摘要： A tip is welded appropriately using an energy beam. The tip is welded to a base portion by irradiating the interface between the base portion and the tip with the energy beam. The welding the tip to the base portion includes: applying the energy beam continuously, while moving the irradiation position of the energy beam, in a first period of time; and applying the energy beam a plurality of times according to a pulsed output pattern, while moving the irradiation position of the energy beam, in a second period of time subsequent to the first period of time.

摘要： Provided is a substrate holding member that includes a base body and a plurality of protrusions formed on a surface of the base body and that is capable of suppressing generation of particles due to peeling-off or cracking of protective layers of the protrusions. A substrate holding member includes a base body and a plurality of protrusions formed on a surface of the base body. Each of the protrusions includes a base portion and a protective layer, the base portion having a flat upper end surface and being made from a silicon carbide sintered compact, the protective layer being made of silicon carbide. The protective layer includes a region on at least a part of the base portion from an edge of the upper end surface to a lower end of the base portion, the region being exposed along an entire periphery. Preferably, the protective layer is formed so as to cover at least only a part of an upper portion of the base portion, the upper portion including the upper end surface.

摘要： A spark plug enabling suppression of reduction in the strength of an insulator. In the spark plug, a rear end portion of an engagement portion formed on an outer peripheral surface of a tubular insulator extending along an axial line from a front side to a rear side, is engaged with a to-be-engaged portion of a tubular metal shell disposed on the outer peripheral surface of the insulator. The insulator is made from ceramic such as alumina. On at least a part of the outer peripheral surface of the insulator, a projected and recessed portion is formed on the front side relative to the engagement portion so as to helically extend in a circumferential direction of the insulator.

摘要： An ignition plug such as a spark plug or a glow plug configured to ignite an air-fuel mixture in an internal combustion engine includes a mark that is formed of an oxide film generated on the surface of a metal member or is formed of the metal member and the oxide film. The mark is formed by promoting formation of the oxide film on the surface of the metal member or removing the oxide film through radiation of a laser beam onto the surface of the metal member.

摘要： An ignition plug includes a metallic shell containing iron as a main component, carbon in an amount of 0.20 wt. % to 0.30 wt. %, manganese in an amount of 0.30 wt. % to 0.45 wt. %, and sulfur in an amount of 0.005 wt. % to 0.009 wt. %. The ratio of the manganese content (wt. %) to the sulfur content (wt. %); i.e., Mn/S is 40 to 65.

摘要： A gas sensor includes a sensor element, metal terminals, a tubular separator that holds the metal terminals, lead wires connected to rear ends of the metal terminals, and an elastic member that holds the lead wires extending rearward from the separator. Each metal terminal includes a forward end portion electrically connected to an electrode portion, a central portion, and a lead wire connection portion. The forward end portion or the central portion is held by the separator. The central portion and the lead wire connection portion are connected to each other through a neck portion. The rearward-facing rearmost surface of the central portion is engaged with a forward-facing surface of the separator, and the circumferential length of a first connection portion between the central portion and the neck portion is longer than the circumferential length of a second connection portion between the lead wire connection portion and the neck portion.

摘要： Disclosed is a stacked-type plate-shaped sensor element for detecting the concentration of a specific gas component in a gas under measurement. The sensor element includes: a first ceramic layer; a pair of measurement and reference electrodes stacked on a front end part of the first ceramic layer; a through hole formed through at least the first ceramic layer in a rear end side of the sensor element; a through hole conductor disposed on an inner wall of the through hole; a porous reference lead extending between the reference electrode and the through hole conductor; a gas-impermeable second ceramic layer arranged on the first ceramic layer to cover at least the reference lead; and a ventilation portion provided, in the form of a hollow space or a porous substance, between the first and second ceramic layers at a position facing the through hole and communicating with the reference lead.

摘要： A fuel gas supply path in a fuel cell stack includes in series a first path, a second path, and a third path. In the second path, two inlets of the fuel gas in each of power generating cells included in the second path are located at a first position PA and a second position PB, and the position of one outlet of the fuel gas in each power generating cell is located at a third position PC. In the third path, an inlet of the fuel gas in each of power generating cells included in the third path is located at a position coinciding with the third position PC when the power generating cells are viewed in the stacking direction, and an outlet of the fuel gas in each power generating cell is located at a position between the first position PA and the second position PB.
