IPC: G03G15/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of reducing simply and surely deterioration in an image quality such as density unevenness and color slippage caused by fluctuations in a load occurring when a recording sheet is fed to a transfer position or carried from the transfer position to a fixing means. SOLUTION: An image forming device is set so that the rear part of a recording sheet is sent out from a paper feeding roll (in a state where the speed is increased) to be separated, while the interval between image forming regions on a photoreceptor passes through at least one of an exposure position and a transfer position. Similarly, the device is set so that the front part of the recording sheet rushes into a fixing means during the above-mentioned period. Similarly, the device is set so that the rear part of the recording sheet is sent out from between a transfer means and the photoreceptor or an intermediate transfer body to be separated during the above-mentioned period.

IPC: H01L23/12
Filed: 1989-06-08
Abstract: PURPOSE:To accurately braze a stage onto a base by a method wherein a recessed part into which the lower part of the stage can be fitted is formed on the surface of the base and a peripheral edge at an opening part of the recessed part is scraped and a brazing-material reservoir part is formed. CONSTITUTION:A recessed part 12 into which the lower part of a stage 16 can be fitted is formed on the surface of a base 10; a peripheral edge at an opening part of the recessed part 12 is scraped; a brazing-material reservoir part 14 is formed at the peripheral edge at the opening part. In a state that the lower part of the stage 16 has been fitted into the recessed part 12, the stage 16 is brazed onto the base 10. As a result, during this brazing operation, a brazing material 18 which is going to creep up to a circumferential side-face of the stage 16 is dropped to the brazing-material reservoir part 14 by an action of gravity to which the brazing material 18 is subjected or by an action of surface tension by which the brazing material 18 reserved inside the brazing- material reservoir part 14 is subjected. Thereby, the stage can be brazed accurately onto the base without applying the brazing material between the circumferential side-face of the stage and the surface or the base by drawing a meniscus shape.

Abstract: PROBLEM TO BE SOLVED: To widen a capture range as wide as possible and to reduce the clock jitter at the time of phase synchronization by detecting the output level of a delay means at the rise or fall based on a reproducing data signal and chang ing the loop gain. SOLUTION: A phase comparator 4 performs phase comparison of a reproducing data signal with the output of a frequency divider 14 inverted through an inverter 15 and a signal corresponding to the phase difference is sent to a charging pump 81 through a switch 6b. A loop gain becomes a loop gain determined by the current value of the charging pump 81 when the phase difference is <±90 deg. and when it is >=±90 deg., the loop gain becomes a gain determined by the current sum of charging pumps 81, 82. When VCO 12 oscillates at the objective frequency and is phase synchronized, the phase difference becomes zero and the clock jitter is determined by the current value of the charging pump 81.  When the oscillating frequency of VCO 12 is deviated from the objective frequency, the phase difference is gradually changed, becomes ±90 deg., the loop gain in a phase comparator 42 is increased and the capture range is widened.
