Title: Method and device for adaptive conversion encoding
Inventor: SUGIYAMA AKIHIKO
IPC: G10L19/00
Filed: 1989-12-13
Abstract: PURPOSE:To compress auxiliary information and to improve encoding quality by varying block length by using the difference between blocks of a normalized signal obtained by normalizing an input signal. CONSTITUTION:The best block length is selected by using the difference between blocks of the normalized signal obtained by normalizing the input signal with different block length and the normalized signal corresponding to the best block length is converted linearly and quantized to transmit information. Namely, a linear converting circuit 3 performs discrete linear conversion by using the best block length supplied from a selector 27 and supplies the obtained conversion coefficient to a quantizer 4 and a bit distributing circuit 6. The bit distributing circuit 6 distributes bits by using the conversion coefficient supplied from the linear converting circuit 3 and the quantizer 4 quantizes the conversion coefficient supplied from the linear converting circuit 3 by using the bit distribution information. The quantized conversion coefficient and bit distribution information are multiplexed by a multiplexing circuit 15 with the optimum block length and the dispersion value of the input signal and sent out to a transmission line 8. Consequently, the auxiliary information is compressed to improve the encoding quality.

Title: Electrophotographic device
Inventor: NIMATA YUKIO
IPC: G03G15/06
Filed: 1987-12-23
Abstract: PURPOSE:To keep a constant potential difference between the potential of an image part and the potential of a non-image part and to always stably obtain a distinct image by connecting a power source for electrification between a bias power source and an electrifying device provided closely to the exposed surface of a photosensitive body. CONSTITUTION:An electrostatic latent image is formed on the exposed surface 2 of an electrostatic latent image holding body 1 with the voltage Vo of a grid part 10 and the potential is Vo. Thereafter, the potential of the non-image part lowers from Vo to Vr by exposing only non-image part of the exposed surface 2. Meanwhile, the potential of the unexposed image part is still Vo. Since the potential of the surface of a developer carrier 12 is set Vb at the time of developing, developer 13 is attracted to the image part according to the potential difference Vo-Vb in the image part. On the other hand, since the potential difference Vb-Vr is a potential distribution in a direction opposite to the potential distribution in the image part in the non-image part, the developer 13 is not attracted to the non-image part and the constant potential difference can be always kept between the potential of the image part and the potential of the non-image part. Thus, the distinct image can be always stably obtained.
