    摘要: The tool comprises a shaft (18), and a shank (20). The shank (20) is grooved to define reducing elements (24) which may either lie in parallel planes normal to the axis of the shank (20) or on a helix. The groove (25) between adjacent reducing elements (24) has a rounded bottom wall (29) to reduce the accumulation of debris and to avoid weakening of the shank (20). A coating of abrasive material is applied to the reducing elements (24) to form an efficient cutting surface.

    摘要: This invention relates to a memory control circuit having a plurality of address groups and a plurality of bit groups running in rows and columns to form a matrix, and a plurality of memory cells (30', 32'...40') disposed at the intersection of the matrix.
    With a view to providing such a circuit in which two or more memory cells may be selected simutaneously for writing and reading purposes, each cell is connected to a plurality of address lines (10a, 10'a) and a plurality of bit lines (20c, 20'c). A first peripheral control unit (50) selects the first address and bit lines in response to a first control signal and a second peripheral control unit (50') selects the second address and bit lines in response to a second control signal.

    摘要: The implant is formed of a glass optic (12) which is piano-convex, its posterior surface being curved. The optic (10) is mounted in a haptic (14) which comprises two sets of flat feet (16) lying in the same plane as one another. The optic (14) has fenestrations (22) to enhance the circulation offluid in the anterior chamber. The haptic is formed either of a metal such as titanium or of an autoclavable clinically inert thermoplastic material such as a polyethersulphone.
