A hydrogen compressor system comprises a hydrogen generating apparatus for generating hydrogen gas to be supplied to a fuel cell vehicle and a multi-stage reciprocating compressor for pressurizing the hydrogen gas generated by the hydrogen generating apparatus. High pressure tanks having maximum use pressure of 20 MPa are connected to middle stages of the multi-stage reciprocating compressor by gas supplying lines via valves. By opening/closing the valves, hydrogen gas in the high pressure tanks can be selectively supplied to the middle stages of the multi-stage reciprocating compressor.

A reciprocating compressor includes: a low-pressure stage compression part for compressing low-pressure working gas supplied from a supply source; two high-pressure stage compression parts for compressing the working gas compressed by the low-pressure stage compression part at two stages; and a crank mechanism for driving the low-pressure stage compression part and the high-pressure stage compression parts. The two high-pressure stage compression parts each have a plunger and a cylinder and are arranged on both sides of the crank mechanism in such a way as to extend coaxially opposite to each other. The low-pressure stage compression part has a piston and a cylinder and is located in the middle of the two high-pressure stage compression parts. The crank mechanism, the low-pressure stage compression part, and the two high-pressure stage compression parts are substantially located in the same plane.

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.

A disk apparatus in which the thickness is suppressed. A recording/reproducing medium containing a disk rotatably in a hard case is moved substantially in a horizontal direction through an opening of the base of the disk apparatus for insertion and ejection operations of the recording/reproducing medium and recording/reproducing operation. For this purpose, the following are provided: a recording/reproducing unit for performing recording and reproduction, a container for containing the recording/reproducing medium at a predetermined position in the disk apparatus when the disk is inserted, a rotation motor for giving a predetermined turning effort by performing the chucking to the recording/reproducing medium, a chucking position where the chucking is performed, a vertical movement mechanism for moving the rotation motor to the waiting position where the recording/reproducing medium is inserted or ejected, a control mechanism for retaining the vertical movement mechanism to the chucking position, and a release mechanism for releasing and ejecting the recording/reproducing medium.

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.
