Filed: 1984-12-17
Abstract: PURPOSE:To separate a chrominance signal and a luminance signals and to improve picture quality of a picture in the vertical direction by deforming a comb line filter of digital type constituted by connecting two 1H delay lines in series. CONSTITUTION:Composite video signals are digitalized by an A/D converter 1 and supplied in series to the first and second delay lines 7, 8. Each of them is multiplied by a coefficient, added by an adder 10 and supplied to a color band pass filter 11 to obtain a color difference signal C-Y. A 2H type comb line filter is constituted of the delay lines 7, 8 and the adder 10. Difference of input/output signals is taken out respectively by subtracters 12, 13, added by an adder 14 and multiplied by a coefficient through an LPF15 to obtain a vertical peaking signal. A luminance signal Y is obtained by subtracting the color difference signal C-Y from output signal of the first delay line 7 by a subtracter 18, and a corrected luminance signal is obtained by adding the vertical peaking signal by an adder 16.

Title: Device for measuring shape of aspheric surface
Inventor: NAKAYAMA SHIGERU
IPC: G01B11/24
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a device capable of measuring the whole shape of an aspheric surface by one operation by transforming spherical waves to be reference into spherical waves corresponding to an aspheric test surface with respect to spherical waves diffracted by a pinhole. SOLUTION: A reflecting surface to create a point light source is arranged between a light source 1 and a test surface. A beam of light for reference is a beam of light emitted from the point light source, and a beam of light for measurement is a beam of light emitted from the point light source and reflected by a reflecting surface. Then an optical element to transform spherical waves into desired aspheric waves is arranged in an optical path between the point light source and a test surface 5. With respect to spherical waves diffracted by a pinhole 3, spherical waves to be reference are transformed into aspherical waves corresponding to the aspheric test surface 5. Or aspheric waves generated by the reflection of the spherical waves to be reference at the aspheric test surface 5 are transformed into spherical waves and plane waves.  By making intervals of interference fringes in the whole surface of an aspheric test surface coarse through the use of what is called a null element 4, it becomes possible to measure the whole shape of the aspheric surface by one operation.

CONSTITUTION:This Al alloy sheet has a composition consisting of, by weight, 0.8-1.3% Mn, 0.2-0.7% Si, and the balance Al. In order to manufacture this sheet metal, an ingot of an Ag alloy with the above composition is hot-rolled at about 350-450 deg.C, without being subjected to homogenizing treatment, and is then subjected to a single process annealing only between primary cold rolling and secondary cold rolling at about 350-420 deg.C and further to secondary cold rolling at about 20-40% draft.
