Title: Activated sludge treatment using cristobalite
Inventor: NONOU TOSHINOBU
IPC: C02F3/08
Filed: 1984-02-21
Abstract: PURPOSE:To rapidly discharge suspended substances containing molds out of the system, by adding and suspending cristobalite or a material based on cristobalite in an aeration tank for treatment of waste water according to an activated sludge method. CONSTITUTION:Naturally produced porous cristobalite, which contains 80-90% of a silicic acid component, is a spherical aggregate with a diameter of 5-10mum and has fine pores with a diameter of 20-200Angstrom , a specific surface area of 60- 70m<2>/g being about 3 times or more that of natural zeolite and an apparent void ratio of 40-50%, is crushed to reduce the particle size thereof to 1mm. or less. This cristobalite is added and suspended in an aeration tank for treatment of waste water according to an activated sludge method to perform activated sludge treatment. By this treatment, because microorganisms are adhered to and propagated on the surface of cristobalite and the precipitation of sludge is promoted, suspended substances containing molds can be rapidly discharged out of the system and a bulking phenomenon can be eliminated.

Filed: 1993-02-19
Abstract: PURPOSE:To invalidate whole ATB entries, to considerably shorten the time of an ATB clearing processing and to improve ATB access performance by updating an ATB clearing instruction count value by means of an ATB whole entry clearing instruction. CONSTITUTION:When an ATB index request is given to an address in a state where it is registered in ATB, a value registered in a count value registration register 2 is the same as the value of a count field 4a in an ATB key part 4 if the ATB clearing instruction is not given until indexing is executed after the address is registered in ATB. Thus, it is judged to be an ATB unit. When an ATB clearing instruction is given until indexing is executed after a prescribed address is registered in ATB, the value registered in the count value registration register 2 differs from the value of the count field 4a in the ATB key part 4. Thus, it is judged to be an ATB mishit.

Title: Logic integrated circuit device
Inventor: KANI KENJI
IPC: H03K17/76
Filed: 1978-03-16
Abstract: PURPOSE:To increase the utilization efficiency and the operation speed, by sectioning the input lines of logic array via diodes and switching them depending on the write-in distribution to the logical elements provided on the matrix cross points with the output lines. CONSTITUTION:The diodes 21 to 24 are placed on the input wiring of the logical product array, and the terminal v side can usually separated when viewed from the input x side. The wirings 25 to 28 of the logical product output z are crossed with the input lines via the load resistor R to the power supply Vcc and the diode pair is present at the cross points. At write-in, when the lower line from the diode is used, for example, the prart 15B of the input wiring x1 is used, the diode 21 is shortened, and other input wirings, for example, write-in is made only to the elment pairs 11, 12 connected to 16A, and no write-in is made to the element pair at 16B. thus, since the logical elements for unnecessary parts and the input lines are eliminated, the stray capacitance is reduced. If the lines having much utility are assigned to the parts 15 to 18A, the diodes can effectively be used and lowering in the operation speed can be avoided, and input is possible from the terminal v and the degree of integration is greater.

Title: Reel driving circuit
Inventor: NAWATA YASUSHI
IPC: G11B15/46
Filed: 1981-03-02
Abstract: PURPOSE:To reduce the fluctuation of winding speed and to achieve stabilization against external disturbance, by providing a reel driving circuit which decreases the ratio of fluctuation of number of revolutions of a winding motor to the fluctuation of number of revolutions of a motor to be wound at a high speed. CONSTITUTION:A base emitter voltage of a transistor 12 (TR) and a forward voltage of a diode are denoted as 0.6 volt in this case. If the collector and the emitter of the TR12 are shortened and a counter electromotive force of a motor 2 is increased, the collector voltage of the TR12 is lowered and a voltage between the collector and the emitter is saturated. The ratio of the fluctuation of  revolutions of a winding motor to the fluctuation of revolutions of a motor 2 to  be driven is (580-500)/(500-380)=0.67. Thus, the ratio of fluctuations can be reduced to about 1/10, allowing to achieve stabilization against external disturbance.
