IPC: H02M7/48
Filed: 1980-09-08
Abstract: PURPOSE:To prevent the hunting of a motor by feeding back a value corresponding to variation of the low frequency in the output current of an inverter to a voltage frequency converter determining the output frequency of the inverter. CONSTITUTION:An output of a pulse width modulation voltage type inverter 14 is applied to an induction motor 6 by way of a current transformer 5. A command frequency reference from a frequency setting device 7 and an output voltage of the inverter 14 are applied to a voltage controlling circuit 10 to form a voltage control signal, which is applied to a pulse width modulation controlling circuit 11. A load current detection signal from the current transformer 5 is inputted into an arithmetic circuit 13 with the command frequency reference through a phase inverter 12. The arithmetic circuit 13 react to variation in a low frequency of said detection signal but not to that of a high frequency. The output of the circuit is converted into or frequency control signal with a voltage frequency converter circuit and applied to the pulse width controlling circuit 11.

Title: Communication system for decentralized computer system
Inventor: OKAZAKI TAKU
IPC: G06F15/16
Filed: 1986-05-29
Abstract: PURPOSE:To attain mutual consensus among all computers with half the number of total messages regardless of the presence or absence of fault by adding the name of a computer that originates a message and the name of a computer to which the message has been transmitted to the message. CONSTITUTION:By transmitting the message from one computer 5i to other computers 5j through a communication circuit 6k, the name of the computer that originates the message and the name of the computer to which the message has been transmitted are added to the message in order to obtain the mutual consensus among the computers 51-5n. The computer 5j, receiving the message, prevents the computer 5i added to the message from being broadcasted. Thus the computer receiving the message need not to transmit the message to the computer added to the message, whereby the number of messages to obtain the mutual consensus can be substantially reduced.

Title: Magnetostriction measuring member
Inventor: SHINOHARA MIKIYA
IPC: G01L3/10
Filed: 1992-05-18
Abstract: PURPOSE:To obtain a magnetostriction measuring member which has large accepting torque and shows high sensitivity to the magnetostriction by providing a specific band-shaped thick layer in the outer periphery of a steel shaft material made of carbon steel or alloy steel. CONSTITUTION:The magnetostriction measuring member uses a steel shaft material made of carbon steel or alloy steel. For the carbon steel, SC material, S-CK material, etc., is employed. For the alloy steel, e.g. SCr material, SMn material or the like which is a kind of steel for mechanical structure is used. A band-shaped thick layer formed of Fe-Al alloy containing 1-50wt.% Al is provided on the surface of the shaft material. If the content of Al is too small, the hysteresis is greatly varied when the torque is detected. Therefore, the content, of Al is set to be not smaller than 5wt.% Moreover, if Al is contained too much, the sensitivity is lowered, and therefore the content should be 15wt.% or lower so as to increase the detecting sensitivity. When the band-shaped thick layer is too thick, it cracks, and therefore, the band-shaped layer is 3mm thick or thinner. Further, if the layer is too hard, it also generates cracks, and therefore the layer is adapted to have Vickers hardness Hv=420 or smaller.
