Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To eliminate irregularities in an image caused due to the potential memory of an image carrier, without causing a deterioration in the image carrier by controlling an auxiliary electrifying means, in accordance with the intervals of transfer materials when consecutively forming the images. SOLUTION: For electrifying a photoreceptor drum 4 simultaneously with a full surface exposure, the auxiliary electrifier 15 and a discharge lamp 25 are piled up to provide at the same place on the surface of the drum 4. This drum 4 is electrified (first electrification) by the auxiliary electrifier 15 and simultaneously, exposed for destaticizing by the discharge lamp 25, so that the memory effective region of the drum 4 previously obtains the same polarity as that of an electrostatic latent image formed on the drum 4, that is, a negative polarity, prior to the primary electrification of the drum 4. At this time, the auxiliary electrifier 15 is controlled by the intervals of the transfer materials when consecutively forming the images.  In other words, in a device having the paper intervals of the transfer materials equal to or longer than the circumferential length of the drum, the primary electrification of at least two or more times is attained up to the next image formation, because of a strong memory effect at the tailing edge Pa of the transfer material.

Title: Transmission system, transmitter and control loop for time-shared multiple signal transmission
Inventor: BUINFURIITO BIRUTO
IPC: H03G3/20
Filed: 1994-07-25
Abstract: PURPOSE: To provide a transmission system by generating a control voltage from the difference between the voltage of a detector and a reference voltage value upon which the no-load voltage of the detector is superimposed. This system can be stabilized easily and can maintain its operating function irrespective of the temperature dependency of the detector. CONSTITUTION: A detector 2 detects the electric power of the high-frequency output signal RFout of a power amplifier 1 and converts the electric power into an actual- voltage Uist and the voltage Uist is used as the control variable of a control circuit. Then a control voltage Uc which is used as a setting value is determined from the deviation signal USO11 -Uist . The voltage USO11 is a target voltage and corresponds to a reference. Then the time-characteristic and power level of the output signal RFout of the controllable power amplifier 1 are determined by the time-characteristic and magnitude of the reference value USO11 . In addition, since the no-load voltage UO of the detector 2 is superimposed upon the voltage USO11 in a circuit block 3, the difference between the voltages impressed upon both input sides of a control voltage generator 5 becomes equal to (USO11 -Uist ). Therefore, the dependency of the amplifier 1 upon the voltage UO is eliminated, because the action of the voltage UO is eliminated.

Title: Liquid discharging apparatus
Inventor: MAEKAWA ETSUICHI
IPC: B41J2/055
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To suitably remove a foreign matter by adding a mechanical vibration, whose conditions change with time, to a liquid in a liquid discharging unit in the case of discharging the liquid from the unit. SOLUTION: An electro-mechanical transducer 24 is vibrated by a drive signal from a driving circuit 100' by switching a switch S. The vibration of the transducer 24 is transmitted to an ink via a flexible wall 22 and vibrated. The transducer 24 is driven by the circuit 100' in parallel at the time of sucking an ink by covering a nozzle surface of a print head 2 with a cap. Thus, the ink is sucked by a sucking unit while giving a vibration to the ink of an ink liquid chamber 23. Thus, the vibration changed under conditions such as a frequency, an amplitude width or the like is applied to the ink so that a foam or a solid material of a shape in a various size adhered to an inner wall of the chamber 23 or the nozzle is easily released and is scarcely readhered, and hence it can be easily discharged along with a flow of the ink by the sucking.
