Title: Image forming device
Inventor: HORIUCHI EI
IPC: G03G15/16
Filed: 1990-02-28
Abstract: PURPOSE:To prevent the occurrence of a transfer deviation in the vicinity of the rear edge part of a cutform sheet by specifying the carrying speed of a carrying means ejecting the cutform sheet from an image carrier with respect to that of a carrying means feeding the cutform sheet to the image carrier. CONSTITUTION:This image forming device is provided with an endless belt-like image carrier 10, toner image forming means 12 and 13 forming a toner image on the image carrier 10, a corona electrifier 14 transferring the toner image to the cutform sheet under non-contact state, the carrying means 32 to feed the cutform sheet PP, and the carrying means 33 and 51 to eject the cutform sheet PP. When the peripheral speed of the image carrier is defined as V, the carrying speed of the carrying means 32 is defined as V1, and V = V1 is defined, the carrying speed V2 of the carrying means 33 and 51 is set so as to be V2 = 1.010V1 - 1.018V1. Therefore, when the rear edge of the cutform sheet is removed from the carrying means 32, it is released from the locked state of the carrying means 32, and the cutform sheet can be carried at the carrying speed of the carrying means 33 and 51. Thus, delay in feeding and the transfer deviation do not occur.

Filed: 1981-03-31
Abstract: PURPOSE:To enable stable control of combustion even at the time of switching a set voltage in response to a flame detection signal by set voltage switching means in a combustion controller of a proportional combustion system by  employing a semiconductor switching element instead of a relay contact as the switching means. CONSTITUTION:Transistors Q1, Q2 are controlled only when they receive flame detection signals F, F' which are generated by flame detectors (not shown), and when an ignition operation is performed, both the transistors become ON. At this time a power source voltage is applied through resistors R6, R7 via the first setting circuit as the first set voltage to an amplifier 1, and the output signal of a level adapted for the ignition operation is produced from an output terminal 2. On the other hand, when the flame signals F, F' are inputted and the transistors Q1, Q2 become OFF, the second set voltage set via a variable resistor VR1 is applied instead of the set voltage to the input terminal of the amplifier 1, and the output signal of the level adapted for the ordinary combustion is produced from an output terminal 2.
