A double arm substrate transport unit for transporting a work piece, such as a semiconductor wafer, includes a robotic arm formed of a first forearm supported by the tip part of a base arm so as to be freely rotatable. The cream composition contains milk fat, a sugar, and water. The computer system identifies any informational messages associated with each of the addressees, and displays to the user the identified informational messages. The conductive crosslinked body is suitable as an electrode or a wire for a transducer, a wire for a flexible wiring board, and an electromagnetic wave shield. Further provided is a curable powder coating composition including a polymer having a glass transition temperature of at least 30\xb0 C. Following formation of the floating gate an insulating layer is formed on the floating gate and a control gate is formed on the insulating layer.
