Title: Ink jet head
Inventor: NAKA TAKAHIRO
IPC: B41J2/055
Filed: 1990-03-19
Abstract: PURPOSE:To make it easy to discharge bubbles by arranging an ink chamber annularly so as to surround the pressure chambers, and besides, positioning a supply port for supplying ink to the ink chamber at a place above the ink chamber. CONSTITUTION:An ink chamber 5 which supplies ink to each of pressure chambers 2 is arranged annularly on the same plane as the pressure chambers so as to surround all the pressure chambers, communicating with each of the pressure chambers from the inner circumference thereof through a throttle part 6. Ink from an ink tank enters the ink chamber 5 through a supply pipe 9 in the vertical direction with respect to a board 1. The ink then spreads in the ink chamber 5 and proceeds to each of the pressure chambers 2, a flow passage 3 and a nozzle 7. On the other hand, when the board 1 is installed in a recorder to suck and charge the ink, streams of the ink from both sides meet at the lower central part of the ink chamber 5. Then, bubbles produced at the confluence go up due to buoyancy to flow into the pressure chambers 2 and are discharge to the outside through the nozzle 7.

Abstract: PURPOSE:To obtain a thermal writing type liquid crystal information recording and displaying device enabled to display with a high contract ratio or write records at a high speed by providing a means for switching a frequency and applying the switched frequency to a smectic liquid crystal layer and a means for partially selecting and heating the liquid crystal layer. CONSTITUTION:The frequency f1 of voltage applied from a power supply 85 to a liquid crystal substance 84 is selected lower than the critical frequency fc(Tb) allowing the liquid crystal substance 84 to invert the sign of dielectric constant anisotropy at the ambient temperature Tb of operation which is lower than the temperature TSN generating smectic phase transition and the frequency f2 of voltage applied by a power supply 86 is selcted higher than the critical frequency fc(TSN) allowing the liquid crystal substance 84 to invert the sign of the dielectric constant anisotropy at a temperature TSN. The liquid crystal substance at a part irradiated by a writing laser light beam 2 and selectively heated is increased at its temperature and transferred to the nematic phase, but if the voltage of the frequency f2 is applied at the drop of the temperature, the liquid crystal substance shows extremely strong light scattering as compared to the case of no application of voltage. Thus, a large value such as 20 is provided to the contrast ratio of display by adding a strong light scattering effect based upon a dynamic scattering phenomenon to a writing picture element.
