Title: Steel for prehardening metal mold for plastic molding
Inventor: OKUNO TOSHIO
IPC: C22C38/42
Filed: 1986-11-04
Abstract: PURPOSE:To provide a steel for molds combining high machinability with high toughness, by forming a steel of low C- medium - low Mn - Ni - high Cu - Al type having a specific composition. CONSTITUTION:This steel for molds has a composition consisting of, by weight, 0.07-0.16% C, <=0.60% Si, 0.60-1.50% Mn, 2.50-3.50% Ni, 0.30-0.90% Al, 1.80-2.50% Cu, and the balance Fe. To this steel, <=0.60% Cr and/or Mo and W, independently or in combination, in an amount satisfying 1/2W+Mo=0.10-0.70% may be added. In this steel, a uniform upper bainite structure is formed by hardening, and further, Fe-Cu, Ni-Al intermetallic compounds, and Mo(W) carbides are precipitated in a low-C bainite matrix by means of tempering at a temp. as high as >=500 deg.C so as to provide strength due to age hardening. Simultaneously, moderate embrittlement is produced, so that superior machinability can be provided and also moderate toughness to breakage to be developed from the thin-wall part of a mold during use can be maintained.

Title: Picture reading device
Inventor: SAITO HIROSHI
IPC: H04N1/19
Filed: 1986-11-04
Abstract: PURPOSE:To properly correct the variance of sensitivity, a secular change, etc., of a picture reading element with an extremely simple constitution of a device that projects the picture of a picture recording medium and reads the picture by the picture reading element via a Fresnel lens, by providing an unrugged part at a position near the optical axis of at least a projecting optical system of the Fresnel lens. CONSTITUTION:A Fresnel lens 10 contains an unrugged part 15 formed at the center part near an optical axis C of a projecting optical system. The variance of sensitivity, the secular change or the variance of the illuminating light quantity of a sensor like a CCD, etc., are corrected by means of a reference picture before pictures are read. In this case, the electrical shading is applied to the pictures which are projected via the part 15 of the lens 10. As a result, the picture undergoing the electrical shading never produces the periodical bright/ dark areas. Thus the reference picture can be accurately read and the proper correction can be secured.

Title: Three-dimensional pattern for calibration
Inventor: FURUYAMA TSUNEO
IPC: H04N5/222
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To provide an accurate calibration even with zooming with one pattern, by creating a calibration pattern by changing a photographing magnification by zooming so that average grain size of a photographed image of the photographed pattern is uniformed. SOLUTION: A calibration pattern 10 is cubic, a front surface 11, an upper surface 12, and a left surface 13 are provided with a pattern of the same size, a part at an origin O in three-dimensional coordinates is small in size, and the size increases outward. Respective surfaces of the pattern need not same, but coordinates of a marked point, for example a corner point of a black portion having oblique lines are made clear. Therefore, a size with a large number of digits and a size with a irrational number are avoided, and each pattern for forming the pattern is a pattern easy to provide a corresponding point and is not limited to square and rectangle.  For example, when a checkered pattern in which the size is changed in geometrical series is applied a substantially same pattern goes into a photographing screen regardless of zooming, reference point coordinates are easily determined, and calibration is facilitated.
