Patent EP-0523893-A3 (EP)
Inventor: ROBINSON BARRY J
IPC: H03K19/086
Filed: 1992-07-06
Abstract: A low voltage current mirror termination circuit used with an ECL gate array for providing a constant output emitter follower reference current (Ief) which is independent of voltage variations in a separate output emitter follower power supply source (VEF) includes a lateral PNP transistor (Qp), an NPN mirror transistor (Qx), at least one pull-down transistor (Qf), and at least one NPN output emitter follower transistor (Qo). The current through the collector of the lateral PNP transistor (Qp) defines a mirror current (Ip). The base of the lateral transistor (Qp) is connected to receive a base bias voltage VEP. The current through the collector of the pull-down transistor (Qf) defines the constant output emitter follower reference current (Ief) which is proportional to the mirror current (Ip). The separate emitter follower power supply source (VEF) has a voltage which is lower than a supply source (VEE) so as to reduce significantly the power consumption. <IMAGE>

Title: Synchronous detecting apparatus and synchronous detecting and protecting method.
Inventor: MINEMATSU TORU C O SONY CORPOR
IPC: H04L7/08
Filed: 1993-06-30
Abstract: A synchronous detecting apparatus for detecting a synchronizing signal transmitted at intervals of predetermined data units. The synchronizing signal includes a first synchronizing signal made of a first signal pattern and a second synchronizing signal composed of a second signal pattern, part of the second signal pattern being common to the first signal pattern. The synchronous detecting apparatus comprises a synchronizing signal detecting circuit (37), a synchronism establishment detecting circuit (38) and a control gate (71). The synchronizing signal detecting circuit (37) includes a common gate (70) for detecting the part common to the first signal pattern and to the second signal pattern; a first pattern detecting gate (68) for detecting that part of the first signal pattern which differs from the second signal pattern; and a second pattern detecting gate (66) for detecting that part of the second signal pattern which differs from the first signal pattern. The synchronism establishment detecting circuit (38) detects the establishment of synchronism based on the synchronizing signal detected by the synchronizing signal detecting means (37) and outputs a synchronism establishment detecting signal accordingly. The control gate (71) suppresses the output signal of the common gate (70) as the object of synchronous detection in accordance with the synchronism establishment detecting signal. The invention also relates to a synchronous detecting and protecting method for providing the detection and synchronous protection of the synchronizing signal. <IMAGE>

Title: Device for mounting or taking down a curtain from a rail.
IPC: A47H13/00
Filed: 1993-10-13
Abstract: The invention relates to a device for mounting or taking down a curtain from a rail, the curtain having suspending elements with T-shaped sliding heads and the rail possessing, on its underside, a guide slot running in the longitudinal direction of the rail and intended for guiding through the suspending elements. The sliding heads are pivotable through 90@ against spring action and can then come out of the guide slot of the rail. A hang-up magazine with an entry channel for the suspending elements can be attached in the region of the guide slot. The hang-up magazine additionally has a control curve with a narrowing, such that the sliding heads of the entering suspending elements are turned through 90@ via a cam and can thus be transferred from the rail to the hang-up magazine, in which process the suspending elements are securely guided by guiding flanges in a guiding curve of the hang-up magazine. The hang-up magazine furthermore possesses a flexible magazine bar which eventually receives all suspending elements, so that the curtain in question can be taken out of the rail or conversely introduced into it again. The hang-up magazine can be folded up by virtue of the flexible magazine bar to form a package which is suitable for passing through openings of washing machines, with the result that the curtain can be washed together with the hang-up magazine. <IMAGE>
Patent EP-0588577-A3 (EP)
IPC: H01L23/31
Filed: 1993-09-13
Abstract: The present invention provides hermetically sealed 
integrated circuits which can have a standardized arrangement 
of external contacts. These circuits comprise a circuit 
subassembly (1) having external contacts (2). Onto the surface of 
the subassembly surrounding the external contacts is formed a 
first ceramic passivating layer (3). Next, a non-corroding, 
conductive layer (4) is formed on the external contacts and 
portions of the first ceramic passivating layer. Then a 
second ceramic passivating layer (6) is formed on the 
non-corroding, conductive layer and that portion of the first 
passivating layer not covered by the non-corroding, 
conductive layer. Finally, the second passivating layer is 
etched through to the conductive layer to allow external 
contact with the circuit. The present invention also relates 
to methods for producing the above integrated circuits.

Title: Improved patient support systems and methods for automatically turning patients and for relieving pressure points.
Inventor: THOMAS JAMES MILTON CHERRY
IPC: A61G7/05
Filed: 1990-03-07
Abstract: A low air loss patient support system (20) includes a plurality of identical multi-chambered inflatable sacks (34). A restrictive flow hole (64) connects two adjacent chambers (46, 54) disposed predominately to one side of the centerline of the sack, and each side is separately pressurizable under the control of a microprocessor (160) and a plurality of pressure control valves (162) with pressure transducers and a plurality of flow diverter valves (220) for switching between different modes of configuring the manner in which the sacks are pressurized. The system includes a modular manifold (128) for mounting the pressure control valves (162), and a modular support member for mounting the sacks via quick-disconnect couplings and having air flow channels defined therethrough. The support system can rotate or tilt the patient by depressurizing one side of the sacks (34) while increasing the pressurization of the opposite side of the sacks. An end chamber (46) of the depressurized side of each sack remains inflated while the adjacent intermediate chamber (54) becomes progressively deflated during depressurization to permit the end chambers to restrain the patient from sliding off the sacks during tilting. The support system can relieve pressure points between the patient and the sacks while elevating the head and chest of the patient by reconfiguring the diverter valves (162) to connect alternating sacks at the same pressure and periodically decreasing the pressure in one group of sacks while increasing the pressure in another group of sacks alternately to relieve the pressure of and on the patient between the two different groups of sacks depending upon which group is depressurizing and which group is being increased in pressure.

Abstract: A method for thermally stabilizing two columns for liquid chromatography
comprises the following steps: operating the first column at a first temperature
which is different from the operating temperature of the second column, and
transferring the sample contained in the first column to the second column by
operation of switching means arranged between the two columns. In an
embodiment of the invention, the first column is a pre-column (102) and the
pre-column is operated, during an enrichment phase, at a first temperature
lower than an operating temperature of the separation column, in order to
maintain a sample at a first temperature, the sample contained in the pre-column
is heated, after completion of the enrichment phase, to a second
temperature higher than the operating temperature of the separation column
(104), then the sample contained in the pre-column (102) is transferred to the
separation column and then the sample is cooled to the operating temperature
of the separation column.

     Es wird hiermit nun eine Anlage angegeben, deren Bauaufwand
gegenüber den bisher bekannten Anlagen bei außerdem verbessertem
Wirkungsgrad erheblich reduziert ist. 
     Bei dieser Anlage zur biologischen Aufbereitung von Abwasser,
insbesondere kommunalem Abwasser, bei der das Abwasser
nacheinander mehrere, nach speziellen Aufgabenstellungen getrennte
Becken durchläuft, sind mindestens zwei ringförmige
Becken (2; 3; 4) konzentrisch um ein kreisförmiges
