Abstract: PURPOSE:To make it unnecessary to widen the input dynamic range of a relay even if a reception input is dropped due to rain (etc) by keeping the input level of a frequency converter with the use of a variable attenuator, a directional coupler, a detector and a driver. CONSTITUTION:A reception signal transmitted at a frequency (f) from a communications satellite earth station is inputted to a receiver 12 through a reception antenna 11. Then the signal amplified in the receiver 12 enters an automatic control circuit 13 and then the directional coupler 15 through the variable attenuator 14-1. The passing port of the coupler 15 is introduced to the frequency converter 18 and simultaneously some part is branched. The coupler port is supplied to the detector 16, and some part of the reception signal is detected. The output of the detector 16 is inputted to the input terminal of the driver 17, where the detection output is compared with a reference voltage, and their difference is amplified to change the attenuator 14-a. Accordingly, even if the reception input level is changed due to rain, etc., the input of the converter 18 can be constant by a feedback loop composed a route made of the coupler 15, the detector 16, the driver 17 and the attenuator 14-1.

Title: Method for printing
Inventor: OKADA NAOHIRO
IPC: G03G21/00
Filed: 1990-02-15
Abstract: PURPOSE:To prevent a black line from occurring at the trailing edge part of a paper by making the speed of a resist roller lower than the speed of a fixing roller. CONSTITUTION:When the circumferential speed of the resist roller 5 is set lower than that of the fixing roller 8, the carrying performance of the roller 8 becomes stronger than that of the roller 5. Therefore, the paper 3 is carried toward the fixing roller 8 side in a stretched state and sufficient tension is given to the paper 3 while it is carried. Due to that, even when the trailing edge part of the paper 3 is separated from the resist roller 5, the carrying performance of the paper 3 is secured by the effect of the tension, and the paper 3 resists the frictional resistance performance of a paper guide 9a provided to a part near an image holding body 6. Thus, the contact of the paper and the image holding body such as a photosensitive drum is stabilized and the black line is prevented from occurring.

Title: Binarizing signal processor
Inventor: TAKAHASHI TSUGIO
IPC: H04N1/403
Filed: 1989-02-17
Abstract: PURPOSE:To eliminate the background noises produced by the drop-out colors, etc., over a wide area by detecting the video signal of a light pattern with use of two binarizing threshold values, outputting the binarizing output of the video signal as a discrete pulse signal, and deleting this pulse signal. CONSTITUTION:The video signal that rester-scanned a character picture original is binarized with the 1st threshold value SLA that identifies a character pattern and the 2nd threshold value SLB lower than the value SLA. An optional one of picture elements of the binarized video signal is used as a noted picture element with the picture elements set before and after the noted picture element used as the peripheral picture elements respectively. In the case, a character pulse signal is outputted when both the noted picture element and the peripheral picture element output exceed the value SLA. At the same time, a discrete pulse signal is outputted in the case those picture element and output exceed only the value SLB. Then the discrete pulse signal is eliminated. Thus it is possible to eliminate the background noises over a wide area in such a case where a drop-out color is printed in the depth more than a prescribed level.
