Patent EP-0484631-A3 (EP)
Title: Videorecorder with equalizing circuit
IPC: H04N5/93
Filed: 1991-06-28
Abstract: In the signal path (1) for the frequency-modulated luminance signal of a video recorder, an equalising circuit (11) is disposed between the video band (2) and the frequency demodulator (3) which, whenever the luminance signals fall below a specific switching level (U16), operates in the mode of a bandpass filter (19) which is tuned to the carrier frequencies of the luminance signals and, whenever the luminance signals exceed this switching level in the direction of higher values, operates in the mode of an amplitude-controlled delay unit. In the latter mode, phase errors caused by recording and transmission are largely cancelled, whereas, in the former mode, oscillation patterns with deteriorated oscillations are again refreshed in terms of amplitude through the resonance effect. The height of switching level (U16) is set by a noise detection circuit (21) which detects the rate of the oscillations which do not pass through a specific detection level of the noise detection circuit situated in the vicinity of the sound point line of the frequency demodulator. The equalising circuit is thereby adapted to the different reproduction quality levels of different video tapes in such a way that image reproduction with minimum interference and maximum definition is achieved. <IMAGE>

Title: Heat-exchanger with a higher performance and hygiene level
IPC: A23L3/36
Filed: 1992-10-10
Abstract: Heat exchangers of high performance and high hygiene levels are produced from steel and galvanised. It has been found that a more stable and resistant structure is achieved by constructing the heat-transferring ribs by means not of plates, but of sheets 19 to 21, 23 to 25 arranged in a multiplicity of rows. The alternating use of sheets of different width permits different dividing spacings of the sheets to be achieved in the direction of passage of the air to be cooled, without the need arising for a corresponding number of gaps acting as balancing zones. Due to the elimination or substantial reduction of the number of gaps, the latter can be held so wide without essential impairment of the thermal performance that metal bridges are avoided in the case of galvanisation and the settling of foreign bodies which impair hygiene is suppressed during operation. <IMAGE>

Abstract: The one-way clutch mechanism of a torque converter
which has a short axial dimension, and which neither
produces a shock noise (an abnormal sound) nor
suffers a power loss in the idle mode thereof. An
outer race (30 in Fig. 1) is united with a stator
(18), and supports the stator (18) so as to be
axially movable and rotatable with respect to a
stationary shaft (16). The outer race (30) includes
a first side face (32) which is formed with first
teeth. An inner race (40) is united with the
stationary shaft (16), and includes a second side
face (42) opposite to the first side face (32).
The second side face (42) is formed with second
teeth which can prohibit the rotation of the outer
race (30) in one direction, by meshing with the
first teeth. The stator (18) and the outer race
(30) receive the axial component force of a fluid
stream which changes depending upon a speed ratio.
Thus, the unitary structure (18, 30) comes near to
or away from the inner race (40), thereby to engage
or disengage the first teeth and the second teeth.

Abstract: The present invention provides a processor apparatus for
processing a time domain reflectometry (TDR) signal having
a plurality of reflection pulses to generate a valid output
result corresponding to a process variable in a vessel and
a method for a process measurement signal. One method
includes the use of at least two different techniques for

two different techniques to provide weighted results.
Another method includes establishing an initial boundary
signal before the process variable is located in the
vessel, storing the initial boundary signal, detecting the
TDR signal, determining a baseline signal by subtracting
the initial boundary signal from the TDR signal,
determining a maximum value of the reflection pulse and
calculating an output result based on the maximum value.

Abstract: A heterojunction bipolar transistor and a method
for fabricating an HBT with self-aligned base metal
contacts using a double photoresist, which requires fewer
process steps than known methods, while minimizing damage
to the active emitter contact region. In particular, a
photoresist is used to form the emitter mesa. The emitter
mesa photoresist is left on and a double
polymethylmethacrylate (PMMA) and photoresist layer is then
applied. The triple photoresist combination is patterned
to create a non-critical lateral alignment for the base
metal contacts to the emitter mesa, which permits selective
base ohmic metal deposition and lift-off. By utilizing the
double photoresist as opposed to a metal or dielectric for
masking, an additional photolithography step and etching
step is eliminated. By eliminating the need for an
additional etching step, active regions of the
semiconductors are prevented from being exposed to the
etching step and possibly damaged.
