An image forming apparatus operates in modes including a normal mode and a power saving mode less in power consumption than the normal mode. Tags include a processor to determine a backscatter link period result by dividing a count value representing the calibration symbol by the divide ratio and adding an adjustment. In addition, an un-doped silicon layer is formed over the first and second regions, and a first and a second fin structures are formed. An elongated handle has one end secured to the other end of the arm by a locking joint which selectively locks the handle to the arm at a plurality of predetermined angular positions. The new cultivar can perfectly be used in 10-12 cm pots and grown without growth regulators. Thus, the present invention provides for a method and a HSS to allow the implicit registration of more than one IMPI, or the implicit registration of more than one contact address, or both, upon explicit registration of a subscriber with a given IMPIIMPU pair and a given contact address.
