Title: Platinum plating method on ion exchange membrane
Inventor: SUGA CHOICHI
IPC: C25B9/23
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To plate both surfaces of a membrane with platinum at one time by grinding the surfaces of a membrane to obtain rough surfaces, forming a platinum thin film on each surface by sputtering, heat treating in hot water, treating with a reducing agent in a hydrazine-hydrate soln., and bringing the both surface into contact with a chloroplatinic acid soln. in a fluidized state. SOLUTION: After the surface is polished, the membrane is boiled in boiling pure water for 1 to 2 hours to remove impurities. Argon gas is introduced into a sputtering device, the pressure is adjusted to almost 10<-1> Pa to generate glow discharge between a platinum target and a substrate on which an ion exchange membrane is mounted. Thus, sputtering is caused to deposit platinum atoms on the ion exchange membrane to form a thin film. Then the membrane is heat-treated in warm pure water and reduced in a hydrazine monohydrate (H2 NNH2 .H2 O) soln. Then the ion exchange membrane 1 is held and fastened in plating cells A and B, a chloroplatinic acid (H2 PtCl6 .6H2 O) soln. 5 is supplied through a ventilation port and circulated by a circulating pump D so that the liquid in a fluidized state is brought into contact with the membrane to plate the both surfaces at one time.

IPC: C02F3/00
Filed: 1992-06-12
Abstract: PURPOSE:To obtain a septic tank wherein a sludge is hardly discharged even if a large amt. of original water flows in and the quality of treated water is good by providing a precipitation tank at the downstream of a contact aeration tank so as to communicate them below a partition wall and providing not only an aeration pipe generating a circulation flow in the contact aeration tank but also a returning part projecting at the lower end part of the partition wall.

In addition, aeration pipes D1 for generating a circulation flow in the contact aeration tank E are separately positioned in such a way that they are spaced apart left and right in the flow direction. In addition, a returning part is provided projecting to the contact aeration tank side larger than the left and right positions at the lower end part of the partition and at the central position in the width direction. Namely, as both a flow passing below the partition wall W1 and entering from the aeration tank E into the precipitation tank P and a flow returning from the precipitation tank P to the aeration tank E can obtain a flow with a relatively strong power, sludge hardly stays in the precipitation tank P and as the result, even if a large amt. of original water flows in, the sludge is hardly discharged.

A cavity 20 is formed on one end of an elastic body 18 fixed with adhesive between the inner cylinder 12 and the intermediate cylinder 16, and a notch 22 is formed on the opposite side of the cavity, a liquid being filled in the notch 22. In the notch 22, a vibration -absorbing unit 30 is arranged and small liquid chambers 39A and 39B connected by an orifice 44 are formed. When the vibration of an engine is produced, the pressure in the small liquid chamber 39A rises due to elastic deformation of the elastic body 18, and is transmitted to the small liquid chamber 39B through the orifice 44, then compresses an air chamber 40. The vibration of the engine can, therefore be absorbed.

Abstract: PURPOSE:To decrease the number of parts and assembly man-hours by fitting lenses directly to a carriage main body and to easily adjust the eccentricity of the lens only by finely adjusting the fitting state such as the inclination of the carriage main body. CONSTITUTION:The lenses 4, 5, and 6 are inserted into the lens insertion hole 3 of the carriage main body 1 and fixed with a pressure ring, and then the carriage main body 1 is fixed to a slide part 2 held on a guide rail.

Title: Analog switch circuit
Inventor: TSUCHIYA CHIKARA
IPC: H03K17/62
Filed: 1981-09-29
Abstract: PURPOSE:To reduce stray capacity appied to the base of an output transistor (TR) and to improve the output frequency characteristics, by connecting a diode between the base of the output TR and a control circuit. CONSTITUTION:When a control circuit CT is conductive, since an analog signal from a signal source SG and a DC signal from a DC bias power supply VA is applied to the control circuit CT via a resistor R and a diode D, a TRO1 is interrupted and no analog signal appears at an output terminal OUT. When the control circuit CT is interrupted, since VA>VB is obtained, the Q1 is turned on, and when a voltage drop due to the resistor R at the Q1 conduction is neglected, and a signal superimposing an analog signal on a constant DC voltage is obtained at the output terminal OUT. Thus, when the control circuit CT is interrupted, since the effect of a stray capacitance Cs2 of an element constituting the control circuit CT is eliminated, the frequency characteristics of the output  signal are improved.
