Abstract: PURPOSE:To code a picture signal with a high coding efficiency by exchanging the order of two kinds of arithmetic operations. CONSTITUTION:An input picture signal is fed to a terminal 10 and at first transformed into a DCT coefficient by a DCT arithmetic circuit 20. Then the DCT coefficient of an input picture outputted from the DCT arithmetic circuit 20 and a DCT coefficient of a preceding screen stored in a frame memory 70 are subtracted at a DCT coefficient domain by a subtractor 30 and the result is outputted as a difference. The difference is quantized by a quantizer 40 and outputted as a quantized value to be sent to an output terminal 80. On the other hand, the quantized value is fed also to an inverse quantizer 50 and decoded into the difference. The difference is fed to the DCT coefficient of the preceding screen from the frame memory 70 by an adder 60 and a new prediction DCT coefficient is generated. Thus, the input picture is at first transformed into the DCT coefficient and the inter-frame difference calculation is executed at the DCT coefficient to attain high speed processing.

Abstract: PURPOSE:To surely prevent paper from being wound by pressing and bringing a fixing roller on which an elastic rubber layer is formed into contact with a pressure roller and then rotating a metallic destaticizing roller. CONSTITUTION:On the surface of the fixing roller 8 on which the elastic rubber layer 16 is formed, the surface of the pressure roller 32 comes into contact with a paper onto which a toner layer is transferred, and the pressure roller 32 induces negative electrification. However, following the electrification, the grounded metallic destaticizing roller 34 rotates to be in contact with the fixing roller, whereby the surface of the fixing roller 8 is always destaticized. On the surface of the pressure roller 32, the surface of the fixing roller 8, the rear surface of the paper onto which a toner layer is transferred, and a charge imparting means being an oil applying means including an oil impregnating felt 24 and a blade 26 come into contact with each other to induce negative electrification. Consequently, the pressure roller 32 is negatively electrified to develop a great difference in potential between both rollers, and the already fixed paper is pulled toward the pressure roller 32 and is ejected.

Title: Pressure roll for electrified roll
Inventor: FUKAZAWA HARUO
IPC: C21D9/62
Filed: 1994-11-22
Abstract: PURPOSE: To keep the contact pressure uniform at the time when an object material for heating is brought into contact with an electrified roll and carry out electric communication while preventing spark generation by keeping a gap between a shaft and a shell formed in the outer circumference of the shaft. CONSTITUTION: A presser roll 1 for an electrically communicating roll 3 is used for pressing an object material 2 for heating on the electrically communicating roll 3 and a gap is kept between a shaft 5 and a shell 4 formed in the outer circumference of the shaft 5. When the material 2 passes between the roll 1 and the roll 3, the shell 4 forms a dent, which is though a slight dent, at the contact point between the shell 4 and the shaft 5 due to the pressure of the shaft 5. At that time, since the gap is kept between the shaft 5 and the shell 4, the shell is deformed into a rather flat shape and the contact between the shaft 5 and the shell 4 changes from a linear contact to a face contact and at the same time, the contact between the shell 4 and the material 2 also becomes a face contact and the contact arc length is extended.  Consequently, pressure is applied almost uniformly to the material 2 at the contact part between the material and the shell 4 and electricity can be communicated while spark generation being prevented.
