Briefly, in accordance with one or more embodiments, an image-processing system is capable of receiving an image containing text, applying optical character recognition to the image, and then audibly reproducing the text via text-to-speech synthesis. In one embodiment of the invention, a radial impulse engine includes first and second movable V-members operably disposed between first and second end wall portions. A control member is positioned within the retention tube with a plug attached to the distal end. 06 or less, where, the formula is expressed by,. The edges of the cathode wiring protrude beyond the edges of both the anode wiring and the semiconductor chip in all locations and the dimension of the protrusion is at least one half of the distance from the edge of the cathode wiring to the metal substrate.
