A method for calibrating a wire clamp device includes: preparing a wire clamp device provided with a pair of arm parts having tips for clamping a wire, the arms extending from the tips toward base ends, and a drive part provided with a piezoelectric element for drive, connected to the base ends of the pair of arm parts and opening/closing the tips of the pair of arm parts; a step of detecting, by electrical continuity between the tips, a timing at which the pair of arm parts enters a closed state when the piezoelectric element for drive is driven, and acquiring a reference voltage; and a step of calibrating, on the basis of the reference voltage, an application voltage to be applied to the piezoelectric element for drive. Thus, it is possible to perform accurate and stable wire bonding.

A driving mechanism including a first rod (103a), a second rod (104a), a first planar motor (106) moving on a plane, a center planar motor (105) moving on the plane and a moving portion (101), in which one end of the first rod is rotatably connected to the moving portion by a first rotation fulcrum (125a), the other end of the first rod is rotatably connected to the first planar motor by a second rotation fulcrum (126a), one end of the second rod is rotatably connected by a third rotation fulcrum (128a) provided on the first rod. The other end of the second rod is rotatably connected to the center planar motor by a fourth rotation fulcrum (127a), and the moving portion is moved so as to recede from the center planar motor when the first planar motor is moved near to the center planar motor.

A positioning table, for example for a wire bonder has first and second arms, each of said first and second arms being independently drivable linearly along a first axis, and a stage that is engaged with both the first and second arms. The stage engages with each of the first and second arms via a respective engagement mechanism such that the stage is movable both linearly along the first axis, and rotatable about a rotary axis coincident with a center-point of the stage, the rotary axis being orthogonal to the first axis. Each engagement mechanism is configured to permit a respective distance between the center-point of the stage and an end of each of the first and second arms to vary during movement of an arm along the first axis.

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.
