A cast carbon steel strip is prepared by continuously casting in a twin roll caster and cooling to transform the strip from austenite to ferrite at a temperature range between 400 C. The hearing-aid device comprises a piezoelectric-type actuator, housing and connector. A distal end of a second wire is also coupled to the voltage source and a proximal end of the second wire is coupled to the instrument. The slider includes a base portion pressing against the contacting portions of the terminals and a pair of arm portions extending laterally from the base portion. Personal information is detected by scanning contents of the data when the data is subject to personal information management. The air layer is formed, with the die being held via vacuum suction by a suction nozzle provided above the suction holding stage, by raising the tape peeling stage and then by moving the tape peeling stage horizontally in a direction away from the die.
