    Abstract: A two (or more) piston pump system (10) is provided with both pumps (12) being crank (14) driven. The system does not have a mechanical camshaft, but a software algorithm, which acts like one in controller (20). The algorithm will LEARN and create a unique speed profile, which will mimic the mechanical camshaft. For practical purposes the speed profile of output gear is called Cam profile with software acting as an imaginary camshaft. The algorithm utilizes Crank Angle Estimation, Learn Curve Generation, Smoothing and Advance Timing Calculation.

    Abstract: A fluid infusion pump includes a disposable cassette (12) having an inlet (16), an outlet (24), and a fluid chamber (36) between the inlet and the outlet. There is a fixed wall (180) of the fluid chamber and a movable wall (182) of the fluid chamber. A pump body (26) receives the cassette in a fixed operating relationship such that an actuator (62) in the pump body is activatable for reciprocal advancement and retraction with respect to the cassette and is adapted to confront the movable diaphragm when the cassette is received in the pump body. There is a detachable coupling (44) between the actuator mounted in the pump body and the movable wall so that fluid is expelled from the fluid chamber on advancement of the actuator and positively drawn into the fluid chamber upon retraction of the actuator.

    Abstract: A piston-type compressor includes a crank chamber (15), a drive shaft (16), cylinder bores (33), and a valve plate (14). The drive shaft (16) passes through the crank chamber (15), and the valve plate is fixed to the rear of the cylinder bores (33). The drive shaft (16) includes a valve body (47). The rear end surface (47a) of the valve body (47) and the front surface of the valve plate (14) form a valve mechanism (46). The valve mechanism (46) is located in the pressurizing passage (18, 12a, 44). The valve mechanism (46) adjusts the opening size of the pressurizing passage (18, 12a, 44) in accordance with the axial movement of the drive shaft (16) from a reference position. This maintains an appropriate relationship between the pressure in the cylinder bores (33) and the pressure in the crank chamber (15).

    Abstract: PURPOSE: A compressor of a cryopump is provided to prevent trip of the cryopump, and to supply power stably in power failure by supplying direct current power to the battery until operating the auxiliary power of the compressor. CONSTITUTION: A power supply system of a compressor(10) of a cryopump for decreasing internal temperature of the cryopump during impurity removal process is composed of a power supply unit(20) supplying power to the compressor; auxiliary power(30) supplying power in cutting off electricity of the compressor; a direct current converter(40) installed in the front of the power supply unit; and a battery(50) installed between the front end of the direct current converter and the compressor to supply power to the compressor before operating the auxiliary power. Power is supplied stably from the battery to the compressor before supplying auxiliary power in case of electricity failure of the power supply unit.
