Title: Method for switching polarity of electrode of electrolytic bath in electrolyzed water treatment apparatus
Inventor: OKAZAKI TATSUO
IPC: C02F1/46
Filed: 1994-09-03
Abstract: PURPOSE: To prevent an platinum component from being dissolved from the surface of electrodes, especially from the electrodes the surface of which are treated with a metal of a platinum group when the polarity of the electrodes is changed over by extracting water existing between the electrodes in an electrolytic bath and then introducing water between the electrodes when the polarity of the electrodes in a water electrolysis bath is changed over. CONSTITUTION: In the electrolytic bath of a water treatment apparatus by electrolysis, electrodes in which the polarity of electrodes, etc., in which the surface of a titanium material is treated with a metal of platinum group can be changed over are used, and electrolyzed water treatment is carried out while the polarity of electrolytic electrodes being changed over every specified time. When the polarity of the electrodes is changed over in such an electrolytic bath, water existing between the electrodes in the electrolytic bath is extracted to change over the polarity of the electrodes to be controlled so that water is introduced between the electrodes after the polarity being changed over.  By discharging temporarily water existing between the electrodes when the polarity of applied voltage is changed over, a solvent which is dissolved is eliminated between the electrodes to control the elution of a metal of platinum group from the surface of electrodes, especially from the electrodes the surface of which is treated with a metal of a platinum group.

Title: Constant current control circuit
Inventor: ISHIYAMA HISANOBU
IPC: H03M1/64
Filed: 1990-09-05
Abstract: PURPOSE:To reduce current consumption by stopping a current from a constant current source when an electric circuit is not used by using a reference transistor, switch circuit and inverter. CONSTITUTION:This circuit is equipped with a reference transistor 1, operation transistor 200, switching circuits 3 and 4 (composed of transmission gates and having terminals A and B turned to a conductive state by impressing a potential at an L level to a terminal C), resistor 7, and inverter 6. In this case, by impressing a potential at an H level to a control terminal 11, the switching circuit 3 is turned on and the switching circuit 4 is turned off. Therefore, the potential at the H level (VDD potential) is applied to the gate of the reference transistor 1, and the transistor is turned off. Thus, since the constant current can be interrupted when it is not required, the current consumption can be suppressed.

Title: Method for suppressing corrosion of steam condensate piping for boiler
Inventor: USUI NAOSHI
IPC: C23F11/08
Filed: 1983-12-16
Abstract: PURPOSE:To suppress corrosion of a steam condensate piping for a boiler by feeding a volatile pH increasing agent and volatile disoxidation agent to the water feed line of the boiler or the boiler so that the pH of the condensate of the generated steam is made alkaline. CONSTITUTION:Morpholine or the like as a volatile pH increasing agent and hydrazine or the like as a volatile dixoxidation agent are feed to the water feed line of a boiler or the boiler. The hydrazine reduces and removes the oxygen in the feed water in the boiler and prevents the corrosion in the boiler; at the same time the hydrazine evaporates together with the generated steam and increases the pH of the condensate. The morpholine evaporates to increase further the pH of the condensate and makes the pH about >=9.0 thus suppressing the corrosion of the condensate piping. The morpholine is preferably fed to the boiler water at about 7-15ppm to maintain the pH of the condensate in about 9.0-9.4 range in order to suppress the corrosion of iron and copper alloy.

Title: Paint composition
Inventor: MASAOKA YOSHIJI
IPC: C08L101/00
Filed: 1983-12-16
Abstract: PURPOSE:To obtain paint having excellent long period weather resistance, by using a chlorinated polyolefin having a specified chlorine content as the main film-forming element. CONSTITUTION:A paint compsn. having internal plasticity contains a chlorinated polyolefin having a chlorine content of 50-60wt% as the main film-forming element. When the chlorine content exceeds 60wt%, the resulting coating film is hard and brittle and hence, a large quantity of a plasticizer must be used together with the polymer, while when the chlorine content is less than 50wt%, the resulting coating film becomes tacky and as a result, a problem is caused that dust adheres to the film. A small quantity of a plasticizer or a resin such as a petroleum resin, an alkyd resin, a phenolic resin, an acrylic resin, a vinyl chloride resin, an ethylene/vinyl acetate copolymer or a bitumen compatible with the chlorinated polyolefin can be blended with the paint compsn.
