Title: Backwashing device of cylindrical element type filter
Inventor: SHIMADA KENJI
IPC: B01D29/62
Filed: 1983-02-10
Abstract: PURPOSE:To enable a titled device to backwash effectively with a small amount of water, by piercing holes in the wall of a water introducing pipe of each filtering element to form a liquid, flowing in the pipe, into a water-air mixed flow. CONSTITUTION:In backwashing a cylindrical element type filter, a valve V1 of washing water is opened to fill the inside of a housing 5 at the filtrate side with water 7. Next, after closing the valve V1, when a back-washing gas valve V2 is opened to supply a pressurized air, the water 7 flows from the inside of each filter element 1 to its outside through each water introducing pipe 6 to backwash the elements 1 by the action of the gas. At that time, as small holes 8 pierced in each pipe 6 wall catch up air into the water by the action of a water flow pump, washing is performed by the produced water-air mixed flow. Accordingly, the washing is effectively performed by the produced high-speed water flow without causing an uneven washing, and the cake deposited on the surfaces of the elements 1 and the particles captured between the metallic wires of elements 1 are removed.

Title: Method for monitoring and controlling water treatment system
Inventor: KUBOTA MASAYOSHI
IPC: C02F3/06
Filed: 1994-02-21
Abstract: PURPOSE:To execute an optimum back washing process and to assure smooth operation control of a high-grade water purifying treatment system by measuring adhesion and propagation of microorganisms in packed beds and growth from an upper bed part to a lower bed part during treatment and controlling the frequencies and/or intensity of back washing in accordance with the measured values. CONSTITUTION:The packed bed height of active carbon 28 of a biologically active carbon column 20a is generally about 2m and an observation device 30 consisting of an endoscope is installed up to about 1/2 this height.

Title: Automatic opening/closing equipment for car window
Inventor: TSUKASAKI HITAKA
IPC: E05F15/20
Filed: 1984-02-08
Abstract: PURPOSE:To enhance reliability by detecting a window-closing-prohibiting state and forming a system so that, corresponding to this detection signal outputting of window driving signal for window closing is prohibited. CONSTITUTION:When an air-conditioning operation switch 50 is operated while a window is open or when a seat switch 70 signal flickers due to a driver's leaving his seat while the air-conditioning equipment is operating, an AND gate 90a produces a high-level signal, while an inverter 100a outputs a low-level signal in cooperation with an OR gate 90c in order to prevent a high-level signal from an AND gate 100b from being produced. Accordingly, even if an up-switch 10 is closed by mistake in this state, the AND gate 100b is unable to output a high- level signal because of the low-level signal issued from the inverter 100a, and a driving relay 40 keeps a double-throw contact 42c of a double-throw switch 42 in contact with a fixed contact 42b, thereby preventing the window from being closed. With this contrivance, both reliability and durability can be enhanced.

Title: Optical recording medium
Inventor: SUGIMOTO MAMORU
IPC: G11B7/2433
Filed: 1987-02-03
Abstract: PURPOSE:To obtain a new optical recording medium which has raised the recording surface density of the optical recording medium by about one figure, by constituting it of an ultrafine grain consisting of a magnetic material or a dielectric, and a high polymer material for holding the ultrafine grain. CONSTITUTION:An ultrafine grain 1 having a shape anisotropy is mixed into a linear polymer 2. A laser irradiating part 3 is heated above a glass transition temperature at which a thermal expansion coefficient increases suddenly. In this state, a Co ultrafine grain 1' is oriented in the vector direction of a magnetic field H by impressing a magnetic field H4 from the outside. When the laser radiation is cut off, the irradiated part grows cold quickly and the fine grain is oriented and recorded. A read-out method is reproduced by limiting the laser power at the time of read-out so that a temperature rise of a read-out part becomes below the temperature Tg. By this theory, polyimide is used as a target for spattering, barium ferrite is used as other target, and sputtering is executed simultaneously. This composite film is heated to above the temperature Tg of a polyimide thin film by a laser, and oriented by impressing an electric field E. At the time of read-out, the laser power is limited so as to become below the temperature Tg, and a polarization angle of light is read.

Title: Memory device
Inventor: KUBO KENKICHI
IPC: G11C11/409
Filed: 1989-02-01
Abstract: PURPOSE:To reduce crosstalk noise produced by a high working speed without deteriorating the high speed property by setting the half of output signal lines at logic '0' and the other half of output signal lines at logic '1' respectively when the output is kept in a high impedance state. CONSTITUTION:The half of output signal lines (a)-(h) of a memory element 1 are connected to a low potential 2 via a pull-down resistance 4 with the other half of the lines (a)-(h) connected to a high potential 3 via a pull-up resistance 5 respectively. Thus the influence of the output switch can be reduced. In other words, a buffer 6 opens before the output of the element 1 is fixed when a memory reading action is started. Thus the transient data obtained by the pull-down and pull-up operations are outputted from the buffer 6. As a result, the number of signal lines changing in the same direction at the same time can be decreased. Thus it is possible to reduce the crosstalk noise produced by the high working speed without deteriorating the high speed property.
