摘要： An image forming apparatus includes a plurality of image bearing members for bearing an image of plural colors, respectively, an intermediate transfer member and a controller for controlling the peripheral speed of the transfer member. For this apparatus, selection is made possible between a first mode of sequentially transferring the image of plural colors onto the intermediate transfer member by use of the plurality of image bearing members for the transfer of the image of plural colors on the intermediate transfer member to a transfer material, and a second mode of transferring a monochromatic image onto the intermediate transfer member by use of a predetermined image bearing member for the transfer of the monochromatic image to a transfer material. When the second mode is selected and the length of the monochromatic image in the moving direction of the intermediate transfer member is shorter than the distance from a first position of transferring the monochromatic image on the predetermined image bearing member onto the intermediate transfer member to a second position of transferring the monochromatic image on the intermediate transfer member to the transfer material in the moving direction of the intermediate transfer member, the controller switches the peripheral speed of the intermediate transfer member from a first speed of transferring the monochromatic image from the image bearing member to the intermediate transfer member to a second speed higher than the first speed during a predetermined time period.

摘要： This invention discloses an output circuit in an integrated circuit. This invention includes first and second MOS transistors and a drive and control circuit. The first and second MOS transistors are connected in series between Vcc and Vss power source nodes, and receive complementary signals, respectively. When one of the transistors is OFF, and the other transistor is turned off from an ON state, the drive and control circuit moderately decreases a gate potential of the other transistor to a level at which a transconductance of the transistor which is turned off from an ON state is decreased to some extent. Thereafter, the drive and control circuit decreases the gate potential to a level at which the transconductance is sufficiently decreased.

摘要： In this invention, in a sensing circuit of a dynamic memory, barrier transistors are provided between the bit lines and the sensing amplifier. A circuit is provided that, on sensing and on data transfer, changes the gate potential of the barrier transistors so that during the sensing operation the barrier transistors are temporarily turned OFF, so that sensing can be carried out with high sensitivity, as the sensing system is not affected by the parasitic capacitance of the bit lines, while, on data transfer to the input/output lines, the gate potential of the barrier transistors is raised to a level greater than a value reached by adding the threshold value of the MOS transistors to the power source voltage, so that the conductance of the barrier transistors is increased, thereby speeding up the presensing of the input/output lines in the sensing circuit.
