In a preferred embodiment, the invention dynamically generates content and presentation to a user by modifying conventional content, e. The trench includes a drink opening on a floor of the trench and the sliding member is configured to cover and uncover the drink opening. At least a part of an outer diameter side of the weight-adding cylinder is embedded in an cylindrical embedded recess that is formed in an inner wall of the shaft body, wherein a grip-side cylindrical end surface of the weight-adding cylinder and a grip-side cylindrical end surface of the cylindrical embedded recess are in contact with each other. The second support member is coupled to the first support member for configuring an intermediate support member therebetween. The thin film transistor comprises: a substrate and a gate, a first gate insulating layer and an active layer which are disposed in order on the substrate, the first gate insulating layer covers the gate, the active layer covers the first gate insulating layer, and a material for the first gate insulating layer comprises aluminum oxide. The frequency sensing and control mechanism automatically detects voltage types associated with output voltages from the ballast and the AC mains in a single-ended or a double-ended lamp fixture and makes proper management so that the universal lamp works for either case and in either fixture without operational uncertainty.
