摘要： A fluid compressor comprises a cylinder and a columnar rotating body synchronously rotated by a drive means, The rotational movement of the cylinder and the columnar rotating body is supported by a pair of roller bearing assemblies. A clearance is provided between the roller bearing assemblies and bearing members to allow fluid from the compression chambers to pass into an interior of the casing of the compressor. With the arrangement of roller bearing assemblies at the ends of cylinder and columnar rotational body combinations, a large diameter of the cylinder is possible and thus high compression efficiency of the fluid compressor is achieved.

摘要： A fluid compressor has a piston, the axis of which is vertical. The dimensions of the parts of the compressor are determined such that an upward thrust force acting on the piston is substantially equal to or slightly greater than the total weight of rotational parts including the piston and a cylinder. Specifically, a groove formed in the piston has a pitch decreasing gradually from a lower part to an upper part of the piston, and a diameter (.PHI.D1) of a lower shaft portion of the piston, a diameter (.PHI.D2) of a upper shaft portion of the piston, and an inside diameter (.PHI.Dc) of the cylinder have a relationship, (D1.sup.2 +D2.sup.2)>Dc.sup.2.

摘要： An image reading apparatus comprises a correcting mechanism for correcting an output signal from a reading unit in accordance with a reference level. The correcting mechanism includes a reference element for setting the reference level and a drive mechanism for rocking the reference element between a first position in which the reference element is advanced to a reading position and a second position in which the reference element is retreated from the reading position. The drive mechanism includes a rotating member that is continuously rotated in one direction. As the rotating member rotates, the reference element rocks between the first and second positions, thereby executing correction of the output signal before image information recorded on a recording medium is read.
