Patent EP-0380361-A3 (EP)
Title: Transmitter circuit with gallium arsenide field effect transistor
IPC: H04B1/04
Filed: 1990-01-26
Abstract: A transmitter using a gallium arsenide FET (27) in a 
power amplifier (26) and having a biassing circuit for 
generating a gate biassing voltage for the FET, a first 
power supply (29) for supplying a first power to the biassing 
circuit and a second power supply (30) for supplying a second 
power to the power amplifier, the second power being 
higher in voltage than the first power and being 
produced at a time delay from production of the first 
power at a start condition of the transmitter, wherein 
the first power is supplied to the biassing circuit 
through a first diode (31) with a voltage drop to thereby 
reduce the gate biassing voltage below a normal one so 
that an undesired signal is suppressed at the power 
amplifier. The second power is delivered to the 
biassing circuit through a second diode (32) so that the 
biassing circuit is driven by the second power to 
produce the normal biassing voltage. Although a 
multistage amplifier is used for signal amplification 
prior to the power amplifier and is supplied with a 
power from the second power supply, a number of stages 
of the multistage amplifer is not necessary to be 
increased for attenuating the undesired signal at the 
start condition because of the signal suppression of the 
power amplifier.

Title: Audio amplifier with phase modulated pulse width modulation
IPC: H03K17/00
Filed: 1990-02-28
Abstract: An audio amplifier operating at a high frequency many times higher than the highest frequency of the audio signal involves a digital switching system for a phase modulated dc-to-ac converter modified to provide a high fidelity audio amplifier. First and second switching mechanisms (40, 42, 56, 58) are respectively associated with the primary and secondary sides of an isolation transformer (46), the first switching mechanisms being driven by a square wave reference signal of fixed phase and the second switching mechanisms being driven by the square wave reference signal with various diodes for clamping steering or controlling the polarities of the outputs of the second switching mechanisms to provide a phase modulated pulse width modulation and high fidelity amplification particularly adapted for stereo application.
Patent EP-0390563-A3 (EP)
IPC: G06N5/04
Filed: 1990-03-29
Abstract: In a method (claim 1), an inference is conducted 
by use of fuzzy knowledge and knowledge of experts can 
be directly written in inference rules. In a method 
(claims 2 to 4), it is possible to use ambiguous language 
expressions of the user and the user can freely describe 
flexible knowledge, although ambiguous, in a knowledge 
base. In a method (claims 5 to 7), the user clearly 
specifies execution priority orders or conviction degrees 
of inference rules such that even when an antecedent 
contains a confirmative or determinant action, a conten­
tion between rules is prevented to execute an optimal 
inference rule in any situation. In a method (claims 
8 to 15), an intermediate result of a fuzzy inference 
is passed in a form of a real number or a fuzzy label 
to the next inference to achieve a fuzzy multi-stage 
inference, thereby conducting an inference more similar 
to the human inference as compared with a single-stage 
inference. In a method (claims 16 to 18), a multi-stage 
inference conducting a backtrack operation based on fuzzy 
knowledge is implemented to easily reflect user's 
ambiguous knowledge onto inference rules. In a method 
(claims 19 to 26), a new infernece method associated 
with a best value retrieval function is provided wherein, 
in contrast to the conventional method in which a fuzzy 
inference and a binary logic inference are continuously 
 
 
achieved from an upper-level retrieval or search point 
to a lower-level retrieval point in a one-directional 
manner, the best value retrieval function is employed, 
thereby easily obtaining an optimal solution. In a method 
(claims 27 and 28), the user can describe inference rules 
without perceiving any difficulty of a description of 
the termination instruction to terminate an inference 
at a satisfactory inference stage, thereby configuring a 
system which matches with the human fuzziness and which 
can be easily operated by the user.

Title: Apparatus for encoding digital signals
IPC: H04B1/66
Filed: 1991-03-06
Abstract: Apparatus for efficiently encoding a digital signal includes an arrangement (41, 42) for dividing the signal into a number of frequency band signals. The frequency band signals are segmented into blocks and the blocks are orthogonally transformed (43, 44, 45) to form coefficient data. The coefficient data is then quantized (58). A circuit (50) detects whether at least the lowest frequency one of the frequency band signals contains a transient. If so, a control circuit (57; 102; 100) controls processing of at least the lowest frequency band signal so as to reduce the perceptibility of noise in the processed signal. The control circuit may be operative, in the event of detection of a transient, to increase the number of bits used for quantizing at least the lowest frequency band signal, to reduce the block size of at least the lowest frequency band signal, and/or to reduce the level of at least the lowest frequency band signal. <IMAGE>

Title: Tanks with internal jacket made out of polymer material
Inventor: PHYROGENIS CHRITOS
IPC: B65D81/38
Filed: 1993-07-29
Abstract: The invention concerns the construction of tanks with inner lining from appropriate polymer material, which (i.e the lining) has the form of a jacket and a shape similar to the corresponding tank, for the purpose of corrosion or other kind of protection of the inner side of the tanks from liquids which are stored or circulated through the tanks. The use of internal jacket from polymer material (12), in direct contact with the walls of the tanks, creates a new product which can have many applications and as an example only reference is made to the storage water heaters (solar, electric, etc.) where the need of the corrosion protection of the tanks is satisfied by the use of the internal jacket from polymer material which is resistant to corrosion, while the need for strength to hydraulic pressure is satisfied by the tank itself (usually made out of steel) and this combination has important economical and technical advantages. The basic method for the production of the new product, in accordance with the invention, includes either the production of a tank from a pre-constructed jacket from polymer material (12)(i.e. polyethylene, polypropylene, etc.), which (jacket) is enclosed by the various parts of the tank (13,14,15), whose parts are assembled by welding, screws, etc., or the production of the tank by forming the jacket from polymer material directly inside the tank.
