Title: Multi-layer flexible drive sprocket
Inventor: OERTLEY THOMAS E
IPC: B62D55/096
Filed: 2001-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a drive sprocket assembly driving an endless chain assembly propelling a vehicle with multi-layer flexible teeth for separately deflecting each layer at a collision by a bush of the endless chain assembly. SOLUTION: Since individual flexibilities of each tooth in a multi-layer structure are smaller than flexibility in a single wide integral tooth and because of expected variation in contour and web shape of teeth due to allowable manufacturing error, a collision of the crawler bush does not occur at the same time. First, the crawler bush meshes with one or more tooth of a multi-layer teeth structure. As a result, the tooth receiving the collision first absorbs at least a part of the kinetic energy before the bush collides with the remaining teeth in the multi-layer structure.

Abstract: PROBLEM TO BE SOLVED: To provide an MRAM capable of storing lager amount of data in a single memory cell. SOLUTION: In the MRAM, tunnel insulating layers (5-1 through 5-3), are provided so as to be sandwiched between first to (n+1)-th magnetic material layers (4 and 6-1 through 6-3) and an i-th magnetic material layer, which have spontaneous magnetization respectively. Here, an i-th junction resistance between the i-th magnetic material layer and an (i+1)-th magnetic layer is set to Ri , where the i-th spontaneous magnetization has the same direction as that of the (i+1)-th spontaneous magnetization, and the i-th junction resistance is set to Ri +ΔRi , where the i-th spontaneous magnetization has the different direction from that of the (i+1)-th spontaneous magnetization. In this case, it is decided that ΔRi , ΔR2 through ΔRn have different values.  In the MRAM with this constitution, the resistant value between the first magnetic material layer and the (n+1)-th magnetic material layer can be different values of  (n<2> +n+2)/2} pieces or more, according to the direction of the first-(n+1)-th spontaneous magnetization.
