Title: Alternating system of reference station for tdma satellite communication system
Inventor: SABURI AKIO
IPC: H04B7/15
Filed: 1984-05-10
Abstract: PURPOSE:To attain an alternating system of reference station which can be applied concentrically by selecting one of earth stations as a spare reference station excluding the reference station to transmit a synchronizing burst that can be easily discriminated from those of other earth stations and at the same time securing a function that transmits a spare reference burst which can substitute the function of a reference burst when no reference burst is transmitted. CONSTITUTION:A spare reference station discontinues the burst synchronization that is so far carried out subordination to a reference burst in case the reference burst is lost and the prescribed conditions are satisfied. Then the spare reference station transmits the burst of own station with the timing of its own. Thus a spare reference burst is transmitted only when a fact is confirmed that at least one of synchronizing bursts of stations exculding the reference station and own station is received normally.

Abstract: PURPOSE: To enable to shorten the time turned from ignition to stable combustion and to suppress the generation of the incomplete combustion constituent by a method wherein a preheating means is provided along the peripheral part of an evaporation element in the liquid fuel combustion equipment for house heating.  
     CONSTITUTION: The fuel is supplied to the evaporation wick 2 induced upward through an induction wick 1. The air, which is flowed from a suction port 14 to a louver 13 by means of a blower 12, causes the static pressure within a combustion chamber 10 negative, resulting the air in leading from an inner and an outer flame tubes 3 and 4 through an evaporation chamber 5 to the combustion chamber 10. In order to ignite, at first the peripheral part of the evaporation element is preheated by supplying the electricity to a heater 18 and an ignition torch is brought close to the evaporation element until the combustion starts. Because the fuel gas evaporated by the preheating mixes with the air within the combustion chamber 10 to start the combustion immediately and the heat of combustion is transmitted to the evaporation element 2, the time to turn to the stable combustion can be shortened and the incomplete combustion at the time of ignition can be suppressed.

Filed: 1989-04-15
Abstract: PURPOSE:To enable A/D conversion with the small number of bits, improve noise resistance and ensure a wide dynamic range by over-sampling A/D conversion several times larger than a signal range via a differential A/D conversion means. CONSTITUTION:A clutter component is eliminated from LPFs 9a and 9b in BPF and a doppler displacement signal is thereby obtained. Furthermore, a difference between data from LPFs 9a and 9b and an analog signal from DAC 25 is amplified, and the differential data is over-sampled in ADC 22. In addition, the differential data entered in ADD 23 is added in turn to a value preliminarily saved in LATCH 24, and absolute signals are outputted to the LATCH 24 and FFT 12. According to the aforesaid construction, a clutter component is substantially reduced due to the over-sampling and A/D conversion becomes possible with the small number of bits. Also, a wide dynamic range can be embodied and a white noise level is equivalently reduced considerably for a widened range. Consequently, noise resistance quality can be improved.
