Abstract: The object of the present invention is to provide a method for producing fine fibers and a sheet containing fine fibers, whereby fiber refinement (fibrillating) of a fiber material is facilitated, freeness and dehydration performance of slurry containing fine fibers obtained after fiber refinement (fibrillating) is favorable and resistance to yellowing of the fine fibers is improved. The present invention provides a method for producing fine fibers, comprising at least the steps of: (a) introducing electrostatic and/or steric functional substituents into a fiber material to obtain substituent-introduced fibers; (b) subjecting the substituent-introduced fibers to mechanical treatment; and (c) eliminating some or all of introduced substituents from the substituent-introduced fine fibers obtained in step (b) to obtain fine fibers from which substituents have been eliminated.

Abstract: A coated paper for printing having a bulk density of 1.05 g/cm3 or less and two or more coating layers mainly composed of white pigments and adhesives formed on at least one side of a base paper which has a bulk density of 0.75 g/cm3 or less, wherein pigments of an undercoat in contact with an outermost coating layer comprises satin white of 1-30 mass % whose average particle diameter is within a range of 0.1-1.3 ?m measured pursuant to radiolucent particle size distribution measurement and other white pigments of 70-99 mass %, wherein an amount of the adhesives of the undercoat is within a range of 10-20 mass % based on 100 mass parts of pigment components.

Abstract: This invention provides a production process, which can stably produce high-quality satin white (calcium trisulfoaluminate) having very small and homogeneous particulate shapes suitable for incorporation into coated paper for printing, and an apparatus for use in said process. In this process for producing calcium trisulfoaluminate, a calcium hydroxide suspension (A) is reacted with an aqueous aluminum sulfate solution (B) to produce calcium trisulfoaluminate (C). The aqueous aluminum sulfate solution (B) is added in plurality of stages to the calcium hydroxide suspension (A). At least any one stage of the plurality of stages addition, addition of the aqueous aluminum sulfate solution (B) to the calcium hydroxide suspension (A) is carried out in such a manner that the aqueous aluminum sulfate solution (B) is continuously added to the calcium hydroxide suspension (A) being continuously transferred.

Abstract: A coated paper is white and glossy enough to give satisfaction as a printing paper, exhibits a good printability in offset sheet-fed printing and a high printing gloss, and does not degrade the print efficiency. The coated paper is characterized by having two or more coating layers composed mainly of a pigment and an adhesive on at least one side of a base paper. When ink is transferred onto the paper, the ink settability is relatively low in the early stage of the drying process and relatively high in the final stage.

Abstract: A distributed-processing equipment has a first storage means in which identifiers of first processors that reconfigures respective devices are registered in advance. When a second processor has detected an event for which one of the devices is reconfigured, the second processor notifies, of the event, a first processor indicated by an identifier that is registered in the first storage means as corresponding to the device. This distributed processing equipment can flexibly adapt to a variety of configurations at a low cost without changing the configuration greatly, whereby the performance and the reliability of an information processing system and a facility to which the invention is applied can be kept high in a stable manner.

Abstract: A mirror surface grinding method processes an optical glass material into a lens shape using a cup-shaped grinding stone. The grinding stone is pupplied with a polishing solution which contains charged fine particles, thereby electrically attaching the charged fine particles to the grinding stone. The grinding stone is rotated and moved relative to the optical glass material along a final shape to be generated from the optical glass material, thereby grinding an unnecessary portion of the optical glass material to remove it, using a peripheral face portion of the grinding stone, and at the same time polishing the final shape surface of the optical glass material using charged fine particles attached to an annular face portion of the rotating and moving grinding stone.

Abstract: A holding device for holding an optical element to be ground is arranged such that pressure applied to a receiving face of the optical element on the holder base is made different in the radial direction in order to eliminate deformation, positional deviation or inclination of the optical element due to grinding resistances during grinding or due to high-pressure grinding. An elastic member is employed as an elastic member, or a receiving member capable of absorbing the positional deviation, the inclination, or the like of the optical element during grinding thereof is used.

Abstract: A polishing work holder for supporting a lens to be polished for use in a lens polishing machine is disclosed. The work holder comprises a holder body rotatably supported by a housing and having a recess portion formed on a rotating shaft of one end face thereof and a suction hole opened at the end face, a lens receptacle having a hole communicated with the suction hole to suck and hold a lens at one end surface, a spherical body intervened between the recess portion of the holder body and the lens holder so as to contact the another end face and for carrying the lens receptacle tiltably and movably in the crossing direction to the axis of the holder body, a fitting ring secured to the holder body concentrically and loosely fitted onto an outer periphery face of the lens or an outer periphery face of the lens receptacle so as to limit the tilting of the lens and the moving in the diametrical direction, and a sealing member provided between the holder body and the receptacle at outside of the suction hole.
