IPC: C23C18/12
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To form a Pb-contg. metal oxide thin film pattern having rather large film thickness by a solgel method. SOLUTION: Plural layers of coating films are formed by applying a pattern- forming compsn. for a Pb-contg. metal oxide thin film on a substrate. Before the upper coating film is formed on the lower coating film, the lower coating film is heated to partially polymerize a hydrolytic metal compd. in the pattern- forming compsn. for the Pb-contg. metal oxide thin film. Then the layers are exposed for an image forming, the unexposed part is removed and the pattern is heat-treated. By this method, dissolution of the lower coating film in the pattern-forming compsn. for the Pb-contg. metal oxide thin film applied to form the upper layer coating film can be prevented. Thereby, the pattern- forming compsn. for the Pb-contg. metal oxide thin film can be applied as an overcoat to obtain a thick coating film.

Filed: 1981-10-30
Abstract: PURPOSE:To obtain easy-to-see display while reducing a flickering of a display screen by replacing a synchronizing signal in a received signal by a regenerated synchronizing signal regenerated on the basis of the synchronizing signal, and displaying character and graph information by use of the replacing signal. CONSTITUTION:To receive a character broadcast, a control output for the character broadcast is applied to terminals B5 and B8, and while switches 9 and 10 are changed over to obtain (b)-(c) connections, a switch 11 is changed over to obtain (a)-(c) and (b)-(c) connections. In this state, a broadcast signal with an weak electric field is received, and the output of a tuner VIF video detecting circuit 12 is transmitted, as it is, to a terminal B4. Consequently, character and graph information displayed on a cathode-ray tube has a flicker, so the synchronizing signal in the video signal outputted to the terminal B4 is replaced by another synchronizing signal to obtain a signal synchronizing with the synchronizing signals of character broadcasting circuit 14 and 15. Consequently, a relative flicker which is large horizontally is reduced as much as possible.
