A method and apparatus for a driver layout is described. A layout without the share ports for each of the chips based on the design files for each of the chips is generated and a layout versus schematic check is conducted for each of the generated layouts by using the identified inter-layer ports. The second fitting element includes a second envelope and a second sole of the strobel type, the second envelope being fixed to the second strobel sole at least with stitching. The slot machine determines whether a propagation criteria has been achieved and outputs a propagation signal, indicating a performance adjustment, to at least one other slot machine. The housing accommodates the sensor coil therein. The protecting layer contains a silicone resin particle having at least one structural unit represented by RSiO1.
