Title: Electrostatic latent image developing device
Inventor: MIZUNO HIROSHI
IPC: G03G15/08
Filed: 1987-03-03
Abstract: PURPOSE:To always obtain the images of uniform density by providing a crest height control member, which faces a developing sleeve, in the area through which a developer reaches a part facing a toner supply roll and forming a developer retaining part above this control member in the developing carrying direction and arranging a magnetic body in the vicinity of this part. CONSTITUTION:When the developer which passes a developing area X reaches the part facing a crest height control member 8, the crest height is controlled and most of the developer is dropped to a developer retaining part 9. This dropped developer is mixed with a carrier and the developer, retaining in this part 9. Since the developer in the developer retaining part 9 is restricted in the magnetic brush state by a magnet incorporated in a magnetic roll 7 and a magnet 20 attached to a casing 4, the developer is stably and uniformly brought into contact with the surface of a developing sleeve 6 without convection while forming an eddy or the like in the developer retaining part 9. Thus, the developer supply to the surface of the developing sleeve 6 is not fluctuated and the images of uniform density are obtained.

Title: Oscillating circuit of proximity switch
Inventor: UEDA KENJI
IPC: H03K17/95
Filed: 1983-03-24
Abstract: PURPOSE:To attain oscillations of high frequency by providing a discharging circuit for electric charge which is charged up to the parasitic capacity of a transistor for emitter follower. CONSTITUTION:Transistors Tr1 and Tr6 function as complementary amplifiers which use the voltage of a parallel resonance circuit as the inputs. The parasitic capacity Cd existing between the emitter and the earth of Tr1 and Tr6 respectively is charged by the Tr1 in a positive half cycle and discharged via the Tr6 in a negative half cycle. Thus the charging/discharging time of the capacity Cd is shortened, and a waveform same as the generated voltage of the resonance circuit is obtained in the form of the emitter voltage of a Tr4. Thus it is possible to prevent the evil effect of the capacity Cd and to increase the oscillation frequency. This improves the high frequency characteristics.

IPC: H04N11/20
Filed: 1984-03-16
Abstract: PURPOSE:To suppress vertical flicker generation by detecting a sudden change of a luminance difference signal and inhibiting the detecting operation of a motion detector according to the detection. CONSTITUTION:The motion detector consists of an absolute value circuit 10a, flicker suppressing circuit 10b, and motion detecting circuit 10c. A figure A shows luminance signal values (y) of scanning lines ln-2-ln+2 in fields fN and fN-2, and a figure B shows luminance difference signal values DELTAy extracted from A similarly. The reference level VR when abrupt variation in luminance difference occurs corresponding to the current scanning line ln is obtained by adding a set-up voltage VS to the mean value VA of luminance difference signal values corresponding to scanning lines ln-1 and ln+1 which are right before and behind said scanning line; and the luminance difference signal value corresponding to the scanning line ln increases above the reference level VR, the output of a comparator 38b is ''H'' and outputs of comparators 38a and 38c are ''L'', and a switch 41 selects and sends out the mean value VA, so only a little variation in luminance difference signal value is supplied to the motion detecting circuit 10c as the trailing stage, so that detection is not performed.
