Abstract: In a phase locked loop composed of digital circuits, the circuit scale of a circuit that generates phase difference information is reduced. A multi-phase clock generation circuit generates a plurality of feedback clock signals having different phases. A feedback side frequency divider divides frequencies of the plurality of feedback clock signals and outputs the feedback clock signals as frequency-divided clock signals. A reference clock latch circuit holds the frequency-divided clock signals in synchronization with a reference clock signal and outputs a held value. A control circuit controls the frequencies of the plurality of feedback clock signals on the basis of the held value.

Abstract: The use time till a display unit including an hour meter (a time measuring device) is replaced can be continued even if the time measuring device fails, and false alteration after shipping can be prevented while infallibly resetting the hour meter to zero when the vehicle equipped with the hour meter is shipped from the factory. The cargo handling vehicle includes a first storage device for accumulatively storing the vehicle use time measured by a first time measuring device provided in a display unit of the vehicle and a second storage device for accumulatively storing the vehicle use time measured by a second time measuring device provided in a control device. The control device allows the first and second storage devices to communicate the accumulated use times stored therein when the electric power of the vehicle is turned on. The control device compares the accumulated use times and writes the longer accumulated use time in the storage device storing the shorter one.

Abstract: A laser driving device includes a storage unit that stores signal patterns for recording-waveform control representing level information of each divided driving signal to drive a laser device on a space and a mark based on the divided driving signals. Also, it includes a pulse generator that generates the reference pulse and the switching pulse based on a first transmission signal and a second transmission signal. The first transmission signal contains timing information for acquiring a reference pulse that represents a timing of repetitively switching between the space and the mark. The second transmission signal contains timing information for acquiring a switch pulse that represents a timing of switching the signals. Among level information for each of the signals in the storage, reference level information is read together with the reference pulse. Other level information after the reference level information is sequentially read for each switching pulse.
