An ultrasonic transducer system is provided. The ultrasonic transducer system includes: a transducer mounting structure; a transducer, including at least one mounting flange for coupling the transducer to the transducer mounting structure; and a tuned resonator having a desired resonant frequency, the tuned resonator being integrated with at least one of the transducer mounting structure and the at least one mounting flange.

A wedge bonding tool including a body portion including a tip portion is provided. The tip portion includes a working surface configured to contact a wire material during formation of a wedge bond. A plurality of notches are defined by one or more surfaces of the body portion.

This wire clamp apparatus calibration method comprises: a step for driving a driving piezoelectric element by applying a predetermined frequency that causes a pair of arm portions to vibrate in an opening/closing direction; a step for detecting whether or not end portions of the pair of arm portions collide with each other on the basis of an output current outputted from the driving piezoelectric element when the pair of arm portions are vibrating in the opening/closing direction; a step for calculating, on the basis of the detection result, reference voltages in a state where the pair of arm portions are closed; and a step for performing calibration of a drive voltage to be applied to the driving piezoelectric element on the basis of the reference voltages. Accordingly, accuracy improvement and stabilization in an opening/closing operation of the wire clamp apparatus can be achieved.

Bonding processing for a plurality of bonding points of different distances with respect to a reference position (origin) of an object to be bonded without changing a moving distance of bonding means is provided. The bonding means, a bonding stage having a work-holder and a rotary mechanism unit for rotating the work-holder, and a control unit for controlling rotation of the work-holder are provided. The bonding means is movable relative to a placement surface of the work-holder in a reference orientation and has a reference position on its moving direction. The plurality of bonding points include bonding points of different separation distances from the reference position along the moving direction while the object to be bonded is being held to the work-holder in the reference orientation. The control unit corrects differences in the separation distances of the plurality of bonding points by controlling rotation of the work-holder.

A curtain airbag device mounting structure includes: a first pillar forming a part of a front pillar and extends substantially along a vehicle height direction; a second pillar forming another part of the front pillar, the second pillar being disposed on a rear side of a vehicle relative to the first pillar at a predetermined distance from the first pillar and extending substantially along the vehicle height direction; a transparent member bridged between the first pillar and the second pillar; and a curtain airbag device including a curtain airbag stored along a roof side rail and the second pillar, the curtain airbag being configured to inflate and deploy in a curtain-like fashion over a side portion of a cabin of the vehicle in case of a collision of the vehicle.

A discharge examination device for examining discharge of a wire-bonding apparatus that applies a voltage between a torch electrode and a wire to procure the discharge therebetween includes a current detection unit, a timer unit and a discharge determination unit. The current detection unit detects a discharge current flowing through the wire. The timer unit measures discharge detection time after application of the voltage before detection of the discharge current. The discharge determination unit determines whether or not the discharge is abnormal based on the discharge detection time. With this, a discharge examination device, a wire-bonding apparatus, and a discharge examination method that are capable of detecting abnormality of discharge are provided.

An ultrasonic transducer system is provided. The ultrasonic transducer system includes a transducer body, wherein at least a portion of a surface of the transducer body includes a processed area. The processed area has a changed condition at the surface of the transducer body.

A wedge bonding tool including a body portion including a tip portion is provided. The tip portion includes a working surface configured to contact a wire material during formation of a wedge bond. A plurality of notches are defined by one or more surfaces of the body portion.
