摘要： A distributed refractive index type optical transmission plastic article has a circular cross section of a radius r.sub.0 which is in a range of 0.4 to 0.6 mm. A refractive index distribution of the optical transmission article substantially approximates a predetermined ideal refractive index distribution curve at least in a range of 0.25r.sub.0 to 0.70r.sub.0 extending from a center axis toward a peripheral surface of the article. A refractive index n.sub.0 at a central part of the article is in a range of 1.4 to 1.6. The article has a refractive index distribution constant of larger than 0.15 mm.sup.-1 and smaller than 0.3 mm.sup.-1, and a modulation transfer function of at least 55%. This optical transmission article is made from uncured liquid substances each having a viscosity of between 10.sup.3 and 10.sup.8 poises. N (N.gtoreq.2) uncured liquid substances having refractive indexes n of n.sub.1 >n.sub.2 >n.sub.3 . . . n.sub.N when cured are arranged in such a way that the refractive indexes n are successively reduced from a central portion toward a peripheral portion, and concentrically laminated one upon the other to form an uncured strand fiber. The substances between adjacent layers of the fiber are mutually diffused. During the diffusion or thereafter, the uncured strand fiber is cured, thereby completing the production of the optical transmission article.

摘要： A driving force margin of a vehicle is calculated on the basis of an engine load, vehicle speed, travel resistance and estimated uphill gradient. A gear is determined on the basis of predetermined gear shifting characteristics at least from the vehicle speed and the engine load in an automatic shift mode. Automatic down shift is generated in the case where the vehicle speed becomes lower than vehicle speed on an automatic down shift vehicle speed table set up in accordance with the gear when the operation is switched from the automatic shift mode to a manual shift mode. The automatic down shift vehicle speed table is corrected so as to shift an automatic down shift line to a high vehicle speed side or low vehicle speed side in accordance with the magnitude of the calculated driving force margin of the vehicle.

摘要： A control apparatus for an automatic transmission includes an operational condition detecting unit for detecting a vehicle operational condition, a slope detecting unit for detecting a road surface slope, and a shift characteristic selecting unit for selecting one of a plurality of shift maps preliminarily set according to the road surface slope. The control apparatus further includes an acceleration/deceleration calculating unit for calculating an acceleration or deceleration from the degree of increase or decrease in vehicle speed per unit time, a deceleration shift characteristic for deciding a gear position according to the deceleration and the vehicle speed, and a brake detecting unit for detecting a brake operation. When the road surface slope is determined to be a downhill slope and the brake operation is detected, the selected shift map is changed to the deceleration shift characteristic and the gear position is decided according to the deceleration shift characteristic.
