Abstract: Provided is a pneumatic tire which is capable of securing a driving stability on dry road surfaces and concurrently of improving snow performance without worsening its pattern noise. The pneumatic tire includes four main grooves each extending in its tread part in a tire circumferential direction, and the four main grooves partition the tread part into: a center land part; paired intermediate land parts located with the center land part being interposed in between; and paired shoulder land parts located with the center land part and the paired intermediate land parts being interposed in between. Each of the intermediate land parts and the shoulder land parts includes multiple V-shaped grooves each configured of: a thick groove part extending in a tire width direction; and a thin groove part extending in the tire circumferential direction. The V-shaped grooves are arranged in a way that each paired V-shaped grooves are opposed to each other in the tire circumferential direction with a connecting groove part being interposed between vertices of the respective paired V-shaped grooves. Each thick groove part communicates with the main grooves or the outside of a ground contacting area. Each thin groove part terminates within the land part.

Abstract: A nitric acid solution containing ions of any one element selected from the group consisting of rare element FP of Ru, Rh and Pd and a rare element of Re is electrolytically reduced by electrolyzing at a constant current to thereby deposit the ions of the element on an electrode. Alternatively, a nitric acid solution containing ions of two or more elements selected from the group consisting of rare element FP of Ru, Rh and Pd and a rare element of Re is electrolytically reduced by electrolyzing at a constant current to thereby collectively deposit the ions of the elements on an electrode. Alkaline water is electrolyzed by using the thus obtained electrodeposit electrode directly as it is as a catalytic electrode to efficiently generate hydrogen. Thus, a clean and sustaining energy system integrating the nuclear energy with the fuel cell power generation is provided.

Abstract: A molten polyester sheet is solidified by cooling it on the surface of a mobile cooling medium on which a water film has been formed. The sheet is stretched at least 4.5-fold in overall stretching ratio in a longitudinal direction through a plurality of stretching steps. Since casting is conducted via the water film, water is absorbed in the surface layer and the interior of the cast sheet, thus facilitating orientation by stretching in the longitudinal direction and lowering the stretching temperature. As a result, stretching with a high stretching ratio can be attained by multi-stage stretching without conducting high-temperature stretching. Thus, this process can accelerate film formation, improve productivity, and provide a film having reduced unevenness in thickness, less surface roughness and excellent abrasion resistance.
