Title: Assembled hollow fiber membrane module container and its cleaning
Inventor: ADACHI TETSURO
IPC: B01D63/04
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To enable retention of high membrane performance and make it possible to treat a large amount of a solution containing a high concentration of a turbid substance by mounting in a single container a plurality of external pressure hollow fiber membrane modules each having one end of a hollow fiber membrane fixed and another end thereof set free in such a manner that the free end is arranged upward vertically. SOLUTION: A module container 80 is installed in such a manner that a raw water inlet 86 is oriented downward vertically and an air vent 88 is oriented upward. Raw water is allowed to flow downward along a hollow fiber membrane in a module 81 through the raw water inlet 86, and is filtered. Then, refined permeation water is introduced into a permeation chamber of the module 81 and is extracted from an outlet 90 through an extraction pipe 72 and a joining pipe 87. The module 81 is constituted of a cylinder 83 penetrating a flat plate 82 secured to an opened end face of a main body 13 and a header 85 connected to a seat 84 jointed with the cylinder 83, and the follow fiber membrane is included within the cylinder 83 in a state wherein a free end thereof is oriented upward. Thus, adhesion of a solid matter onto the hollow fiber membrane is suppressed.

IPC: G03G15/01
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent the life of the waste toner container, etc., of a first color cartridge from getting shorter and to save the needless exchange of the waste toner container so as to stably form an image in the case of recovering toner left after secondary transfer on an intermediate transfer body by a 1st image carrier in an image forming device where a plurality of cartridges constituted by combining the waste toner container with an image forming means including the 1st image carrier are arranged along the intermediate transfer body. SOLUTION: The toner left after the secondary transfer remaining on an intermediate transfer belt 10 by the secondary transfer to transfer material 13 is electrified to have a polarity reverse to the primary electrifying polarity of a photoreceptor drum by a toner electrifying roller 9, whereby most of the toner is stuck to the photoreceptor drum 1K of the first color cartridge 20K out of the cartridges 20K to 20C arranged on the belt 10, removed by a blade 5K and recovered in the waste toner container 6K. By setting the transfer efficiency to 90% in the primary transfer and the secondary transfer, the toner amount becomes about 4.6 times as high as that of the second and succeeding color cartridges, so that the capacity of the container 6K is set five time as high as that of the second and succeeding color cartridges.

Title: Coated optical fiber
Inventor: HOSOYA TOSHIFUMI
IPC: C03C25/10
Filed: 1989-06-28
Abstract: PURPOSE:To prevent the increase of the transmission loss by specifically conditioning the clamping force in the radial direction due to a protective layer with which the outer periphery of an optical fiber is coated. CONSTITUTION:When a glass fiber 1 is pulled out, the inside diameter is changed to obtain a protective layer 3' having an inside diameter d' since the contracting force acts on a protective layer 3 inward or outward. In this case, -0.05kg<=Fapprox.=+0.05kg is set where F is the clamping force of the protective layer and is defined as F=(the sectional area of the protective layer)X(the Young's modulus of the protective layer)X(the inside diameter contraction rate of the protective layer). When F is a positive value, the protective layer clamps the optical fiber inward to apply the distortion to the optical fiber; and when F is a negative value, the protective layer pulls the optical fiber outward to apply the distortion to the optical fiber. These forces are applied in opposite directions, but the distortion given to the glass is the same is quality. Thus, the increase of the transmission loss is reduced.
