An indicator panel for an instrument includes a translucent resin substrate having a first face and a second face opposite to the first face, and a design film on the first face of the substrate. The methods involve coating a photoresist trimming composition over a photoresist pattern, wherein the trimming composition includes a matrix polymer, a thermal acid generator and a solvent, the trimming composition being free of cross-linking agents. The valve member is movable between a closed position and an opened position so as to close or open a fluid passage inside the spout. A helical coil fastener which is inhibited from undesirable migration after installation is also provided. In this manner, node locality may result wherein a thread that is executing within the same node in which a lock has already been obtained will be more likely to subsequently acquire the lock when it is freed in relation to other contending threads executing in other nodes. A temperature sensor senses a temperature of the panel andor an environment surrounding the panel.
