摘要： An optical disk apparatus includes a semiconductor laser for emitting a light beam, and an automatic power control or APC circuit for driving the laser. A compound prism structure is optically coupled to the laser in an optical head section, and defines a first optical path for causing a front laser light to be projected onto a rotating optical disk and guiding a reflected light therefrom toward a first photodetector, and a second optical path for guiding a part of the reflected light toward a second photodetector. An output signal of the first photodetector is used to generate a reproduced information signal. An output signal of the second photodetector is fed back to the APC circuit as a front light monitor signal. A part of a laser control signal internally generated in the APC circuit is supplied through a wiring line to a noise reduction circuit as a laser noise monitor signal. The noise reduction circuit subtracts this noise monitor signal from the reproduced information signal to provide a noise-suppressed information signal.

摘要： An optical head device adapted to be optically coupled to an optical disk includes a light-source laser and an objective lens optically coupled thereto. This lens receives an output light of the light source, and causes it to be projected onto the optical disk to form a focused spot thereon. Photodetectors which are arranged near the light-source laser are optically coupled to the lens in one optical path so that they are responsive to a light component which is reflected from the optical disk toward the photodetectors by way of the objective lens. A beam-shaping prism is located between the lens and a group of the light source and the photodetectors in the optical path. When the laser output light travels toward the lens, the prism reshapes the light into a predetermined isotropic beam profile. When the reflected light from the optical disk propagates reversely along the same optical path to enter the beam-shaping prism, this prism permits such an incident light to pass through itself toward the photodetectors.

摘要： A chemical vapor deposition apparatus has a vacuum processing chamber, a susceptor for holding a plurality of substrates each placed with a film deposition surface thereof facing downward; a heater disposed above the susceptor; a first barrier gas supply port for supplying a barrier gas to the upper surface of the susceptor; and a second barrier gas supply port for supplying the barrier gas to the upper surface of the heater. The barrier gas supplied from the first barrier gas supply port and the barrier gas supplied from the second barrier gas supply port have their flow rates controlled independently. By properly setting the ratio between the amount of the barrier gas supplied from the first barrier gas supply port and the amount of the barrier gas supplied from the second barrier gas supply port and the ratio between the amount of the barrier gas supplied and the amount of a raw material gas supplied, it becomes possible to form a film which is reduced in the number of particles adhered thereto.
