A screw and method for processing metal, metallic alloys, and metal matrix composites in a plastic injection molding machine is disclosed. Each of the at least one slice and the at least one tile are not all aligned with one another. The performance summaries can then be analyzed based on performance characteristics to identify poorly performing SQL statements. The code matching filter increases a value of a detection signal for each sensor value which matches its corresponding bit, decreases the detection signal value for each sensor value which is complementary to its corresponding bit, and neither increases nor decreases the detection signal value in response to a sensor value indicating detection of no bit of the binary code sequence. The CPU controls the comparison circuit and the data register and performs trimming in a self-completion manner, thereby making, trimming on a plurality of LSIs easily in a parallel manner and a total test time reduced. An installation bracket may be provided to facilitate installation of the lighting fixture.
