摘要:
Disclosed is a production method of an aluminum support for a lithographic printing plate, capable of stable and low-cost production of an aluminum support for a lithographic printing plate, the support being scarcely subject to generation of treatment unevenness called streaks or grainy unevenness ascribable to the different in the aluminum dissolving rate due to the difference in the orientation of the crystal grain. The aluminum support is produced by surface graining and then polishing an aluminum plate or by polishing an aluminum plate while etching it in an aqueous acid or alkali solution. The aluminum plate may be subjected to polishing and then to anodization or may be subjected to polishing, to surface graining, again to or not to polishing and then to anodization. A production method for producing a high-quality support for a lithographic printing plate, free of local unevenness is also disclosed.

摘要:
A rotating preparatory abrasion roller finely abrades the surface of a web, which is to be a support of a lithographic plate, in preparatory abrading prior to main graining for graining the surface of the web. The preparatory abrasion roller, which is arranged against one surface of the running web, is pressed into an interval between a pair of supporting rollers, which are arranged at a predetermined interval against the other surface of the web. Consequently, the surface of the web is finely abraded in contact with a relatively large area on the surface of the preparatory abrasion roller in the state wherein the web laps with the part of the preparatory abrasion roller.

An information coding apparatus, an information decoding apparatus, and a method and a program therefor are provided, which can represent a large amount of information with a small number of pixels. Information bits which are inputted are coded as a block of a two-dimensional image made up from m (where m is a natural number)×n (where n is a natural number) pixels. Specifically, pixels which represent the information bits are arranged in a code area, which is an area of (m−o)×(n−p) pixels within a code block of m×n pixels (where o and p are natural numbers which satisfy 0

摘要:
A blade sleeve 5 having an annular cutting edge 6 is formed at the distal end of a handle 1. A pressing body 9 is received in the blade sleeve 5 such that the pressing body 9 is allowed to move in the axial direction C. A contact portion 12 is formed at the distal end of the pressing body 9. The contact portion 12 may be located at a retracted position separated inwardly from the cutting edge 6 and a projected position F to which the pressing body 9 is moved from the retracted position, toward the cutting edge 6. When located at the projected position F, the contact portion 12 of the pressing body 9 is projected outward from the cutting edge 6. The pressing body 9 is movable between the retracted position and the projected position F and may be maintained at the retracted position or the projected position F. With the pressing body 9 maintained at the projected position F, a sample SE may be easily removed from the contact portion 12. By projecting from the cutting edge 6 at the projected position F, the contact portion 12 prevents the cutting edge 6 from being damaged, thus protecting the cutting edge 6.
摘要:
A hand tool includes a holder and a movable head portion to which a blade body is secured. The movable head portion is supported by the holder in a manner movable relative to the holder between an accommodated state Q, in which the movable head portion is accommodated in the holder together with the blade body, and a projected state, in which the blade body is projected from the holder. The orientation N of the blade body in the accommodated state Q and the orientation N of the blade body in the projected state are different from each other. This improves operation of the blade body both in the accommodated state Q and the projected state and reduces the size of a front opening of the holder to provide a compact holder of the hand tool such as a medical edged tool.
摘要:
An excision instrument includes a blade 2 mounted on the back surface of an elastic member 5 provided between gripping extensions 3, and is used by bringing the gripping extensions 3 close to each other to curve the elastic member 5 together with the blade 2 and by putting the convex surface produced on the blade 2 in a portion-to-be-removed. In the top surface of the elastic member 5, a plurality of slits 8, 9 and 10 are provided, and a plurality of projections 11 are provided between the slits 8, 9 and 10 so that contact parts 11a of the projections 11 are brought close to and into contact with each other via the slits 8, 9 and 10 when the elastic member 5 is curved. The contact parts 11a function as a curvature restricting part for restricting the curvature of the elastic member 5 or a flexural rigidity changing part for changing the flexural rigidity of the elastic member 5.
