Title: Ultrasonic flaw detecting apparatus of pipe
Inventor: MATSUSHITA MICHIO
IPC: G01N29/04
Filed: 1988-12-28
Abstract: PURPOSE:To make it possible to inspect the corroded state of the surface of the outer wall of a pipe accurately and quickly even if the thickness of the pipe is small by housing two piezoelectric transducers for transmission and reception in a contactor in a flaw detecting apparatus using a water immersion type ultrasonic wave reflection method, bringing the contactor into close contact with the inner wall of the pipe, and performing high speed scanning. CONSTITUTION:The inspection contact part of a contactor 1 is pushed with a spring guide 8 of a housing 7 and brought into close contact with an inner wall surface 10a of a pipe to be inspected 10. Two piezoelectric transducers 2a and 2b for transmission and reception are juxtaposed in the axial direction of the pipe with a sound splitting plate 3 in-between. In this way, resolution is enhanced. When the thickness of the pipe is 0.5mm or more, measurement can be performed sufficiently, and the scanning speed can be increased. The echo wave of the oscillated ultrasonic wave puls from he surface of the inner wall is hardly received because of the splitting plate 3. The echo from the surface of the outer wall is received. The elapsed time is measured with a counter module 13a. Thus the distance between the inner wall and the outer wall of the pipe is accurately obtained, and the state of corrosion can be detected.

Title: Method for turning spherical body arrangement into image, measuring method and device, and manufacture of piano lens and device therefor
Inventor: ASHIZAKI KOJI
IPC: B29D11/00
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To measure a filling state of microbeads in a transmission type screen, in which the microbeads are employed. SOLUTION: Bead-arrangement is picked up by illuminating beads with a reflecting lighting or a transmitting lighting so as to observe a calescent point lighter than the outside of the bead within the bead and to bring the outer peripheral part of the bead darker than the outside of the bead. From these image data, the calescent point within the bead is detected so as to successively smear out a pixel, the brightness of which is higher than t2 among pixels adjacent to one another by employing the detected calescent point as the starting point. After that, the data are binary-coded by a threshold level of t3 . The areal filling percentage of beads is calculated on the basis of the number of white or black pixels of the obtained binary image. Circular or circular arc patterns corresponding to the dark part of the bead outer peripheral part are detected by means of a pattern matching technique from the image data so as to smaer out the inside of the circle or the circular arc and then the image data may well be binary-coded.

Then, the most appropriate position of the pad 3 is calculated by means of a subroutine; the pad 3 is arranged on the basis of its calculated result. When the position is to be decided by this calculation, its horizontal direction is given on the basis of arrangements x1, x2,... of cells including their respective pads 3a-3d, and its vertical direction is decided by Y1, y2,... of the pads 3a-3d inside their cells 2a-2d. By this setup, it is possible to arrange the pads 3a-3d in the most appropriate positions.

Abstract: PROBLEM TO BE SOLVED: To instantaneously obtain an jetting amount of ink from a nozzle by detecting density of ink dot or line pattern formed with the ink jetted from head. SOLUTION: Windows (to obtain an image by scanning m pixels in a width direction of a line pattern) made of n×m of pixels are provided for an image of a line pattern to be measured by capturing it by a line sensor camera to obtain luminance Qnm of each pixel. And, windows of the same size are provided for an image captured on a part having no line pattern to obtain an image reference luminance Inm of each image at that time. At each corresponding pixel, a pixel density Dnm=Log (pixel reference luminance Inm/pixel luminance Qnm) is calculated, the density Dnm is added in the case of n=1 to n, and m=1 to m to obtain density of the entirety in the windows. An ink amount per one time jetting of a nozzle for printing a line pattern is obtained by using a calibration curve from the obtained density.

Title: Device and method for detecting cut of dynamic image data and record medium
Inventor: KANEKO TOSHIMITSU
IPC: H04N19/50
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To design an optimum cut detecting method by calculating a likelihood ratio of whether or not there is a cut from the appearance frequency of a feature quantity obtained from dynamic picture data, and performing likelihood ratio inspection, based on the likelihood ratio and detecting a cut from a dynamic image. SOLUTION: Data of a dynamic image are inputted from a dynamic image data input part 101. A feature quantity extraction part 102 extracts or calculates a specific feature quantity from the dynamic image. An appearance frequency counter 103 counts how many times a specific value of the feature quantity appears. A likelihood ratio calculation part 104 calculates a likelihood ratio of whether or not there is a cut from the appearance frequency data on the feature quantity counted by the appearance frequency counter 103. Then the likelihood inspection is performed by using the likelihood ratio thus obtained to detect the cut from the dynamic picture. Consequently, the optimum cut detecting method can be designed in a sense that, when one of the nondetection rate and excessive detection rate of the cut is fixed, the other can be minimized.
