A liquid container mountable in a liquid ejecting apparatus. Moreover, an optical integrated device includes at least a semiconductor laser and an optical waveguide device both mounted on a submount, wherein the semiconductor laser is the wavelength-variable semiconductor laser as set forth above. A first insulation layer surrounds the information-conducting core and has a dielectric strength. In this regard, the generated keys may be written to one or more of the key registers only by the key controller block. A signal primitive having one or more information elements indicative of corresponding power offsets are received by the Node B, saved for future use and then signalled back to the serving radio network controller so that the user equipment can be informed with a proper RRC message containing the appropriate power offsets.
