Title:
APERTURE DETECTOR AND APERTURE DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2007/063575
Kind Code:
A1
Abstract:
An aperture detector for detecting an aperture (13) formed in a test object (12)
comprises a jet sleeve (28) that faces one side of the test object (12) and jet out
a pressurized fluid toward the one side of the test object (12), a temperature
sensor (20) that faces the other side of the test object (12) the one side of which
is under the fluid pressure applied by the jet sleeve (28), and a processor (38)
that processes a signal from the temperature sensor (20). The processor (38)
detects the aperture (13) according to the difference between a signal when the
fluid passing through the aperture (13) acts on the temperature sensor (20) and
a signal when the fluid cannot pass through the aperture (13).
