Abstract

PURPOSE:To obtain an inexpensive and small long-term timer, by electrically detecting the abrupt voltage drop of a battery by setting the dry battery such as a silver oxide battery having a flat discharge curve to a time standard to perform an alarm or display. CONSTITUTION:A dry battery 1a is discharged through a resistor 1b. At first, a variable resistor 2c is regulated and a transistor 2b is set to an OFF-state. When the elapse of a time comes to To in a drawing, the voltage of the dry battery 1a is abruptly dropped and, therefore, the transistor 2b is turned ON and a transistor 2a is also turned ON to emit an alarm or to perform display by an alarm or display device 3b. The value of a capacitor or resistor 2d is selected so as not to generate voltage drop before a power source 3a comes to To. Because the discharge characteristics of the dry battery are used as a time standard as mentioned above, a timer used in a range from several months to several years can be easily realized.

Timers can be broadly classified into electronic or mechanical devices, as shown in FIGS. 3 and 4. The electronic type shown in FIG. 3 will be explained. In the oscillation circuit 4, crystal or CR
etc. to generate an original oscillation, a frequency divider circuit 5 divides the frequency according to a desired period, and a drive circuit 6 operates the display section 7 according to the output from the frequency divider circuit 5. 8 is N source. Reference numeral 13 denotes a control circuit, which is composed of a switching circuit and the like so as to change the number of frequency division stages of the frequency dividing circuit 5. For example, for a long timer such as about six months, set 32 to one.
Although it is possible to configure it with chipLSI, it is not only used for general purposes, so it is expensive as well as the IC development cost. Furthermore, if a generally available IC configuration is used, the configuration is made up of several ICs, which has the disadvantage of not only being large in size but also expensive. The mechanical type shown in FIG. 4 will be explained. Power supply (AC)
12, the synchronous motor 9 rotates in synchronization with the frequency of the power supply. For example, if the rotational speed at the same time is krprA, then for the timer setting period about half a year later, the reduction ratio 7, which is decelerated by the gear train 10, will have the last gear for setting half a turn. (not shown)
Assuming that the switch is ON or 0FFL, then. However, one month has 31 days. Further, in order to change the set time, the timer can be set by moving the switch relatively according to the value. The display section 11 shows these. As mentioned above, the mechanical type requires AC power to operate the motor, so it lacks portability. Also, since it requires a synchronous motor, it becomes heavy and large. ■Mold costs for gears, etc. are high. ■The width of the set time (period) is restricted. It has the following drawbacks.

In the present invention, a dry battery such as a silver oxide battery having a flat discharge curve is used as a time reference. The battery capacity is C[Ah (ampere hour), the load is R[
Ω], and the battery voltage is V [Volt], then the time f-1 [Hrs] during which the battery voltage suddenly drops can be found as follows. < 1 = -! -> Using this as a time reference, a sudden drop in battery voltage is electrically detected and an alarm is issued or displayed. .

3a is a power source, and 3b is an alarm or indicator. The dry battery 1a is discharged through the resistor 1b. FIG. 2 shows the discharge characteristics of the dry battery 1a. variable resistance 2c
is adjusted to set the transistor 2b to the OFF state. As time passes, the voltage of the dry battery 1a, that is, the terminal voltage of the resistor 1b, suddenly drops when reaching To in Fig. 2, so that the voltage of the transistor 1-transistor 2b is ONL, and the transistor t)
2a: bON, and an alarm is issued or displayed on the alarm device or display 3b. The value of the capacitor or resistor 2d is selected so that the voltage of the power supply 3a does not drop before 1. Specifically, the time axis generating section 1 will be explained. Assuming the initial voltage Eo of the dry battery, the capacity C, the forward voltage drop V of the diode, and the resistance value R of the resistor 1b, the voltage drop time is as follows: Substituting specific values, C=140X10 [Ah] R=100X103 [Ω] Eo = 1, 3 [Volt] Vf = 0.6 [Volt] By selecting the value of pR or the value of C, To can be easily varied widely by 1.
