    摘要： A method of correcting a dead time in an analog/digital converter or a linear amplifier in which a time, which is obtained by adding a time, from a predetermined level to a peak of an output generated by a slow amplifier after an input of a pulse signal from a first amplifier, to a time required for treating an output signal from said slow amplifier, is used as a dead time to reduce a correcting error.

    摘要： An analog/digital converter includes a peak holding circuit for holding a peak voltage of input analog data and a peak time detecting circuit for detecting a point of time when the input analog data reaches a peak voltage. Also included is a constant current discharging circuit for discharging the peak voltage held in the peak holding circuit at a constant current from the peak point of time detected by the peak time detecting circuit. The converter also includes a zero time detecting circuit for detecting a zero point of time when a voltage held in the peak holding circuit is reduced to zero and a time to digital converting circuit for counting a number of pulses in a pulse line obtained by gating clock pulses during a period of time from the peak time detected by the peak detecting circuit to the zero time detected by the zero time detecting circuit, the time to digital converting including a counter to output digital data corresponding to the input analog data. A positive offset analog voltage is added to the input analog data and a digital compensator compensates the digital data obtained by the time to digital converting circuit by providing a negative offset digital value approximately corresponding to the positive offset analog voltage, more correctly, equal to a number of pulses in a pulse line passing through a clock gate of the time-to-digital converting circuit for a period of time during which the input analog data has a value equal to zero.

    摘要： An electrostatic spray device and a cartridge for an electrostatic spray device that reduce the occurrence of electrically induced emulsion product separation are disclosed. The device and/or the cartridge may reduce electrically induced emulsion product separation by providing a conductive high voltage shield substantially around the product reservoir. Alternatively, the device and/or the cartridge may prevent the product located at the charging location from being in fluid communication with the product reservoir so that the product that is being charged cannot flow back into the product reservoir. The device and/or cartridge may alternatively reduce electrically induced emulsion product separation by minimizing the volume of product between the charging location and the exit orifice of the nozzle.

    摘要： An electrostatic spray device that maintains a consistent charge-to-mass ratio in order to maintain a consistent target spray quality is disclosed. During steady state conditions, the high voltage power supply adjusts the output voltage level in response to changing environmental and/or operating conditions. During transient conditions such as start-up, shut-down and changing flow rate conditions, the high voltage power supply ensures that the charge-to-mass ratio is maintained. During, start-up, for example, the high voltage power supply charges the high voltage electrode to a predetermined voltage level before the product is delivered to the charging location. During shut-down, the product delivery is stopped before the high voltage power supply shuts off power to the high voltage electrode, and during changes in product flow rate, the voltage level of the high voltage electrode is adjusted to maintain a consistent charge-to-mass ratio. The present invention also prevents afterspray by discharging the stored charge remaining in storage elements of the high voltage power supply.

    摘要： An X-ray analyzer capable of reducing the effects of a shift of peak positions in an energy spectrum resulting from a change in temperature and a lapse of time in an X-ray detector to enable a highly accurate analysis.A shift of peak positions of X-rays from known positions are detected and a voltage applied to a proportional counter is controlled on the basis of the detected results. In addition, a gain in an amplifier amplifying an output from the X-ray detector may be controlled on the basis of the detected results.
