摘要： In the particular embodiments of the invention described in the specification, a first signal generator produces a signal which changes in cycles having approximately straight line segments between maximum and minimum values at a first rate and a second signal generator produces a signal which changes in cycles having approximately straight line segments at a second rate which is an order of magnitude greater than the first rate. The maximum level of the second signal during any cycle is dependent upon the instantaneous signal level of the first signal and the minimum level of the second signal during any cycle is dependent upon a selected fraction of the instantaneous signal level of the first signal. The second signal is used to control the speed of a motor in a continuously changing random manner.

摘要： A vaporizing apparatus and method for providing a vaporized liquid precursor to a process chamber in a vapor deposition process includes a microdroplet forming device for generating microdroplets from a liquid precursor and a heated housing defining a vaporization zone having a vapor flow path from the microdroplet forming device to the process chamber. The vaporization zone receives the microdroplets and a heated carrier gas. The heated carrier gas has a temperature so as to provide the primary source of heat for vaporizing the microdroplets. The vaporized liquid precursor is then directed to the process chamber from the heated vaporization zone.

摘要： The invention provides an apparatus having a tubular member for receiving an endocardial lead implanted within a patient's body. Disposed generally at a distal end of the tubular member is at least one blade or cutting surface. An adjustment mechanism moves the blade between retracted and extended positions to engage the cutting surface with the endocardial lead to cut the lead. Once severed, the cut portion of the lead remains within an inner channel of the tubular member and the apparatus and cut portion of the lead are removed from within the patient. Alternatively, in some embodiments, the cut portion of the lead is disposed externally to the tubular member, and the cut portion and the apparatus are removed from the patient, either separately or together. Various embodiments include the blade pivotally connected to the distal end of the tubular member and activated by a wire adjustment mechanism. Others include a metallic wire for slicing through the lead. Still others include a pneumatically actuated adjustment mechanism that inflates to move the blade and engage the cutting surface with the lead. Some others include a cutting edges disposed on an internal, movable cutting blade and on an opening in the side wall of the apparatus which cut the lead when the cutting blade is operated.

摘要： A vaporizing apparatus for providing a vaporized liquid precursor to a process chamber in a vapor deposition process includes a microdroplet forming device for generating microdroplets from a liquid precursor and a heated housing defining a vaporization zone having a vapor flow path from the microdroplet forming device to the process chamber. The vaporization zone receives the microdroplets and a heated carrier gas. The heated carrier gas has a temperature so as to provide the primary source of heat for vaporizing the microdroplets. A method of vaporizing liquids for vapor deposition processes includes generating microdroplets and utilizing a heated carrier gas as the primary source of heat for vaporizing the microdroplets. A vapor deposition system carrying out the method includes a heated carrier gas and a heated housing defining a heated vaporization zone. The heated housing receives the heated carrier gas. An atomizer for generating microdroplets from a liquid source dispenses the microdroplets in the heated vaporization zone. The heated carrier gas has a temperature so as to provide the primary source of heat for vaporizing the microdroplets in the vaporization zone. The vaporized liquid precursor is then directed to the process chamber from the heated vaporization zone.
