Title: Array antenna system
Inventor: SUZUKI IKUO
IPC: G01S7/02
Filed: 1985-03-29
Abstract: PURPOSE:To eliminate deterioration of a radiation pattern due to temperature change and frequency fluctuation by dividing a phase proportional to square of the distance from the center of an array antenna to a radiator by a minimum phase shift amount of a digital phase shifter and using the remainder of the division as the relative delay phase of a feeder reaching each radiator. CONSTITUTION:The phase proportional to square of the distance from the center of the array antenna comprising plural radiators 1I-1N to the radiators is divided by the minimum phase shift amount of the digital phase shifters 3I-3N and the remainder of the division is used as the relative delay phase of the feeders 2I-2N, 4I-4N reaching the radiators 1I-1N. Thus, the deterioration in the radiation pattern due to temperature change and frequency fluctuation is reduced remarkably and then a phased array antenna not requiring any air-conditioner is realized. Further, when the operating frequency range is narrow comparatively, a phased array antenna not requiring feeder delay phase correction of different configuration at each channel is realized.

Title: Cassette type tape recorder
Inventor: IWATA MITSUO
IPC: G11B15/675
Filed: 1978-05-29
Abstract: PURPOSE:To achieve the improvement in operating characteristic and prevent the deformation, etc. of a pinch roller by moving a cassette from the upper non-performance position to lower performance position through the utilization of the driving power of a motor at the mounting of the cassette and accumulating energy in a spring. CONSTITUTION:At the mounting of a cassette, the cassette is automatically moved from the upper non-performance position to lower performance position through the utilization of the driving power of a tape-driving motor 44. At the time when a sliding member 25 slides rightward during this movement, energy is accumulated in a spring 26 and the performance state is maintained by making use of the attraction force of an electromagnet. To reset the cassette to the non-performance position, the attraction force of the electromagnet is released, then the energy having been accumulated in the spring 26 resets the sliding member 25. Even when a power switch is turned off in the performance state, the attraction force of the electromagnet will be lost and therefore the cassette may be automatically reset to the non- performance position by the accumulated energy of the spring 26. Thus, damaging of the pinch roller, etc. is prevented.

Abstract: PURPOSE:To avoid the accumulation of a phase error by adding a prescribed phase difference sequentially between sampling points to an initial phase, obtaining a phase of a subcarrier at each sample point and converting the phase into an amplitude of a sinusoidal wave signal and a cosine signal.

Thus, the accumulation of the phase error by multiplication of sin and cos values is avoided.
