  • Patent number: 6221267
    Abstract: Spinnable balls each having two surfaces with different optical characteristics can be produced by forming a plurality of balls with the same specific gravity on a thermoplastic film, and softening the thermoplastic film by controlling a heating temperature thereof based on the specific gravity of the balls so that the hemispheres of the balls are embedded into the thermoplastic film by their own weight. A layer having different optical characteristics from those of the balls is then formed on the exposed surface of each ball.

  • Patent number: 5568295
    Abstract: A liquid crystal device is constituted by a pair of substrates, and a chiral smectic liquid crystal assuming at least two stable states disposed between the two substrates. At least one of the substrates is subjected to a uniaxial aligning treatment in two directions including a normal direction and a reverse direction substantially opposite to the normal direction. The liquid crystal is placed in an alignment state such that the liquid crystal provides an apparent tilt angle .theta.a which is a half of an angle between said two stable states, a tilt angle H and a pretilt angle .alpha. with respect to a substrate surface, and forms smectic layers forming an inclination angle .delta. from a normal to the substrate surfaces satisfying: H/2<.theta.a.ltoreq.H and H>.alpha.+.delta.. According to the liquid crystal device, an undesirable liquid crystal molecular movement along the substrates is effectively suppressed.

  • Patent number: 5535185
    Abstract: An information recording/reproduction is performed as follows on a recording medium using a probe. A distance between the probe and a recording layer of the recording medium is controlled, and relative movement of the probe and the medium is effected so that the probe scans a surface of the recording layer. Recording bits corresponding to information is recorded or erased on the recording layer under a predetermined recording/erasing condition. The information is reproduced from the recording bits produced on the recording layer upon detection of a physical quantity such as a tunneling current, an electric field radiation current and the like generated between the probe and the recording layer. A characteristic/state such as an electrical characteristic, a surface state and the like of the recording layer is detected. The recording/erasing condition is corrected on the basis of the detected characteristic/state of the recording layer.
