Title: Detector for revolution defect
Inventor: YAJIMA TOSHIO
IPC: G01P3/56
Filed: 1980-08-05
Abstract: PURPOSE:To accurately detect the revolution defect of a cam shaft despite the  change in the rotating speed of a main motor by respectively detecting the rotating  speed of the main motor and cam shaft of a press machine, and comparing the ratio  between both with a preset threshold value. CONSTITUTION:A tachometer generator 1 detects the rotating speed of the main motor of a press machine and outputs a detection signal Vm. A tachometer generator 2 detects the rotating speed of its cam shaft and outputs a detection signal Vc. Thence, an analog divider 5 operates Vc/Vm and emits a signal Vk. The value of the signal Vk remains constant in spite of a change in the rotating speed of the main motor and when anormality occurs in the cam shaft and the signal Vc changes, said signal changes accordingly. Hence, by comparing the signal Vk and the threshold value Vk by a comparator 6, the revolution defect of the cam shaft is accurately  detected without degrading the accuracy of detection despite the change in the rotating speed of the main motor.

Abstract: PROBLEM TO BE SOLVED: To optimize the total number of channels in use by detecting azimuth using only monochannel transmit-receive action or in combination with bi- channel transmit-receive action according to the level of input signals. SOLUTION: Each of transmit-receive parts I, II, III executes monochannel transmit-receive action of receiving the reflected waves of beams transmitted from transmit-receive antennas A1, A2, A3 by the same antennas A1, A2, A3. In addition to it, the transmit-receive part II executes bi-channel transmit-receive action of receiving the reflected waves of beams transmitted from the antenna A1 by the antenna A2. In the same way, the transmit-receive part III also executes bi-channel action of receiving the reflected waves of beams from the antenna A2 by the antenna A3. In the case of receive level being larger than the specified threshold, only the monochannel transmit-receive action is used, and in the case of the receive level being the threshold value or less, the monochannel and bi-channel transmit-receive action is used in combination to detect azimuth.
