摘要： A transducer includes a core of low reluctance magnetic material formed with a narrow gap. There are first and second coils of conductive material wound on the core adjacent to and on opposite sides of the gap. A permanent magnet in and substantially filling the gap is in noncontacting relationship with the core and supported to allow relative movement between the permanent magnet and the core. The core may be generally U-shaped, C-shaped or 8-shaped with the path of relative movement between the permanent magnet and the core usually generally perpendicular to the plane of the core. No portion of the core is in the plane of permanent magnet movement. The permanent magnet preferably comprises first and second contiguous permanent magnet elements having adjacent unlike poles along a boundary substantially midway between opposed surfaces of the core along the direction of relative motion.

摘要： An induction cooking utensil is constructed such that it cooks food within its chamber while maintaining a relatively cool outer surface (e.g., preferably an outer surface that is cool enough to pick up with one's bare hands). The cooking utensil includes an inner wall that is made at least in part of an electrically conductive material and an outer wall that is made at least in part of the electrically non-conductive material. A reflective layer, a vacuum-sealed thermal insulator and/or a gas more resistant to conducting heat than air is disposed between the inner and outer walls to resist the transfer of heat from the inner wall to the outer wall.

The bottom portion is made at least in part of a non-conductive material (e.g., so as to not interfere substantially with the magnetic field produced by the induction cooktop) and the sidewall portion is made at least in part of a metallic material.

摘要： A waveguide system for radiating sound waves. The system includes a low loss waveguide for transmitting sound waves, having walls are tapered so that said cross-sectional area of the exit end is less than the cross-sectional area of the inlet end. In a second aspect of the invention, a waveguide for radiating sound waves, has segments of length approximately equal to A  ( y ) = A inlet  [ 1 - 2  Y B + ( y B ) 2 ] where l is the effective length of said waveguide and n is a positive integer. The product of a first set of alternating segments is greater than the product of a second set of alternating segments, in one embodiment, by a factor of three. In a third aspect of the invention, the first two aspects are combined.

摘要： An electromagnetic transducer includes a first member and a second member which are relatively slidable along a path having spaced endpoints and which are electromagnetically coupled. The second member has at least one winding which produces a magnetic field which penetrates the second member. The second member has a plurality of contiguous permanent magnets of alternate polarity along the path which establish a periodic magnetic field which reacts with the magnet field created by the first member so as to produce force along the path. The plurality of contiguous permanent magnets are disposed along the path such that transition lines dividing adjacent ones of the magnets are formed at a non-perpendicular angle to the path to allow gradual transition between flux directions.
