Filed: 1982-03-26
Abstract: PURPOSE:To permit 3-phase/2-phase conversion without using an operational amplifier by a converter wherein windings for respective phases on the secondary side of an insulated transformer are connected in series. CONSTITUTION:Windings for respective phases on the secondary side of an insulated transformer 5 are connected in series. One of the connection points is grounded to assume the reference potential. Interphase voltage VST between the S phase and the T phase is directly taken out as one voltage V  of 2- phase AC voltage. Then, the sum (VRS+BRT) of interphase voltage VRS between the S phase and the R phase and interphase voltage VRT between the T phase and the R phase is taken out. This summed voltage is divided in a resistance circuitry 6 for dividing by a resistor with a resistance value of 3-1 R and a resistor with a resistance value of R, thereby to obtain voltage of (VRS+VRT)/ 3. Thus obtained voltage is used as the other voltage V  of 2-phase AC voltage.

Filed: 1990-02-28
Abstract: PURPOSE:To stably convey sheets of paper and prevent a jam in an image forming device by providing a freely turning roller-shaped member in a position in which it will not disturb attraction of a cut medium, as in the opening of a guide plate. CONSTITUTION:A roller 42 has a pulley portion integrally therewith and an endless belt 51 wound around the pulley portion. When a photosensitive drum 25 is rotated in the direction indicated by the arrow E, the roller 42 is rotated via the belt 51 in the direction indicated by the arrow F at the same peripheral velocity as that of the photosensitive drum 25. During rotation of the roller 42, three holes 45 are constantly opposite to an opening 47. Therefore a peeling roller continuously exerts an attracting force on a cut sheet of paper 28 by means of its negative pressure source 23 and rotation of the roller 42 continuously exerts a conveying force on the paper 28. Hence the paper 28 is surely peeled from the photosensitive drum 25 even when the speed at which the paper 28 is conveyed and that of rotation of the photosensitive drum 25 are higher than usual.
