Title: 薄膜型光路調節装置及びその製造方法
IPC: G02B26/08
Filed: 1997-03-05
Abstract: (57)【要約】
薄膜型光路調節装置及びその製造方法が開示されている。前記装置は、電気的な配線及び連結端子が形成された基板、前記基板の上部に形成された支持層、前記支持層の上部に形成されて第１信号が印加される下部電極、前記下部電極に対応して形成されて第２信号が印加されて電気場を発生させる上部電極及び前記上部電極と前記下部電極との間に形成されて前記電気場によって変形を起こす変形層を含むアクチュエータ、前記基板の一側に形成されて前記上部電極と連結して、第２信号を前記上部電極に印加する共通電極線、そして前記上部電極の上部に形成されて光束を反射する反射手段を含む。前記装置は基板上部の連結端子が形成された部分を避けてアクチュエータを形成した後、連結部材を通じて連結端子から下部電極に第１信号を印加するために、基板に形成された電気的な配線及び連結端子が損傷を受けることを最小化できる。また、アクチュエータの一側に厚く共通電極を形成することによって、共通電極内部の抵抗による電圧降下を最小化して上部電極に変形層変形を起こすのに必要な充分の電流を印加できる。そして、第２犠牲層を塗布して２個のポストを通じて反射部材を支持することによって、反射部材の水平度を向上させることができる。

IPC: H01L25/18
Filed: 1985-07-10
Abstract: A power switch device comprises an asymmetrically blocking thyristor (ASCR), with which a diode is connected in series. The ASCR as well as the diode require only about one half the central zone thickness as compared with a symmetrically blocking thyristor laid out for the same blocking voltage in reverse direction (URRM). For the series connection of the ASCR and diode, this results in a much lower blocking delay charge (Qrr).

Title: Echo supressor for 4-wire telephone system, far-end signal treated with weighted filter
Inventor: KIRLA OLLI
IPC: H04R3/02
Filed: 1997-06-18
Abstract: The invention relates to an acoustic echo suppressor and a non-linear processor for an echo canceller in a 4-wire data transmission network. An echo canceller is typically controlled by comparing the power levels of the near-end and far-end signals. The transfer function of an acoustic echo path is usually very non-uniform. According to the invention, the spectrum of the far-end signal is treated, before the signal power level is calculated, with a weighted filter, which models the effect of the transfer function of acoustic echo. As a result, the double talk dynamics is improved, since high-energy vowels of far-end speech, which normally cause low-energy vowels of near-end speech to be clipped in an echo suppresseor, will be attenuated.

Title: Control of power pulses to motor of door operator to ensure constant acceleration and deceleration of motor
Inventor: FITZGIBBON JAMES J
IPC: E05F15/00
Filed: 1999-09-27
Abstract: A door operator electric motor drives the door between open and closed positions using a transmission. A motor control circuit receives a series of pulses and responsive to the pulses starts the motor and drives the motor in one or the other direction.  A controller controls the length of the pulses in the pulse signal in accordance with a predetermined set of values wherein accordingly the speed of the motor is linearly varied from zero to a maximum speed and from the maximum speed to zero.  This linear acceleration and deceleration facilitates a slow and smooth start and stop for movement of the door reducing impulse forces if an obstruction is encountered near the fully open or fully closed positions.
