Title: Sheet feeder and image forming device
Inventor: KOMINATO TAKANARI
IPC: B65H3/06
Filed: 1995-02-20
Abstract: PURPOSE: To provide a sheet feeder by which separation of sheets can be surely carried out after a drive is stopped by means of a retard roller system. CONSTITUTION: When separation of sheets is carried out by means of a conveying roller 106 and a reversely rotating separation roller 108 in a multiple paper feeding part, in a free size mode, a drive of the conveying roller 106 is cut off by means of a clutch 138 at the timing when the rear end of a minimum size sheet passes through between the rollers 106, 108. In feeding of a large size sheet, a drive is cut off at the same timing, however, in this process, the second sheet is prevented from overlapping with the first one by reversely rotating the separation roller 108.

Abstract: PURPOSE:To facilitate the manufacture of a compound optical system consisting of three lens elements, by forming those lens elements into an asymetric optical system and by providing a light absorber at outer circumference among respective lenses. CONSTITUTION:A luminous flux from one point 11 off the optical axis and on subject surface 8 is focused on intermediate image point 11' of intermediate image- formation surface 6 via image-forming lens 1 and then made into scattering light, and only the luminous flux in beams 13 and 14 is focused on final image point 11'' on image surface 9 via lens 2 and image-forming lens 3 to form a regular image of unmagnification. Although the transmission efficiency of the quantity of light in the required visual field of lens 2 is 100%, the efficiency decreases from the center of the visual field to the circumference and becomes zero at the maximum visual field part. The luminous flux of less than the solid angle in the range shown by light beams 14 and 15 in the luminous flux from one point 11 is absorbed by light absorbers 4 and 5 and never reaches image point 11''. Therefore, nealy gausslike light intensity disribution appears on image surface 9 and when those lens elements are aligned, nearly uniform light quantity distribution AA' can be obtained.

Title: Dividing method for wafer using laser light
Inventor: YASUAMI SHIGERU
IPC: H01L21/268
Filed: 1981-03-09
Abstract: PURPOSE:To prevent the production of a crack due to the concentration of a thermal strain by emitting a beam of low energy density in the step after and before the melting and emitting step, and performing a preliminary heating and annealing, thereby alleviating the thermal gradient of a wafer in the vicinity of exposed region. CONSTITUTION:A laser beam oscillated by a laser oscillator 1 is condensed onto the surface to be machined via a condensing lens 4 through a Y mirror Z using Y-axis scan and an X mirror 3 using X-axis scan, thereby machining such as cutting of the groove. In this case, the beam coming from the mirror 3 is divided by a beam splitter 5 into a main beam and two sub beams. The intensity ratio of the main beam to the sub beams thus divided by the splitter 5 alleviates the temperature gradient produced at the workpiece in the vicinity of the surface to be machined, thereby sufficiently annealing the material in the course of machining. Accordingly, cracks produced by the thermal strain of the material upon machining can be suppressed to minimum limit.
