摘要: A treadmill is provided that has a treadmill drive motor carriage that can pivot relative to a frame of the treadmill such that the incline of the treadmill can be controlled while the carriage can be moved to a position that permits upright storage of the treadmill on the carriage. This arrangement advantageously permits a walk through treadmill design to be used that can be stored uprightly. The treadmill can be equipped with a console and stanchion that can be folded against the deck of the treadmill. One incline arrangement pivots the carriage using an incline drive carried by the carriage that engages a gear grounded to the treadmill frame. Another preferred incline arrangement uses a four bar linkage movable carried by the frame that is driven by a linear actuator to pivot the carriage.

摘要: A semiconductor material which has a high carbon dopant concentration includes gallium, indium, arsenic and nitrogen. The disclosed semiconductor materials have a low sheet resistivity because of the high carbon dopant concentrations obtained. The material can be the base layer of gallium arsenide-based heterojunction bipolar transistors and can be lattice-matched to gallium arsenide emitter and/or collector layers by controlling concentrations of indium and nitrogen in the base layer. The base layer can have a graded band gap that is formed by changing the flow rates during deposition of III and V additive elements employed to reduce band gap relative to different III-V elements that represent the bulk of the layer. The flow rates of the III and V additive elements maintain an essentially constant doping-mobility product value during deposition and can be regulated to obtain pre-selected base-emitter voltages at junctions within a resulting transistor.

摘要: A transducer assembly adapted for the pulse-emission of a signal includes a transducer (10) with a drive-circuit (20) therefor. The drive circuit (20) includes a charge-storage device (21), a wound-coil device (23) and one or more switching-elements (24, 25). The assembly can be used to determine the level of a fluid in an enclosed vessel.
