US Patent:

6997673, Feb 14, 2006

Filed:

Dec 11, 2003

Appl. No.:

10/734922

International Classification:

F01D 25/12
F01D 11/08

US Classification:

415 1, 415139, 4151731, 415178, 4152141

Abstract:

A turbine shroud assembly includes forward and aft hangers, an axisymmetric plenum assembly, ceramic shroud segments, ceramic spacers, and forward and aft rope seals. The plenum assembly supplies impingement cooling to the shroud and the hangers. The impingement cooling to the forward and aft hangers is controlled independently to improve blade tip clearance. The rope seals are radially inward from the hangers and reduce cooling flow leakage. The turbine shroud assembly can operate in a higher temperature environment using less cooling flow than the prior art.

International Classification:

G03C 1/00

US Classification:

430270100

Abstract:

A topcoat material for applying on top of a photoresist material is disclosed. The topcoat material comprises a polymer which is sparingly soluble or insoluble in water at a temperature of about 25 C. or below but soluble in water at a temperature of about 60 C. or above. The polymer contains poly vinyl alcohol monomer unit and a poly vinyl acetate or poly vinyl ether monomer unit having the following polymer structure: wherein R is an aliphatic or alicyclic radical; m and n are independently integers, and are the same or different; and p is zero or 1. The topcoat material may be used in lithography processes, wherein the topcoat material is applied on a photoresist layer. The topcoat material is particularly useful in immersion lithography techniques using water as the imaging medium. The topcoat material of the present invention are also useful for immersion lithography employing organic liquid as immersion medium.

Appl. No.:

5/518559

Inventors:

Carl T. Larson - Richmond CA

International Classification:

A44B 910

US Classification:

24156

Abstract:

A device having an elongated member, a head having a passage for receiving one end of the member and means coupling the head with the opposite end of the member with the latter being movable into and out of the head. The head has improved means to releasably lock the end of the member therein, such means including a pair of relatively shiftable members normally in engagement with each other and movable apart to present an access passage therebetween. A number of embodiments of the device are disclosed.
