Filed: 1994-07-19
Abstract: PURPOSE:To prevent the clogging of small water spraying holes by mud or the like by moving rolling members arranged on the bottom surface in a cylindrical water spray tank while rolling them thereon by supplying water from water discharge ports. CONSTITUTION:Water discharged from water discharge ports 33 collides with a water bearing plate 49 or rollers 41, 42 and 43, so that a rolling member 40 is pushed toward the flowing direction of water, the rollers 41, 42 and 43 roll and rotate in the circumferential direction in a cylindrical water spray tank 5'. Support shafts 44 and 45 on which the rollers roll are connected together at a sector angle so as to meet the diameter of the cylindrical water spray tank 5'. Thus, the rolling member 40 successively rolls in the circumferential direction on a bottom surface 36 in the cylindrical water spray tank. Further, since when the guide roller 48 of an upright shaft abuts against the inner wall of the outer frame 31 of the water spray tank, it rotates to serve as a guide, the rolling member is prevented from being caught by the inner wall of the water spray tank and stopping, so that it smoothly rolls and moves in the water spray tank. The rollers 41, 42 and 43 roll and move on the bottom surface 36 of the water spray tank, so that scale or the like adhering to the bottom surface 36 is broken and small water spraying holes are continuously cleaned.

Title: Method and apparatus for inspecting airtightness leakage of package
Inventor: YABUSHITA NOBUKI
IPC: G01M3/24
Filed: 1988-07-28
Abstract: PURPOSE:To inspect leakage rapidly and certainly by partially compressing a hermetically closed deformable package and detecting the wave motion generated when the compressed gas in the package is leaked. CONSTITUTION:At first, a package is compressed by a compressor 1 and the compression signal from a compression signal generation circuit 2 is generated in the compressor 1. When airtightness leakage is present, an ultrasonic wave is detected by an ultrasonic sensor 3 on the basis of the unstable flow of the gas generated in the package. The output signal from the sensor 3 is processed by a processing circuit 4 to perform amplification and waveform shaping. Thereafter, the AND with the window signal synchronous to the compression signal is taken and a detection signal is outputted to a judge circuit 5. The signal is compared with a definite reference in the circuit 5 and, when said signal falls below a definite reference value, it is judged that there is no leakage and, when exceeds said reference value, leakage is judged to be present.
