A co-processor module for accelerating computational performance includes a Field Programmable Gate Array and a Programmable Logic Device coupled to the FPGA and configured to control start-up configuration of the FPGA. In the transistor, over an oxide film which can release oxygen by being heated, a first oxide semiconductor film which can suppress oxygen release at least from the oxide film is formed. The system receives a new pronunciation of the call waiting information and stores information about the new pronunciation for subsequent retrieval. A second set of second radiating elements may also be disposed lengthwise along the center of the ground plane. An inner radius of the negative-electrode side heat radiation fin is smaller than an outer radius of the cooling air inlet window.
