    摘要: An electrophotographic developing roller in which air tightness and electrical conductivity in a fit section between a cylindrical metal base body and a metal flange are satisfactory and outside diameter deflection accuracy is satisfactory; and an electrophotographic developing roller which is relatively inexpensive, excellent in mechanical rigidity, surface processability and plating film formation (corrosion resistance) and capable of being satisfied with a prescribed dimensional accuracy are provided. The electrophotographic developing roller is a developing roller having a cylindrical metal base body and a metal flange. The metal flange has a larger diameter section to be fitted in the opening end inner surface of the cylindrical metal base body and a smaller diameter section serving as a central shaft body coaxial with the cylindrical metal base body. The fit section surface of the larger diameter section before being press fitted has an uneven shape such that a maximum surface roughness Ry due to a circumferential groove formed by cutting processing is from 25 μm to 70 μm.

    摘要: A drive current and a regenerative current are alternately applied to a motor during a PWM (pulse width modulation) time period. The regenerative current is produced by an electromagnetic induction of an armature and flows in the opposite direction as the drive current. Therefore, a rotating speed of the motor is reduced, so that a speed-reduction following characteristic for the motor is improved. By varying the duty factor, the lengths of time during which the drive current and the regenerative current are flowing can be controlled. Thus, the speed of the motor can be controlled.

    摘要: A balance mechanism of an industrial robot is provided with a first balance mechanism for a first arm which is swingably mounted to a stand of the robot and a second balance mechanism for a second arm which is swingably mounted to a distal end of the first arm. The first balance mechanism includes a flexible coupling device such as, for example, a chain, led through a guide, which couples between a coupling element of a coupling member which is mounted to a center of angular movement of a proximal end of the first arm and a spring having one end fixed to the stand and which is moved in the direction of deformation when the first arm is angularly moved. The second balance mechanism includes a counterbalancer disposed in the opposite side to an operation side of the second arm and a center of angular movement of the second arm constitutes a fulcrum. The balance mechanisms can be applied to the robot without exchanging parts greatly even if the robot is installed in any position.
