Title: Piezo-electric element drive circuit in ink jet system printer
Inventor: WATANABE KAZUO
IPC: B41J2/12
Filed: 1980-12-19
Abstract: PURPOSE:To enable to perform a temperature compensation of an ink jet amount and  jet speed in reaction to an ambient temperature change without the need for complicated regulation of a circuit, by mounting a heat sensitive resistance element at a  path where charging and discharging currents flow to a piezo-electric element. CONSTITUTION:A heat sensitive resistance element Th of a negative property is mounted on a discharge path of a piezo-electric element Pi. Before a drive pulse signal Vs  rises, transistors Q3 and Q1 are in an OFF state and a Q2 is in an ON state, and a voltage Vp applied to the opposite ends of the piezo-electric element Pi is brought to naught. When the pulse signal Vs rises, the transistors Q3 and Q1 are brought to ON in  sequence, and simultaneously, the Q2 to OFF. Charge is accumulated in the piezo-electric element Pi and the voltage Vp applied to the opposite ends is equalized with a  potential difference at a+ and a- side. Then, if the pulse signal Vs falls, the transistor  Q3 is broughnt to OFF again, and the voltage Vp applied to the opposite ends of the  piezo-electric element Pi changes. Since, however, a resistance element Th has a negative property, a width of a drive pulse Dp applied to the piezo-electric element Pi changes so as to perform a compensation in reaction to an ambient temperature.

Abstract: PURPOSE:To obtain raw material powder for a sintered compact of the excellent critical current density by mixing calcined mixed powder of Bi2O3, SrCO3 and CaCO3 and CuO in a specific proportion with anhydrous CaBr2 powder in the air, sintering the resultant mixture powder in a vacuum and then pulverizing the sintered powder. CONSTITUTION:The above-mentioned Bi-based superconducting oxide powder is obtained by blending, mixing and calcining respective powders of Bi2O3, SrCO3, CaCO3 and CuO at 2:2:1:3 molar ratio of 1/2Bi2O3:SrCO3:CaCO3:CuO. The resultant calcined substance is then pulverized to afford a low-Tc phase Bi-based oxide calcined powder composed of Bi2Sr2Ca1Cu3Ox. When anhydrous CaBr2 powder is then mixed with the aforementioned calcined powder, the formed mixture absorbs moisture in the air to be converted into CaBr2.6H2O, which is simultaneously adsorbed on the periphery of the aforementioned calcined powder. The obtained powder is then sintered in a vacuum and the above- mentioned calcined powder is reacted with the CaBr2 and converted into a high Tc phase Bi-based oxide composed of Bi2Sr2Ca2Cu3Ox.
