摘要： An optical reproduction apparatus in accordance with the present invention has a gain control circuit for controlling a gain of an amplifier circuit which amplifies a reproduction signal in accordance with amplitudes of the reproduction signal from an optical recording medium. The amplitude is sent to a power control calculation circuit which controls the reproduction power of a light beam in accordance with the amplitude. The gain control circuit has a slower response speed than that of the power control circuit at least during a period when the power control circuit controls the reproduction power. This allows to provide an optical reproduction apparatus that can realize the stable reproduction power and automatic gain control even to the unevenness of the amplitudes of the reproduction signal.

摘要： A taking lens of a camera includes first and second lens elements. A lens holding frame retains the first lens element on a lens base or a front surface of a shutter unit. In the lens holding frame, a holding frame body is disposed in front of the first lens element. Arm portions are formed to project from a periphery of the holding frame body, have a distance to the lens base when in a free state, are bent resiliently by a retention pin or screws, and are secured to the lens base. Thus, the first lens element is squeezed tightly between the lens base and the holding frame body.

摘要： A magneto-optical disk reproducing device includes a clock producing circuit, which, on the basis of a reproducing signal from recorded marks recorded in a magneto-optical disk, produces a timing offset from peak positions of the reproducing signal; an A/D converter, which samples the reproducing signal in accordance with the timing, and outputs a reproducing signal quantity; and a short mark signal quantity averaging circuit and a long mark signal quantity averaging circuit, each of which averages a plurality of reproducing signal quantities. When projecting a light beam onto a magneto-optical disk, the magneto-optical disk reproducing device controls light quantity of the light beam on the basis of a ratio between the respective values outputted by the foregoing averaging circuits. By this means, the A/D converter is able to sample the reproducing signal at more timings than when a reproducing signal is detected at peak positions thereof, and the magneto-optical disk reproducing device can detect the foregoing ratio more precisely. Consequently, the magneto-optical disk can control the light quantity of the light beam more accurately.

摘要： It is an object of the present invention to provide a hollow fiber forward osmosis membrane, which can enhance forward osmotic pressure energy acquired by permeation, and thus improve power generation efficiency in the forward osmotic pressure power generation, when dilution water such as freshwater permeates into seawater through the osmosis membrane. The relationship between optimal conditions for an inner diameter d and a length L of the hollow fiber osmosis membrane to be used for forward osmotic pressure power generation whereby dilution water such as fresh water is caused to permeate into non-concentrate seawater through the hollow fiber osmosis membrane to increase a flow rate on the side of the seawater using forward osmotic pressure energy thus generated, and power is generated using the increased flow rate, is expressed as equation (1) in the range of d=50 to 200 μm, L=0.5 to 2 m and J=1.7×10−7 to 5.1×10−7 m/sec,[Equation 11] d L 0.75 + J 0.5 = 1.0 × 10 5 ∼ 1.2 × 10 5 wherein J means permeation flux rate.

摘要： An optical information recording medium (1) includes, on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a cover layer (10) provided in a position farthest from the substrate (50). The RE layer (40) is an information recording layer provided in a position farthest from the light transmitting layer and also is a recording layer of disc type identification information and an individual identification number recorded in a format allowing easier determination as compared to an information recording format used in the layer allowing only readout of information by use of light irradiation.Therefore, it becomes easy to check a disc type in a recording/reproducing device and one recording/reproducing device can be shared with other types of optical disks. Further, disk production becomes easy. In addition, it becomes possible to obtain an optical information recording medium that makes it possible to replace outdated data in the ROM layer by recording, in the RE layer, updated data obtained at the time when net connection can be established.
