Patent EP-0386736-A1 (EP)
Inventor: NAKAMURA KENJI
IPC: H04B10/29
Filed: 1990-03-07
Abstract: In an optical communication system, a transmitted signal (1) is modulated with a subcarrier signal having a frequency higher than the frequency of said transmitted signal on the transmission side, the modulated signal light emitted to a transmission channel. On the reception side (2), the received signal is filtered and decoded by means of a band-pass filter (23) having a center frequency approximately equal to the frequency of the subcarrier signal of the received signal. The above arrangement makes it possible to achieve an arrangement free from the influence of deterioration in the degree of modulation due to spontaneous emission generated from an optical amplifier disposed midway along the transmission channel. The optical amplifier (3) may be an optical differential gain amplifier which has the differential-gain optical input/output characteristics of outputting spontaneous emission of low intensity according to a digital signal value "0" and output light of high intensity according to a digital signal value "1". The arrangement enables optical amplification of signal light without the risk of outputting high-level spontaneous emission due to direct current excitation. It is therefore possible to provide received signals of high quality by eliminating any deterioration in S/N ratio and any   deterioration of the degree of modulation of signal light due to spontaneous emission from the optical amplifier disposed midway along the transmission channel.

Abstract: A method of repairing or modifying a turbine blade wherein damage or erosion has occurred to the end part of a turbine blade or it is required to remove the end part so as to improve the efficiency of the blade as a whole comprises the steps of removing the damaged end part or a part requiring replacement, securing a new piece of material to the blade which may or may not be partly preformed, and after securing of the new piece of material to the blade and heat treatment processes, subsequently working the new piece of material so that it conforms to the desired shape. The working of the new piece of material only after securement and heat treatment ensures that discontinuities such as lacing wire holes, shroud band apertures, tenons etc., are not left with concentrations of inbuilt stress due to the welding or heat treatment operations and if required the new part may be oversize material which ensures that if slight misalignment occurs between the blade and the new piece of material there is sufficient material to enable the part to be worked to the correct shape.

Abstract: The method and system for detecting occlusion in a fluid line upstream of a pump concerns a fluid pump with a pump cycle in which the upstream pressure of the fluid line is communicated to the downstream portion of the fluid line. A pressure sensor located downstream of the pump is capable of measuring a relatively large negative-going pressure in the fluid line. A signal is generated to indicate occlusion based upon detection of negative-going pressure.

Abstract: A polyarylene sulfide resin composition obtained by melt-mixing a mixture comprising resin components comprising as main resins
     (A) a polyarylene sulfide resin and   (B) a polyorganosiloxane graft copolymer obtained by graft-polymerizing one or more kinds of vinyl monomer containing at least an epoxy group-containing vinyl monomer onto a compound rubber in which a polyorganosiloxane rubber and a polyalkyl (meth)acrylate rubber have been inseparably united with each other.    The composition of the present invention, whether it contains a filler or not, is excellent in compatibility between the polyarylene sulfide resin and polyorganosiloxane graft copolymer. If this composition is extrusion-molded or injection-molded under the common molding conditions, it keeps its original dispersed and mixed condition without showing a phase separation. Consequently, this composition has an excellent performance that impact resistance also has been given to the polyarylene sulfide resin without largely injuring excellent properties inherent to the resin.
