Aesthetic method of biological structure treatment by magnetic field
ActiveUS20180001106A1Improve effectivenessReduce self-heatingElectrotherapyMagnetotherapy using coils/electromagnetsMuscle contractionAdipose tissue
In methods for treating a patient, a time varying magnetic field is applied to a patient's body and causes a muscle contraction. The time-varying magnetic field may be monophasic, biphasic, polyphasic and / or static. The method may reduce adipose tissue, improve metabolism, blood and / or lymph circulation. The method may use combinations of treatments to enhance the visual appearance of the patient.

Polarization field enhanced tunnel structures
InactiveUS6878975B2Moderate and light levelEnhances a dopant-induced drift fieldDiodeSemiconductor lasersTunnel diodeElectrical conductor
A novel tunnel structure is described that enables tunnel diode behavior to be exhibited even in material systems in which extremely heavy doping is impossible and only moderate or light doping levels may be achieved. In one aspect, the tunnel heterostructure includes a first semiconductor layer, a second semiconductor layer, and an intermediate semiconductor layer that is sandwiched between the first and second semiconductor layers and forms first and second heterointerfaces respectively therewith. The first and second heterointerfaces are characterized by respective polarization charge regions that produce a polarization field across the intermediate semiconductor layer that promotes charge carrier tunneling through the intermediate semiconductor layer. In another aspect, the invention features a semiconductor structure having a p-type region, and the above-described heterostructure disposed as a tunnel contact between the p-type region of the semiconductor structure and an adjacent n-type region.

An induction heating cooker includes an infrared sensor for sensing an infrared intensity from a load pot, a waveguide for guiding infrared radiation from the load pot to the infrared sensor, a first magnetism-proofing unit and a second magnetism-proofing unit for reducing magnetic fluxes leaking from a heating coil. Placement of the waveguide at a position lower than an upper surface of the second magnetism-proofing unit reduces self-heating of the waveguide due to magnetic flux supplied from the heating coil. As a result, a temperature rise of the infrared sensor due to radiation heat from the waveguide can be reduced, and an accuracy of sensing a temperature by the infrared sensor can be improved.

Extruder, specifically an extrusion welding device
InactiveUS20060146642A1Improve degassing effectAvoid inclusionsRotary stirring mixersMixing/kneading with horizontally-mounted toolsHand heldScrew thread
The invention concerns an extruder, specifically a hand-held extrusion welding device. For the purpose of degassing a synthetic material to be extruded that is already partially plasticized in the extruder, the invention proposes a thread-less area between two screw threads of an extruder screw. The compression of the synthetic material to be extruded expels gas from the synthetic material, the expelled gas flows against the feeding direction, and exits from the extruder at a feed opening. The extruder proposed by the invention offers the advantage of a complete, or at least an almost complete, degassing of the plasticized synthetic material.

A device (1) for determining the qualify of a medium, particularly of a lubricant and / or cutting oil, includes a number of sensors (3, 4, 5, 6, 7) that emit electric output signals according to the respective sensor-specific input variables. One sensor is a temperature sensor (7) that emits an output signal, which is essentially only dependent on the temperature (T) of the medium and is essentially independent of, in particular, the quality of the medium. At least one other sensor (3, 4, 5, 6) emits an output signal that is dependent on both the quality of the medium as well as the temperature (T) of the medium. The sensors (3, 4, 5, 6, 7) are placed on a shared substrate (2) that can be immersed in the medium. An associated process also determines the quality of a medium.
