IPC: H03L7/26
Filed: 1986-11-04
Abstract: PURPOSE:To increase the stability of an oscillator, miniaturize and reduce the price by executing alternately the action to stabilize the oscillating frequency of a voltage control crystal oscillator based on the output of a light detecting device and the action to stabilize the oscillating wavelength of the laser for excitation. CONSTITUTION:A resonance output, in short, the output of a light detecting device 4 depends on both of the oscillating frequency of VCXO 9 and the oscillating waveform of a laser 2 and to control simultaneously both is not very easily.

On the other hand, while the laser control circuit 11 is operated, the VCXO control circuit 8 is kept at the output value immediately before it. Thus, by the output of a detecting circuit 7, the VCXO control circuit 3 and the laser control circuit 11 are operated by the time division, the control of the VCXO 9 and the laser 2 for excitation is alternately executed and the stable oscillating action can be kept.

Since the judged result from the device 5 is judged on the basis of the operating-judgment time, for the facility of its own, which is computed on the basis of the actual operating state of the facility, it is treated as a slight fault. In addition, since the judged result from the device 7 is judged on the basis of the control time for the apparatus itself, the abnormality state of the facility is diagnosed as advanced considerably, and it is treated as a serious fault. Thereby, the defect detection sensitivity of the facility can be enhanced.

Abstract: PURPOSE:To obtain a simple, stable developing mechanism, and to achieve quality enhancement and cost reduction by providing the developing mechanism with a gaseous ions generating past interposed between the misty ink and the electrostatic latent image surface. CONSTITUTION:Negative ions generated near a wire 32 are induced by E10 and E11, outside air flows from a suction hole 38 provided on a counter electrode 33, and consequently ion blow is generated in a direction shown by an arrow B. Negative pressure is produced near the space 39 of a chamber 20 by the ion blow, and ink mist 40 filled in the chamber 20 is sucked into the direction shown by the arrow B. It joins the ion blow and is electrostatically charged. The charged ink mist is accelerated by the E11, sticks to a printing part 35, and is developed. The ink mist does not stick to a nondevelopment part 36 since it is intercepted by the reverse electric field E11. Since a simple-structured developing unit which does not have a recovering mechanism and a complex ink-carrying mechanism is realized, it is effective for device miniaturization, cost reduction, and quality enhancement.
