Title: Overcurrent protective circuit
Inventor: KOBAYASHI KAZUO
IPC: H02H9/02
Filed: 1989-11-20
Abstract: PURPOSE:To maintain the potential difference between input and output small by connecting a high resistance, a PMOS-FET, and an NMOS-FET in series between the gate and the source of a MOS-FET for control of the current between an input terminal and an output terminal, and then connecting a MOS- FER for amplification in parallel with this. CONSTITUTION:An error amplifier 5 compares output voltage (in the one shown in the figure, the voltage divided by resistances 6 and 7) with reference voltage, and it controls the gate voltage of a MOS-FET 8 for current control, according to the change of the output voltage, and maintains the output voltage constant. When the voltage enough to put the FETs of P1, P2, N1, and N2 in on condition is applied between the source and the gate (between A and B) of the MOS-FET 8 for current control, a current flows between A and B, and a potential difference arises between both ends of high resistance R1, and if this potential difference exceeds VTH of MOS-FER for amplification of P3, the FET of P3 becomes on conditions, and the current flowing between A and B increases suddenly. Hereby, the voltage applied between the source and the gate is restricted, so overcurrent can be prevented.

Title: Discharge position detector for ink jet
Inventor: YONEDA SATORU
IPC: B41J2/125
Filed: 1988-11-28
Abstract: PURPOSE:To prevent quality of an image from decreasing due to deviation of printing by providing a plate which is deflected upon collision of ink jet, detecting the deflected amount of the plate, detecting and regulating the reference position of an ink jet nozzle. CONSTITUTION:The bent of a thin plate 131 is detected by a sensor 53 while discharging ink jet from a nozzle 41. When the plate 131 is bent, a motor 63 is reversely rotated, and the ink jet is once removed from the plate 131 to prevent the ink jet from rising as a droplet. Then, whether the plate 131 is bent or not is again detected, and when the bent of the plate 131 is detected, the motor 63 is immediately stopped in next step. As a result, since the lateral fine adjustment of the nozzle 41 is conducted, it can prevent the positional deviation and fog of a print.

Title: Lock protection circuit for motor
Inventor: INOUE TOMOHIRO
IPC: H02P7/288
Filed: 1990-11-05
Abstract: PURPOSE:To prevent smoking, ignition by freely setting a locking time by the capacity of a capacitor and the current value of charging/discharging in an abnormal state at the time of abnormal state of motor locking, and controlling ON, OFF a current flowing to a motor. CONSTITUTION:If a motor 1 is locked, a torque command voltage is lowered to operate in a direction for increasing a current flowing to the motor 1. However, when the voltage drop of a motor current detecting resistor 4 is increased to be larger than a reference voltage 6, the output of a first voltage comparator 5 is inverted, and an output of a high level is output. Accordingly, a drive amplifier 9 is controlled at a motor current by the output of a voltage comparator 5, and the voltage drop of the resistor 4 is stabilized at the same level as the voltage 6. Further, since the output of the comparator 5 is applied to the base of a transistor 10 through an inverter 18, the transistor 10 is turned OFF. When the capacitor 11 is charged to be higher than a reference voltage 14, its output is inverted, and a motor current is cut OFF.
