Title: Method for removing silicon from hydrochloric acid-pickled waste liquid
Inventor: KONDO HIDENOBU
IPC: C01G49/06
Filed: 1986-12-03
Abstract: PURPOSE:To readily remove SiO2, efficiently purify hydrochloric acid and effectively perform production of high purity iron oxide, by adding carbonaceous substance having hydrophilic group into hydrochloric acid-pickled waste liquid, stirring and removing solid content. CONSTITUTION:A carbonaceous substance having hydrophilic group such as hydroxyl group, carboxyl group, etc., is added to a hydrochloric acid-pickled waste liquid, stirred and solid content is removed. The above-mentioned method is based on function of the carbonaceous substance promoting polymerization of fine SiO2.nH2O in the waste solution, since the carbonaceous substance having hydrophilic group on the surface has affinity with the SiO2.nH2O. Fine powders or granules of carbon black, acetylene black, etc., are preferable as the carbonaceous substance. The finer particle size is, the better it is in order to enlarge content area with SiO2.nH2O in the acid-pickled waste liquid, but the particle size of about 0.1-1.0mu is better, in consideration of removing property of solid content after stirring.

Title: Movable magnet type linear actuator
Inventor: OKADA YUKIHIRO
IPC: H02K33/16
Filed: 1999-10-08
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a magnetic force cannot be obtained efficiently because a force is generated in the opposite direction to a thrust due to relative positional relation between the pole end part of an outer yoke in the axial direction and the axial end part of a permanent magnet when a movable part moves. SOLUTION: The linear actuator comprises an inner yoke 1, an outer yoke 2, a drive coil 3 wound around the outer yoke 2, a permanent magnet holding member 5, and a permanent magnet 4 magnetized substantially in the radial direction. Since the axial length at the pole part of the outer yoke is equal to or longer than the stroke and the axial length of each of a plurality of permanent magnets is substantially equal to the axial distance between centers of the pole parts abutting on the outer yoke, a force generated reversely to thrust due to relative positional relation between the pole end part of the outer yoke in the axial direction and the axial end part of the permanent magnet is suppressed to generate a magnetic force efficiently thus increasing the thrust.

IPC: H03C1/54
Filed: 1988-11-16
Abstract: PURPOSE: To minimize amplitude fluctuation by obtaining a sine wave output signal subject to phase modulation corresponding to a control signal and whose amplitude is almost constant. CONSTITUTION: The phase modulation circuit is made up of a couple of similar long tailed pair transistor(TR) amplifiers TR11-TR14 receiving a sine wave signal. The TR pairs are collector loads of other long tailed pair TRs 21, 22 receiving modulator signal and the circuit generates an output whose amplitude is constant and the phase corresponds to a modulated signal.
