Abstract: A range control system includes an input section for inputting a singing voice, a fundamental frequency extracting section for extracting a fundamental frequency of the inputted voice, and a pitch control section for performing a pitch control of the inputted voice so as to match the extracted fundamental frequency with a given frequency. The system further includes a formant extracting section for extracting a formant of the inputted voice, and a formant filter section for performing a filter operation relative to the pitch-controlled voice so that the pitch-controlled voice has a characteristic of the extracted formant. The system further includes an input loudness detecting section for detecting a first loudness of the inputted voice, and a loudness control section for controlling a second loudness of the voice subjected to the filter operation to match with the first loudness.

Abstract: In a mounting structure for a relay arranged on a printed circuit board, a resin block having at least one insert-molded bus bar is fixed on the printed circuit board. One end of the bus bar held by the resin block is joined together with a terminal of the relay by welding, while the other end of the bus bar is soldered to a printed wiring pattern formed on the printed circuit board. Therefore, a heat (temperature) of the terminal of the relay can be absorbed through the bus bar and the resin block.

Abstract: An operating speed change-over device is equipped with an automatic speed change-over valve which opens and closes a pilot fluid line that connects a pilot port of a capacity change-over valve of a capacity-variable hydraulic motor to a pilot pump. The automatic speed change-over valve has one pilot port that is connected to a pressurized fluid feed line leading to the hydraulic motor and has another pilot port connected to the return fluid line of the hydraulic motor. The automatic speed change-over valve is changed over by an effective differential pressure between the two fluid lines.

Abstract: A fluorescence determining microscope scans the surface of a specimen with laser light. The fluorescence produced is split into components of different wavelengths, and the fluorescence of the respective wavelengths is determined.
