    摘要: A boring tool having a tool body (10) which has a pair of chip discharge flutes (11) formed in the peripheral surface thereof. A cutting edge (13) is formed on the edge line where the end relief surface of the tool body intersects the wall surface of each chip discharge flute which faces forwardly as viewed in the direction of the tool rotation. A first margin (15) is provided on the end of the land which is on the trailing side of the flute (11) as viewed in the tool rotation direction, while a second margin (17) is provided on the end of the land adjacent to the heel (16). The lands are provided with recesses (20) in the depths of each of which progressively increase from the first margin towards the second margin. A sub cutting edge (21) is formed on the edge line where the end relief surface meets the wall surface of the recess (20) which faces forwardly as viewed in the direction of the tool rotation.

    摘要: Novel styrene-based polymers and a process for efficient production thereof are disclosed. The styrene-based polymers have a branching nucleus represented by the general formula: R(S).sub.k or R(A-S).sub.k (wherein all the symbols are as defined in the appended claims), and have a sulfur content of 6 to 550 ppm, a weight average molecular weight of 450,000 to 1,300,000, and a weight average molecular weight/number average molecular weight (Mw/Mn) ratio of 2:1 to 15:1. The styrene-based polymers are greatly improved in impact resistance while maintaining sufficiently high fluidity and moldability and thus when injection or extrusion molded, can provide moldings having an excellent mechanical strength.

    摘要: A color photographic element contains a compound of the following formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represent hydrogen atom, or an alkyl or aryl group; Ar.sub.1 and Ar.sub.2 each represent an aryl group; and n and m each represent 1 or 2. The color element containing the above compound displays excellent sensitivity, gradation, and color-developability even when developing it with a color developer not substantially containing any benzyl alcohol.
