摘要:
An apparatus (5) is disclosed for internally holding an at least partially hollow substrate (35) having at least one open end. The apparatus (5) includes a member (10) defining a fluid passageway (15), a normally inflated porous material (25) mounted on the member (10) in communication (20) with the fluid passageway (15) of the member, and means, in communication with the member, for deflating the porous material (25), the deflating means being de-energized in response to the porous material (25) being disposed into the opening in the substrate (35) for enabling the porous material (25) to return to being normally inflated to hold the substrate.
摘要:
A chuck assembly (2) which may be inserted into and engage the inner surface of a hollow substrate has a housing (6) having a first open end (8) and a passageway (12) in communication with the first open end, a partially hollow elastic boot (4) having an entry hole which engages the housing and an inner surface which is in communication with the passageway, and a movable, boot stretching member (32) disposed in the passageway and adapted to engage the inner surface of the boot. Movement of the member in a direction to stretch the boot decreases the cross-sectional dimension of the boot, thereby permitting insertion of the boot into the substrate, and movement of the member in the opposite direction increases the cross-sectional dimension of the boot, thereby permitting engagement of the boot against the inner surface of the substrate.

摘要:
There is disclosed a dip coating apparatus including: (a) a single coating vessel (4) capable of containing a batch of substrates (12) vertically positioned in the vessel (4), wherein there is absent vessel walls defining a separate compartment for each of the substrates (12); (b) a coating solution disposed in the vessel (4), wherein the solution is comprised of photosensitive materials and including a solvent that gives off a solvent vapor; and (c) a solvent vapor uniformity control apparatus (22) which minimizes any difference in solvent vapor concentration encountered by the batch of the substrates (12) in the air adjacent the solution surface, thereby improving coating uniformity of the substrates (12).
