Abstract: To provide a ground structure-equipped laminated glass for vehicles, with a countermeasure against static electricity on an electrically driven functional layer. The ground structure-equipped laminated glass for vehicles of the present invention, which achieves the above object, comprises a first glass plate, an interlayer and a second glass plate laminated in this order, wherein the interlayer has an electrically driven functional layer, a power supply member electrically connected to the functional layer, a first circuit having the power supply member and the functional layer connected in series, and a second circuit having the power supply member, a flexible ESD shield and a ground member connected in series; the second circuit has a dielectric at least at one point in the second circuit; and the ground member is grounded.

Abstract: An improved tool holding apparatus includes a collet chuck or a steel ball chuck that clamps a pull bolt, which defines the forward end portion of a tool, by resilient force applied thereto from a coned disc spring. The tool holding apparatus further includes a temporary clamping device which is buried in a sleeve to temporarily clamp the pull bolt. A clamping force applied by the temporary clamping device is set at such a level that an arm can draw the tool from a main spindle by gripping the rear end portion of the tool.
