Title: Method for restoring capacity of ultrafiltration module
Inventor: HASHINO YASUO
IPC: B01D65/02
Filed: 1981-09-11
Abstract: PURPOSE:To restore the capacity of an ultrafiltration module of which water permeation amount is lowered, by a method wherein the module is filled with alcohol and succeedingly washed by water. CONSTITUTION:An ultrafiltration membrane is preliminarily wetted with a liquid having compatibility with water and a membrane material and said liquid is thereafter replaced with water. As the above described liquid, alcohol is designated. In the case of a contaminated membrane having a filter cake accumulated on the surface thereof, said membrane is wetted with an inventive restoring agent as is contaminated and, after said restoring agent is replaced with water, washed by a chemical cleaning agent or a dispersant cleaning agent to restore the filtering capacity thereof. As the restoring agent, ethanol, methanol or  butanol are designated. In this case, after the membrane is washed by a conventional cleaning agent, it is wetted with alcohol and, after said alcohol is replaced with water, washed by the cleaning agent to effectively restore the filtering capacity thereof. This method is effective in restoring the lowering of the filtering capacity when the ultrafiltration membrane is exposed to air for a long  time by oversight or used in filtering raw water in which air bubbles are entrapped for a long time.

Title: Simulator of continuous casting equipment
Inventor: WATABE YOSHIAKI
IPC: B22D11/18
Filed: 1990-05-31
Abstract: PURPOSE:To allow stable control by regulating the mold level control of continuous casting equipment by using a simulator motor before an actual molten metal is passed. CONSTITUTION:The reference signal of stopper opening degree is applied by a stopper opening degree reference circuit 10. A mold level signal is negatively fed back by a mold level gage circuit 7. The deviation value of the signals of both circuits 7, 9 is corrected by a PID compensation circuit 1. The stopper opening degree is detected by a stopper opening degree detector 3. The stopper opening degree is amplified by a flow rate function device 4. This output is multiplied to the sectional area of the cold part by a mold sectional area multiplier circuit 5. The basic flow rate of the mold is added to output of this circuit 5 and is fed back round to the output system of the PID compensation circuit 1 by a basic flow rate function device 6. The simulator device of the continuous casting equipment is thus constituted. The mold level control is adjusted by using the simulator before the actual molten metal is passed with respect to the control of the mold level in such a manner. The hot line adjustment by the actual molten metal is smoothly risen in this way.

Filed: 1984-07-10
Abstract: PURPOSE:To enable an easy removal of a driving element of an air filter driving device by a method wherein a shape memory alloy is applied as the driving element. CONSTITUTION:An air filter driving device 8 for use in removing an air filter 3 out of an air feeding circuit is arranged.

Title: Optical disk device
Inventor: YASUJIMA TAKUMI
IPC: G11B7/085
Filed: 1990-05-31
Abstract: PURPOSE:To accurately record on an optical disk without being affected by a flaw of the disk or a vibration due to a disturbance by supplying a semiconductor laser with a comparatively high driving current to obtain a focus error signal more than a prescribed value. CONSTITUTION:When the focus error signal is inputted to a window comparator 9 at the time of recording, a high level power-up signal is outputted by the window comparator 9 at the time when the focus error signal exceeds a threshold as shown in the Figure with a broken line. A recording data is formed on the optical disk 2 with the semiconductor laser 4 which is turned on and off by a laser driver with the driving current for recording in response to a recording data signal from a modulator 10. Then, when the high level power-up signal is inputted from the window comparator 9, the semiconductor laser 4 is turned on and off by a still higher level driving current. By this method, even when the laser spot becomes largely out of focus by a flaw of the optical disk or the vibration due to disturbance, the accurate recording can be performed because the light quantity of the semiconductor laser is increased.
