摘要:
A plurality of developing devices or units are supported on a supporting member or turret which is rotatable to revolve the developing devices to move a desired developing device to a developing station where the developing operation is effected with the desired one of the developing devices. The developing devices are each provided with detecting elements for detecting the remaining amount of the developer or the concentration of the developer. The detecting elements are located at such a position that during the rotation of the supporting member the developer particles move with the rotation of the supporting member so that the detecting element is constantly cleaned by the moving developer.
摘要:
A color image forming apparatus wherein a plurality of developing devices or units are supported on a supporting member or turret which is rotatable to revolve the developing devices to move a desired one of the developing devices to a developing station where the developing operation is effected with the desired one of the developing devices so that a color image is formed. The presence, absence or the amount of the developer within the developing devices are detected. When the detection indicates that the toner is to be supplied into a developing device, the developing device is moved to a predetermined developer supplying position, and then is stopped so that the developing device is supplied with the developer at the developer supplying position.

A color image forming apparatus including an image bearing member movable along an endless path, on which color toner images are formed, a transfer material supporting member movable along an endless path for supporting a transfer material and conveying it to an image transfer position where the color toner images are superimposed and transferred sequentially to the transfer material. Also provided are a first driving motor for driving the image bearing member, and a second driving motor, separately provided from the first motor, for driving the transfer material supporting member. In addition, the apparatus includes a detector for detecting the speed of the surface of the transfer material, a discriminator for determining whether the speed variations detected by the detector are within a tolerable range, and a control, responsive to the discriminator, for stopping the operation of a subsequent image transfer step when the detected speed variation is beyond the tolerable range, and for repeating latent image forming, developing, and transfer steps.
摘要:
The present invention provides an apparatus wherein image fixing means is controlled for different fixing conditions under which a toner image is fixed on a recording material to adapt it to a synthetic resin sheet as the recording material or to a color image to be fixed, including at least one of fixing temperature, fixing speed and actuation of cleaning means. The present invention is particularly effective in use for a recording system in which the fixing temperature and speed are decreased and the cleaning means is actuated when a color image is to be formed on a transparent or resin sheet. The present invention is most useful for a color image recording system.
摘要:
A copying machine, or a similar image recording apparatus, does not terminate the image forming process, even when an abnormality in sheet transportation is detected, until the process is completed, and a sheet bearing the image prepared in this image forming process is transported after jammed sheets are removed, so that unnecessary waste of imaging sheets can be avoided.
摘要:
A relay (20) receives a battery information acquisition time from each battery module (10) and calculates measurement time differential information Δt, that is, a time difference between the battery information acquisition time as a reference and the battery information acquisition time of another battery module (10) among the received battery information acquisition times, for each battery module (10). A measurement time correction unit (115) of each battery module (10) corrects a measurement time by the measurement time differential information Δt, using the measurement time differential information Δt received from the relay (20) to adjust the battery information acquisition time of each battery module (10) to the same time.

A fuel cell detection device according to the present invention includes: a cell block formed with a plurality of cells serially connected to each other; a voltage detection element for detecting voltages of the cells within the cell block; and another voltage detection element for detecting a voltage of the operating power source of the voltage detection element, where the operating power source of the voltage detection element is supplied from a voltage of the inside or both ends of the cell block, and the operating power source of another voltage detection element is supplied from a voltage of the outside of the cell block, the operating power source of another voltage detection element being less variable than the operating power source of the voltage detection element.
摘要:
A turbine wheel of a turbocharger has a turbine blade. The turbine blade has a fin shape of which width in the rotation direction of the turbocharger is narrow, and is projected from the base portion of the turbine wheel. An inclined part of the turbine blade is inclined with respect to the rotation direction of the turbocharger. A coil is disposed so that the inclined part passes nearby as the turbine wheel rotates in a posture that an end in the center axis direction is directed toward the turbocharger. A detector detects a change in inductance, which occurs when the inclined part of the coil passes nearby.
