The present invention provides a method of forming an image on a printing plate, in which a nanopaste is imagewise ink-jet applied onto a surface of a substrate. MRAM cells are formed at intersections of the word lines and the bit lines therebetween. The controller circuit may be configured to cause the sample and hold circuit to sample the value of a derived signal that is derived from a connection to the primary winding at a time when the primary winding is decoupled from the energy-supplying circuit and the diode is conducting current, and to hold the sampled value at least until the diode stops conducting current. , and can be focused using antenna beams to achieve a simple form of location encryption. The sliding device includes a cleaning material contacting the display panel. With this, it becomes possible to discriminate the four-stroke operating cycle of the general-purpose engine without using an expensive pressure sensor.
