High-pressure-resistant hermetic seal terminal and method of manufacturing the same
A high-pressure-resistant hermetic seal terminal includes an eyelet which has a through hole and a lead which is electrically insulated and hermetically sealed via a glass material in the through hole. The glass material is welded in a manner to extend on a lower surface of the eyelet from an end of the through hole to surroundings of the end of the through hole. Preferably, the eyelet has a counterbore, in the lower surface, extending in a region around and surrounding the through hole, and the glass material is welded to the inside of the counterbore.
An object of the present invention is to provide a chip-size packaging device at low cost that achieves size reduction, thickness reduction, weight reduction, and further, high reliability, by using a glass substrate with a through electrode. The packaging device according to the present invention is characterized in that a glass substrate having a plurality of through electrodes arranged at a predetermined position is used as a base member for a package that houses a device element having a group of electrodes, and the group of electrodes and the through electrodes are led out to an external circuit with a contact medium arranged to bypass a sealant being interposed between the group of electrodes and the through electrodes.
A thermal fuse employing a thermosensitive pellet is provided, which exhibits stabilized characteristics in a low operating temperature region. The thermal fuse includes at least a switching movable member, a thermosensitive pellet member, a pair of leads having a first lead portion and a second lead portion, and a metal casing. The thermosensitive pellet member contains a polyolefin wax. The thermosensitive pellet member is housed in the metal casing to which the pair of leads are attached. The switching movable member is operated by deformation associated with softening or melting of the thermosensitive pellet member, to attain a cut-off state between the pair of leads. The thermal fuse employing a thermosensitive pellet is suitable for an operating temperature of 50 to 180° C. Furthermore, in the thermosensitive pellet member the polyolefin wax is mixed with a thermoplastic resin as appropriate, to thereby provide a thermal fuse employing a thermosensitive pellet which increases the response speed while maintaining the operating temperature with high accuracy.
