Title: Method for backwashing ceramic membrane
Inventor: YONEKAWA HITOSHI
IPC: B01D65/02
Filed: 1993-12-24
Abstract: PURPOSE:To provide a sufficient effective membrane differential pressure and to effectively backwash a ceramic membrane in a short time by closing the membrane on the raw water side, exerting a high pressure from the filtration side to equalize the pressures on the raw water side and filtration side of the membrane and then releasing the pressure on the raw water side at a time. CONSTITUTION:When backwashing is needed, a raw water feed valve 3, a waste backwashing water valve 9, etc., are closed to close the raw water side. High-pressure air is added to a pressure tank 5 under these conditions by opening a high-pressure air feed valve 6, hence a pressure is exerted on the filtration side of a ceramic membrane 2, the pressure is transmitted to the closed raw water side, and the pressures on the raw water side and filtration side of the membrane 2 are equalized. While the valve 6 is opened and the valve 9 is rapidly opened, the pressure on the raw water side is lowered at once, and a large effective membrane differential pressure is generated. Accordingly, the deposits on the membrane surface are successively peeled off the surface, passed through the valve 9 along with the filtered water flowing out of the tank 5 and discharged.

Inventor: SHIMAZAKI SHINYA
IPC: H01K7/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent the glare given to a vehicle running in the opposite direction without switching a headlamp to a low beam by forming the upper side required region of the lens of the headlamp into a ground glass state. SOLUTION: The upper side required region 2 of the lens 1 of a headlamp, i.e., the region of the range that no glare is given to a vehicle running in the opposite direction during a travel by it with a high beam, is formed into a ground glass state by machining. The light of the high beam emitted from a light source, passing through the upper side required region 2 through a reflecting mirror 3 and irradiating the front, is diffused and the blare to the vehicle running in the opposite direction disappears. The ground glass machining may be set to such degree that the glare can be reduced to sufficiently secure safety for the vehicle running in the opposite direction, and the headlamp may have sufficient brightness to reach a sufficiently far distance.

Abstract: PURPOSE:To execute the measurement at high speed and with high reliability by extracting an end point by comparing a difference value and a threshold in each position of height information of an object, based on three-dimensional coordinates of the object, and obtaining exactly a step difference and the dimension of a clearance which the object has by a small operation quantity.

Subsequently, from a coordinate arithmetic part 4 in a position in which the slit light L is projected, three-dimensional coordinates (Y, Z) of a bumper being an object to be measured and a reference block are obtained. Also, in the arithmetic part 4 the center position of the slit light is detected with high accuracy by deriving the centroid of its reflecting signal intensity at every scanning line, in an optical cut image projected to the object and obtained by executing an image pickup by a television camera 2. In such a way, from the center position of the obtained slit light and the positions of the camera 2 and the light source 1, three-dimensional coordinates (Y, Z) are detected by the principle of a trigonometrical survey.

Abstract: PURPOSE:To easily obtain a wafer having favorable flatness by sticking plural semiconductor wafers to a freely rotatable polishing block and setting the outside diameter of abrasive cloth on a polishing level block where the wafers are brought into sliding contact smaller than the range of the total moving locus of the semiconductor wafer. CONSTITUTION:A circular abrasive cloth 2 is stuck all over the surface of a freely rotatable disc-like polishing level block 3, and plural, for example, four semiconductor wafers 1 are stuck to a disc-like polishing block 4 capable of freely rotating round a shaft different from that of the polishing level block 3. At this time, the outside diameter of the polishing cloth 2 on the polishing level block 3 is set smaller than the range of the total moving locus of the semiconductor wafers 1 so that a part of the polishing block 4 is projected outside over the polishing level block 3. Thus, a difference is produced in the sliding travel of the wafer 1 to the abrasive cloth 2 to restrain depletion of a wafer part positioned in the peripheral part of the polishing block 4. In a polishing work, the polishing level block 3 and the polishing block 4 are rotated while supplying abrasive liquid 7 so as to polish the wafers 1.
