    • The present invention provides an inexpensive projection display that allows a pixel grid as ineffective portions of respective pixels of a light valve to be made inconspicuous. The projection display includes a birefringent element (43) for spatially separating light from a transmission liquid crystal light valve (39). The birefringent element (43) includes a first birefringent plate (40) that the light from the liquid crystal light valve (39) enters, a second birefringent plate (41) that light from the first birefringent plate (40) enters, and a third birefringent plate (42) that light from the second birefringent plate (41) enters. A polarization direction of the light entering the first birefringent plate (40) forms an angle of n×45° (n is an integer other than 0) with an optic axis of the first birefringent plate (40) projected on an incident surface of the first birefringent plate (40). An optic axis of the second birefringent plate (41) projected on an incident surface of the second birefringent plate (41) is orthogonal to the optic axis of the first birefringent plate (40) projected on the incident surface of the first birefringent plate (40). An optic axis of the third birefringent plate (42) projected on an incident surface of the third birefringent plate (42) extends horizontally or vertically.

    • A method for collecting log information relating to specific processing from pieces of log information for integration is disclosed. Session information, which is given every time log information is processed and included in the log information held by a server, is recorded in a session-information management table. In addition, how session information associates with others among different pieces of log information is recorded in a session-information association table. Recursively searching the session-information association table by use of session information specified by a user through a target log entry input unit enables identification of a set of session information relating to the processing to which the user pays attention. Information corresponding to each of the session information related is collected from log information, and is integrated according to the recorded data and time of a log.
    • 公开了一种用于从用于集成的日志信息的集合中收集与特定处理有关的日志信息的方法。 会话信息被记录在会话信息管理表中,每次日志信息被处理并包含在由服务器保存的日志信息中时。 此外,会话信息关联表中记录有如何将会话信息与不同日志信息中的其他信息相关联。 通过使用由用户通过目标日志条目输入单元指定的会话信息递归地搜索会话信息关联表,能够识别与用户关注的处理有关的一组会话信息。 从日志信息收集与每个会话信息相对应的信息,并根据日志的记录数据和时间进行积分。

    • A white light beam from a light source portion (201) is separated into respective light beams of red, green and blue by a color separation optical system (204). The respective light beams are reflected by a rotating polygon mirror (207), travel via a second optical system (210) and form belt-like illuminated regions on an image display panel (212). By a rotation of the rotating polygon mirror (207), the illuminated regions of the respective light beams move continuously, and each pixel of the image display panel (212) is driven by a signal corresponding to a color of light entering this pixel. An image on the image display panel (212) is magnified and projected onto a screen by a projection optical system (216). The color separation optical system (204) has first and second reflecting mirrors that respectively reflect the respective light beams of red, green and blue, and these reflecting mirrors are arranged so that optical paths of the respective light beams have equal lengths from the light source portion (201) to the rotating polygon mirror (207). This makes it possible to provide a small projection-type image display apparatus that has a high efficiency of light utilization and can display an image with high resolution and enhanced color uniformity.
    • 来自光源部分(201)的白色光束通过分色光学系统(204)分离成各种红色,绿色和蓝色的光束。 各个光束被旋转的多面反射镜(207)反射,经由第二光学系统(210)行进,并在图像显示面板(212)上形成带状照射区域。 通过旋转多面反射镜(207)的旋转,各光束的被照射区域连续移动,并且通过与进入该像素的光的颜色对应的信号来驱动图像显示面板(212)的每个像素。 通过投影光学系统(216)将图像显示面板(212)上的图像放大并投影到屏幕上。 分色光学系统(204)具有分别反射红色,绿色和蓝色的各个光束的第一和第二反射镜,并且这些反射镜被布置成使得各个光束的光路具有与光源相同的长度 部分(201)连接到旋转多面镜(207)。 这使得可以提供具有高效率的光利用的小投影型图像显示装置,并且可以以高分辨率和增强的颜色均匀性显示图像。

    • An information retrieval system with good human-interface methods to give the system ease-of-use having two distinctive features with the first being visual interface and the second being natural language interpretation. The visual interface provides for one is visual interaction for local search and natural language interpretation provides for linguistic interaction for global search. The visual interface provides versatile views onto the contents of the knowledge base that the system has, controlling mechanisms for browsing through the knowledge base, a capability of showing relevant information for the users, and a mechanism for editing a query expression that describes information to retrieve. By using the visual interface for information retrieval, the users can easily create query expressions, by consulting and reacting with the system. The natural language interpretation makes use of a conceptual network as a knowledge-base that stores important concepts and relationships among these concepts. Based on knowledge and information represented in the conceptual network, the meaning of a noun phrase or a nominal compound which is a string of adjectives and nouns with some prepositions can be inferred. The inferred interpretation of such a noun phrase is paraphrased into an expression that the information retrieval system can handle. Therefore, the user of the system can simply describe the desired information in a language to get the desired information.
    • 一种具有良好人机界面方法的信息检索系统,使系统易用性具有两个独特的特征,第一个是视觉界面,第二个是自然语言解释。 视觉界面提供一个是用于本地搜索的视觉交互和自然语言解释,为全球搜索提供语言交互。 视觉界面提供了系统具有的知识库内容的多种视图,控制浏览知识库的机制,显示用户相关信息的能力,以及编辑描述要检索的信息的查询表达式的机制 。 通过使用可视化界面进行信息检索,用户可以通过与系统进行协商和反应,轻松创建查询表达式。 自然语言解释使用概念网络作为存储这些概念之间的重要概念和关系的知识库。 基于概念网络中所代表的知识和信息,可以推断名词短语或名词复合词的含义,它是具有一些介词的形容词和名词串。 这种名词短语的推断解释被转换成信息检索系统可以处理的表达式。 因此,系统的用户可以简单地用语言描述期望的信息以获得期望的信息。
