Title: Method for measuring depth of crack in structure using surface wave
Inventor: GO KAYO
IPC: G01N29/00
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To ensure high accuracy nondestructive measurement regardless of presence of a filler or an iron rod by sampling an oscillating elastic wave astride a crack and measuring the depth of a crack, based on the amplitude of a signal in front and rear of the crack. SOLUTION: Surface of a structure is oscillated by hitting it with a hammer, or the like, and an oscillation signal is sampled by means of a plurality of acceleration pickup sensors positioned on the opposite sides of a crack. In this regard, a surface wave is employed along with energy (speed or displacement amplitude) as a physical quantity. The wave energy decreases during propagation process and attenuates slightly due to viscosity of the structural material. The wave energy is varied across a crack and the extent of variation increases as the depth of the crack increases. Based on the propagation characteristics, acceleration signal in the data sampled by each sensor is integrated and converted into a speed signal thus correcting the effect of geometric attenuation in the amplitude of surface wave speed, wall thickness or sharing wave component.  Depth of a crack is calculated using a corrected amplitude ratio determined through corrective analysis and a surface wavelength.

Title: Image data compression system
Inventor: FUKUDA MASAHIRO
IPC: G06T9/00
Filed: 1986-09-17
Abstract: PURPOSE:To suppress the increase in the quantity of codes by giving an initial value at every block depending on a gradation change and applying a 1st cluster classification. CONSTITUTION:An initial value generating circuit 3 reads an image data by one block from a buffer memory 2 to obtain a maximum gradation Lmax and a minimum gradation Lmin in the block and obtains a difference LD=Lmax-Lmin from the values. Then the difference LD is compared with threshold levels T1, T2 to decide the gradation level displaying the block into 1-3 depending on the quantity of the value LD and also the initial values LA, PK, QK of the representative gradations are given. Moreover, a representative gradation selection circuit 5 uses the representative gradations to classify the picture element of the block to the closest representative. Since the gradation number displaying each block dividing finely the image is optimized, excess data are omitted and a large compression ratio is obtained.
