Abstract: PURPOSE:To form a two-dimensional electron gas field-effect transistor in which InAs is easily used as an operating layer by disposing a high purity InAs layer, an InAs layer in which a P-type impurity is added, to be formed thereon, and an N-type AlXGa1-XAs layer having 0.22 or less of composition ratio of Al to be formed thereon on an InAs substrate. CONSTITUTION:A high purity InAs layer 13, an InAs layer 14 in which a P-type impurity is added, to be formed thereon, and an N-type AlXGa1-XAs layer 15 having 0.22 or less of X of the composition ratio of Al to be formed thereon are disposed on an InAs substrate 11. That is, the N-type AlXGa1-XAs having 0.22 or less of X of the composition ratio of the Al is employed to supply higher concentration electrons than those in case of employing N-type GaAs to an InAs operating layer. This is because the AlXGa1-XAs has larger conduction band state density than that of the GaAs. Thus, a two-dimensional electron gas field-effect transistor in which the InAs can be easily used as the operating layer can be formed without necessity of high growing technique such as AlGaAsSb/InAs hetero growth or the like.

Title: Data transmission system
Inventor: KUMAKURA KAZUMASA
IPC: H04L1/16
Filed: 1984-07-26
Abstract: PURPOSE:To attain the application of an ARQ transmission system to a transmission line having a long delay time by measuring the transmission delay time of a circuit deciding the number of blocks in a no-comprehension mode based on the result of said measurement in an ARQ transmission system. CONSTITUTION:In a facsimile transmission mode, the delay measurement signal is transmitted from a transmission side 1. Then the delay answer signal is sent to a circuit L from a reception side 2. The delay time due to the circuit L is measured at the side 1 by the delay answer signal. Based on the result of this measurement, a transmission control part 11 decides the number of the returned block data showing the specific block data at which the transmission is carried out again in case the answer signal is set in an NACK mode. Then only the side 1 received the no-comprehension signal indicates the number of returned blocks to the no-comprehension signal after the number of returned blocks is once decided. Thus the ARQ transmission is possible with a transmission line having a long delay time.
