CONSTITUTION: Each opened cylindrical interference hole(3a1 ....3an ,3b1 ...3bn ,3c1 ....3cn ) is formed in a first, second and third receiving parts(3a,3b,3c) and each net-shaped rib(3a",3b",3c") is formed between the interference holes(3a1 ....3an ,3b1 ...3bn ,3c1 ....3cn ). The interference holes(3a1'...3an') formed in the first receiving part(3a) assume the inverted reverse sharp of "T", the interference holes(3b1'...3bn') formed in the second receiving part(3b) assume the reverse sharp of "L" and the interference holes(3c1'...3cn') formed in the third receiving part(3c) assume the sharp of "U". The ribs(3a",3b",3c") fill up a space formed by an upper end part(3) of a cover(1) and a side wall(2) and prevent a tool inserted through the crack of a door from approaching an actuator. A sound wave generated by the actuator is decreased due to the adjacent interference holes(3a1 ....3an ,3b1 ...3bn ,3c1 ....3cn ).

Abstract: PURPOSE: A method of forming an isolation film is to remove an exposed oxide film or to form the oxide film on a sidewall of a trench, thereby obtaining a high integration of a semiconductor device. CONSTITUTION: A pad oxide film is formed on a semiconductor substrate(11) to release the stress of a nitride film. The nitride film is used as a barrier film. By etching the nitride film, the pad oxide film and the semiconductor substrate, a trench(13) is obtained. To compensate damage during etching, a sacrificial layer is formed with thickness of 130 angstrom to 170 angstrom. This resultant structure is immersed in HF(hydrogen fluoride) solution for 230 seconds to 270 seconds. Using the process of a wet etching, a sidewall oxide film(15) is then formed. When a liner oxide film is formed, the trench is buried with an HDP(high density plasma) oxide film(17). After planarizing the oxide film, the nitride film is removed. To remove the exposed oxide film, the resultant structure is immersed in the HF solution.

Abstract: A TDD antenna array S-CDMA system for increasing the capacity and quality of a wireless communications is disclosed. By simultaneous exploiting the spatial and code diversities, high performance communications between a plurality of remote terminals and a base station is achieved without sacrificing system flexibility and robustness. The time-division-duplex mode together with the inherent interference immunity of S-CDMA signals allow the spatial diversity to be exploited using simple and robust beamforming rather than demanding nulling. Measurements from an array of receiving antennas at the base station are utilized to estimate spatial signatures, timing offsets, transmission powers and other propagation parameters associated with a plurality of S-CDMA terminals. Such information is then used for system synchronization, downlink beamforming, as well as handoff management. In an examplary embodiment, the aforementioned processing is accomplished with minimum computations, thereby allowing the disclosed system to be applicable to a rapidly varying environment. Among many other inherent benefits of the present invention are large capacity and power efficiency, strong interference/fading resistance, robustness power control, and easy hand-off.
