Title: Procedure and device for leak testing of a volume and for determining the leaking amount.
Inventor: KNOPF RAINER
IPC: G01M3/28
Filed: 1994-12-28
Abstract: The invention relates to a procedure and a device for leak testing of a volume and for determining the leaking amount. By means of the procedure according to the invention and the associated device, a volume to be tested is first filled with a test liquid and saturated. The volume to be tested is then connected to a specially constructed measuring volume. The geometrical shape of the measuring volume is known. Losses of test liquid occurring in the volume to be tested are compensated by feeding corresponding adequate quantities of liquid from the measuring volume. The determination of the leaking amount is then carried out exclusively based on pressure measurements by means of a first and second pressure-measuring sensor, the first pressure-measuring sensor serving to determine the relative pressure between the measuring volume and the environment and the second pressure-measuring sensor being used to determine the differential pressure between the test liquid and a remaining volume above the test liquid in the measuring volume. By means of a pressure-generating device, in the case of a loss of test liquid caused by leakage, the pressure in the measuring volume is increased in such a manner that the sum of the relative pressure and the differential pressure is kept essentially constant. A determination of the differential pressures at the start and at the end of a predetermined measuring time and the knowledge of the geometrical shape of the measuring volume and of a calibration point then serves for the calculation of the actual leaking amount.

processing device which is capable of discriminating
the classification of a particular area of an image at

according to the present invention, an image input from
an image signal input portion (1) is processed in the
following steps: a vertical and horizontal complexity
calculating circuit (15) determines absolute values Tx
and Ty of differential densities between pixels
neighboring to each other in vertical and horizontal
directions, respectively, within a particular area of
the image; a diagonal complexity calculating circuit
(16) determines absolute values Rx and Ry of
differential densities of pixels neighboring to each
other in main diagonal and sub diagonal directions,
respectively, within the particular area; a comparator
circuit (17) compares sums of absolute values in
respective directions and outputs a least sum as a
complexity to an area discriminating portion (4); a
difference-comparator portion (3) determines a
difference between a maximal value Ma and a least value
Mi of densities of pixels of the image data and outputs
it as a comparison difference value to the area
discriminating portion (4); and the area discriminating 
portion (4) discriminates the classification of the
image area based on the above-mentioned complexity
value and comparison difference value.

Abstract: Power-on detection circuitry with almost
instantaneous response to a power-off condition includes
a network of several transistors (30, 32, 38, 40) and a
resistor (34). When a supply voltage (+VCC) used with
the circuitry is first turned on, the network produces at
the output (line 24) a short pulse which is subsequently
used to generate a power-on (PWRON) signal to reset or
initialize circuit elements termed "latches" (14). The
latches (14) in turn provide operating information to
other (main) circuits (16). A reverse coupled diode-connected
transistor (30) is provided to shunt to ground
charge stored in parasitic capacitance (36) at the input
when power is interrupted, such as by a sudden negative
voltage transient. This shunting action of the diode-connected
transistor (30) virtually instantly brings the
voltage at the input down almost to zero so that whenever
power comes back on another short pulse at the output is
sure to be generated. This short pulse at the output in
turn generates a new PWRON signal for re-setting the
latches (14) even though power has been interrupted for
only a few nanoseconds.

Abstract: A developer replenishing device for replenishing a

has a mouth portion at one end thereof which is smaller in
diameter than a hollow cylindrical main body. At the end of
the bottle provided with the mouth, a shoulder has the inner
periphery thereof partly raised to the edge of the mouth
portion to form a raised portion for scooping up a toner. In
addition, a part of the inner periphery of the circumferential
wall of the bottle which is contiguous with the raised portion
is also raised toward the axis of the bottle about which the
bottle is rotatable, thereby forming another raised portion.
When the bottle is mounted to a bottle holder, which is
included in the replenishing device, substantially horizontally
with the mouth portion oriented sideways, the bottle is
rotated to raise the toner from the bottom of the main body to
the mouth portion. As a result, the toner is discharged to the
