Title: Rolling-cutting tool
Inventor: TAKIGUCHI MASAHARU
IPC: B23C5/12
Filed: 1992-02-13
Abstract: PURPOSE:To prevent the concentration of chips near the edge of a main cutting edge and to sharply decrease the occurrence frequency of chip biting by forming the first side of a tip into a braker face extending over its overall length to obtain the long braker face without making the tip large-sized, and largely curling the chip at a position separated enough from the edge of the main cutting edge. CONSTITUTION:Since the first side of a tip is formed into a braker face 27 extending its overall length, a long braker face is obtained. Thus, a chip is largely curled at a position separated enough from the edge 28 of a main cutting edge to prevent the concentration of the chips near the edge of the main cutting edge. In addition, since the edge of the main cutting edge is severally formed at both the ends of the braker face of the first side of the tip, even when either of the edges of the main cutting edge is used, the chip is curled by directing the same braker face toward the direction of the rotation of a tool body 2. Thus, the formation of a recess such as the braker face on two other sides 25b, 25c adjacent to the braker face on the first side becomes unnecessary, and these sides are severally formed into an uniform flat face to increase a seating area between a tip seat and a tip.

Abstract: PURPOSE:To attain efficient coding while keeping picture quality high by applying different coding to a black line part and to other part. CONSTITUTION:A black edge such as a black letter or the like is discriminated for each block at first and the pattern is stored in a frame memory 4d. Then an average value (as to each component of R, G, B) of parts other than a black line picture is obtained from an input picture and a difference between the average value and the R, G, B component of the black line picture is subtracted together. The subtracted picture data R', G', B' are converted into a luminance component data Y and color component data U, N at an RGB-YUV conversion section 36 and stored respectively to frame memories 4a-4c. Then a conversion coefficient is obtained from the picture data inputted area sequentially as Y,U,V at an orthogonal conversion coding section 8. Then the pattern information stored in a frame memory 4d is coded by a pattern coding section 7 and sent to a coding data transmission section 9. Thus, the quality of the black line picture is kept.
