A heating unit has a first heater which is located in the room and movable to be inserted into a container on the container holder along vertical direction so as to cook food in the container.

Abstract: A resident measurement system for a charge level of a blast furnace includes a chamber, a servo system, a distance measurement unit, and a cooling-cleaning unit. The chamber is combined with a lateral furnace wall of the blast-furnace, covers an opening of the furnace wall, and has a pivoting hole. A pivot of the distance measurement unit is pivotally disposed at the pivoting hole, and the distance measurement unit is driven by the servo system to perform a motion with the pivot as a movement center, so as to measure the charge level. The cooling-cleaning unit is used to supply a high-pressure gas, which flows through the distance measurement unit to perform cooling and cleansing operations.

Abstract: A case for a display device comprises a front half casing and a rear half casing. The front half casing includes a rim portion and a hollow portion. Preferably, at least one first and second connecting elements are respectively provided at the front and rear half casings and are arranged to be screwable with each other. Preferably, a support element is connected between the front and the rear half casings for maintaining the rear half casing apart from the front half casing at a fixed angle after the case is open. Preferably, a receiving casing for locating an airflow-generated device used for heat dissipation is provided to be in detachable connection with a bottom of the rear half casing for providing airflow into the case. Preferably, a waterproof frame is provided and fastened onto an external surface of the rim portion for waterproof protection.
