Filed: 1987-12-18
Abstract: PURPOSE:To realize an earth sensor which can respond to a spin phase and non-spin phase, by providing a means to fix a reflecting surface of a reflector on a light receiving shaft of an infrared detector. CONSTITUTION:A rotating shaft 5 of a reflector 3 and an infrared detector 6 are fixed on a satellite in a fixed position relationship. In a non-spin phase, infrared rays 2 radiated from the earth 1 are reflected with the reflector 3 turning on the rotating shaft and incident into the infrared detector 6 to detect an earth code range.

Title: Magnetic recording method and recording and reproducing device
Inventor: AMADA NOBUTAKA
IPC: H04N5/782
Filed: 1989-12-13
Abstract: PURPOSE:To satisfactorily reproduce video or audio signals by setting a bias frequency to specified times the carrier frequency of a digital sound signal and preventing the fifth order distorsion component from being reproduced cross modulation the bias signal and digital sound signal. CONSTITUTION:The audio signals recorded to the deep magnetic layer part of a magnetic tape 50 are reproduced by magnetic heads 52a and 52b for sound, amplified 26 through a switching circuit 25 and afterwards supplied to BPF 27a and 27b and equalizer 35. In such a case, the BPF 27a generates the audio signal of a left channel, to which FM modulation is executed by the carrier of 1.3MHz, and outputs it from a terminal 29a. In such a case, the BPF 27b takes out the audio signal of a right channel, to which FM modulation is executed by 1.7MHz, executes FM demodulation to the audio signal and outputs it from a terminal 29b. On the other hand, the equalizer 35 amplifies a high area component, which is attenuated by erasing the overwrite of the video signal, corrects a frequency property and outputs the signal through a BPF 36. Since the frequency of the bias signal is made four times the carrier frequency of the digital audio signal, interference caused by the fifth distortion component is canceled.
