Title: Method of driving ink jet recorder
Inventor: AOKI ATSUSHI
IPC: B41J2/21
Filed: 1986-10-09
Abstract: PURPOSE:To obtain high discharge stability, frequency response, gradation and recording precision by applying auxiliary pulses after application of a discharge pulse to weaken the reflective wave of a pressure wave generated by the discharge pulse, and at the same time, changing the auxiliary pulse in accordance with the size of the discharge pulse. CONSTITUTION:A pulse shape P1 which increases the volume of an ink chamber 3 rapidly is initially applied to a drive signal shape, and later a pulse shape P2 which reduces the volume of the ink chamber rapidly is applied. After application of this positive pulse shape P2 and subsequent discharge of the main droplets of ink droplets, a negative pulse shape P1 is applied. Then following the lapse of 2l/c, a negative pressure wave p1 generated by the pulse P1 travels back and forth once through a nozzle, reversing the phase to become a positive pressure wave p1'. This positive pressure wave returns to the tip of the nozzle, and after the lapse of 4l/c following the application of the positive pulse shape P2, a positive pressure wave p2 generated by the shape P2 shuttles through the nozzle. Therefore, a negative pulse shape P3 is again applied to generate a negative pressure wave p2 and consequently to offset the positive pressure wave p2'. Thus the unstable discharge ink droplets can be eliminated.

Abstract: PURPOSE:To restrict vibration of a meniscus by eliminating a pressure wave, which returns to the neighborhood of a discharge port after the lapse of a prearranged time following the application of an electric signal for discharge of ink droplets, by application of an electric signal which enables the volume of a discharge energy action chamber at the time of return of the pressure wave to be increased. CONSTITUTION:A pulse shape P2 which increases the volume of an ink chamber 3 rapidly is initially applied to a drive signal shape, and then a pulse shape P2 which reduces the volume of the ink chamber rapidly is applied. Next, a negative pressure wave p1 passes back and forth once through a nozzle after the lapse of 2l/c following the application of the pulse shape P1. Consequently, the phase is reversed to change the negative pressure wave to a poisitive pressure wave p1', which, in turn, returns to the tip of a nozzle. Timed to this, a negative pulse shape P2 is applied to give a negative pressure wave p3. As a result, the positive pressure wave p1' apparently disappears, holding down the vibration of a meniscus. After this, after the lapse of 4l/c following the application of a positive pulse wave P2, a positive pressure wave p2 makes a return trip twice through the nozzle. Therefore, is a negative pulse shape P4 is applied to generate a negative pressure wave p4, a pressure wave p2' goes out of sight, thus eliminating the unstable discharge of ink droplets.

Abstract: PURPOSE:To prevent the intrusion of a solid particle between a magnetic head and a magnetic recording medium and to reduce the lowering in probability in reproduction impossibility by eliminating the solid particle arriving at the vicinity of the magnetic head. CONSTITUTION:Air flow arriving at the vicinity of the magnetic head by the rotation of a magnetic disk is divided to the flow 101 flowing along a side surface 42 and the flow 103 flowing along an outer peripheral side after deflected by the side surface 41 at a turning point between the flow-in side surface 41 and the inner peripheral side surface 42, and the greater part of the flow flows to the outer surface at the side surface 41. Then, after passing through a cross point between the side surface 41 and the outer peripheral side surface 103, the flow flows in the direction of the rotation of the magnetic disk. Thus, the solid particle in the air flow arriving at a magnetic head flow-in side is eliminated in the direction of the outer periphery 207 along the flow flowing in the direction of 207 in the vicinity of the side surface 41 without intruding between the magnetic head and the magnetic disk. At this time, since the side surface 41 faces only the outer periphery direction 207, and a dust particle in the direction of the inner periphery is not eliminated, the dust particle arriving at the vicinity of the magnetic head once is eliminated from the vicinity of the magnetic head.
