Title: Reception signal collision detector
Inventor: SUZUKI HIDEKI
IPC: H04L12/28
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To detect a collision no matter which part the collision is generated in, to identify a data error and the collision and to clearly report the collision further by detecting unique words in the different parts of reception signals. SOLUTION: When first unique word detection signals 202 become active, a collision detection part 104 is turned from an idle state to a normal state and is turned to the state of detecting the collision during data reception thereafter. In this case, in the case that prescribed time elapses and second unique word detection signals 203 do not become active, it is judged that the collision between reception bursts is generated and reception collision detection signals 207 are made active. Also, when a transmission timing becomes active, the collision detection part 104 is turned from the idle state to a transmission state and is simultaneously turned to the state during transmission and reception collision detection.  In the state during the detection, when a second unique word is not detected within the time range of an already known burst length, the collision generation between the bursts is judged.

Filed: 1985-03-15
Abstract: PURPOSE:To simplify an apparatus of an optical system by using a photodetector constituted by packaging two APDs onto the same chip and attaching polarizing plates which are respectively different in the axial directions to the front of the photodetecting surfaces. CONSTITUTION:A light signal of which the polarization direction is in an X axis and a light signal of which the polarization direction is in a Y axis are fed through a polarization plane maintaining type optical fiber 1. The photodetector 8 is constituted by disposing the two APD9 and APD10 on the same chip in such a manner that the respective photodetecting surfaces are positioned on the same plane and in the same direction. The polarizing plate 9a is attached to the photodetecting surface of the APD9 and the polarizing plate 10a is similarly attached to the photodetecting surface of the APD10. The plate 9a allows the transmission of only the light signal of which the polarization direction is in the X axis. The plate 10a allows the transmission of only the light signal of which the polarization direction is in the Y axis. The number of the apparatus of the optical system is thus decreased and the package over the entire part of the device is made smaller in size.

Filed: 1985-03-15
Abstract: PURPOSE:To suppress the effect of lattice scattering and to obtain high electron mobility even under the state a high electric field is applied, by the constitution, wherein a compound semiconductor in the second layer has the lattice constant larger than the lattice constants of compound semiconductors in the first and third layers. CONSTITUTION:In the structure of an FET as shown in the Figure, the lattice constants are as follows: 6.479Angstrom  for InSb; 5.654Angstrom  for GaAs; and 5.662Angstrom  for AlAs. Therefore, the lattice constant of the InSb layer 12 is extremely larger than those of GaAs and GaxAl1-xAs. Therefore, in the vicinity of the interface between the GaxAl1-xAs layer and the InSb layer, the cubic lattice of InSb is deformed into the tetragonal lattice by elastic strain. IN the FET structure, an uppermost Ga0.7Al0.3As layer 14 can be made to be a complete depletion layer by controlling a voltage applied to a gate electrode. Since a GaAs substrate 10 and a GaAs epitaxial layer 11 have high resistance values, the FET, in which only the InSb layer 12 is made to be the channel layer, can be obtained.
