Title: Rotation controller for astronomical dome
Inventor: NAKAMURA KATSUSHIGE
IPC: G02B23/16
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To accurately rotate an astronomical dome so that a slit may be always aligned with the top of a lens barrel by correcting a signal transmitted from a 1st control part to a driving part so that an actual rotational amount detected by a 2nd sensor may agree with a necessary rotational amount. SOLUTION: Information from two encoders 6 and 7 is transmitted to the 1st control part 10 so as to obtain the position of the top of the lens barrel 3 and calculate the necessary rotational amount of the astronomical dome 1. The dome 1 is rotated by a driving part 11 based on the signal from the control part 10. The actual rotational amount of the rotated dome 1 is detected by photoelectric sensors 8 and 9 and the detected information is transmitted to a 2nd control part 12. The control part 12 corrects the signal transmitted from the control part 10 to the driving part 11 so that the actual rotational amount detected by the sensors 8 and 9 may agree with the necessary rotational amount transmitted from the control part 10 as the signal. Thus, the dome 1 is accurately rotated by the necessary rotational amount even when the slip of a roller or the wear of the roller is caused in the driving part 11.

Abstract: PURPOSE:To make it possible to form a wiring structure which is effective for flattening the title wiring by a method wherein a wiring pattern is formed by an A,(alloy, a thin insulating layer containing Al is formed on the circumfer ence of the abovementioned wiring pattern, and a tapered side wall film is formed thereon. CONSTITUTION:The contact hole provided on the insulating film 3 on a semiconductor substrate 1 is filled up with polycrystalline silicon, an Al alloy film is deposited, and a wiring pattern 20 is formed. After this wafer has been dipped, the surface of the wiring is oxidized by projecting oxygen plasma, and an Al2O3 insulating layer 21 is formed around the wiring 20. Subsequently, an Al alloy film 22 is deposited again. Then, the whole surface is etched by a RIE method using BCl3 gas, and a tapered side wall 22' is formed on an Al pattern. Accordingly, this wiring is formed into the structure in which three rows of conductive layers are running in the longitudinal direction of the wiring through the intermediary of the insulating layer. Consequently, as the crystal grain field crossing the wiring is completely eliminated, the effect for prevention of disconnection of wire can be expected.

IPC: B27K5/00
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a black acacia wood of varying color and a method for manufacturing the black acacia wood. SOLUTION: The black acacia wood is manufactured under condition that it be dried at a high temperature, i.e., about 120 deg.C. Thus it is possible to obtain the black acacia wood which has turned dark brown as a whole. Even under these conditions, the black acacia wood is free from the generation of cracks and significant bends such as seen in other broad-leaved trees when thermally treated. Consequently, it is possible to assort the black acacia wood with a white to yellow texture obtained by drying at a low temperature and the black acacia wood with a dark brown texture by drying at a high temperature.
