Title: Testing device for welded portion of rectangular steel pipe
Inventor: MIURA FUMIAKI
IPC: G01N29/04
Filed: 1994-09-28
Abstract: PURPOSE: To enable probing the bead-equipped inner surface of a steel pipe by providing an inner surface probe of a specific angle of refraction in a position which is on the outer surface of the steel pipe and distant from an incidence point by a specific distance in a direction perpendicular to a welding line. CONSTITUTION: In order to enhance distinction between a defect echo and an inner-surface bead echo, the testing distance Y1 between a welding line L and an incidence point P is deviated outward from a 0.5.N skip point by α so that Y1 =0.5.S.N+α (S: skip, N: 1, 3 or 5). α= (1/ 6-5/6)ω (ω: bead width). When N=1, a beam is directly applied to an inner surface bead 4; when N=3, the beam is reflected once by either the outer or inner surface of a rectangular steel pipe 1; when N=5, the beam is reflected twice. When the thickness of the steel pipe 1 is great, N is 3 or 5 to match the thickness. The angle of refraction of an inner surface probe 11 is about 65 deg. to 80 deg. to prevent decrease in the distinction between the bead 4 and a defect 6 and to prevent a surface-wave echo and a defect echo from being mixed.  Thus the defect echo can be easily distinguished from the bead echo.

Title: Crc arithmetic circuit
Inventor: KUDO NORIMASA
IPC: H04L1/00
Filed: 1990-09-04
Abstract: PURPOSE:To suppress the operating speed of a CRC arithmetic section to a degree of a bus transfer speed by providing a selector switching a digit matching position of a fed back local dividened so as to attain recursive CRC calculation for each of l-bit in the case of a data of a same length as bus width (l) and a fraction bit length data. CONSTITUTION:A data stored in an input register 25 is inputted to a combination circuit 27 via a bus 26. On the other hand, a register 28 stores a local dividened and the digit matching by a selector 29 depends definitely on a bit length (l) or (k) of the input data and the degree (m) of a generation polynomial G(x). In the case of a data of a same length as bus width (l) and a fraction bit length data, since the selector 29 selecting the fed back local dividened digit match position is provided, the CRC calculation is recursively implemented for each l-bit even when a fraction bit is caused and the operating speed of the CRC arithmetic section is suppressed to a degree of a transfer speed of the bus 15 and low power consumption is attained.
