Pharmaceutical formulations are provided which are in the form of capsules or tablets for oral use and which include a medicament dapagliflozin or its propylene glycol hydrateand a pharmaceutical acceptable carrier therefor, which formulation is designed for immediate release. The preferably stands for an unsubstituted or substituted fused hydrocarbon ring system selected from naphthalene, antracene, phenanthrene, and pentacene. A method for fabricating the optical chip according to the present invention can enhance an optical chip yield rate, and further, can fabricate an optical chip having the shape for stabilizing optical characteristics of the arrayed waveguide grating type optical multiplexerdemultiplexer circuit. During a calibration mode, the RF input signal is disabled, and the first LO signal is injected into the filter input by leaking the first LO signal through the mixer circuit. When the instruction is received, the apparatus moves the focusing lens based on the focus signal of the identified object region to be focused to detect a focus signal and perform a focus adjustment for the focusing lens.
