  • Patent number: 6959994
    Abstract: To provide a camera built-in type rearview mirror device with illumination, wherein rigidity of the mirror housing can be raised, the camera main body part can photo a clear picture by extensive photographing feasible viewing angle through a transparent cover, and built-in of the camera module is simple. Mirror housing 2 includes concave part 2C formed in an opening manner downwardly which is arranged in the vicinity of photographing window 2B where lens 5B of the camera main body part 5A is faced, and capable of accommodating an illumination light source. For this reason, opening area of the photographing window 2B is decreased. Also, the circumference of the photographing window 2B is reinforced by the cross-sectional box type form of the concave part 2C. Especially a bulge part with circular curved section is formed so that the lens of the camera main body part may rush in, to thereby decrease the opening area of the photographing window further. Then rigidity of the mirror housing 2 is further raised.

  • Patent number: 6950221
    Abstract: An electrically conductive metallic clip used for lead-out electrodes of an EC mirror has all-shaped section. One of an opposed side pieces of the clip is disposed at the side of an electrically conductive film and is formed in a planar shape. The other side piece disposed at the side of a glass substrate is configured in a curved shape and has a terminal that is outwardly round-opened. A central portion of the other side piece is formed in a convex shape so that an opening thereof is narrowed. When a sealing resin expands, an occurrence of poor contact between a lead-out electrode portion and the clip is prevented. Moreover, good workability for attaching the clip to the substrate is realized. Furthermore, the lead-out electrode is prevented from being damaged. Additionally, the clip is prevented from being deformed when the clip is fitted onto the substrate.

  • Patent number: 6940404
    Abstract: An RF converter circuit 11 that constitutes a video signal superposing/power deriving unit 100 converts video signals generated from images taken by a surveillance camera 10, which derives a direct current voltage as a driving power from an antenna lead-in wire 6 through a filter circuit (LPF circuit 12), to radio-frequency signals. The radio-frequency signals are transmitted through the antenna lead-in wire 6 to a television receiver 2. Images taken by the surveillance camera 1 can be viewed on the television receiver 2 only by selecting the channel assigned to the surveillance camera 1. Accordingly, the driving power for the surveillance camera 1 is not relied upon a solar battery or secondary batteries, and wiring work therefor may be simplified.

  • Publication number: 20050099149
    Abstract: As a vertical motion motor (M2) comprised of a brushless motor is driven to rotate in response to a control signal from a main controller (10), a pulse signal generated with the shape corresponding to the number of rotations of the vertical motion motor (M2) is counted by a pulse signal count unit of the main controller (10). Feedback control is exercised over the number of rotations of the vertical motion motor (M2) in accordance with a count value (the number of counts) of the pulse signal, so that mirror surface orientation of a door mirror (2) can be accurately adjusted to tilt downward to a predetermined set angle, and to tilt upward back to a home position angle. A mirror angle control apparatus (1) is provided with high durability and reliability, which can exercise accurate control for a long period of time.
