MANUFACTURE OF COMPOSITE PIEZOELECTRIC MATERIAL

摘要

PURPOSE:To alleviate the waste of blank materials and rationalize the manufacturing process by a method wherein a composite piezoelectric film is produced by printing which makes electrostatic latent images visible by using charged particles containing piezoelectric high molecules and a piezoelectric inorganic material. CONSTITUTION:A photosensor 1 is scanned with an electrifier 3 and thus evenly electrified by corona discharge. Electrostatic latent images 5 are formed by exposing rectangular patterns on the photosensor 1 through a lens 4. Charged particles are deposited on the latent images by magnetic brush development, and the latent images are made visible. The developer made of developer charged particles is transcribed on a Mylar film 11. Said developer composed of charged particles being transcribed is fixed by means of heat rollers 12 and 13.
