Title: Ink jet recording method, ink jet recording head and ink jet recording
Inventor: HOSAKA TAKESHI
IPC: B41J2/01
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To simplify the driving method by modulating the driving frequency to jet a next ink at the timing when the liquid level of ink is projecting above the surface of ink jet port. SOLUTION: When a pulse is applied under steady state (a) prior to jetting, jetting of main droplet is started to bring about a state (b) prior to liquid separation and a main droplet is jetted through a jet port 8 to bring about a state (c) immediately preceding liquid separation which is followed by a state (d) where the liquid level receded back to the jet port and a state (e) where the liquid level bulges above the jet port before returning back to the steady state (f). The driving frequency is modulated to jet a next ink at the timing when the liquid level of ink is projecting above the surface of ink jet port. Consequently, a third convenient driving method for head other than temperature regulation and pulse width modulation, can be attained.

IPC: G11B5/56
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To surely cancel erroneous adjustment of plural magnetic heads and automatically adjust them even when they are closely arranged by deciding the adjusting order of the counter gap of the magnetic head from the downstream side. SOLUTION: This magnetic head device adjusts counter gaps between plural magnetic heads 17-22 simultaneously being in contact with a magnetic medium 12. The adjusting order table of the magnetic heads 81 preferentially indicates the gap adjustment to all six magnetic heads 17-22 when the abnormality of gaps is detected. For example, when the gap abnormality occurs in a magnetic head 19 on the front surface of a coupon information write part B, three magnetic heads of the head 19, a magnetic head 20 on the rear side on the downstream side and a magnetic head 21 on the front surface of a coupon information checking part B on the more downstream side 19-20 are simultaneously brought in contact with mutually. Consequently, the gap adjustment of the magnetic heads 20, 21 on the downstream side of the magnetic head 19 are preferentially adjusted.

Abstract: PURPOSE:To manage the validity automatically even for a guide content with the validity by providing a clock means counting a current date and an auxiliary memory storing a sound element data with validity with a date data designating a period for guide broadcast added thereto. CONSTITUTION:A clock means 23 provided on a guide broadcast equipment 10 always counts clocks to count the current date and the date data representing a period to be guided is added to a sound element data such as advertisement data and the resulting data is written in an auxiliary memory 22.
