Title: Multi-channel audio enhancement system for use in recording and playback and methods for providing same
Inventor: KRAEMER ALAN D
IPC: H04S5/02
Filed: 1997-10-31
Abstract: PURPOSE: A multi-channel audio enhancement system for use in recording and playback and methods for providing same is provided to improve surround sound by using an audio system which receives a group of multi-channel audio signals and to realize a simulated surround sound environment through playback of only two output signals. CONSTITUTION: An audio enhancement system and method for use receives a group of multi-channel audio signals and provides a simulated surround sound environment through playback of only two output signals. The multi-channel audio signals comprise a pair of front signals intended for playback from a forward sound stage and a pair of rear signals intended for playback from a rear sound stage. The front and rear signals are modified in pairs by separating an ambient component of each pair of signals from a direct component and processing at least some of the components with a head-related transfer function. Processing of the individual audio signal components is determined by an intended playback position of the corresponding original audio signals. The individual audio signal components are then selectively combined with the original audio signals to form two enhanced output signals for generating a surround sound experience upon playback.

Abstract: PURPOSE: A serial processing method using a dual platen of an ion implanting equipment is provided to improve process capability by removing a loading/unloading time and reduce a consumable part by improving effect of a serial process in a semiconductor manufacturing method. CONSTITUTION: A wafer(30) is moved by using a platen to implant ions to the wafer. The platen is divided into a left platen(10) and a right platen(20). The wafer is loaded on a load-lock. The wafer is mapped and an orientation is executed. The ions are implanted to the wafer. The wafer is unloaded on the load-lock. The left platen and the right platen are structured to be capable of rotating by 45 degrees. As a result, the left platen and the right platen are easily moved to an implanting target in a selective manner. Further, processing effect is improved, such that consumable part is reduced. Since the two platens(left and right platens) are used in contrast to the conventional art where one platen is used, a wafer loading/unloading time is eliminated in the platens in the process times. Accordingly, it saves by 4 seconds per wafer.

Title: structure for burner-cap in gas burner
Inventor: KIM HYEONG JONG
IPC: F23D14/78
Filed: 2000-04-12
Abstract: PURPOSE: Burner cap structure of a gas burner is provided to prevent remaining gas from flowing back in a process of igniting flames and to form regular flames by inhibiting the excess amount of mixed gas from being injected. CONSTITUTION: Plural elongated portions(111) are formed at the end of each irregular portion(110) of a burner head(100). The elongated portion has thickness(T1) relatively thinner than one(T2) of each irregular portion, and the end is extended to a specific length toward the inner center of the burner head. Thereby, the forming length of each flame hole(112) becomes longer without extension of each irregular portion toward the inside of the burner head. Herein, the flame holes are formed by each irregular portion. As the gas flow path from the flame holes becomes longer, the entire temperature over the flame holes falls. In addition, the gas is ignited in a process of flowing flames. Therefore, the burner cap structure of a gas burner prevents the flame from being in contact with the remaining gas at the lower part of the burner head. The burner cap structure is formed in multi-step type to shorten a distance(H1) between the elongated portions and a distance(H2) between the irregular portions temporarily. Thus, the injection speed of gas is reduced.

The dissolved surfactant is added to an attenuated lipid A derivative to obtain a mixture. The molar ratio of attenuated lipid A derivative to surfactant in the mixture is about 4:1. The solvent is evaporated and water is added to the resulting film. The suspension is sonicated in a 60 °C water bath until it becomes clear. Animals administered the adjuvant formulation exhibited increased antibody responses to a given antigen as well as displayed enhanced lymphocyte proliferative and cytotoxic T- lymphocyte responses. Intranasal administration of the aqueous adjuvant composition and an antigen stimulates the production of serum and mucosal secreted IgA.

Abstract: 본 발명은 전처리공정을 거치면서 패턴의 형성이 완료된 웨이퍼를 단위칩으로 소잉할 때 사용하는 반도체 소잉장치의 소잉휠에 관한 것으로, 웨이퍼, 또는 매트릭스타입으로 몰딩된 리드프레임 등을 소잉시 동시에 복수개의 라인을 따라 소잉이 이루어지도록 하여 개별 칩, 또는 단위품으로의 분리가 신속하게 이루어질 수 있도록 한 것이다. 
     이를 위해, 모터의 구동에 따라 회전하는 회전축(110)과, 상기 회전축(110)에 장착되는 소잉휠을 구비한 반도체 소잉장치에 있어서, 상기 회전축(110)의 일측에 장착되는 복수개의 제 1 소잉휠(121)과, 상기 회전축(110)의 타측에 제 1 소잉휠과 일정 간격이 유지되게 장착되는 복수개의 제 2 소윙휠(122)과, 상기 제 1, 2 소잉휠의 하방에 360°방향 전환 가능하게 설치되어 웨이퍼가 로딩되는 테이블(40)로 구성된 것이다.
