  • Patent number: 6177153
    Abstract: A film of the present invention is an oriented film having a light-scattering property varying with an incident angle and is useful e.g. as a viewing angle improvement film effective for improving the picture quality of a liquid crystal display device, especially for expanding the viewing angle. This oriented film is composed of a thermoplastic polymer and contains a number of micro voids participating in the above scattering property in the film. It can be produced by uniaxially drawing a film composed of a thermoplastic polymer under temperature and draw-ratio conditions to form grooves on the surface of the film perpendicular to the drawing direction.

  • Patent number: 4128702
    Abstract: A half cell using a halide salt of N,N'-bis(substituted phenyl)-4,4'-dipyridyl as the cathode depolarizer has higher discharge voltage than those conventional cells using other organic compounds. Moreover, the primary cells or the secondary batteries therefrom have higher energy density and flatter discharge curves and thus they are very useful as compact and light cells or batteries. 2,4-Dinitrophenyl and 4-cyanophenyl are preferable as the substituted phenyl group.
