    • A print head has a reduced power size or increased print speed that can be operated at a lower voltage or higher speed and can maintain high-quality output printing free from thinned portions. During intervals between printing operations while a print paper is being fed, pulses are applied to all print electrodes to maintain a uniform potential difference between each of the print electrodes and a counter electrode so that an electric charge is supplied to the ink meniscus. Consequently, a sufficient Coulomb force to permit ink droplets to be ejected is obtained. Therefore, during printing operations, the supplied energy can be reduced and electric charge on the ink surface can be retained. Hence, ink droplets can be ejected stably without nonuniformities.
    • 打印头具有减小的功率尺寸或增加的打印速度,其可以在较低的电压或更高的速度下操作并且可以保持没有变薄部分的高质量的输出打印。 在打印纸被供给期间的打印操作之间的间隔期间,脉冲被施加到所有打印电极,以保持每个打印电极和对电极之间的均匀电势差,从而向墨水弯月面供应电荷。 因此,获得足够的库仑力以允许墨滴喷射。 因此,在打印操作期间,可以减少所提供的能量并且可以保持墨表面上的电荷。 因此,墨滴可以稳定地喷射而不均匀。

    • In an electrostatic acceleration type ink jet recording apparatus, when a voltage is preliminarily applied to ink to adjust the width of ink raises, a dedicated drive circuit has been necessary or dedicated electrodes have been necessary for forming the ink raises. According to a recording apparatus of the present invention, machining such as chamfering or steps is provided to a support body having a slit-like opening portion or, alternatively, a surface treatment such as coating an oil repellent solvent to a portion to be machined. Due to such a constitution, the width of the ink raises in the lateral direction of the opening portions can be made constant without using a method such as an electric driving so that a stable printing of dots is ensured. Further, by increasing the ink raise width in the vicinity of a central portion of the opening portion than at end portions of the opening portion, it becomes possible to prevent the diameter of dots to be printed from becoming non-uniform in the longitudinal direction of the opening portion.
    • 在静电加速型喷墨记录装置中,当预先将电压施加到墨水以调节墨水的宽度升高时,需要专用驱动电路或者需要专用的电极来形成墨水升高。 根据本发明的记录装置,在具有狭缝状开口部的支撑体上设置倒角或台阶等机械加工,或者对被加工部分涂布斥油溶剂等表面处理。 由于这样的结构,可以使开口部的横向上的油墨的宽度不变化,而不用电动驱动等方法,从而确保了点的稳定印刷。 此外,通过增加开口部分的中心部分附近的开口部分的上升宽度,可以防止打印点的直径在纵向方向上变得不均匀 开口部分。

    • An electronic timepiece has a thermoelectric element for generating an electromotive force in response to a temperature difference thereacross. A booster circuit boosts the electromotive force generated by the thermoelectric element. A storage mechanism stores electrical power utilizing the electromotive force boosted by the booster circuit. A power monitoring circuit monitors the electromotive force boosted by the booster circuit to detect whether the boosted electromotive force is lower than a threshold value. An oscillation circuit is driven by electrical power stored in the storage mechanism. A dividing circuit frequency-divides a signal output by the oscillation circuit. A display mechanism is driven by a display driving circuit to display time in accordance with an output signal from the dividing circuit. A display drive controlling circuit stops operation of the display driving circuit when the power monitoring circuit detects that the boosted electromotive force is lower than the threshold value.
