An electrode for an electrochemical cell is provided. After an image is captured by the digital camera, the digital camera checks certain sets of characteristics of the captured image to check the image quality. A multiplicity of inductors can be provided within a confined space by arranging a multiplicity of inductors in parallel, and by fixing them with resin so as to form an inductor array, thereby making it possible to divide a power supply. The display server enables the user to execute GUI applications on local and remote hosts from the terminal via a display server authorization mechanism. A conductive material is deposited into the first notch to form a first portion of the conductive via within the gap. The angle is in the range of not less than 40\xb0 and not more than 140\xb0.
