Title: Feed forward control method
Inventor: KOJIMA KENJI
IPC: F23N5/00
Filed: 1980-03-13
Abstract: PURPOSE:To ensure an effective correction for a shift of the response time of a subject to be controlled, by calculating the amount of the feed forward of a direct digital control DDC controller including the delay time adjusting parameter. CONSTITUTION:For a combustion furnace FUR, the temperature detection output PVT sent from the temperature detector DTT is compared with the temperature target value SVT by the temperature control meter TIC. And an operation is given to the deviation of comparison to obtain the correcting amount of the operation output MVA to the air flow rate control valve CVA. This correcting amount is added to the preceding operation output value and then sent to the valve CVA. In this case, the amount of feed forward FF is calculated for the next operation, and the coefficient showing the FF gain plus the delay time adjusting parameter alpha are included into the calculation mentioned above to obtain the operation output to the valve CVA. Thus an FF is possible in a comparatively short time for the correcting amount of the operation output MVF to the fuel supply control valve CVF. Accordingly a delay of the response time can be reduced to a change of the control signal.

Abstract: PURPOSE: To prevent unnecessary vibration when an actuator returns, by attaching to a support fram through a buffer such as rubber a holding member which supports one end of the actuator so that it can rotate.  
     CONSTITUTION: The same number of actuators 8 as electromagnets 7 are provided in an actuator block A so that the actuators correspond to hammers 3 and are driven by hammer drivers 20. A buffer 14 such as rubber is provided on the suppoted point of the actuator 8. A type drum 1 and a ratchet 2 are continuously rotated. The electromagnet 7 is energized synchronously with the rotation of the drum 1 to attract the actuator 8 toward the core 7a of the electromagnet 7 against a spring 11 and swing the actuator in the direction of an arrow X. As a result, a part of the driver 20 plunges into the rotation loci of the ratchet 2 so that the driver 20 to which an impact is applied swings in the direction of another arrow Y. At that time, the hammer strikes paper 45 on the drum 1 to cause printing.

Abstract: PURPOSE:To improve a durability of a contact point, enhance an energy consumption efficiency and eliminate a variation of noise by a method wherein the number of changing-over stages of an amount of air in a condensing air blower is set to more than three stages, a condensing temperature at each of the stages is made as a uniform value when an amount of air is decreased and in turn a condensing temperature of each of the stages is made as a different value when the amount of air is increased. CONSTITUTION:Control contact points S1 and S6 and a forced air blowing contact point SH are turned ON, a compressor 1, a condensing air blower 5 and an evaporating air blower 6 are energized and then a cooling operation is carried out under a forced air operation H. As a condensing air temperature (t0) is decreased, a condensing temperature (t1) is also reduced, and in case that it is less than a releasing temperature T1, the strong air contact point SH is turned OFF and a weak air blowing contact point S1 is turned ON to cause the condensing air blower 5 to be set at a weak air operation L. An amount of air of the condensing air blower 5 is changed over by three stages, a condensing temperature (t1) when an amount of air is reduced is set as the same releasing temperature at each of the stages, a condensing temperature (t1) at each of the stages is defined as T1 and a condensing temperature (t1) at each of the stages when the amount of air is increased is made as different releasing temperatures T2 and T3, a temperature difference between the releasing temperature T1 and the releasing temperature T3 can be increased and a repeating operation of releasing/ release at a short time is prevented.

Title: Speed controller for induction motor
Inventor: OOTSUBO OSAMU
IPC: H02P27/06
Filed: 1981-03-09
Abstract: PURPOSE:To reduce the capacity and the size of a control circuit and an induction motor by suitably controlling the output torque of the motor in response to the load of a rotor to be controlled. CONSTITUTION:After the voltage of an AC power source is full-wave rectified, a signal obtained by inverting the waveform of the voltage is applied to a terminal B. This input signal is biased via a resistor 45 by a resistor 46 and a capacitor 47, and is inputted to the base of a transistor (Tr) 48. Since the collector of the Tr 48 is connected to a controlled power source VSS through a resistor 49, the voltage of the collector becomes rectangular wave. When a rectangular wave voltage is applied to the base of the Tr 51 to cause the Tr 51 to be ON, the charge of the capacitor 54 charged by the power source VSS is discharged through the Tr 51, and the collector voltage is raised. Thereafter, when the Tr 51 is interrupted, the capacitor 54 is again charged by the power source VSS.

Layers 6 and 14 are sources, layers 10 and 12 are drains, and layers 7, 8, 11, and 13 are gates. The operation is the same as a conventional J-FET, but controlling the density and channel length as to layers 9 and 15 makes it possible to form both circuits with saturation characteristics and with unsaturation characteristics such as an electrostatic induction type circuit. In this way, a complementary type logic structure can also be formed, the power consumption can be reduced remarkably, and the high speed of the J-FET will not deteriorate by the logic structure.
