Abstract: A linear array of red LEDs 10R is provided so as to extend in a direction substantially perpendicular to a direction in which a swing-type display device is swung, and a linear array of green LEDs 10G is further provided, the red LEDs 10R and green LEDs 10G being arranged in pairs of two. A CPU activates each of the red LEDs 10R and green LEDs 10G for a predetermined period to emit light in a luminance level in accordance with image data. As a result, an image corresponding to the image data is displayed in the trajectory of the swing due to persistence of vision. Thus, an image can be displayed in various colors.

Abstract: An excitation controller controls excitation of a synchronous machine, which is connected to a power transmission system through a transformer, so that a high-side voltage of the transformer is maintained at a target voltage with high accuracy. An output terminal target voltage of the synchronous machine is set to precisely compensate for a voltage drop in the transformer, corresponding to the transformer phase angle variation. To achieve this result, the excitation controller detects an output terminal voltage and an output current of the synchronous machine and calculates active and reactive currents of the output current, sets the output terminal target voltage of the synchronous machine from the active and reactive currents, the high-side voltage of the transformer, and the reactance of the transformer, and controls excitation of the synchronous machine to compensate for the voltage drop in the transformer corresponding to phase angle variation of the transformer.

Abstract: The invention prevents execution of unauthorized copies of programs. In one example embodiment, a semiconductor storage device includes a program ROM. A calculator of an address processing unit included in the program ROM processes lower bits (e.g., A0-A7) of a first address from an address bus of a CPU using an address calculation code e.g., (a0-a7) from a code storing unit. The calculator outputs a modified lower address (e.g., A0′-A7′). A selector may selectively replace the original lower address (e.g., A0-A7) with the modified lower address (e.g., A0′-A7′) As a result of the replacement, a second address is output from the address processing unit different from the first address.
