Abstract: PURPOSE:To obtain a CMOS gate circuit driven at a high speed, with less power consumption and offering high circuit integration by combining two CMOS transfer gates, a P-channel FET and an N-channel FET controlled by the same control signal. CONSTITUTION:With a control signal C1 at VCC level (H level) and a signal C1' at a VSS level (L level), P-channel FETQ5 and an N-channel FET Q6 are turned off, and two sets of CMOS transfer gates are turned on. Thus, an input signal A1 is inputted to gates of a P-channel FETQ7 and an N-channel FETQ8 as it is in this case, and the inverse of input signal A1 becomes an output signal B1. With the control signal C1 at L level and the signal C1' at H level, the two sets of CMOS transfer gates are turned off, the P-channel FETQ5 and the N-channel FETQ6 are turned on, both the P-channel FETQ7 and the N- channel FETQ8 are turned off and an output point 103 reaches a high impedance state.

Filed: 1989-03-20
Abstract: PURPOSE:To clean a heat roller soiled by carbonized paper powder etc., and to prevent leakage of silicone oil by projecting a blade element from the longitudinal side of a substrate and bringing it into contact with the surface of the heat roller. CONSTITUTION:The wiper assembly body 14 is applied to the heat roller 10 under condition where the blade element 20 faces downwardly and integrally projects from the longitudinal side of the substrate 16.

The signal is sent to a detection controller when the steel strip 3 shields the light 9 from the light projector 7 by meandering, etc., and the end thereof is detected. The edge mask 8 is then released from the steel strip 3 by the driving device 5, by which the contact with the steel strip 3 is prevented. The failure of the edge masks 6, 6a and the flawing of the steel strip 3 are thus prevented.

Title: Freeze-melt type sludge treatment unit
Inventor: HORIUCHI KOUICHI
IPC: C02F11/20
Filed: 1979-05-29
Abstract: PURPOSE: To provide sludge with the dehydration effect, without the use of toxic chemical such as ferric chloride, etc., to the same degree as its use by a method wherein sludge being treated discharged from a water treatment unit is deionized and then freezed and melted.  
     CONSTITUTION: Sludge discharged from a water treatment unit 21 is directly supplied to a sludge deionization unit 22 to lower the ion concentration of sludge being treated. The deionized sludge is then guided in a freeze-melt unit 3. This results in lowered specific electric conductivity (ion concentration) of the sludge which leads to an enhanced efficiency of the freeze-melt unit 3. Applicable sludge deionization units contain an ion exchange resin filled tower, an electric dialyzer, or backosmosis unit.
