Abstract: PURPOSE: To solve a problem that the efficiency of laser light having a wavelength λ1 is lowered when a diffraction grating 1a for the laser light of λ1 is designed while depending on laser light having a wavelength λ2 or efficiency of the laser light of λ 2 is lowered conversely when a diffraction grating 1b for laser light of λ2 is designed while depending on the laser light of the wavelength λ1 in a conventional optical member. CONSTITUTION: The diffraction gratings 1a and 1b are formed so that projecting parts 1a1 and 1b1 and recessed parts 1a2 and 1b2 can be respectively alternately formed on the surfaces thereof and the width dimension of the projecting parts 1a1 and 1b1 can be different from that of the recessed parts 1a2 and 1b2. While defining projecting part width/(projecting part width + recessed part width) as a DUTY ratio, the optical member is designed while changing this DUTY ratio. Thus, design is enabled while changing efficiency in the 0th-order diffracted light and 1st-order diffracted light of laser beams.

Abstract: PURPOSE: A compact television set is provided to allow a user to freely watch television broadcasting in any place where a docking part is set. CONSTITUTION: A compact television set includes a docking part(100) having a signal input unit(10) for receiving signals from an antenna, a video line, an s-video line, a DVD line, a DTV line, a PC line and an AC power lines, and a moving part(200) having a display panel(20), a signal processor(30), a speaker(40) and a power supply(50). The docking part and moving part are detachably combined with each other. The signal processor includes a tuner(31) for tuning a signal inputted through the antenna, a video processor(32) for processing the tuned signal, an A/D converter(33) for processing signals inputted from the DVD, DTV and PC lines, a scaler IC(34) for scaling the signals of the video processor and A/D converter under the control of a microcomputer(35) to display the signals on the display panel, and a sound IC(36) for converting signals sent from the video, DVD, DTV and PC lines into sound signals to output the sound signals through the speaker.
