Title: Preparation of ink jet head
Inventor: OKADA JIYUNICHI
IPC: B41J2/15
Filed: 1982-11-30
Abstract: PURPOSE:To form an ink jet head capable of stably performing injection with high repeated frequency, by welding a substrate to which a initial groove to be used as an ink flow channel is formed to a second substrate while shaping an initial flow channel into a predetermined flow channel by flowing a liquid for dissolving each substrate through said initial flow channel. CONSTITUTION:A groove pattern is formed to a borosilicate glass plate by photoetching to produce a substrate 1 which is then welded to a spacer 7 and a second substrate 2 each comprising the same material as the substrate 1 under heating to form an initial flow channel. A lid 8 is adhered to one end of a common chamber 6 while a pipe 10 is adhered to the other end thereof and a piezoelectric element 3 is adhered to the substrate 2. A fluohydric acid mixed liquid is flowed into thus formed ink jet head through the pipe 10 by a tube pump and discharged from an original nozzle 40. The original nozzle 40 is gradually shaped into the configuration of a nozzle 4 with the elapse of time. At this time, the etching liquid etches both of the substrate 1 and the second substrate 2 to deepen the depth of the flow channel to a large extent.
