Abstract: PURPOSE:To make M pieces of image data selectable from N pieces of image data in its ascending order or descending order by operating N-1 pieces of data comparators in parallel and comparing N pieces of paired image data relatively in the time of N pieces of clock signals. CONSTITUTION:Sixteen pieces of data storage part 101-116 are connected in series and image data 1001-1016 are sequentially transferred.

Title: Milling device
Inventor: HABU RYOICHI
IPC: B23C3/12
Filed: 1994-09-30
Abstract: PURPOSE: To obtain an appropriate posture of a milling cutter by providing a support roller, which is mounted on the surface near the peripheral surface of a metallic plate, in such a manner that the roller moves up and down as if it is an integrated body with a cutter frame, so that the cutter frame copys the movement of a steel strip. CONSTITUTION: Since a support roller 17 rolls on an upper surface of a steel strip (A) under a constant pressure, the roller 17 acts, copying the wavy shape of the steel strip (A). As a result of this copying action, when a part of the steel strip (A), which is deformed upward in a projected mountainous form, passes the support roller (17) part, the cutter frame deforms upward. On the contrary, the part, which deforms downward, passes the support roller (17) part, the cutter frame 12 deforms downward. With this, the level of a milling cutter 13a of a cutter head 13 is held in such a way that the relative position of the cutter 13a to the steel strip (A) does not vary. Thus, milling operation can be carried out without partial contact of the peripheral surface of the milling cutter 13a.
