  • Patent number: 11935700
    Abstract: A laminated electronic component includes an element body formed by laminating an insulating layer and having a bottom surface used as a mounting surface, and a bottom surface electrode formed on the bottom surface of the element body and containing glass and a sintered metal. The bottom surface electrode includes a first electrode layer and a second electrode layer formed on the element body side from the first electrode layer, an edge portion of the second electrode layer is covered with an overcoat layer which is a part of the element body, the first electrode layer is laminated on the second electrode layer with the overcoat layer interposed therebetween, and a content of glass in the first electrode layer is larger than a content of glass in the second electrode layer.

  • Patent number: 6224684
    Abstract: By a process of crystallizing raffinose under cooling, raffinose is efficiently crystallized, by continuously or intermittently circulating a solution containing raffinose, whereby temperature control can be done rapidly and accurately and laborious works for removing raffinose crystals adhered to the container are never needed because raffinose crystals are not adhered to the crystallization container under cooling, leading to the elevation of the yield, so the invention is excellent as a system for producing raffinose crystals industrially, in particular.
