In an image processing apparatus, an input image is synthesized with a stored image supplied from a storage unit and having been shifted so that the positions of the pixels in the image areas of the input image and of the stored image, associated with a telop, will coincide. The level distribution of the pixel values of the input image is maintained in the telop.

A fluid compressor includes a piston which has a vertical longitudinal axis. A plurality of working chambers are provided between a cylinder and the piston, and are constituted by upper working chambers and lower working chambers which separated from each other by a center portion of the piston. Fluid is sucked in the lowermost one of the upper working chambers and the uppermost one of the lower working chambers, respectively, and is compressed while being conveyed. The diameter .phi. D3 of a lower shaft portion of the piston and the diameter .phi. D4 of an upper shaft portion of the piston have a relationship .phi. D3

A compressor having a cylinder and a cylindrical rotational body housed within the cylinder. A spiral groove is formed in the outer peripheral surface of the rotational body, and a spiral blade is fitted in the groove so as to be freely retreated in and projected from the groove in the radial direction of the rotational body. The cylinder and the rotational body are rotated relative to each other by a drive mechanism. A fluid to be compressed is introduced into working chambers defined by the blade, the inner peripheral surface of the cylinder and the outer peripheral surface of the rotational body. The fluid is first guided into the first working chamber from a gas suction port, and then into the second and subsequent working chambers successively, whereby the fluid is compressed. An oil supply mechanism supplies pressurized oil to an oil supply hole formed in the rotational body. The oil supply hole communicates with that area of the bottom of the spiral groove, which corresponds to the position where the second and subsequent working chambers begin when the suction stroke of the first working chamber ends. The pressurized oil urges the outer peripheral surface of the blade onto the inner peripheral surface of the cylinder.

A fluid compressor has a sealed case, an electric motor section, and a compression section. Both sections are provided in the sealed case, with their axes extending substantially horizontally. The sealed case is filled with lubricant. At the start of the compressor, the rotational speed N of the electric motor section is gradually increased, but maintained at least once at a prescribed value for a predetermined period. At the stop of the compressor, the rotational speed N is gradually decreased, but maintained at least once at a prescribed value for a predetermined period.
