摘要： PURPOSE:To secure the indication of traveling direction, by showing deviation from the direction on a display member, starting at the time when a set timing signal is generated. CONSTITUTION:In response to a set timing signal Pt from a switching circuit 12, a latch circuit 13 outputs intact a bearing data Dh inputted to a terminal D from a terminal Q as traveling direction data Da. A subtraction circuit 14 subtracts the data Da inputted to a terminal I2 from the data Dh inputted to a terminal I1 and outputs it as deviation data Dr. When the subtraction value is negative, a value obtained by addition of 60 thereto is outputted as deviation data Dr. A decoder driver 15 receives the input of the data Dr and outputs a deviation display Dr to perform a lighting for the direction of deviation among deviation display segments of a display panel 7. This display facilitates the correction of traveling direction thereby enabling the indication of a correct traveling direction accurately.

摘要： PURPOSE:To make the movement of a display segment follow up that of a bearing indicator by controlling a timing signal generating circuit by the output signals from a data stabilization detecting circuit and changing over the period of timing signals. CONSTITUTION:Since, when a bearing indicator is displaced from a condition wherein low speed timing signals P12 supplied to the terminal B of the selector circuit 11b of timing signal generating circuit 11 are changed over to be supplied to a driving circuit 2, the level of the sensor output signals Ps is changed which are the output of a geomagnetic sensor 3, the output of a calculating circuit 5, or bearing data Dh are also changed and different data from the former ones are recorded in the memory circuit 10a of a data stabilization detecting circuit 10. Thus, a continuous data detecting circuit 10b stops to generate continuous detecting signals Pc and, by changing over and supply timing signals Pt1 to the driving circuit 2, the selector circuit 11b of the timing signal generating circuit 11 resumes a drive of a 4Hz period.

摘要： PURPOSE:To decrease the test time while keeping the current consumption low at the normal state by providing a power changeover circuit supplying switchingly a low voltage and a power voltage from a regulator circuit to a part of an oscillation circuit and a frequency division circuit and bringing the level of the voltage fed to the part of the oscillation circuit and the frequency division circuit as a power voltage. CONSTITUTION:Since the level of a T terminal 20 is normally at L and the level of a terminal C of a power changeover circuit 22 is at H via an inverter 23, a Vreg voltage fed to a terminal A is outputted from a terminal O of the power changeover circuit 22 and the oscillation circuit 4 and the frequency division circuit 5 are brought into a low voltage. In bringing the level of the T terminal 20 by external operation at the logic test to H, the level of the terminal C of the circuit 22 is at L via the inverter 23. Thus, a voltage VSS fed to a terminal B is outputted from the terminal O of the power changeover circuit 22, the oscillation circuit 4 and the frequency division circuit 5 are driven by the voltage VSS being a power voltage, and the highest operating frequency of the oscillation circuit 4 and the frequency division circuit 5 is increased.

摘要： PROBLEM TO BE SOLVED: To drive an electromagnetic conversion means without affecting a hand driving motor in an electronic timepiece provided with the electronic conversion means generating electromagnetic noise as a vibration motor.
SOLUTION: At the time of starting drive of the electromagnetic conversion means, whether a timepice motor is in driving or not is determined. When the motor is in driving, drive of the electromagnetic conversion means is waited until the drive of the timepiece motor is ended, and after ending the drive of the motor, the drive of the electromagnetic conversion motor is started. Rotation/non-rotation detection of the motor is prohibited during the drive of the electromagnetic conversion means, and the drive is performed at a compensation pulse never affected by magnetic field, whereby the motor can be further surely driven.

摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to improve resolution per unit pressure since a dynamic level cannot be effectively used when a variation in the sensitivity and offset of a sensor is considered, and the amplification factor of an amplification circuit needs to be reset to the characteristics of the sensor when using the sensor having different specifications. SOLUTION: A sensor characteristic expression is determined based on two memory data stored at first and second memories by a process for adjusting an offset voltage value by inputting an offset increase/decrease pattern while a first pressure is being applied to the sensor, a process for adjusting an amplification factor by inputting an amplification factor increase/decrease pattern while the second pressure is being applied to the sensor, a process for storing conversion data that are outputted from an A/D conversion circuit in the first memory while the first pressure is being applied to the sensor, and a process for storing conversion data that are outputted from the A/D conversion circuit in the second memory while the second pressure is being applied to the sensor.
