    摘要： Disclosed is an environment-friendly, pH-neutral, loaded stream extinguishant and a method for preparing the same. The extinguishant is prepared from a mixture of a fire extinguishable component, an organic acid, a surfactant and water. It is very effective in controlling A class fires, as well as showing excellent flame retardance. Also, the extinguishant is neutral in pH so as to neither corrode extinguisher parts, nor affect soil negatively. It can be also applied to portable extinguishers.

    摘要： An ink jet printer head having nozzles, actuators, a multiplexer, and actuator finding circuits of a matrix method. The multiplexer is capable of single-input and multiple output. The actuator finding circuits of the inkjet printer head include electronic switches arranged in rows and columns. The nozzles have the actuators, and the actuators are controlled by the electronic switches. The multiplexer receives a signal in accordance with the conveyance direction and position of the ink jet printer head, and sequentially outputs the signal to the actuator finding circuits in accordance with the signal it received, thereby sequentially selecting a nozzle group in the rows. In this situation, when an external print data signal is inputted to the actuator finding circuits to select a nozzle group in the columns, the corresponding electronic switch drives the actuator, so that the ink is ejected out of the nozzle. Accordingly, by using the multiplexer having only one external input terminal, the increment of the number of pads is decreased when the number of ink jet printer head nozzles is increased.

    摘要翻译： 具有喷嘴，致动器，多路复用器和矩阵法的致动器查找电路的喷墨打印头。 多路复用器能够进行单输入和多输出。 喷墨打印机头的致动器发现电路包括以行和列布置的电子开关。 喷嘴具有致动器，并且致动器由电子开关控制。 多路复用器根据喷墨打印头的传送方向和位置接收信号，并根据接收到的信号依次将信号输出到致动器寻找电路，从而依次选择行中的喷嘴组。 在这种情况下，当将外部打印数据信号输入到致动器寻找电路以选择列中的喷嘴组时，相应的电子开关驱动致动器，使得墨水喷射出喷嘴。 因此，通过使用仅具有一个外部输入端子的多路复用器，当喷墨打印头喷嘴的数量增加时，焊盘数量的增加减小。

    摘要： An electric motor includes a stator frame carrying a coil, and a rotor bushing carrying a magnet. The coil rotates the rotor bushing relative to the stator housing about a vertical axis. The stator frame and rotor bushing together form a cavity in which a spherical bearing is disposed. The rotor bushing includes a contact member engaging an upper portio of the spherical bearing with a point contact, to transfer the weight of the rotor bushing to the spherical bearing. The axis passes through the cavity and the spherical bearing. An outer cylindrical surface of the rotor bushing faces a cylindrical inner surface of the cavity and has grooves formed therein for drawing-in air.

    摘要： Disclosed is a motor including a stator, a rotor cooperating with the stator, a rotating shaft rotating with the rotor, the rotating shaft being provided in its bottom with a receiving space, and a semi-spherical bearing disposed in the receiving space of the rotating shaft. The semi-spherical bearing is truncated to define a planar portion and part of the receiving space is defined by a surface corresponding to the planar portion. The planar portion is provided with a plurality of grooves formed in a spiral-shape to allow for suction of air for smooth rotation.
