Title: Detector of toner density
Inventor: YAMADA HIROSHI
IPC: G01N27/72
Filed: 1981-02-09
Abstract: PURPOSE:To realize the accurate detection of the toner density without giving any effect to the circulation of the developer within a magnetic brush developing device, by incorporating a detecting coil that detects the toner density from the variation of inductance into a hollow pipe made of an electrically insulated material. CONSTITUTION:A detecting coil 10 is put into a cylinder 14 made of an electrically insulated material and attached fixedly to a side plate 2 and close to a gate 9 of a developing dvice. The magnetic flux of the coil 10 passes through the outside of the coil, i.e., a carrier contained in the developer. The amount of the carrier varies by the toner density, and accordingly the resistance varies for a magnetic path through which the coil magnetic flux passes. This variation of the resistance is finally detected in the form of a change of inductance. Accordingly, the thinner the thickness of the cylinder 14, the higher the sensitivity of detection.

Title: Method for compressing data and machine readable recording medium storing compression program
Inventor: TAKIZAWA TETSUO
IPC: G06T1/20
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To attain a high compression ratio independently of the kind of an image. SOLUTION: In each input of a pixel value from an image to be compressed, a comparing means 14 compares the pixel value with a preceding pixel value just before stored in a storage means 17, and when both the values match with each other, counts up the contents of a conter 14a and processes a succeeding pixel value. At the time of nonmatching, a matching code setting up a continuous number is outputted when the value of the counter 14a is >=1, and then a comparing means 15 checks whether the pixel value matches any one of past pixel values stored in a storage means 18 or not. When matching is obtained, an index code setting up the index number of the pixel value is outputted, the contents of the storage means 17 are rewritten and a succeeding pixel value is processed.  When there is no matching pixel value in the past pixel values, a difference acquiring means 16 finds out a difference from the just preceding pixel value, and when the difference value is less than a prescribed value, outputs a difference code setting up the difference value. In the other cases, the means 16 outputs an immediate value code setting up the pixel itself, the contents of the storage means 17, 18 are rewritten and a succeeding pixel value is processed.
