摘要： PURPOSE:To enable use of an auto-calendar beyond a year setting range by providing a year limit detecting circuit, a day-of-the-week counter, a day-of- the-week switching circuit, etc. CONSTITUTION:A year counter 601 receives a one-year signal Py from a month counter 62 as an input through an AND gate 603 and outputs year information Dy. Counting thereof is 90 to 00 and 00 expresses that a range wherein a year can be set is exceeded. A year limit detecting circuit 602 detects 00 from the information Dy and outputs a day-of-the-week switching signal Pw. A gate 603 outputs the signal Py when the input of the signal Pw is absent, while it stops the output when this input is present. A day-of-the-week counter 605 receives a one-day signal Pd as an input, counts a day of the week and generates day-of-the-week counter information Dcw, while it stops counting and fixes the information Dcw at 6 when the signal Pw is not inputted. A day-of-the-week switching circuit 606, which outputs day-of-the-week calculation information Dmw from a day-of-the-week calculating circuit 64, makes switching over to the information Dcw sent from the counter 605 and outputs it when the signal Pw is inputted. In this way, display of a month, a day and the day- of-the week can be used even when a year setting range is exceeded.

摘要： PURPOSE:To always measure a fixed value by constituting a reference voltage generating circuit out of a single constant voltage power source and a resistive division for dividing an output voltage of the constant voltage power source. CONSTITUTION:An output Ss of a sensor 1 is amplified 3 and supplied as an amplified voltage Vs to an A/D converter circuit 4. At that time, the detecting sensitivity of the sensor 1 is proportionate to the value of a sensor driving signal Sd supplied from a sensor driving circuit 2. Now, the reference voltage generating circuit 5 is constitutive of the constant voltage power source 52 and its common voltage Vc divided by resistors 54-56 with their resistance values R1-R3 respectively. In this circuit 5, if the resistors 54-56 have entirely equal temperature and electric characteristics, their resistance values R1-R3 are varied as equally as well. That is, when the voltage Vc is varied by beta% due to variations of the temperature and/or the power source voltage, etc., a sensor driving voltage Vd and an integrated reference voltage Vi, which are generated by the resistive division of the voltage Vc, are also varied by beta%. Now, since the voltage Vs is denotive of Vs=l.Vd (l=AXPXk; A:- an amplification factor for the circuit 3, P:- detecting amt. and k:- a proportional constant), if a voltage Vd is varied by beta%, the voltage Vs is also varied by beta%, so that an A/D converting value is never varied at all.

摘要： PURPOSE:To increase max. set time and to improve resolving power just before the termination of a timer by selectively using an ordinary mode by a timer unit signal and an enlarged display mode by a high speed timer unit signal. CONSTITUTION:A 59 detecting circuit 19 detects that the content of a 60min counter 8e is 59 and said circuit outputs a second mode signal Pmm when the content of the counter 8e attains 59 and when a pointer 2a indicates a 59 step, i.e., the position of the remaining one minute. Then a correction circuit 14 outputs a correction pulse Phe and supplies the same to a driver 16. On the other hand, a change-over circuit 3 is changed over to the state of selecting a terminal B to output the second signal Ps which is the high-speed timer unit signal supplied to the terminal B and supplies said signal to the driver 16. The driver 16 drives the pointer 2a by supplying the motor driving signal P4 of one second period synchronized with the second signal Ps to a motor M2.
