The invention relates to the kinematic connection of a fixed platform to a mobile platform comprising up to six degrees of freedom in closed kinematic chains,, the connecting elements being rods, of adjustable length, optionally consisting partially of rods of a constant length, and optionally cables. A first insulating pattern is on the first polysilicon pattern. As a result, the R1FeB coarse powder exhibits intrinsically excellent magnetic properties, and a bonded magnet with excellent magnetic properties and permanent flux loss ratio is obtained. The overlap joint has a thickness W2 substantially equal to or less than W1 to provide a free-bump transition between the first and second strips while preventing straight-through infiltration.
