    摘要: A direct injection type diesel engine including a piston having a toroidal combustion chamber wherein the ratio of the diameter of the opening of the combustion chamber to the diameter of the piston, the ratio of the diameter of the opening of the combustion chamber to the depth of the combustion chamber, the ratio of the distance between the top of a toroid of the combustion chamber and the surface of the opening of the combustion chamber to the depth of the combustion chamber and the angle of inclination of a peripheral wall of the combustion chamber with respect to the axis of the piston are each in a predetermined range of values. By these features, the problems with regard to noise and coloring of the exhaust emissions can be obviated without adversely affecting the performance of the engine.

    摘要: A method of elongating a glass body is provided, in which method the axial variation in the inner refractive index structure of a glass body can be restrained. The method comprises: (1) heating and softening a glass body with a heating source that moves in the longitudinal direction while both ends of the glass body are held directly or indirectly by a first holder and a second holder, the first and second holders being distanced from each other; (2) obtaining a first outer-diameter measured value by measuring, with a first diameter monitor, the outer diameter of the core portion lying in the range where the outer diameter of the core portion is decreasing as a result of softening of the glass body; (3) determining the distancing speed of the first and second holders and/or the moving speed of the heating source according to the first outer diameter measured value so that the post-elongation outer diameter of the core portion may become a desired value; (4) and moving the first holder or the second holder and/or moving the heating source so as to elongate the glass body according to the speed thus determined.

    摘要: An acceleration orbit face of particle beam circular acceleration unit is placed at right angles to a rotation shaft of rotation unit for rotating the particle beam circular acceleration unit, beam transport unit, and irradiation field formation unit in one piece. Shields for shielding radiations and magnetism are placed symmetrically with respect to the center axis of the particle beam circular acceleration unit. Shields are placed symmetrically with respect to the center line of the particle beam circular acceleration means, thereby lessening the amount of beams coming in collision with surrounding walls from the beam acceleration orbit, decreasing the radiation leakage amount, lightening the shields, and providing a light particle beam irradiation apparatus.
