Title: Epitaxial crystal growth method
Inventor: HAYAFUJI AKIO
IPC: H01L21/20
Filed: 1986-10-02
Abstract: PURPOSE:To obtain a high-quality epitaxial growth layer which does not deteriorate its characteristic due to the difference in the lattice constant by a method wherein, after a semiconductor substrate has been doped, in advance, with a high concentration impurity, an epitaxial crystal growth is executed on the substrate. CONSTITUTION:A high-concentration impurity layer 2 is formed, e.g., on an si substrate 1 or inside the substrate 1. As an impurity, e.g., sb is used. During this process, it is possible to freely change the surface-layer lattice constant at the layer 2 through the concentration of sb. In addition, a defect which is caused by the difference in the lattice constant between the layer 2 and the substrate 1 does not cause a new defect in such a way that the layer is bent between precipitated Sb's or is fixed. Then, an epitaxial growth layer, e.g., a GaAs layer 3, is grown on the layer 2. If, during the above process, the surface lattice-constant at the layer 2 is brought close to the lattice constant at the layer 3, it is possible to form the layer 3 which contains few defects.

Title: Communication disable time reduction system in network system
Inventor: TSUKAGOSHI MASAHITO
IPC: H04L12/28
Filed: 1989-09-14
Abstract: PURPOSE:To shorten a period for communication disable state after the occurrence of a fault by allowing a management terminal equipment managing a trunk line LAN to control a fault bridge and a switching bridge and applying multiple address transmission to the address of the fault bridge and the switching bridge in the trunk line LAN to all bridge. CONSTITUTION:A management terminal equipment 5 managing a trunk line LAN 1 controls the fault bridge 3 (causing a fault) and the switching bridge 3 (a bridge being active from the standby state) and the address 7 of the fault bridge 3 and the switching bridge 3 in the trunk line LAN 1 is applied to the multiple address transmission to all bridge 3 in the system. Since the bridge 3 receiving the address information recognizes the occurrence of the fault, the bridge 3 updates its own filtering database.

Title: Device for encoding and decoding television signal
Inventor: TAKIZAWA MASAAKI
IPC: H03M7/38
Filed: 1985-10-25
Abstract: PURPOSE:To insure the vertical resolution of a still part against dropping even at the time of field framing by generating an interpolation signal through the use of a television signal in the 1st field so as to replace it with a signal in the 2nd field only when there is a significant difference between frames in terms of the 1st field to be transmitted. CONSTITUTION:The difference between a digitized television signal and a television signal delayed by one frame by means of the two field memories 3 and 4 is calculated by a subtractor circuit 5. If the output of the subtractor circuit 5 exceeds a set threshold, an inter-frame significant difference deciding circuit 20 outputs '0': otherwise, it outputs '1'. A timing circuit 12 outputs '0' and '1' if a signal is in the 1st field and the 2nd one, respectively. An OR circuit 22 outputs zero if an input is zero: other wise, it outputs '1'. If the output of the OR circuit 21 is zero, a switch 22 is connected to an upper side, and interpolation is made by inputting the output of an adder circuit 10 to the field memory 3. If the output is '1', the switch 22 is connected to a lower side and inputs the output of the field memory 4 to the field memory 3 as it is.

Inventor: ASAHI HITOSHI
IPC: C21D8/10
Filed: 1992-09-04
Abstract: PURPOSE:To obtain an austenitic fine-grained structure only by seamless rolling. CONSTITUTION:High temp. hollow steel pipe stock produced by subjecting a slab heated to a high temp. to piercing and rough rolling is cooled to the Ar3 point to 1100 deg.C before a gradient rolling mill in the final stage, and working is executed at 20 to 70% reduction rate of cross-sectional area by a gradient rolling mill located immediately after that, by which fine-grained austenite can be obtd.

As for the gradient rolling mill, the components of shearing strains are very big, and the grains finer than those by an ordinary rolling mill can be obtd. even though the same reduction rate of cross-sectional area. Furthermore, since its recrystallization occurs dynamically, the grain size is decided only by temp. without depending on the amt. to be worked, so that the fine-grained steel can be obtd. by executing the gradient rolling under low pressure.

IPC: G10K15/12
Filed: 1989-09-13
Abstract: PURPOSE:To improve throughput by executing a program which realizes a digital filter, and simultaneously operating a pair of digital processing circuits. CONSTITUTION:When the program which realizes the digital filter is executed, a pair of digital processing circuits 9 and 10 are simultaneously controlled by a control signal outputted from a control circuit 14. As a result, the sums of products are simultaneously operated for two input data, namely for the data of a left channel and a right channel, and a filter is operated. Thus the double throughput can be obtained compared with a conventional case. Further when different filter characteristics for the right and left channels are obtained, after different constants are stored into the respective digital processing circuits 9 and 10, the same sum of products operation is executed, and thus the double throughput is obtained.
