摘要： PURPOSE:To prevent position slippage of a metal heating element for securing a prescribed heating quantity by making a linear metal heating element to be buried in a ceramic mold of a specific shape while sintering this by a HIP (hot isostatic press) method. CONSTITUTION:Provided that a linear metal heating element 6 to be buried in a ceramic mold 4 has the length l1, a wire diameter d1, the metal heating element 6 after sintering has the length l2, a wire diameter d2 and burning contraction ratio of a ceramic body is (rho) while being of the shape l1=l2.rho, d1=d2.rho , and this is sintered by an HIP method. Since the HIP sintering method is of extremely high sintering and the length direction of the linear part of the metal heating element 6 contracts at the same ratio with the burning contraction of the ceramic body, the value of the purposed l2 and d2 after sintering can be obtained, if the length l1, the wire diameter d1 of the metal heating element 6 at the charge time are so shaped as to satisfy the relation l1=l2.rho, d1=d2.rho . Thereby, an accurate ceramic sintered body having no gap and crack as well as prescribed resistance can be obtained.

摘要： PURPOSE:To manufacture a ceramic heater of a complicated form by sintering a substance to be sintered, wherein powder paste of a metal IV or VA group is buried between a pair of metal Si pressed powder molded substances under an N2 atmosphere for forming a sintered substance to be given hot hydrostatic treatment. CONSTITUTION:A substance to be sintered, wherein powder paste 3 of a metal IV A or VA group is buried between a pair of metal Si pressed powder molded substances 2 and 2', is sintered under an N2 atmosphere to form a sintered substance for being given hot hydrostatic treatment. Accordingly, at the time of sintering, metal IV A group or VA group powder paste 3 reacts to N2 to generate a conductive nitride, on the other hand, the metal Si pressed powder molded substances 2 and 2' are nitrided by N2 so as to obtain silicon nitride (Si3N4) ceramics by reaction sintering. Thereby, a ceramic heater 1 of a complicated form can be obtained.

摘要： PURPOSE:To reliably prevent the deterioration of the electrical heating wires due to oxidation thereof by bonding electrical connecting members to exposed terminals of the electrical heating wires embedded in a swirl chamber body and covering the bonded portions with an oxidation-resistant film. CONSTITUTION:A swirl chamber body is formed by embedding electrical heating wires 4 in a ceramic molding material and sintering same. Then, the swirl chamber body is cut at portions corresponding to terminals 4a of the electrical heating wires 4 to thereby expose the terminals 4a. Thereafter, electrical connecting members 5 are bonded to the terminal exposed portions by a brazing material 6, and then an oxidation-resistant film 7 is formed on bonded portions 8. Thus, it is possible to reliably prevent the deterioration of the terminals of the electrical heating wires due to oxidation thereof.

摘要： PURPOSE:To increase mechanical strength and corrosion resistance, by molding the heater body of a ceramic heater of conductive glowing ceramic material, in a glow plug which is fitted to the wall of an auxiliary combustion chamber so as to be projected in the auxiliary combustion chamber of an internal combustion engine. CONSTITUTION:A ceramic heater 2 has a bar type heater body 7 made of conductive glowing ceramic material. A non-oxidizable coating layer 10 of about 0.1mm thick, composed of such as silicon carbide (SiC) and silicon nitride (Si3N4) in order to inhibit oxidation of the heater body 7 contacting to the oxygen in atmosphere, is formed to coat the outer surface of a heater body 7 projecting from the end of a metallic sheath 3, by the method of ion plating or by CVD method. An Ni plating layer 11 is formed on the area of a heater body 7 where the non-oxidizable coating layer 10 is not formed. With the part on which the Ni plating layer 11 is formed being inserted into the hole 3a of the above- mentioned metallic sheath 3, the heater body 7 and the metallic sheath 3 are unitarily joined by a silver paste 12.

摘要： PURPOSE:To prevent a cavity member and a piston body from breakage by dispersing ceramic fiber in a piston of aluminum alloy, and by arranging an intermediate member between the piston body and cavity member of ceramic. CONSTITUTION:The body 1 of a piston is formed from aluminum alloy reinforced with ceramic fiber dispersed, and a cup-shaped cavity member 2 of ceramic is concentrically provided within the upper part of the piston body 1. Further the exterior surface of the cavity member 2 is covered with a cap- shaped intermediate member 5 consisting of a material with greater thermal expansion coefficient and smaller thermal conductivity than the piston body 1 such as naval brass. This prevents generation of a gap between the cavity member and piston body to lead to prevention of piston from breakage.
