  • Patent number: 4669825
    Abstract: A control apparatus for a reflection mirror of a vehicle is disclosed. The control apparatus is provided with a rear light sensor, an exterior light sensor and a circuit for driving the reflection mirror into a dazzle-free condition when it is detected by the sensors that an intensive rear light is incident from the rear of the vehicle and the exterior of the vehicle is dark. The control apparatus is further provided with a delay circuit which delays driving the reflection mirror into the dazzle-free condition for a predetermined interval of time after the exterior light sensor detects that the exterior of the vehicle is dark. The exterior light sensor may be a switching circuit which switches on and off front light bulbs of the vehicle. The control apparatus is still further provided with a delay circuit which keeps the dazzle-free condition for a predetermined interval of time even after the rear light sensor detects that the rear of the vehicle is dark.

  • Patent number: 4669827
    Abstract: A control apparatus for a dazzle-free reflection mirror of a vehicle is disclosed. The control apparatus is provided with a rear light sensor and a circuit for driving the reflection mirror into a dazzle-free operation in accordance with the intensity of the rear light detected by the rear light sensor when a light switch is turned on. The control apparatus is further provided with a mirror adjusting device for adjusting the reflection angle of the reflection mirror and a detecting circuit for detecting the adjusting operation of the mirror adjusting device. When the detecting circuit detects the adjusting operation, the dazzle-free operation of the reflection mirror is disabled even if intensive light is incident to the reflection mirror from the rear of the vehicle.

  • Patent number: 4669826
    Abstract: In a vehicle having an interior room mirror and a pair of exterior right and left side mirrors, a single photo sensor is provided for detecting an intensity of light incident from the rear of the vehicle. A driving circuit drives both the room mirror and the side mirrors into a dazzle-free condition in common when the photo diode detects the intensive rear light. Alternatively two photo sensors are provided for detecting not only the intensity of the rear light but also direction of the rear light and both the room mirror and one of the right and left side mirrors are driven into the dazzle-free condition in accordance with both the intensity and direction of the rear light.

  • Patent number: 4655549
    Abstract: A reflection mirror using a liquid crystal cell is disclosed. A first thin film consisting of one of magnesium difluoride, silicon dioxide, silicon monoxide or titanium dioxide is formed on a glass substrate supporting the liquid crystal cell and a thin aluminum film is formed on the first thin film as a reflection mirror layer. Adhesiveness of the thin aluminum film to the glass substrate is strengthened by the first thin film. A second thin film is formed on the thin aluminum film to protect the same from being hurt. The reflection mirror may be used as a dazzle-free reflection mirror of an automotive vehicle.

  • Patent number: 4632509
    Abstract: This invention discloses a glare-shielding reflector which controls light reflectance electrically. The present invention provides a glare-shielding type reflector having a photosensor block which can detect an incident angle of a luminous flux to the reflector and a glare-shielding layer which is divided into plural units and driven individually. A glare-shielding layer formed on a front surface of a mirror is divided into plural units and only the specified glare-shielding units are automatically put into a glare-shielding state, according to the incident angle of the luminous flux to the mirror.

  • Patent number: 4623222
    Abstract: A liquid crystal type dazzle-free reflection mirror arrangement which changes reflectivity of the incident light by way of changing the transmittivity of the incident light through a liquid crystal provided within a frame body is disclosed. A semitransparent mirror is positioned behind the liquid crystal and a photo sensor is positioned behind the semitransparent mirror. When the photo sensor detects that the intensity of the incident light passing through the semitransparent mirror, an alternating current electric field is applied to the liquid crystal which responsively decreases the transmittivity of the incident light. A heater for heating the liquid crystal is activated when a door of an automobile is opened and the temperature of the liquid crystal is low.

  • Patent number: 4551669
    Abstract: A packaged solar cell apparatus comprises at least two sunlight electric generating devices, a light intensity detector for producing an output signal in response to the intensity of incident sunlight, a comparator for comparing an output signal level of the light intensity detector with a reference level, and a switch for automatically switching the connection of the plurality of sunlight electric generating devices in accordance with an output signal of the comparator. The connection of the plurality of sunlight electric generating devices is switched between series and parallel connections, respectively, as the output signal level of the light intensity detector becomes higher or lower than the reference level, whereby output electric power from the plurality of sunlight electric generating devices is efficiently supplied to a desired electric load in accordance with the intensity of insolation.

  • Patent number: 4499451
    Abstract: A mirror arrangement including a transparent glass member, a translucent film behind the glass member, a light generating element having a configuration for conveying information when activated, the mirror arrangement functioning as an ordinary mirror when no voltage is applied to the light generating element such as an electroluminescent element while functioning as a light source or display panel when the voltage is applied to the light generating element, since the element energized emits light through the translucent aluminum film and the glass in front.
