A microwave treatment device of the present disclosure includes heating chamber (1) for accommodating object (2) to be heated, microwave generator (3), heater (7), power feeder (4), detector (5), and controller (6). Microwave generator (3) generates microwaves. Heater (7) includes a heat source other than the microwaves and heats an inside of heating chamber (1). Power feeder (4) supplies the heating chamber with the microwaves. Detector (5) detects reflected power from power feeder (4). Controller (6) controls heater (7) and microwave generator (3). When heater (7) carries out heating, Controller (6) causes microwave generator (3) to generate the microwaves in heating by heater (7). The microwaves have output power such that the reflected power at a level detectable by detector (5) returns. By present disclosure, by understanding progress of cooking, a heating target can be appropriately cooked.

A multi-heat energy source core sample holder assembly for conducting experiment on a core sample includes a core sample holder, a flexible sleeve, and a multi-heat energy generation source arrangement. The core sample holder includes a cylindrical pressure chamber and a pair of disk-shaped flanges positioned along opposite ends of the cylindrical pressure chamber to accommodate at least one fluid injection port and at least one fluid discharge port. The flexible sleeve is arranged within and along the cylindrical pressure chamber to define one or more section(s) to hold the core sample. The energy generation source includes a wire member to be coiled along an internal wall of the flexible sleeve to be supplied with electric current in at least one of a Direct Current (DC) form to produce an electric resistance heating, or an Alternate Current (AC) form to produce an electromagnetic heating, singularly or in combination.

In certain embodiments, inductive heating is added to a metal working process, such as a welding process, by an induction heating head. The induction heating head may be adapted specifically for this purpose, and may include one or more coils to direct and place the inductive energy, protective structures, and so forth. Productivity of a welding process may be improved by the application of heat from the induction heating head. The heating is in addition to heat from a welding arc, and may facilitate application of welding wire electrode materials into narrow grooves and gaps, as well as make the processes more amenable to the use of certain compositions of welding wire, shielding gasses, flux materials, and so forth. In addition, distortion and stresses are reduced by the application of the induction heating energy in addition to the welding arc source.
