    摘要： An apparatus for liquid-jet recording comprises an electro-thermal transducer and discharge openings for jetting a liquid by thermal action of the electrothermal transducer. The electro-thermal transducer is connected directly to a lower potential side of a power source and is connected to a higher potential side of the power source through a switch element. Thermal action of the thermal transducer occurs upon the application of a positive voltage of a high potential from the power source through the switch element.

    摘要： An electron emission apparatus can effectively suppress the adverse effect of electric discharges that can take place between the oppositely disposed electrodes of the apparatus to which a high voltage is applied by dividing the electrode adapted to have a higher electric potential into segments in order to reduce the electrostatic capacitance between the electrodes. In the case of an electron emission apparatus comprising electron-emitting devices, said plurality of electron-emitting devices are disposed such that the direction along which those that can be driven simultaneously are arranged is not parallel with the direction along which the electrode is divided into the electrode segments in order to reduce the variable range of the electric current that can flow in the segments.

    摘要： An ink jet recording method includes the steps of providing an ink jet recording head having a plurality of discharge openings for discharging ink, a plurality of liquid passageways for holding ink and a plurality of heat generating members. Each of the heat generating members corresponds to a liquid passageway and each heat generating member has a pair of electrodes for driving the heat generating member individually and the electrodes and corresponding heat generating member form a U-shaped wiring portion. The recording head may be manufactured using a cutting process. A voltage is applied to selected pairs of electrodes for driving selected heat generating members individually for providing thermal energy to the ink in the liquid passageway for abruptly forming a bubble and discharging ink from the discharge opening and recording on a recording medium.
