Title: Optical wavelength variable filter
Inventor: NAKAMURA KEIJI
IPC: G02F1/01
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an optical wavelength variable filter at a low cost in an integrated state. SOLUTION: Electrodes 331 to 333 made of metal thin films having grating structures corresponding to wavelength components λ1 to λ3, respectively, are arranged on a Y-shape optical waveguide 31 formed on a PLC 30, and each specified voltage V1 to V3 is applied. When input multiplexed light 40 enters the end face 371 of the one optical waveguide 31 of the Y-shape waveguides, the optical waveguide 31 under the electrodes shows changes in the refractive index like diffraction gratings corresponding to the wavelength components by applying specified voltages on the electrodes for the respective wavelength components. Then the wavelength components corresponding to the gratings are reflected and the reflected components exit from the end face 372 of the other optical waveguide 31 of the Y-shape waveguide.

Title: Preparation of printing picture
Inventor: SHIBAZAKI HIROSHI
IPC: G03F3/08
Filed: 1994-09-06
Abstract: PURPOSE: To allocate the appropriate kind of screening by discriminating the application of FM screening or normal screening corresponding to the brightness of color pictures and selecting a screen angle corresponding to a hue. CONSTITUTION: A thinning/increasing processing part 70 thins out the picture data of the pattern of a CMYK display color system read by a scanner 42. A color system conversion part 74 converts the thinned-out picture data to an RGB color system and then, converts them to an HSL color system. An area division processing part 76 performs an area division processing corresponding to the brightness of the pattern and the hue. Thus, a CPU 30 reproduces the area of low lightness by using the FM screening and reproduces the area of high lightness by using the normal screening. Also, the area of the high lightness for which the hue is a warm color system is reproduced while exchanging the screen angle of a C version and an M version.
