摘要:
The present invention aims at providing: a recycling usable regenerated particle aggregate; a method for allowing stable manufacture of the regenerated particle aggregate; a paper containing the regenerated particle aggregate, the paper exhibiting excellent property in case of newsprint papers, printing papers, book printing papers, and electrophotographic printing papers that use the regenerated particle aggregate, and especially a neutralized paper containing the regenerated particle aggregate; and a coated paper for printing having especially excellent printability, using the regenerated particle aggregate. Problems will be solved by: a regenerated particle aggregate obtained through dehydration, drying, calcination, and pulverization using a deinked froth discharged at a used paper deinking treatment process as a main raw material; a method for manufacturing the regenerated particle aggregate; a paper containing the regenerated particle aggregate as an internal filler; a coated paper for printing having a coating of the regenerated particle aggregate as a pigment for coating.

A split outer ring of a split rolling bearing, which splits in a radial direction, includes a pair of split outer ring members which are each formed into a semi-cylindrical shape and which are formed into a cylindrical shape by being butted against each other at circumferential end portions. A pair of first flat plane portions which extend from both axial end edges of the end portions towards a center in parallel with an axis and a V-shaped recess portion, positioned between the first flat plane portions and is recessed in a circumferential direction relative to the pair of first flat plane portions, are formed at one end portion of the circumferential end portions which are butted against each other, and a pair of second flat plane portions which extend from the both axial end edges in parallel with the axis.

A bearing apparatus includes two split outer ring halves disposed in close contact with each other and a plurality of rollers. A circumferential end of each of the split outer ring halves has a concave-and-convex shape including a first slope portion inclined with respect to a line extending along an axial direction of the split outer ring halves and a second slope portion inclined in an opposite direction to that of the first slope portion. Each of the rollers is provided with crowning so as to be shaped in barrel form, and an amount of crowning is set such that an apex of a projecting portion at the concave-and-convex shape of each of the split outer ring halves is located on an axially outer side of a rolling surface of the roller rolling on an inner peripheral surface of each of the split outer ring halves.

A catalyst-aided chemical processing method can process hard-to-process materials, especially SiC, GaN, etc. whose importance as electronic device materials is increasing these days, with high processing efficiency and high precision even for a space wavelength range of not less than several tens of μm. The catalyst-aided chemical processing method comprises: putting a workpiece in a processing liquid in which halogen-containing molecules are dissolved; and moving the workpiece and a catalyst composed of molybdenum or a molybdenum compound relative to each other while keeping the catalyst in contact with or close proximity to a surface to be processed of the workpiece, thereby processing the surface of the workpiece.

There is provided a rolling bearing including an inner ring having an inner ring raceway surface, an outer ring having an outer ring raceway surface and a shoulder portion formed on one axial side of the outer ring raceway surface, a plurality of rolling elements which roll between the inner ring raceway surface and the outer ring raceway surface, and a cage adapted to hold the plurality of rolling elements at predetermined intervals in a circumferential direction and having a guided surface which confronts the shoulder portion of the outer ring in such a manner as to be brought into sliding contact therewith. The rotation of the cage is guided through sliding contact of the guided surface of the cage with a guiding surface of the shoulder portion of the outer ring. A guiding space which is a radial space between the guiding surface of the shoulder portion of the outer ring and the guided surface of the cage is made to increase as approaching the rolling elements.

A flattening method, by utilizing the advantages of the CARE method and making up for the disadvantages, can perform removal processing of a surface of a workpiece at a sufficient processing rate and can provide a processed surface having enhanced flatness without leaving damage in the processed surface. A flattening method comprises at least two surface removal steps and at least two cleaning steps, the final surface removal step being a catalyst-referred etching step comprising immersing a workpiece in a processing solution containing at least one of hydrohalic acid, hydrogen peroxide water and ozone water, and bringing a surface of a catalyst platen into contact with or close proximity to a surface to be processed of the workpiece to process the surface, said catalyst platen having in a surface a catalyst selected from the group consisting of platinum, gold, a ceramic solid catalyst, a transition metal, glass, and an acidic or basic solid catalyst.

A bearing apparatus includes: two split outer ring halves which includes outer ring raceway surfaces and are disposed within a supporting hole of the housing, respectively; and a plurality of rollers which are disposed on respective inner surfaces of the both split outer ring halves and supports a shaft. Each of the two split outer ring halves includes an oil hole penetrating the split outer ring half in a radial direction thereof and an oil groove formed on an outer diameter surface of the split outer ring half along a circumferential direction thereof to allow the oiling passage and the oil holes to communicate with each other. Each of the oil holes is disposed at a position located at an angle of within 45° from the joint surface of the split outer ring halves in an opposite direction to a rotating direction of the shaft.
