    摘要: A low noise gear set for use generally and preferably with a power plant having an engine driving a pump connected to a low pressure fluid source, generating high pressure fluid at an output. The idle gear meshes with the drive gear along two points of the profile of the corresponding gears. The first point being the root of one gear tooth meshing with the tip of the opposite gear tooth creating an initial first contact point and a subsequent second point along the profile when the teeth are disengaging at the first point and engaging at the second point, forming a sealed area, allowing the fluid to hydrostatically escape between the points.

    摘要: A variable capacity pump/motor has a meshing internal and external gear set disposed between an upper mandrel and a lower mandrel, each including a flange extending towards the gears to divide a pump/motor chamber into suction and discharge chambers. The outer gear is fixed and the internal gear is axially moveable with respect thereto. The inner gear and the upper mandrel move in response to changing pressures in the casing, allowing the motor to vary displacement and the pump to vary its output based on supplied fluid pressure or based on the speed of the prime mover. An external configuration includes a pair of meshing gears mounted on separate shafts in a casing. One gear is fixed and the other is axially moveable with respect thereto and moves in response to changing pressures in the casing. Each of the gears is sealed by a seal/bushing on a free end thereof.

    摘要: A system for a heat pump that allows the heat pump to work efficiently in extreme cold weathers. The system includes an evaporator influid communication with an expansion valve, the expansion valve can receive a liquid refrigerant from a condenser of the heat pump. The evaporator contains a pool of liquid refrigerant and an electric resistance heating source dipped in the pool of liquid refrigerant. The electric resistance heating source can heat the liquid refrigerant of the pool to generate vapors and thus maintaining a desired pressure within the heat pump.

    摘要: Laser singulation of electronic devices from semiconductor substrates including wafers is performed using up to 3 lasers from 2 wavelength ranges. Using up to 3 lasers from 2 wavelength ranges permits laser singulation of wafers held by die attach film while avoiding problems caused by single-wavelength dicing. In particular, using up to 3 lasers from 2 wavelength ranges permits efficient dicing of semiconductor wafers while avoiding debris and thermal problems associated with laser processing die attach tape.
