A non-volatile memory cell, which uses a storage dielectric as the storage element, has a top dielectric between a gate and the storage dielectric and a bottom dielectric between a semiconductor substrate and the storage dielectric. In the antenna device, a power feeding circuit and a primary radiation element are mounted to a printed circuit board. The optical delay circuit section causes a difference in delay between the two polarized components, and the polarization beam combiner section combines the two polarized components output from the optical delay circuit section. The at least one directional light device being selectively operable to project and target at least one indicating light in response to the at least one command signal from the controller.
