Title: Image forming device
Inventor: MASUDA TAKASHI
IPC: G03G15/00
Filed: 1992-04-13
Abstract: PURPOSE:To improve the ability of peeling and separating a non-image sheet by controlling a transfer output at the initial stage in the feeding of the sheet to a transfer part and at a stage in the course of the passing of the sheet through the transfer part, so that when a carrying force is exerted on the non-image sheet by a sheet feed roller, the sheet is not electrostatically attracted, and when the carrying force is not exerted thereon, it is electrostatically attracted. CONSTITUTION:In a transfer part 4, when a sheet 100 does not have an image thereon, the transfer output is set to OFF at the initial stage in the feeding of the sheet to the transfer part 4 and is set to ON at the stage in the course of the passing of the sheet 100 through the transfer part 4. Therefore, by setting the transfer output to OFF at the initial stage in the feeding of the sheet 100 to the transfer part 4, the sheet 100 is not attoracted to a photosensitive drum 1 at the stage, so that the ability of the sheet 100 to be separated from the photosensitive drum 1 is improved. Since the transfer output is set to ON at the stage in the course of the passing of the sheet 100 through the transfer part 4, an electrostatic attracting action is generated accompanying that, between the photosensitive drum 1 and the sheet 100, and a force for carrying the sheet 100 is exerted by this action and the rotating action of the photosensitive drum 1. Thus, the occurrence of a jam can be suppressed.

Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To accurately and simply measure the concn. of gas continuously for a long time by applying voltage inverse to that at a time of measurement when the applied voltage/limit current value characteristic of a sensor is deteriorated. SOLUTION: A sensor 1 has plate-shaped ceramic heater 20, a stabilized zirconia substrate 10 being a solid electrolyte plate showin oxygen ion conductivity, an anode 3 and a cathode 2. The voids 7 of the cathode 2 are also used as gas diffusion restricting pores restricting the diffusion amt. of gas to be measured and the concn. of gas is measured on the basis of a limit current value generated when DC voltage is applied across the electrodes 2, 3. When this sensor is used for a long time, the surfaces of the electrodes 2, 3 are contaminated and the voltage-current characteristic of the sensor is changed to generate an error in output.  Herein, when voltage inverse to that during usual measurement is applied across the electrodes, that is, voltage is applied so that the anode 3 becomes negative and the cathode 2 becomes positive, the characteristic of the sensor can return to an initial value. Therefore, the concn. of gas can be again accurately measured by the sensor.
