摘要： A bonding method (three-dimensional mounting) of semiconductor substrates is provided to sequentially bond a principal surface of a silicon wafer on which coupling bumps are formed, and a principal surface of the other silicon wafer on which pads are formed, by an adhesive applied to at least one of the principal surfaces. However, there is a problem of poor electrical coupling due to displacement of the bumps and the pads when bonded together. The present invention solves such a problem by conducting temporary positioning of the silicon wafers, adjusting the positions of the coupling bumps and pads while confirming the positions by a method such as x-ray capable of passing through the silicon wafers, and bonding the bumps and the pads together while hardening an interlayer adhesive provided between the principal surfaces of the silicon wafers by thermocompression.

摘要： An electromagnetic contactor has a contact device including a pair of fixed contacts disposed maintaining a predetermined distance and a movable contact disposed to be capable of contacting to and separating from the pair of fixed contacts. The pair of fixed contacts each includes a support conductor portion supported by an upper plate of a contact housing case, and a contact conductor portion connected to an end portion of the support conductor portion. The contact conductor portion includes a contact plate portion formed with a contact portion, and a connecting plate portion formed on an outer end portion of the contact plate portion and extending to the upper plate side. The movable contact is mounted onto a connecting shaft connected to a drive portion through a contact spring on an end portion on the upper plate side, and disposed to face the contact portion of the pair of fixed contacts.

摘要： An electromagnetic contactor has a pair of fixed contacts; a movable contact disposed to be capable of contacting with and separating from the pair of fixed contacts; and an electromagnetic unit driving the movable contact. The electromagnetic unit has a magnetic yoke having an open upper part; an upper magnetic yoke cross-linked in the open upper part of the magnetic yoke; a spool having a central opening in which an exciting coil is wound around the spool; a movable plunger movably disposed in the central opening of the spool in an axial direction and having a tip end protruding, the movable plunger urged by a return spring; and an auxiliary yoke forming a magnetic path between the movable plunger and the U-shaped magnetic yoke when the movable plunger is in an open position. The movable plunger is coupled to the movable contact through a coupling shaft.
