    摘要： The present invention reduces the capacity of the AC-DC converter for the peak load and realizes low price and reduction in the volume of the power unit. The apparatus built-in backup power supply has the peak cut function for sharing a part of the load current at the time of peak load from the secondary battery. The two-way DC-DC converter 5 and the secondary battery 4 are installed on the DC output side of the AC-DC converter 3 and a current larger than a predetermined peak cut level is discharged from the secondary battery 4 at the time of peak load. Further, when the load is less than the predetermined cut level, the secondary battery 4 is charged from the AC-DC converter 3 via the two-way DC-DC converter 5. Furthermore, a most suitable peak cut level according to the SOC of the secondary battery and load pattern is automatically set and dynamically changed.

    摘要： Apparatus built-in backup power supply system has a “peak cut” function for sharing a part of the load current at the time of a peak load using a secondary battery. For this purpose, a two-way DC—DC converter 5 and the secondary battery 4 are installed on the DC output side of the AC-DC converter 3, and that portion of the load current that exceeds a predetermined peak cut level is discharged from the secondary battery 4 during peak loading. When the load is less than the predetermined cut level, the secondary battery 4 is charged from the AC-DC converter 3 via the two-way DC—DC converter 5. A suitable peak cut level is determined according to the state of charge of the secondary battery and load pattern, and is changed dynamically.

    摘要： An optical apparatus comprises an optical device having an optically functional material sandwiched between a pair of substrates with electrodes formed on opposing surfaces. The optically functional material has such a characteristic that intensity of light issuing from the optical device changes asymmetrically in response to inversion of the polarity of an applied external field. Pulse voltages of one polarity for determining the intensity of the issuing light and pulse voltages of an opposite polarity are applied from a source at a predetermined period so that an average voltage is zeroed within the predetermied period. The issuing light intensity under the application of the pulse voltages of one polarity and the issuing light intensity under the application of the other pulse voltages are selected or changed by a switching unit.

    摘要： A driving method for an optical printer and an optical printer having a liquid-crystal light switching element including a ferroelectric liquid crystal sandwiched between a pair of plates provided with electrodes on adjacent surfaces thereof. The liquid-crystal light switching element is disposed between a light source and a movable photosensitive surface and controlled so as to at least one of transmit and block light from the light source to the photosensitive surface for enabling a printing operation. Voltages v.sub.1 and v.sub.2 are applied to the liquid-crystal switching element substantially in accordance with the equation ##EQU1## and the intensity of light from the light source incident on the liquid-crystal switching element is controlled so that incident light intensity during a period T.sub.2 is weaker than the incident light intensity during a period T.sub.1, where t.sub.0, t.sub.1, t.sub.2 and t.sub.3 represents times, T.sub.1 (=t.sub.1 -t.sub.0) is the period during which a printing operation is effected, T.sub.2 (=t.sub.3 -t.sub.2) is the period during which the photosensitive surface moves, v.sub.1 is the voltage which is applied to the liquid-crystal switching element during the period T.sub.1, and v.sub.2 is the voltage which is applied to the liquid-crystal switching element during the period T.sub.2.
