    • An X-ray generator includes a hermetically sealed main generator unit, and an electron gun and a target housed inside the main generator unit, and bombards the target with electrons emitted from the electron gun and passes an X-ray beam emitted from the surface of the target owing to the bombardment to the exterior through an exit window. An X-ray optical element is provided inside the main generator unit on the output path of the X-ray beam emitted from the target for regulating the X-ray beam and the X-ray beam regulated by the X-ray optical element is passed through the exit window. This configuration improves the durability of the X-ray optical element and enables the length of the X-ray path to the X-ray irradiation point to be shortened so as to suppress attenuation of the emitted X-ray beam by air resistance and thereby reduce power consumption.

    • An incident monochromator and a microfocus X-ray source with an apparent focal spot size of less than 30 micrometers are combined so that the X-ray source can be close to the monochromator and the intensity of X-rays focused on a sample is greatly increased. A side-by-side composite monochromator is arranged between the X-ray source and the sample. The composite monochromator has a first and a second elliptic monochromators each having a synthetic multilayered thin film with graded d-spacing. The first elliptic monochromator has one side which is connected to one side of the second elliptic monochromator. A preferable apparent focal spot size D of the X-ray source may be 10 micrometers. Because the invention provides a high focusing efficiency for X-rays, it is not required to use a high-power X-ray tube. The X-ray tube according to the invention, moreover, may have a stationary-anode, whose power may be about 7 Watts.
    • 组合入射单色仪和视点焦点尺寸小于30微米的微焦点X射线源,使得X射线源可以靠近单色仪,并且聚焦在样本上的X射线的强度大大增加 。 在X射线源和样品之间设置并排的复合单色仪。 复合单色仪具有第一和第二椭圆形单色器,每个具有分级d间距的合成多层薄膜。 第一椭圆单色仪具有连接到第二椭圆单色仪的一侧的一侧。 X射线源的优选视点焦点尺寸D可以为10微米。 由于本发明为X射线提供高的聚焦效率,所以不需要使用大功率的X射线管。 此外,根据本发明的X射线管可以具有固定阳极,其功率可以为约7瓦。

    • The present invention is aimed at providing a control system for a thermal fixing apparatus having an excellent fixing ability even at an initial stage of a copying process when applied to a high speed copying machine and ensuring a longer life of a surface layer member of the roller, while maintaining the economical benefit derived from the provision of a heater only in a heat roller. The fixing apparatus includes a heater roller 101 and a press roller 102. At least one of the rollers is driven by a motor 103 while in contact with the other so that both rollers are rotated together. A surface temperature of the heater roller 101 is detected by a thermometer 104 and is used for controlling a heating level of a heater 106 by a controller 105. A standby stage controller 110 stops the rotation of the motor 103 if it is determined that the surface temperature of the press roller detected by a thermometer 107 is higher than the upper limit temperature, and outputs a command for rotating the motor 103 if it is determined that the surface temperature of the press roller is lower than the lower limit temperature.
