Title: Apparatus for controlling speed of motor
Inventor: SAITO TOMOYUKI
IPC: H02P7/29
Filed: 1990-06-20
Abstract: PURPOSE:To improve a controllability in the case of a low speed and reduce the switching loss of a driving element in the case of a high speed, by providing the apparatus capable of switching over PWM frequencies to each other according to a rotational frequency or a load torque increasing or decreasing respectively. CONSTITUTION:When a rotational frequency is set high, a switch 25 is switched off, and an oscillation frequency is determined by a timing resistor 11 and a timing capacitor 12. Then, when a rotational frequency is set low, the switch 25 is switched on, and the oscillation frequency is set high. This frequency set high is determined by the timing capacitor 12 and the resistance value of the parallel circuit of the timing resistor 11 and a timing resistor 24. The resistance value of the parallel circuit comes less than the one of the resistor 11, and the oscillation frequency comes high. When the rotational frequency is set low, a PWM frequency is made to be high, and a controllability is made to improve. When the rotational frequency is set high, the oscillation frequency is made to be low, and the switching loss of a driving element is made to decrease, and thereby, its temperature rise is suppressed.

The drop-out detection signal is applied to one input of each of AND gates 56 and 58, and a signal obtained by inverting the output of a delay circuit 53 by an inverter 59 and the output of a delay circuit 53 are applied to the other inputs as they are. The output of the AND gate 56 controls switching of a switch 40, and the output of the AND gate 58 controls switching of a switch 32. Since the presence or the absence of drop-out is detected in the video signal, which has the time base corrected, and an alternate signal for compensation is taken from the signal which has the time base corrected in this manner, drop-out parts do not remain at all after drop-out compensation.

Title: Controller/monitor for distribution machinery
Inventor: ARINOBU ICHIRO
IPC: H02J13/00
Filed: 1988-06-30
Abstract: PURPOSE:To perform control without requiring a central controller/monitor or full knowledge of operational sequence or prohibition items by producing a control command from each terminal controller/monitor and transmitting the control command to another terminal controller/monitor thereby filling the role of a central controller/monitor. CONSTITUTION:An input section 3e in a terminal controller/monitor 3A detects the open/close state of the alarm contact of an earth leakage breaker (not shown) and provides open/close data to a monitor information producing section 3f. The monitor information producing section 3f produces monitor information based on the operational sequence of the earth leakage breaker stored in an operational sequence memory section 3s and the alarm open/close data. Furthermore, the monitor information producing section 3f produces a command word representing a 'report command' which is passed, together with the monitor information, to a transmitting/receiving section 3a through a report command producing section 3g and a code producing section 3i. The transmitting/receiving section 3a adds the self address set in a self address setting section 3j to the command word thus producing a transmission signal and interrupting a terminal controller/monitor 30.

Title: Corona separating method
Inventor: OGURA MASAAKI
IPC: G03G15/14
Filed: 1979-12-12
Abstract: PURPOSE: To ensure the steady separation of corona to prevent a jam, by varying the separating conditions according to the type of the transfer paper plus the factors such as the temperature, humidity and the like which affect the separation.  
     CONSTITUTION: The power source using both the AC and DC power sources is used for the isolating high-voltage power source which applies the voltage to the separating corona discharger 7. In this power source, the AC output of the high voltage generator HVG is converted to the appropriate voltage through the transformer T, and the voltage of the DC power source is turned to a fixed level of voltage via the constant voltage circuit VS to be applied to the capacitor C. The inter- terminal voltage of the capacitor C compounded with the AC output of the transformer T to be applied to the discharger 7. In general, the more the water content of the transfer paper the less the DC component of the separated current. And when the water content of the transfer paper increases, the separation enable range is reduced. In this connection, a humidity sensor is installed here to vary the bias voltage VB by the humidity, thus increasing the range of separation. In such way, the separating conditions is varied to ensure the steady separation of corona.
