摘要： PROBLEM TO BE SOLVED: To eliminate mixing of a pollutant, and improve a polishing speed by carrying child particles on a surface of a mother particle. SOLUTION: One or more kinds of child particles are carried on a surface of a mother particle. The average particle size of the mother particle is desirably in a range of about 0.3 to 30 μm, and more desirably in a range of about 0.2 to 5 μm. The average particle size of the child particles is desirably in a range of about 0.001 to 5 μm, and more desirably in a range of about 0.002 to 0.5 μm. A quantity of child particles carried on the surface of the mother particle is desirably in about 5 to 70 wt.%, and more desirably in a range of about 10 to 40 wt.%. When a slurry-like abrasive is adjusted by using such as composite particle, the composite particle is desirably included by about 0.5 to 30 wt.%, and more desirably in a range of about 1 to 10 wt.% to the whole abrasive quantity. When this abrasive is used, a pollutant is not mixed, and a polishing speed is improved.

摘要： PURPOSE:To prevent a damage of a feeder in the early stage by forming a metal membrane layer wider than the width of an electrode at the peripheral surface of the feeder. CONSTITUTION:Feeders 12 and 12 are provided at both ends of a rodform ceramic heater element 10, and at the peripheral surface of each feeder 12, a metal membrane layer 13 wider than the width of an electrode 14 is formed, and the electrode 14 is installed at the peripheral surface of each metal membrane layer 13. Consequently, the current is fed from a power source through one side lead wire 15, electrode 14, and metal membrane layer 13 to a heating part 11, it heats there, and after that, returns to the power source through the other side metal membrane layer 13, electrode 14, and lead wire 15. As a result, the heating temperature of the feeders can be suppressed at a low value.

摘要： PROBLEM TO BE SOLVED: To settle the apprehension regarding the influence of flying an organic solvent to exhaust facilities and human bodies by a method wherein a crosslinkable water-soluble binder is employed. SOLUTION: As the crosslinkable water-soluble binder used for the slip casting of ceramic, a binder, which crosslinks ceramic casting slip through crosslinking reaction to a hardness enough high and substantially has a water solubility, is employed. The preferable solubility (= the weight of solute/the weight of a solution) is about 10%. The preferable binder is a mixture of a crosslinkable component and a crosslinker. As the crosslinkable component, a water-soluble epoxy-based resin such as glycidyl ether or the like is exampled. As the crosslinker, an amine-based compound is exampled. By employing a binder mainly made of a crosslinked body including the water-soluble epoxy- based resin and the amine-based compound, there is no apprehension regarding the exhaustion of an organic solvent and the influence to human bodies and a formation, in which no crack or the like develops even after the hardening through reaction and after the baking of a ceramic formed body.

摘要： PROBLEM TO BE SOLVED: To accurately measure a low oxygen concentration of a ppm level by including a solid electrolyte having ion conductivity and low electron conductivity in a solid electrolyte layer where a heat resistant impact temperature has the ion conductivity of a specified temperature. SOLUTION: For oxygen measuring, an oxygen ion conductive solid electrolyte, for instance yttria zirconium is preferred, but it is weak to heat resistant impacts and therefor it is not suited for a casting sensor. Thus, a solid electrolyte layer is constructed in such a manner that a one end sealed tube 1 (Tammanin tube) is composed by using a solid electrolyte having ion conductivity where a heat resistant impact temperature is 120 deg.C or higher, for instance, magnesia zirconium, and an yttria zirconium film 5 is coated on a range of the standard pole of its inner surface having a reference material 2. Thus, since a temperature increase gradient is softer compared with the outer surface of Tammanin tube 1, the film 5 is not damaged, a sensor having small partial electron conductivity and large oxygen ion conductivity is provided and low oxygen concentration is accurately measured.

摘要： PURPOSE:To enhance the accuracy of measurement and to increase response speed by providing porous electrodes and fine particles of a solid electrolyte, etc., and operating the title sensor at a relatively low temp. CONSTITUTION:The electromotive force based on a difference between the oxygen partial pressures of a reference gas of a known oxygen partial pressure and a gas to be measured is generated between the porous electrodes 2 and 3 when the above-mentioned reference gas is introduced into the sensor from a reference gas introducing pipe 9 and the gas to be measured is introduced into an outside pipe 8. This electromotive force is, therefore, measured by an electromotive force meter 10 to determine the oxygen partial pressure of the gas to be measured. The gaseous oxygen in closed cells 7 is discharged by the oxygen pump effect of the fine particles 5 of the solid electrolyte or the gaseous oxygen is introduced therein from the contact gas even if the closed cells 7 exist in the electrodes 2, 3 and, therefore, the oxygen partial pressure of the gas in the cells 7 equilibrates rapidly with the oxygen partial pressure of the contact gas. The sensor is operated at the relatively low temp. in such a manner. The accuracy of the measurement is thus enhanced and the response speed is increased.
