filter 68b is inserted so that an optical image of the aperture of the diaphragm 65 may be interrupted. The controller 19 performs adjustment so that quantity of light after the filter 68b is inserted can be the same with quantity of light of a minimum diameter of the optical diaphragm before its insertion. If a display image is not clear, the controller 19 makes the aperture of the diaphragm 65 small based on the effect that the operator further converges the aperture.

IPC: H02N2/00
Filed: 1991-09-27
Abstract: PURPOSE:To obtain a piezoelectric actuator which is suitable for positioning a precision instrument by obtaining elliptic motions by producing longitudinal and bending vibrations by the displacement of piezo-electric ceramic plates stuck to the side face of a rod-like metallic piece having a rectangular parallelopiped body. CONSTITUTION:Piezoelectric ceramic plates 11a and 11b and 12a and 12b are respectively stuck to both side faces of a metallic rod 10 having a rectangular parallelopiped body. The length of the metallic rod is decided in accordance with the resonance frequency of longitudinal vibrations and the resonance frequency of bending vibrations or the higher-order resonance frequency of the bending vibrations. The longitudinal vibrations are generated by connecting the ceramic plates 11a and 11b to each other and applying an AC voltage 21 across the plates 11a and 11b and metallic rod. In addition, bending vibrations are generated by connecting the ceramic plates 12a and 12b to each other and applying an AC voltage 22 across the plates 12a and 12b. When a 90 deg. phase difference is produced between the voltages 21 and 22, elliptic motions are produced at the end faces of the metallic rod 10 to which the piezoelectric ceramic plates are not stuck.

Title: Coating applicator
Inventor: ETO YOSHIHIKO
IPC: B05C3/10
Filed: 1987-10-30
Abstract: PURPOSE:To attempt a formation of a uniformly coated layer by forming slopes in the upper edge of a side all of an applicator vessel adjacent to at least one of the inner and outer peripheral faces of the vessel so that any substantially horizontal planes do not exist in the aforementioned upper edge. CONSTITUTION:In case that a body 6 is coated with a coating liquid 3 contained in an applicator vessel 10 by dipping the body 6 into the liquid 3 and then lifting it, the coating liquid 3 is supplied into the vessel from below and allowed to overflow an upper edge 4a of the side wall 4 of the vessel. Slopes 1 and 2, which are adjacent to at least one of the inner and outer peripheral faces, 4b and 4c, of the side wall 4 of the applicator vessel, are formed in the upper edge 4a so that any substantially horizontal planes do not exist in the upper edge 4a. The upper edge 4 becomes, as a result, so wettable that an increase of the amount of coating liquid accompanying a pulsation of a pump is easily allowed to overflow the upper edge so as to prevent vertical movements of a liquid surface. Stepwise unevenness of coating can be prevented, and a uniform coating layer is obtained accordingly.

Filed: 1986-11-20
Abstract: PURPOSE:To attain simple and accurate adjustment of a head switching signal by adjusting a delay time by easy and accurate measurement using a synchronizing signal for track control, and storing the adjusted delay time into a nonvolatile memory. CONSTITUTION:An arithmetic circuit 11 calculates the difference between a preset reference value, i.e., a count data obtained at a proper delay time and a count time, i.e., a fetched count data to calculate the data being a correcting of delay time and outputs a mean value of each calculated data to a memory 6 as a corrected data. Moreover, the storage time of the memory 6 is increased/ decreased by the time of correction value by using the corrected data outputted from the arithmetic circuit 11, the delay time of the memory 6 is corrected into proper delay time and the head switching signal is adjusted automatically. Since the memory 6 is a nonvolatile memory, the delay time at adjustment is always stored after the adjustment and the head switching signal is formed in a proper delay time at all times at the time of applying recording and reproduction afterward.
