Title: Method for detecting soldering failure in ic terminal by tuning type sensor coil
Inventor: KADOKURA AKIRA
IPC: B23K1/00
Filed: 2000-07-18
Abstract: PROBLEM TO BE SOLVED: To electrically detect the soldering of an IC terminal at a high speed. SOLUTION: A tuning type sensor coil provided with a sensor coil formed by winding a plurality of conductive coils on a cylindrical bobbin formed of a magnetic material core such as ferrite or the like having a diameter conformed to the outer dimension of an IC and a capacitor connected to the output end of the sensor coil, is set on the IC. A means for applying an AC (sine wave, pulse, etc.), signal to a measuring terminal in the IC grounded except the measuring terminal to detect the magnetic field generated by the current carried to a protective diode within the IC by the tuning type sensor coil set on the IC is given to all the IC terminals. The propriety is judged by the comparison with a preliminarily stored reference value for non-defective IC.

Title: Motor
Inventor: ABE MAKOTO
IPC: H02K1/17
Filed: 2000-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a motor where precise and less intensive magnetic flux control can be conducted. SOLUTION: A bar-like magnetic material 13 is formed in the flux barrier 10 of a stator core 7, so that the magnetic material can be advanced and retreated freely in the axial direction. The amount of advance/retreat of the bar-like magnetic material 13 is adjustable according to number of revolutions. When the bar-like magnetic material 13 is advanced into the flux barrier 10 during high-speed revolution a part, of the magnetic flux of the permanent magnets 9 leaks around through the bar-like magnetic material 13. As a result, the magnetic flux which is linked to the rotor core 6 is reduced, and thus substantially less intensive magnetic flux control can be exercised with precision.
