Title: On-demand type ink jet head
Inventor: ISAYAMA TAKUO
IPC: B41J2/045
Filed: 1984-11-16
Abstract: PURPOSE:To reduce the area of a flexible wall of an ink pressurizing liquid chamber and facilitate integration and reduction in size of the title head, by a construction wherein the distance from an engaging point of a vibrating plate and an elastic body to a point of support of the vibrating plate by a support is set to be longer than the distance from an engaging point of the vibrating plate and a vibrator to the point of support. CONSTITUTION:When a driving pulse is impressed on an electrostrictive vibrator 19 to contract the vibrator 19 in vertical direction, the vibrating plate 18 is displaced downward with the support 17 as a fulcrum. The downward displacement of the plate 18 displaces the vibrating plate 15 downward through a vibrating rod 16, whereby the volume of the ink pressurizing liquid chamber 13 is reduced. As a result, the pressure inside the chamber 13 is raised, and an ink droplet is jetted through a nozzle 11. The vibrating plate 15 is displaced by an amount obtained by amplifying the contraction of the vibrator 19 at a ratio of the distance between the support point of the support 17 and the rod 16 to the distance between the support point to the vibrator 19, and accordingly, the strain of the vibrator 19 is amplified.

IPC: H03K19/00
Filed: 1985-10-29
Abstract: PURPOSE:To easily identify a small set group generating a shift pass fault by providing a logical device with a shift control part for a shift pass, an indication part for dividing the shift pass on the way and indicating a by-pass and a switching part. CONSTITUTION:Switching indication signals 10-13 are turned to logical '0' by the shift pass switching indicating part 2 to execute shift in/out by a shift control part 1. When a shift pass fault is detected, only the signal 10 is set up to '0' and other signals are set up to '1' by the indication part 2 to execute shift in/out by the control part 1. If a shift pass fault is detected at that time, the existence of a fault in the shift pass of a multi-chip package 4-1 is decided. Since the faults of the multi-chip packages 4-1-4-4 can be detected by successively setting the signals 10-13 to '0' or '1' similarly, a fault of an individual FF having a shifter constituting the package or that of a small set group can be distinguished from other FFs or small set groups and can be easily detected.
