摘要： PROBLEM TO BE SOLVED: To provide a decoder circuit, along with a node comprising the decoder circuit, capable of decoding the serial data having been encoded with a binary code, with no use of a clock signal.SOLUTION: An edge detection circuit 10 detects an edge of a serial signal SI. A timing signal generating circuit 21 generates a timing signal ST of which a signal level rises according to lapse of time after edge detection. By comparing a signal level of the timing signal ST with reference voltages Vrefi(i=2-6), determination signals J2-J5 and a standby state signal JW are generated. A bit conversion circuit 30 determines how many fold of unit time (number of bit) corresponds to an edge interval based on the signals J2-J5 and JW, and repeats, every time an edge is detected, the operation of sequentially writing a set bit value representing signal level of serial signal SI at the edge interval which is to be determined into a reception register by the number of bits of the determination result, for generating a bit train provided by decoding the serial signal SI.

摘要： PROBLEM TO BE SOLVED: To reduce noise generated from a piezo actuator drive device.SOLUTION: In a piezo actuator drive device 1, during execution of charge/discharge control by a charge/discharge control unit 17, when a current detection unit 16 is detecting a piezo current, a noise propagation prevention switch control unit 19 turns on a noise propagation prevention switch 18 and when the current detection unit 16 is not detecting a piezo current, the noise propagation prevention switch control unit 19 turns off the noise propagation prevention switch 18.

摘要： PROBLEM TO BE SOLVED: To control the rate of change in discharge energy of piezo actuator (hereinafter referred to as piezo) at a desired fixed value. SOLUTION: In a driving unit of the piezo 1, the piezo 1 is discharged by repeating such an operation that a discharge switch 10 is turned on until a discharge current of the piezo 1 becomes a peak-side threshold Ip if a drive signal becomes low, and the switch 10 is turned on again if the discharge current decreases to a bottom-side threshold Ib when the switch 10 is turned off. In this case, a threshold setting circuit 20 is provided which raises the peak-side threshold Ip in proportion to a time duration. The threshold setting circuit 20 receives values such as a charging energy E0 charged in the piezo 1, a discharge energy ΔE to be discharged from the piezo 1 and a discharging time T and a bottom-side threshold Ib. Based on each of the values and the charge potential amount Q0 detected at the time of charging the piezo 1, a slope and an intercept of Ip for setting the change rate of discharge energy as "ΔE/T" are determined, and the Ip is set based on the slope, the intercept and the elapsed time t from the start of discharge.

摘要： PROBLEM TO BE SOLVED: To accurately detect the rotational state of a DC motor, without preparing a sensor, such as an encoder.SOLUTION: A motor 2 has a configuration in which a capacitor C1 is connected, in parallel with a first phase coil L1 out of the first phase coil L1, a second phase coil L2 and a third phase coil L3. The configuration alters the impedance of the motor circuit in two steps at each 180 degree rotation of a rotor. A control section 6 drives the motor 2 by using the PWM control. In other words, a current flowing the motor 2 pulsates according to ON-OFF switching of a drive switch MOS by the PWM control. The PWM control results in that the motor current has AC components. Additionally, the amplitudes of the AC components change according to the change of the impedance of the motor circuit following the rotation of the rotor. Here, the control section 6 detects the rotational angle and the rotational speed of the motor 2, based on the amplitude change of the AC components.

摘要： PROBLEM TO BE SOLVED: To prevent variation of an expansion rate of piezo-actuators due to the change in capacitance of the piezo-actuator in a drive apparatus for gradually charging the piezo-actuators to expand them, by repeating turning-on/off of charging switch.
SOLUTION: Upon receiving an inputted drive signal Sd, the drive apparatus 1 repeats turning-on/off of a charging switch SW1, in a state where a discharging switch SW2 is in off-state, thereby charging the piezo-actuators P1-P4 to make them expand. After that, when the input of the drive signal Sd stops, the drive apparatus 1 repeats turning-on/off of the discharge switch SW2, in a state where the charging switch SW1 is in off-state, thereby discharging the piezo-actuators P1-P4 to make them shrink. Particularly, in the charge period, the drive apparatus 1 turns on the charge switch SW1 at a fixed period and turns off the charge switch SW1, when an integral value of the current, applied to a charging path 30 in on-state of the charging switch SW1, reaches a targeted charge quantity Q.
