Abstract: method of testing a product for the detection of the presence therein of a defect such as a void or an inclusion, comprises cutting the product and examining the resultant noise for the presence therein of an acoustic component representative of the presence of the inclusion. The method is applied to the processing of metal into slabs, bars, rods, wire strip etc., where the ends must be cropped to remove defective material, specifically to the continuous processing of strip metal where metal strips are joined continuously end-to-end, and where the ends of each strip as rolled may include undesired inclusions such as slag. A leading end piece is cropped by a shear, and the cropping of such pieces is continued until the testing method shows that the material at the place of the cut is free of the undesired inclusions. slag. A leading end piece (24) is cropped by a shear the cropping of such pieces is continued until the testing method shows that the material at the place of the cut is free of the undesired inclusions. Apparatus for carrying out the method comprises an acoustic detector which is disposed as close as possible to the cutter to detect the noise of cutting, a suitable amplifier and means for examining the signal to detect therein an acoustic component representative of a defect in the material.

IPC: F16K31/66
Filed: 1982-01-27
Abstract: PURPOSE:To obtain a small size valve mechanism to open and close the valve in accordance with temperature by a structure wherein a ferrite magnet is used. CONSTITUTION:When the temperature of fluid is low, the attraction between a ferrite magnet 1 and an iron piece 2 is larger than the force of a spring 5, resulting in parting the valve 3 from a valve seat 7 so as to allow fluid to flow between the valve 3 and the valve seat 7.

Filed: 1988-01-21
Abstract: PURPOSE:To use an inexpensive DA converter with a large zero drift and to obtain an analog signal with a small zero drift by providing a circuit cancelling the zero drift of a DA converter itself. CONSTITUTION:A DA converter 4 outputs a sum voltage between an analog voltage EA corresponding to an inputted speed command and a zero drift voltage Ed as a DA conversion output. In this case, the same voltage as the zero drift voltage Ed of the DA converter 4 itself is held in the capacitor C and it acts on the opposite polarity as the output voltage of the DA converter 4, a voltage of (EA+Ed)-Ed=EA is given to a sample-and-hold circuit 1b of the next axis. That is, the voltage signal of the speed command only being the result of cancelling the zero drift of the DA converter 4 is inputted. Since the zero drift of the DA converter 4 itself is cancelled even when it is large, motors 3a...3d follow the speed command with high accuracy and their speeds are changed.
