Abstract: PURPOSE:To produce an electrode which is small in chlorine overvoltage and excellent in durability by using rutile-type composite oxide having a prescribed composition as a coating having electrode catalytic activity for an anode for especially electrolyzing brine by an ion exchange membrane method. CONSTITUTION:Electrically-conductive metal having corrosion resistance such as Ti is used as an electrically-conductive base material and the base material is properly subjected to surface cleaning treatment and the coating having electrode catalytic activity is formed thereon. The coating is composite oxide basically consisting of 35-60mol% Ir oxide and Ru oxide, 65-20mol% In oxide and Sn oxide and 1-20mol% Ti oxide. A rutile-type crystalline structure is substantially used as a main material in the composite oxide. Among these, durability is enhanced by Ir oxide and chlorine overvoltage is made small by Ru oxide. Further both Sn oxide and In oxide have the action lowly maintaining chlorine overvoltage. Also Ti oxide has the action increasing the physical and chemical stabilization. Therefore chlorine overvoltage is made small and durability of the electrode is excellent.

Title: Flow regulation valve
Inventor: OTANI KOICHI
IPC: F16K47/02
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To restrain pressure loss to the minimum level while preventing generation of sound from a metering orifice by dividing a flow path to one flow out inlet from the metering orifice by means of noise board. SOLUTION: In the case of reducing pressure loss by maintaining the opening of metering orifice large to some extent, a noise reduction plate (p) is overrupped on only a small dia. orifice 8b to secure the flow 20 of a large dia. orifice 8a and divide the flow path on the side of space 18 into two directions. Pressure loss caused by the board (p) is thereby reduced. In this case, the pressure oil flowing out of the orifice is guided with a cylindrical member 17 to flow also in its cicumferential direction. The pressure difference between the front and rear of the orifice does not large so much when the orifice 8a is open, and thus generation of noise causes no trouble.

Title: Brush electrostatic charging and transferring device
Inventor: OKUNO TATSUO
IPC: G03G15/16
Filed: 1984-04-12
Abstract: PURPOSE:To improve transfer efficiency by bringing a conductive brush into contact with a photosensitive body, and impressing an AC superposed DC voltage which is generated by superposing an AC voltage upon a DC voltage by >=20% and is + or -200-+ or -2,000V to the conductive brush. CONSTITUTION:A contactor 12 contacts the reverse surface of a transfer material 8 gently during transfer as shown in the figure to charge electrostatically the reverse surface of the transfer material 8 uniformly, so a visible image (toner) on a photosensitive body 2 is transferred to the surface of the transfer material 8 by electrostatic attraction. Then when a DC voltage lower than 200V is impressed to the conductive brush 13, the electrostatic attraction of the toner is weakened because the transfer material has a low potential, so the toner is not transferred sufficiently. When the impressed voltage is >=2,000V, on the other hand, discharge is caused between the transfer material and toner particles or among toner particles to decrease the electrostatic charge quantity of toner or invert the polarity, thereby lowering the transfer efficiency. For the purpose, the impressed voltage is set to + or -200-+ or -2,000V, and then electrostatic charge uniformity is improved and the transfer efficiency is made superior.
