    Abstract: A multi-beam scanning device is provided with a light source that emits a plurality of light beams, a polygonal mirror that deflects the light beams emitted by the light source to scan, and an optical system that converges the deflected light beams on a plurality of objects to be scanned. The optical system includes an optical path turning system that turns optical paths of the deflected light beams, respectively. The optical path turning system is constructed such that optical path lengths of the optical path of the deflected light beams are the same, and one of the optical paths directed to an object located farthest from the polygonal mirror consists of two linear paths and one turning portion at which a beam is deflected.

    Abstract: A multi-beam scanning optical system is provided with a light source unit emitting a plurality of beams. The beams are incident on a polygonal mirror, and deflected thereby to scan in a predetermined scanning range. The scanning beam is incident an f&thgr; lens system. The f&thgr; lens system includes a plurality of lenses, and all the beams pass at least one of the plurality of lenses included in the f&thgr; lens system. The lens, which all the beams pass through, is formed as a single lens element made of single material. Further, the lens contributes to convergence of the beams in the main scanning direction.

    Abstract: An antiferroelectric liquid crystal cell having a high-speed response and wide viewing angle characteristic free of an image sticking phenomenon is provided. This antiferroelectric liquid crystal cell is composed of an antiferroelectric liquid crystal material held between a pair of parallel substrates. The antiferroelectric liquid crystal material filled between the parallel substrates has such a characteristic that when a sinusoidal voltage value with a changing reference frequency is applied to the antiferroelectric liquid crystal cell, the imaginary part of the complex dielectric constant obtained by Fourier transform of the output voltage value output from the antiferroelectric liquid crystal cell has no local maximum value within the reference frequency range of 100 Hz to 5 kHz. In other words, this characteristic is similar to a characteristic such that when the real part and the imaginary part of the complex dielectric constant are plotted by using a Cole--Cole plot for each frequency, a characteristic curve having no local maximum value within the reference frequency range of 100 Hz to 5 kHz is obtained.

    Abstract: A scroll type compressor including mutually mating stationary and movable scrolls for producing compression. A circumferentially outer part of the movable scroll portion has a flat end surface and a chamferred surface. The chamferred surface tapers outwardly at an angle relative to the flat end surface greater than an allowable tilt angle of the movable scroll. A circumferentially inner part of the scroll portion includes a flat end surface only which has a groove to receive a tip seal, the tip seal having a height greater than a depth of the groove. The circumferentially outer part has an identical outer diameter to that of the base plate portion, and the base plate portion and the scroll portion are simultaneously machined.
