Abstract: The present invention provides a technology of switching the appearance of a product. A decorative film according to an embodiment of the present invention includes: a light control layer including a first transparent conductive film, a polymer dispersed liquid crystal layer containing a polymer matrix and droplets dispersed in the polymer matrix, the droplets each containing a liquid crystal compound and a dichroic dye, and a second transparent conductive film in the stated order from a viewer side thereof; and a reflective layer arranged on a side of the light control layer opposite to the viewer side.

Abstract: The invention is featured in that the natural language process can be made in a way that a chained functions structure expressing relationships among concepts of elements of the natural language constructing the character strings is generated, a rule table which stores in advance rules of association relationship between the chained functions structure and form of a command language which the processor system can execute is looked up, the generated chained functions structure is converted to a form which the process can be executed, and the command language are obtained as results of the analysis by incorporating the information as to the operating statuses of the processor system into the converted form. The invention enables the computer to operate in a desired mode with input of usual natural language without use of any of the formal languages usually given to the computer (special languages and command defined for the computer).

Abstract: In a data processing system having a display, a position indication on a screen of the display, an input unit for inputting data including characters and symbols, and a unit to execute processing in which the execution modes are configured in a hierarchic structure, a mode hierarchic figure is displayed on the screen of the display, the indication position of the operator in the mode hierarchy figure is detected, a destination mode is calculated from the detected information and data representing correspondences between the mode names and positions on the screen, and a mode change is achieved, thereby facilitating the mode transition between modes configured in a complex multilevel hierarchic structure.
