摘要： A spark plug having a center electrode that includes a columnar noble metal tip at one end thereof, and a ground electrode that forms a spark gap between the ground electrode and a circular discharge surface of the tip. In the tip, a mass % of Pt is largest and a content percentage of Ni is more than or equal to 0 mass % and less than or equal to 40 mass %. In each of both a cross-section of the noble metal tip parallel to the discharge surface and a cross-section of the tip perpendicular to the discharge surface, particles each having an aspect ratio of more than or equal to 1 and less than or equal to 10 occupy more than or equal to 70% of observed particles in an area extending from an outline of the cross-section by a distance of 10% of a diameter of the discharge surface.

摘要： A gas sensor (100) extending in an axial direction AX including: a gas sensor element (120) which detects the concentration of a specific gas in a gas under measurement; a tubular metallic shell (110) having a polygonal tool engagement portion (110B) surrounding the gas sensor element (120); a tubular outer tube (103) which extends rearward from the metallic shell (110), surrounds the gas sensor element (120), and has an opening (103E) at a rear end thereof; a sealing member (191) which seals the opening (103E); and a tubular heat dissipating member (104) which surrounds the outer tube (103) and reduces the amount of heat transferred from the forward end side of the gas sensor (100) through the outer tube (103) to the sealing member (191). The maximum diameter D1 of the heat dissipating member (104) is equal to or less than the opposite side dimension D2 of the tool engagement portion (110B).

摘要： A semiconductor package includes a substrate body made of an insulating material and having a frame shape with a through hole; and a heat-dissipating member made of a metallic material and having a top face serving as an element-mounting surface, the element-mounting surface being positioned in the through hole. A back face of the substrate body and a front face of the heat-dissipating member are joined to each other with a joining agent, the back face being oriented downward, the front face being oriented upward. The substrate body includes a first riser portion extending downward from the back face. The heat-dissipating member includes a second riser portion extending upward from the front face. The joining agent is placed in a space enclosed by the back face, the first riser portion, the front face, and the second riser portion.

摘要： A spark plug includes a metal shell and a cap member joined to the metal shell to define a pre-chamber. The cap member includes an overlapping surface that overlaps the metal shell along the axial line direction, an inner facing surface positioned closer to the pre-chamber than is the overlapping surface, the inner facing surface facing the metal shell in the axial line direction, and an outer facing surface positioned closer to an outer periphery than is the overlapping surface, the outer facing surface facing the metal shell in the axial line direction. A portion of the cap member that is closer to the pre-chamber than is the overlapping surface s spaced from the metal shell. The metal shell and the cap member are joined together at at least one of the outer facing surface and the overlapping surface.

摘要： A spark plug including a center electrode that has a large-diameter portion having an outside diameter that is largest in the center electrode. The large-diameter portion is retained at a rear facing surface in an axial hole of an insulator. A metal shell has a diameter increased portion on a rear end side with respect to the center electrode, the diameter increased portion having an inside diameter that is increased toward the rear end side. The insulator has a first portion which is a portion of the insulator in a region from a rear end of the rear facing surface to a front end of the diameter increased portion. The first portion has a thickness that is the largest in the region, and is disposed at least on an outer periphery of the large-diameter portion.
