摘要： A method of manufacturing an optical compensator sheet comprising the steps of providing a sheet of ionomer, which ionomer is bridged with sodium or magnesium ions, stretching said sheet of ionomer along one direction in the plane of sheet, so as to generate uni-axial optical anisotropy of predetermined amount having an optical axis along the stretched direction, sandwiching said stretched sheet of ionomer between a pair of substrates, putting said sandwiched sheet in an evacuatable heat-resisting bag, evacuating and sealing said bag, loading said bag in an autoclave furnace and applying heat and pressure to said sheet in said autoclave furnace at a temperature not less than the melting point of the sheet. The stretched sheet has a positive optical anisotropy along the stretched direction. The sheet after heat and pressure treatment has a negative optical anisotropy along the normal to the sheet.

摘要： Ionomer resin sheet is stretched in one direction in the plane of sheet to give uniaxial anisotropy, and then heated above the melting point under pressure to cause relaxation of the anisotropy. After cooling, a sheet of biaxial anisotropy is obtained. The degree of anisotropy depends on the initial stretching, heating temperature, heating time and pressure.

摘要： The present invention provides a cathodoluminescent display which uses guided electrons and a control process for such display. The display is in matrix form, an image or picture point or dot being formed at each row-column intersection. Opposite the columns, outside the image dots, a source continuously emits electrons. As a function of the signal which it receives, a column electrode guides up to the selected row the electrons emitted opposite it, or drives them back to the source. The guidance column electrodes are covered by an electrically insulating layer, the guidance of the electrons taking place in a vacuum in the immediate vicinity of the insulant perpendicular to the guidance electrodes.
