    摘要： A data logging apparatus for a device function tester comprises a first shift circuit (1) supplied with an output signal of the tester and a strobe signal for shifting the output of the tester by n rates under the timing of a basic clock (T.sub.0), a second shift circuit (2) for shifting the timing of the basic clock (T.sub.0) by n rates, a write pulse generating circuit (3) supplied with the output signal of the shift circuit (2), a third shift circuit (4) supplied with a memory address signal for shifting it by n rates under the timing of the basic clock (T.sub.0), a fourth shift circuit (5) for shifting a pattern address signal by n rates under the timing of the basic clock (T.sub.0), a first memory (6) supplied with the output signal of the first shift circuit (1) and the output signal of the third shift circuit (1) for storing the result of the test shifted by n rates in response to a write command signal, and a second memory ( 7) supplied with the output of the fourth shift circuit (5) and the output of the third shift circuit (4) for storing the pattern address shifted by n rates in response to the write command signal. Data logging can be accomplished without being affected by variable time intervals of write enable strobe pulses.

    摘要： In an image forming apparatus for forming a static latent image using ions as a medium, an ion generation formed by stacking a plurality of line electrodes, a plurality of finger electrodes, and a screen electrode with dielectric layers being sandwiched therebetween is arranged to oppose a dielectric drum on which the electrostatic latent image is to be formed. A static induction transistor for switching an RF high-voltage signal at a high speed is connected to each line electrode of the ion generator. Each static induction transistor is also connected to a DC high-voltage power source via a coil. When each static induction transistor is driven at a high frequency by a source drive circuit, an RF high voltage is applied to a corresponding line electrode. A voltage is supplied to a parallel resonator constituted by the coil and a line electrode capacitance to start resonance, thereby obtaining an output for ion generation.
