Title: Absolute position correction device for structure installed on ground with respect to fluctuation of its foundation
Inventor: MATSUI NOBUYUKI
IPC: H01Q3/02
Filed: 1991-03-25
Abstract: PURPOSE:To correct the displacement of the structure installed on ground with respect to fluctuation in its foundation by using a slide table freely slided in two orthogonal directions provided on four corners of the structure and using an extraction/contraction jack of a support device linked to the table. CONSTITUTION:The correction device J and an X, Y slide table T are fixed to four corners of the structure. Then the X, Y, Z displacement of the support by an expansion/contract jack 1 of the XY slide table T is measured and a tilt is corrected by adjusting a stroke of upper and lower grippers 11, 12. Moreover, a level is corrected by adjusting the stroke of the expansion/contract jack 1 by a vertical weight reception out-rigger 10 after the tilt is corrected. Furthermore, a horizontal displacement is corrected after the displacement of the XY slide table is absorbed in parallel with the tilt correction. Thus, the displacement in the absolute position of the antenna platform is corrected to eliminate any hindrance on reception.

Title: Dry etching method
Inventor: AKIBA NAMISATO
IPC: H01L21/302
Filed: 1993-02-25
Abstract: PURPOSE:To prevent the generation of an Al crown at the time of forming a via hole on an Al-based wiring layer. CONSTITUTION:An SiO2 interlayer insulating film 2 on an Al-1% Si layer 1 is etched by using a mixed gas of c-C4F8/CH2F2 in a magneto-microwave plasma etching device which can generate high-density plasma having an ion density of >=10<11> ions/cm<3>. Since a reactive layer 6 having a low vapor pressure is formed on the exposed surface of the layer 1 when the formation of a via hole 5 is completed, the layer 6 is utilized to the accomplishment of high selectivity in this etching by adjusting the incident ion energy to such an extent that the layer 6 is not sputtered. However, the etching rate is maintained at a practical level, since a large amount of CF<+> is generated in the high-density plasma. The sputtering of the layer 1 is reduced and the generation of an Al crown is prevented.
