Title: Position measuring system using correspondence relation between images
Inventor: NISHITANI TAKUJI
IPC: G06T7/00
Filed: 1986-04-23
Abstract: PURPOSE:To accurately correlate a pair of images between points by comparing the vicinity of a picture element in which the change of brightness in a pair of images is large, and obtaining the dislocating quantity of a feature point between images. CONSTITUTION:Into an image memory part 13, two images photographed simultaneously from a different position are stored. A pretreatment part 13 executes the smoothing to remove a noise included in the image and the processing to obtain the changing degree (derivative value) of the brightness. A corresponding point determining part 14 obtains the corresponding point of two (right and left) images by using the feature quantity (smoothed brightness value or the derivative value) sent from the pretreatment part 13. The result is sent to a three-dimensional distance counting part 15 and the three-dimensional distance corresponding to respective points on the image is counted. Thus, since the searching scope of the corresponding point can be limited, not only the accuracy can be improved but also an arithmetic quantity can be decreased.

Abstract: PURPOSE:To distinguish the slight and subtle difference of sound in a large background noise for various kinds of machines by comparing an image during operation with an image in normal operation as a reference image. CONSTITUTION:A machine noise that a device to be monitored generates is stored previously in a memory 5 as a signal of time series variation (image) of frequency and sound pressure.

Title: Production of wear resistant steel material excellent in breakage resistance
IPC: C21D9/00
Filed: 1992-03-19
Abstract: PURPOSE:To produce wear resistant steel parts excellent in breakage resistance by subjecting wear resistant machine parts to hardening and tempering and then applying induction hardening to a specific part alone. CONSTITUTION:A material of wear resistant steel, such as Cr-Mo steel, is subjected to ordinary hardening treatment to undergo the improvement of strength, and then the material is temporarily softened by means of tempering at 200-700 deg.C.

Even if microcracking occurs in the deformed layer occurring in the part to be used of this steel material, the propagation of cracks can be inhibited by the presence of the compressive stress and the steel material remarkably improved in breakage resistance can be obtained.
