A resist composition contains; a resin having a structural unit represented by the formula and a structural unit represented by the formula ; and an acid generator,wherein Raa1 represents a hydrogen atom and a methyl group; Aaa1 represents an optionally substituted C1 to C6 alkanediyl group etc. A quartz crystal resonator element is a resonator element formed by etching a Z plate which is cut at predetermined angles with respect to the crystal axes of a quartz crystal. Upon receiving subsequent data from the client device, the gateway device can access the generated mapping to identify portions of the subsequent data corresponding to particular interface fields or data elements of the client device using the mapping, and can encode the identified portions of the subsequent data, for instance based on data protection techniques defined by a security policy. The central gore also has a stabilizing area knitted therein.
