摘要： A phase locked driving type motor is reliably started and stably rotated. A motor driving device is provided with a stepper motor constituted at least of a bipolar stator, a rotor with a bipolar permanent magnet, and a driving coil magnetically coupled to the stator, a driving pulse generating means which outputs a driving pulse signal for driving the stepper motor, a driving circuit which supplies a driving current to the driving coil according to the signal from the driving pulse generating means, a voltage detecting circuit which detects the back electromotive voltage generated by the rotation of the rotor, and a magnetic pole position detecting means which detects the position of the magnetic pole of the rotating rotor with respect to the stator based on the detection signal of the voltage detecting circuit. The driving pulse generating means controls the outputting timing of the driving pulse signal based on the detection signal of the pole position detecting means used. The magnetic pole position detecting means stops the output of the driving pulse signal based on the signal detected by means of the voltage detecting circuit while the driving pulse signal is outputted and, at the same time, causes a driving pulse signal whose phase is opposite to that of the driving pulse signal to be outputted. The phase locked driving type motor is started reliably, accelerated quicky, and rotated stably. A higher-performance motor driving circuit can be realized by combining embodiments. Moreover, high-speed high-torque rotation of the motor is realized with a simple system constitution without changing the structure of a conventional flat type bipolar motor.

摘要： Water detection means (5) and actuator means for operating water depth measuring means (6) are disposed so that the water depth measuring means (6) is forcedly operated by the actuator means when the water detection means (5) detects water. A leak alarm is generated when a detected water depth below a predetermined level continues for a predetermined time even when the water detection means detects water, and the operation of the water depth measuring means is terminated. In a non-submerged mode, too, the zero-depth pressure as a reference is measured and stored in predetermined time intervals.

摘要： This invention aims at improving a method of carrying out communication between a transmission unit and a reception unit in a pulse rate meter and providing a pulse rate meter not influenced by noise. To achieve these objects, the present invention provides a pulse rate meter comprising a transmission unit provided with a detecting circuit for detecting an electrocardiographic signal obtained from a pair of electrodes fixed to the portion of a human body which is in the vicinity of the heart (2), and generating a detected signal (3), an interval data preparation circuit for counting the generation interval of the detected signals by a signal of a predetermined cycle and generating interval data (4), a serial data preparation circuit for converting the interval date into a serial signal and generating serial data signal (5), a transmission circuit for modulating the serial data signal and transmit the resultant signal as a ratio signal (6), and a battery as a power source (7), and a reception unit provided with a reception circuit for receiving the radio signal from the transmission unit, demodulating the resultant signal and generating a reception signal (8), a data decoding circuit for decoding the reception signal and generating electrocardiographic interval data (9), an operation circuit for calculating a heart rate on the basis of the electrocardiographic interval data, and a display for indicating a heart rate thereon. According to the present invention, even when the reception circuit receives noise or a signal having no relation with a heart rate, which does not constitute correct data in this case, it cannot be decoded correctly by the decoding circuit, and the data received normally in the preceding time are displayed. Therefore, erroneous heart rates are not displayed.
