Granted: 2000-12-01
Abstract: PURPOSE: A method for manufacturing a heater for a cathode ray tube is provided to improve adhesion power and to prevent defect of works by spraying insulator with deposition. CONSTITUTION: A heater(11) is inserted into a sleeve(12) on which a cap(13), doped with a thermal electron emitting material, is covered. A tungsten wire is coiled with a proper size, and then a carbon sprayed for a good processing is removed within a hydrogen(H2) mood, and then a contaminated impurities when coiling is removed at about 1,450 celsius degree. An insulator(16) is sprayed on the heater(11) in order to prevent short between the coiled heater(11). An insulator spraying process is executed with deposition as an important process. An active metal of solid solution point like as Y, Zr, Nd, Ti, Hf is formed as an oxide(Y2O3, ZrO2, Nd2O2, TiO2, HfO3) layer. A surface of the heater(11) is made a blackening treatment with tungsten powder by dipping method and is washed and is completed to improve thermal radiation efficiency of the heater(11) and to expand the life of the heater(11).

Title: Liquid crystal electro optical element and liquid crystal display
Inventor: TANAKA TAKAAKI
IPC: G09G3/36
Filed: 1993-07-16
Granted: 2001-12-28
Abstract: PURPOSE: A liquid crystal electro optical element and a liquid crystal display are provided to introduce an electro optical element which uses a chiral nematic liquid crystal with bistable states and realizes display characteristics of high contrast ratio and high transmittance. CONSTITUTION: Electrodes(4) and alignment layers(2) are installed in each inside part of a pair of substrates(5) facing with each other and arranged between a pair of polarizers(7). A chiral nematic liquid crystal medium(21) is inserted. The chiral nematic liquid crystal medium(21) adjusts a helical pitch Po, to make a twist angle in an initial state before voltage supply for an angle 'phi r' formed by rubbing directions(19,20) for each alignment layer(2) becomes around 'phi r'. In the initial state, angles formed between director vector of liquid crystals contacting with each alignment layer(2) and a substrate surface are inversely coded. As a relax state after a pulse voltage is supplied in the initial state, a state is converted to two metastable states in which twist angles of liquid crystals are around 'phi r'+180 deg. and around 'phi r'-180 deg. According to a multiplication(delta n) between the thickness(d) of the chiral nematic liquid crystal medium(21) and a double refractive index of liquid crystals and 'phi r', each angle of P and A between polarizing axes of each polarizer(7) and one rubbing direction is set to a contrast ratio of 2 or higher between the metastable states.
