摘要： A plurality of magnetic styli are arranged in a row for effecting a line recording. A magnetic styli are magnetized by a magnet held in contact with these styli so that a magnetic fluid attaching to the styli is protruded from each stylus to form continuous wave-like protrusions along the row of the styli. The magnetic fluid protruded from the styli is to fly or migrate as a high voltage is applied selectively between the styli and a control electrode which opposes to the styli across the recording paper, due to a Coulomb force acting on the ends of the protrusions. In consequence, a recording is made by the magnetic fluid serving as an ink on the recording paper in accordance with a recording signal. A predetermined head or height differential is preserved between the magnet and an ink tank. The magnet and the ink tank are connected to each other by means of a pipe filled with the magnetic fluid. A slight gap is formed in the connection between the pipe and the magnet. This gap, however, is completely covered and closed by the magnetic fluid attaching to the magnet so that the ambient air is prevented from coming into the pipe. A vacuum is generated in the pipe due to the aforementioned height differential to control the amount of the magnetic fluid supplied to the magnet. As the magnetic fluid is consumed progressively at the ends of the protrusions, the magnetic fluid is supplied to the protrusions from the ink tank through the pipe and the gap. In consequence, various troubles such as printing failure due to magnetic thickening of the magnetic fluid which inevitably takes place in the conventional apparatus incorporating an elongated magnet type ink supplying device, is completely eliminated to ensure a stable printing of a high quality.

摘要翻译： 多个磁针被排列成一行以进行线记录。 一个磁性测针由与这些测针保持接触的磁体磁化，使得附着在测针上的磁性流体从每个触针突出，以沿着测针的一行形成连续的波浪形突起。 由于作用在突起的端部上的库仑力，由于从触针突出的磁性流体是飞行的或迁移的，因为高电压被选择性地施加在触针和与记录纸对准的测针的控制电极之间。 因此，根据记录信号，通过用作墨水的磁性流体在记录纸上进行记录。 在磁体和墨水罐之间保留预定的头部或高度差。 磁体和墨水罐通过填充有磁性流体的管道相互连接。 在管和磁体之间的连接中形成微小的间隙。 然而，该间隙被附着在磁体上的磁性流体完全覆盖和闭合，从而防止环境空气进入管道。 由于上述高度差，在管中产生真空，以控制供给到磁体的磁性流体的量。 当磁性流体在突起的端部逐渐消耗时，磁性流体通过管道和间隙从墨水罐供应到突起。 结果，完全消除了在包含细长磁体型供墨装置的传统装置中不可避免地发生的磁性流体的磁性增厚引起的打印故障等各种问题，以确保高质量的稳定印刷。

摘要： The present invention is related to an angular velocity sensor, and intends to improve the detection characteristic through a precise measuring of an angular velocity signal. For this objective, the invented angular velocity sensor comprises U-shape first and second piezoelectric elements(4),(5) bonded together sandwiching a detection electrode(6), wherein in at least one of the tuning fork arms(4a),(5a) the first and second piezoelectric elements(4),(5) are polarized in a direction of thickness along which the piezoelectric elements are bonded together. Driving electrodes(7),(12) and (8),(11) provided in diagonal arrangement on the tuning fork arm are supplied with driving signals inverse-phased to each other. In such a structure, the driving signals cancel to each other at the vicinity of detection electrode; as a result, the driving signals never mix with a detection signal to be detected by the detection electrode(6). Thus, the capability of detecting an angular velocity signal is improved.
