  • 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. Finally, the balls provided with the layers are detached from the thermoplastic film.

  • 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.
