Title: Driving system for step motor
Inventor: NAGABORI YUKIHIRO
IPC: H02P8/00
Filed: 1978-10-27
Abstract: PURPOSE:To reduce the vibration at the time of rotor stop and enhance motor efficiency by supplying a driving current, having a pulse-wave form which decreases at a specified slope form after rising, to the exciting coil of a step motor. CONSTITUTION:When a switching circuit 7 is turned on by a control pulse signal, the charges stored in a capacitor C is flown to an exciting coil 2. In this case, if a current IZM that flows through the exciting coil 2 at the time of application of a rated voltage VZ is greater than a voltage-retaining current IZ that is determined by a Zener diode D2 and resistor R at the rated voltage VZ, both the current from the capacitor c and the current from a battery 5 flow. On the other hand, since the driving current decreases gradually in a waveform as shown in the Figure due to the decrease in the capacitor voltage and the high impedance of the Zener diode D2, the vibration of a rotor is reduced in a short time.

Title: Electric water heater
Inventor: TAKETSU SHINJI
IPC: H02H9/04
Filed: 1984-06-27
Abstract: PURPOSE:To prevent the malfunction of a leak breaker due to a surge generated in an electric source line by a method wherein the surge is absorbed before the surge, generated in the electric source line, passes through the leak breaker. CONSTITUTION:The surge, generated in the AC 100V electric source line 10, passes through first over-current relay 8 and arrives at the electric circuit 16 of the electric water heater. However, the surge between lines is absorbed by first surge absorbing element 12 of a surge absorbing circuit 17 and the surge between the line and ground is absorbed by second surge absorbing element 13 before the surge passes through the first leak breaker 5. Accordingly, the malfunction of the first leak breaker 5 will never be caused since the surge is absorbed before the first leak breaker 5. On the other hand, the surge between lines, which is generated in AC 200V electric source line 11, is absorbed by the third surge absorbing element 14 of the surge absorbing circuit 17 and the surge between line and ground, generated in the same electric source line 11, is absorbed by the fourth surge absorbing element 15 before the surge, generated in the same line 11, passes through the second leak breaker 6.

Title: Image sensor
Inventor: KADOMA AKIRA
IPC: H04N5/374
Filed: 1988-05-31
Abstract: PURPOSE:To obtain a high performance image sensor by providing a switching transistor(TR) for a reset circuit between the base of a phototransistor and constant negative potential in addition to a phototransistor array and the switching TR for controlling a charging current to the array. CONSTITUTION:A complementary signal is inputted from a terminal 14, and a block select signal is inputted to the terminal 15. After the switching TR 23 is turned on by a scanning signal and a video signal is read, the switching TR 27 is turned on by a reset signal R while the TR 23 is left being turned on. As the result, the uncharged part of the phototransistor 25 at the time of read can be additional-charged (reset), and the read free from a residual image portion can be secured at the time of the next scanning. Since a current flows from the base of the phototransistor 25 to the negative potential VEE through the switching TR 27 at the time of additional charge, charging speed is so high that the interCB capacity of the TR 25 can be high speed charged nearly perfectly, and the high speed and high resolution image sensor with less residual image is obtained.
