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： In the screw compressing apparatus, by rotating paired male and female rotors as meshing with each other, a gas is suctioned from a suction chamber into a working space, and compressed in the working space. The compressed high pressure gas is exhausted from a exhaust chamber, and then cooled by an aftercooler, thereby producing a low temperature, high pressure gas. In the compression process, the temperature of the gas in the working space becomes high at the exhaust chamber side. When this exhaust gas temperature reaches a predetermined value, a part of the gas cooled by an aftercooler is injected into the working space for lowering the temperture in the working space.

摘要： A dual-charging system for a portable electric appliance such as a video camera comprises a rechargeable battery pack having a built-in charge circuit and a separate charger unit. The battery pack is capable of selectively taking a first charging operation with the use of the built-in charge circuit and a second charging operation with the use of a charge circuit of the charger unit. The charge circuit of the charger unit is designed such that a charging rate of the battery pack by the second charging operation is faster than that by the first charging operation. Therefore, when a rapid charging of the battery pack is desired, it is preferred to select the second charging operation. On the other hand, when the electric appliance is used, for example, during a journey, it is preferred to select the first charging operation because the charger unit is inconvenient to carry during a journey.

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： 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.
