摘要:
The present invention utilizes a dynamically controlled frequency system for the process of induction heating semi-solid material. Semi-solid precursor material is machined into billets of a desired size. These billets are subjected to one or more heating processes utilizing an induction heating process that is dynamically controlled by adjusting the frequency of an induction coil current to achieve a desired temperature in a semi-solid material billet.

A method of heating a refractory oxide material comprising applying a high frequency electric field to heat the refractory oxide material and applying a magnetic field to heat the refractory oxide material. The high frequency electric field substantially heating the refractory oxide material to a temperature range at which the refractory oxide material undergoes a transition in electrical resistivity from an insulator to a conductor. The magnetic field inductively heats the refractory oxide material during and/or after the transition.

The present invention relates to an adhesive coating device for sheet-binding provided with a roller 14, part of which is immersed in adhesive 10 stored in an adhesive reservoir 12, for applying hot-melted adhesive 10 in the above-mentioned adhesive reservoir 12 along the arranged one-side edge of a bundle of sheets 54 while rotating. The device includes an electromagnetic induction heating coil 20 disposed in the vicinity of the above-mentioned roller 14, and a current supply device 5 for supplying a high-frequency current to the above-mentioned electromagnetic induction heating coil 20. The above-mentioned roller 14 is formed of a heating member for generating heat using the Joule heat owing to an eddy current caused by a high-frequency magnetic flux generated by the above-mentioned electromagnetic induction heating coil 20, and the above-mentioned roller 14 is heated by supplying a current from the above-mentioned current supply device 51 to the above-mentioned electromagnetic induction heating coil 20 so that the adhesive 10 stored in the above-mentioned adhesive reservoir 12 is melted.
摘要:
Device for induction heating of ring-shaped objects, including a magnetizable core with one or several coils, which core has a moveable part that is displaceable, for insertion through the ring-shaped object that is to be heated. The object that is to be heated rests on rails or bars on which the object can slide electrically and thermally insulated. The device is inclined laterally so that the objects that are to be heated can slide in to and/or out from the heating position.

A heating apparatus, for heating a material P to be heated by heat from a heat generation member 1 which has a predetermined curie temperature characteristic and generates heat by magnetic flux produced by a magnetic flux generation means 3, includes a discrimination means for discriminating whether or not the curie temperature characteristic of the heat generation member 1 is a predetermined characteristic and a control means for terminating supply of electric power to the magnetic flux generation means when the discrimination means determines that the curie temperature characteristic is not the predetermined characteristic.
摘要:
A method for bonding thermoplastic substrates is provided. A thin, porous, resistive heater is provided between layers of thermoplastic substrates to be bonded in the absence of an adhesive. The fabric heater is in intimate contact with the substrates at the joint by application of pressure. When the heater is energized, the thermoplastic material at the joint is melted or softened, and becomes uniformly distributed in the weld. After cooling, the fabric heater remains within the weld area and provides increased reinforcement to the weld bond.

A method is provided for coating at least a portion of at least one device that includes arranging on a surface of a substrate a solution, directing a beam at the substrate, and arranging the at least one device in an ejection cone formed by a vaporization of the solution. The beam heats the substrate. The solution may be vaporized by a heat transfer from the substrate to the solution. The ejection cone may include a vaporized solution or an atomized solution. The atomized solution may be formed by an explosive vaporization of the solution. The solvent may have a boiling point less than a thermal damage temperature of the bioactive agent. The method may further include arranging on the solution another solution and ejecting by the vaporization of the solution at least a portion of the other solution into the ejection cone. A system for coating at least one device is provided that includes a target assembly adapted to hold a substrate, a beam source directed at the surface of the substrate and adapted to emit a beam, and an arrangement adapted to hold the at least one device in an ejection cone. A solution may be arranged on a surface of the substrate. A medical appliance is provided that has a coating applied by the method.

The invention relates to a laminate, which is characterized in that it comprises at least one layer including a resistance element (1), and at least one layer formed of a fibre reinforced thermoplastic mat (2). The resistance element (1) and the thermoplastic layer (2) are laminated under pressure, preferably by vaccuum moulding, and the thermoplastic is melted under heat and then cooled so that the resistance element is completely or partly enclosed by thermoplastic and is consolidated as a laminate. Further, a method is provided for manufacturing of a fibre reinforced laminated resistance element. In the method, at least one resistance element (1) is arranged together with at least one layer of a mat of reinforcement fibres (25) and thermoplastic fibres (26) in a mould, and the resistance elemetn (1) is moulded together with the fibre reinforced thermoplastic layer (2) under heat so that the thermoplastic fibres (26) melt and fill the fibre reinforcement (25), and under pressure, preferably by vaccuum moulding (28), so that they together form the fibre reinforced laminated resistance element.

A production method of a pattern-indented sheet comprising the steps of pressing a continuously running sheet-shaped medium with a indented roller and a nip roller which are rotating so as to transfer and form indentation of the indented roller surface onto a surface of the sheet-shaped medium and locally heating an upstream portion of a pressing spot of the indented roller.
摘要:
An induction heater is used to heat composite reinforced pipe (CRP) prior to a bending operation. By heating the composite reinforcement to approximately 90° F.-110° F., the incidence of circumferential stress cracks in the resin is significantly reduced. Resin cracking is also reduced by incorporating longitudinal fibers in the composite reinforcement during manufacture of CRP.
