A non-linear element, such as a diode, in which an oxide semiconductor is used and a rectification property is favorable is provided. The eyelet defines two entryexit void regions and a central void region extending between the entryexit void regions. Another aspect of the indium tin oxide powder has a modified surface, wherein a specific surface area is 40 m2g or more, a half-width in the peak of plane is 0. In the preferred embodiment, identification of the data header sector is completed by analyzing only the first few bytes of the sector. The ensemble is manufactured by attaching the rubber foam insulating jacket to the outer surface of the vessel using a dual durometer process which creates a fusion that is much stronger than an adhesive or friction.
