摘要: Both the reaction of hydride-forming compositions with hydrogen to form hydrides, and the decomposition of such hydrides to release hydrogen may be promoted electrochemically. These reactions may be conducted reversibly, and if performed in a suitable cell, the cell will serve as a hydrogen storage and release device.

摘要: Provided is a configuration of a driver integrated circuit that can output a voltage exceeding the withstand voltage of a process, and that satisfies required apparatus performance (high speed and high voltage). A differential input circuit, a level shift circuit, and an output circuit are manufactured by the same process and divided and disposed on three or more chips with different substrate potentials (sub-potentials). By setting different applied voltages to the substrates of the chips, an output voltage greater than the process withstand voltage can be provided (see FIG. 2).
