Granted: 1994-01-18
Abstract: ABSTRACT    A writing device for an optical memory card is disclosed.  In this writing device, tracking correction is performed by moving a mobile objective lens of an optical system in the transverse direction of a track in accordance with a tracking error of the optical system relative to the optical memory card, and the range in which tracking correction can be performed is enlarged by moving a retaining portion of the objective lens by a moving device when first comparison device has determined that tracking error information was outside a predetermined first standard range.  The writing device includes a writing stoppage device for stopping writing data on the optical memory card when a second comparison device has determined that the tracking error information exceeded a second standard range which is wider than the first standard range.  Since the retaining portion of the objective lens is moved in the direction in which any deviation occurring during tracking can be corrected, the range in which tracking correction can be performed can be enlarged.  Further, since it is determined that erroneous tracking is occurring and writing of data is stopped when the deviation occurring during tracking for writing data has exceeded the second standard range which is larger than the first standard range, damage to the written data can be prevented.

Abstract: A scroll type supercharger including first and second orbital spiral elements is disclosed. The supercharger includes a first orbiting scroll having a first orbiting end plate from which a first spiral ele-ment extends, and a second orbiting end plate fixedly attached to said first orbiting end plate, and from which a second spiral element extends. A hollow portion is formed between the first and second orbiting end plates. The housing includes a first casing further includ-ing a first fixed scroll having a first fixed spiral element extending therefrom. The housing also includes a second casing from which a second fixed scroll extends. The first and second casings are fixedly attached to form an operating chamber therein. The orbiting scroll is disposed in the operating chamber such that the orbiting scroll is dis-posed at an angular and radial offset with said fixed scrolls to form at least one pair of sealed off fluid pockets between interfitting pairs of fixed and orbiting spiral elements. The apparatus further includes a drive shaft having a crank pin disposed about its exterior surface.          The longitudinal axis of the crank pin is offset with respect to the longitudinal axis of the drive shaft. The orbiting scroll is supported on the crank pin by bearings. Rotational motion of the drive shaft and the crank pin causes orbital motion of the orbiting scroll. A rota-tional preventing device prevents rotation of the orbiting scroll dur-ing orbital motion thereof. A longitudinal and a radial bore extend through the crank pin, linking central fluid pockets on either side of the orbiting scroll with the hollow portion formed between the first and second orbiting end plates such that the pressure on either side of each orbiting end plate is equalized with the pressure within the outer fluid cavities to prevent bending and warping of the end plates.
