A bicycle stem for coupling a steer tube to bicycle handlebars has an integrated headlamp assembly which provides an effective, ovular beam spread to optimize use of available energy. The chemically amplified resist composition comprises at least an organic material containing a substituent or substituents capable of being released in the presence of an acid and compounds capable of generating an acid upon exposure to radiation, composed of at least one onium salt and at least one of sulfone compounds and sulfonate compounds. The door covers the opening of the main body. A speckle pattern is formed on the object by the illumination. In one embodiment, speed is improved by utilizing a parallel loaded buffer register which receives parallel data from the high speed shift register and holds that data during the write operation, allowing the shift register to receive serial loaded data during the write operation for use in a subsequent write operation.
