Title: Remote synchronizable time indicator
Inventor: STURZL WILHELM
IPC: G04R20/08
Filed: 1990-10-25
Abstract: Abstract A remote synchronizable time indicator (25), in particular, in the formof a time switch having a switching range (31) to control a load (33), is to be laid out so that it can also be operated at those locations, during corrective monitoring of an absolute time information (13), where the long-wave carrier frequency (f) of a public time transmitter cannot be readily received, such as in a low-lying installation room of a building (11).  For this purpose, the time indicator (25), which in itself is operated autonomously from a time-keeping circuit (27) and which can, if necessary, be periodically corrected via a comparator (23) in accordance with the actual absolute time information (13), is equipped with an indicator-receiver (20) for the carrier-frequency converted transmission of the absolute time information (13) which takes place via a local transmission line (17) in the form of the AC power supply of a house (32) and/or a short-wave channel.  This local transmission line (17) is fed in the building (11) or in the vicinity of the building (11) from a converter-receiver (14) which is positioned in such a way that it can advantageously receive the long-wave carrier frequency (f) of the absolute information (13) received from a public time transmitter, whereby the local transmission line (17) is fed with a local transmission frequency (F) which has been increased via frequency converters (16).

Abstract: An electroluminescent device includes a semiconductor layer (4) in the form of a thin dense polymer film comprising at least one conjugated polymer, a first contact layer (5) in contact with a first surface of the semiconductor layer, and a second contact layer (3) in contact with a second surface of the semiconductor layer. The polymer film (4) of the semiconductor layer has a sufficiently low concentration of extrinsic charge carriers that on applying an electric field between the first and second contact layers across the semiconductor layer so as to render the second contact layer positive relative to the first contact layer charge carriers are injected into the semiconductor layer and radiation is emitted from the semiconductor layer. The polymer film can be poly (p-phenyenevinylene) [PPV] of formula (I) wherein the phenylene ring may optionally carry one or more substituents each independently selected from alkyl (preferably methyl), alkoxy (preferably methoxy or ethoxy), halogen (preferably chlorine or bromine) or nitro. A method of manufacture of an electroluminescent device includes steps of depositing a thin layer of a precursor polymer onto a substrate and then heating the precursor polymer to a high temperature to form the conjugated polymer.
