    摘要: A light-emitting device includes a light-emitting element emitting primary light and a wavelength conversion portion absorbing a part of the primary light and emitting secondary light having a wavelength equal to or longer than the wavelength of the primary light. The wavelength conversion portion includes a plurality of green or yellow light-emitting phosphors and a plurality of red light-emitting phosphors. The green or yellow light-emitting phosphor is implemented by at least one selected from a specific europium (II)-activated silicate phosphor (A-1) and a specific cerium (III)-activated silicate phosphor (A-2). The red light-emitting phosphor is implemented by a specific europium (II)-activated nitride phosphor (B). The light-emitting device emitting white light at efficiency and color rendering property higher than in a conventional example can thus be provided.

    摘要: In a signal detection circuit for an optical disk, a comparator converts an analog HF signal into a digital HF signal by using a slice level. A dropout detection circuit detects a dropout of the digital HF signal. A charge-pump circuit feeds back a slice-level control voltage to the comparator based on a result of the detection by the dropout detection circuit. A voltage follower holds and outputs a voltage stored in the capacitor. A switch is turned OFF when a dropout signal has been detected, and outputs to the voltage follower the voltage that has been stored in the capacitor during an ON state of the switch. A second switch is turned ON when a dropout signal has been detected, and applies an output of the voltage follower to the comparator.

    摘要: A light emitting element array has light emitting elements disposed on a base plate in an array and a rod-like converging lens is disposed adjacent and parallel to this array. The end surfaces of this rod-like lens are curved, or otherwise so shaped that light beams from the array are refracted towards the center of the lens, thereby increasing the relative distance on a target surface that can be effectively irradiated.
