Title: Removal of selenium in waste water
Inventor: HARADA TAKESHI
IPC: C02F1/58
Filed: 1995-06-20
Abstract: PURPOSE: To remove selenium from waste water easily and effectively to reduce the amt. of a precipitate by adding hydrazine or a hydrazinium salt and a mineral acid to a selenium-containing waste water and heating this waste water to specific temp. under an acidic condition to form a selenium-containing precipitate to subject the same to solid-liquid separation. CONSTITUTION: Hydrazine or a hydrazonium salt and a mineral acid are added to a selenium-containing waste water and this waste water is heated to 50 deg.C or higher under an acidic condition to sediment a selenium-containing precipitate. Hydrazine or hydrazonium ions in waste water is decomposed to water and nitrogen gas by heating. After reaction, the selenium-containing precipitate is separated from waste water by filtering to be removed from waste water. Selenium is recovered from the precipitate if necessary. The selenium removing effect is extremely high and the residual concn. of selenium in a filtrate can be reduced to a large extent. By repeating this treatment process, since the concn. of selenium can be reduced to the waste water standards or less, environment is not polluted even if the treated waste water is discharged.

Title: Dot printer head
Inventor: NORIKOSHI TAKASHI
IPC: B41J2/24
Filed: 1983-09-26
Abstract: PURPOSE:To reduce the equivalent mass of an armature and carry out printing at high speed with low electric consumption by increasing the attracting power of a core through the return of a magnetic flux through an adjacent armature. CONSTITUTION:An armature 18 equipped with a needle for dot printing 11 is guided with an armature guide 20 fitted into a guide hole provided near a fulcrum 21 of the armature. Consequently, the distance l1 between the fulcrum 21 and a core 17 becomes short, narrowing a gap C. At the same time, it is possible to narrow a distance l4 between an armature and its adjacent armature. Under this structure design, a magnetic flux returns from the core 17 to the core 17 through the armature 18 and simultaneously, the flux returns to the core 17 via the adjacent armature 18, magnifying the attracting power of the core 17. As a result, it is not necessary to widen the area of the armature 18 opposed to the yoke 17 and instead, to minimize the equivalent mass of armature. Thus printing can be carried out at high speed with low electric consumption.
