Abstract: Provided is a displacement sensor which allows at least part of the data used from the time of obtaining an image until the time of computing the displacement can be readily verified. In a displacement sensor for automatically extracting a coordinate of a measuring point from an image obtained by using an imaging device according to a prescribed measuring point extraction algorithm, and computing a desired displacement from the automatically extracted measuring point coordinate, the sensor is further provided with the function to edit data used from the time of obtaining the image until the time of computing the displacement for use as display data for an image monitor.

Abstract: A monolithic electronic element is fabricated from a semiconducting ceramic, which element can be produced through firing at 1000° C. or lower and exhibits a satisfactory PTC characteristic even when the element is produced through reoxidation at low temperature. The monolithic electronic element 1 includes a sintered laminate 3 formed of alternatingly stacked semiconducting ceramic layers 5 and internal electrode layers 7, and external electrodes 9 formed on the sintered laminate, wherein the semiconducting ceramic layers 5 comprise sintered barium titanate containing boron oxide; an oxide of at least one metal selected from among barium, strontium, calcium, lead, yttrium and a rare earth element; the boron oxide being incorporated in an amount, as reduced to atomic boron (B), satisfying the following relationships: 0.001≦B/&bgr;≦0.50 and 0.5≦B/(&agr;−&bgr;)≦10.

Abstract: A process for molding a resin-laminated rubber closure for a medical vial. This closure includes an annular leg part to be inserted into the mouth of the vial, which leg part is notched or cut at least at one position and a flange part to be contacted with the front surface of the vial mouth. The outer and inner surfaces of the annular leg part are laminated with a chemical-resistant resin film except for the upper end of the leg part so that the rubber surface is exposed at the upper end of said leg portion. The leg part has at least one protrusion on the outer surface of the laminated portion.
