    摘要: A liquid crystal display device includes a video RAM for storing character and graphic data, a control circuit for selecting specific data from the RAM to be displayed on a liquid crystal display panel, and a positive/negative mode selector for selecting one of a positive display mode in which data is displayed as lighted elements against a dark background, and a negative display mode in which data is displayed as dark elements against a lighted background. The display device allows the use of software developed for CRT based data processors to be run in LCD mounted data processors in which the data formats would otherwise be reversed.

    摘要: An oil-cooled type screw rotor assembly having a female rotor and a male rotor adapted to rotate around parallel axes in meshing relation to each other. The leading side flank of the female rotor is constituted by a first leading side flank formed by an arc of a radius R.sub.1 and a second leading side flank formed by an arc of a radius R.sub.2. Also, the trailing side flank of the female rotor is constituted by a first trailing side flank formed by an arc of the tooth ends of the male rotor having a radius R.sub.5 and a second trailing side flank formed by an arc of a radius R.sub.3 which is smaller than the radius R.sub.2 of the second leading side flank. The configuration of the teeth of the male rotor is materially formed by arcs of the leading and trailing side flanks of the female rotor.

    摘要: A screw compressor including a scavenging port, which is separate from a discharge port, located on or in a vicinity of a discharge-side end face of the working space of the casing, for scavenging gas therethrough from a compression chamber near to a completion of a suction stroke. Gas of high temperature leaking from a compression chamber on high-pressure side into a compression chamber on a low-pressure side (in the suction stroke) can be scavenged from the compressor to outside, thereby avoiding a reduction in suction volume efficiency, an increase in consumption of power, and a rise in temperature of gas to be compressed which might otherwise be caused by the gas of high temperature leaking into the compression chambers during a suction stroke.

    摘要: A screw compressor including a female rotor and a male rotor rotating while meshing with each other, with the rotor tooth form of one of the female and male rotors meshing with each other without any clearance therebetween in normal temperature condition being used as a basic tooth form for obtaining a rotor tooth form produced by deformation on account of thermal expansion during operation. The basic tooth form and the tooth form thus obtained are employed in the assembled compressor. The rotors with these teeth form, when brought together in meshing engagement, have a clearance at start-up which allows for their expansion. This clearance is maintained at a minimum during operation of the compressor.

    摘要: A screw compressor having a recess formed in the high-pressure end surface of the casing. This recess receives the fluid from a closed working space which has just been isolated from the discharge port and closed in the compression step. Consequently, the abnormal pressure rise in the closed working space, which is caused due to the compression of the fluid confined, is completely eliminated. The recess has a configuration involving a curve conforming with the leading flank of the female rotor at the instant at which the working space is isolated from the discharge port and closed.
