    • A projector is provided wherein the shapes of rod integrators for the respective colors (i.e., the shapes of the output ports thereof) are made nearly the same as the shapes of the effective pixel regions and the sizes of the output ports of the rod integrators for the respective colors are made slightly larger than the sizes of the effective pixel regions of the liquid crystal light valves opposed thereto. As a result, uniform illumination light output from the output ports can be caused to enter the effective pixel regions with no loss or damage to uniformity.
    • 提供一种投影仪,其中用于各种颜色的棒积分器的形状(即,其输出端口的形状)几乎与有效像素区域的形状和棒状积分器的输出端口的尺寸相同,用于 使各个颜色略大于与其相对的液晶光阀的有效像素区域的尺寸。 结果,可以使从输出端口输出的均匀的照明光进入有效像素区域,而不会损失或损坏均匀性。

    • A brake structure of a traction machine includes a brake drum which is made rotatable about a shaft disposed on a rotary axis of the traction machine, and an electromagnetic brake unit built in an inner space of the brake drum. The electromagnetic brake unit includes a plurality of movable iron cores, a plurality of brake shoes located on the outside of the individual movable iron cores and joined thereto by connecting members, the brake shoes having curved outer surfaces facing a curved inner surface of the brake drum, and a one-piece formed stationary iron core block. The one-piece formed stationary iron core block has a plurality of stationary iron core portions joined to the individual movable iron cores via compression springs for forcing the individual brake shoes against the curved inner surface of the brake drum via the movable iron cores and the connecting members.

    • An exhaust emission control system for an internal combustion engine having nitrogen oxides removing device provided in an exhaust system of the engine for removing nitrogen oxides in exhaust gases and an oxygen concentration sensor provided downstream of the nitrogen oxides removing device for detecting the concentration of oxygen in the exhaust gases. Deterioration of the nitrogen oxides removing device is determined on the basis of an output of the oxygen concentration sensor after the air-fuel ratio has been changed from the lean region to a rich region with respect to the stoichiometric ratio. Abnormality of the oxygen concentration sensor is determined on the basis of an output of the oxygen concentration sensor during a period in which the air-fuel ratio is kept in the rich region with respect to the stoichiometric ratio immediately after execution of the deterioration determination of the nitrogen oxides removing device.
    • 一种用于内燃机的废气排放控制系统,其具有设置在用于除去废气中的氮氧化物的发动机的排气系统中的氮氧化物除去装置,以及设置在氮氧化物除去装置的下游的氧浓度传感器,用于检测氧浓度 废气。 氮氧化物除去装置的劣化是根据空燃比从稀薄区域向化学计量比变化为浓区域之后的氧浓度传感器的输出而求出的。 基于氧浓度传感器的输出,在空气 - 燃料比保持在富区域的时间段内,相对于执行劣化判定之后的化学计量比来确定氧浓度传感器的异常 氮氧化物去除装置。
