Abstract:
To obtain a light reflecting component having high reflection surface accuracy, a resin film (1) with a surface shaped to reflect light as shown in the figure is set to a swell (4) formed on a male mold (3a) of a shaping mold (3) assembled to a clamp mechanism of an injection molding machine, not shown, and after the mold (3) is sealed, a molten resin (6) is charged into a space defined between male and female molds (3a and 3b).
Abstract:
A system for affording panoramic forward, side and rear views to operators of a wide range of transportation means for facilitating safe maneuvering. The system includes a plurality of bi-directional mirror assemblies (106, 116) each having a first mirror (104, 118) and a second mirror (108, 120), such that the first mirror and the second mirror subtend a predetermined angle therebetween.
Abstract:
An all-polymeric cold mirror which reflects visible wavelengths while transmitting a substantial portion of infrared wavelengths is provided. The mirror includes a sufficient number of alternating layers of at least first and second diverse polymeric materials such that at least 50 percent of peak reflecting visible light of a wavelength of between 380 to 680 nm incident on the mirror is reflected and at least 50 percent of infrared light between 680 to 2000 nm is transmitted or absorbed. The mirror may be designed so that it either reflects or absorbs ultraviolet light.
Abstract:
A photocoupler used for splitting signal light in an optical transmission line at a predetermined ratio. A substrate is provided with a single-layer beam splitter formed by vacuum depositing a film material having a refractive index below a square root of the refractive index of the substrate so that an optical film thickness attains a predetermined value, and means for holding the single-layer beam splitter in the optical transmission line so that the angle of incidence is kept at about 45 . Alternatively, four-, five- or seven-layered thin film is formed by using three kinds of film materials having refractive indices of 1.46 +- 0.10, 1.65 +- 0.10 and 2.30 +- 0.10, respectively, on a substrate having a refractive index of 1.51 +- 0.10 or 3.50 +- 0.20, and the combination of the thin film layers and the optical film thickness of each thin film layer are selected so that dependence of a split ratio on polarized wave becomes small, and a branching film can be formed. The photocoupler further includes this beam splitter and means for holding the beam splitter in the optical transmission line at an angle of about 45 . Furthermore, the photocoupler may comprise a beam splitter formed by forming 4- to 14-layered thin film layer using two kinds of film materials having refractive indices of 1.46 +- 0.10 and 2.30 +- 0.10 on a substrate having a refractive index of 1.51 +- 0.10 to 3.50 +- 0.20 and selecting the combination of the thin film layers and the optical film thickness of each layer so that the dependence of the split ratio on polarized wave becomes small, and means for holding the beam splitter in the optical transmission line at an angle of about 45 .
Abstract:
The present invention relates to a method for designing the surface of rearview mirror for vehicle, which may effect wide-view and blindspot-free. The method includes: establishing the simulating models of driver's eye, the rearview mirror and the rearview-field; finding the optical relation between the surface shape of said rearview mirror and the driver's view-area by testing with the aid of a reflector having deformable surface shape; and determining the rearview mirror surface shape according to the result of said test. The present invention further relates to an algorithm for computing surface shape of the rearview mirror by simulating optical relation of driver's eye, the mirror and the rearview-field. The present invention also relates to a reflector means having deformable surface and used to above test. Said means comprises a plurality of mirror units, these mirror units being independent, and their spatial positions being adjusted.
Abstract:
An external rear-view mirror assembly (10) for commercial vehicles having a support arm (12) and brackets (18) for mounting the support arm to a motor vehicle. A housing (20) having a back member (22), a front member (24) and an interior volume (30) between the back and front members. The support arm extends longitudinally through the interior volume. At least one support plate (32) is removably attached directly to the support arm. An adjustable mirror assembly (58) is mounted to the front side of the support plate and is variably positionable within an open chamber (52) of the front member. A release mechanism (81) is configured on the back surface of the back member of the housing for releasably attaching the back member directly to the front member of the housing without interfering with other components of the rear-view mirror assembly.
Abstract:
A true image mirror consisting of two mutually perpendicular reflecting panels connected to a third non-reflecting panel parallel to the observer. The resulting assembly forms a right-angled triangular prism together with two flat triangular portions. The front panel consist of a central window for framing the resulting image. Said window may be filled with a transparent glass pane or a magnifying lens. The prism may be housed in a frame or cabinet and provided with lamps for illuminating the observer, and is suitable for displaying objects or persons located inside the prism.
Abstract:
A new mirror structure (18) is based upon a composite resin laminate. The mirror surface (20) is provided by a gel coat resin layer (8) that has been applied to a forming tool (2) which has an optical quality surface (4), and a shape complementary to the desired mirror shape. The gel coat resin layer is cured so that it replicates the optical quality surface of the forming tool, and a rigid composite backing (10, 12, 14, 16) is then built up over its rear surface. A reflective metal coating (34, 42) is applied to the mirror's resin surface, either with a conventional vacuum deposition or with a new process. In the new process the microporous resin surface (20) is first degreased and cleaned, followed by the application of a bonding material (28) which extends into the resin micropores (22), and a conventional Brashear process to precipitate a silver coating (34, 42) onto the resin. The metal coating can be applied either after the resin layup has been completed, or it can be integrated into the layup process.
Abstract:
A mirror assembly (10) for displaying true images of objects located in front of the mirror. The mirror has two substantially plane reflecting surfaces (12, 14) arranged to intersect each other at an angle of approximately ninety degrees, the reflecting surfaces are supported by a first pair of side walls (26, 28). A second pair of side walls (22, 24) are disposed at approximately right angles to the first pair of side walls and define between them a view opening (32) for viewing true images and for simultaneously blocking the view of extraneous images.
