Abstract: <P>PROBLEM TO BE SOLVED: To provide a device for laser beam machining capable of optionally setting a machining start position in relation to a moving object, and to maximize the use of the central part as the area for scanning laser beam, which relatively dominates the machining precision aspect in a machining area.  <P>SOLUTION: An area for scanning laser beam to a machining object under sending is established near the center of the machining area. The machining start position is changed from A to A" to center the area for scanning laser beam, and the machining process is started when the machining object reach A". Therefor, a machining process is done from A" to B", and the machining path, i.e. the scanning pattern is moved to the center as compared with the machining from A to B'. As the start position is established so that the middle point of AB' is the center of the machining area, the laser beam is scanned near the center of the machining area and the accurate machining is realized.  <P>COPYRIGHT: (C)2004,JPO

Title: Coil component
Inventor: SUGIYAMA YUJI
IPC: H01F17/00
Filed: 2002-07-24
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the size of a coil component while the occurrence of problems caused by a via hole 5 is suppressed.  <P>SOLUTION: In this multilayered coil component 1, the number of turns of one 3S of coil patterns 3S and 3L connected to each other through the via hole 5 is made smaller than that of the other coil pattern 3L. Though the winding route of the many turn-side coil pattern 3L is almost fixed and the degree of freedom for design of the pattern 3L is low, the degree of freedom for setting the winding route of the less-turn side coil pattern 3L becomes higher accordingly to the reduced number of turns of the pattern 3S. The forming position of the via hole 5 is decided based on the winding route of the many-turn side coil pattern 3L, and the winding route of the less-turn side coil pattern 3S is set based on the forming position of the via hole 5 so that the occurrence of problems (namely, the short-circuiting of terminal sections with the middle portion of the winding route) caused by the via hole 5 may be prevented. A drop in inductance value can be suppressed by increasing the number of turns of the many-turn side coil pattern 3L by the reduced number of turns of the less-turn side coil pattern 3S.  <P>COPYRIGHT: (C)2004,JPO
