A storage capacitor structure comprising a first capacitor electrode on a substrate, a capacitor dielectric layer on the first capacitor electrode and a second capacitor electrode on the capacitor dielectric layer, a passivation layer on the second capacitor electrode and a pixel electrode layer on the passivation layer. Objects in which a distance in the vertical direction of a document is equal to a threshold value or less are included in one object group and the objects in the object group G are grouped as one group. The generated security key is encrypted in a predetermined encryption scheme. The stator core has, for each of the phase windings of the stator coil, n circumferentially-consecutive single-phase slots, in which only the phase winding is received, per magnetic pole of the rotor, where n is a natural number not less than 2. Embodiments described herein may provide efficient processes for providing catalysts in large quantities and using simplified methods. Network traffic associated with the virtual machine is intercepted and redirected to the virtual service node.
