Abstract: A glass-tube heater includes a glass tube, a cap, and a temperature display unit. The glass tube is provided therein with an off-water protection sensor or a tipping switch, a control circuit board, one of a TRIAC and a relay, and a heating element. The control circuit board includes a control unit (which is an MCU or a comparator). All the components that are disposed in the glass tube are electrically connected to form a control circuit. Devices for temperature control, detection, and heating are all disposed inside the glass tube. The off-water protection sensor is operable to detect if being removed out of water for controlling the heating element to carry out heating or not, thereby ensuring quick termination of heating upon removal out of water. The tipping switch is operable to control the heating element from heating in case of excessive tipping of the heater.

Abstract: An HVACR fan and heater assembly accounts for the cyclonic flow produced by centrifugal blowers by placing a heater vertically and biased towards a side of a fan cabinet in order to increase and balance airflow through the heater, eliminating hot spots and fire risk and improving heater efficiency. A blockoff in the fan cabinet forces airflow within the cabinet to move through the heater. The positioning of the heater may vary depending on the direction of rotation of the centrifugal blower. The fan and heater assembly may further include baffles to direct the airflow from the centrifugal blower.

An object is located in the hollow cylinder. A voltage is supplied between the at least two electrodes.

Abstract: A conductor of a power transmission line has its effective resistance to flow of direct current or low-frequency current (such as, for example, 50 Hz or 60 Hz) varied in a wide range to pass current and/or to generate heat for melting ice. Increasing the initial resistance of a conductor is accomplished by modulating the current at a high frequency (HF), such as about 1 kHz to about 100 kHz. The current through the conductor then becomes a mixture of a DC (or low-frequency current) and a high-frequency current. Because the latter flows in a thin skin-layer region of the conductor of depth dependent on frequency, the conductor's resistance to the HF current is higher than its resistance value for low frequency or DC current. By varying the frequency of current modulation in accordance with the present invention, the conductor's resistance is adjusted to a desired value for ice removal.

Abstract: The present invention relates to an electronic cooker, and a method for a game using the same. According to the method for a game using the electronic cooker, when a cooking start command is input through a keypad, a microprocessor causes games, which have a game time equal to a cooking time among games stored in a memory, to be displayed on a display unit, and allows a user to select one of the games. The microprocessor performs control such that the cooking operation and the game can be simultaneously executed during the cooking time. When the cooking time elapses, the game is ended. Therefore, the method for a game using the electronic cooker has an advantage in that the user can play a game during a waiting time for cooking, thereby improving user's satisfaction in the cooking process.
