Title: Inhibition or elimination of mold bulking in active sludge process for waste water
Inventor: SATOU TAKESHI
IPC: C02F3/12
Filed: 1980-05-24
Abstract: PURPOSE: To inhibit or eliminate mold bulking without effecting active sludge in an aerobic active sludge process by adding iodine into waste water containing the active sludge.  
     CONSTITUTION: Waste water is charged from a tank 5 into an aerating vessel 1, and agitated along with direction shown by an arrow by the injection of air from a sparger pipe 8. Sludge in the vessel 1 flows through a lower space below a partition plate 3 into a sedimentation vessel 2 owing to a level difference caused by the charge of the waste water. An upper portion in the vessel 1 constitutes a supernatant. Part of precipitated sludge is reused for contact with the waste water. In this process, iodine is added in the borm of a simple substance or its solution into the waste water containing the active sludge in the vessel 1. The solution is an aqueous halide solution containing dissolved I 2  esp. an aqueous KI solution, or a solution  containing an organic solvent such as alcohol, ether or the like. The solution is preferably an I 2  solution of a solvent having a low volatility and an ability to borm a  compound of I 2  with the solvent, because of the necessity of retaining I 2  for a long  time in the waste water under a sublimating condition.

Title: Method of variable damping drive of stepping motor
Inventor: KINTOU RIYOUICHI
IPC: H02P8/00
Filed: 1990-03-22
Abstract: PURPOSE:To reduce the noise in a low-speed region and allow the torque in a high-speed region to decrease little by changing a damping quantity with the rotational speed of stepping motors. CONSTITUTION:When a driving pulse is entered from a driving pulse generation circuit 5 to a drive circuit 2, the drive circuit 2 turns transistors Tr0-Tr3 on one by one and passes a current through the coils L0-L3 of stepping motors 10-13. When the transistors Tr0-Tr3 are turned off one by one, the coils L0-L3 generate counter electromotive force and the current is passed through a transistor Tr4 via diodes D0-D3 and returned to the coils L0-L3. The current passed through the transistor Tr4 brakes the stepping motors 10-13 to damp them. The damping quantity of the stepping motors 10-13 is changed by controlling the current passed through the transistor Tr4 with the output signal of a rotational speed inspection circuit 3.

Abstract: PURPOSE:To enable a detector to be positioned at the focus of a Cassegrain system and achieve easier adjustment by rotating the parabolic mirror and wedge form optical plate integrally in the infrared ray tracking appratus at a fixed ratio to the rotating period of its plane mirror. CONSTITUTION:The optical axis of a parabolic mirror 2' aligns to a rotating axis 6. A wedge form optical plate 8 whose both surfaces are polished mutually to an angle is installed to the parabolic mirror 2' and rotates together with said mirror. The angle alpha of the wedge form optical plate 8 may be expressed by formula [I] where the respective spacings between a plane mirror 3, wedge form optical plate 8 and detector 4 are let to be d1, d2. n is the refractive index of the wedge form optical plate 8. With such constitution, the portion of the parabolic mirror 2' which non- symmetrical to the rotating axis 6 is only the wedge form optical plate 8 and since this is small in the rate of mass occupying in the rotating portion and is close to the rotating axis 6, it hardly disturbs the rotating balance and its adjustment can be slight. In addition, the manufacturing errors of alpha may be compensated irrespective to balance by moving the mounting position forward or backward and may thus be readily adjusted.
