  • Patent number: 7460249
    Abstract: A measuring instrument of polygon mirror motors includes a first light source, a first photo detecting element for detecting a first reflected light beam, i.e. first measuring light beam emitted from the first light source and reflected from the polygon mirror, a second light source, a second photo detecting element for detecting a second reflected light beam, i.e. second measuring light beam emitted from the second light source and reflected from the polygon mirror; and a calculator for performing a calculation based on a time difference between an output from the first photo detecting element and an output from the second photo detecting element. The calculator outputs at least one of an eccentricity and a level difference between facets of the polygon mirror.

  • Publication number: 20080198527
    Abstract: In a surge protection device 40 (40-1 or 40-2) used for a surge protection apparatus, a gas arrester 41 is connected in series with a varister group consisting of a plurality of varisters 42-1 to 42-5 which have high withstand capacity and are connected in parallel to one another and a discharge resistor 43 is connected between both electrodes of the varister group. Besides, since the varister voltages are set higher than the peak value of the AC power supply voltage, the varisters 42-1 to 42-5 are normally insulated from a power supply circuit by the gas arrester 41. Even if an abnormal voltage is applied, since an operating voltage of the varisters 42-1 to 42-5 is set higher than a peak value of the AC power supply voltage, AC power supply current will not flow. Charges stored in the varisters 42-1 to 42-5 are released quickly through the resistor 43, making it possible to prevent the gas arrester 41 from restriking.
