Abstract: Refrigerant compressed by a first stage compression elements (30) run by a motor (20) is discharged in the closed container (10) via a silencer chamber (35) to cool the motor (20) before the refrigerant is led to a second stage compression element (40). The refrigerant is discharged from the second stage compression element (40) out of the compressor after it is further compressed in the second compression element (40). Thus, the motor (20) is cooled in a simple cooling mechanism during normal operation of the compressor.

Abstract: In case of reading an original of plural pages and collectively transmitting the successive short length pages as one page, the number of transmitted pages recorded on a transmission record list becomes different from the number of read pages, so that it is difficult for a user to judge, from such list, whether all the pages have been transmitted. In case the number of actually transmitted pages is different from the number of read or received pages stored in the second RAM, the user can select in advance, by a key depression on a keyboard, whether to record both the number of actually transmitted pages and the number of read or received pages stored in the second RAM or to record either one of the numbers, as the number of pages to be recorded on the transmission result list.

Abstract: It is an object of the invention to improve wear resistance and an anti-seizure property of a portion , on which a radial load operates owing to tension of a cogged belt or a V-belt, of a plain bearing for an engine. A main shaft portion of a crankshaft is in uneven contact with an upper half bearing owning to tension of the cogged belt and/or the V-belt. A branch groove is formed in a portion forwarder than an oil groove formed on the bearing surface of a upper half bearing of a plain bearing, the branch groove branching off from the oil groove. When an engine stops, lubricant is stored within the branch grooves, and when the engine restarts, the lubricant within the branch grooves is immediately supplied to the uneven contact portion of the main shaft portion though the rotation thereof.

Abstract: A hologram 48 as optical path branching element has two hologram areas 48b and 48c for diffracting a return light beam into different directions, and a boundary 48a between them is inclined at a predetermined angle with respect to the direction corresponding to the direction of radius of the optical disc 11. The light diffracted by the one hologram area 48b is received by light-receiving sections A1 and A2 of a photodetector IC 44, and the light diffracted by the other hologram area 48c is received by light-receiving sections A3 and A4. With the above-described structure, a position deviation of an objective lens 27 at the time of access to a desired recording track on an optical disc 11 can be detected by finding the difference between the light quantity of the light received by the light-receiving sections A1 and A2 of the photodetector IC 44 and the light quantity of the light received by the light-receiving sections A3 and A4.
