摘要： PROBLEM TO BE SOLVED: To provide a meter controller capable of shortening the times of second clock oscillation and of estimating the oscillation time.
SOLUTION: The meter controller is provided with a reference clock oscillator which generates a reference clock for measuring the time, has a means 12 of forming and terminating the second clock which is a multiple of the reference clock frequency, and measures a specified time from the variation of an external input. The controller initiates the first oscillation of the second clock, synchronized with the variation of the external input; terminates the first oscillation of the second clock synchronization with the first on-state of the reference clock; measures with the reference clock, the time from the first oscillation termination of the second clock to the moment of the second on-state of the reference clock, before the lapse of a specified time, and initiates the second oscillation of the second clock synchronized with the second on-state of the reference clock.

摘要： PROBLEM TO BE SOLVED: To provide a resources usage measuring device and a control circuit thereof capable of inhibiting degradation of nonvolatile memories to enhance reliability of data storage. SOLUTION: When flow rate variation ΔQ of gas is measured more than the smallest accounting unit of 1 m 3 (step S102; N), writing period WP is set up at a usual writing period WP1 (step S103); whereas when ΔQ is measured less than 1 m 3 (step S102; Y), writing period WP is set up at a writing frequency WP2 that is reduced from the usual writing period WP1 (step S104). Thus, nonvolatile memories can be protected from degradation, resulting from meaningless iteration of writing despite of no variation in flow-rate integrated value, as conventionally. Based on conditions of batteries, for example, the output voltage between terminals or the period of use (calendar year), and the like, by controlling to enhance writing period during the end of the lifetime of a battery, reliability is enhanced in data storage.

解决方案：当测量气体的流量变化ΔQ大于1m 3 的最小计费单元（步骤S102; N）时，写入周期WP以通常的写入周期WP1 （步骤S103）; 而当ΔQ被测量小于1m（步骤S102; Y）时，写入周期WP以从通常写入周期WP1减小的写入频率WP2建立（步骤S104）。因此，如传统上那样，不管流速积分值没有变化，非易失性存储器都可以免受降级的影响，这是由于无意义的写入迭代。基于电池的条件，例如，终端之间的输出电压或使用期限（日历年）等通过控制以提高电池寿命期间的写入周期，在数据存储中提高了可靠性。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a flow rate measuring device for automatically and accurately detecting in a simple way occurrence of pulsation or mix of noises without unnecessarily increasing power consumption. SOLUTION: When a variation ▵Q per unit time of an instantaneous flow rate is a preset value or more (Step S101: Y), a pressure sensor measures pressure, and when the fact that a variation ▵P per unit time of the pressure is a preset value or more (Step S102:Y) is continued over a preset sampling frequency (Step S104:Y), the occurrence of pulsation in gas is determined (Step S105). In this case, the pressure of the gas is measured at a frequency higher than the preset sampling frequency for a preset time by the pressure sensor and information for its measurement result is recorded or output. When the occurrence of the pulsation in the gas is determined over the preset frequency, an alarm part issues an alarm. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To avoid the problem on security that applying becomes poor and going out etc. are generated when a customer starts using gas, because zero point shift is detectable in the state that flow rate zero is surely output in the state of closed valve, a pressure value is taken in at an interval finer than usual, the fall off is monitored, and the valve is opened in the case of fall off.

When the average flow rate is in a first threshold value range of leakage judgement, and difference between the maximum flow rate and the minimum flow rate is in a second threshold value range which can be considered to be sufficiently stable, the control circuit part determines that zero point abnormality is not present, where m is a constant larger than or equal to 1.

摘要： PROBLEM TO BE SOLVED: To provide amount measuring equipment of resources used wherein the reliability of data storage can be improved by preventing the deterioration of an EEPROM, and its control circuit. SOLUTION: When flow rate variation ΔQ of gas is judged as at least 1 m 3 which is charging minimum unit (step S102;N), write-in frequency WP is set as a normal write-in frequency WP1 (step S103). When flow rate variation ΔQ of gas is judged as at most 1 m 3 (step S102;Y), write-in frequency is set as write-in frequency WP2 which is smaller than the normal write-in frequency WP1 (step S104). Deterioration of the EEPROM can be prevented which is to be caused by the repetition of futile writing although there is no variation in flow rate integral like before. On the basis of condition of a battery, e.g. on the basis of an output voltage between terminals, usable years (calendar years), etc., control is performed which increases write-in frequency in lifetime last stage of the battery, and the reliability of data storage is improved.
