IPC: B01D25/12
Filed: 1989-03-24
Abstract: PURPOSE:To effectively remove filter cake from the filter cloth on the side of a pressed filter plate by feeding filter cake separating liq. to the side of a pressing filter plate through between filter cloth on the side of a pressed filter plate and the pressed filter plate adjoining thereto after undergoing pressing process. CONSTITUTION:In a filtering process, unfiltered liq. is supplied by a pump 5 from an unfiltered liq. tank 6 through unfiltered liq. supply holes IC and 2C into a filter chamber located between a pair of filter cloths 3 and the resulting filtrate is recovered in a filtrate tank 7. After undergoing the subsequent process of filter cake through washing, pressing and center blow, in the next back washing process, cleaning water is sent by a pump 9 from a cleaning water tank 8 through fourth through openings 1h and 2h and then through a filter cloth 3 adjoining to a pressed filter plate 1 into the filter chamber in a reverse direction from filtration or filter cake through washing process, whereby the water is run between the filter cloth 3 and the filter cake to make easy the separation of the filter cake from the filter cloth 3. The cleaning water entering the filter cake passes through the filter cloth 3 on the side of a pressing filter plate 2 and then through the unfiltered liq. supply holes 1C and 2C into the unfiltered liq. tank 6 for recovery. After being subjected to the process of removing residual pressure, water and filter cake, a circulation of such processes is brought to an end.

Abstract: PURPOSE:To eliminate the dispersion of the interval of data receiving time at terminal equipment, and to use the receive data processing capacity of a central processing part to its limits by regulating transmitting timing from a terminal dealing part to the terminal equipment by a clock pulse. CONSTITUTION:An interruption control part 17 detects the leading edge of the clock pulse B, and issues an interruption signal, and a microprocessor 11 executes receive data processing and transmit data processing by this interruption signal, and transfers transmit data to a communication control part 2. After that, it sets interruption to the microprocessor 21 of the communication control part 2. When the interruption is set, the communication control part 2 executes the transmit data processing, and transfers the transmit data to each terminal dealing part 3,3,.... The receive data processing and next, the transmit data processing are executed synchronously with the leading edge of the clock pulse, and the transmit data is sent to the terminal dealing part through the communication control part, and is transmitted to the terminal equipment synchronously with the trailing edge of the clock pulse. Since similar procesing is executed in a following cycle, the time interval of receiving timing at the terminal equipment coincides with the period of the clock pulse.

Abstract: PURPOSE:To manufacture an oriented material of good thickness accuracy and with little uneven shrinkage at the time of heat shrinking by specifying the orientation speed in one direction and the orientation speed in the other direction when a biaxially oriented material is manufactured, and specifying the time for placing the material at the glass transition temperature or higher and orienting. CONSTITUTION:A film or sheet-shaped pulling biaxially oriented material of copolymer resin composed of 99-85wt.% of methacrylic methyl unit and 1-15wt.% of acrylic acid alkyl ester unit having 1-4 alkyl carbon and having 0.5-12g/10min. of melt flow index is manufactured. At that time, the material is oriented under the orienting conditions that the orientation speed in one direction is 1000-50000%/min. and the orientation speed in the other direction 200-50000%/min. and that the time of placing the oriented material at the glass transition temperature or higher during the process from the start of orientation to the completion of the same and the time for releasing the oriented material is 5 minutes or less. As the orientation speed enhances the uniformity of orientation degree, the speed in one direction is set as 1000%/min. or more, and 200%/min. or more is set in the other direction. When it is too speedy, stress required for orientation gets large to generate breakage during the orientation, and the speed should be controlled to 50000%/min. or less.

Abstract: PURPOSE:To improve sensitivity and resolution and to implement high density, by alternately arranging a plurality of light receiving elements and vertical transfer CCDs, which are aligned along the direction of a column, injecting signal charge in a substrate by pairs of MOS electrodes, which are scanned by a horizontal transfer control part, and reading the charge. CONSTITUTION:Signal charge, which is stored in a light receiving part 1, is simultaneously transferred to a vertical transfer CCD as the total picture elements during a part of a vertical blanking period. The signal charge, which is moved to the vertical transfer CCD, is sent to pairs of MOS electrodes 3 at the standard scanning speed of television. At this time, a signal for one scanning in the vertical direction is sequentially transferred downward in parallel with other signals. At the same time when a gate electrode 9 is cut OFF, only an electrode 31, in which the signal charge is stored, is set at an L level. The signal charge is moved to a part beneath another electrode 32. When the electrodes 32 are sequentially scanned by a horizontal shift register 5, the charge is injected in a substrate 6. The charge is taken out as a video signal in one horizontal direction through a circuit 8.

Abstract: PURPOSE: To increase the driver-awakening effect of a detector for the dozing of a driver at the wheel, by providing the detector with an alarm circuit adapted to receive as an input thereinto an output from a circuit for use in detecting the degree of waking of a driver, and to give an alarm in accordance with the degree of waking of a driver.  
     CONSTITUTION: When a decrease in the degree of waking of a driver has been ascertained in a circuit 10 for detecting the dozing of a driver at the wheel to output an alarm signal therefrom, a one-shot multivibrator 11a is turned on for a predetermined period of time by the first pulse of the alarm signal. Consequently, a light emitting diode 15 is connected to a power source 13 through an electronic switch 12a. When the second pulse is output from the circuit 10, a one-shot multivibrator 11b is turned on to allow a speaker 18 to give an alarm. When the third pulse is output, a one-shot multivibrator 11c is turned on, and an electronic relay 12c is A-C connected to turn on a driving transistor 20. As a result, a fan motor 22 is intermittently driven. When such three kinds of alarm means are operated in order in accordance with the cumulative degree of alarm signals, the driver-awakening effect of detector for the dozing of a driver at the wheel can be increased to a great extent.

Title: Manufacture of semiconductor substrate
Inventor: HAYASHI HISAO
IPC: H01L27/12
Filed: 1989-03-27
Abstract: PURPOSE:To easily manufacture a very thin film substrate by a method wherein, after a P-type semiconductor substrate is stuck on the other retaining substrate via an insulating layer, the substrate is made porous, oxidized and eliminated. CONSTITUTION:On a main surface of a P-type silicon substrate 11, an N-type thin layer 12 is formed; substrates 14, 16 are heat-treated in the manner in which each of the SiO2 film comes into contact with each other, thereby sticking the substrates. The substrate 11 of the substrate 14 is thinned by grinding, and made porous by anodizing. Since the stuck substrate is divided into the upper substrate 11 and a lower substrate 15 by the SiO2 layer 13, the electrode is formed by using the substrate 11 side. The substrate 11 which has been made porous is thermally oxidized in an oxygen atmosphere, and turned into an SiO2 layer 17, which is etched and eliminated in HF solution. Thereby the N-type thin layer 12 only is left, and a very thin SOI substrate 18 can be obtained. Since a sticking system is used, a silicon thin film free from defects can be realized.
