An improvement in the door of a household electrical appliance which comprises a bipartite rotary door containing an outer door, an intermediary door disposed behind the outer door, and an inner rotary door. The substrate has an offset portion, present on the main surface within a range of 92. The system repeatedly 1) enables the user to select a spatial specification defined relative to the currently selected font in the space; 2) determines which fonts, if any, match the spatial specification; 3) displays character-font shapes of those fonts; and 4) makes one of the displayed fonts a new currently selected font relative to which a new spatial specification can be selected. A test signal is firstly issued from the core logic circuit to the gain-adjustable output buffer, while the test signal is then manipulated and outputted to an external device via the inputoutput pin. The invention also provides pharmaceutically acceptable compositions comprising compounds of formula I and methods of using the compositions in the treatment of proliferative disorders. When the switching unit switches the mode to the reproduction mode, the reproduction control unit changes an operation that can be instructed in the reproduction mode according to the selected shooting mode.
