Patent JP-S61232670-A (JP)
Title: Manufacture of semiconductor device
Inventor: BABA TOSHIO
IPC: H01L29/737
Filed: 1985-04-08
Abstract: PURPOSE:To obtain a hetero-junction bipolar transistor operating at ultra-high speed by selectively purifying only the exposed section of a base layer and forming a semiconductor layer containing an impurity, which is changed into a single crystal on the surface of the base layer and into a polycrystal or amorphous on the surfaces of emitter and collector layers and obtains the same conduction type as the base layer. CONSTITUTION:Layers are etched up to an N-type Al0.3Ga0.7As collector layer 2 so that an operating region in a transistor is left and a P-type GaAs base layer 3 is exposed to a side surface. A natural oxide film only on the surface of the P-type GaAs base layer 3 in natural oxide films adhering on the surfaces is removed. When GaAs containing Be is grown in an MBE manner under the state, P-type GaAs grows in a single crystal on the surface of the P-type GaAs base layer 3 having no natural oxide film. On the contrary, polycrystalline GaAs having high resistance is shaped on the surfaces of the N-type Al0.3Ga0.7As collector layer 2, on which the natural oxide film is left, and an emitter 4. One parts of an insulating region 10 in the upper sections of the collector layer 2 and the emitter layer 4 are removed by etching to form a collector electrode 6, base electrodes 7 and an emitter electrode 8, thus completing a hetero-junction bipolar transistor through alloying.

Title: Trunk release control system
Inventor: MATSUDA TOSHIO
IPC: H04Q3/42
Filed: 1979-06-14
Abstract: PURPOSE:To decrease the number of the using relays and to prevent the rear-end collision of the next call after the end of talking by using the necessary and partial relay to the digit counting circuit. CONSTITUTION:When relay B has a reslease by the ring-off of the extension telephone, the velocity release is secured for relay group X excepting one of the digit counting circuits operating with the specified digit. And the delay release is given to one remaining relay Y in a longer time than the release time of relay B. Accordingly, the loop opening time to the main wire is delayed by the amount equivalent to the release time of relay B. However, the opening time is increased since the release time of relay C is delayed by the amount equivalent to the release time of relay Y. As a result, the rear-end collision can be avoided. Thus the number of the using relays can be decreased to attain a big economical effect for the release control of the central office trunk to prevent the rear-end collision when the connection is given to the next call after the ring-off between the extension and the main wire.
