Abstract: WIDEBAND SUBCARRIER MULTIPLEXED           OPTICAL COMMUNICATION SYSTEM OPERATING OVER MORE THAN ONE OCTAVE            Abstract An optical communication system includes an optical transmitter for transmitting a subcarrier multiplexed optical signal through a single mode optical fiber to an optical receiver.

The  laser diode is preferably a high speed InGaAsP laser diode emitting in a spectral range of 1.3-1.6 micrometers.  The light beam is intensity modulated with a composite modulation signal to provide the optical signal for transmission.   The  composite modulation  signal includes multiple modulated microwave carriers that cover a total bandwidth greater than one octave. Harmonics  and  intermodulation products  do  not interfere  with  transmission,  and  a  favorable signal-to-noise  ratio  or  bit  error  rate  is maintained when the bandwidth of the composite modulation signal exceeds one octave.

Title: Transmitter circuit for efficiently transmitting communication traffic via phase modulated carrier signals
Inventor: ERNST GREGORY J
IPC: H03G3/30
Filed: 1989-09-08
Granted: 1993-07-20
Abstract: Abstract of the Disclosure Transmitter  for transmitting  communication  traffic via phase modulated carrier signals.  The device provides for an efficient amplification of a phase modulated carrier signal using Class C amplifier technology.   An envelope function is applied to the carrier signal by modulating the Class  C  amplifier with  a  related  spectrum-suppressing amplitude envelope signal.  Phase distortion accompanying the  amplitude modulation  of  the  Class  C  amplifier  is compensated by generating a phase offset for the carrier signal.   As each envelope function for suppressing the spectrum is generated, a corresponding phase offset may be applied to the carrier signal, avoiding the consequences of phase shift resulting from amplitude modulating the carrier signal in the Class C amplifier.

Title: Optical communication circuit with mode scrambler
Inventor: SHIGEMATSU MASAYUKI
IPC: H04B10/2581
Filed: 1989-09-29
Granted: 1993-03-30
Abstract: Abstract A mode scrambler is connected between a light source and an optical fiber coupler formed of a plurality of graded index, multi-mode optical fibers.  The mode of the input light signals can be converted to a random pattern mode through the mode scrambler, so that a steady excitation of the input light can be realized, including not only dominant lower modes but also higher modes of the input light signals, resulting in division of the input light signals without irregularity of the output light power.  This arrangement enables a semiconductor laser to be used as the light source without disadvantage, while taking advantage of the higher power of the semiconductor laser.

Abstract: In hydrodynamic bearings it is necessary for the lubricant leaving the lubricant film to be cooled. The self-sufficient, reliable operation of the system is only ensured if the transport of lubricant can be generated and maintained by the bearing itself. For this purpose the lubricant is taken from the contact surface of the moving component (2) into a pumping gap (13), recessed in the stationary component (4), which exhibits a strong constriction (17) in the direction of movement by a graduation (16). This pumping gap (13) may be machined directly in the contact surface of a bearing segment or in a separate component. A part of the lubricant stream which enters the pumping gap (13) is removed in front of the constriction (17) through an appropriate lubricant discharge duct (14). This branched lubricant stream (19) represents the delivery quantity of the pumping gap (13). The remainder of the branched lubricant stream flows on through the lubrication gap (18). The pumping pressure corresponds to the pressure built up hydrodynamically in the pumping gap (13).

Abstract: The invention relates to an optical device for measuring moisture in a substrate, in which device water is conveyed from the substrate along a porous absorption part (5) on a surface (4) of a prism so that is causes the critical angle of the total reflection to be changed thereon as a result of the change of the index of refraction. Another surface of the prism is dyed or patterned and covered in such a manner that it becomes visible only through reflection from the surface (4) when the surface is dry. When the surface (4) is moist, only the absorption part is visible through the viewing surface. The invention is advantageous in that due to the application of the principle of total reflection the change from an indication of the presence of moisture to an indication of the absence of moisture takes place sharply, not gradually.
