Abstract: Abstract Circular saw blades are provided on their outer periphery with saw tips (1) having hard-metal teeth (2), a centrally located mounting hole (5), and a plurality of cutter slots (12', 12'') that are in each instance arranged in different areas of the diameter of the blade, and cutter bars (8) of hard metal, high performance high-speed steel or tool steel, that are arranged on the trailing edges, relative to the direction of rotation of the blade, of these slots.    In order to create a circular-saw blade in a manner that saves material, that permits the production of very narrow kerfs, and yet is sufficiently stable or stiff, the cutter bars are configured with support bars (8) that extend at both ends beyond the trailing edges of the cutter slots and which are rigidly joined to those points of the saw blade that are covered by the support ends.  It is a particular advantage if the inner cutter slots (12', 12'') become wider to the outside, in a radial direction, and in particular are of a wedge shape.            (Figure 8).

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a Galois field arithmetic logic unit of a code error check/ correct apparatus to be employed when recording/ reproducing data on an optical disk.  The arithmetic logic unit uses a combination including a parallel multiplication circuitry of a primitive element .alpha. of a Galois field, an EX-OR addition circuitry for the multiplication results, a 0 element decision circuitry for the results of the addition, and resisters to which the multiplication results are fed back so as to accomplish a parallel computation of a polynomial, thereby enabling a root and an error value of an error location equation to be obtained at a high speed.  The arithmetic logic unit develops a remarkable reduction of the amount of computation particularly when the code system has a great code length and the degree of the error location polynomial associated with the long distance code is as high as d = 17.
