Disclosed is a shift power transmission apparatus for readily suppressing or avoiding size increase thereof. The apparatus includes an input shaft () receiving engine drive force, a hydraulic continuously variable transmission () driven by the input shaft (), a planetary power transmission section () combining drive force from the input shaft () and output from the hydraulic continuously variable transmission () for outputting the combined drive force, and an output rotary member () outputting power to a travel apparatus. The planetary power transmission section () and the output rotary member () are arranged on a side of the hydraulic continuously variable transmission () associated with an engine-coupled side of the input shaft (). The drive force is inputted to the planetary power transmission section () from a portion between the engine-coupled side and the hydraulic continuously variable transmission-coupled side of the input shaft ().

A phase-modulated fiber optic gyroscope comprises a signal generating a signal generating section, a photoelectric converter section and a signal processing section. The signal generating section includes a light source, an optical path for propagating light from the light source clockwise and counterclockwise, and a phase modulator for modulating the light propagating through the optical path. The photoelectric converter section converts an optical signal received from the signal generating section into an electric signal. The signal processing section derives a direction of rotation and a velocity of rotation from the electric signal received from the photoelectric converter section. The signal processing section includes an analog-to-digital converter for converting the electric signal received from the photoelectric converter section into a digital signal, and a digital signal processor for carrying out angle calculations based on the digital signal received from the analog-to-digital converter.
