Abstract: A thermoplastic film that can be applied to various skin-engaging portions (e.g., the nose pads and/or earpieces) of a pair of eyeglasses to prevent slippage of the eyeglasses. The thermoplastic film comprises a composition that reacts to the wearer's body heat to become sticky. The resultant bond with the wearer's skin is sufficiently strong so as to prevent the pair of eyeglasses from slipping due to sudden movement, and is resistant to perspiration, oil or the like.

Abstract: A process for producing a polymer or a crosslinked article having a region in which the polymerization rate or crosslinking rate is varied is disclosed, comprising irradiating a photopolymerizable substance or photo-crosslinkable substance with laser light having an uneven distribution of intensity. The process is suitable for mass production of polymerization rate- or crosslinking rate-distributed articles. An arbitrary distribution pattern can be designed and formed under good control, and distribution regions having a fine shape can be formed with excellent precision. A plurality of distribution regions having a regular shape can be formed at a high density with high precision.

Abstract: A birefringent film in which molecules oriented in a direction parallel to the film plane and molecules oriented in the direction of the thickness of the film are present in a mixed state. Also, a process for producing the birefringent film, which comprises laminating a resin film on one or both sides thereof with a shrinkable film, thereby preparing a laminate, and then heat stretching the laminate, thereby performing stretching treatment of the resin film while imparting to the resin film the ability to shrink in the direction crossing the stretching direction. A retardation film is formed by using at least one birefringent film and has refractive indexes, n.sub.x and n.sub.y, in two directions parallel to the plate plane and crossing each other at right angles and a refractive index, n.sub.z, in the direction of the thickness of the plate, said refractive indexes n.sub.x, n.sub.y, and n.sub.z satisfying the following equation:0<(n.sub.x -n.sub.z)/(n.sub.x -n.sub.y)<1provided that n.sub.x >n.sub.y.

Abstract: A paper cutter for achieving high speed cutting having a simplified structure since movement of a blade can be controlled by a linear motor. A low level of noise can also be realized since typical mechanical elements for transferring power are eliminated. The movable blade forms less than a fifty degree angle with respect to a blade edge of the stationary blade, in the direction of blade motion, so that locally concentrated wear it minimized. By using a rotary blade as a movable blade, paper can be cut in both directions by reciprocating the movable blade.
