    • The projection-type color display device of the invention includes: a white light source; a splitting means for splitting white light emitted from the white light source into a first, a second, and a third beam having respectively different wavelength regions; a modulation means for modulating the first, the second and the third beams; an irradiation means for irradiating the first, the second and the third beams onto a principal surface of the modulation means at respectively different angles; and a projection means for projecting the first, the second and the third beams modulated by the modulation means. In the projection-type color display device, the first beam includes a color beam having a weakest intensity among the beams in three primary colors contained in the white light; and a direction of the first beam incident onto the principal surface of the modulation means is closer to a normal of the principal surface of the modulation means as compared with the second and the third beams.

    • Particles of a lens coating material for forming a primary film are deposited from a direction toward which the surfaces of the lens prisms of a Fresnel lens face. Next, a light absorbing film is formed, conventionally, by sputtering, on both the lens surfaces on which the previously deposited primary film was formed and on the non-lens surfaces (on which no primary film was formed). This light absorbing film is intended to absorb types of undesirable or "invalid" light (e.g., "flaring light"). Subsequently, the films are removed from only the lens surfaces. Accordingly, a Fresnel lens having "invalid" light absorbing films only on the non-lens surfaces is more easily fabricated within a shorter time and at a reduced cost. Moreover, it is also possible to reduce the generation of "cone" and "rainbow" effects caused by "flaring light" when the Fresnel lens is used as a field lens of a projection-type image display device.
    • 用于形成初级膜的透镜涂层材料的颗粒从菲涅尔透镜的透镜棱镜的表面面向的方向沉积。 接下来,通常通过溅射形成在其上形成预先沉积的初级膜的透镜表面和非透镜表面(其上没有形成初级膜)的光吸收膜。 这种光吸收膜旨在吸收不期望的或“无效”的光(例如“燃烧的光”)的类型。 随后,仅从透镜表面去除膜。 因此,仅在非透镜表面上具有“无效”的光吸收膜的菲涅耳透镜更容易在更短的时间内以更低的成本制造。 此外,当将菲涅耳透镜用作投影型图像显示装置的场透镜时,还可以减少由“扩光”引起的“锥”和“彩虹”效应的产生。

    • A throttle actuator comprising: a body which forms an intake passage; a throttle valve shaft; a throttle valve which is connected to the throttle valve shaft and which adjusts the opening of the intake passage; and a motor which applies torque to the throttle valve shaft. The throttle valve is provided with: a valve shaft lever; an accelerator lever which is operated by means of the accelerator pedal; a floating lever which is positioned between the valve shaft lever and the accelerator lever and which transmits torque to the valve shaft lever in such a direction that the throttle valve opens; a valve returning spring which applies torque to the throttle valve shaft in such a direction that the throttle valve closes; a coupler spring which pulls the accelerator lever and the floating lever toward each other; and an accelerator lever returning spring which applies torque to the accelerator lever in such a direction that the throttle valve closes. A difference between the amount of operation caused by the action of the accelerator pedal and the amount of operation caused by the motor is offset by the relationships between the set positions of floating lever and the coupler spring and between the set positions of the floating lever and the valve shaft lever.
