The conductive wire rod comprises a coil of a metal wire. The coil is formed helically along its whole length, and the winding pitch of the coil is set small, large and small in this order from the front end portion of the shell of the protective pipe toward its base end portion.

摘要： A slidable ceramic member includes a base of a sintered ceramic material which is a compound including silicon (Si) as a constituent element, the base having a sliding surface, and a coated layer covering the sliding surface of the base, the coated layer comprising a compound of elements, such as barium (Ba) and calcium (Ca), belonging to group IIa of the periodic table, silicon (Si), and oxygen (O). The slidable ceramic member is used as a slidable component of a heat engine such as a cylinder liner or a piston ring which is subjected to repeated thermal stresses. Such a slidable ceramic member is manufactured by placing powder of a fluoride including elements belonging to group IIa of the periodic table on a surface of a base, and heating the base while rubbing the powder against the surface of the base, whereby the silicon (Si) contained in the base and the group-IIa elements contained in the powder can react with each other, thereby forming a slidable layer on the surface of the base.

摘要： [0081] A thermocouple lance for measuring temperatures in molten metals has a protective sheath of multi-layered structure that makes it possible to improve the life expectancy of repetitive measuring devices. The thermocouple lance has a protective sheath with one closed end and one opened end wherein porous heat-resisting ceramic filler is compacted. Embedded in the filler is a pair of W—Re alloy wires dissimilar in their composition from each other. The protective sheath has a layered structure made from cermet layers each having a molybdenum matrix and other layers of at least one boundary layer selected from the class consisting of C, MgO, CaO, Al2O3 and ZrO2, the cermet layers and boundary layers overlapping each other in alternate layers. At least the outermost shell layer of the protective sheath is made of a cermet layer composed of any one of Mo—ZrN, Mo—ZrB2, Mo—ZrO2, Mo—ZrC and composite thereof. In one embodiment, a protective sheath is composed of layers in which are embedded filaments oriented predominantly in the circumferential direction of the sheath, and boundary layers which are provided between confronting surfaces of any adjoining filament-embedded layers, the boundary layer being weaker in bonding power than the filament-embedded layers. The filaments are of carbon or ceramic whereby the protective sheath may be enhanced in strength against the tensile stress that will occur due to the temperature difference in the protective sheath.

摘要： This ceramic heater is increased in bulk density and decreased in production cost by using an unsintered composite as an unsintered filling member filled in a protective pipe without application thereto of a filling pressure while preventing a heating element from deteriorating. In this ceramic heater, the heating element capable of heating by flowing electricity therethrough is disposed in the protective pipe, which is filled with the unsintered composite. In the unsintered composite, inorganic compound particles are disposed between insulating ceramic particles. In this ceramic heater, the heating element is fixed to the inner wall surface of the protective pipe with a heat-resistant glass layer. The heat-resistant glass layer is partially penetrated into the unsintered composite. The open end portion of the protective pipe is hermetically sealed with a heat-resistant sealing member while allowing extension of lead wires from the end portion of the protective pipe.
