An ink jet printer enabling dual-way printing has a head that can create different types of dots having different diameters. When using a machine quilting frame, one balances on one foot while controlling the speed and power of the sewing machine and moving the sewing machine from side to side and to and fro on a carrier. Each of the first set of semiconductor chip package substrates has a first footprint. Because non-cancerous cells do not over-express VGSCs, less sodium and less water will enter the cells, and the non-cancerous cells will not lyse. The first spark gap is radially oriented while the second spark gap is axially oriented, and the first and second spark gaps are located at different axial positions and can fire independently of one another.
