A component-mounted substrate moved to a specified substrate position by a substrate holding-and-moving device is delivered from a top of the substrate holding-and-moving device to a substrate discharge holder, and then while the substrate discharge holder is not moved, the substrate holding-and-moving device is moved to another substrate position, where a new substrate is received. Carbon may be implanted and annealed in a base-emitter junction region for the thyristor to affect leakage characteristics. The method including: providing a list of terms in an input document which match concepts represented by the semantic network, and a frequency value for each matched term indicating the number of times the term appears in the document; mapping each matched term to a referent node or to a plurality of possible referent nodes in the semantic network, and assigning weights to nodes. Performance is optimized by keeping the evaporator substantially full at all orientations while leaving a void for accumulation of vapor in the condenser. The sealing head is air cooled within the induction sealing unit. Preferably, each end of the packer has at least two backup rings molded therein, and slots in the adjacent backup rings are preferably offset at the ends.
