Title: Method for restoring ink jet head
Inventor: SUGAWARA TATSUO
IPC: B41J2/125
Filed: 1991-12-06
Abstract: PURPOSE:To enable high speed printing and to prevent the wasteful consumption of energy and ink by interrupting printing operation only for the diffusion time of an air bubble into ink after the detection of the air bubble in such a case that the air bubble has a size sufficient to diffuse into the ink within a predetermined time to diffuse and eliminate the air bubble. CONSTITUTION:When an air bubble is generated in an ink passage 17, the input voltage to a voltage comparator 50 is zero volt though an ink jet head 4 is driven and, therefore, no pulse is generated in an output terminal 52 and it is judged that the air bubble is present in the ink flow passage 17. That is, when the generation of the air bubble is detected, printing operation is immediately stopped. Next, the head 4 returns to the reference position opposed to a cap device 11 and subsequently stopped for a predetermined waiting time to wait until the air bubble diffuses into the ink to disappear. Since the diffusion time of the air bubble into the ink becomes short as the temp. of the ink or the peripheral temp. becomes higher, the waiting time is changed corresponding to the temp. of the ink or the peripheral temp. During waiting, a display lamp is lighted to inform the waiting of the head to a user.

Filed: 1993-12-22
Abstract: PURPOSE:To surely polarize the whole of a piezoelectric element in the circumferential direction by a method wherein the piezoelectric element shaped to be axially symmetric substantially is heated partially, the heated part is polarized by applying an electric field in the circumferential direction thereto and these heating and voltage impression processings in a sequence are repeated in a plurality of times. CONSTITUTION:A piezoelectric element 1 is provided with electrodes 2 at equal pitches from the surface of the element to the rear through the lateral side thereof and a voltage V is applied to one of the electrodes, while the adjacent one is grounded. A part of this piezoelectric element, a hatched part thereof, is heated in a spot by using a laser beam 4, for instance. Since the piezoelectric element 1 is easy to polarize when it is heated to a temperature near a Curie point, only the hatched part is polarized counterclockwise in the circumrefential direction. By changing sequentially the electrode 2 to which the voltage V is applied and the electrode 2 which is grounded, all spaces between the electrodes can be polarized counterclockwise. The electrodes are replaced with overall electrodes on the upper and lower side, so that it can be used as a piezoelectric element for torsion.
