Examples disclosed herein relate to a to a pitch gradient in a lamp filament, and a method of making. In one implementation, a lamp has a bulb filled with a gas. A filament is disposed within the bulb. The filament has a plurality of coils that include a first coil having a first point. The plurality of coils includes a second coil having a second point, and a third coil having a third point. The pitch gradient is defined by a first pitch between the second point and the first point, and a second pitch between the third point and the second point. The second pitch is greater than the first pitch. The second point is 360 degrees away from the first point. The third point is 360 degrees from the second point. A terminal coil is electrically coupled to at least the first coil, the second coil, and the third coil.

A self-regulating heater may comprise a first substrate including a first silicone layer and a first polyimide layer. A positive temperature coefficient heating element may be formed over the first polyimide layer. A second substrate may be located over the positive temperature coefficient heating element. The second substrate may include a second silicone layer and a second polyimide layer.

A heating element unit for an electric resistance heater comprises: a casing; a heating element within the casing; an electrical supply pin in electrical contact with the heating element; an electrically insulating filler between the heating element and the casing; and an electrically insulating barrier provided between portions of the heating element, the electrical supply pin and/or the casing. The electrically insulating barrier has a greater dielectric strength than the electrically insulating filler, and the dielectric strength of the electrically insulating barrier is greater than about 1500 kV/m (greater than about 40 V/mil).

A device for inductively soldering at least one ferromagnetic contact element to at least one conductor structure on a nonmetallic plate, includes a system for fastening a plate during the soldering operation, at least one soldering tool having at least one induction loop or induction coil suitable for emitting a magnetic field, a system for mutually positioning the soldering tool and the contact element such that the switched-on magnetic field of the soldering tool reliably heats the ferromagnetic contact element and thus the solder joint, a generator that is suitable for generating an alternating voltage with a frequency of up to 1500 kHz and that can be connected to the induction loop or induction coil.

The electrothermal film structure includes a supporting layer, a meshed conductive circuit layer and a transparent optical layer. The meshed conductive circuit layer provided on the supporting layer includes several micron-level conductive circuits distributed in a mesh, and the transparent optical layer is provided on the meshed conductive circuit layer.

A laminated glass according to the present invention is a windshield for an automobile to which an information acquisition device for acquiring information from the outside of a vehicle by emitting and/or receiving light can be installed, the windshield including an outer glass plate that includes a first side and a second side that is opposite to the first side, an inner glass plate that is arranged opposite to the outer glass plate and has substantially the same shape as the outer glass plate, and an intermediate film that is arranged between the outer glass plate and the inner glass plate. The windshield includes an information acquisition region that is to be located opposite to the information acquisition device and through which the light passes.

A substrate support includes a heater body, a heater element, and a heater terminal. The heater body is formed from a ceramic material and has upper and lower surfaces separated by a thickness. The heater element is arranged between the upper and lower surfaces and is embedded within the ceramic material forming the heater body. The heater terminal is arranged between the upper and lower surfaces, is electrically connected to the heater element, and has an electrode surface and a rounded surface. The electrode surface opposes the lower surface to flow an electric current to the heater element. The rounded surface opposes the upper surface and is embedded within the ceramic material to limit stress within the ceramic material during heating of a substrate seated on the upper surface of the heater body. Semiconductor processing systems and methods of making substrate supports for semiconductor processing systems are also described.

Laminated glazings with embedded wire circuits, have many uses. But, due to the higher cost of manufacture, they are not widely used. This invention provides a process to reduce the cost of production for embedded wire laminated glazing. Rather than embedding the wire one interlayer at a time, several circuits are produced on the same sheet, cut out and then inserted into the interlayer of each separate laminate during assembly, reducing the direct labor and capital investment required.

Laminated glass includes: an outer glass plate having a first side and a second side; an inner glass plate that is arranged opposing the outer glass plate and has substantially the same shape as a shape of the outer glass plate; and an intermediate layer arranged between the outer and the inner glass, wherein the intermediate layer has a heat-generating layer including: a first bus bar that extends along an end portion closer to the first side; a second bus bar that extends along an end portion closer to the second side; and a plurality of heating lines arranged so as to connect the first bus bar and the second bus bar to each other, and when a predetermined voltage is applied between the first and second bus bars, an amount of heat generated per unit length of each of the heating lines is 2.0 W/m or less.

A heater for an aerosol generating device includes a substrate and a plane heating element formed on one surface of the substrate, wherein the plane heating element includes an electrically conductive track pattern including a sensor seating region formed of a planar track on which an undersurface of a temperature sensor is configured to be seated.
