Abstract: PURPOSE:To correct the shift of a tomographic image, by adding an offset amount to information related to the position and the direction of the display scanning line of each vibrator when the shift of the tomographic image is generated by the attaching errors of a plurality of ultrasonic vibrators in a single probe.

Synchronizing signals delayed by memory 3 are inputted to circuit 4 also and have the phase compared with the phase of snychronizing signals which are not delayed, and the comparison result is fed back to clock generator 5. Here, a time when periodicity of synchronizing signals exists is selected as the delay time. Now, in case of clock repeated frequency f>ideal repeated frequency f 0 , delay time T<set delay time T 0  is true, and then, circuit 4 detects advance of synchronizing signals which passed through memory 3 and controls so that the clock repeated frequency may be lower. Otherwise, in case of f<f 0 , T>T 0  is ture, and then, circuit 4 controls so that the clock repeated frequency may be higher.

Title: Ink jet head
Inventor: OGAKI TAKASHI
IPC: B41J2/135
Filed: 1986-06-20
Abstract: PURPOSE:To strengthen the joint between a head body and a nozzle plate, by penetrating an adhesive through a dovetail groove formed in the nozzle plate then jointing the nozzle plate and the ink jet head body. CONSTITUTION:A gap pattern 5b thinner than a pattern 5a for a throgh-hole is patterned simultaneously with an etching pattern, then said patterns 5a, 5b are etched simultaneously to form a nozzle hole 3 and a dovetail grove 6. The dovetail groove is formed toward the center so that an adhesive spreads easily through capillary action at the circumferential section. In order to form a dovetail etching hole, the original pattern must be thin. Since a thin pattern causes abrupt droppage of etching rate, thus remaining a small hole, the liquid temperature is controlled properly. Consequently, the adhesive permeats through the dovetail groove 6 so as to joint a nozzle plate 2 and a head body 1 firmly.
