摘要： PROBLEM TO BE SOLVED: To easily specify a defective place by soaking the injection nozzle tip in liquid by detecting an injection nozzle inside infiltrating degree of the liquid by a capillary phenomenon by measuring a weight change, finding a liquid level rising position from the detecting value, and judging a work defective place of an injection nozzle. SOLUTION: When nozzle port work of an injector nozzle 1 is inspected, the nozzle tip is soaked in liquid 5. At this time, a liquid level 4 of the liquid 5 is put in a state of rising above a guide 2 in a work nondefective good sample (a). Hewever, the liquid level 4 stays in a nozzle port part in a sample (b) defective in the nozzle port part, and the liquid lever 4 stays in a guide lower part in a lower part defective sample (c) of the guide 2. The liquid level 4 stays in a guide upper part in an upper part defective sample (d) of the guide 2. Then, a work defect is discriminated from a correlation between a defective place and a liquid infiltrating quantity by measuring an infiltrating quantity of liquid by a weight change in the nozzle 1.

摘要： PURPOSE:To provide conductive paste for a piezoelectric element which can sufficiently display primary electric characteristic of the piezoelectric element, a large displacement amount. CONSTITUTION:Glass precursor organic substance, which is decomposed so as to react to form glass by heating, is used as a glass component. The glass precursor organic substance is decomposed by heating, and reacts with oxygen in the atmosphere so as to react mutually to be fine glasses 4. The fine glasses 4 are produced on the interfaces of gold particles 3 and the interface of a piezoelectric element 1 so as to combine the gold-particles 3 unitedly and to bond the same to the piezoelectric element 1 firmly. Thereby excellent ohmic contact characteristic between the piezoelectric element 1 and the gold particles 3 is ensured so that the piezoelectric element 1 holds a large displacement amount.
