Title: Image-forming apparatus and printer
Inventor: HORI KENJIRO
IPC: H04N1/113
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To form a high-quality total image, by measuring an interval between detection pulses in a detection pulse group, inputting a single pulse determining a reference time from the detection pulse group and pulse interval data, and changing an adjustment time before an image signal is started to be output. SOLUTION: A beam interval corresponds to output pulses by a first laser and a second laser of a beam detector 10, and output pulses by the second laser and a third laser of the beam detector. A beam detection pulse row output from the beam detection circuit 10 is measured by a pulse interval-measuring circuit 11. A CPU 14 outputs to an image start timing-adjusting circuit 15-17 in accordance with an input value from an A/D converter circuit 13. The image start timing-adjusting circuits 15-17 delay a single pulse generated by a pulse shaping circuit 12 by a delay signal output from the CPU 14 and output an image start timing to image signal-generating circuits 18-20. A total signal without an image shift in an operation direction is thus obtained.

Title: Latch up measuring method of integrated circuit and voltage generation circuit using the same
Inventor: KOKUBO SHIGERU
IPC: H01L27/092
Filed: 1992-03-25
Abstract: PURPOSE:To enable latch up measurement free from the effect of a floating inductance by applying a voltage by a specified waveform to terminals of an IC. CONSTITUTION:In connection to voltage sources 21-24 ranging voltages V1-V4 with a relay sequentially according to time T1-T4 a voltage waveform is obtained automatically. The latch up measurement of an IC is based on changing the voltages V1-V4 and the time T1-T4. Values of the voltages V2 and V3 and the time T2 and T3 are set so as to al low the generation of a latch up according to the IC to be tested and a terminal voltage and thereafter, a voltage value and application time approximate to the values are detected. This eliminates the charging of a capacitor with an electric charge and hence, there is no eventual deficiency, for example, variations in the results of testing or each measurement with no effect of a floating inductance thereby stabilizing a latch up reference value.
