Patent DE-19928361-A1 (DE)
Inventor: SAUMER MARKUS
IPC: G05B19/23
Filed: 1999-06-21
Abstract: The method uses a predetermined distance signal with a number of travel pulses proportional to the path to be driven by the rotor of the stepper motor. A target position signal is formed by counting the pulses. The target position is converted into a micro step signal and is provided as a position target value of a position control loop to position the stator rotation field of the motor. The time difference between successive pulses is measured and the positioning speed is derived from this difference and the path length associated with each pulse. The speed is compared with a reference speed. If the speed is less than the reference, the stator field is driven with a set speed until it has reached the target position. If the positioning speed is greater than the reference, a speed control controls the speed. Independent claims also cover an electric drive.

Patent EP-1037063-A1 (EP)
Inventor: KIKUCHI YOSHIAKI
IPC: H02J7/02
Filed: 2000-03-10
Abstract: By finding a voltage difference ΔV between the maximum value and the
minimum value of voltage of each cell constituting a battery set and then
combining the voltage difference ΔV with current I passing through the
battery set into a value pair and store a plurality of the value pairs, the
relationship between the voltage difference ΔV and the current I is a relation
represented by a straight line with the slope ΔR thereof corresponding to an
internal-resistance difference. Therefore, fault in the battery set can be
determined from the magnitude of the slope ΔR computed by a least-squares
method. Fault determination for a battery set is made more accurate because
variations in electromotive force caused by charge-and-discharge patterns and
by changes in temperature are canceled when the voltage difference ΔV is
determined.

Abstract: A position detecting device which detects a position of
a piston rod based on the time for an
ultrasonic wave to be emitted from a sensor (11) toward
a lower surface of the piston (6) in a hydraulic
cylinder (5), reflected by the surface of the piston and received by

Abstract: A liquid jetting apparatus of the invention includes a
pressure chamber having an inside space whose volume is changeable,
into which a liquid is supplied and which is communicated with
a nozzle. A Helmholtz resonance frequency of the pressure
chamber has a period of TH. A signal-generating unit generates
a driving signal, which includes a first signal-element (Tc1) for
causing the pressure chamber to expand, a second signal-element (Tcl)
for causing the pressure chamber to contract from an expanded
state thereof in order to jet a drop of the liquid through the
nozzle, and and a third signal-element (Tc2) for causing the pressure
chamber to expand to an original state before outputting the first
signal-element after the drop of the liquid is jetted. A
pressure-generating unit causes the pressure chamber to expand
and contract, based on the driving signal. An interval between
a starting time of outputting the first signal-element and a
starting time of outputting the second signal-element (T1) and an
interval between a starting time of outputting the second
signal-element and a starting time of outputting the third
signal-element (T2) are set substantially equal to the period TH of
the Helmholtz resonance frequency. A sum of an amplitude of the
first signal-element (V3) and an amplitude of the third signal-element (V2)
is set substantially equal to an amplitude of the second
signal-element (V1).
