Title: Plasma chemical vapor deposition device
Inventor: MATSUO MUTSUMI
IPC: H01L31/0248
Filed: 1983-08-09
Abstract: PURPOSE:To prevent a contamination to a substrate from an electrode by sputtering, and to form a clean thin-film by coating the electrode with an insulator with a mechanism ejecting a reaction gas. CONSTITUTION:The whole of both upper and lower electrodes is coated with silica glass 11. When the thickness of silica glass 11 is too thin, contamination is prevented incompletely, and life is shortened. When the thickness is too thick, on the other hand, the loss of a high-frequency power supply is large, and effective power applied to a reaction gas lowers. When silica glass is used, thickness of several mm. is proper. The coating of the lower anode electrode aims at the prevention of the contamination of electrode main constituent elements by the heating of a substrate, and the coating of the upper cathode electrode aims at the prevention of contamination to the sputtering of the electrode main constituents. Introducing ports and exhaust nozzles 10' for the reaction gas are often formed to silica glass coating the upper cathode electrode in order to obviate the contamination of the electrodes and ensure the uniformity and stability of a plasma state.

Title: Ink jet head
Inventor: MUNEHIRO HIDEHIKO
IPC: B41J2/055
Filed: 1984-07-13
Abstract: PURPOSE:To minimize variation of pressure in an ink reservoir and a nozzle, by arranging piezo-oscillators in such a way that directions of polarization may be opposite to each other when adjacent piezo-oscillators are driven.

Abstract: PURPOSE:To decide the used/unused state of a film by observing a display window, to read out information at the time of reloading the film and to prevent the film from being reused by providing a cartridge main body with a display window and a display changing means for displaying a used state. CONSTITUTION:A display plate 25 is finally pushed out into the display window 15 by the rotation of a spool 6 and a 'cross' mark is displayed on the display window 15. When the leading end of a magnetic layer is opposed to a recording/ reproducing head 60 and a perforation counter counts up '10', a microcomputer drives the head 60 and then displays the number '24' of residual frames on a liquid crystal display part 45.

Then, the microcomputer stops the spindle 39 to set up the 1st frame of the film 5 to an exposing aperture 37a. When a release button 43 is depressed, the microcomputer forward rotates a motor to wind up the film 5. When the perforation counter counts up '8', the microcomputer stops the motor to stop the winding of the film 5. Thus, the 1st frame is carried and the 2nd frame is set up to the aperture 37a.
