Patent JP-H04177904-A (JP)
Title: Signal detection system and circuit thereof
Inventor: KURASAWA KAZUO
IPC: G01S7/48
Filed: 1990-11-09
Abstract: PURPOSE:To increase an average level of each period of a DC output and to attain high detection rectification efficiency by shifting a level of an AC input so that a bottom or a peak of the AC input comes to a zero level and converting the input into the DC output. CONSTITUTION:When a level of an AC input IN reaches a bottom level, a clamp pulse CP rises, a clamp switch 34 is closed, an output terminal of a capacitor 33 connects to ground, reset the capacitor 33 is charged by a difference between a bottom potential at a preceding waveform and a ground level, and an output OUT reaches the zero level. Then the clamp pulse CP falls down in a short time and when the clamp switch 34 is turned off, since the output level of the capacitor 33 is changed in response to a change in the AC input, the DC output OUT shows a waveform in which the AC input IN is shifted. Thus, a mean level of each period of the DC output is increased to improve the rectifier efficiency.

Abstract: PURPOSE:To increase torque and the speed of a motor by stopping feed to A phase and B phase from a DC power only in a section, in which armature currents exceed a set value and are lowered up to a specified value, and discharging magnetic energy stored in an armature coil through a diode during stoppage. CONSTITUTION:When exciting currents exceed a set value by the reference voltage of a terminal 40, an output from an AND circuit 43a is brought to a low level because an output from an operational amplifier 40a is brought to the low level, and a transistor 20a is not conducted. Consequently, magnetic energy stored in an armature coil 17a is discharged through a diode 21a, a transistor 20b and a resistor 22a. When discharge currents are lowered up to a specified value, an output is returned to a high level by the hysteresis characteristics of the operational amplifier 40a, the transistors 20a, 20b are conducted again, and armature currents are increased. When discharge currents are elevated up to said set value, the output from the operational amplifier 40a is brought to the low level, the transistor 20a is changed into non-continuity, and armature currents are lowered.
