A display device and terminal equipment including the display device are described. Hydrogen, oxygen, and steam are pumped by separate conduits to the burner, which burns at least part of the hydrogen and forces the combustion products out into the earth formation. In one aspect, a method performed by an application executing on a computer system includes receiving a set of images taken during a trip, a corresponding set of acquisition times, and a track path of the trip. 1A and 1B are views of a circuit structure for controlling the writing. The active module includes a pair of cross-coupled transistors that are configured to provide a negative conductance that cancels out a positive conductance associated with the tank module. A plunger is placed on the diaphragm to create a seal with the opposite surface of the diaphragm from the sealing surface.
