An improved comfort product that uses an airflow through a heat exchanger and into the comfort product to selectively heat or cool an occupant has a support layer contacting and supporting a channel layer. The channel layer has at least one channel with an opening to accept air. The channel layer contacts and supports an engineered distribution layer that has numerous small holes making it air permeable. The engineered distribution layer contacts and supports an air permeable comfort layer that is of such size and shape to support an occupant of the comfort product. The comfort product also has a heat exchanger assembly for supplying heated or cooled air to the opening in the channel. The heat exchanger assembly includes an air intake having an intake fan, an exhaust outlet and a heat exchanger for selectively heating or cooling air flowing through the heat exchanger resulting in selectively heated or cooled supply air and exhaust air. The intake fan forces air through the heat exchanger where some of the air is selectively heated or cooled to be supplied to the comfort product and some air is used as exhaust air (to remove the unwanted heat if the supplied air is cooled or to warm the exhaust side of the heat exchanger if the supply air is warmed.). The selectively heated or cooled supply air then moves through the channels in the channel layer and the exhaust air exits through the exhaust vent. The selectively heated or cooled supply air then moves through the engineered distribution layer where the numerous small holes diffuse the air and then the selectively heated or cooled air then moves through the comfort layer where the air is further diffused and where the selectively heated or cooled air can selectively heat or cool an occupant of the comfort product.

A process for forming a coating on a surface of a substrate, so that heating of the coating material is selective and sufficient to cause at least partial melting of the coating material and permit bonding to the substrate without excessively heating the substrate so as not to significantly degrade its properties. The process generally entails forming a brazing paste containing powder particles dispersed in a binder. The particles are formed of a composition that is susceptible to microwave radiation. The brazing paste is then applied to the surface of the substrate and subjected to microwave radiation so that the particles couple with the microwave radiation and are sufficiently heated to burn off the binder and then at least partially melt to form an at least partially molten layer on the substrate. The microwave radiation is then interrupted to allow the at least partially molten layer to cool, solidify, and form the coating.

The present invention provides a polyester film particularly useful as a base film for a magnetic recording medium such as cassette-type magnetic tape of a digital recording mode and a production process thereof.

The fine protrusions on the film surface are specified by the ratio of 10-point average roughness Rz to center line average roughness Ra (Rz / Ra) on the surface (less than 20), the difference in concentration of carboxyl groups between the surface layer part and the inside of the film, and the number of fine protrusions.

The antennas are connected to opposite sides of a transistor gate, thus creating a termination resistor for the particular antenna. Multiple outputs from the various antennas are then coupled, thus providing responsiveness to electromagnetic radiation of a very broad spectrum.
