摘要： PURPOSE:To compute the residual amount of a battery by taking its temperature into consideration. CONSTITUTION:The temperature of a battery 1 is measured by a temperature sensor 7. Temperature information is converted into a digital signal by a temperature-information intake part 9. A battery residual capacity factor K2(T) and a power consumption factor K1(T) are computed by a factor compensation part 11 for integration. A voltage-to-current conversion part 15 computes a current value, flowing in a resistance 5, on the basis of the measured value of a voltmeter 13, and an analog-to-digital conversion part 17 converts the current value into a digital signal id. An integration calculation part 19 computes a battery residual amount X on the basis of the digital information id about the current value sent from the analog-to-digital conversion part 17, the battery residual capacity factor K2(T) sent from the factor computation part 11 for integration and the power-consumption factor K1(T).

摘要： PURPOSE:To eliminate the need to gather data by a person at the automatic vending machine and to gather the data in an optional time zone by receiving management information by a telephone-set side radio transmitter receiver and sending it to a management center side through a public telephone line. CONSTITUTION:On the side of the management center 1, the telephone-set side radio transmitter receiver 8 is actuated through the public telephone line 4 on the basis of a discrimination number given to each automatic vending machine 9 to sends an actuation signal to a single or plural automatic-vending-machine side radio transmitter receivers 10. A spread spectrum system is employed as a data modulation system between radio transmission and reception. Consequently, a signal is sent from the side of the management center 1 to the telephone-set side ratio transmitter receiver 8 through the telephone line, i.e., on a wire basis so as to obtain the information of the automatic vending machine 9. Then a radio communication is made between this telephone-set side radio transmitter receiver 8 and automatic-vending-machine side radio transmitter receivers 10... and the data of the sides of the automatic vending machines 9... are inputted to the management center 1 through the automatic-vending- machine side radio transmitter receivers 10..., the telephone-set side radio transmitter receiver 8, and the telephone line 4.

摘要： PROBLEM TO BE SOLVED: To provide a gas meter that can surely execute a safety operation. SOLUTION: A control unit 15 measures a temperature T of gas G using a temperature sensor 11 mounted on a meter itself, an installation environment for a gas meter 10 is judged to be brought into a dangerous high-temperature environment in use of the gas G, for example, because of generation of abnormality such as a fire disaster, when the temperature T comes to an upper limit temperature TM (for example, TM=70°C) or more (T≥TM), and the safety operation is executed therein. An abnormality such as fire disaster is detected by the control unit 15 autonomously, different from a conventional gas meter in which an equipment (for example, an automatic fire alarm) for detecting the abnormality in the installation environment is arranged separately from the gas meter 10, and in which the operation for the safety is executed in response to notification by the external equipment, and the operation for the safety is executed by the judgement of the control unit itself. A problem that the gas meter 10 is brought into the condition where the operation for the safety gets execution-incapable caused by a trouble in the automatic fire alarm and communication disturbance can be evaded thereby.

摘要： PROBLEM TO BE SOLVED: To accurately display an integrated amount of gas consumption by, with a simple configuration, instantaneously judging occurrence of pulsation in the rate of flow, which is to be measured, and excluding effect of the pulsation through a passing flow-rate calculation. SOLUTION: A micro heater 53 is provided in a flow path where a fluid flows. At least two pairs of temperature sensors are provided which comprise two thermo piles 55, 57, 59a and 59b respectively arranged in symmetry on the upper stream side and the lower stream side of the micro heater 53. Related to the thermo piles 55, 57, 59a and 69b, the pairs are arranged by different distance from the heater, respectively, and the difference in voltage between the temperature sensors at different distances is used as a base for detecting presence of the pulsation in the fluid.

摘要： PROBLEM TO BE SOLVED: To provide a fluid flow rate measuring device capable of obtaining desired stream lining effect by a mesh as suppressing a pressure loss. SOLUTION: In a gas meter 1 interposed halfway on a gas piping connected to a gas supply source at its upstream side and to a gas consuming source at its down stream side, the flow speed of gas is measured by using a microprocessor sensor 5 provided at the downstream side of the corner 3a of a passage 3. When finding the flow of the gas passing 3 through the passage 3 by a microcomputer 13 by multiplying it by the cross section of the passage, the stream lining effect required to uniform the flow speed distribution of the gas reaching three spots of the passage in each of which the microprocessor sensor 5 is provided can not be singly obtained between the corner 3a and the three spots of the passage where the microprocessor sensors 5 are provided. Therefore, a coarse mesh 17 and a relatively fine mesh 19 are disposed.
