Title: Temperature controller for fixing device
Inventor: KUMON TOSHIHIKO
IPC: G03G15/20
Filed: 1987-09-09
Abstract: PURPOSE:To preclude a fixation detect and an offset as much as possible by turning off a rotary driving means at a constant time after the start of temperature control and turning off a heating means when a 2nd set temperature high than a 1st set temperature is reached. CONSTITUTION:The initial surface temperature of a heat roller 22 is detected by a temperature sensor 24 and when the temperature of the heat roller 22 is lower than the 1st set temperature T1, a timer clocks prescribed time; when the timer finishes clocking the time, a rotation signal S3 is turned off and the heat roller 22 and a pressure roller 23 stop from rotating. When the temperature reaches the 2nd set temperature T2, the rotation signal S3 and a heating signal S2 are turned off and the temperature control is finished. Consequently, the warming-up time up to the end of the temperature control becomes short and the surface temperature becomes high and uniform enough not to cause the fixation defect, so the fixation defect is precluded to prevent the occurrence of the problem of picture quality as much as possible.

SOLUTION: When a paper 1 passes selectively through the intermediate fixing device 5b and the inversion device 15b from the printing devices 10a and 10b and flows to the terminating fixing device 4 through the printing devices 10c and 10d, a previously printed two-color image transferred on one surface of the paper 1a traveling between photoreceptor drums 11a and 11b and transfer devices 12a and 12b is immediately heated by the fixing device 5b and fixed on the traveling paper 1a. Thus, the printing surface is not stained even when it is brought into contact with a roller and the like. When the printing front and back surfaces of the paper 1a is inverted by the inversion device 15b and passed through the next printing devices 10c and 10d, a subsequently printed two-color image is transferred and fixed by the fixing device 4.  Then, it is cut and a printed matter having a front surface printed in two colors and a back surface printed in two colors is ejected.

IPC: H03K17/785
Filed: 1983-11-30
Abstract: PURPOSE:To shorten the OFF time of an output TR by discharging charge applied at the ON of an FET through a bipolar TR connected between the source and drain of the FET in parallel. CONSTITUTION:A diode is used for a photovoltatic element 1, the charged capacity of the bipolar TR4 is sufficiently low as compared to that of an FE type output TR2 and the threshold voltage of the base is lower than that of the TR2. When light is interrupted, the capacity stored in the TR4 starts to be discharged. The discharged current flows through the diode 1 at first, but positive voltage is applied to the base of the TR4 because a diode 5 exists, the TR4 is turned to the connected status and the charge of the TR2 acted as a capacitor is discharged through the TR4. The time from the start of the discharge of the TR2 to the ON of the TR4 is shortened and the charge of the TR2 is discharged through the diode 1 and the TR4.

Abstract: PURPOSE:To improve the operability by alternately executing document transmission from this side and document reception from the other party side and eliminating the need of redialing at the time of response to contents of the received document. CONSTITUTION:Documents are set on the caller side and the caller side, and a polling mode key 48 on the calling side is depressed to set the normal polling mode, and the FAX number of the caller side is dialed by ten keys 40. The caller side transmits one document to the caller side in response to the polling request from the caller side. It is detected whether the calling side has documents to be transmitted or not by a next page sensor 22; and if the caller side has documents to be transmitted, the caller side transmits one document to the caller side after issuing a message indicating the presence of documents. The caller side discriminates whether the calling side has documents to be transmitted or not; and if it has, the caller side receives one document from the calling side. It is discriminated whether the caller side has documents to be transmitted or not; and if it has, the caller side is returned to the original state after issuing the message indicating the presence of documents. If it does not have, the processing is terminated. The calling side judges whether the caller side has documents to be transmitted or not; and if it has, the calling side is returned to the original state. If it does not have, the processing is terminated.
