Title: Ink jet head and manufacture thereof
Inventor: TAKAO SHIGEYUKI
IPC: B41J2/055
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To obtain a small ink jet head in which half toning can be controlled by applying an actuator tightly, while aligning, to the face of a pressure chamber plate coated with electrodeposition resin thereby curing the electrodeposition resin. SOLUTION: A photosensitive glass l0 electrodeposited with acryl resin is applied, while being aligned, onto an MgO substrate 14 where an actuator part is formed by deposition, or the like, while being micromachined by photolithography, or the like. Central part of the actuator is set in the center of a trench in the photosensitive glass 10 which is then pressed from above so that the photosensitive glass 10 adhere to the substrate 14 while exhibiting some degree of liquidtightness. Subsequently, the adhesive electrodeposition resin is cured completely while raising the temperature of the photosensitive glass 10 and the MgO substrate 14 after finishing water repellent treatment with Cr.  Since the adhesive does not project into the actuator part in a pressure chamber at the time of adhesion, ink ejection can be controlled accurately depending on the pulse voltage and control range of halftoning is widened.

Abstract: PROBLEM TO BE SOLVED: To make a device simple and inexpensive by reducing the number of parts. SOLUTION: By a detection means 54, a voltage signal from a perforation sensor 13 is periodically sampled in the midst of a film feeding action. That means, the voltage signal is fetched at several (msec) intervals through an A/D conversion means 53. By using data stored in a this-time storage part 41, a last-time storage part 42 and a time-before-last storage part 43, it is detected whether the voltage signal of the sensor 13 tends to increase or decrease and the detected result thereof is stored in a change state storage part 45. Besides, it is detected whether inversion exists or not between the increasing tendency and the decreasing tendency. When the inversion is detected by the detection means 54, the number of inverting time is stored in a storage part for storing the number of inverting time 44 by a counter 55.  When the number of stored time becomes 16, it is decided that one frame of a film 21 is fed.
