Title: Method for controlling printing of ink-jet printer
Inventor: IWAMI HIDEAKI
IPC: B41J2/055
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling printing which increases a quantity of drops of ink to be discharged. SOLUTION: An ink pressure chamber for storing ink is constituted of piezoelectric elements 2, 4. A voltage is impressed separately to the piezoelectric elements 2, 4, thereby deforming the piezoelectric elements 2, 4 to expand, shrink the ink pressure chamber. The ink is consequently sucked and discharged from nozzles thereby performing printing in an ink-jet printer according to the printing control method. In the method, the ink suction operation of deforming the piezoelectric elements 2, 4 to expand the ink pressure chamber is started immediately after a driving timing of an adjacent nozzle. Accordingly, a quantity of the ink sucked to the ink pressure chamber is increased, so that a quantity of drops of the ink discharged in the discharge operation is increased.

Abstract: PURPOSE:To control the intensity of a current which flows between a first normal conductor and a second normal conductor so as to obtain a transistor of small power consumption by a method wherein a potential difference is given between the first and the second normal conductor to change the potential of a superconductor. CONSTITUTION:Provided that an energy gap of a superconductor 102 is DELTA2, the superconductor 102 is provided with a band changed with electrons at a level lower than mu2-DELTA2 and another band nearly vacant at a level higher than mu2+DELTA2. A fixed potential V1 is so set as to satisfy an inequality, mu1-mu3<2DELTA2. And, when mu2 is made to vary by changing V2 and both inequalities, mu2-DELTA2<mu3 and mu2+DELTA2>mu1, are satisfied, a band, whose level is equal to a Fermi level mu1 of a normal conductor 101 and a Fermi level mu3 of a normal conductor 103, does not subsist in the superconductor 102, so that electrons can not tunnel and a current I flowing between the normal conductors 101 and 103 grows to be nearly zero. When mu3<mu2+DELTA2<mu1, electrons are made to flow from the normal conductor 101 to the superconductor 102 and furthermore from the superconductor 102 to the normal conductor 103, therefore a current flows.
