A system for cleaning clogged orifices of a fluid head includes both apparatus and method by which reverse flow of a cleaning solution is combined with providing the vibrational energy of an ultrasonic frequency generator to the fluid head. A liquid pump and a filter interconnect between the input terminal of a fluid head to be cleaned and the input to the cleaning chamber of the apparatus so that a liquid cleaning solution reverse flushes the clogged fluid head, while the ultrasonic frequency generator is providing vibrational energy to break loose stubborn clogs.

Fluid head cleaning system

A selectively compliant chuck for assembling tiles into larger LCD displays facilitates alignment between a cover plate and a tile. A linear clutch is positioned between the tile chuck and the tile chuck carrier. This allows each chuck to float in the axis perpendicular to the tile's mating surface. The chuck has freedom to move linearly in this axis, and allows for pitch and roll motion as well. This floating connection can be turned on or off at will. Thus, a tile attached to the chuck can be lowered to intimately contact a cover plate and the chuck will compliantly move for high mating tolerances. Thereafter, the clutch can be locked to fix the chuck in it's current position. In this manner, the tile can be raised so that an adhesive can be applied to the cover plate. The tile can then be lowered back over the adhesive with the clutch locked and alignment maintained.

An apparatus for retaining a product, preferably such as a flexible product in a flat and secure position on a generally planar surface. More specifically, the apparatus consists of a self-contained multi-zone vacuum chuck fixture which is adapted to enable the selectively controlled securing and holding of flexible products possessing various sizes and configurations on a flat work surface. The apparatus may be transparent so as to be also utilized as a light table.
