Title: Dwell time controlling process in igniter for internal combustion engine
Inventor: OKAMOTO OKIMICHI
IPC: F02P3/045
Filed: 1980-11-11
Abstract: PURPOSE:To make dwell time adjustable with change of shift rate in such a way that at the same time as input signals from a crank angle sensor of an igniter are added into an integrating circuit, output from the integrating circuit is shifted together with inversion of input signals. CONSTITUTION:When input signal ''1'' from a crank angle sensor 10' stands at H level, a transistor T1 is turned to the ON condition, non-inversion input terminal + of an OP amplifier OP1 becomes L level. Then, output ''3'' in which the signal ''1'' has been integrated can be obtained by measn of an integrating circuit which comprises the OP amplifier OP1, a resistor R1 and a capacitor C1. Then, output ''5'' from a level discriminating circuit which comprises an OP amplifier OP2 and resistors R2, R3, R4 becomes H level, and a transistor T2 is turned to the ON condition. Such as this, time constants in the integrating circuit are changed by controlling for ON/OFF on the current of the primary coil 4 in the ignition coil. Since the time constants in the integrating circuit are not changed even if the input signal ''1'' is applied as input with any cycle, dwell time can be adjusted.

Title: Image forming device
Inventor: ITO MASAHIRO
IPC: G03G15/01
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of the size and cost, to prevent a retransfer phenomenon and to always attain stable image output by applying an electric charge having the same polarity as that of a visible image, when passing through a charge applying means before visible images of each color are transferred and before the visible images are peeled from a member by which an image is received. SOLUTION: For preventing a retransfer during a multiplex transfer it is good enough for a triboelectric charge after being transferred onto a transfer material to be high, before the next transfer is performed, to prevent the polarity of the charge from being opposite because of a peeling discharge in the case of performing the next transfer. Then, the transfer material P after a magenta image is transferred for instance is moved in a state where the transfer material P is carried on a transfer sheet 5f, to a downstream position in a rotational movement direction from a transferring part, in accordance with the rotation of a transfer drum and reaches a position just under a separating electrified 5h. At this point, the charge is applied to magenta toner Tm by a negative DC discharge. Thus, it is constituted so that the multiplex transfer is performed while the triboelectric charge is prevented from being reverse, not to cause the retransfer and a deterioration in the image, reduction in density, etc.
