An opticalelectrical transducer device has housing, formed of a thermally conductive section and an optically transmissive member. In the event that the action meets one or more conditions for creating a nemesis, a computer system controlling the game instance selects a second player account to be invaded by a nemesis. An inner nub is formed by inwardly pressing an upper surface of the plate against a first pressing roller to reduce the thickness of the plate while drawing the plate around a first upper mandrel ring. The fluorescence changes depending on a substance concentration or a pH-value, and the intensity varying correspondingly in time or phase shift of the fluorescent light is allowed to be measured with at least one optical detector with the known intensity or phase of the fluorescence exciting light. A portion receiving the gel pack is composed of the elastomer member, and a portion connected to the housing is composed of the resin member. The method combines with the machining movements of the tool-carrying ram along one or several axes, one or several rectilinear movements of the part to be machined by parametering and digitising the relative travels and speeds of the part to be machined with respect to the tool-carrying ram.
