    摘要: A system and method for determining the anisotropy of a sample of a light transmitting sheet is disclosed. The surface of the sample is irradiated with a polarized light which is directed through the sample to an analyzer element. The polarizing plane of the analyzer is matched to, or maintained in a predetermined angular relation to, the polarizing plane of the polarized light. The sample is rotated relative to the analyzer element so that the optical anisotropy can be determined from the relationship between the rotation angle and the output of measured light.

    摘要: There are disclosed a method and an apparatus for removing a cover from a golf ball. There is used a pair of geared rolls in an engaged manner, each geared roll comprising a cylindrical shaft on which teeth are axially formed and are circumferentially arranged at predetermined pitches. After the pair of geared rolls are rotated, the golf ball is placed on the upstream side of rotation of the geared rolls, so that part of the cover of the golf ball is bitten between the geared rolls. The cover bitten between the geared rolls is advanced by a rotational force of the geared rolls and is drawn out to the downstream side of rotation of the geared rolls. In this way, the core and cover of the golf ball are separated from each other. Accordingly, the cover can be mechanically removed from the golf ball with improved efficiency, so that the efficiency of work for recycling golf balls can be improved, and the amount of golf balls disposed as industrial waste can be reduced.

    摘要: A method and apparatus for measuring the orientation of the constituents of sheets are disclosed. The method comprises the steps of inserting a sheet into a small clearance with which the openings in a pair of waveguides are opposed to each other to form a cavity resonator, producing a relative motion at a constant speed between the sheet and the resonator while emitting linearly polarized microwaves from the upper waveguide to allow them to fall on the sheet at right angles thereto, measuring the amount of attenuation of the microwaves by the lower waveguide, and determining the orientation of the constituent of the sheet from that angle of the sheet with respect to the plane of polarization of the microwaves which gives the maximum attenuation.
