Title: Inspection of corrosion or defect in heat exchanger tube
Inventor: NAKAMURA RINJIRO
IPC: F28F11/00
Filed: 1988-02-09
Abstract: PURPOSE:To provide a tube with an uniform magnetic field along the whole length of the same to detect external local corrosion or defect sharply and measure the size of the tube correctly by conducting an electric current through an electroconductive body arranged so as to penetrate the center of the hollow part of the tube, which is the objective of inspection, and generate a circumferential magnetic field. CONSTITUTION:An electroconductive body 3 is arranged and fixed concentrically to the hollow part of a heat exchanger tube 1 and detecting device 5 is moved to and stopped at the left end of the hollow part of the tube 1. Thereafter, the power source 15 of the electroconductive body 3 is thrown and a turning and moving device 16 is driven to move the detecting device 5 to an arrow sign direction in a diagram through a turning and moving rod 4 to turn and move the device 5. According to this method, a circumferential magnetic field is generated along the whole length of the tube 1 whereby the local change of the magnetic field may be detected by the detecting device 5 as a local corrosion or a local defect when there exists the local corrosion or the local defect in the magnetic field.

Filed: 1989-02-07
Abstract: PURPOSE:To surely detect the whole body picture of a target object by obtaining the picture of the white level part of the target object whose brightness is higher than that of a background part by binarizing it, and simultaneously, obtaining the picture of the black level part of the target object whose brightness is lower than the background part, and synthesizing the pictures of the target object of both levels. CONSTITUTION:An input picture consisting of picture elements having the brightness of plural levels is sent to a white level binarization circuit 11 and a black level binarization circuit 12. Then, the circuit 11 measures the brightness statistic of the circumference of the target of the input picture, i.e., the average mu and the variance sigmaof the brightness, and sets a threshold capable of detecting the target of the brightness higher than a background, and binarizes the white level part according to this value. Besides, the circuit 12 measures similarly the brightness statistic of the circumference of the target of the input picture, and sets the threshold capable of detecting the target of the brightness lower than the background, and binarizes the black level part according to this threshold. Both the white level of the input picture detected by the circuit 11 and the black level from the circuit 12 are sent to a white.black synthesis circuit 13, and both the level parts are picture-synthesized, and the correct picture of the target object can be obtained.

Title: Sampling rate converting device and signal processor
Inventor: SATO MASARU
IPC: H04N9/808
Filed: 1994-02-24
Abstract: PURPOSE:To obtain a signal processor capable of executing rate conversion processing without resetting a clock at the start of a scanning line independently of the number of samples per scanning line and interconnecting integrated circuits through the number of signal lines smaller than the number of quantizing bits. CONSTITUTION:After converting a carry chrominance signal C into color difference signals U, V by a color demodulating circuit 37, a rate conversion circuit 38 executes down conversion processing for multiplying a sampling rate by 1/8. In this case, the down conversion processing is executed after executing false data inserting and data deleting processing so that the number of pieces of data in each scanning line becomes the integer times of 8. Thereby even when a clock is not reset at the start of a scanning line, the sampling points of respective scanning lines match each other in a state that a sampling frequency becomes finally 1/8 times. In an array circuit 40, 2-bit transmission data are obtd. by rearranging respective bit data of the color difference signals U, V subjected to the down conversion processing to be 8 bits for one sample.
