Patent DD-145186-A3 (DD)
Title: Verfahren und vorrichtung zum nachweis der maximalen gasdruckbelastbarkeit von unterirdischen hohlraumspeichern oder abdeckformationen
Inventor: FOERSTER SIEGFRIED
IPC: E21B49/00
Filed: 1977-04-05
Abstract: Die Erfindung betrifft die Ermittlung der Gasdruekbelastbarkeit
unterirdischer Speicher·’ und Abdeckformationen, die zur
Gasspeicherung dienen bzw. vorgesehen sind. Durch die Erfindung werden
die Grundlagen für die Festlegung der wesentlichen Speicherparameter
und Möglichkeiten zur Bestimmung der zulässigen Gasdruckbelastungen in
Formationen zur Errichtung und den Betrieb von Kavernen geschaffen.
Das Wesen der Erfindung besteht darin, daß schwimmend an
Schwerstangen und Gestänge zwei Packer in Straddle-Anordnung
eingebaut und zur Begrenzung des Untersuchungsintervalls gesetzt
werden. Unterhalb der Packer befinden sich Manometerschutzrohre zur
Aufnahme von Tiefenraanometern und ein Soleaufnahmerohr. Zwischen den
Packern ist ein Druckausgleichsstück angeordnet, über das die im
Untersuchungsintervall stehende Flüssigkeit gegen das zu speichernde
Gas oder das Prüfgas ausgetauscht wird. Die pneumatische Rißbildung
erfolgt über einen weiteren zentrisch eingebauten Bohrstrang, der mit
einem Packerkopfstück gasdicht verbunden wird und nach erkannter
Rißbildung über eine Schließvorrichtung vom expandierenden
Iiohlraumvolum^„getrennt wird.

Abstract: A semiconductor detector of electromagnetic radiation which utilizes a dual-purpose electrode which extends significantly beyond the edge of a photodiode. This configuration reduces the sensitivity of device performance on small misalignments between manufacturing steps while reducing dark currents, kTC noise, and "ghost" images. The collection-mode potential of the dual-purpose electrode can be adjusted to achieve charge confinement and enhanced collection efficiency, reducing or eliminating the need for an additional pinning layer. Finally, the present invention enhances the fill factor of the photodiode by shielding the photon-created charge carriers formed in the substrate from the potential wells of the surrounding circuitry.

Abstract: An AC voltage regulator, which not only has a fast
response speed with respect to input voltage fluctuations
but also is small in size and light in weight and is capable
to boost an input voltage, comprises a high-frequency
transformer 4, a first bi-directional semiconductor switch
circuit 3, a second bidirectional semiconductor switch
circuit 5 and a third bidirectional semiconductor switch
circuit 6. An input AC voltage is ring-modulated by the
first bi-directional semiconductor switch circuit 3 and the
obtained ring-modulated voltage is transformed at a high
frequency by the high-frequency transformer 4 and then
demodulated by the second bi-directional semiconductor
switch circuit 5. The obtained AC demodulated voltage is
added to the input AC voltage to produce an AC raised
voltage. This AC raised voltage is pulse width modulated by
the third bi-directional semiconductor switch circuit 6,
which is controlled to become ON only while the second bi-directional
semiconductor switch circuit 5 is OFF, and the
AC raised voltage is continuously regulated by continuous
regulation of a duty ratio D of the second bi-directional
semiconductor switch circuit 6 in the pulse width
modulation.

Abstract: Initially, a client requests a specific document and provides the
preferences, including readability level preferences of the document,
locale preferences, content filtering instructions preferences,
governmental regulations preferences, natural language preferences, and
document syntactic format preferences. The transcoding proxy requests and
receives the document from the origin server, with the document having
origin semantic characteristics. The document from the origin server has
an origin readability level and origin locale, is conformant with origin
content filtering instructions and origin governmental regulations, and is
in origin natural language and in origin document syntactic format. Using
the client semantics preferences, the transcoding proxy revises the
document in a sequential or parallel fashion. The origin semantics
characteristics of the document are, thus, revised to the semantic
preferences specified by the client.

Abstract: At member registration step, a master transmits a
certificate and a priority to a slave. The certificate
indicates that the slave receiving it belongs to the

priority is used to solve a data conflict. At data
synchronization step, after it is determined that
members belong to the same data synchronization group
by the certificate, data synchronization processing is
performed between arbitrary members in which an input
device and a display device such as wrist watch are
limited. Data synchronization does not require a
