Abstract: PURPOSE:To obtain phase and speed signals which change smoothly by setting amplitude comparing levels in the region corresponding to the phase errors of position detecting signals of two phases as well in addition to a 1/2 period near the central level of  amplitudes with respect to both of the position signals of two phases.

The  signal A is conducted to a comparator 5, where the signal is compared with the amplitude level of a setting circuit 3 for amplitude comparing levels. The amplitude comparing level sets the level in the part near the central level of the amplitudes among the  levels corresponding to the respective positions divided equally by 20 from the period  of the position detecting signal. If there is a change in said signal when the signal is  compared with a detecting circuit 24 for the change in the comparing signal, said circuit outputs a change detecting signal CHANGE A. If the change is in a + direction,  a change code UP A is outputted. The change detecting signal B is outputted as a  signal differing in the phase by a 1/4 period from a detector 2 and is subjected to  processing similar to that for the signal A, whereby the information in positions and  speeds is obtained.

IPC: B41J2/30
Filed: 1989-05-18
Abstract: PURPOSE:To achieve reduction of power consumption and making high speed of response with a wire dot by a method wherein electromagnetic energy uselessly accumulated after hitting of a dot wire is accumulated once in a capacitor, and excess energy is so returned to a power source that voltage of this capacitor is kept constant. CONSTITUTION:A comparator 24 and a clock CK are inputted. An output of an AND gate 26 is converted in level with resistances 28a, 28b and a N type transistor 27 to turn ON or off a P type transistor 29. Voltage HV or energy which exceeds a specific value returns to a capacitor 2 via a coil 36. Electric current due to energy accumulated in the coil 36 when the transistor 29 is shut off forms a closed loop via a diode 31 to be returned to the capacitor 2 late. When there is no coil 36, the energy is consumed by resistance of the system, and return to the capacitor 2 of the energy is decreased. Further, since a capacitor 21 is actuated as a Zener diode with less power consumption and voltage HV can be established at thoroughly high level, electric current due to electromagnetic energy when TR1 to TRn are shut off is made to disappear quickly. Therefore, a high speed response printer can be manufactured.
