Title: Manufacture of nickel-based ferrite
Inventor: KOBAYASHI KEIICHIRO
IPC: H01F1/34
Filed: 1989-07-31
Abstract: PURPOSE:To use the raw material of nickel other than nickel oxide at a low cost and to make it possible to manufacture nickel-based ferrite characterized by a low cost and excellent quality by using nickel hydroxide as the raw mate rial of the nickel. CONSTITUTION:This is a method for using nickel hydroixe as the raw material of nickel. The nickel hydroxide contains only one more molecule of water in comparison with nickel oxide. Therefore, the effect of the change in raw material on the manufacturing process is less in comparison with a method using other raw material of nickel. For example, when nickel chloride is used, chlorine gas is generated in baking. Therefore, large-scale changes in manufactur ing apparatuses such as expansion of exhaust devices and the large-scale change in baking conditions are required. When the nickel hydroxide is used, however, only steam is generated. Thus nickel-based ferrite can be obtained without any change in conventinal manufacturing apparatuses using the nickel oxide.

Title: Dc motor controller
Inventor: ABE KIKUO
IPC: H02P7/298
Filed: 1989-07-31
Abstract: PURPOSE:To enable smooth power recovery restarting operation without giving disturbance at the time of recovery from power failure by using the actual number of revolutions of an motor in place of a speed set value when starting the speed control on the side of an armature, and changing the actual speed set value, using an acceleration limiting circuit, from this number of revolutions of the motor to the essential speed set value. CONSTITUTION:When it recovers from power failure, a signal PSF becomes 1, and further when the difference between a field current set value FREF and a field current value If becomes below the set value, the output of a comparator 7 becomes 1, and the output RN of an AND arithmetic unit 6 also becomes 1, and a speed control circuit 12 starts the speed control. Furthermore, by the control signal RN becoming 1, the actual speed reference NREFA is changed over to the output from an acceleration limiting circuit 3 at the time of power recovery. Moreover, at the moment when the control signal RN becomes 1, the input of the acceleration limiting circuit 3 at the time of power recovery is turned once to motor speed N, and then its speed set value FREF.

Abstract: PURPOSE:To realize fixed rotational speed regardless of a temperature change by setting reference voltage by a synthetic voltage value of voltage having no temperature characteristics and voltage having negative temperature characteristics. CONSTITUTION:A control IC 4 compares back electromotive force Va generated in a DC motor 2 by revolution and reference voltage VrefT by a comparator 18, and adds voltage difference generated by the comparator 18 to a transistor 20 for control and a transistor 22 for drive. Reference voltage VrefT is set by the synthetic value of first reference voltage Vref1 having no temperature coefficient and second reference voltage Vref2 having a negative temperature coefficient offsetting the temperature characteristics of the DC motor 2. In this case, the synthetic ration of reference voltage Vref1, Vref2 is adjusted, and the temperature coefficient offsetting the temperature coefficient of the DC motor is set by the synthetic value.
