Provided is a configuration which prevents an engine from being unable to start in the state in which dew condensation occurred in a fuel injection pump and froze. The system includes a server system for generating a script program from a set of queries. The regions of the substrate adjacent to the ends of the channel are preferably treated, such as by ion-exchange, to form secondary waveguide portions, optically coupled to the polymer waveguide, for input and output optical coupling with the waveguide. In a region between the inner circumferential portion and outer circumferential portion of the edge, the edge includes a rib, which is protruded in the second direction, and limits a stroke of the diaphragm in the second direction.
