The 2nd strainer 9 is then opened to an outflow port side 2 in place of the 1st strainer to accept the flowing water and to start the effect of removing the foreign matter. A foreign matter discharge valve 13 provided nearer the outflow port 3 side than a boundary plate 8 is opened at the same instant, by which the flowing water past the 2nd strainer 9 is passed to the outflow port 3 side and part thereof is brought to the rear side so as to flow into the 1st strainer 7 from the outside periphery thereof and therefore, the foreign matter sticking to the outside periphery of the 1st strainer 7 is stripped. The stripped foreign matter is passed through the foreign matter discharge valve 13 and is extruded to the outside of a pipeline.

IPC: H01M10/48
Filed: 1989-03-31
Abstract: PURPOSE:To detect charge condition of a battery easily without requiring a special device by adding indicator chemical to electrolyte for changing the color of the electrolyte corresponding to its specific gravity. CONSTITUTION:When metanilic yellow is added to electrolyte as indicator chemical, for example, the electrolyte becomes red when chemical conversion is completed.

Title: Optical modulator
Inventor: SHIMIZU SHIGEO
IPC: G02F1/1333
Filed: 1990-03-29
Abstract: PURPOSE:To excellently improve the contrast ratio without any boosting in driving voltage to an optical modulating means which uses a high polymer liquid crystal compound material by providing a polarizing means and an analyzing means on the light incoming side and output side of the optical modulating means. CONSTITUTION:This optical modulator is equipped with the polarizing means 36 which polarizes incoming light and the analyzing means 38 which obtains a polarization- directional component by the polarizing means 36 among the rays of the modulated outgoing light. Namely, the light which is polarized by the polarizing means 36 is made incident on the optical modulating means 30, so the polarization state of the incoming light polarized is eliminated at the time of the scattering of the incoming light to the optical modulating means 30 and when the light whose polarization is eliminated is made incident on the analyzing means, its transparent quantity is reduced. Therefore, the quantity of transparent light of the whole optical modulator is varied greatly through the operation of the polarizer 36 and analyzer 38 according to whether or not the driving voltage is applied, so that the contrast is improved. Consequently, the contrast ratio can be improved excellently without any boosting in the driving voltage.

Title: Automatic running pump
Inventor: UMEDA AKINORI
IPC: F04D15/00
Filed: 1979-06-29
Abstract: PURPOSE: To prevent a trouble due to an invading extraneous substance, by starting a pump by a water level detector which acts at an upper water level and by stopping the pump by an electrical current detection relay which detects a load decrease due to the fall in the level of water.  
     CONSTITUTION: When the level of water rises to L 1 , a float switch 4 as a water level detector is turned on to start a pump 1. When the water level falls to L 0 , an electrical current detection relay R is turned off to stop the pump 1. Automatic operation is repeated between the upper and the lower water levels L 1 , L 0 . A ground pump may be used so that the front end opening of a water suction pipe is located at the lower water level. The float switch 4 as the water level detector is hung down into a vessel so that no troubles occure even if many extraneous matters invade into the vessel and a liquid surface in particular. The float switch is thus prevented from performing erroneous action.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To control the substrate potential of a memory cell array part independently without using triple well structure, and reduce the off leakage current of an access transistor, in a DRAM cell. SOLUTION: A memory cell array part A and a peripheral circuit part B are separated and isolated by a buried oxide film layer 7 within a trench 4, using an SOI substrate which has a p-type silicon single crystalline layer on a buried polysilicon layer 2b caught above and below between oxide film layers 2a and 2b.

Title: Dry type toner cleaning device
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/08
Filed: 1978-07-12
Abstract: PURPOSE: To perform efficient copying by selectively operating the cleaning device exclusive for an electrostatic latent image holding member and a developing means which also serves as a cleaning device according to copying operations.  
     CONSTITUTION: The cleaning brush 22 which is disposed between a transfer part 12 and a corona charger 2 is normally in the position spaced from a photosensitive drum 1. Each time when a copying start switch is pushed, it makes contact to the drum 1 for a fixed time, thereby cleaning the region where original image irradiation is accomplished. In addition, the bias voltage of a combined developing device and cleaning device 11 is normally held set at the higher one so as to operate as a cleaning device and only when the region of the drum 1 which has undergone oritinal irradiation comes, it operates as a developing device. Hence, when the start switch is pushed at the next time, cleaning of the drum 1 has already been done by the device 11 and even if the brush 22 makes contact to this, there is no more remaining toner, thus the clogging of the filter 23 and the wasteful consumption of the toner are prevented. Thereby, the copying process is made more efficient.
