The present invention provides an improved metal separator for a fuel cell and a method for preparing same. When a job is submitted from, among terminal devices of the multiple users, a terminal device of one user, notification portion displays a first message associated with the job on another terminal device of another user. The features of the audio signals are detected by the computer as commands for controlling the progress of the slide presentation by simulating keystrokes, mouse actions, or their combinations for the control commands of the presentation software. In response to the request, an identification of the mobile station is placed in a queue of the first network for access to a communication channel. For a desired illumination intensity of a pixel, a series of pulse-width-modulation bit values for the pixel is determined based at least in part upon a parameter that characterizes the asymmetrical transition behavior of the pixel between states. A torque sensor is mounted at the pivot point of the torque arm to measure the torque produced by the golf club as it is supported by the torque arm.
