A production method of a positive electrode active material having a LiVPO | 03-21-2013 |
20150057893 | Collision Detection Apparatus and Collision Detection Method - A collision detection apparatus includes: an energy absorption member that possesses conductivity and absorbs impact energy by being crushed in a front-rear direction; two contact members that possess conductivity and are respectively disposed in contact with front and rear end surfaces of the energy absorption member in order to press and crush the energy absorption member in the front-rear direction; a electric resistance detector that is electrically connected to both of the two contact members in order to detect variation in an electric resistance value accompanying crushing of the energy absorption member; and a displacement calculator that calculates a displacement amount of the energy absorption member in the front-rear direction on the basis of the variation in the electric resistance value detected by the electric resistance detector. | 02-26-2015 |
20150069773 | IMPACT ABSORBER - An impact absorber includes a an energy absorbing member that is formed of a composite material and absorbs impact energy by being crushed in a predetermined crush direction, an outer tube member disposed so as to surround the periphery of the energy absorbing member over the energy absorbing member along the crush direction, and a pressing member disposed so as to be in contact with the front end of the energy absorbing member and the front end of the outer tube member and presses the energy absorbing member and the outer tube member simultaneously in the crush direction to thereby crush them. The outer tube member is formed in a shape in which tubular portions are coupled in the crush direction, and is crushed in the crush direction while the tubular portions are regularly folded when the outer tube member is pressed by the pressing member in the crush direction. | 03-12-2015 |
20150069774 | IMPACT ABSORBER - An impact absorber includes a energy absorbing member that is formed of a composite material obtained by reinforcing a resin with a fiber and absorbs impact energy by being crushed in a predetermined crush direction, and a pressing member that is disposed on the front side of the energy absorbing member and presses it in the crush direction to thereby crush the energy absorbing member. The energy absorbing member is configured by stacking, along a radial direction orthogonal to the crush direction, fiber layers having different elastic moduli to a load along the crush direction, and the front end portion of the energy absorbing member is inclined relative to a pressing surface of the pressing member such that the fiber layers are gradually brought into contact with the pressing member sequentially in ascending order of the elastic modulus as the energy absorbing member is pressed by the pressing member. | 03-12-2015 |
