    摘要: For example, a regulator valve may be controlled from the outside through a positioner, or may be controlled autonomously by an adjusting mechanism in the valve. The result of the control is a change in the dislocation of the valve stem (movable portion). Additionally, there will be a change in a process change magnitude, such as the magnitude of flow of a fluid that passes through the regulator valve, in accordance with the magnitude of dislocation of the valve stem. In this way, the diagnosing operation controlling portion controls the operation of the diagnosing portion based on the magnitude of dislocation of the valve stem or on the magnitude of change of the measurement results (the measurement value) of a process change magnitude.

    摘要: To avoid the phenomenon of unsightly flickering in images projected by the projector, in high pressure discharge lamps—especially in high intensity discharge lamps, such as high pressure mercury lamps, metal halide lamps, and xenon lamps—that are used in projectors, even in the presence of the phenomenon of cyclical modulation of the lamp voltage by the returning the light spectrum when the light reflected by the dynamic color filter returns back through the optical system to the lamp, at least during steady operation of the discharge lamp (Ld), a target lamp current signal generation circuit (Up) acquires multiple lamp voltage detection signal (Sv) over a period that is at least as long as the color order cycle of the dynamic color filter (Of) and generates a target lamp current signal (St) based on the multiple lamp voltage detection signals (Sv) that were acquired.

    摘要: In a power feeding apparatus, current flowing through the discharge lamp is controlled not to exceed a current limit value. Until the discharge status changes to the arc discharge, the current limit value is a first current limit value, and after that, the current limit value changes to the second current limit value. The first current limit value is 70% of the second current limit value or less, and further, for 0.2 ms or greater, the first current limit value is maintained after the discharge status changes to the arc discharge.
