  • Patent number: 7914628
    Abstract: A magnetic material comprising a NaZn13 type crystal structure with uniform and fine microstructure exhibiting excellent characteristics as a magnetic refrigeration material, and a method of manufacturing the magnetic refrigeration material are provided. An alloy composition for forming magnetic material of the NaZn13 type crystal structure was melted comprising 0.5 atomic percent to 1.5 atomic percent of B to molten metal. The molten metal is rapidly cooled and solidified by a forced cooling process. Then, a rapidly cooled alloy having the NaZn13 type crystal structure was obtained. In this manner, magnetic materials comprising the NaZn13 type crystal structure phase, or the NaZn13 type crystal structure phase accompanied with other phases such as ?-Fe phase having very small phase regions was manufactured without requiring heat treatment for a long time. As the result, productivity of manufacturing the magnetic refrigeration material is remarkably enhanced.

  • Publication number: 20100201748
    Abstract: An object of the present invention is to provide an ink jet print head configured to reduce the inclination of an ink ejection direction to make improper print conditions such as stripes and density unevenness unnoticeable. To achieve the object, an individual wire is extended to lie under a common wire. Thus, wires under ink channels arranged on the respective opposite sides of a pressure chamber 40 are made symmetric. Consequently, an equivalent step structure is provided at the bottoms of the ink channels arranged on the respective opposite sides of a pressure chamber 40.
