    • An image forming apparatus includes a developing device including a developing roller to bear a developing agent to develop a latent image formed on an image bearing member, a cooling device to reduce an internal temperature of the image forming apparatus, a controller to calculate a travel distance of the developing roller to control the cooling device, and a memory unit to store the total travel distance of the developing roller. The controller calculates the total travel distance of the developing roller every Y minutes in the last X minutes, and a difference between the latest total travel distance of the developing roller and the total travel distance stored Z minutes ago by the memory unit to obtain the total travel distance during Z minutes and operate the cooling device for W minutes after image forming operation where the difference is equal to or greater than a threshold value M.

    • The present invention relates to a photomultiplier having a fine configuration capable of realizing stable detection accuracy. The photomultiplier has a housing whose inside is maintained vacuum, and a photocathode, an electron-multiplier section, and an anode are disposed in the housing. In particular, one or more control electrodes disposed in an internal space of the housing which surrounds the electron-multiplier section and the anode are electrically connected via one or more connection parts extending from an electron emission terminal of the electron-multiplier section. In this configuration, due to a voltage, instead of the applying between an electron entrance terminal and the electron emission terminal of the electron-multiplier section, being applied between the electron entrance terminal and the control electrodes, an electric potential gradient which is increased gradually from the photocathode side toward the anode side is formed in the electron-multiplier section, and a sufficient electric potential difference is provided between the electron emission terminal of the electron-multiplier section and the anode, which makes it possible to obtain stable detection accuracy.
    • 本发明涉及具有能够实现稳定的检测精度的精细结构的光电倍增管。 光电倍增管具有内部保持真空的壳体,并且光电阴极,电子倍增器部分和阳极设置在壳体中。 特别地,设置在外壳的内部空间中的一个或多个控制电极,其围绕电子倍增器部分和阳极通过从电子倍增器部分的电子发射端延伸的一个或多个连接部分电连接。 在该结构中,由于电压而不是在电子入射端子和电子倍增器部分的电子发射端子之间施加,而被施加在电子入射端子和控制电极之间,逐渐增加的电位梯度 在电子倍增部形成从光电阴极侧朝向阳极侧,在电子倍增部的电子发射端与阳极之间设置充分的电位差,能够得到稳定的检测精度。

    • A liquid discharge head includes plural heat generating members, each linearly communicating with a discharge port, a liquid flow path communicating with each discharge port and having a bubble generating area in which a movable member is provided, a limiting portion opposed to the bubble generating area in the liquid flow path for limiting displacement of the movable member, and a circuit for receiving data of a predetermined number of bits for each heat generating member and generating drive pulses for each heat generating member based on the respective input data. Substantial contact between the displaced movable member and the limiting portion renders a portion of the liquid flow path including the bubble generating area a substantially closed space except for the discharge port. The number of drive pulses generated from the input data is larger than the predetermined number of bits for at least one set of the data.
