Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To effect high-precise diagnosis of abnormality of a fuel feed system of an engine not only during stoickly operation but also during lean operation. SOLUTION: A target engine torque change ΔRTe is computed and meanwhile, from a signal from a crank angle sensor 2, the angular acceleration speed change of a crank shaft is determined and the actual generating change Δtorque of an engine is estimated and computed. Further, Δtorque is compared with ΔRTe.

Title: Luminaire having air-cleaning function
Inventor: TOMIBAYASHI KAZUYUKI
IPC: B01D46/00
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a luminaire having air-cleaning function which can suck smoke from the entire space ranging from a region directly under a suction part to a peripheral edge part of a shade, without losing smoke and does not release cigarette smoke and/or bad smell to the surrounding even if a filter becomes dirty and its purification ability drops. SOLUTION: In this luminaire, an emission of air 10 from an air cleaner 2 to the bottom edge of a shade 32 raises an air flow along a slant face of the shade 32, an air flow permitting suction from the space ranging from a peripheral edge part of the shade to an area directly under the center of the shade. The circulation of the air inside the luminaire with no emission to surroundings prevents cigarette smoke and/or bad smell from being released, even when a filter becomes dirty and its purification ability drops. As means for circulating air, the shade of the luminaire 1 employs a double shade 3, so that the air exhausted from the air cleaner can be discharged from a space close to the bottom edge of the shade.
