Title: Rectifier device
Inventor: MOTOKI TAKAHIRO
IPC: H02M3/155
Filed: 1988-10-07
Abstract: PURPOSE:To suppress the distortion of a current by so controlling ON and OFF of a switching element that the width of target upper and lower limit values is varied synchronously with an input voltage waveform using results of comparison of flowing current detection signals. CONSTITUTION:A rectifier is composed of a diode bridge 2 for converting commercial power source 1 into a DC, a noise filter 3, a stepup chopper 4, a current detector 5, an output voltage detector 6, and a controller 7 to supply a power to a load 8. A current instructing circuit 9 is provided to calculate a current command value I1 and to output it. In this case, a current waveform control circuit 11 controls a current waveform on the basis of a detection signal from the detector 5 and a command vale from the circuit 9, and is composed of amplifiers 11a-11b, an analog switch 11, and a comparator 10d. Thus, the element of the chopper 4 is so controlled ON,OFF that the width of target upper and lower limit values of a flowing current waveform becomes zero at its zero point synchronously with an input voltage waveform on the basis of the compared result.

Title: Driving device for waste toner carrier
Inventor: TATSUMI KENZO
IPC: G03G21/10
Filed: 1991-10-01
Abstract: PURPOSE:To evade pollution caused by waste toner in a device by adopting constitution that a waste toner carrier is not driven even if the device is operated in a state where a waste toner recovery part is unset. CONSTITUTION:The waste toner dropped in a waste toner carrying tube 6 from a cleaning unit 5 is discharged to the waste toner recovery part 3 of a developing unit 1 by the rotation of a waste toner carrying coil 7 by a driving gear 10 via an idle gear 11. The idle gear 11 is interlocked with a driving position where it is engaged with both of the driving gear 10 and an output gear 12 and a neutral position for which the idle gear 11 is separated from the driving gear 10 by interlocking with the mounting action of the developing unit 1 by a bracket 14. In other words, the sliding of a sliding member 21 slid by the attaching/detaching action of the developing unit 1 is transmitted to the bracket 14 via pulleys 17 and 18. Thus, in the state where the developing unit 1 is not mounted, the waste toner carrying coil 7 is not rotated and the waste toner is never discharged.

Abstract: PURPOSE:To facilitate the detailed adjustment of a slip design by setting reference points at the specific number of areas in a rectangle to designate the sticking coordinates of the rectangle and also to select one of those reference points so that logotypes and marks are displayed. CONSTITUTION:A logotype sticking menu is first selected with input of logotype numbers. Then the sticking coordinates are inputted.

Then a reference point is decided for designation of a sticking position on a tablet. That is, the reference point P4, for example, is selected and magnification or reduction is designated for the logotype size. Thus the logotype 200 is magnified or reduced on the basis of the position of the point P4 and displayed on the screen. Then the logotype 200 is confirmed by an operator and set to be sticked. If the change of the logotype 200 is desired, the sticking coordinates are inputted. Thus the detailed adjustment is facilitated and a designed slip is immediately sent to a printing process.

Abstract: PURPOSE:To detect the individual emitted light quantity of plural light emitting points and also to control these emitted light quantities by using a light source having plural light emitting points and separating spatially the luminous fluxes which are divided by a luminous flux dividing means set into an optical path reaching an optical recording medium from the light source. CONSTITUTION:The signals corresponding to the emitting condition of each LD array 1 are sent to a laser control part 13 from an interface 11 of an optical recording/reproducing device via an encoder 12. A laser driver 14 drives each LD 2 in the array 1 based on the output of the part 13. The luminous fluxes received from the LD 21, 22, 23... are turned into the parallel fluxes by a collimator lens 3 and diffracted on an incident surface 20a of a beam shaping prism 20. These diffracted beams are sent to a beam splitter 4 after the conversion of the beam forms. A reflecting film having a prescribed reflection factor is vapor-deposited on the surface 20a. Thus the beams sent from the lens 3 are partly reflected. These reflected beams are separated by a luminous flux separating means serving as an image formation system 22 into pieces in number equal to the number of LD 2, and separated and formed as the spatial image.
