    摘要： Provided is a forced acoustic dipole capable of regulating phases and acoustic pressures of first and second acoustic signals output from first and second pole speakers to freely steer the direction of an acoustic lobe. In addition, a forced acoustic multipole array is constituted by a plurality of forced acoustic dipoles. When the phases and acoustic pressures of the first and second acoustic signals output from the forced acoustic dipoles are regulated to steer an acoustic lobe in a specific direction, sound can be heard from a desired direction only without disturbing others.

    摘要： Provided are a structure and operating method of a semiconductor gas sensor having low power consumption. The semiconductor gas sensor is adapted to adsorb gas to a low-dimensional semiconductor nanomaterial at room temperature, output a change in resistance of the low-dimensional semiconductor nanomaterial, apply power to a heater, desorb the gas adsorbed to the low-dimensional semiconductor nanomaterial, and return the resistance of the low-dimensional semiconductor nanomaterial back to initial resistance. The semiconductor gas sensor senses the gas at room temperature using the low-dimensional semiconductor nanomaterial having a high-sensitivity characteristic at room temperature, and drives the heater only when the adsorbed gas is desorbed. Thereby, it is possible to improve a gas sensing characteristic, reduce power consumption, and provide a rapid response speed.

    摘要： Provided is a small form factor optical/magnetic disk including an integrated metal hub and a disk plate. The integrated metal hub includes a circular upper metal hub and a circular lower metal hub integrally formed with and disposed under the upper metal hub. The circular lower metal hub has a smaller diameter smaller than the upper metal hub. A central hole is formed in central portions of the upper and lower metal hubs and passes through the upper and lower metal hubs. The disk plate has a through-hole that is formed in a central portion and is directly associated with the integrated metal hub, and a recess that is formed around the through-hole and allows the upper metal hub to be mounted therein. Since the central portion of the small form factor optical/magnetic disk is not thick, the small form factor optical/magnetic disk can contribute to an ultra thin small form factor information storage device. Also, since manufacturing processes are simple, price and quality competitiveness can be enhanced.
