摘要： The electromagnetic contactor enables a reliable return to a pole open position without increasing the spring force of a return spring. In an electromagnetic contactor, an electromagnetic device having an exciting coil and a contact mechanism having a return spring are disposed in parallel, and the electromagnetic device and contact mechanism are linked by a drive lever. The electromagnetic device has a polarized electromagnet having a magnetic circuit that includes a permanent magnet generating a suction force that moves the contact mechanism to a pole open position side when the exciting coil is not energized. The drive lever is fixed to either one of the electromagnetic device or contact mechanism and contacts with the other with no gap at least when the contact mechanism is moved to the pole open position side. The return force of the contact mechanism is covered by the suction force of the permanent magnet.

摘要： A life prediction method of an electronic device in which the life prediction accuracy is more improved than that in a related art technique, and a design method of an electronic device based on the above method, are established. Life prediction is performed by incorporating either of a change in a physical property of a solder joint portion and a change in the fatigue life of a solder, the changes occurring when left at a high temperature. The change in a physical property of the solder joint portion or the change in the fatigue life of the solder is determined from the relationship between a heat treatment temperature and a heat treatment time. These changes are then formulated to be incorporated into the life prediction.

摘要： To prevent peeling-off of a film in a solder connection pad of a semiconductor device, which peeling-off may occur due to thermal load and so on in the manufacture process, a pad structure is adopted in which a Cr film good in adhesiveness to either of a Ti film or Ti compound film and a Ni film (or a Cu film) is interposed between the Ti film or Ti compound film formed on a silicon or silicon oxide film, and the Ni film (or the Cu film) to be connected to solder. Further, to prevent peeling-off at the interface between the Ti film or Ti compound film and the silicon oxide film, the Cr film is formed in a larger area than the Ti film or Ti compound film.

摘要： An optical fiber preform (1) serving as a material of an optical fiber has a shoulder portion (12) thrusting beyond a middle portion (M) in a base end region (K) which is on the upper side when the optical fiber preform is suspended for a drawing process. The optical fiber preform (1) of this configuration can be easily produced by appropriately setting the heating condition, etc. for the sintering step in the production process. Thus, it is possible to omit the elongating step after the sintering step, thereby simplifying the production process. Further, in the prior-art technique, turbulence is generated in the gas flow in the furnace of the drawing apparatus toward the end of the drawing step, making it impossible to draw in a stable manner. In contrast, in this embodiment, due to the shoulder portion (12), there is a small gap between the inner wall surface of the furnace and the optical fiber preform; due to this small gap, the gas flow is regulated, and the drawing can be conducted in a stable manner even toward the end of the drawing step.
