Title: Contact detection system
Inventor: ONO TETSUJI
IPC: G01B11/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a contact detecting system for preventing the damage to a mask, and for reducing the generation of power dusts to the minimum by quickly and surely detecting the contact of a mask with a wafer. SOLUTION: A wafer mark 12 and a mask mark 14 are image-formed with a video camera 15 in the oblique direction. A picture processor 16 calculates the coordinate positions of the wafer mark and the mask mark based on picture information from the video camera. A contact detecting device calculates the movement of the coordinate position of each mark, and obtains correlation with the driving information from a machine controller for operating the position control of the wafer and the mask. When the correlation is deteriorated, it is judged that the wafer or the mask is unnaturally moved, and that the wafer is brought into contact with the mask.

Title: Three level inverter
Inventor: MATSUMOTO HISAAKI
IPC: H02M7/5387
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To suppress the effect of parasitic inductance in wiring structure by arranging main circuit conductors such that a first conductor runs in parallel with second and third conductors. SOLUTION: A second conductor 32a is stood from the positive potential side of a first switching element 21a perpendicularly to the axis of a stack 23 and then shifted to the center while substantially keeping parallelism with the axis of the stack. On the other hand, a third conductor 32b is stood from the negative potential side of a fourth switching element 21d perpendicularly to the axis of the stack 23 and then shifted to the center while substantially keeping parallelism with the axis of the stack. Furthermore, a first conductor 33 is laid between the second and third conductor 32a, 32b substantially in parallel therewith. Since currents flow in reverse direction at the part of current route running in parallel, self inductance is canceled by mutual inductance and the total inductance can be minimized.
