Abstract: A translucent ceramic contains a main component composed of a tungsten-bronze-type compound represented by a general formula {(Sr, Ba)NbvOw} (wherein v satisfies the relationship 1.8?v?2.2 and w represents a positive number for maintaining electrical neutrality), wherein some Nb atoms are replaced with atoms of at least one of Zn and Mg, and the replacement ratio is 0.004 or more in terms of the molar ratio. It is preferable that at least one of Sn and Bi is added in an amount of 0.15 parts by weight or more in terms of SnO2 and Bi2O3, respectively, to 100 parts by weight of the main component, and that the molar ratio of Ba in the (Sr, Ba) site is in the range of 0.25 to 0.50. It is also preferable that the translucent ceramic contains Na in an amount of less than 25 parts by mole relative to 100 parts by mole of the sum of Sr and Ba, or La in an amount of less than 11 moles relative to 100 parts by mole of the sum of Sr and Ba.

Abstract: A separable die including a plurality of molding through holes is disposed in a recess in a cavity of a molding die. Slurry containing a ceramic powder and a solvent is supplied in the cavity. The slurry in the cavity is then pressed into the molding holes of the separable die by pressure due to a movement of a punch. Excess solvent is removed by suction by a stage for suction dewatering provided at the rear of the separable die thereby forming green compacts in the molding holes. Subsequently, the separable die is removed from the molding die. The green compacts are released from the molding holes of the separable die in a separate state.

Abstract: There is disclosed a method for adjusting the temperature coefficient of resistance (TCR) of a temperature-measuring resistive element comprising an electrically insulating base and a platinum film formed on the base. The platinum film is formed by sintering an organic platinum compound. The temperature coefficient of resistance (TCR) is adjusted by controlling either the temperature at which the platinum film is heat-treated after the formation of the platinum film or the thickness of the platinum film.

Abstract: A platinum temperature sensor showing excellent sensitivity to heat. The sensor comprises an insulating substrate having a support portion at one end of the substrate. A heat-generating portion is formed by a platinum film circuit at the other end of the substrate. A coating made from a material having a low thermal conductivity is formed on the support portion of the insulating substrate to suppress dissipation of heat from the support portion. A first heat-insulating gap is created between an end portion of the platinum film circuit and the heat-generating portion. A second heat-insulating gap is created between the platinum film circuit and the coating.

Abstract: A platinum temperature sensor includes a meandering pattern portion and outlet portions continuously connected to respective ends thereof which are defined by a platinum film which is formed on an insulating substrate. External electrodes are formed to cover the outlet portions as well as the ends of the insulating substrate provided with the outlet portions. Each of the external electrodes comprises a first layer containing platinum or nickel which is in contact with the outlet portion and with the insulating substrate, a second layer containing silver and platinum which is formed on the first layer, a third layer containing nickel which is formed on the second layer, and a fourth layer containing tin or solder which is formed on the third layer. The first layer suppresses diffusion of silver contained in the second layer, and the third layer improves heat resistance of the second layer, while the fourth layer improves solderability.

Abstract: A method of manufacturing a platinum temperature sensor includes the step of obtaining a meandering resistive circuit by forming grooves in a platinum film which is provided on an insulating substrate. In order to provide a high resistance value by reducing the line width of the resistive circuit, as well as to miniaturize the platinum temperature sensor, this method comprises steps of forming a resist film on the platinum film provided on the insulating substrate, patterning the resist film by photolithography, and using the patterned resist film as a mask to finely work the platinum film by Ar.sup.+ ion etching for forming the grooves. Due to formation of such grooves, the platinum film defines a meandering pattern portion which provides the resistive circuit.
