Abstract: An energy storage device has an anode, a cathode and an electrolyte membrane, installed in between the anode and the cathode, wherein at least one of the anode, the cathode and the electrolyte membrane is incorporated with a copolymer and the copolymer is grafted to a functional group with ionic conductive function. Therefore, the energy storage device, which utilizes copolymers and electrolyte membranes, has better efficiency of charge/discharge performance; thus the efficiency thereof increases; the lifetime thereof is prolonged effectively.

Abstract: A method for fabricating a pattern on a semiconductor substrate, comprising the steps of: (a) providing the semiconductor substrate having a photosensitive layer thereon; (b) transmitting the semiconductor substrate to an exposure apparatus including several tubes; (c) providing the supporting assembly to support the tubes, where the supporting assembly includes a first supporting rod having several first parallel recesses, a second supporting rod disposed opposite to the first supporting rod, a bridging member connected to one end of the first supporting rod or one end of the second supporting rod; and a rolling member received by the bridging member; (d) providing a photomask to the exposure apparatus; and (e) transferring the pattern from the photomask to the photosensitive layer.

Abstract: A supporting assembly configured to support a plurality of tubes includes a first supporting rod, a second supporting rod opposite to the first supporting rod, a bridging member, and a rolling member. The first supporting rod includes several first parallel recesses. The bridging member is connected to one end of the first supporting rod or one end of the second supporting rod. The rolling member is received by the bridging member.

Abstract: An external-magnet-type magnetic circuit includes an iron core and at least one composite magnet coaxially mounted around the iron core. The composite magnet has two magnetic poles with field directions thereof substantially perpendicular to each other, wherein one of the magnetic poles has the field direction thereof pointing to the iron core, and a magnetism-guiding plate being deposited on the other magnetic pole of the composite magnet and being separated from the iron core by a magnetic gap. Thereby, the composite magnet provides high magnetic flux density in relatively small volume, without the additional use of any magnetism-guiding yokes, and thus is particularly suitable for small-size amplifiers where it helps to improve acoustic sensitivity and acoustic output performance.
