    • A continuous denitration apparatus capable of ensuring mass processing of a nitrate solution of a nuclear fuel and a continuous stable operation. By a rotation of screws, uranium nitrate solution supplied from a liquid feed inlet is continuously conveyed. A trough is divided into a concentration zone, a denitration zone and a drying zone. Microwaves emitted from a microwave incident inlet pass through a microwave permeable part provided in a critical shield plate for covering the upper part of the trough and are applied to the uranium nitrate solution of high concentration and high viscosity, conveyed by the screws. The uranium nitrate solution is denitrated to prepare a denitrated product (uranium trioxide). This denitrated product is dried in the drying zone to obtain powder to be discharged from an outlet. The deposition adhering to the screws in the concentration zone can be exfoliated by moving the microwave permeable part a little to the concentration zone side to prevent a blocking of the rotation of the screws. In the drying zone, local heating by the microwaves can be prevented.
    • 一种连续脱硝装置,能够确保核燃料的硝酸盐溶液的大量加工和连续稳定的运行。 通过螺杆旋转,连续输送从液体进料口供给的硝酸铀溶液。 槽分为浓缩区,脱硝区和干燥区。 从微波入射口射出的微波通过设置在临界屏蔽板上的微波透过部分,用于覆盖槽的上部,并被施加到由螺钉输送的高浓度和高粘度的硝酸铀溶液中。 将硝酸铀溶液脱硝以制备脱硝产物(三氧化铀)。 将该脱硝产物在干燥区中干燥,得到从出口排出的粉末。 通过将微波可渗透部分稍微移动到集中区域侧,附着在浓缩区域中的螺钉的沉积物可以被剥离,以防止螺钉的旋转阻塞。 在干燥区,可以防止微波局部加热。

    • A fixing device is disclosed, including: a fixing rotative body, a heat source, and a control part. The control part conducts a printing temperature control which varies an ON ratio per unit time of the heat source based on a detection result of the temperature detecting part to maintain a printing target temperature in a printing state, conducts a waiting temperature control which performs an ON/OFF control based on the detection result of the temperature detecting part to maintain a waiting target temperature in a waiting state after a printing operation ends, and conducts a forcible ON control which forcibly turns on the heat source for a predetermined time before starting the ON/OFF control when the detection result of the temperature detecting part after the printing operation ends is lower than the waiting target temperature.

    • A fixing device includes a separator presser that presses against a plurality of separators to separate the plurality of separators from a fixing rotary body that contacts an opposed rotary body to form a fixing nip therebetween through which a recording medium bearing a toner image passes. A single driver is connected to the separator presser to separate the separator presser from the plurality of separators. An entering recording medium detector is disposed upstream from the fixing nip in a conveyance direction of the recording medium to detect the recording medium. A controller is connected to the driver to control the driver based on a detection signal sent from the entering recording medium detector to change a contact time period for which the plurality of separators contacts the fixing rotary body.
    • 一种定影装置包括一个分离器按压件,其压靠多个分离器以将多个分离器与接触相对旋转体的定影旋转体分离,以形成一个定影夹持部,通过该定影夹持器,带有调色剂图像的记录介质通过该定影夹持器。 单个驱动器连接到分离器压脚以将分离器压脚与多个分离器分离。 进入的记录介质检测器在记录介质的输送方向上设置在定影辊隙的上游,以检测记录介质。 控制器连接到驱动器,以基于从进入的记录介质检测器发送的检测信号来控制驱动器,以改变多个分离器与定影旋转体接触的接触时间段。
