Abstract: Disclosed herein is a refrigerator including a device to restrain the freezing of liquid-phase beverages, thereby stably maintaining the supercooled state of the liquid-phase beverages. The refrigerator includes a main body, a supercooling chamber disposed in the main body such that cool air is supplied to the supercooling chamber, a microwave generator to oscillate microwaves to the supercooling chamber, and a control unit to control the magnitude of the microwaves oscillated from the microwave generator. The present invention has the effect of restraining the freezing of the liquid-phase beverages, thereby stably maintaining the supercooled state of the liquid-phase beverages, and therefore, increasing the supercooled degree of the liquid-phase beverages.

Abstract: A refrigerator and a method to control the same are provided. The refrigerator includes a body having a supercooling compartment, a cooling unit to provide cool air to the supercooling compartment, an electromagnetic radiation sensor to detect electromagnetic radiation emitted when a food placed in the supercooling compartment begins to freeze, an energy supply to apply energy to the food placed in the supercooling compartment to prevent freezing of the food, and a controller to receive a detection signal from the electromagnetic radiation and then to activate the energy supply. Electromagnetic radiation emitted from each beverage in a supercooled state when the beverage begins to freeze is detected and energy is applied to the beverage according to the detection.

Abstract: An evaporator which enables respective side surfaces of an inner liner defining a storage compartment to be uniformly cooled to provide uniform distribution of temperature in the storage compartment. A refrigerator includes the evaporator positioned on an outer surface of the inner liner to absorb heat from the inner liner. The evaporator includes at least two side surface cooling portions respectively positioned on at least first and second side surfaces of the inner liner. The side surface cooling portion positioned at a downstream side to allow refrigerant of lower cooling capability to flow therethrough is longer than the side surface cooling portion positioned at an upstream side to allow refrigerant of higher cooling capability to flow therethrough. The refrigerant cools the inner liner while flowing through the side surface cooling portion positioned at the downstream side for a longer period, enabling a uniform distribution of temperature in the storage compartment.

Abstract: A plasma enhanced chemical vapor deposition apparatus includes a process chamber, and at least one gas injection pipe extending within the process chamber. Each gas injection pipe has an injection region from which source gases are injected through the sidewall of the pipe into the process chamber. To this end, a plurality of slots are located in the injection region. The slots minimize the likelihood that the source gas will be converted to plasma within the gas injection pipe. Accordingly, particle contamination can be minimized.

Abstract: A probe card has probe sections with silicon probes formed on an insulated circuit board that are connected by an adhesive on the supporting structures. The supporting structures are supported by fixing structures with each of the fixing structures being fixed on the circuit board. The probe card has the probe section's wiring and the circuit board's wiring being electrically connected by a metallic wiring and the sub printed circuit and the pogo pin electrically connected by an anisotropic conducting film with the sub printed circuit board and the pogo pin. A metallic layer is formed by the plating of the probe in the probe section. This reduces the manufacturing costs by enabling the damaged probes during manufacturing to be discarded and the others being used continually.
