摘要:
A laser attachment device of the present invention is formed of a LD package and a LD holder housing it. A first inner wall of the LD holder to come into contact with a side surface of the LD package is an inclined surface. This allows the facing direction of the LD package to be corrected by the first inner wall being the inclined surface, even when a laser beam emitted from a light emitting chip housed in the LD holder is inclined with respect to an optical axis. Thus, the traveling direction of the laser beam is corrected to the optical axis side.

One purpose of the invention according to one embodiment is to provide a magnetic recording apparatus of high recording density in which magnetization transition curvature amount of a recording pattern is small. In one embodiment, the center of a heating area is arranged at a track edge side of a recording pattern as compared with the width-direction center position of a main magnetic pole of a recording head, and a recording magnetic field is applied while a medium is locally heated at the time of signal recording. A switching magnetic field of the medium is locally reduced by heating, so that a line where the switching magnetic field of the medium is equal to the recording magnetic field from the head approaches the heating center position, and a desired recording pattern in which the transition curvature amount is reduced can be realized. Other systems and methods are also presented.

The radiographic X-ray device according to this invention is constituted in such a way that positional relation detecting unit 25 detects in real time the information regarding the positional relations between X-ray imaging systems 4 and 8 that thoroughly represents the overall current status of the positional relations of external surfaces of both X-ray imaging systems 4 and 8 where collisions between first and second X-ray imaging systems 4 and 8 may occur, that the information regarding the positional relations detected by positional relation detecting unit 25 is taken into consideration in controlling the motions of X-ray imaging systems 4 and 8, and that the current status of the positional relations of external surfaces of both X-ray imaging systems 4 and 8 can be thoroughly and accurately reflected upon the motions of X-ray imaging systems 4 and 8 without any difficulty, so that any collisions of X-ray imaging systems 4 and 8 can be avoided without fail.
摘要:
An image forming apparatus includes: a plurality of rollers; and an endless belt wound around said rollers, said rollers including: a driving roller which drives said belt wound around said rollers and a driven roller set which is driven by said driving roller via the movement of the endless belt, said driven rollers having one or more metal rollers. At least one of said metal rollers is a smooth roller which satisfies following conditions (i) and (ii); (i) a surface roughness Rz≦2 μm; and (ii) an arithmetic inclination average Δa≦0.06; where said Δa is obtained from an equation (1) below: Δ a = 1 L ∫ 0 L x f ( x ) x ( 1 ) where L=a reference length taken from a roughness curve; f (x)=a height of the roughness curve at a position x within said reference length L along a lengthwise direction of the roller.
摘要:
Disclosed is an image forming apparatus, which comprises an intermediate transfer belt (15), and a plurality of image-forming units (11) to (14) disposed along the intermediate transfer belt (15) and adapted to form toner images of different colors and sequentially transfer the toner images onto the intermediate transfer belt (15) in a superimposed manner so as to form a color toner image. The intermediate transfer belt (15) is laid across a drive roller (16), a driven roller (17) and a tension roller (18), in a tensioned condition. A rotation speed of the tension roller (18) adapted to apply a tension to the intermediate transfer belt (15) is detected to obtain a linear speed of the intermediate transfer belt (15). In a process of color-misregistration correction, a write-start timing for each toner image of the colors is adjusted based on the linear speed of the intermediate transfer belt (15).
