Title: Carrier wave frequency error detector
Inventor: IWASAKI HIROYA
IPC: H04B7/26
Filed: 1989-11-30
Abstract: PURPOSE:To estimate the carrier wave frequency error in a short time by varying a local oscillation signal outputted from a local oscillator in accordance with a prescribed rule, and executing the Fourier-transformation again, when a ratio of the maximum value and the next largest value is larger than a prescribed threshold. CONSTITUTION:By making a band BXfa (B denotes a range of a band) of a low-pass filter 103 smaller than input frequency uncertainty UXfa, a necessary sample sample rate Na becomes small (B<N2<U), and the number of data used for a high speed Fourier-transformation (FFT) becomes small. Subsequently, in a local oscillation control circuit 107, a ratio (D1/D2) of the data maximum value D1 and a second largest value D2 at the time when the FFT is executed in the beginning is taken. In the case its ratio is larger than some threshold, it is decided that a frequency error is larger than B/2.fs and an output oscillation frequency omega of a local oscillator 101 is varied by + or -Bfa, and the FFT is executed again. In such a way, the carrier wave frequency error is estimated in a short time.

Title: Angular displacement detector
Inventor: NAKAZAWA ISAO
IPC: G03B17/00
Filed: 1989-12-01
Abstract: PURPOSE:To improve the electromagnetic efficiency and to reduce the power consumption, and to improve the environmental stability of the device and frequency characteristics by feeding a winding coil with a current which is proportional to the 2nd-order differentiated value of the relative displacement between a float body and an external cylinder. CONSTITUTION:The winding coil 7 is fed with the current which is proportional to the 2nd-order differentiated value of the difference signal between the external cylinder 2 and float 3, i.e. relative position signal (Va-Vb). Consequently, a force based upon the Fleming's left-hand rule is generated in the closed magnetic path formed of the float body 3 and a yoke 6 and this force is proportional to the current value of the coil 7, so the force which is proportional to the relative acceleration between the external cylinder 2 and float body 3 is generated. Then, when the external cylinder 2 and float body 3 are put in relative angular displacement motion, a slit image on a photodetecting element 9 moves by a quantity corresponding to the displacement. The output of the element 9 is therefore proportional to the position of the slit image and used as information to detect the angular displacement of the external cylinder 2.
