Abstract: A vibration detection element includes substrates, support members, and an oscillator, and may be used as a biosensor and/or for liquid inspection by analysis of oscillator resonant frequency change. The substrates have a space portion, and the support members protrude from the surfaces of the respective substrates into the space portion. The oscillator is disposed between the support members and is capable of vibrating in the space portion. The support members may each include multiple supports which prevent the oscillator from contacting the substrate surfaces. During manufacturing the oscillator may be transferred from the support member of a glass flow path substrate to a silicon flow path substrate by placement of the silicon substrate support member against the oscillator and subsequent removal of the adhesive from the glass substrate support member.

Abstract: An electromagnetic ultrasonic flaw detection method is provided which ensures highly accurate inspection of an interior surface of a fin-implanted heat transfer tube for detection of corrosion and requires less time for the inspection, no contact medium such as water, and less time and less costs for a pretreatment. The method may include moving an EMAT in a fin-implanted heat transfer tube of an air cooling heat exchanger axially of the tube; causing the EMAT to generate an axially symmetric SH wave by utilizing an electromagnetic force to vibrate a tube body of the fin-implanted heat transfer tube to cause resonance; causing the EMAT to detect a resonant frequency; and if the detected resonant frequency is different from a resonant frequency observed when the tube body has a normal wall thickness, judging that an interior surface of the tube body has a corroded portion.
