Abstract: A spark plug includes a ceramic insulator, and the insulator includes a melted portion formed by melting a surface of a base material. In a cross section of the insulator, the value obtained by dividing a length of an interface between the base material and the melted portion by the length of a line segment connecting two ends of the interface is 1.1 or more and 1.5 or less.

Abstract: A spark plug including an insulator and a metallic member such as a metallic shell. In the spark plug, a mark such as a two-dimensional code is provided on the surface of at least one of the insulator and the metallic member. Also, a protective layer covers the mark. The protective layer is optically transparent and contains a fluorescent substance.

Abstract: A spark plug includes a tip extending in a first direction and an electrode base metal having an extending portion extending in the first direction and connected to the tip through a fusion zone. In a section taken along the first direction and containing a center axis of the tip, in a case where two ends of the interface between the extending portion and the fusion zone are located at the same position with respect to the first direction, the linear distance between the ends is denoted by A, or, in a case where one end is located forward of the other end, the distance from the one end to an intersection between a straight line passing the one end and extending perpendicularly to the center axis and the outline of the fusion zone is denoted by A. The interface length B satisfies a relational expression B/A?1.2.

Abstract: A container of a liquid applicator containing a liquid, and an applicator member is held on the container for applying the liquid to an objective part. The applicator member is mounted for movement into and out of the container and a biasing member is provided to bias the applicator member outwardly of the container. When the applicator member is pressed into the container against the force of the biasing member, the liquid is caused to exude to the surface of the applicator member outside the container. Therefore, it is possible to provide a liquid applicator which has a container of any desired volume and made of a rigid and hard material and which allows only the liquid to exude to the outer surface of the container and be spread properly and effectively over an objective part.

Abstract: The present invention is concerned with a monoclonal antibody capable of preferentially recognizing arteriosclerotic lesions and prepared from a hybridoma obtained by fusing myeloma cells and cells capable of producing antibodies against arteriosclerotic lesions, such as spleen cells, peripheral lymphocyte of thymus and peripheral vascular cells, the antibody can be to use as an agent for detecting the presence of arteriosclerotic lesions and for treating arteriosclerosis.

Abstract: In a water-cooling system for a water-cooled horizontal cylinder engine, a radiator and a radiator fan are arranged at the front of a cylinder head which is mounted forwardly of a cylinder block of the engine. A radiator fan generates a cooling air flow which passes through the space over the cylinder head and toward the radiator, the height of the radiator being sized to match the width of the cylinder block measured in the upward and downward direction.
