Inventor: SAKATA TOSHIO
IPC: B24B21/00
Filed: 1981-06-04
Abstract: PURPOSE:To eliminate uneven finish surface roughness on the outside and inside peripheries of a disk by detecting the position of an abrasive head and the rotary angle speed of the disk and by controlling the abrasive linear speed at the outside and inside peripheries of the disk so as to obtain the same speed.

Abstract: PURPOSE:To reduce the unbalance over the entire area of variable and constant voltage areas by so driving means for regulating the inverter output voltage in the variable voltage area and the slip frequency in the constant voltage area that a plurality of inverter output current may coincide with the current command. CONSTITUTION:When both inverters 4, 4' is in multiple pulse mode state, current limiting amplifiers 12, 12' receive common current command IR and the outputs of current detectors 9, 9', and the inverter 4 is controlled in frequency by the sum of the first common slip frequency command FSI and the mean value of the frequencies of two motors. Since the inverter 4' is applied in frequency with the output of a voltage controlled oscillator 19 as a synchronous pulse through a contact 29 to a voltage controlled oscillator 19', it is controlled under the same condition as the inverter 4. In this case since a phase shifter 30 is added thereto and the output pulse of the oscillator 19' is shifted at an electric angle theta, the waveform of the line voltage Vab' at the output of the inverter 4' is shifted at theta/6. In this manner it can reduce the unbalance over the entire area.

Inventor: KUROIWA AKIHIKO
IPC: G11B7/24
Filed: 1981-06-06
Abstract: PURPOSE:To obtain an optical recording medium possible for repeated use with a heat mode, by providing an optical recording layer including light absorbing coloring matter or pigment on a polystyrene base having an average molecular weight within a specific range. CONSTITUTION:An optical recording medium is formed by coating and drying a coating liquid with 0.002-10wt% of a light absorbing coloring matter or pigment (to 1pt.wt polystyrene) to the polystyrene with 350-10,000 average molecular weight on a substrate such as glass and plastic. Pits, 1mu diameter, projected at the circumference, 0.2mu width and recessed at the center are formed at the recording layer by irradiating a He-Ne laser beam on the medium. The bottom of the pits does not reach the bottom of the layer, then the polystyrene and the coloring matter remain, the circumference is smoothed and reading can be made through transmitted or reflected rays through the irradiation of a weak laser beam. Since the uneven pints are molten again through reheating of the medium, erasing is made easy and the use of rewriting can repetitively be made possible.

Title: Method for solidifying coal liquefaction residue
Inventor: IKEDA KOICHI
IPC: C10G1/00
Filed: 1995-04-13
Abstract: PURPOSE: To improve the handleability of a coal liquefaction residue by directly blowing an inert gas at a high speed against a high-temp. liquid residue discharged from a separator to rapidly disperse the residue and simultaneously cool and solidify it to thereby obtain a particulate solid residue. CONSTITUTION: A slurry obtained by mixing coal and a catalyst with a solvent for liquefaction is fed to a liquefaction tower, into which H2 gas introduced at a high temp. and a high pressure to perform hydrocracking of the coal. In the subsequent separation step, the resulted liquefaction product is separated into a gas, water, a light oil a medium oil, and a mixture of a heavy oil to be circulated and a residue having a softening point of about 160-200 deg.C. The heavy oil is then separated from the residue by vacuum distillation at about 300 deg.C, while a liquid residue regulated so as to have a temp. higher than its softening point by at least 100 deg.C is continuously discharged from the tower bottom.  An inert gas, e.g N2 , is directly blown against the liquid residue at a given rate (gas/residue ratio) to cool the residue to a temp. lower than its softening point by at least 130 deg.C. Thus, a particulate solid residue is obtained.

IPC: G06K9/38
Filed: 1995-03-20
Abstract: PURPOSE: To precisely perform pattern recognition even when a body to be recognized differs in lightness with areas by performing both correlating operation for detecting a lightness distribution and correlating operation for detecting a pattern to be recognized through two correlative optical systems. CONSTITUTION: This device is equipped with a double image formation systems 10 facing a body A to be inspected, and the correlating optical systems 20 and 30 are arranged behind the system 10 across a spatial optical modulator 40. The optical system 20 performs the correlating operation for detecting the lightness distribution of the body A to be inspected and the other optical system 30 performs the correlating operation for detecting the pattern to be recognized on the body A to be inspected. The lightness distributions of obtained correlative images are inverted by a correlative image inversion optical system 50 and put together. A threshold process is performed for the composite image to select only peaks which exceeds the threshold value, and the clear peaks are obtained.  Those peaks accurately reflect the correlation to the pattern to be recognized irrelevantly to differences of the lightness distribution between the input images.
