Title: Multiple layer film optical element for x-ray
Inventor: NISHIDA EMIKO
IPC: G21K1/06
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce size, lower the price and make accurate an X-ray optical apparatus by layering light element layer fraren and heavy element layers by turns to be polymerization fullerene. SOLUTION: By irradiating fullerene layer Fn with Ar laser, the fraren molecules in the fullerene layer mutually combine to be complex fraren. By this, reflection factor effectively increases. By repeating formation of heavy element layer Hn, formation and combination of fraren layer Fn, a multiple layer film reflection mirror making the layer Fn to be complex fraren is formed. When fraren is overlapped, spherical structure of the fullerene is destroyed and mutually combined and so the surface becomes smoother than in the case fullerene monomer is simply layered. By using complex fraren in this manner, larger reflectivity can be obtained. Furthermore by using polymerization fullerene it can be made more resistive and superior in photo-resistivity and thermal resistivity.

Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To increase the electric charge amount of developer, to suppress the lowering of image density or fogging when an image is formed after a device is stopped in a long term and to form the high-definition image by rotating a developer carrier at a higher speed than the normal speed of an image forming time in a prescribed time before the first image is formed when the image is formed after the device is stopped for a long term. SOLUTION: When it is judged that the image forming device is stopped in a long term, the developing sleeve 11 is rotated at the higher speed Vdhms than the normal speed Vdhmn of the image forming time by setting the rotating time Tdhms being as the prescribed time based on time Tdhma before the first image is formed. Then, it is good that the rotating speed Vdhms is set to be higher and the rotating time Tdhms is set to be longer as the time Tdhma is longer. Besides, developing bias is not applied in the time Tdhma and the potential of a covering member 18 is set to be identical to that of the sleeve 11. Thus, toner whose electric charge amount is insufficient is prevented from being splashed to the inside of the device.
