Provided is a MIMO communication device which can maintain the MIMO communication characteristic at a certain level regardless of the device installation position. The compressor and the electric motor are accommodated in a common gastight housing, provided with a gas inlet and a gas outlet. A luma error quantizer quantizes the luma error information to determine a quantized error value on a per pixel basis. In yet another embodiment the container comprises a tube for receiving food items and having permanent or releaseable seals at the ends thereof. Further, the soldering portion may have a through hole adjacent to the rough face to insert the second terminal. The timing circuit is coupled to the source of precision time signals to receive a precision time signal there from, and is operable to generate clock information based on the precision time signal.
