摘要:
A substrate processing apparatus includes a holder and a heating device. The holder is configured to hold a central portion of a bottom surface of a substrate to be rotated. The heating device is configured to supply a heated fluid to the bottom surface of the substrate. The heating device includes multiple fins, a heat source, a fluid introduction unit and a fluid discharge unit. The multiple fins are arranged along a circumferential direction of the substrate to be located under the substrate at an outer side than the holder. The heat source is configured to heat the multiple fins. The fluid introduction unit is configured to introduce the fluid to the multiple fins. The fluid discharge unit is configured to discharge the fluid, which is heated while passing through the multiple fins, to the bottom surface of the substrate.

A thermal immersion circulator can comprise a heater including a hollow cylindrical main body having an inlet opening at a first end thereof and an outlet opening in a side wall thereof. The heater can include a flexible circuit board having a plurality of resistive bands controlled by controlling electronics such as TRIACs, which can be water-cooled. A thermal immersion circulator including such a heater can be used in scientific laboratories or sous vide food cooking.

A handheld aerosol-generating device may include an emitter configured to emit light, a sensor configured to receive light, and an aerosol chamber configured to hold an aerosol. The emitter may emit light into the aerosol chamber. The sensor may receive light from the aerosol chamber and measure at least one wavelength of the spectrum of the received light. Direct measurement of parameters, and/or the presence, of the aerosol in the aerosol chamber may be enabled, where the direct measurement of parameters of the aerosol in the aerosol chamber may enable optimal operation of an aerosol-generating system that may be the handheld aerosol-generating device.

Devices, apparatus, systems and methods of using a portable heater that does not use a separate compressor or blower or vacuum. The heater can be attached to a piping system to dry interior walls and/or heat coatings in the piping system. The heater can be attached to a manifold having alternative inlet end and two outlet ends. The manifold ends can have quick connect fittings with similar fittings to be easily mateably attached by rotating fittings with one another. A quick connect/disconnect air pressure regulator with quick connect fitting can be attached to the manifold ends. A quick connect/disconnect plug with similar quick connect fitting can close the manifold ends.

Devices, apparatus, systems and methods of using a portable heating unit that does not use a separate compressor or blower or vacuum. The unit can be attached to an inlet of a piping system or section and be used to dry the interior walls of the piping system or section, and/or heat coatings passing through the piping system or section, etc. The portable heating unit includes a heater attached to an inlet end of a manifold, where the manifold can include alternative inlet end and two outlet ends. The inlet and outlet ends of the manifold can have quick connect fittings that allow similar fittings to be easily mateably attached thereto by rotating the fittings with one another. A quick connect/disconnect air pressure regulator with similar quick connect fitting can be attached to anyone of the inlet and outlet ends of the manifold. A quick connect/disconnect plug or plugs with similar quick connect fitting can close off any of the inlet and outlet ends of the manifold. The portable heating unit can be used with both a separate compressor and blower/filter having vacuum generator. The portable heating unit can also be used with only a compressor. The portable heating unit can also be used with only a vacuum generator.

Control system and apparatus for controlling current input to an electrical resistance element such as a seal wire. The system and apparatus of the present invention is a closed loop feedback modification to conventional systems, and takes advantage of the inherent expansion of the seal wire as it is heated. The feedback mechanism monitors both the actual current passing through the wire, and the length of the sealing wire, and adjusts the current applied to the wire, responsive to those monitored inputs. The usage of the sealing machine is also monitored and the application and amount of current flowing to the wire is varied based on this usage.
摘要:
A system for fluid transport at elevated temperatures having a conduit having a fluid inlet end and a fluid outlet end and at least one heating element disposed within the conduit providing direct heating of a fluid flowing through the conduit. The system is particularly suited for preventing condensable constituents of a high temperature fluid from condensing out of the fluid prior to analysis of the fluid. In addition, operation of the system so as to prevent the condensable constituents from condensing out of the fluid surprisingly does not alter the composition of the fluid.

A stirring hot plate for simultaneously heating and stirring a mixture includes a phase controlled motor that spins magnets which couple to, and thereby spin, a stir bar within the mixture. In addition to spinning the magnets, the motor includes an operational mode in which the motor is rapidly braked thereby quickly spinning down the stir bar. The stirring hot plate also includes a visual indicator to the user that the platform is hot-to-the-touch that is especially effective when the stirring hot plate is not in use.
