Title: Image forming device
Inventor: ONO AKIO
IPC: G03G15/01
Filed: 1995-03-10
Abstract: PURPOSE: To obtain a color image free from color slurring by forming plural register marks in a ratio of one mark for every half the rotation of an image carrier and executing a register correction based on the mean value of plural pieces of readable data. CONSTITUTION: In every image forming station, plural register marks 9 and 10 are formed on a carrying belt 7 in a ratio of one mark for every half the rotation of each photoreceptor drum 1C, 1M, 1Y and 1BK. The position of each register mark 9 and 10 is separately detected by each mark detector 11 and 12. In the case an unreadable mark exists in plural register marks, a couple of data is invalidated. Also the mean value of plural remaining valid register data is obtained, then, the register correction is executed by the mean value. Thus, the error of the register data due to the rotating speed fluctuation of the photoreceptor drum is cancelled.

Title: Disk device
Inventor: HASHIMOTO TOSHIKAZU
IPC: G11B21/08
Filed: 1983-05-04
Abstract: PURPOSE:To enable to normally drive a motor against a jitter by supplying a pulse to a drive circuit through a delay circuit. CONSTITUTION:Since a latch signal outputted at an interval shorter than a time capable of following up a stepping motor is latched to a latch circuit 1, its output line 51 becomes H state. However, this H signal 53 is in L state since a gate 2 is closed while the output 52 of a delay circuit 4 is in L state, and is not applied to a delay circuit 3. When a delay circuit 4 calculates the prescribed period (28 msec.) from the delivery of a pulse from the delay circuit 3, the output 52 again becomes H state, and the gate 2 is opened. In this manner, the H signal latched to the circuit 1 is applied to the delay circuit 3. Accordingly, a drive circuit 20 can deliver a pulse of the inverter capable of following up by the stepping motor.

Filed: 1978-06-28
Abstract: PURPOSE: To continually keep the potential of input signals for conducting a  MOS.FET constant, by forming a bias circuit so that bias value change in the same  manner as the variation of threshold voltage.  
     CONSTITUTION: The potential of a joint 19 is brought to potential near threshold voltage from the I-V characteristics of a MOS.FET 17, which short-circuits a gate and a drain, and a load curve of a resistance 18. The potential is divided by means of resistances 15 and 16. A gate of a MOS.FET 12 has voltage lower than threshold voltage, and is biased to adequate value near approximate threshold voltage. When threshold voltage changes from fixed value, the potential of the joint 19 also alters in response to the change of the threshold voltage. Thus, the potential of input signals for conducting the MOS.FET 12 does not depend upon the dispersion of threshold voltage.
