    摘要: An optical wavelength conversion device is composed of an organic nonlinear optical material, and a cladding layer having a refractive index lower than the refractive index of the organic nonlinear optical material and covering the organic nonlinear optical material, thereby to convert a fundamental wave entering the optical wavelength conversion device to a second harmonic, and to radiate the second harmonic. At least one of device edge faces including edge faces of the organic nonlinear optical material is provided with a shielding layer for shielding the device edge face from ambient atmosphere, thereby to prevent the organic nonlinear optical material from sublimation and deterioration.

    摘要: The title of a program with a recording duration longest among all recording durations is recorded as the program title of a relevant program file. Thereby, even when a user has performed an operation to record a program on a hard disk recorder by a method other than a timer recording, the program title of a program that is most likely to be a program a user really desires to record can be recorded as the program title of a program file created by the recording. Accordingly, a DTV or a STB can display on its display appropriate program titles in a program file list at the time of playback of a previously recorded program.
