摘要： A method for forming a magnetic core for the magnetic circuit of a linear-motor compressor suitable for use in a refrigerant system. The compressor includes a conical armature which reciprocates in a complementary air-gap under the influence of an electromagnetic circuit and a pair of linear complementary return springs connected to the armature between the compressor piston and outboard bearing. The electromagnetic circuit includes a pair of abutting convoluted loops of spirally wound magnetic strip material with a conical air-gap fabricated in the area of abutment. The magnetic core is formed by forming a pair of stacks of magnetic strips having diverse lengths, bending each stack to form a generally C-shaped core section having a generally semi-circular air-gap space defined by the ends of the strips, fastening the C-shaped stacks in opposed abutment to form a generally cylindrical air-gap, and then machining the air-gap into the desired conical shape.

摘要： A moving-iron, linear-motor compressor suitable for use in a refrigerant system, wherein a conical armature reciprocates in a complementary air-gap under the influence of an electromagnetic circuit and a pair of linear (constant rate) complementary return springs connected to the armature between the compressor piston and an outboard bearing. The armature rod is made of magnetically permeable material. The electromagnetic circuit includes a pair of abutting convoluted loops of spirally wound magnetic strip material with a conical air-gap fabricated in the area of abutment. The motor has a layered construction which cooperates with the conical armature and air-gap such that the motor is self-aligning at the assembly stage.

摘要： A heat-sterilizable ultrasonic surgical scanner includes an ultrasonic transducer and a permanent magnet motor for moving the transducer along an arcuate path. The scanner further includes a housing for the ultrasonic transducer and the motor. The housing includes an acoustically transparent window for transmitting ultrasonic energy from and into the housing. A resilient diaphragm permits expension and contraction of a coupling fluid with which the housing is filled without causing fluid loss from the housing due to leakage. The resilient diaphragm is mounted at a location remote from the acoustically transparent window.
