  • Patent number: 6846102
    Abstract: In an agitating machine, an axial direction of a drive roll is inclined to one side or another side with respect to an axial direction of a guide shaft which is rotated on its own axis, whereby a drive support machine casing and a driven support machine casing are moved to one end side or another end side of the guide shaft. When an arrival detecting apparatus detects that the drive support machine casing or the driven support machine casing has reached the one end side or the another end side of the guide shaft, a control apparatus drives a reversing motor so as to incline the axial direction of the drive roll to the another side or the one side. Since the arrival detecting apparatus, the reversing motor and the control apparatus are electrically driven, it is possible to securely incline the axial direction of the drive roll.

  • Patent number: 4945021
    Abstract: The present invention relates to a photosensitive member containing a specific bisazo compound described by general structural formula[I] and formed on an electrically conductive substrate; ##STR1## Wherein X is a hydrogen atom, halogen atom, alkyl radical, alkoxi radical, nitro radical or cyano radical; A is a diatomic radical selected from among the following: ##STR2## B is a coupler described by formulae [II] through [VI]; ##STR3## R is a hydrogen atom, halogen atom, alkyl radical, alkoxi radical, nitro radical or cyano radical; and Y is an aromatic carbocyclic residue or aromatic heterocyclic residue, each of which may have a substituent; G is a carbamoyl radical or sulfamoyl radical and may have a substituent; R.sub.1 is a hydrogen atom, alkyl radical, amino radical or carbamoyl radical, each of which may have a substituent, a carboxyl radical or cyano radical; M is an aryl group which may have a substituent, which is improved in photosensitivity and dispersibility.

  • Patent number: 4871633
    Abstract: The present invention uses an azo pigment having in the center of an N-oxide heterocyclic structure as a photoelectrical charge-generating material. The pigments are excellent in dispersion stability in a dispersed solution, and enable the provision of a photosensitive member excellent in sensitivity properties.
