    摘要： Provided is a piezoelectric element comprising a piezoelectric layer and an electrode. The piezoelectric layer includes a solid solution of bismuth lanthanum titanate zincate and lead titanate. The molar ratio of the bismuth lanthanum titanate zincate to the lead titanate in the piezoelectric layer is 0.39 or more and 0.61 or less.

    摘要： A service-area road that is a road in a service area such as a rest area or parking area of an expressway is determined to be a road on which a vehicle travels on when the following three conditions are satisfied. A first condition is satisfied when the vehicle travels in an expressway. A second condition is satisfied when a main road of the expressway and the service-area road are designated as candidate roads in map matching process. A third condition is satisfied when a difference between the heading direction of the vehicle and the traffic direction of the main road is equal to or greater than a predetermined value. Thus, it can be as promptly as possible determined that the vehicle is traveling on the service-area road, allowing the vehicle mark to be accurately displayed on the service-area road on the displayed map.

    摘要： A method of preparing a polyvinyl alcohol hydrogel contains the steps of charging an aqueous solution of a polyvinyl alcohol having a degree of hydrolysis of not less than 95 mol % and an average polymerization degree of not less than 500 into a container, the aqueous solution containing the polyvinyl alcohol in a concentration of not less than 5 wt. %, cooling the aqueous solution of the polyvinyl alcohol at a temperature of from - (minus) 9.degree. C. to - (minus) 3.degree. C., subjecting the aqueous solution of the polyvinyl alcohol to physical stimulation, and then maintaining the aqueous solution of the polyvinyl alcohol at a temperature of from - (minus) 5.degree. C. to + (plus) 5.degree. C. The polyvinyl alcohol hydrogel may be contained in a plastic container. An MRI phanton is composed of the plastic container containing such polyvinyl alcohol hydrogel.
