Cooking device includes heating chamber with door for housing object to be heated, vapor generator for supplying vapor into heating chamber, and water storage tank. Cooking device further includes cooling air passage provided between heating chamber and water storage tank and allowing cooling air to pass therethrough, and air inlet provided to the side of door and introducing cooling air into cooling air passage. This enables cooling, using a smaller and more inexpensive cooling fan. As a result, cooking device is made shorter in overall height.

A defrosting tray includes a metal substrate, a thermal conductive ceramic coating formed on the top surface of the metal substrate, and an inorganic nanocoating formed on a top surface of the thermal conductive ceramic coating. The thermal conductive ceramic coating is configured to enhance a heat transfer capability of the metal substrate. In particular, the first ceramic coating and the first inorganic nanocoating together define a defrosting surface with sub-micron pyramidal arrays.

A heating article includes a substrate having two opposite surfaces, at least one of which is opaque, and a heat-stable coating arranged on the opaque surface. The heat-stable coating includes an at least two-color decoration having continuous tones and being provided in the form of a continuous or discontinuous layer. A method for manufacturing such an article includes applying a decoration composition on the opaque surface of the article to form a moist decoration layer, and then heating the moist decoration layer to form a decoration having the form of one of a continuous or discontinuous layer.

Several embodiments include a cooking instrument. The cooking instrument can select a food cooking recipe and identify relative areas in a cooking chamber to place at least two portions of food. The relative areas would match the food cooking recipe. The cooking instrument can display information associated with an instruction to place the at least two portions of food over the relative areas. The cooking instrument can then determine a heating sequence in accordance with the food cooking recipe and control, based on the heating sequence, a heating system to directionally transfer heat under different heating characteristics respectively to the at least two portions of the food at the identified relative areas in the cooking chamber.

A method of making and using a medical delivery device includes forming a first compartment to contain at least a portion of an activator, where forming the first compartment includes forming a first wall with a first ferrous material such that the first wall disintegrates in response to first electromagnetic radiation received by the first ferrous material. Upon contact, the activator activates one or more molecular nanomachines. The method also includes forming a second compartment adjacent to the first wall of the first compartment to contain the one or more molecular nanomachines. The second compartment includes a second wall that includes a second ferrous material. The second wall is configured to disintegrate and release one or more activated molecular nanomachines into a patient in response to second electromagnetic radiation received by the second ferrous material.

The present invention relates to a heat-cooker having excellent durability wherein a silane compound-based transparent coating layer containing filler is formed on the external surface of a ceramic coating layer of a cooking surface of a heat-cooker. Compared to conventional porcelain enamel based heat-cookers, the cooking utensil of the present invention is lighter, and the transparent coating layer protects the ceramic coating layer to thereby improve durability and provide excellent non-stick characteristics.

A cooking device, system and method are disclosed herein. In one embodiment, the method requires a microwavable cooking sheet to be provided, wherein the microwavable cooking sheet is comprised of a single layer of a primary material that is non-plastic and wherein the primary material has a weight of between 18 pounds per 3000 square feet and 60 pounds per 3000 square feet. The microwavable cooking sheet may be wetted and then wrapped completely around food to be cooked in a microwave. The food is cooked in the microwave with the wet microwavable cooking sheet wrapped around the food, such that a pressure increase of at least 3/16.sup.th of an inch of H.sub.2O is built-up within the microwavable cooking sheet.
