Title: Manufacture of orifice plate
Inventor: OHASHI YUMIKO
IPC: B41J2/135
Filed: 1991-05-15
Abstract: PURPOSE:To improve quality by forming a modified layer at a position in specified depth of a substrate, forming a mask pattern in the modified layer and manufacturing an original disk and forming an electroforming film by the original disk in the title plate of the discharging section of an ink-jet printer. CONSTITUTION:A conductive substrate 20 such as an Si wafer is heated in the steam atmosphere of steam water, and a specified depth section from the surface of the substrate 20 is modified to form an SiO2 layer 21. A photo-resist pattern 22 is formed onto the substrate 20, to which the SiO2 layer 21 is formed. The SiO2 layer 21 exposed is etched until the Si of the substrate 20 is exposed. An internal gas in a device is replaced with O2, and the photo-resist pattern 22 is removed through ashing and a non-conductive SiO2 pattern 21a is shaped. The upper section of the substrate 20 is coated with a releasing film 23, and the electroforming film 24 of nickel is electro-deposited. The electroforming film 24 is peeled from the substrate 20, thus obtaining an orifice plate 11.

Title: Device for consecutive image picking-up for magnetic recording and reproducing device
Inventor: SEKIYA MASATAKA
IPC: G11B27/038
Filed: 1986-05-16
Abstract: PURPOSE:To make the display gradually shift from a scene A to a scene B in a reproduced picture by re-recording the ending part of the already recorded recording of the scene A with the video signals of the scene B on every other tracks, and forming the tracks of the video signals of the scene B continuously following the ending of the recording area of the scene A. CONSTITUTION:When a picture recording command is issued, in case of consecutive image picking-up, every other ones of the already-formed tracks on a magnetic tape 1 are re-recorded by either video head 2 or 3. Then, a counter 10 counts up output pulses from a NAND gate 12, and when the counting reaches a prescribed value, the video heads 2 and 3 writes video signals consecutively on the magnetic tape 1. Thus, immediately after the command of a recording command, new video signals are intermitently recorded on every other tracks, and this recording is repeated for a duration of several fields. Thereafter, the recording turns to be continuous. As a result, a visual effect of gradual shifting of scenes can be obtained.
