Title: Image forming device
Inventor: NAGAO HIROYUKI
IPC: G03G15/00
Filed: 1992-04-27
Abstract: PURPOSE:To prevent the mulfunction and damage of a stain detecting means and to accurately detect soiling by providing the stain detecting means on a low-temperature part of the lower side of a lower fixing roller side, and attaining cleaning when the soiling of the lower fixing roller is detected. CONSTITUTION:The stain detecting means 40 is provided opposite to the lower fixing roller 23, in the vicinity of the lower fixing roller 23 lowered downward two-third or more from the press-contact surface of the lower fixing roller 23 with an upper fixing roller 22. Because, in this location, the lower side of the roller 23 has the lowest temperature distribution, so that adverse influence is not exerted on the stain detecting means 40. The soil detecting means 40 detects a change in the output of a phototransistor, caused by reduction in the reflected light quantity of light projected by a light emitting diode as the lower fixing roller 23 is soiled, as soiling. When the value of the soiling exceeds a reference value set in advance, a circuit is changed from high to low, to inform the fact to a master CPU. The master CPU obtaining the information of the soiling, sets a cleaning mode, to clean the lower fixing roller 23.

Filed: 1994-05-23
Abstract: PURPOSE:To correct longitudinal line mis-convergence while keeping the linearity of coma aberration correction by connecting a correction coil to a vertical deflection coil via a circuit comprising an impedance element and a diode. CONSTITUTION:Let a vertical deflection current Iv as shown in figure be a positive direction, then a diode 10a is conductive when a vertical deflection current Iv is a large negative value and a current Ia reaches a current larger than a current Ib. Thus, the current component Id=(Ib-Ia)/2 being a division of a difference between the currents Ib and Ia by 2 corresponds to a remaining current component subtracting the current component I/2 averaging the currents Ia, Ib from them and generates correction magnetic fields 15c, 15d of 4 poles. The correction magnetic fields 15c, 15d produce forces 16B, 16R to both-end electronic beams 14B, 14R. As a result, YH mis-convergence in which longitudinal lines 18B, 18R drawn by the both-end beams 14B, 14R are deviated as a bow shape is corrected.

Abstract: PROBLEM TO BE SOLVED: To inexpensively manufacture a dynamic vibration absorber and to effectively reduce torsional vibration of a specified rotational frequency and torsional vibration of a specified order. SOLUTION: This dynamic vibration absorber is provided with a constant vibration frequency type vibration absorbing system D1 in which an annular mass 2 is concentrically connected with a hub 1 via an annular elastomer 3 and a vibration frequency variable type vibration absorbing system D2 constituted of a plurality of centrifugal masses 4 arranged so as to perform pendulum motion by drawing circular arc shaped loci with an axial center P of a pin 5 implanted in the hub 1 as a center.
