Title: Method for treating flue gas desulfurization drainage
Inventor: OCHI EIJI
IPC: C02F1/70
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To remove inhibition factors by oxidizing substances contained in drainage and to perform biotreatment stably and efficiently by a process in which a reducing agent is added before a biotreatment process is order to decompose peroxosulfuric acid, which is an oxidizing substance contained in drainage, and biotreatment is implemented. SOLUTION: Desulfurization drainage 21 is introduced into a flocculation/ precipitation tank 1. After flocks generated in the tank 1 being precipitated, the supernatant is introduced into an oxidizing substances decomposition tank 2a. In order to decompose peroxosulfuric acid, treated liquid introduced from the tank 1 is mixed with an iron (II) compound 25 under neutral conditions. Water-soluble iron (II) salts such as iron (II) sulfate and iron (II) chloride are used as the iron (II) compound 25. The treated liquid from here is introduced from a nitrification tank 3 into a denitrification tank 4 to be subjected to nitrification/denitrification treatment. By decomposing oxidizing substances such as peroxosulfuric acid contained in the desulfurization drainage 21, a succeeding nitrification/denitrification treatment can be done smoothly without affecting microorganisms.

Title: Barrel plating method
Inventor: TSURUSHIMA KUNIAKI
IPC: H01L23/12
Filed: 1982-10-20
Abstract: PURPOSE:To smooth the replenishing of the metallic ion in a barrel and to reduce a plating time by oscillating a plating cell in a barrel plating method by an ultrasonic wave. CONSTITUTION:An ultrasonic vibrator 33 is mounted on the base of an ultrasonic oscillation tank 31, and water is put into the tank 31, in which a plating cell 21 is provided. A barrel 11 is rotated in the cell 21, and the metallic ion in the cell 12 is admitted into the barrel 11 through the many small holes provided thereto, whereby the object to be plated provided with a negative potential in the barrel 11 is plated thereon. Since the stirring effect of the ultrasonic wave by the vibrator 33 is utilized, the metallic ion is easier to flow into the barrel 11 and the decrease in the metallic ion in the barrel 11 is prevented, whereby the plating time is reduced.

Title: Manufacture of si3n4 powder
Inventor: TSUKADA HIROSHI
IPC: C04B35/626
Filed: 1980-12-24
Abstract: PURPOSE: To manufacture Si 3 N 4  powder with superior sinterability as starting material for manufacturing a sintered Si 3 N 4  body by removing components of balls for pulverization entering powder during pulverization by a magnetic separation method.  
     CONSTITUTION: Si 3 N 4  synthesized by a solid phase reaction method or a vapor phase reaction method is pulverized with an attriter using balls for pulverization made of superhard WC-Co alloy so that the average grain size is regulated to ≤1μm, and ≥90% of the resulting powder has ≤3μm grain size. WC and Co enter the powder as impurities during the pulverization owing to the wear of the used balls. Since WC enhances the sinterability to some degree, ≤20% WC is allowed to be contained, yet Co deteriorates the characteristics of a sintered Si 3 N 4  body at high temp. even if a trace of Co is contained, so Co is separated and removed to ≤1% Co by a magnetic separation method. The powder is then sintered by hot pressing at 1,700°C to obtain a sintered Si 3 N 4  body with superior creep resistance.
