    摘要: A sensor circuit for telephone line includes a line current detecting circuit (52, 54) which generates a detection signal in response to a line current flowing in a telephone line (20, 22). The detection signal is applied to a first amplifier (56), and the detection signal as amplified is not only further amplified by a second amplifier (57) but also applied to a tone deriving circuit (60) and a CI detecting circuit (61) via a coupling capacitor (59). The detection signal as amplified twice is applied to a comparing circuit (58) which compares the detection signal from the second amplifier with a first reference voltage (V1) and a second reference voltage (V2), so that a line current supervisory signal is outputted from the comparing circuit. The tone deriving circuit includes a band-pass filter and derives a tone signal from the detection signal from the first amplifier. The CI detecting circuit detects a CI (calling tone) on the basis of the detection signal from the first amplifier.

    摘要: A reciprocating compressor has a plurality of compressor stages each compressing a working gas by combining a cylinder and a plunger, and its discharge pressure exceeds 40 MPa. The compressor stage has a packing seal which seals a shaft of the plunger, and oil pouring means which pours a lubricating oil to the packing seal. A filter removes the lubricating oil poured by the oil pouring means from the working gas. In the filter, a first element using micro glass fiber and a second element using functional activated carbon are coaxially mounted. These two elements are included together in a pressure container. According to the above described construction, in the compressor at a high pressure exceeding 40 MPa, quality of the discharge gas can be kept and the compressor can be made compact.

    摘要: A focusing and tracking servo system for generating focusing and tracking error signals for use in driving a servo system which focuses and tracks an optical beam, such as a laser beam on an optical disk. The system includes a photosensor having two sub-photosensors arranged to be adjacent to each other and to have a common boundary, and the laser beam has a circular cross-section and an optical axis. The laser beam reflected by the optical disk is incident on the photosensor so that the optical axis is offset from the boundary between the sub-photosensors. Consequently, the optical spot formed on each sub-photosensor has a different area and the sub-photosensors generate different photoelectric currents. The output currents from the sub-photosensors are individually amplified by amplifiers having adjustable amplification factors, and the amplification factors are set so that they are inversely proportional to the output current of the sub-photosensors when the laser beam incident on the optical disk is in an in-focus state. When the laser beam incident on the optical disk is in an out-of-focus state the optical spot changes, and thus the relative output currents of the sub-photosensors change. A focusing error signal is generated in accordance with the difference of the output currents of the amplifiers. In another embodiment of the present invention a photosensor array having four sub-photosensors arranged in a quadrant matrix with two boundaries is utilized to generate both focusing and tracking error signals.

    摘要: An image processing apparatus includes an edge-portion detector, an edge-width detector, and a tone correction unit. The edge-portion detector detects a pixel of an edge portion by determining whether or not each of pixels constituting image data which has been input is a pixel which is included in the edge portion. The edge-width detector detects, for the pixel of the edge portion detected by the edge-portion detector, an edge width which is a width of the edge portion. When the edge width detected by the edge-width detector is smaller than a value which is set in advance, the tone correction unit performs tone correction differently in accordance with the detected edge width.
