IPC: B66B1/30
Filed: 1993-06-15
Abstract: PURPOSE: To provide a variable-voltage variable-frequency induction motor for an elevator which does not need speed feedback. CONSTITUTION: On the occasion of jerk-out of a motor, a real component ReI of a stator current is obtained as almost the same value as a torque current, while a reference acceleration Aref is obtained as almost the same value as a motor acceleration by a means of linear regression, and an intercept Y which determines the relation between the ReI and the Aref is supplied. The intercept Y determines the ReI at a definite high speed (ReI: the definite high speed) and correlates the definite speed of the ReI linearly with a compensation frequency fcomp. The compensation frequency fcomp is supplied to be added up with fref used for showing a motor speed. The stator current and the Aref are sampled in the jerk-out on the occasion when the motor is driven at a high speed, because the real component ReI of the stator current is at almost the same value as that of the torque current.

IPC: H04B3/54
Filed: 1988-06-10
Abstract: PURPOSE:To attain 2-frequency transmission between terminal equipments without increasing the number of transmission circuits of the terminal equipment by providing a signal repeater converting a transmission frequency from the terminal equipment into a signal of other frequency. CONSTITUTION:In case of sending a communication signal from a terminal equipment 10 to a terminal equipment 11, for example, a transmission circuit 12 of the terminal equipment 10 sends a signal in 125kHz to a power line 1. A signal repeater 18 uses a transmission circuit 20 so as to convert the signal frequency in 135kHz into a frequency of 165kHz and sends it to the power line. The two frequencies, that is, the signal in 125kHz sent from the terminal equipment 10 and the signal in 165kHz sent from the repeater 18 are received by a 125kHz reception circuit 16 and a 165kHz reception circuit 17 provided in the terminal equipment 11. Since the terminal equipment 11 is active when either signal arrives, the communication is implemented without any hindrance. Moreover, since the 125kHz transmission circuits 12, 13 have only to be employed in each terminal equipment, the number of transmission circuits is reduced.

Title: Power source circuit
Inventor: YOKOYAMA HIDEO
IPC: H02M3/335
Filed: 1982-08-20
Abstract: PURPOSE:To prevent a power source circuit from being damaged due to an overcurrent by varying the drive circuit of a main transistor in response to a load current. CONSTITUTION:A primary current i3 which is proportional to a load current i2 flowed through a load R is detected by a current transformer CT, detected in error by an operational amplifier A2, and the base current of a control transistor Q3 is controlled by the output. Thus, the drive current which flows through the base of a main transistor Q1 is controlled. When a load or an internal shortcircuit is detected by the current transformer CT, the output of the transistor CT increases larger than the reference voltage VR1. Accordingly, the conductivity of the transistor Q3 becomes small by the output of an operational amplifier A1. In this manner, the current flowed to the transistor T3 becomes small. Since the conducting time of the transistor Q1 can be further shortened, it can prevent the overcurrent from flowing through the transistor Q1.
