Title: Satellite tracking system and method
Inventor: MURAKAMI TOMOKI
IPC: H01Q3/04
Filed: 2001-02-21
Abstract: PROBLEM TO BE SOLVED: To solve such problems in a satellite tracking system, which calculates the orbit of a satellite by using obtained positional information as a real value for waitingly receiving with an antenna directed to a satellite appearance anticipated direction before the satellite appears in a visible area, that the antenna cannot rightly catch and track the satellite due to errors included in the positional information when the satellite enters into the visible area. SOLUTION: Past positional information is stored in a positional information storage device 5 and past orbit 31 of the satellite 12 is calculated based on the latest satellite positional information 30. A positional information evaluation device 6 compares the last antenna anticipation value calculated based on the orbit and past actual control data (namely, the last-time orbit) of the antenna stored in a real antenna control value storage device 7 and evaluate the reliability of the positional information 30 by the largeness/smallness of the difference therebetween. When the difference is large, more precise one is selected from the past satellite positional information and only the positional information evaluated to have the reliability is inputted in a orbit calculator 2.

Title: Variable pitch wear resistant structure for rotor blade
Inventor: HARA KENICHI
IPC: B63H3/04
Filed: 2001-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent the sticking of a rotor blade shaft arm and an arm piece at a contact surface. SOLUTION: A flange part 52 of a flanged bush 51 composed of self- lubricating material is extended to provide a step part 16 on the contact surface 40 of the arm piece 10 and the rotor blade shaft arm 20. The flanged bush 51 is incorporated in an arm shaft attachment hole 11 of the arm piece 10 and the flange part 52 of the flanged bush 51 extends out to the step part 16 of the arm piece 10. Since the thickness of the extended flange part 52 is larger than the depth of the step part 16 of the arm piece 10, the flange part 52 gets into contact with the rotor blade shaft arm 20. Since friction resistance between the rotor blade shaft arm 20 and the arm piece 10 is greatly reduced and wear is almost eliminated with this kind of structure, the sticking of the arm piece 10 and the rotor blade shaft arm 20 is prevented even if both of those slide during rotor blade pitch change.

Inventor: IGUSHI HIROAKI
IPC: G01L27/00
Filed: 2001-03-01
Abstract: PROBLEM TO BE SOLVED: To make a pressure detector easily correctable with respect to the atmospheric pressure. SOLUTION: A signal for opening a pressure applied to a pressure detector 1 to the atmospheric pressure may be outputted for atmospheric pressure correction. The signal may be outputted by pressing as switch (not shown in the figure), etc., provided to an operation panel of the pressure detector 1.
