Abstract: Cup ring 8 and holding-plate 11, disposed at each side of front bracket 7, sandwich tightly an outer ring of front ball-bearing 10 in order to prevent creep between a bearing housing and the outer ring. A thickness of bearing shim 12 is adjusted such that an axial clearance between the front ball-bearing and a rear ball-bearing falls within a range from 0.02 to 0.1 mm. Holding plate 11 is temporarily fixed to a given place of motor shaft 1, then screwed down thereto with screw 14, so that plate 11 moves and solidly contacts with the outer ring of front ball bearing 10. An outer diameter of shaft 1 extending between the given place and bearing 10 is smaller than a center hole of holding plate 11, thus plate 11 does not touch shaft 1.

Abstract: To generate a command for dealing with error message from accumulated information and transmit the command to information processing as transmission place, a process analyzes error message received by a communication process, searches file based on analysis of the error message, and searches file based on search, to acquire related message.

Abstract: When electrodes on an electronic component and electrode portions on a circuit board are joined via bumps with the electronic component and the circuit board vibrated respectively, a vibration damping detect device and a deciding device detect damping of the vibration caused by a progress of joining between the bumps and the electrode portions, and then determine a good or defective of the joining on a basis of the damping of the vibration. Further, regarding an impedance of an ultrasonic oscillator, a movement amount of a nozzle, or a current supplying to a VCM, these waveforms during the joining are compared with waveforms of good joining thereof and then the good or defective is determined. According to the above constructions, the good or defective of the joining between the electronic component and the circuit board can be determined during the joining. Further, when a joining state becomes wrong during the joining, the joining state can be changed.

Abstract: The present invention provides a bump-joining apparatus, a bump-joining method, and a semiconductor component-manufacturing apparatus whereby bumps and electrode portions of circuit board are perfectly joined with higher join strength than in the conventional art. The apparatus includes a vibration generation device, a pressing device and a control unit, wherein bumps are pressed to electrode portions of a circuit board and vibrated with ultrasonic waves after reaching an initial contact area before reaching a join-completed-contact area at a completion of the joining, so that the bumps are more perfectly joined to the electrode portion than in the conventional art which vibrates the bump only after reaching the join-completed-contact area. Larger join strength is achieved than in the conventional art.
