The plane structure of the rugged shaped 9 is concentric and an optical disk 7 is housed between the two cartridges 1 and 1 formed with the rugged shapes 9. The flow of the air is generated between the cartridges 1 and 1 and the optical disk 7 by the rotation of an optical disk and is discharged outside the cartridges 1 from the apertures of the cartridges 1 along the rugged shapes 9. In addition, the dust adhered to the surface of the optical disk 7 may also be removed by the generation of the air flow along the rugged shapes 9.

IPC: G02B27/30
Filed: 1985-07-15
Abstract: PURPOSE:To form a collimator lens which has extremely small residual aberrations and sufficiently long operation distance and is easily handled by specifying relations among the focal length of the whole lens system, the thick ness of a parallel plane plate, the focal length of the 2nd lens group, the radius of curvature of the 1st surface of the 1st lens, and the radius of curvature of the 2nd surface of the 2nd lens. CONSTITUTION:Equations (1)-(3) hold, where (f) is the focal length of the whole lens system, d3 the thickness of the parallel plane plate, f2 the focal length of the 2nd lens group, r5 the radium of curvature of the 1st surface of the 1st lens, and r6 the radius of curvature of the 2nd surface of the 2nd lens. The expressions (1) and (2) are for reducing the residual spherical aberration. The equation (3), on the other hand, limits the shape of the 1st lens group; sine condition enters an overcompensation state above the upper limit while the spherical aberration is compensated excellently and enters an under compensation state below the lower limit, so this lens is not suitable to a collimator lens.

Title: Manufacture of composite metallic wire
Inventor: KAWAGOE HAJIME
IPC: B21C23/00
Filed: 1983-08-24
Abstract: PURPOSE:To prevent the breakage of a core at the time of starting extrusion by joining a wire material having high tensile strength to a core wire to use it as the core wire in a specific range at the time of starting its extrusion in manufacturing a composite metallic wire by extrusion. CONSTITUTION:An aluminum 4 is coated on the circumference of a core wire 8 having low tensile strength such as a mild steel one, and a composite metallic wire is manufactured as an aluminum coated steel wire 6 by extruding it through a die 5 of a fixed shoe block 2. At that time, the wire is often broken at the time of starting its extrusion because of large static friction between the coating material Al of the surface and the core wire 8 made of mild steel, etc. In this case, a wire 7 having high tensile strength such as a hard steel wire or music wire is welded 9 to the mild steel core wire 8 before extruding it. The wire 7 is strong enough for a drawing force at the starting time of extrusion, and not to break; as the static friction transfers to a dynamic one thereafter, a composite metallic wire is continuously extruded without causing a breakage of core wire, even if it has low tensile strength such as a mild steel one.

Title: Threshold matrix and method and device for reproducing gradation using it
Inventor: SUZUKI TAKASHI
IPC: H04N1/405
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To obtain an image having excellent uniformity in dot distribution with a small-sized mask by configuring the device so that a virtual image of a visually unpreferable level is not produced in an output image in the case that an input image is gradation-processed and an output device with precision of a specified value or over outputs the processed image. SOLUTION: A dot pattern produced in a pixel block of a reference size by using a mask of a size smaller than the pixel block of the reference size has a non-blue color noise characteristic in all gradations. In the case that gradation processing is applied to an input image and the processed image is outputted by an output device having resolution of about 600 dpi, a virtual image having a contrast of a visually preferable level such as moire and a prescribed repetitive pattern caused by the mask itself is not produced in the output image. A gradation processing unit 103 includes a memory 104 for storing a threshold matrix 105 and a comparator 106 that compares a gradation number of each of input pixel with a corresponding threshold value and decides 0 or 1 as an output value depending on the comparison result.
