  • Patent number: 6321191
    Abstract: The present invention implements retrieval of mutually related sentences even between sentences in a wide variety of languages. A related sentence retrieval system is provided with n (n is 3 or a greater natural number) cross-lingual retrieval systems for bidirectionally retrieving related sentences between sentences written in language P and sentences written in other languages A to F, a language P sentence input unit is shared by the cross-lingual retrieval systems, and the language P sentence output unit is also shared by them to implement bidirectional retrieval of related sentences via language P between sentences in the other n languages. Thus sentences in language P are handed over back and forth between the cross-lingual retrieval systems to implement bidirectional related sentence retrieval between sentences in n different languages.

  • Patent number: 5349452
    Abstract: A color space of input image information sent from an image input device is recognized, and, if it is not the standard color space, it is judged whether the input image information is associated with color correction data. If the input image information is not on the standard color space but associated with color correction data, it is converted to image information on the standard color space using the associated color correction data. If the input image information is neither on the standard color space nor associated with color correction data, it is converted to image information on the standard color space using color correction data read from a storage device. A conversion device converts the image data on the standard color space to YMCK image information, which is sent to an image output device.

  • Patent number: 4519750
    Abstract: A variable-delivery refrigerant compressor wherein the delivery of a compressed refrigerant is adjustable by an actuator which is movable with a discharge pressure of the compressor between a first position at which plural discharge valves corresponding to compression chambers are rendered operative, and a second position at which at least one of the discharge valves is rendered inoperative. A pilot switch valve is disposed in a passage through which the discharge pressure is applied to the actuator. The switch valve controls a supply of refrigerant of the discharge pressure to the actuator such that the actuator is placed in the first position while a suction pressure of the compressor is relatively high, and in the second position while the suction pressure is relatively low.

  • Patent number: 4252332
    Abstract: A pair of blocks or shell members of an appliance or the like are mated with each other, and an O-ring is fitted in an O-ring groove provided in the mating end surface of one of the shell members along the entire circumference thereof. In addition, a narrow annular clearance space is provided in a mating plane of the mating end surfaces of the shell members on the side close to the outer peripheral surface of the shell members, when assembled, i.e., radially outwards of the O-ring groove, in a manner to communicate with the exterior of the shell members, so that oil trapped in voids defined between an O-ring, and the walls of the O-ring groove and a mating surface of the counterpart shell, after the assembly of the shell members, may be removed with a cleaning liquid with ease. The annular clearance space may be provided either in the mating end surface of one shell member, in which the O-ring groove is formed, or in the mating end surface of the counterpart shell member having no O-ring groove therein.

  • Patent number: 4101249
    Abstract: A swash plate type compressor adapted for use in an automotive cooling system is disclosed. A cylinder block, which forms a principal part of the compressor and is axially divided into two portions, has at least four bores arranged at equal distances along the circumference thereof. A clamping bolt for uniting all principal members of the compressor extends through a hole provided through a narrow interzone lying between each two adjacent bores. The through hole has a diameter considerably greater than that of the clamping bolt. The space between the inner surface of the hole and the outer surface of the bolt serves as a passage through which a low pressure refrigerant gas flows, and this helps simplification in construction and improvement in capacity of the swash plate type compressor.

  • Patent number: 4070136
    Abstract: A multi-piston swash plate type compressor, in which there is provided an improved internal arrangement for lubricating internal moving elements, especially steel ball bearings and shoes connecting the swash plate and the multi-pistons. The improved internal arrangement for lubricating the steel ball bearings and shoes comprises providing means for directly introducing a part of said oil particles suspended in the refrigerant gas which rushes into the combined block from the exterior of the compressor through one or more inlet ports formed in the combined block, into a swash plate chamber for rotatably mounting the swash plate therein, whereby the oil particles lubricate said ball bearings and shoes during operation of the compressor. The improved internal arrangement further contributes to effective employment of the blow-by refrigerant gas for distribution of oil lubricant to the cylinder bores along with said internal moving elements.
