One branch of the bridge circuit comprises a series circuit consisting of a first resistor and a first Josephson junction connected between the first and second input terminals. The second branch comprises a parallel circuit of a second Josephson junction and a second resistor connected between the first input terminal and a grounding terminal of the bridge circuit. The third branch comprises a third resistor connected between the second input terminal and the output terminal. The fourth branch comprises a third junction connected between the output terminal and the grounding terminal. A load resistor is connected between the output terminal and the ground.
摘要:
A combustion chamber for an internal combustion engine of the direct injection type defined by a cylinder head, a cylinder liner and a piston head, the piston head having formed therein a cavity in which air swirl can be produced by a known means.A fuel injection valve having a plurality of fuel injection nozzles is disposed above the cavity for injecting jets of fuel radially against the cavity wall.The cavity comprises an equilateral polygonal cavity formed in the upper part of the piston head and a toroidal cavity formed continuously to the polygonal cavity in the lower part of the piston head. The equilateral polygonal cavity has rounded corners formed therein, the ratio of the radius of the rounded corners to that of a inscribed circle of the equilateral polygonal cavity being from about 0.05 to about 0.8.
摘要:
A polarizing film which comprises a polyvinyl alcohol-based resin film and iodine being adsorbed thereon and oriented, and is prepared, for example, by subjecting the polyvinyl alcohol-based resin film to a dyeing treatment, to a stretching treatment, to a boric acid treatment and further to a complementary color treatment in which the film is immersed in a solution containing a chlorinated compound. The polarizing film is so adjusted as to have a boric acid content of 5 to 40 weight % by the dyeing treatment, stretching treatment and boric acid treatment, and also to have a chlorine ion content of 200 to 10,000 ppm by the complementary color treatment. The above polarizing film retains an achromatic hue when it is arranged at a parallel Nicol position, and also exhibits improved durability of its optical characteristics under a high temperature and high humidity condition, and a high temperature condition.
