  • Piezoelectric element and injector using the same
    Patent number: 6845920
    Abstract: A piezoelectric element and an injector using the same piezoelectric element are disclosed, which are so high in reliability as not to be shorted even in a high humidity environment, are small in size, are low in cost and are high in heat radiation capability. The piezoelectric element comprises a ceramic laminate (10) including a plurality of ceramic layers of a piezoelectric ceramic (11) and a plurality of internal electrode layers (21, 22), stacked alternately. At least an organic insulating layer (41) of an organic material is formed on at least a part of the surface of the ceramic laminate (10), and at least an inorganic insulating layer (42) of an inorganic material is formed on the organic insulating layer (41).

  • Method for manufacturing organic EL device with protective layer
    Publication number: 20030129298
    Abstract: An organic EL device has a structure in which an anode, a hole transporting layer, an organic luminescent layer, and a cathode are disposed on a glass substrate in this order. The organic EL device further has a protective layer covering an outer surface of the structure to protect it from an external environment. The protective layer is formed by an ALE method at a temperature lower than glass transition temperatures materials constituting the hole transporting layer and the organic luminescent layer.
