    摘要: An optical fiber electric current sensor includes a polarization-splitter (13) that splits light outputted from a sensor fiber (11) into two polarization planes of which polarization directions are perpendicular to each other, a depolarizer (17) that depolarizes each of the polarization components from the polarization-splitter (13), light receiving element that converts the two lights that were depolarized by the depolarizer (17) to a first signal (S1) and a second signal (S2) respectively, and a signal processing unit (15) that, based on the first signal (S1) and the second signal (S2), determines the magnitude of a Faraday rotation applied to the linearly-polarized light, and thereby calculates a value of the current to be measured.

    摘要: An automatic power transmission control system includes a solenoid valve which is associated with an electric or electronic controller to receive therefrom a control signal. The solenoid valve generates a hydraulic control pressure in response to the control signal. The solenoid valve supplies the control pressure to a shift valve for switching shift valve position between a higher gear position and a lower gear position. The solenoid valve is also hydraulically communicated with a hydraulic device which performs desired operations associated with gear position shifting operation. The solenoid valve supplies the control pressure to the hydraulic device for controlling operation of the latter corresponding to the selected gear position.

    摘要: A small sailing watercraft designed to be operated primarily by a single rider standing on the deck and having an improved hull configuration for improved handling in all seas and all wind conditions. The hull is hollow and is formed with a generally narrow displacement hull with a substantially larger deck area closing it so as to accommodate various standing positions for the rider. A pair of sponsons are disposed adjustably at the opposite side of the main hull and are carried by outriggers that are connected to the main hull in an area where it is reinforced by internal bulkheads. The hollow hull also affords a storage compartment.
