A controlling method of logic operations is used to control a plurality of logics inside a chip, which is in a power peak state. Such electrographic printing includes the steps of forming a desired print image, electrographically, on a receiver member utilizing predetermined sized marking particles; and, where desired, forming one or more final multi-channeled layers utilizing marking particles of a predetermined size or size distribution. By rigidly positioning the coupling mechanism between the A-arm and the torsion bar so that the distance of the point of attachment from the A-arm’s pivot point in the frame remains substantially the same, the torsional effect of the torsion bar is retained without material change. The microchip allows the user to select specific functions based on the time duration of activation signals, the time duration between activation signals and the number of activation signals at the input. The substrate portion has upper and lower wiring patterns on its top and bottom surfaces, respectively. The injector andor the supply line to the injector form a local pressure reservoir chamber.
