Patent number: 10042090Abstract: In a hydrophilic member including a structure in which a photocatalytic TiO2 layer and a porous SiO2 layer are stacked on a surface of a base material, easy forming of the porous SiO2 layer so as to be thin and have a uniform film thickness distribution that enables the porous SiO2 layer to cover an entire surface of the photocatalytic TiO2 layer, and enhancement in durability of the porous SiO2 layer are enabled. A photocatalytic TiO2 layer is formed so as to have a density of 3.33 to 3.75 g/cm3 (preferably 3.47 to 3.72 g/cm3, more preferably 3.54 to 3.68 g/cm3) on a surface of a base material. As an outermost surface layer, a porous SiO2 layer is formed on the photocatalytic TiO2 layer in such a manner that the porous SiO2 layer has a film thickness of no less than 10 nm and no more than 50 nm.Type: GrantFiled: October 28, 2013Date of Patent: August 7, 2018Assignee: MURAKAMI CORPORATIONInventors: Masatoshi Nakamura, Syungo Ikeno, Shinya Takayanagi

Patent number: 8599037Abstract: 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.Type: GrantFiled: January 17, 2012Date of Patent: December 3, 2013Assignee: Murakami CorporationInventor: Shinya Takayanagi

Patent number: 8308325Abstract: The present invention is intended to provide an image pickup device-equipped rear view mirror with improved image pickup performance, glare prevention and appearance (design) in addition to improved performance as a vehicle mirror. A mirror element is formed by forming a reflecting film consisting of high refractive index material films and a low refractive index material film on a back surface of a transparent glass substrate. The integrating sphere reflectance of the mirror element in the visible range is 40% to 60% and the near-infrared transmittance is no less than 70% for the whole or part of the band belonging to the near-infrared range within the entire sensitive wavelength range of the near-infrared camera. A black mask member is attached to an entire back surface of the reflecting film. The near-infrared camera is arranged behind the black mask member.Type: GrantFiled: April 30, 2008Date of Patent: November 13, 2012Assignee: Murakami CorporationInventors: Shinya Takayanagi, Masatoshi Nakamura

Publication number: 20120230045Abstract: An aspect of the present invention provides a rearview mirror designed to enhance assembly workability. When assembling a mirror unit of the rearview mirror, a lamp unit is dropped in an opening provided on a mirror holder from an inner surface side of the mirror holder in a condition in which side object detection symbols face upward. Thereafter, a circumferential edge of a reflective mirror is fitted into a recess-shaped fit portion of the mirror holder. The lamp unit is thus simply clamped and fixed between a lamp unit receiving portion (tab portions) and the reflective mirror. When the lamp unit is assembled in the mirror unit, therefore, adhesive is not used, so that workability is extremely good.Type: ApplicationFiled: January 17, 2012Publication date: September 13, 2012Applicant: MURAKAMI CORPORATIONInventor: Shinya TAKAYANAGI

Patent number: 8169307Abstract: To provide a vehicle rear-view mirror equipped with a display device, configured so that: a warning indication is easy to see from the driver and is hard to see from following vehicles and vehicles on the adjacent lanes; and when no warning is indicated, no discontinuities occur in the rear-area image reflected in the mirror and the warning symbol is unnoticeable. A mirror element 18 is configured by forming a semi-transmissive reflective film 24 or 56 formed of a dielectric multilayer film on the back or front surface of a transparent glass substrate 22. A dark color mask member 26 is arranged on the back surface of the mirror element 18. An opening 26a is formed on the mask member 26. A light-orienting tube 28 is arranged in such a manner that it protrudes in the backward direction of the mask member 26 so as to surround the opening 26a. The tube axis 28a of the light-orienting tube 28 is inclined in the direction toward the driver's viewpoint.Type: GrantFiled: June 13, 2008Date of Patent: May 1, 2012Assignee: Murakami CorporationInventors: Masatoshi Nakamura, Shinya Takayanagi, Atsunori Bandou, Yoshifumi Masuda

Patent number: 8004768Abstract: The present invention provides a vehicle mirror and a manufacturing method therefor which allow the rear face side of a mirror element to be dark-colored without using a color plate or color coating. A mirror element is configured by forming a semitransparent reflective film made of a dielectric multilayer film on the front face of a flat transparent substrate. A dark-colored self-adhesive film is attached to the rear face of the mirror element. The dark-colored self-adhesive film is configured by forming an adhesive layer on the rear face of a dark-colored film layer by means of application. Grid-like air release channels are formed at fine pitches with minimal depth on an entire surface of the adhesive layer. After the dark-colored self-adhesive film is attached to the rear face of the mirror element, the grid-like air release channels visible from a front side of the mirror element are eliminated by heating and/or pressurizing.Type: GrantFiled: December 30, 2009Date of Patent: August 23, 2011Assignee: Murakami CorporationInventors: Shinya Takayanagi, Masatoshi Nakamura

Patent number: 7980711Abstract: Interference of light is prevented from occurring in a rear-view mirror incorporating a light-emitting display device where a dark color mask member is arranged behind a mirror element. A mirror element is formed by forming a semi-transmissive reflective film on one surface of a transparent substrate. On a back surface of the mirror element, a dark color mask member is arranged. An opening a is formed in the dark color mask member Behind the mirror element, a light-emitting display device is arranged facing the opening. A protrusion forming a spacer is formed on the entire peripheral edge of a front surface of the dark color mask member. The spacer provides a clearance gap between the semi-transmissive reflective film and the dark color mask member.Type: GrantFiled: January 30, 2009Date of Patent: July 19, 2011Assignee: Murakami CorporationInventors: Shinya Takayanagi, Masatoshi Nakamura

Patent number: 7695174Abstract: Visibility of indications in a rear-view mirror incorporating a light-emitting display device is improved. A mirror element is formed by forming a semi-transmissive reflective film on one surface of a transparent substrate. On a back surface of the mirror element, a dark color mask member is arranged. An opening is formed in the mask member. Behind the mirror element, a light-emitting display device is arranged facing the opening. Where the mirror element is formed of a plane mirror, the light-emitting display device is arranged in such a manner that it is inclined toward a driver relative to the mirror surface. A wedge-shaped gap occurring between the mirror element and the light-emitting display device due to the inclination is occluded by a wall member.Type: GrantFiled: August 20, 2008Date of Patent: April 13, 2010Assignee: Murakami CorporationInventors: Shinya Takayanagi, Masatoshi Nakamura, Masahiro Motomiya
