    摘要： A radio receiver includes a first sampling section and a second sampling section for sampling, in the predetermined sampling interval, a first receiving symbol and a second receiving symbol transmitted to the radio receiver via a first transmission route and a second transmission route, respectively. The radio receiver further includes a diversity combining section for diversity combining sampling signals obtained by the respective sampling, sections and a control section for controlling a sampling position to obtain the difference between the sampling position of the first receiving symbol sampled by the first sampling section and the sampling position of the second receiving symbol sampled by the second sampling section such that the obtained difference is different from the difference in the sampling positions corresponding to the difference in timing between the first receiving symbol and the second receiving symbol.

    摘要： A checking method for a device having a plurality of light emitting elements, especially an LED array installed in electronic printing equipment. The check is done while the LED array is mounted in the equipment and does not require removal thereof. The check is done in a short time period, so it can be done during a period of page change of the printer, without disturbing the operation of the printer. Each of the LEDs are lighted one by one with a pulse. The output emission of the array is detected by a photoelectric detector which is positioned to detect the emission from any of the LEDs. The output of the detector becomes a burst of pulses, each of the pulses representing the emission property of a corresponding LED. Each pulse is converted into a digital signal and stored in a RAM as emission data. The emission data is fed back to the driver of each LED to compensate for differences in the emission characteristics of the LEDs. This improves the uniformity of the output image the electronic printer. Each time of the check is performed, the RAM is rewritten. Thereby, a change in the emission data indicates a change or degradation of one or more of the LEDs. This enables one to forecast the life expectancy of the LED array, and maintenance of the printer becomes easier.
