[Problem] To provide a bonding device capable of adequately controlling a leading end of a capillary when a ball formed at a leading end of a wire is pressed and bonded to an electrode of a semiconductor chip with scrub vibration. [Solution] The bonding device is provided with a vibration driving portion (7), the vibration driving portion (7) including a plurality of piezoelectric elements (10) that are expanded and contracted along an axial direction of a bonding arm (3) respectively with one end thereof fixed to a leading end of the bonding arm (3), a plurality of capillary holding portions (15) that are in contact respectively with a circumferential face of a capillary (20) at a base end side thereof as being fixed correspondingly to the other end of the piezoelectric elements (10), and a pressing-holding portion (21) that sandwiches the capillary (20) as pressing the capillary (20) to the capillary holding portions (15) with at least one end side fixed to the bonding arm (3) and the other end side being in contact with the circumferential face of the capillary (20) at the base end side thereof on a side opposite to the capillary holding portions (15). Here, functional operation of amplitude, phase, frequency, or waveform is performed on drive voltage waveform to the respective piezoelectric elements.


An object of the present invention is to provide a method for controlling microorganisms in food materials, by which bacterial groups that cause deterioration of the quality of food materials such as poultry and pathogenic microorganisms that cause food poisoning can be efficiently controlled. Specifically, the present invention relates to a method for controlling microorganisms in food materials, comprising a step of subjecting a food material immersed in a sterilizing solution to repeated treatment with negative pressure and ordinary pressure and/or a step of subjecting the food material immersed in the sterilizing solution to resonant ultrasonication.
