Title: Filter device for fine grain dispersion system
Inventor: NISHIMURA FUJIO
IPC: B01D29/11
Filed: 1979-06-29
Abstract: PURPOSE: To decrease clogging of a filter and perform filtration of good efficiency by providing a settling tank on the fluid supply side for the precision filter.  
     CONSTITUTION: A settling tank 3 is provided right under a filter 2, and filter mediums 2A of 0.1W100μ nominal openings are provided in the filter 2. An inflow port 4 from the side and an efflux port 5 positioned in the upper perpendicular direction in the flow direction from the inflow port 4 are provided to the settling tank 3. The efflux port 5 of the tank 3 and the inflow port 6 of the filter 2 are mounted freely and detachably by way of flanges 7, 8. The ascending velocity of fluid in horizontal section is made lower than the sedimentation velocity of the materials to be filtered by making computation by commonly known Steiner formula. Fluid enters the inside of the tank 3 through the inflow port 4 and large particles settle here. Only the small particles are sent into the filter 2 through the  efflux port 5. In the filter 2, the fluid is subjected to precision filtration, but it has  been removed of most of the large particles in the tank 3 and therefore the clogging  of the filter is less and even if the filtration area of the filter 2 is small, the filtration  of good efficiency may be performed.

Abstract: PURPOSE:To obtain the highly accurate coordinate input information despite the unsatisfactory linearity of the surface resistance and also to secure the high reading accuracy even with use of an inexpensive 8-bit A/D converter by providing plural intermediate electrodes on each coordinate input sheet. CONSTITUTION:The surface resistances 1La and 1Lb are formed to the coordinate input sheets 10A and 10B for detection of X and Y coordinate positions respectively on a sheet surface secured between the oposed electrodes 12 and 13. The intermediate electrodes 11a - 11c which are parallel to the electrode 13 are provided on the sheet surfaces of those surface resistance parts. When X/Y coordinates are detected at an input point P, the input signal is switched under the control of a CPU via a switch connection circuit, a switch circuit, a differential amplifier, etc., and inputted to an A/D converter as an analog signal. In this case, both resistances 1La and 1Lb are divided into plural pieces by electrodes 11a - 11c. As a result, the high reading accuracy is secured despite the unsatisfactory linearity of the surface resistance. At the same time, the high resolution is secured even with an inexpensive 8-bit A/D converter. Thus the information detecting ability is improved at a low cost.

Filed: 1981-05-29
Abstract: PURPOSE: To provide an aq. sealing material compsn. exhibiting low modulus and high elongation, containing an ethylene/vinyl acetate copolymer emulsion, a phthalate plasticizer and an inorg. filler.  
     CONSTITUTION: An aq. sealing material composition contains a synthetic resin emulsion consisting mainly of an emulsion of an ethylene/vinyl acetate copolymer having an ethylene content of 10W30wt%, a plasticizer consisting mainly of a phthalate plasticizer and an inorg. filler. When the ethylene content of the ethylene/vinyl acetate copolymer is less than 10wt%, alkali resistance and adhesiveness are insufficient. When the ethylene content exceeds 30wt%, the compsn. becomes too viscous. As said ethylene/vinyl acetate copolymer emulsion, emulsions which have a K-value of less than 75, particularly 50W74 and have not been conventionally used can be used. By using these emulsions, preferred results can be obtd. from the viewpoints of low modulus and high elongation.
