Title: Image forming device and image processor
Inventor: TAKAMATSU MASAHIRO
IPC: H04N1/409
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To prevent reduction in the density at a rear end in contact with a background of a medium tone part when a value of an output image changes from a medium tone part into a value of the background part in a subscanning direction with a simple and small-scale processing in the image forming device adopting an electrophotography method. SOLUTION: A rear edge of a medium tone part 1 in contact with a background part 2 is extracted, and image data in a background area consisting of m-pixels after the rear edge in input image data Si in the subscanning direction are revised to a setting value Dc based on correction data Sc. The setting value Dc is set to a value slightly lower than a threshold Dth equivalent to a dot area rate of an image reproduction start point.  In the case that the medium tone part whose image data value is higher than the threshold Dth denoted by input image data Sib or a background part whose image data value is higher than the setting Dc is in existence in an area consisting of m-pixels after the rear edge of the medium tone part 1 denoted in input image data Sia in the subscanning direction, image data value of the part is not revised and only the image data value from the rear edge of the medium tone part 1 to that part is revised to the set value Dc.

Filed: 1987-11-25
Abstract: PURPOSE:To sufficiently eliminate the high frequency component of a ghost by providing a high pass compensating circuit to compensate the high pass component of the output signal of a first memory circuit and storing a signal to have flat amplitude frequency characteristics in the band of a video signal into a second memory circuit. CONSTITUTION:A filter 1000 to compensate the high pass component is inserted between an output waveform memory 111 and an arithmetic circuit 108, and the sinX/X pulse of a band area 4, 2MHz is written into a reference waveform memory 113. By the filter 1000 to compensate the high pass component, the high pass components of the pulse waveform obtained by differentiating the leading edge of a vertical synchronization signal outputted from the output waveform memory 111 is compensated so as to be flat in the band, and the reference waveform to seek for the correlation with this is made into the sinX/X pulse. Thus, since the detection of the ghost is equalized with the detection of the sinX/X pulse, the high pass component of the ghost can be sufficiently eliminated.

Filed: 1986-12-12
Abstract: PURPOSE:To facilitate the cleaning of the principal part, to reduce cleaning frequency and to reduce the effect of the flow of a solid dissolved liquid, by providing a solvent injection port and a liquid jet port to a first chamber of a diaphragm part and providing a pressure transmission liquid injection port to a second chamber thereof. CONSTITUTION:At first, slaked lime and water are introduced into a slaked lime dissolving tank and, at the same time, water is also injected in a first chamber 17 of a diaphragm part 15 from a water injection port 21. At this time, since a piercing hole 13 and the first chamber 17 are small as compared with the dissolving tank 2, the concn. of slaked lime in the first chamber 17 does not become high. Even when a stirrer 14 is subsequently operated and a high concn. slaked lime dissolved solution 5 is ready to penetrate in the first chamber 17, the penetration of said solution is prevented or suppressed by the water stream flowing out from the first chamber 17. Therefore, slaked lime adhered to and solidified on a diaphragm 16 is reduced and, as a result, cleaning frequency may be reduced. Water is injected to the diaphragm part 16 from the water jet orifices 22, 23 of the diaphragm part 15 to allow waste water to flow out from the water injection port 21 to make it possible to easily clean slaked lime adhered to and solidified on the diaphragm 16. Further, in a liquid level measuring apparatus 26, the liquid pressure of the solid dissolved solution 5 is transmitted to a pressure sensor 14 through the oil 20 in a second chamber 18 and pressure variation is relaxed corresponding to the amount of the oil 20.
