Inventor: MOTODA MITSUAKI
IPC: G01N27/72
Filed: 1990-04-06
Abstract: PURPOSE:To measure the amount of insertion of a pipe even if the pipe is filled with water or even if the pipe is being heat-treated by generating an eddy current at the connecting overlapped part of a coupling and the pipe with an oscillating coil, and performing temperature correction of a detecting coil which detects the strength of the eddy current. CONSTITUTION:For control circuit 23, a transmitting device 21 which generates an eddy current, a sensitivity switching circuit 22 and a numerical-value setting analog memory are assembled and electrically connected in sequence. A detecting coil 25 detects the strength of the eddy current which is generated in a material to be measured with an oscillating coil 24 as an electric signal. A sensor part 12 has a thermo device 26 and corrects the temperature of the coil 25. Thus the effect of the temperature is removed. The heat generaged in the coil 25 is processed with a correcting circuit 29. The signal is amplified in an amplifier circuit 28. The electric signals outputted from the circuits 28 and 29 are added, and the output signal is obtained. The output signal is displayed on the digital display meter of a display circuit 30 as a generated voltage.

Title: Speed control device for elevator
Inventor: UCHIUMI EIJI
IPC: B66B5/04
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a speed control device for an elevator to realize high- precise control of the elevation speed of a car. SOLUTION: A noise reducing means 1 reduces the generation of high frequency noise contained in a speed deviation between a car speed detected by a car speed detecting means and a car speed command. A target value follow-up control means 2 computes a car speed correction signal to cause a car speed to follow a car speed command based on the speed deviation by which the generation of high frequency noise is reduced. A speed converting means 3 converts a car speed target value, obtained by adding a car speed correction signal, a characteristic change compensation signal, and a car vibration suppression signal to a car speed command, into an electric motor speed target value. Namely, by using a car speed detecting value and by adding a correction signal for a characteristic change and vibration, follow control of the car speed target value is effected. This constitution controls a car speed to a car speed command with high precision.

IPC: H03H7/30
Filed: 1983-05-24
Abstract: PURPOSE:To reduce the number of parts of a short-circuit switch element and to obtain a low-cost switching circuit by utilizing the character that a signal passes through a delay element having a shorter delay time when a delay element having a longer delay time is short-circuited with the delay element having a shorter delay time.
