Title: Electrophotographic photoreceptor and electrophotographic device using the same
Inventor: TAKAGI SHINJI
IPC: G03G15/02
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To restrain a flaw caused on the surface of a photoreceptor having a protection layer made of photoset acrylic as a surface layer when electrified carrier leaked from a magnetic brush is pressed to the surface at the time of transfer by blending plastic resin by specified amount in three-dimensionally crosslinked acrylic resin in the surface layer. SOLUTION: The plastic resin is blended by 20 to 30% in acrylic in the surface layer of the photoreceptor used for an injection electrification process using the magnetic brush as the electrifying member of an electrifier and having the protection layer constituted of the photoset acrylic resin as the surface layer. By using the acrylic having a large functional number, the surface of the photoreceptor is cracked to cause a deep flaw when the leaked electrified carrier is pressed to the surface. Since elasticity is obtained by blending the plastic resin, the surface is prevented from being cracked, as a result, the flaw is restrained. The acrylic whose functional number is smaller than the acrylic in the surface layer and butadiene acrylonitrile being plasticizer are exemplified as the plastic resin used in this case.

Filed: 1995-02-17
Abstract: PURPOSE: To reduce the arithmetic quantity when the offset amount of a masking reference curve is calculated and to improve the sound quality for higher satisfaction of the acoustic psychology. CONSTITUTION: An acoustic psychology analysis part 3 calculates the power spectrum of an audio signal from an orthogonal conversion factor, calculates the auto-correlation of the power spectrum for every band that is previously decided, and then calculates the offset amount of the acoustic psychological masking effect from the ratio between the maximum and minimum auto- correlation value. Based on this offset amount, the quantization bit number is decided for every sub-band of a quantizing/coding means 4. Then a 2nd necessary SN ratio is calculated from the signal power of every sub-band by means of a root-mean-square error minimum theory including the acoustic control, and the final necessary SN ratio is calculated by giving weighting to the 1st and 2nd SN ratios. Based on the final SN ratio, the quantization bit number is decided for every sub-band of the means 4.

IPC: H04L47/43
Filed: 1989-03-06
