    • A high contrast lenticular lens sheet that can improve the brightness of an image and the angle of visibility. When it is assumed that P represents the pitch of the lens element and H represents the width of the black stripe portion as viewed in a cross section perpendicular to the lens element, the difference F in height between the black stripe portion and the lens element is set to have a range that is expressed by the inequality: 0.098 P≦F≦(P−H)/2 tan(π/3). Simultaneously, the width B as measured from an apex portion of the black stripe portion in regard to a colored portion on a side wall of the black stripe portion is set to have a range that is expressed by the inequality: 0.30 F≦B≦0.89 F.

    • An intake flow control apparatus for an internal combustion engine eases operation of an air flow regulator and permits use of a short intake passage, thus providing a high output. The intake flow control apparatus includes an air routing member having an intake passage formed therein, and an air flow regulator opposed to an upstream-side opening of the intake passage. The air flow regulator moves in an intake axis direction while being guided by a light-weight guide structure to control the amount of intake air supplied. The air flow regulator may include plural valve elements different in operation timing, in which a valve actuator successively actuates the plural valve elements in accordance with a throttle operation to control the amount of intake air. The apparatus also includes a vacuum moderating structure for reducing the effective strength of a vacuum applied to the air flow regulator.

    • A lens sheet capable of preventing reflection of extraneous light without decreasing extraneous light absorption, having extraneous light absorbers that can be readily formed by printing and are scarcely stained. The present invention also provides a rear projection screen including such a lens sheet. A rear projection screen has a Fresnel lens sheet and a lenticular lens sheet placed on the viewing side of the Fresnel lens sheet. The lenticular lens sheet has lenses formed on those portions of the light-emergent-side surface of the sheet-shaped substrate part through which light converged by other lenses pass, and extraneous light absorbers formed on those portions of the light-emergent-side surface of the sheet-shaped substrate part through which light converged by the other lenses does not pass. Each extraneous light absorber includes a black-colored binder resin and a number of light-diffusing particles subjected to coloring treatment, incorporated in the binder resin.
    • 一种能够防止外来光的反射而不减少外部光吸收的透镜片,具有能够通过印刷容易地形成并且几乎不被染色的外来光吸收剂。 本发明还提供一种包括这种透镜片的背投屏幕。 背投屏幕具有​​菲涅尔透镜片和放置在菲涅尔透镜片的观看侧的双凸透镜片。 双凸透镜片具有形成在片状基板部的发光侧表面的其他透镜会聚的光的那些部分上的透镜,以及形成在发光侧表面的那些部分上的外来光吸收体 通过其它透镜会聚的光不会通过的片状基板部分。 每个外来光吸收剂包括黑色粘合剂树脂和许多经过着色处理的光漫射颗粒结合在粘合剂树脂中。

    • To effectively reduce noise caused by an attachment part of a cam chain guide without increasing a pressing force of a cam chain tensioner more than is necessary. A cam chain guide for slidably guiding a cam chain at a valve gear of a four cycle engine is made of resin. An attachment hole for an attachment bolt is provided at an attachment end section for the crankcase. Side surface projections are provided equally spaced at the periphery of an attachment surface surrounding the attachment hole so as to project from a normal surface. Annular recesses are formed at the peripheries of each of the side surface projections. Furthermore, inner surface projections are provided at the inner peripheral surface of the attachment hole equally spaced about the periphery so as to project in a central direction.
