Disclosed are a method for rapid screening suitable translational fusion partners capable of inducing expression or secretory production of non-producible proteins, which are difficult to produce in conventional recombinant production methods, from a variety of genetic sources, and protein secretion-inducing TFPs obtained using the method. One or more of the data values are displayed as contours around one or more data points and each data value is centred on a data point. The liquid crystal projector has an outside size in a horizontal plane of 263 mm by 318 mm or below. A projection member is disposed on a surface of the edge opposing the optical disk and on a side of the gap opposing the optical disk.
