摘要： An actuator assembly for use in an electronic device is provided. The actuator assembly includes a support tray formed of a conductive metal and defining an aperture extending through the support tray. A seat surrounds the aperture and supports an actuator. The actuator includes a piezoelectric element adhered to a metal substrate larger than the piezoelectric element. The metal substrate bends when the piezoelectric element contracts and expands in response to changes in the charge of the piezoelectric element. An insulator is disposed between the metal substrate and the support tray which electrically insulates the substrate from the metal substrate.

摘要： Disclosed is a transmitting and receiving method for reducing a time-varying channel distortion in an orthogonal frequency division multiplex (OFDM) system. In the present invention, the transmitter defines M sub-channels in one data group, mathematically analyzes a change of channel for each path causing a time-varying channel distortion in a high-speed mobile environment by approximation, calculates a weight value based on the mathematical analysis and assigns the calculated weight value to transmit data of each sub-channel. Subsequently, the receiver combines the signals of these M sub-channels and demodulates the combined signals. Accordingly, the present invention greatly reduces a distortion caused by the time-varying channel to improve a bit error rate and a channel estimation performance.

摘要： A method of forming an isolation film forms a spacer for connecting the edge of an active region to the isolation film. The spacer is on the upper sidewall of a trench and smoothes the transition or step between the level of the isolation film and the level of the active region. Accordingly, a gate oxide film of a uniform thickness can be formed on the entire active region in a subsequent process, thus preventing degradation of the characteristics of the gate oxide film. The spacer can be formed using a sidewall spacer on the hard mask used for forming the trench. The sidewall spacer protects part of the isolation formed in the trench, and etching after removal of the sidewall spacer can round the protected portion to create the spacer. Furthermore, to dispel stresses and defects in the isolation film, annealing for densification of the isolation film can be performed at a high temperature such as about 1150° C. because the spacer mitigates the effects of shrinking or sagging of the isolation film.

摘要翻译： 形成隔离膜的方法形成用于将有源区域的边缘连接到隔离膜的间隔物。 间隔物位于沟槽的上侧壁上，并平滑了隔离膜的电平与有源区的电平之间的转变或台阶。 因此，可以在随后的工艺中在整个有源区上形成均匀厚度的栅极氧化膜，从而防止栅极氧化膜的特性劣化。 间隔物可以使用用于形成沟槽的硬掩模上的侧壁间隔物形成。 侧壁间隔件保护形成在沟槽中的隔离部分，并且在去除侧壁间隔物之后的蚀刻可围绕被保护部分以形成隔离物。 此外，为了消除隔离膜中的应力和缺陷，隔离膜的致密化退火可以在诸如约1150℃的高温下进行，因为间隔物减轻了隔离膜的收缩或下垂的影响。
