    摘要: A picture image forming apparatus including a photoreceptor belt driven by a drive device, a plurality of developing devices for forming toner picture images on the photoreceptor belt, an intermediate transfer device, to a surface of which toner picture images on the photoreceptor belt are overlappingly transferred plural times when a picture image is to be formed on a single page, and a transfer roller for pushing a sheet against the intermediate transfer device in order to transfer toner picture images to the sheet. The intermediate transfer device is an intermediate transfer belt contacted by the photoreceptor belt to be driven thereby. A photoreceptor-side roller enables contact of the intermediate transfer belt and the photoreceptor belt, and the intermediate transfer belt is trained around the photoreceptor-side roller and a transfer-side roller for pushing the sheet against the transfer roller. A diameter d2 of the transfer-side roller is smaller than a diameter d1 of the photoreceptor-side roller.

    摘要: Conventional disk recording and reproducing apparatuses have addressed a shortcoming that they cannot correct squareness errors and misalignments caused by the warpage of a disk and the eccentricity of the center hole of the disk and of the center of curvature of signal tracks. To overcome this shortcoming, a disk recording and reproducing apparatus of the present invention comprises: magnetic bearing means capable of supporting a rotary body and adjusting a relative position of the rotary body; a pickup for irradiating, with a laser beam, a recording surface of a disk mounted on a table arranged on the rotary body and receiving the laser beam reflected by the recording surface; detection means for calculating a relative positional relationship between the disk and a focal position of the laser beam based on a signal from the pickup; and control means for adjusting the position of the rotary body by controlling the magnetic bearing means.

    摘要: A location-force target path creator creates a smooth target path function from target values among values of location, position, force and moment given for a force control system. The target values are set as nodes together with times for which the target values are applied. The nodes are projected onto a time axis having a time region which is divided into a series of time regions. A target path function is calculated for an element motion by applying a boundary condition to each of the time regions.

    摘要: A servo control apparatus for controlling according to a position command signal an object in a mechanical drive system having a position detector.A state observer is receptive of a drive torque signal and a position detection signal from the position detector for processing these signals to estimate concurrently a disturbance torque and velocity of the object to output an estimated disturbance torque signal and an estimated velocity signal.A position control processor is receptive of the position command signal, the position detection signal, the estimated disturbance signal and the estimated velocity signal for processing these signals to carry out positive feedback of the estimated disturbance torque signal and velocity feedback compensation by the estimated velocity signal to thereby produce the drive torque signal effective to control the object and to cancel out an actual disturbance torque generated in the object.
