An internal antenna especially aimed at flat radio devices. The custom toe images allow the wearer of the socks to \u201canimate\u201d the toes of the socks by wiggling each digit, creating a puppet effect. An analog to digital conversion unit converts the DC signal into a second pulse width modulating signal according to at least one of an environmental condition and a load state of an electronic device, wherein the second pulse width modulating signal controls the brightness of the display. Each assembly includes a rigid plate having two bulb seals extending along opposite edges of the plate that are coextruded with the plate. To these ends, the inventive method is used to produce a Si substrate having a p+ layer and an n layer. That is, the present invention is a recording medium having a coating layer comprising a polyvinyl alcohol resin containing an acetoacetic ester group, a zirconium compound and an inorganic powder on the surface of a substrate.
