摘要： A front projection type screen includes a transparent base; a diffusion member formed on one surface of the transparent base; and a retroreflection prism array formed on another surface of the transparent base. Thus, a wide angle of visibility can be secured in a horizontal direction while an angle of visibility in a vertical direction is limited to a narrow scope. Also, a wide viewing angle can be achieved and high efficiency and brightness of light may be obtained.

摘要翻译： 前投影型屏幕包括透明底座; 形成在所述透明基材的一个表面上的扩散部件; 以及形成在透明基底的另一表面上的回射棱镜阵列。 因此，可以在水平方向上确保广角度，同时将垂直方向上的可见度角度限制在窄范围内。 此外，可以实现宽视角，并且可以获得高效率和亮度的光。

摘要： A reflection type compound prism and an optical pickup apparatus employing the same. As a light beam is passed through the compound prism, a size of the light beam in a direction perpendicular to a reference plane is reduced by a first reflection surface, propagated toward an objective lens by second and third reflection surfaces and the size restored by reflecting the light beam from a fourth reflection surface forming an angle less than 45° with respect to the reference plane so that a height of an optical system is reducible to obtain a small thin optical pickup with a desired NA. The second and third reflection surfaces are spaced apart in a direction perpendicular to the reference plane by an amount close to a diameter of the light beam at a point of incidence of the light beam with the compound prism.

The feeding section is movably installed on the tray and includes a slide bar moved between a first and second positions by the bracket, and a bias spring disposed between the try and the slide bar to bias the slide bar toward the first position. At one end of the slide bar, a rack to be engaged with the driving section is formed. The driving section includes a motor for generating a driving power, a second bevel gear rotated by the motor and engaged with the first bevel gear when the slide bar is at the second position, and a loading gear engaged with the rack when the slide bar is at the second position. The shutter of the cartridge is opened without failure outside the optical disc recording and reproducing apparatus, so the optical disc recording and reproducing device has a smaller size, and the loading errors of the disc are prevented.

摘要： A disc drive includes a motor and a turn table mounted on a shaft of the motor to be driven thereby. The turn table includes a lower drive member driven by the motor, and a positioning member mounted on the drive member. The positioning member includes a top surface on which the disc is mounted. The positioning member and drive member form a concave/convex interface, enabling the positioning member to float relative to the drive member to a position wherein the top surface (and disc) is oriented horizontally, even if the drive member becomes tilted relative to the shaft. The interface includes interengaging ridges and grooves to minimize friction and produce a positive rotary drive from the drive member to the positioning member.
