    摘要: A data output portion transmits a pulse signal having a pulse width according to a value of transmit data on a predetermined cycle. An H pulse width counter and an L pulse width counter measure a length of a high level period and a length of a low level period in the received pulse signal by using a clock signal having the same frequency as that of the clock signal used in the data output portion. A comparing portion compares the sum of both the measured lengths of the periods with the predetermined cycle, and outputs an error signal in case of a mismatch. In a PWM communication system, it is also possible to detect a signal delay or an error of the clock signal, which is temporarily caused within one cycle.

    摘要: The electrophotgraphic photoreceptor is composed of an electrically conductive substrate having formed thereon a photosensitive layer containing a phthalocyanine mixed crystal comprising titanyl phthalocyanine and hydrogen phthalocyanine, wherein the phthalocyanine mixed crystal has peaks at 6.8.degree., 7.4.degree., 15.0.degree., 24.7.degree., 26.2.degree., and 27.2.degree. of the Bragg angle (2 .theta..+-.0.2.degree.) in the X-ray diffraction spectrum and having a ratio of the peak intensity at 27.2.degree. to the peak intensity at 6.8.degree. of 1 or more. The electrophotographic photoreceptor can output the output signals as digital signals even when the input light is a digital light or an analog light and thus the electrophotographic photoreceptor can be used for an electrophotograph of a digital recording system and even when the photorecetor is used as a conventional photoreceptor for PPC (analog light input), high-quality images having sharp edges can be obtained.

    摘要: A zoom lens barrel based on the vari-focal optical system includes a zoom cam ring which is supported only rotatably about the optical axis and a focus cam ring which is supported movably only in the axial direction both fitted on a fixed tube inside a lens barrel. For the alteration of the lens focal length, the zoom cam ring is turned to carry out zooming, and for the focusing of an object, the focus cam ring is moved in the axial direction to carry out focusing, thereby preventing the interference between zooming and focusing caused by the movement of the lens sets. A drive mechanism based on a piezo-electric element is used to move the focus cam ring in the axial direction, thereby simplifying the structure and reducing the weight.

    摘要: A scroll-type compressor having a unique coupling arrangement for driving the movable scroll is provided. The side of the base portion of the movable scroll opposite the spirals has a plurality of recesses disposed in a circular pattern. A support plate having a plurality of complementary recesses therein is positioned such that its recesses face the recesses in the movable plate. The diameters of the first and second recesses are different from one another. Coupling members are disposed between each facing pair of recesses. The coupling member has small and large diameter portions. The small diameter portion extends into its associated smaller recess while the large diameter portion extends into its larger associated recess. With this arrangement, the required width of the recess bearing portion of the support plate may be reduced relative to conventional designs which has several advantages.
