Abstract: A negative electrode material for a secondary battery includes a matrix containing silicon oxide, a composite oxide of one or more doping elements selected from an alkali metal, an alkaline earth metal, and a post-transition metal, and silicon, or a mixture thereof; and silicon nanoparticles dispersed and embedded in the matrix.

Abstract: A multiple radio data service antenna module integrated in a rear view mirror being exposed towards a windscreen in an activated state enhances quality of reception of multiple radio data services and a display unit being integrated in a rear view mirror surface displaying information received by said antenna module informs a driver about relevant data of said data service without distracting the driver.

Abstract: A vehicle inside mirror device for displaying an image, which can obtain an enhanced mirror function of a prismatic glass caused by a black film provided at a rear side of a prismatic glass and has a relatively simple structure made by forming directly a transflective layer on a rear surface of a prismatic glass without using a substrate. The vehicle inside mirror device comprises a housing mounted in a passenger compartment of a vehicle; a prismatic glass provided on a front side of the housing and having a transparent transflective layer formed on a rear surface thereof; a black film provided at a rear side of the prismatic glass and having an opening formed on one side thereof; a liquid crystal display (LCD) module provided at a rear side of the opening of the black film; and a control circuit unit installed at a rear side of the LCD module.

Abstract: A vehicle inside mirror device employs a ball clamp in which a barrel-shaped ball clamp is prepared by assembling a pair of semi-barrel-shaped and symmetrical bodies to accommodate for manufacturing errors and the like. The ball clamp includes a mirror through which a driver can view rearwardly; and a mirror mounting part. The mirror mounting part has a barrel-shaped hinge part. A first ball clamp surrounds and clamps the hinge part. A second ball clamp corresponds to the first ball clamp with a spring between the first ball clamp and the second ball clamp for generating an expansion force. The mirror mounting part is fixed to a glass or a ceiling of a vehicle and has a hinge part for coupling the second ball clamp thereto. A tube surrounding the first ball clamp, the second ball clamp and the spring.

Abstract: The present invention is related to a vehicle inside mirror device employing ball clamp in which a barrel-shaped ball clamp is prepared by assembling a pair of semi-barrel-shaped and symmetrical bodies to absorb a mechanical error or an assembling error caused by a loosen assembly between the ball clamp and a counterpart or caused by a press-fitting manner for inhibiting a deformation of the ball clamp.
