Title: Liquid-crystal color display
Inventor: KAMAMORI HITOSHI
IPC: G02F1/137
Filed: 1978-07-13
Abstract: PURPOSE: To enhance the legibility of a dynamic-dispersion-effect type liquid-crystal display and to make the display fashonable under any condition by adding two- color fluorescent pigments into a nematic-liquid-crystal composition having negative inductive anisotropy.  
     CONSTITUTION: An n-type nematic-liquid component 4, in which two-color fluorescent pigments 5 are added, is inserted between a transparent substrate 1-1, and is arranged vertically. Under this condition, since the pigmens 5 are not excited and do not emit a fluorescent light, a reflected light 9, which is the outcome of the incident light 7 reflected from a reflecting coating layer 3, that is, the portion where no voltage is applied, becomes discolored. When a voltage is applied across transparent electrodes 2-2, and the composition 4 is changed into scattered condition, the pigments 5 become approximately horizontally arranged, are excited by the light 7, and emit fluorescent light. Therefore, a reflected light 8 from the portion where the voltage is applied displays scattered fluorescent lights, thereby contrast is enhanced.

Abstract: PURPOSE:To extend the service life of the title electrode for spot welding by ionizing metal with low electric resistance and metal which hardly reacts to Zn at the high temperature in a vacuum chamber and coating these metallic ions in order on the electrode head. CONSTITUTION:The metal 13 such as Ag and Cu with low electric resistance and the metal 14 such as Co and Mo which hardly reacts to the Zn at the high temperature are arranged in the vacuum chamber 11 and the metallic ions 13a and 14a are released by energies of respective arc power sources 12a and 12b.
