Title: Picture forming device
Inventor: YAMAJI MASAAKI
IPC: H04N1/04
Filed: 1982-07-20
Abstract: PURPOSE:To execute good picture control, by using a sensitivity compensating filter for a CCD, and making its overall sensitivity characteristic equal to an overall characteristic of a photoconductive layer, in a picture forming device which uses the CCD as a developing bias setting sensor. CONSTITUTION:Reflected light from a picture of an original P which transmits a half mirror 19 transmits a filter 4, converges to a CCD 3, and the photodetected CCD 3 sends out successively a photoelectric converting signal by a driving means 21. This signal passes through an amplifier 22, is converted to a digital signal by an A/D converter 23, and is inverted by a picture forming means 24. This inverted signal becomes the relation proportional to the charged potential on a photoconductive layer of a photosensitive drum 7 on which an electrostatic latent image of an original in the same part is formed. The inverted signal becomes the relation inversely proportional to a photodetector, therefore, the potential of this inverted signal becomes low in porportion to the charged potential of the photoconductive layer of the photosensitive drum 7. As a result, good picture control can be executed.

Title: Packet data transmission and memory storage system
Inventor: OZAKI NAOHIKO
IPC: H04L12/911
Filed: 1988-05-25
Abstract: PURPOSE:To improve the utilizing efficiency of a buffer memory by storing a packet data continuously without any gap into a buffer memory and using other means so as to provide sections of packet data. CONSTITUTION:The packet data outputted from an output circuit 1-3 is stored in a memory 1-1 through a packet data line 1-5. The packet data in the memory 1-1 is processed and decreased, but if packet data much more than the decrease are transferred from the packet data line, the memory is saturated. Thus, number of idle memories is informed from the memory 1-1 to a memory monitor circuit 1-2 through an idle memory number display signal line 1-7 and if the memory monitor circuit 1-2 estimates the production of saturation of the memory 1-1 by the information, a congestion control signal is transferred to the signal line 1-6. When the congestion control signal is received, the output control circuit 1-4 outputs the output inhibit signal to the signal line 1-8 and the output of the packet data from the output circuit 1-3 is stopped. Thus, the saturation of the packet data is prevented.
