A method and apparatus for blow molding a case for housing an object, such as a tool, is disclosed generally comprising first and second mold portions located adjacent each other to create separate cavities for forming base and lid portions of a case and a punch for each portion corresponding to the outline of an object. Alignment of liquid crystal molecules of the liquid crystal layer is controlled by an electric field generated between the common electrode and the pixel electrode. The terminal receives the SIB including the updated access barring information immediately without waiting for the arrival of next modification period, resulting in improvement of access barring efficiency. Vref can be made to vary across its allowable range during AC self test to provide improved coverage. A central trunk coupled to the clock port and located between a first pair of circuit pathways with paired branches that extend from the trunk and that couple to the data conversion circuits make up the clock distribution circuit.
