A technique for penile enlargement. A piezoelectric electroacoustic transducing device 10 has: a frame 15; a piezoelectric vibrator 11 in which piezoelectric elements 12A, 12B are bonded to a metal plate 13; and a plate- and ring-like support member 14 which supports a peripheral portion of the piezoelectric vibrator 11 on the frame 15. The vacuum pulls the residual limb into firm and total contact with the socket and prevents the loss of fluids in the residual limb. The method further includes determining whether re-executing the corrected business process was successful; and setting a status of the post-processing order related to the business process to indicate completion and setting a status related to correcting the error to indicate completion, if re-executing the failed business process was successful. A method for connecting a head interconnect circuit to a printed circuit supported on an head actuator including aligning an alignment finger on the lead tip with a printed surface of a drive circuit for soldering leads on the lead tip to solder pads or connectors on the drive circuit. An emulator for testing an application using a profile of a target device is also disclosed.
