摘要:
Disclosed is a hydrogel contact lens which has improved and long-lasting wettability in the surface and inner structures, while exhibiting excellent contamination resistance, shape stability and mechanical strength. Also disclosed is a method for producing the hydrogel contact lens. The wettable hydrogel contact lens is characterized by containing an ionic hydrophilic polymer which is a compound having a hydroxy group and an anionic group. The method for producing a hydrogel contact lens is characterized in that a constituent component of the hydrogel contact lens is a copolymer containing at least a cationic monomer and an anionic monomer, and in that the method comprises a step wherein counter ions of the monomers form ionic bonds and a step wherein an ionic hydrophilic polymer, which is a compound having a hydroxy group and an anionic group, is contained.

The invention presents a beating technology of used paper processing apparatus of furniture size, capable of preventing leak or disclosure of confidential information, personal information or any other information securely and capable of holding a high confidentiality, that can be installed not only in a large office, but also in a small shop or general household. In the beating process of the beating unit (3) in the used paper processing apparatus of furniture size, by using at least one grinder (30) having beating action surfaces (31a, 32a) disposed oppositely across a tiny beating gap (G), and a pair of beating disks (31, 32) rotating relatively, the beating gap (G) of the beating action surfaces (31a, 32a) is controlled or adjusted to be narrower gradually from the beginning till the end of the beating process. As a result, a smooth and efficient beating operation is realized from the beginning till the end of the beating process.
摘要:
An abradant-containing eraser is disclosed which comprises an elastomer composition containing a matrix of a biomass plastic and crosslinked natural rubber particles dispersed like islands in the matrix of the biomass plastic, and an abradant. According to the present invention, it is possible to provide an abradant-containing eraser using an elastomer composition, which can be recycled, is friendly to the environment, and corresponds to the recycling society, without relying on fossil resources.
摘要:
A used paper recycling apparatus being installed in a room of a small shop or the like, friendly to the environment, low in running cost, and capable of maintaining a high confidentiality. The apparatus includes, in an apparatus case (5) of furniture size, a pulp making section (2) for manufacturing used paper pulp (UPP) by macerating and mashing used paper, a paper making section (3) for manufacturing recycled paper (RP) by making the used paper pulp (UPP) manufactured in the pulp making section (2), and a control section (4) for driving and controlling the pulp making section (2) and paper making section (3), in which the pulp making section (2) comprises a macerating unit (6) for macerating the used paper by agitating and tearing, and a mashing unit (7) for mashing the used paper macerated in the macerating unit (6), and the mashing machine (20) of the mashing unit (7); has mashing members rotating relatively being disposed oppositely across a slight mashing clearance, and the opposing faces of these mashing members cooperate to form a mashing action surface, and the used paper passing the mashing clearance is pressurized and mashed by the mashing action surface, and the inks forming characters and patterns on the used paper are pulverized
摘要:
The invention presents a paper machine for a used paper recycling apparatus being installed in a room of a small shop or the like, friendly to the environment, low in running cost, and capable of maintaining a high confidentiality. The paper machine (3) includes a paper making process unit (10) for manufacturing wet paper (RP 0 ) from slurry pulp suspension (PS) sent from the pulp making section (2) of a preceding process, and a drying process unit (12) for drying the wet paper (RP 0 ) manufactured in the paper making process unit (10) and making recycled paper (RP), in which a processing conveyor (15) is disposed between the paper making process unit (10) and the drying process unit (12) extending in the overall length of the paper making process and the drying process, and this processing conveyor (15) is manufactured in a form of net belt conveyor having a running mesh belt (20) of mesh structure composed of innumerable mesh cells for filtering and dewatering the pulp suspension (PS). In this configuration, it is not required to exchange the conveyors when changing the process of the manufactured wet paper from the paper making process to the drying process.
摘要:
In a used paper recycling apparatus of furniture size that can be installed in a small shop or room, this is a belt meandering preventive device of a simple structure for executing the paper making process for manufacturing used paper pulp at low trouble rate and high reliability. A rolling roller (140) rolls on a mesh belt (105) of a paper making net conveyor unit (95) for processing and conveying used paper pulp (UPP) while applying a tension a, roller oscillating unit (141) oscillates this rolling roller (140) in a direction intersecting with the running direction of the mesh belt (105), and the rolling rollers (140) is maintained at the neutral position so as to be perpendicular to the running direction of the mesh belt (105) when the running position of the mesh belt (105) is in an appropriate running range, and the rolling roller (140) is directed to a meandering correcting direction for moving the running position of the mesh belt (105) into the appropriate running range when the running position of the mesh belt (105) is out of the appropriate running range.
摘要:
A pulp supply device incorporated in a used paper recycling apparatus of furniture size capable to be installed at an originating source of used paper, being a device for composing the pulp supply section of a paper making device for producing recycled paper by processing used paper pulp manufactured in pulp making section in a preceding process, wherein the pulp supply device (47) has a structure spreading uniformly and supplying slurry pulp suspension (PS) containing water and used paper pulp sent from the pulp making section, on the surface of mesh endless belt (45) on which the paper making net conveyor runs.
