A workpiece holder for polishing comprising a workpiece holder body which is provided with multiple perforated holes for holding a workpiece by vacuum suction and a holder back plate which is closely contacted with a back face of the holder body and has grooves for vacuum, wherein the holder back plate is composed of a synthetic resin and has an Asker C hardness of 70 or higher but lower than 98, and an apparatus for polishing a workpiece and a method for polishing a workpiece utilizing it. By improving the material of holder back plate of a workpiece holder for polishing that holds a workpiece by vacuum suction to enhance sealing with the holder body, thereby developing such a holder back plate that should not transfer deformation of the holder body to the workpiece surface, even if polishing agent slurry is introduced and solidified, to provide a workpiece holder for polishing having a workpiece holding surface of high precision, an apparatus for polishing a workpiece and a method for polishing a workpiece.
摘要:
The present invention is a workpiece holder for polishing comprising at least a workpiece holder body having multiple perforated holes for holding a workpiece by vacuum adsorption and a back plate disposed on the back side of the body, which is provided with temperature controlling means or cooling means for the holder body. Thus, there is provided a workpiece holder for polishing, a polishing apparatus and a polishing method, which can provide a workpiece having good flatness by suppressing thermal deformation of the workpiece holder body and deformation of a resin film coated on the workpiece holding surface without degrading flatness of a workpiece held on the workpiece holder in the polishing of the workpiece, even when the number of polishing operation increases.

By improving the material of workpiece holder body of a workpiece holder for polishing that holds a workpiece by vacuum adsorption, and the material of resin film for coating a workpiece holding surface of the holder, and developing a method for coating the surface with a resin, which does not cause blocking of perforated holes of the holder body with the resin during the resin coating process, there are provided a workpiece holder for polishing having a workpiece holding surface of high precision, and a method for producing it. According to the present invention, there are provided a workpiece holder for polishing having a workpiece holder body provided with multiple perforated holes for holding a workpiece by vacuum adsorption, wherein a holding surface of the holder body is coated with a coating film formed by applying a thermosetting resin on the holding surface and curing it with heating, and a surface of the coating film is polished, and a method for producing it.
摘要:
A hair cosmetic composition including (a) at least one compound selected from fatty acids containing a linear or branched alkyl or alkenyl group having 12-40 carbon atoms, salts thereof and fatty acid esters composed of one of the fatty acids and a polyhydric alcohol; (b) at least one aromatic alcohol represented by the general formula (1): ##STR1## wherein R.sup.1 means a hydrogen atom or a methyl or methoxy group, Y denotes a single bond or a linear or branched alkylene or alkenylene group having 1-3 carbon atoms, Z is a hydrogen atom or a hydroxyl group, and p and q stand individually for a number of 0-5; and (c) at least one cationic surfactant. The hair cosmetic composition has neither sticky nor oily feel to the touch, is excellent in hair-conditioning effects of, for example, giving users a moistured feel of the hair and imparting softness and smoothness to the hair, gives resilience to the hair and is superb in effects of preventing damage to the hair and of keeping the waves or curls of the hair beautiful.
摘要:
The present invention relates to a hair cuticle caring method or volume enhancing method, which comprises treating hair with a composition containing (A) a cationic surfactant and (B) an organic acid or salt thereof in a combination to give, when an aqueous solution containing 1 mM of each of the components is formed, 40 mN/m or less as the surface tension of the aqueous solution at 27±0.5° C. By the application of the above-described composition, the lift-up of the hair cuticle can be suppressed, the volume can be enhanced softly, moisturized but stickiness-free feeling is imparted and styling ease is improved.
