Filed: 1995-01-13
Abstract: PURPOSE: To stick developer to releasing agent transferred and stuck to a transfer material carrying member, to easily remove the releasing agent, and to prevent the releasing agent from being transferred and stuck to an image carrier by transferring a visible image having specified density on the transfer material carrying member after forming the image of a second side based on a result obtained by comparing the integrated value of the image signal of a first side with a reference value in the case of double-sided image forming. CONSTITUTION: In the case of double-sided image forming, the image of the first side is transferred on a transfer material 48, and the transfer material 48 on which a toner image is transferred is separated from a transfer belt 310 and carried to a fixing device, where the toner image is fixed and turned into a permanent image. The residual toner left on a photoreceptor drum 301M after transfer is removed by a cleaner 305M thereafter. The digital signal of an electrostatic latent image on the photoreceptor drum is counted as a method for calculating the amount of the toner on the first side of the transfer material. When the counted number is larger than a specified value, it is judged that oil sticks to the transfer belt, and the toner image is transferred on the transfer belt at a specific timing so that the oil is easily removed.

Title: Decentralized control system
Inventor: SAKAMOTO HIDEYUKI
IPC: G06F1/00
Filed: 1987-01-30
Abstract: PURPOSE:To always set an accurate time point with each processor by providing a timer which counts the time to each processor together with a time setting/ transmitting means which performs the transmitting operation to each processor for time setting jobs when said timer is set under a time-up state. CONSTITUTION:The different time points T1-Tn are set at a time counting timer for each processor. The time of a clock 11 of each processor is set by the time setting communication that sets the time points at the prescribed time intervals. The timer 12 of each processor counts the time during which the time setting communication is discontinued. If this measured time value is larger than the time value set previously (time-up state), it is judged that a processor which so far performed a time setting action has a trouble. Then a time setting/ transmitting means 14 of the processor having a timer set under a time-up state performs the time setting communication. In such a way, an accurate time point can always be set by each processor.

Title: Encoder
Inventor: SUZUKI YASUMASA
IPC: H02P29/00
Filed: 1988-01-29
Abstract: PURPOSE:To decrease the jitter of an encoder output by averaging an output containing the jitter of a pulse generator by using a counter A, a phase comparator, a low-pass filter, a voltage control oscillator and a counter B. CONSTITUTION:A pulse generator 2 generates a pulse being proportional to a moving distance of a movable part 1. A counter A3 brings an output of the generator 2 to 1/16 frequency division, and a counter B7 brings an output of a voltage controlled oscillator 6 to 1/4 frequency division. Outputs of the counter A3 and the counter B7 go to inputs of a phase comparator 4, and the compara tor 4 outputs a voltage being proportional to a phase difference of this input. The voltage being proportional to this phase difference passes through a low- pass filter 5 and applied to an input of the votlage controlled oscillator 6. In such a way, even if a fitter is contained in the output of the generator 2, it is brought to 1/16 frequency division by the counter A3, and it is brought to 4-multiply by the oscillator 6, therefore, an encoder output scarcely having jitter, which is averaged can be obtained.
