    • Disclosed is a metal-based carbon fiber composite material exhibiting an improved thermal expansion coefficient, improved thermal conductivity, and is smaller in weight, and a method for producing the same. The composite material includes a metal and a carbon fiber including a micron carbon fiber and a nanofiber; the composite material having a first surface; the micron-size carbon fiber being oriented in one direction parallel to the first surface and being continuous from end to end; at least 80% of the nanofiber being oriented at an angle within 30° with respect to the first surface; and the nano-size carbon fiber being oriented randomly in a plane parallel to the first surface. In the composite material, a surface region may include a smaller amount of micron carbon fiber than other regions, or include no micron carbon fiber; the nanofiber may have an orientation parallel to the surface of the composite material.
    • 公开了一种具有改善的热膨胀系数,改进的导热性和较小重量的金属基碳纤维复合材料及其制造方法。 复合材料包括金属和包含微米碳纤维和纳米纤维的碳纤维; 所述复合材料具有第一表面; 微米级碳纤维在平行于第一表面的一个方向上定向并且从一端到另一端是连续的; 至少80%的纳米纤维相对于第一表面以30°的角度取向; 并且纳米尺寸碳纤维在平行于第一表面的平面中随机取向。 在复合材料中,表面区域可以包括比其它区域更少量的微米碳纤维,或不包括微米碳纤维; 纳米纤维可以具有平行于复合材料表面的取向。

    • A fixing device fixes a toner image on a recording medium. The fixing device includes a heat source that converts electric power into heat and a fixing member that gives the heat generated by the heat source to the recording medium on which the toner image is formed. The fixing device includes a safety circuit that forcibly interrupts voltage supplied from a power supply to the heat source if the temperature in the device detected by a temperature detection sensor exceeds reference temperature. The fixing device has a malfunction preventing circuit that stops the operation of the safety circuit in order to prevent the voltage supplied to the heat source from being forcibly interrupted when the voltage of the power supply supplied to the heat source is unstable.
    • 定影装置将调色剂图像固定在记录介质上。 定影装置包括将电力转换成热量的热源和将由热源产生的热量提供给形成有调色剂图像的记录介质的固定部件。 如果由温度检测传感器检测到的设备中的温度超过参考温度,则固定装置包括强制中断从电源向热源供应的电压的安全电路。 定影装置具有阻止安全电路的动作的故障防止电路,以防止供给到热源的电源的电压不稳定时供给到热源的电压被强制中断。
