  • Publication number: 20140233124
    Abstract: The need for an O ring cover is eliminated when a gap between a shaft portion of a mover for mirror surface angle detection and a hole in a sensor case is sealed using an O ring. An O ring that allows a shaft portion of a slide block to be inserted therethrough is interposed between a sensor case and an actuator housing. The sensor case and the actuator housing are interconnected by means of screw-fastening via screws, and the O ring is brought into pressure contact with and held between the sensor case and the actuator housing by means of the screw fastening forces.

  • Patent number: 8770769
    Abstract: The present invention has an object to provide a door mirror for an automobile in which a variation in a gap between a bottom wall of a housing and a pedestal portion of a door-mirror base is eliminated. In this door mirror for an automobile, even if distortion, contraction error or the like occurs in a lower housing after molding, if the frame and the shaft are assembled rotatably with accuracy, since a lower end face of a shaft container portion provided on the frame rotatably connected to the shaft fixed to a pedestal portion of the door-mirror base is in contact with the peripheral edge portion of an opening portion in the inner face of a bottom wall of the lower housing, the housing can be fixed to the frame without an error in the positional relationship between the peripheral edge portion of the opening portion of the lower housing and the shaft.

  • Publication number: 20140177249
    Abstract: While a light source is arranged on the back side of a light guide lens, light beams can be emitted from the light source with respective optical axes directed in one direction and be guided toward opposite ends of the light guide lens. A light source and a reflective surface are arranged on the back side of a light guide lens. The light source emits light beams with respective optical axes directed in one direction. One of the light beams obliquely enters the light guide lens toward one end in a long direction of the light guide lens without being reflected by the reflective surface. Another one of the light beams is reflected by the reflective surface and obliquely enters the light guide lens toward another end in the long direction of the light guide lens.

  • Patent number: 8599259
    Abstract: To facilitate discrimination of a curb, a gutter or the like by using an infrared illuminating device and an infrared-sensitive image pickup device mounted on an exterior mirror of a vehicle when the vehicle is pulled over to a shoulder at night. Two illuminating devices having optical axes oriented downward are mounted on a housing of a side mirror at a distance from each other in the lateral direction of a vehicle. The illuminating devices alternately emit infrared light downwardly. An image pickup device sensitive to infrared light having an optical axis oriented downward is mounted on the housing at a middle position between the left and right illuminating devices. An image taken by the image pickup device is displayed on an image monitor disposed at a position where the monitor can be viewed from the driver seat.

  • Patent number: 8599037
    Abstract: The door mirror for an automobile including a light diffusing section disposed between the side object detection symbols and the first and second LEDs. Relative dispositions between the side object detection symbols and the first and second LEDs are such that the optical axis of the first LED intersects with a host vehicle display section and the optical axis of the second LED intersects with an other vehicle display section. The relative dispositions enable uniform illumination of the side object detection symbols using the two LEDs. Furthermore, the optical axis of the first LED intersects with a light non-transmissive portion of the host vehicle display section and the optical axis of the second LED intersects with a light non-transmissive portion of the other vehicle display section.

  • Patent number: 8550641
    Abstract: A manually retractable vehicle door mirror which can reduce the number of parts and improve efficiency of assembly operations as well as provide large bearing capacity at a location outwardly away from a shaft location to bear bending moments acting on a housing support member due to external forces. A housing support member is formed integrally with a shaft, annular wall, and a housing-support-member-side portion of a clutch, which are placed coaxially with a rotation axis. A housing is fixedly coupled to the housing support member. A base is formed integrally with a shaft passage hole, annular wall housing groove, and a base-side portion of a clutch, which are placed coaxially with a rotation axis. The shaft is rotatably inserted into the shaft passage hole, the annular wall is rotatably housed in the annular wall housing groove, and the housing support member is supported on the base in such a way as to be able to rotate around the rotation axis.

  • Patent number: 8536111
    Abstract: The present invention provides a hydrophilicity-restoring agent for removing inorganic matter from a hydrophilic surface whose hydrophilicity has been reduced by the adhesion of the inorganic matter to thereby restore the hydrophilicity of the hydrophilic surface, and provides a method for restoring the hydrophilicity of a hydrophilic surface using the hydrophilicity-restoring agent. A gel of a hydrophilicity-restoring agent is prepared by mixing a thickener such as polyethylene glycol and xanthan gum with an aqueous solution in which a ligand such as citric acid to form a chelate complex is dissolved. The hydrophilicity of the hydrophilic surface is restored by applying the hydrophilicity-restoring agent to the hydrophilic surface with a reduced hydrophilicity and removing the hydrophilicity-restoring agent after an appropriate lapse of time.

  • Publication number: 20130223643
    Abstract: Introduction of sounds outside a vehicle is automatically controlled according to a driving state of the vehicle. In a vehicle, a microphone device that collects sounds outside the vehicle and a speaker device that reproduces the collected sounds are installed. When a gear position for the vehicle is a reverse driving position, and until the vehicle reaches a predetermined speed for the first time after a key position in an ignition key switch is switched from an off position to an accessories position or an on position, the collected sounds are reproduced. The collected sounds are transmitted to a car navigation device or a car audio system via wires or wirelessly. When the sounds outside the vehicle are reproduced, sound reproduction in the car navigation device or the car audio system is stopped and the sounds outside the vehicle are reproduced at a set volume.

  • Patent number: 8480273
    Abstract: In an outer mirror with turn lamp having a structure in which a turn lamp assembly is mounted to a mirror housing, then a housing cover is placed over and mounted to the mirror housing, and a lens of the turn lamp assembly is exposed through an opening in the housing cover, misalignment between the lens of the turn lamp assembly and the opening in the housing cover is prevented. A protrusion is formed on a back surface near the innermost part of an opening in a housing cover. A hole is formed in the turn lamp assembly in a position facing the protrusion with the housing cover being placed over the mirror housing. When the housing cover is placed over the mirror housing, the protrusion is inserted into and engaged with the hole. This prevents misalignment between the lens of the turn lamp assembly and the opening in the housing cover.
