A concealing cup surrounds the frame arms. A cover plate is attached to the concealing cup, covering the distal end thereof, wherein the drop pins and the deflector are positioned within the concealing cup. The cover plate is removable from the concealing cup permitting the drop pins and the deflector to axially slide out of the concealing cup into an operational position.

Abstract: The processing of radiation patternable organometallic coatings is shown to be improved through the appropriate selection of post processing conditions between coating and development of the pattern. In particular, a coated wafer can be subjected to process delays to allow aging of the coating at various process points, in particular following irradiation. Process delays can be combined and interspersed with heating steps. The atmosphere above the coated wafer at various process steps can be adjusted to obtain desired improvements in the development of the pattern. Reactive gases can be beneficial with respect to improvement of coating properties.

Abstract: Precursor solutions for radiation patternable coatings are formed with an organic solvent and monoalkyl tin trialkoxides in which the water content of the solvent is adjusted to be within 10 percent of a selected value. Generally, the water content of the solvent is adjusted through water addition, although water removal can also be used. In some embodiments, the adjusted water content of the solvent can be from about 250 ppm by weight to about 10,000 ppm by weight. With the appropriate selection of ligands, the adjusted precursor solutions can be stable for at least about 42 days, and in some cases at least 8 months.

Abstract: A method for patterning a radiation sensitive material on a substrate involves the development of a material on a substrate based on a latent image in the material with irradiated regions and non-irradiated regions to form a physically patterned material on the substrate, in which the material comprises an organotin radiation sensitive patterning material and an additive. The additive is a photoacid generator, a quencher or a mixture thereof. Patterning improvements can be achieved using a series of a baking and development step followed by a second baking at a higher temperature and a second development step following the second baking step. A precursor solution for forming an organometallic radiation patterning material can comprise an organic solvent, a dissolved organotin composition having C—Sn bonds that can cleave in response to EUV radiation, and a quencher. The additive can comprise an onium cation.

Abstract: A thermal trigger assembly for remote mechanical actuation of another fire protection system component includes an activation component having a base and a movable member.
