摘要： A mold for forming a golf ball makes it possible to form minute dimples, and to improve mold release properties of the mold and wettability of the mold by a material when a urethane material is used for a cover layer. A mold according to the present invention is a mold for forming a urethane cover as an outermost layer of a golf ball, and includes: at least two split molds that are separably joined with each other, and that includes a cavity formed therein by the joining, the cavity being for forming the urethane cover; protrusions that are formed on a cavity surface of the split molds to form dimples of the golf ball; and a composite plating film that covers the cavity surface of the split molds, that comes into contact with a material of the urethane cover, and that contains a nickel-based matrix and fluororesin particles dispersed in the nickel-based matrix.

摘要： Present invention provides an optical encoder capable of improving the precision of an interpolation angle in a single signal track, in an encoder of sine-wave angle interpolation type. The optical encoder includes a waveform, in which a phase-modulated wave is superimposed in a predetermined period over a sine-wave of a fundamental period, as a signal track (103), and an optical detector (104) for extracting the sine signal and the cosine signal of the phase-modulated wave. An operation unit (106) operates electric angles individually from the output signals of a first optical detector pair and a second optical detector pair belonging to the optical detector, and determines the sum and difference of the electric angles, thereby acquiring the electric angle and the phase-modulated wave of the fundamental period.
