Title: Developing method
Inventor: TOMURA SHINYA
IPC: G03G9/08
Filed: 1986-03-26
Abstract: PURPOSE:To stabilize the extent of triboelectric charging and to prevent development fog and the scattering of a toner on the periphery of the edge of a latent image by developing the latent image with a specified positively chargeable nonmagnetic one-component toner. CONSTITUTION:An electrostatic latent image is developed with a positively chargeable nonmagnetic one-component toner contg. a resin having >=50 deg.C glass transition point and 110-160 deg.C softening point, e.g., polystyrene and a colorant such as carbon black. The amount of electric charges produced on the resin by triboelectric charging is +25-150muC/m<2> surface area. When the glass transition point of the resin is <50 deg.C, the shelf stability of the toner is deteriorated. When the softening point of the resin is <110 deg.C, offset is caused. In case of >160 deg.C, the toner is not fixed. When the amount of electric charge produced on the resin by triboelectric charging is <+25muC/m<2>, it is difficult to positively charge the toner. In case of >+150muC/m<2>, it is difficult to form an image. Colloidal silica may be added to the toner so as to improve the flowability and coagulation resistance.

Title: Production of liquid crystal device
Inventor: ODAI HIROAKI
IPC: G02F1/133
Filed: 1988-03-22
Abstract: PURPOSE:To form uniform thin films on which foreign matter is not adhered with good time efficiency and to produce the liquid crystal device at a low cost with high reliability by printing and coating ink on substrates by a spin coating method, then subjecting the coating to a heat treatment on a hot plate thereby forming the insulating protective films. CONSTITUTION:The ruggedness and fine flaws on the surface of the substrates 11a, 11b consisting of a transparent material are removed and the surfaces are cleanly cleaned; thereafter, the thin films of SnO2-added In2O3 are coated thereon by vapor deposition. Plural transparent electrodes 12a, 12b which are insulated from each other are then obtd. by etching the ITO films to desired patterns. The ink prepd. by dissolving a material essentially consisting of silicon dioxide in a solvent, etc., is selectively printed and transferred to a prescribed shape by the spin coating method to form the thin films. The transparent substrates formed with the thin films on the surfaces are transferred onto the hot plate right after the end of the printing and the thin films are baked. Although the hot plates are already heated to 300 deg.C, the failure of the substrates does not arise even if the ordinary-temp. transparent substrates are placed on the hot plate. The deposition of the foreign matter onto the insulating films is thereby obviated and the insulating films 13a, 13b having the stable quality are formed with the good time efficiency.
