Abstract: A time difference measuring device can accurately measure a time difference between two pulse signals generated with a predetermined time difference by measuring the two pulse signals by one measurement. The time difference measuring device measures a time difference between a start signal (M1) and a stop signal (M2). The device has a reference signal generation unit (41) for generating two reference signals (S1, S2) having a ?/2 phase difference. According to corresponding amplitude values (A11, A12) and (A21, A22) of the reference signals (S1, S2) at each generation timing of the start signal (M1) and the stop signal (M2), a phase difference detection unit (42) calculates a phase difference ?? (=?stop??start) between the generation timings of the pulse signals (M1, M2). According to the detected phase difference ?? and the cycle (Ts) of the reference signals (S1; S2), a time difference calculation unit (44) calculates the generation time difference ?t between the pulse signals (m1, M2).

Abstract: A method for estimating the sulfur content in the fuel of an internal combustion engine equipped with a catalyser, using a current sulfur concentration value (Sold) and a correction of said current sulfur concentration value (Sold) in order to obtain a new sulfur concentration value (Snew). The method includes the steps of measuring a first time interval (t1-t0) which is actually necessary in order to complete a regeneration process to remove sulfur; determining a quantity (SOxstored) of sulfur stored in the catalyser before the regeneration process to remove sulfur using the current sulfur concentration value (Sold); estimating a second time interval (t2-t0) which is theoretically necessary to complete the regeneration process, on the basis of the estimated quantity (SOxstored) of sulfur stored in the catalyser; and determining a multiplicative correction coefficient as a ratio between the first time interval (t1-t0) and the second time interval (t2-t0).

Abstract: An illuminating optical device comprises a light source for supplying light, and a condenser lens system for collecting the light from the light source and guiding the light onto an object to be illuminated. The condenser lens system has an optical element that has a refractive power, and that can be tilted or decentered with respect to the optical axis of the condenser lens system. By tilting or decentering the optical element, sloped illuminance distributions can be deliberately produced, which can cancel out uneven illuminance distributions having opposite slopes which originally exist in the system. Consequently, satisfactory uniform as well as desired specific non-uniform illuminance distributions can be achieved.
