  • Publication number: 20210018570
    Abstract: A waveform designator designates a given waveform of an AC signal by specifying a frequency as a reference. A signal controller causes a storage battery to output a response signal based on its own power. A detector detects a frequency component in the response signal corresponding to the reference frequency of the AC signal based on a product of the reference frequency and the response signal. A calculator calculates a complex impedance of the storage battery based on the frequency component in the response signal. A noise determiner determines presence or absence of a noise signal corresponding to the reference frequency of the AC signal before the signal controller causes the storage battery to output the AC signal. A noise controller either avoids or removes the noise signal.

    Abstract: A battery monitoring apparatus includes an electric power supply terminal connected with a first electrical path, a voltage input terminal connected with a second electrical path, a signal control unit connected with a third electrical path, a response signal input terminal connected with a fourth electrical path, and a calculating unit. The signal control unit is configured to cause a predetermined AC signal to be outputted from a storage battery with the storage battery itself being an electric power source for the output of the predetermined AC signal. The calculating unit is configured to calculate, based on a response signal of the storage battery to the predetermined AC signal, a complex impedance of the storage battery. Moreover, at least one of the first to the fourth electrical paths is merged with at least one of the other electrical paths into an electrical path that is connected to the storage battery.

  • Publication number: 20200088309
    Abstract: A spool valve unit includes a sleeve member having a high-pressure port and a low-pressure port, a spool member movably accommodated in the sleeve member in an axial direction, and a spring member for biasing the spool member in a first axial direction. The spool valve unit produces an intermediate fluid pressure to be outputted to an outside of the spool valve unit, when electromagnetic force is applied to the spool member so that the spool member is moved at a high speed between the high-pressure port and the low-pressure port. The spring member is composed of a non-linear spring, a biasing force of which is non-linearly changed with respect to a displacement of the spool member.

  • Publication number: 20200089261
    Abstract: A current control device includes a target setting unit, a storage unit, an oil pressure ratio calculation unit, a specific current detection unit and a correction unit. The target setting unit adds a dither amplitude to a target current so that the current of the solenoid periodically changes at a dither cycle period longer than a PWM cycle period of the solenoid. The storage unit stores a stroke-current relationship between a stroke of the spool and the current of the solenoid. The oil pressure ratio calculation unit calculates an oil pressure ratio which is a value calculated by dividing an amplitude of the output oil pressure by an average value of the output oil pressure. The specific current detection unit detects a specific current based on the oil pressure ratio. The correction unit corrects the stroke-current relationship based on the specific stroke and the specific current.

  • Publication number: 20190265858
    Abstract: A display controller controls changing timing of a waveform of each of gate clock signals (GCK1, GCK2) so that a display driving operation is performed after the lapse of a relatively short time from a starting point of time of a horizontal scanning period in odd-numbered horizontal scanning periods (Ho), and that a display driving operation is performed after the lapse of a relatively long time from a starting point of time of a horizontal scanning period in even-numbered horizontal scanning periods (Ho). A touch panel controller outputs a pulse of a touch drive signal (STD) so that a position detection operation on a touch panel is started in a stable period after an end of the display driving operation in each of the odd-numbered horizontal scanning periods (Ho).
