Title: Method for dividing wafer
Inventor: NAGAI YUSUKE
IPC: H01L21/301
Filed: 2004-07-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for surely dividing a wafer when a modifying layer is formed by an irradiation with laser beams and the wafer is divided along a division predetermined line.  <P>SOLUTION: The method for dividing the wafer contains a modifying-layer forming step, in which the modifying layer is formed in the wafer 2 along the division predetermined line by laser beams, and a wafer supporting step in which the backside of the wafer is stuck on an extensible carrier tape mounted on an annular frame. The method further contains a dividing step in which the wafer is divided along the division predetermined line by expanding the carrier tape having the stuck wafer. In the dividing step, the carrier tape is expanded so that a tensile force working in the direction orthogonal to the division predetermined line extended in a given direction is made larger than that working in the direction orthogonal to the division predetermined line extended in the direction crossed with the given direction when the carrier tape having the stuck wafer is expanded. Accordingly, the wafer is divided first along the division predetermined line extended in the given direction, and divided successively along the division predetermined line extended in the direction crossed with the given direction in the dividing step.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Motor and enclosed electric compressor
Inventor: FUNAMI JUN
IPC: F04B39/00
Filed: 2004-07-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide an enclosed electric compressor, wherein the vibration of a stator due to torque fluctuation in a brushless motor for enclosed electric compressors is suppressed and noise is reduced.  <P>SOLUTION: A rotor constitutes a concentrated winding brushless motor for use in an enclosed electric compressor. The radius of curvature of the curved surface of the rotor is made larger than the reference radius. The air gap on the curved surface is varied to reduce rapid change in magnetic flux. Thus, the range of fluctuations in torque (torque ripples) produced due to change in magnetic flux is narrowed. As a result, vibration in the stator due to torque ripples is reduced, and a low-noise enclosed electric compressor is obtained.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
