    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： 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 fixing device includes a fixing rotator, a heat source, a controller, a pressure rotator, and a nip formation pad. The controller controls the heat source such that a temperature of the fixing rotator is equal to a preset fixing temperature. The nip formation pad abuts the pressure rotator via the fixing rotator and forms a nip between the fixing rotator and the pressure rotator. When a print time of a previous job is longer than a prescribed time A and a next job is started within a prescribed time B after an end of the previous job, the controller corrects the preset fixing temperature during a time from a start of the next job to an entry of a print sheet into the nip and during a time from the entry of the print sheet into the nip to a lapse of a prescribed time C after the entry.
