    • A normally-closed electromagnetic relay which may be used in controlling a supply of electric current to an automotive engine starter. The electromagnetic relay is equipped with a resistor and a shirt circuit. The short circuit is created by closing of relay contacts when a relay coil is energized to establish an electric connection between ends of the resistor to supply the current from a battery to an electric motor without flowing through the resistor and opened by opening of the relay contacts when the relay coil is deenergized to supply the electric current from the battery to the electric motor through the resistor. If a motor drive signal line leading to the electromagnetic relay is disconnected when the relay coil is kept energized, it will cause the short circuit to be established to ensure the supply of current to the motor, which also avoids the melting down of the resistor.
    • 常闭电磁继电器,可用于控制向汽车发动机起动器供电的电流。 电磁继电器配有电阻和衬衫电路。 当继电器线圈通电时,通过关闭继电器触点来建立短路,以在电阻器的端部之间建立电连接,以将电流从电池供给到电动机而不流过电阻器并且通过打开继电器触点而打开 当继电器线圈断电以通过电阻器将电流从电池供给到电动机时。 当继电器线圈保持通电时,如果导通电磁继电器的电机驱动信号线断开,则会导致短路建立,以确保电机的电流供应,这也避免了电阻器的熔化。

    • There is provided an image stabilizing apparatus which is capable of keeping a toner concentration and a printing density constant when toner consumption is small, and further which is systematically simple. The image stabilizing apparatus comprises a control portion for controlling a toner replenishment amount in a toner replenishing apparatus depending on a toner concentration detected by a toner concentration sensor and a print coverage of a document detected by a print coverage detecting portion, and controlling, when the print coverage of the document detected by the print coverage detecting portion is less than a predetermined value and such documents continue, so as to discharge a predetermined amount of toner to the image bearing member by developing forcibly, and then replenish the same amount of toner as the predetermined amount by the toner replenishing apparatus.
    • 提供了一种图像稳定装置,其能够在调色剂消耗量小时保持调色剂浓度和印刷密度恒定,并且进一步系统地简单。 图像稳定装置包括控制部分,用于根据由调色剂浓度传感器检测的调色剂浓度和由打印覆盖检测部分检测到的原稿的打印覆盖率来控制调色剂补充装置中的调色剂补充量,并且当 由打印覆盖检测部分检测到的文档的打印覆盖率小于预定值,并且继续这样的文档,以便通过强制显影将预定量的调色剂排出到图像承载部件,然后补充相同量的调色剂 调色剂补充装置的预定量。

    • Terminal-bolts and a fixed contact are formed with different kinds of metals, and fixed to a fixing hole formed in the fixed contact by press fitting one end of the terminal-bolts. A plurality of concavo-convex parts is provided on a surface of the fixed contact that faces the movable contact. A plurality of concavo-convex portions is provided on another surface of the fixed contact that faces an anti movable-contact side. The concavo-convex portions are arranged so that positions of concave parts of the concavo-convex portions match positions of convex parts of the concavo-convex portions provided in the opposite surface of the fixed contact. The concavo-convex parts are at least partly curved, and have the same height and project in a height direction from the fixed contact.
    • 端子螺栓和固定触点由不同种类的金属形成,并通过压配接头螺栓的一端固定在固定触点上形成的固定孔。 多个凹凸部分设置在固定触头的面对可动触点的表面上。 多个凹凸部分设置在固定触头的面对抗可动触点侧的另一表面上。 凹凸部的布置使得凹凸部的凹部的位置与设置在固定触点的相对表面中的凹凸部的凸部的位置相匹配。 凹凸部至少部分弯曲,并且具有与固定触点高度相同的高度和突起。
