摘要： PURPOSE:To shorten a lock-up time as much as possible and to perform FSK modulation to the oscillation frequency of a VCO directly with code strings by varying the signal transmission characteristics of an LPF at the time of lock-up and transmission. CONSTITUTION:For a reception operation, the radio waves of 429.75MHz, inputted to an antenna 1 are amplified through a transmission/reception switching means 2 in a high-frequency amplifier means 3 and then converted to 450kHz of an intermediate frequency in a frequency conversion means 4. Then, FSK demodulation is performed by a detection means 6. The signals of the VCO 8 are 34344-frequency-divided by a frequency divider means 9 and the reference signals of 12.5kHz are outputted at a reference frequency oscillation means 10. The phases of the 12.5kHz reference signals and the 34344-frequency-divided signals from the means 9 are compared and a phase difference is outputted in a phase comparator means 11 and the high-frequency components of the 12.5kHz signals are removed in the LPF 15. Then, the VCO 8 is controlled so as to make the phase difference '0' and the oscillation frequency is turned to 12.5kHzX34344=429.3MHz. The frequency dividing number 34344 of the frequency divider means 9 is set by the signals from a control means 16.

摘要： PURPOSE:To receive a signal of large frequency shift or a signal of high code change speed to reproduce the code string of transmission data without error. CONSTITUTION:A phase difference detecting means 11 which detects the phase difference between signals from first and second mixing means 3 and 8 and a frequency correcting means 15 which detects the difference between a carrier signal frequency to be received and the signal frequency from an oscillating means 6 and controls the oscillation frequency of the oscillating means 6 in the frequency error eliminating direction are provided. A multiplying means 16 is provided which multiplies the signal by the signal of a pulse signal generating means 18 which generates a pulse signal from the signal of the phase difference detecting means 11 synchronously with a bit synchronizing signal. Thus, an angular frequency error (x) between the carrier frequency to be received and the oscillation frequency of the oscillating means 6 is corrected, and the code change speed is reduced to accurately reproduce a code string p(t).

摘要： PURPOSE:To exactly estimate the working condition of each gas appliance even with accumulation of water on a measuring diaphragm and resulting change in measuring a flowrate by correcting stored ignition flowrate information when a change in state from non-use of gas to use of gas is estimated. CONSTITUTION:A flowrate conversion part 11 calculates flowrate from the frequency measured with a flowrate measuring means 9 using a conversion factor and stores it in a storage part 13. A change judgment part 14 compares the present flowrate with the previous flowrate in the storage part 13 and calculates the flowrate change when it is larger than a predetermined threshold. An appliance information storage means 16 stores an ignition flowrate of a gas appliance in advance. An individual flowrate estimation part 17 estimates the working conditions of each gas appliance from the flowrate change of the judgment part 14 and ignition flowrate information stored in the storage means 16. An ignition flowrate comparator 20 compares the ignition flowrate information stored in the storage means 16 with the flowrate change of the judgment part 14 and calculates a corrected ignition flowrate when use of gas is estimated by the estimation part 17 and renews the ignition flowrate in the storage means 16 with the corrected ignition flowrate.

摘要： PURPOSE:To surely estimate in which apparatus a flow rate changes concerning a flow rate change when the gas apparatus is turned on and immediately adjusted to have the appropriate flow rate. CONSTITUTION:This flow rate change estimating device is constituted of a flow rate measuring means 1, a storing means 3 storing a signal from the means 1 at every certain time, a change presence or absence judging means 4 inputting the signal from the means 1 and the signal from the means 3 and judging the presence or absence of the flow rate change through the use of a past flow rate value stored in the means 3 and the present flow rate value from the means 1 so as to output it, a change history storing means 9 storing the history of the change flow rate by the signal from the means 4 and an individual flow rate estimating means 5 estimating from what phenomenon the flow rate judged by the means 4 is generated through the signal from the means 4 and the signal from the means 9. When the turned on gas apparatus is immediately adjusted to have the certain flow rate, it is judged that the flow rate change is the change immediately before and there is high possibility in the change of the gas apparatus so that the largeness of possibility is compensated and it is estimated in which gas apparatus the flow rate changes.

摘要： PURPOSE:To obtain a flow rate detector which detects a series of continuous flow rate change of one gas apparatus as one same flow rate change accurately. CONSTITUTION:A title item consists of a memory means 3 which stores a signal from a flow rate measuring means 1 at every certain time and a same change criterion means 8 which allows a signal from the flow rate measuring means 1 and the memory means 3 to be input, compares a past flow rate value which is stored in the memory means 3 with a current flow rate value from the flow rate measuring means 1, and then judges whether the current flow rate change is halfway through a series of continuous change of a gas apparatus or a series of flow rate change is completed, thus enabling even a gradual change of the flow rate of a certain gas apparatus over two or more unit times to be detected as one or more continuous flow rate change accurately and then preventing the flow rate change of one apparatus from being detected erroneously as the flow rate change of two or more apparatuses.

摘要： PURPOSE:To obtain an economical battery power supply, which ensures an average current consumption conformable to each operation mode, by a constitution wherein power is fed from a first battery section to a first load section for controlling a switching section and power is fed from first and second battery section connected in series to at least a second load section. CONSTITUTION:During low current operation with a first predetermined voltage of low level, only a first load section functions to feed power only from a first battery section. When a switching section is controlled by the first load section, power is fed from first and second battery sections, connected in series through a second voltage control section, to a second load section which operates with a second predetermined voltage higher than the first predetermined voltage. According to the constitution, the second battery section is only required to ensure the average current consumption of the second load section although the first battery section is required to ensure the sum of average current consumption at first and second load sections.

摘要： PURPOSE:To omit safety check by man by measuring automatically the gas flow rate of the gas passing through gas supply facilities on the side upstream of a gas meter which constitutes the gas supply facilities and judging that there is a gas leakage if gas flow rate exists continuously for a certain time. CONSTITUTION:The signal from a flow rate sensor 8 is inputted to a comparator 9. The comparator 9 outputs signal when the signal from the flow rate sensor 8 is over a certain level. a timer means 10 starts measuring time by the signal from the comparator 9, and outputs signal after, for instance, 30 days. A judgement means 11 monitors the signal of the comparator 9 for 30 days after starting the time measurement by the timer means 10, and if output is generated from the comparator 9 continuously for 30 days the judgement means 11 judges that there is a gas leakage from the gas supply facilities and signal is sent to an output means 12. The output means 12 which is informed of abnormality informs men of the abnormality and sends alarm to the control center. Or a gas shut-off valve provided in the gas supply facilities is operated and the gas supply is stopped.
