    • The present system relates to a system architecture that uses a single electron transistor (SET) to analyze base sequences of deoxyribonucleic acid (DNA) at ultra high speed in real time. DNA represents the entire body of genetic information and consists of nucleotide units. There are a total of four types of nucleotides, and each nucleotide consists of an identical pentose (deoxyribose), phosphate group, and one of four types of bases (Adenine: A, Guanine: G, Cytosine: C, Thymine: T). A and G are purines having a bicyclic structure while C and T are pyrimidines having a monocyclic structure. Each has a different atomic arrangement, which signifies a different charge distribution from one another. Therefore, a system comprising a single electron transistor that is very sensitive to charges, a probe of a very small size that reacts to one nucleotide very effectively, and an extended gate that connects the SET with the probe, can be used to analyze DNA base sequences at ultra high speed in real time.
    • 本系统涉及使用单电子晶体管(SET)实时分析超高速脱氧核糖核酸(DNA)的碱基序列的系统架构。 DNA代表整个遗传信息,由核苷酸单位组成。 总共有四种类型的核苷酸,每个核苷酸由相同的戊糖(脱氧核糖),磷酸基和四种碱基之一(腺嘌呤:A,鸟嘌呤:G,胞嘧啶:C,胸腺嘧啶)组成。 A和G是具有双环结构的嘌呤,而C和T是具有单环结构的嘧啶。 每个都具有不同的原子排列,这表示彼此不同的电荷分布。 因此,可以使用包括对电荷非常敏感的单电子晶体管的系统,非常有效地对一个核苷酸反应的非常小的尺寸的探针和将SET连接到探针的扩展的门来分析DNA碱基 实时超高速序列。

    • A polarizing element used for LCD projectors or LCD monitors, which includes a polarized beam separating and composing prism and either a twisted nematic (TN) liquid crystal or an 1/2 or 1/4 wavelength plate, thereby being capable of not only doubling the efficiency of the light source, but also obtaining a uniform intensity of light. The polarized beam separating and composing prism serves to transmit light beams being parallel to the polarization direction of the polarizer therethrough while shielding light beams being non-parallel to the polarization direction of the polarizer. With such a construction, it is possible to double the light efficiency while using the same light source. Where the polarizing element is applied to an optical system, certain elements of the optical system such as a reflecting mirror and condenser lens can have a reduced size which corresponds to 1/2 of the size of each LCD panel. Accordingly, it is possible to achieve an easy design and a uniformness in the intensity of composed light beams resulting in an increase in light efficiency.
    • 用于LCD投影仪或LCD监视器的偏振元件,其包括偏振光束分离和组成棱镜以及扭转向列(TN)液晶或+ E,fra 1/2 + EE或+ E,fra 1/4 + EE波长板,从而不仅可以使光源的效率加倍,而且可以获得均匀的光强度。 偏振光束分离和组合棱镜用于透射平行于偏振片的偏振方向的光束,同时屏蔽与偏振器的偏振方向不平行的光束。 通过这样的结构,可以在使用相同的光源的同时使光效倍增。 在将偏振元件应用于光学系统的情况下,诸如反射镜和聚光透镜的光学系统的某些元件可以具有对应于每个LCD面板的尺寸的+ E,fra 1/2 + EE的减小的尺寸。 因此,可以实现简单的设计和组合光束的强度的均匀性,导致光效率的提高。
