Filed: 1985-03-15
Abstract: PURPOSE:To provide a thermal transfer paper having favorable adhesion of an ink layer to a film and free of abnormal transfer, by using a high molecular weight polyamide resin based on a dimer acid as a binder for an ink layer. CONSTITUTION:The binder is a high molecular weight polyamide resin based on a dimer acid, preferably having a softening point of 100-200 deg.C.

Title: Method and device for controlling ink discharge in ink jet printer
Inventor: SUZUKI SHOGO
IPC: B41J2/045
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To make the generation of irregularities hardly occur in an image to be formed in a medium to which an image is to be recorded under the effect of a crosstalk phenomenon at the time of ink discharge. SOLUTION: In this ink jet printer, an inductor 64 is introduced in series in an energization route 83. When a drive voltage rises or falls, an undershoot or an overshoot which becomes significant by the inductor 64 in proportion to the number of times of driving a piezoelectric element, is generated in a drive current. Consequently, under this effect of the generation such a phenomenon, the drive voltage is increased in proportion to the number of times of driving the piezoelectric element. Therefore, following the increase in the number of times of driving the piezoelectric element, the drive voltage in the piezoelectric element is higher, resulting in the generation of a stronger pressure to be brought to bear upon an ink. Thus the deterioration of a discharge rate of the ink under the effect of a crosstalk phenomenon does not occur, and it turn, the generation of irregularities in the image formed on a recording sheet hardly occurs as a favorable effect.

Title: Ultrasonic liquid atomizing circuit
Inventor: TAKAHASHI MINORU
IPC: F24F6/12
Filed: 1981-04-06
Abstract: PURPOSE:To facilitate an easy control and maintenance of an atomizing circuit, by oscillating a piezoelectric oscillator itself with a frequency proper to an appropriate piezoelectric oscillator for atomization of liquid and supplying a sufficient energy for atomization of liquid to the oscillator only through an oscillating circuit. CONSTITUTION:The resonance frequency fO produced through the parallel resonance circuits C1 and L1 is designed at a level lower than the frequency fVM (frequency with which the quantity of fog is maximum). In case an oscillator TD is identical with an inductor, it functions as a Colpitts oscillating circuit. And the constants of C1, L1 and C2 are selected so that they have oscillations with the frequency fVM. Then a variable resistor R2 and a diode D1 are connected in series between the base of a transistor Q1 and the earth. Thus a part of the oscillated high frequency current is rectified to receive a positive feedback and to be turned into a bias current. Accordingly a bias resistance R1 can be increased with the power consumption decreased for the resistance R1.
