IPC: G06F3/037
Filed: 1980-09-25
Abstract: PURPOSE:To obtain a stable pulse signal for position detecting, by extracting the raster scan light of a cathode-ray tube in the form of two-divided beams and then extracting the difference between a signal received a photoelectric conversion and the other signal received a photoelectric conversion through the blue and green filters. CONSTITUTION:The raster scan light on a screen of a cathode-ray tube 1 is detected at an end 21 of a photodetecting means 2 and then divided into two beams to be led to other terminals 22 and 23. The light made incident from the end 22 is converted into an analog electric signal through a photoelectric converting circuit 4 to be supplied to a negative terminal of a differential amplifier 6. The incident light from the end 23 is passed through an optical filter 3 of blue and green, and the blue and green beams are converted into the analog electric signals through a photoelectric converting circuit 5 to be supplied to a positive terminal of the amplifier 6. Coincidence is secured between the conversion coefficient of the circuit 4 and that of the circuit 5 including the filter 3. Thus only the red signal is obtained at an output terminal 7 of the amplifier 6; while the blue and green signals are obtained at a terminal 8. Both signals are shaped into the pulselike waveforms and mixed up to obtain a stable position detecting pulse signal regardless of the color of light emitted from the tube 1.

Filed: 1984-06-26
Abstract: PURPOSE:To prevent the output of an abnormal correcting value by inhibiting an input of an arithmetic output to an adder when a subtractor is in borrow state, and bringing the output of the adder to a high level in overflow state. CONSTITUTION:When subtractors 9f, 9h are in borrow state, input inhibition circuits 9n, 9p are activated by the output of borrow detection circuits 9l, 9m and an output from the subtractors 9f, 9h is not inputted to adders 9g, 9i. When the adders 9g, 9i are in overflow state, the output of the overflow detection circuits 9q, 9r activates the high level output circuits 9s, 9t and the output of the adders 9g, 9i is brought all into high level. Thus, the output of the extrapolarion operating circuit is controlled so as to prevent an abnormal convergence correction current from flowing.

Abstract: PURPOSE: To obtain a high-protein fraction in high yield, by sieving crushed defatted soybeans to remove the seed coats, by classifying the crushed under size with a dry air current to separate a fraction under a specific size, which is further ground to separate a fraction of specific size.  
     CONSTITUTION: Defatted soybeans are crushed to give fragments, 70W90% of which have a size of about 800μm or less. The fragments thus obtained are sieved with a 60W1000μm screen to remove the oversize seed coats. The undersize part is then ground into particles, 70W95% of which have a size of 30μm or less to separate a fraction of particle size 25W35μm or less. The resulting powder is further ground to give fine particles, 70W95% of which have a size of 20μm or less, by a fluid energy mill having the functions of rubbing off and finely dividing carbohydrates on the protein bodies. The powder is then classified to give a fraction comprising 80% or more of particles having a size of 5μm or more. Repeated milling and classification operations permit defatted soybean powder with a higher protein content.

CONSTITUTION:When the height (h) of the level of the molten metal 12 in a tundish 2 lowers gradually and arrives at a critical value hc in transferring the molten metal 11 in a ladle 1 into the tundisch 2 and casting the same into a mold for continuous casting from the tundish 2 in the stage of continuous casting of molten steel or  the like, the molten slag on the surface of the molten metal floats and separates insufficiently or further the slag is included in the molten metal cast into the mold, thus  resulting in the decreased cleanliness of a continuously cast ingot and the degraded  quality thereof. In order to prevent the same, a refractory object D is pushed forcibly  into the metal 12 before the height of the level of the molten metal 12 lowers down to  hc to raise the height (h) of the metal 12, whereby the molten slag, nonmetallic inclusions, etc. are thoroughly separated, and the continuously cast ingot of high quality is  cast in high yields of the molten metal. This method is usable effectively for not only  continuous casting of single ingot but also sequential continuous casting of ingots and  continuous casting of dissimilar metals.

Abstract: PROBLEM TO BE SOLVED: To evaluate the flatness of a predetermined reflecting surface by averaging a plurality of second-dimensional images by an intensity pattern of reflecting light beams obtained by irradiating the reflecting surface with laser beams. SOLUTION: When a measurement is started, the evaluating apparatus 12 orders to obtain a second-dimensional image with a CCD image pickup element 25 by driving an optical system, then takes the image and holds the image in a recording means. A central processing unit(CPU) 26 judges whether or not the number of second- dimensional images becomes a predetermined number N. When a plurality of images are obtained, the CPU 26 averages the images and generates an evaluation reference image. An operation process is executed between each of second-dimensional images and the evaluation reference image, thereby generating a difference image. In response to operator's operation, the difference image is displayed to a predetermined display means. Each pixel value of the obtained difference image is statistically processed, thereby turning a flatness of a reflecting face to a numeric value and calculating as an evaluation value.
