摘要： An electronic apparatus with a vibration informing function comprises a vibrating device capable of vibrating for providing information. A reference signal generation circuit outputs a reference signal for producing an operation timing signal. A vibration control device judges whether to vibrate the vibration device and outputs a vibration alarm ON signal in synchronism with the reference signal output by the reference signal generating circuit when it is judged to vibrate the vibration device. A vibrating device control circuit stores predetermined intermittent driving patterns and outputs one of the predetermined intermittent driving patterns in synchronism with the reference signal output by the reference signal generating circuit when the vibration alarm ON signal output by the vibration control device is input thereto. A vibrating device driving circuit outputs a driving signal for vibrating the vibrating device intermittently in response to the predetermined intermittent pattern output by the vibrating device control circuit.

摘要： A highly reliable optical communications equipment is offered, which can control light more accurately than heretofore (i.e., less restrictions are imposed on the amount of attenuation and on the resolution) and which is equipped with a latching function. The optical communications equipment includes a piezoelectric actuator, a moving body moved by the piezoelectric actuator as a drive source, a multi-coating filter for controlling light that is a signal medium by movement of the moving body, a drive circuit for controlling the position of the multi-coating filter via the actuator, and a control circuit. The piezoelectric actuator uses bending vibrations produced in a piezoelectric vibrating body as a power source. If the moving body is not moved for a given time, the control circuit sends a function keeping signal to drive the actuator to such an extent that the moving body does not move. Thus, the function of the actuator is maintained.

摘要： In a self-excited oscillator circuit, a buffer is connected to an electrode or electrodes, and a buffer and an inverter are connected to an electrode or electrodes. Each of the inverters and and the buffer has a tri-state configuration and is capable of setting an output terminal in a high-impedance state, i.e., turning off an output signal, according to a signal input to a control terminal. Therefore, it is possible to turn off a drive circuit and the ultrasonic motor by setting the inverter in the high-impedance state. It is also possible to change the direction of movement of the moving member by setting one of the buffer and the inverter in the high-impedance state.

A moving body is disposed in contact with the vibrating body and is driven in response to oscillation of the vibrating body. A control signal generating circuit outputs to the self-excited oscillation circuit a drive command signal or a stop command signal to bring the self-excited oscillation circuit into a drive state to drive the moving body or a stop state, respectively. The control signal generating circuit is set so that a length of the drive command signal is a time period required for the self-excited oscillation circuit to start oscillating at a frequency corresponding to a given frequency for driving the moving body.
