Title: Reflecting mirror for parabolic antenna
Inventor: INOUE NOBUTAKA
IPC: H01Q15/16
Filed: 1990-03-23
Abstract: PURPOSE:To increase a gain and to attain low pricing by realizing mass production by using a member in which the chemical plating of metal with good conductivity is applied to chemical fiber woven by specifing weaving density as the reflecting member of a reflecting mirror. CONSTITUTION:The member in which the chemical fiber is woven is used as the reflecting member 8. Thereby, a mesh can be prevented expanded irregularly, and the member can be embedded in a base material keeping uniform mesh. The reflecting member 8 is comprised of the member in which the chemical plating of the metal with good conductivity is applied to the chemical fiber is woven in the weaving density of 100-300/in. Therefore, a sufficient small gap between the meshes can be obtained for wavelength sent from a broadcast satellite or a communication satellite. Therefore, a microwave from the satellite, etc., to the reflecting mirror 5 can be reflected with high reflectance, and advances to a primary radiator 16. Consequently, the microwaves arriving at any plane can be accurately collected on the primary radiator. Also, it is possible to reduce a cost by using a reflecting member more inexpensive than a metal net even without using a reinforcing net.

Title: Simulation device of position detector
Inventor: YAMAGUCHI KATSUMI
IPC: G08C19/38
Filed: 1978-06-23
Abstract: PURPOSE: To minimize errors by using a digital-synchro converter in a position detection unit.  
     CONSTITUTION: AC voltage differences required between input terminals A and B and between B and C of position display 5 are produced by a digital-synchro converter. An AC power supply is connected to both terminals R 1  and R 2  of the reference coil of this digital-synchro converter. Three coils one end of which is connected to each other are rotated by the control of a computer. AC voltage differences proportional to the angles of rotation of these coils are produced on the other terminals S 1 , S 2  and S 3 . Thus, since it is not necessary to use a mechanical system for the transmission of position signals, it is possible to perform high-precision position display with less transmission error variation.
