Title: Method for deinking waste paper
Inventor: HIRAKOUCHI YOSHIE
IPC: D21C5/02
Filed: 1993-02-25
Abstract: PURPOSE:To readily obtain recycled paper of high whiteness by using a deinking agent having a higher cloud point than the flotation treating temperature and a deinking agent having a lower cloud point than that, subjecting printed waste paper to the flotation treatment and efficiently peeling the ink from the printed waste paper in disintegration. CONSTITUTION:Printed waste paper which is a raw material is cut to 3X3cm size and placed in a pulp disintegrator. Caustic soda in an amount of 1.0% based on the weight of the raw material printed waste paper, sodium silicate No.3 in an amount of 3.5% based on the weight of the raw material printed waste paper, hydrogen peroxide in an amount of 1.0% (active component) based on the weight of the raw material printed waste paper, a deinking agent having a higher cloud point than the flotation treating temperature (e.g. polyethylene glycol monostearyl ether) and a deinking agent having a lower cloud point than the flotation treating temperature (e.g. lauryloxy- polypropylene oxide-polyethylene oxide-polypropylene oxide-block polymer) are used in combination and hot water is added so as to provide 5% pulp concentration. The disintegrating treatment is then carried out at 35 deg.C and the flotation treatment is performed at 30-50 deg.C to prepare a pulp sheet. Thereby, the recycled pulp of high whiteness with hardly any residual ink is efficiently obtained.

Filed: 1984-02-28
Abstract: PURPOSE:To read out characters of which intervals are not fixed by finding out a circumscribed frame from the right and left, and upper and lower end parts of a character pattern, determining the segmenting areas of the character pattern and transferring the areas to a character pattern memory. CONSTITUTION:A character image is inputted to a line buffer 6b through an input part 6a. The entered block is accessed from the left end successively in the descending direction by a line buffer control part 6d and images on the line buffer 6b are successively checked by a black point detecting part 6e. At the time of a scanning line 6, the first black point is detected and the position X1 becomes the circumscribed frame on the left side. To find out the right circumscribed frame, scanning is continued up to a scanning line 10 detecting one white row and the row X2 arranged immediately before the scanning line becomes the right circumscribed frame. At the time of finding the right circumscribed frame, the image of the line buffer 6b is transmitted also to a projected information forming part 6f, so that the projected information of the lateral pattern is formed. If it is defined that the upper end and lower end of the projected information are Y1, Y2 respectively, a part surrounded by positions X1, X2, Y1, Y2 is detected by a character pattern area detecting part 6j.

Abstract: PURPOSE:To prevent adhering of a fiber sheet and a water absorptive layer by moisture even if this running water preventive material is preserved in a rolled state by forming a water absorptive layer and a easily water-soluble sealing layer via a fiber sheet layer. CONSTITUTION:This running water preventive material 1 is provided in order to prevent running water in the event of infiltration of water into an optical fiber cable, etc., and is constituted by forming the water absorptive layer 2 consisting of a highly water absorptive resin and a rubber binder on one surface of the fiber sheet layer 3 and the easily water-soluble sealing layer 4 on the other surface. Woven, knitted and non-woven fabrics, etc., are used as the fiber sheet. For example, crosslinked polycrylate, starch, acrylic acid graft polymer, etc., are used as the highly water absorptive resin. Styrene butadiene rubber, butadiene rubber, etc., are used as the rubber binder. For example, resins, such as polyvinyl alcohol, are adequate as the sealing layer. As a result, the highly water absorptive resin and rubber binder of the water absorptive layer 2 do not leak from the other surface and, therefore, the problems of adhering at the time of storage do not arise at all.

Abstract: PURPOSE: To form fine patterns without leaving the material to be etched in step parts and fine the wirings formed on a substrare by applying anisotropic etching treatment to the substrate after isotropic etching.  
     CONSTITUTION: In the production of semiconductor devices, etc., an insulation film 22 is deposited on a substrate 21 of Si or the like except the opening holes for taking-out of electrodes, and Al is deposited on the film 22. A photoresist pattern 24 is formed on said Al 23, and is isotropically etched in a soln. consisting essentially of phosphoric acid or the like. Next, the Al 23 is anisotropically etched down to the substrate 21 by using plasma etching of parallel flat plate type. The residual material to be etched in the step parts is removed by this treatment method without impairing the high working accuracy intrinsic to an anisotropic etching method. Hence, the fine patterns are formed irrespective of the ruggedness of the substrate.

By connecting a first on-off valve 54 and a second on-off valve 49 in tandem and, at the same time, guiding the pressure liquid of the liquid supplying source 43 to the outlet 54b side of the first on-off valve 54, pressures at the inlet 54a and at the outlet 54b of the first on-off valve 54 are made equal to each other, resulting in preventing the unexpected leakage at the first on-off valve 54 due to the difference between the pressures at the inlet 54a and at the outlet 54b from occurring. On the other hand, let the slight set amount of the liquid leaked between the outlet 54b of the first on-off valve 54 and the inlet 49a of a second on-off valve 49. As a result, the amount of leakage of the liquid in the circulating passage can be controlled and the first and the second on-off valves 54 and 49 can be cooled.
