摘要： A protective sleeve for a spark plug includes a center electrode, an insulator, an attachment fitment having an attachment screw section formed on an outer peripheral surface thereof, and a ground electrode. A protective sleeve is disposed in a detachable manner on the outer periphery of the attachment screw section. The attachment fitment includes a flange section that has a diameter larger than that of the attachment screw section on a base end side of the attachment screw section. The protective sleeve includes a main body cylinder section having an inner diameter that is the diameter of the attachment screw section or larger, and smaller than the diameter of the flange section, a large diameter cylinder section having an inner diameter that is the diameter of the flange section or larger, and a step section formed between the large diameter cylinder section and the main body cylinder section.

摘要： A holographic screen for displaying images by diffracting and dispersing an image beam projected by an image projector comprises a main hologram for diffracting and dispersing an incident image beam from one of an upward angle and a downward angle, and a directional dispersion hologram, disposed on an image projector side of the main hologram, for dispersing and transmitting part of the image beam within a predetermined angle range centered on a direction of incidence thereof, and directly transmitting another part of the image beam, thereby providing a holographic screen that can maintain the brightness and improve the color reproducibility of a displayed image.
摘要翻译：用于通过衍射和分散由图像投影仪投射的图像束来显示图像的全息屏幕包括用于衍射和分散来自向上角度和向下角度之一的入射图像束的主全息图以及定向色散全息图主要全息图的图像投影仪侧，用于将图像束的一部分分散和传输在以其入射方向为中心的预定角度范围内，并直接传输图像束的另一部分，从而提供可保持亮度的全息屏幕并提高显示图像的颜色再现性。

摘要： An image display device comprising a holographic screen and an image projection device for projecting an image beam onto the holographic screen at an upward or downward angle is provided, wherein a forward view color difference &Dgr;u′v′ between a chromaticity value (u′, v′) at the center of the holographic screen when a white image is projected onto the holographic screen by the image projection device and a standard chromaticity value (u′o, v′o) is 0.04 or less when the projection angle of the image beam onto the center of the holographic screen is set to any angle within a specified projection angle range of 20 to 45°, whereby a image display device and holographic screen can be provided wherein the range of the projection angle of the image beam, in which an image with excellent color reproducibility can be displayed, is wide.
摘要翻译：提供一种图像显示装置，其包括全息屏幕和用于以向上或向下的角度将图像束投影到全息屏幕上的图像投影装置，其中在色度值（u'，v）之间的前视色差Deltau'v' '）在全息屏幕的中心处，当图像投影装置将白色图像投影到全息屏幕上时，并且当图像束的投影角度（u'o，v'o）为0.04或更小时，标准色度值在全息屏幕的中心上设置在20至45°的指定投影角度范围内的任何角度，由此可以提供图像显示装置和全息屏幕，其中图像束的投影角度的范围，其中具有优异色彩再现性的图像可以显示，宽。
