    摘要: A pair of semispherical molds, each having dimple-forming projections on a connecting portion is used to shape a resinous material into a golf ball having dimples on a seam corresponding to the connecting portion. A ball fixing means is utilized to hold the golf ball thereto with the seam uncovered. A cutting member disposed at an end of a rotary shaft, and having a radius of curvature smaller than a sectional radius of curvature of the dimple is utilized to remove a burr from the seam of the golf ball. The rotary shaft rotates on its axis and moves forward when the cutting member is brought into contact with the dimple on the seam and backward when the cutting member is brought into contact with a convex land portion. The cutting member is then pressed against the seam successively in alternate contact with the dimples and the land portions.

    摘要: An electronic circuit device decreases dispersion in the output of the circuit caused by changes in the resistance of the resistors resulting from stress. Resistor positions are selected on the circuit board so that a change in the circuit output caused by a change in resistance of a first resistor group becomes equal to a change caused by a change in resistance caused by a second resistor group, these changes being in opposite directions so as to cancel each other. Alternately, a plurality of resistors are connected to form a composite resistor such that the effect upon resistance of the composite resistor caused by the resistor having decreased resistance is cancelled by the effect upon resistance of the composite resistor caused by a resistor having an increased resistance.

    摘要: A golf ball has no great circles intersecting dimples. A method for manufacturing the golf ball uses the steps of molding the golf ball with a pair of semispherical molds having many dimple patterns formed on the inner surface thereof so as to form first dimples on the surface of the golf ball. Then a burr formed on the connecting portion between upper and lower molds is removed and dimples are subsequently formed and/or corrected on the connecting portion.

    摘要: A golf ball has one great circle and four one-half great circles which all intersect no dimples. Eight end points which include two end points of each one-half great circle are formed at the one great circle. These end points do not coincide with each other on the great circle. One of the one-half great circles intersects the other one-half great circle at a right angle at the middle point thereof on each of the great circle. In other words, an upper semispherical mold for an octahedral dimple golf ball arrangement is rotated a certain angle relative to the lower mold such that two of the three great circles are divided into four one-half great circles. The parting line of the mold becomes the one remaining great circle. In this manner, a more uniform flight of the golf ball canbe obtained regardless of whether the ball is hit on a seam, semi-seam of non-seam area.

    摘要: A golf ball which includes a spherical surface circumscribing a cubic octahedron, eight spherical triangles (4) and six sperical squares (5) divided by imaginary lines obtained by projecting edge lines (3) of the cubic octahedron (2) onto the spherical surface, and dimples (D) arranged within the spherical triangles (4) and the spherical squares (5) approximately equally and in point or line symmetry without intersecting the imaginary lines, with the total number of the dimples (D) being set in a range of 300 to 600 pieces, and one zone (6A) of great circle zones (6) obtained by connecting the imaginary lines being adapted to coincide with a parting line of a split metallic mold.
