Low head water turbine

A low head water turbine comprising a runner having a cylindrical outer surface and a plurality of similar blades similarly pivotably secured along their inner sides to the outer surface of the runner so as to pivot in the direction of rotation of the runner between a closed position lying adjacent the outer surface of the runner and an open position at an angle thereto. A housing having end walls and a rounded side wall extending therebetween, completely encases the runner and its blades. The runner is eccentrically mounted to end walls of the housing for rotation about a horizontal axis so that the cylindrical outer surface is spaced closer to an upper portion of the housing side wall and farther from a lower portion. A water inlet opening is located in a lower, forward portion of the housing, below the axis of rotation of the runner. A water outlet opening is located in a lower, rearward portion of the housing. During operation of the turbine, the blades will be constricted by the side wall of the housing and thereby moved to the closed position as they approach and pass the upper portion of the housing side wall, and will move to the open position under force of gravity, water and centrifugal force acting on them as they move below the axis of rotation of the runner to the lower position, all the time the housing side wall acting on the outer sides of the blades.

Spark plug

A spark plug is such that a front end portion of an insulating member projects 2 mm or larger from a front end face of a metal shell and a volume of a portion of the insulating member which lies within a range from a front end of the insulating member to a position lying 1 mm towards a rear end side from the front end is 11 mm3 or smaller. When assuming that a corner portion where a front end face of the insulating member intersects a side surface of an axial hole is referred to as a position PA, a position on a center electrode where a straight-line distance from the position PA to the center electrode within the axial hole is referred to as a position PB, a position where the insulating member first contacts the metal shell from the front end face of the insulating element along a surface of the insulating element is referred to as a position PC, and a position on the insulating element where a straight line BC which connects the position PB with the position PC contacts the surface of the insulating member when the straight line BC is displaced parallel towards an outside of an axis is referred to as a position PD, a parallel displacement amount E by which the straight line BC is displaced parallel until it contacts the position PD is 0.75 mm or larger. According to the spark plug configured in this way, even though the spark plug is shaped small, the occurrence of lateral spark and inside spark can be suppressed effectively.
