IPC: H04L12/54
Filed: 1992-01-30
Abstract: PURPOSE:To reduce the influence of the error of an encoded picture signal by storing original picture information decoded by a decoder part in a storage part at every prescribed line by a picture information storage control means instead of picture information encoded by an encoder part. CONSTITUTION:The decoder part 14 decodes the picture information encoded by every kind of system to the original picture information when receiving it, and also, decodes the picture information, etc.. read out from a hard disk HDD to the original picture information at need. Also, the encoder part 15 performs encoding by unifying decoded original picture information, for example, the original picture information received from terminal facsimile equipment FAX 1-4 in a prescribed system, and also, enocdes the picture information at need even when the picture information is transmitted. In such a case, a control part 11 stores the original picture information decoded at the decoder part 14 at every prescribed line when receiving it, and stores it in the hard disk HDD instead of the picture information encoded at the encoder part 15. In other words, encoded information can be stored at every prescribed line by replacing by the original picture information.

Title: Image forming device
Inventor: TAKECHI RYUTA
IPC: G03G15/08
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To harmonize a residual toner eliminating function and a surface staining preventing function by using a cleaningless system electrophotographic process. SOLUTION: When a cleaningless system image forming action is executed by utilizing the electrophotographic process that a photoreceptor 6 is saturated and exposed, the residual toner eliminating function and the surface staining preventing function are harmonized by recognizing the quantity of residual toner on the photoreceptor 6 after a transfer process and changing the developing bias of a developing device according to the recognized result. That means, the developing bias is normally held to be a proper value by which surface staining is prevented from occurring and it is lowered so that the recovering ability of the toner by the developing device 8 is enhanced when it is recognized that the quantity of the residual toner is much.  Since the photoreceptor 6 is saturated and exposed, developing potential being difference between the developing bias and the potential of the photoreceptor 6 after the exposure becomes stables without being lowered even when the developing bias is lowered. Thus, image quality is maintained.

IPC: A61B8/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a digital orthogonal detection method and device capable of easily varying a reference frequency. SOLUTION: Coefficient sets k1i, k2i, k3i, k4i, for calculating, through interpolation operations and from four digital data d11, d12, d13, d14, interpolation digital data E1 at each time that divides a digital data sampling period Ts by (m), are stored in a coefficient table 105. Frequency varying parameters (n) are outputted from a timing control circuit 103 in a period of 'Ts +n (Ts/m)' and are accumulated and added together by an accumulator 104 that performs cyclic cumulative additions from '0' to 'm-1', and the coefficient sets K1i, K2i, K3i K4i are selected and set according to a sum (i) to calculate the interpolation digital data E1. The interpolation digital data E1 calculated, or interpolation digital data '-E1' obtained by inverting the sign of the data E1, or '0', is selectively outputted.  Thus, the reference frequency of digital orthogonal detection can be varied finely by varying 'n'. Use of this method in an ultrasonic diagnostic device allows dealing with spectrum shifts.
