Title: Manufacture of reverse conducting thyristor
Inventor: MATSUZAWA TAKEO
IPC: H01L29/747
Filed: 1978-07-07
Abstract: PURPOSE: To remarkably reduce the forward voltage drop of diode, by constituting the reverse dielectric strength of the diode which constitutes the thyristor so that it takes a balanced value as the reverse voltage of the thyristor part without taking the value more than required value.  
     CONSTITUTION: The N type Si substrate 1' is heated in wet oxygen, the SiO 2  film 2 is grown on the both sides of front and rear, one film 2 is removed, B is diffused in wet oxygen, the P type layer 3 is formed, and the SiO 2  film 4 is produced on it. Next, the films 2 and 4 at the both sides of rear and front are selectively removed, and Ga 70 wt.% and P 30 wt.% are diffused from the both sides at the same time. Since Ga passes through the films 2 and 4, the P type region 7 is produced under the films 2 and 4, P is strongly diffused to the region not covered with the films 2 and 4, producing the N +  type region 6 and the N type region 5. Accordingly, by selecting the composition and temperature for Ga and P, the depth of the regions 6 and 7 is given as specified depth, and it is possible to reduce the forward voltage drop of the diode part by several tens of percentage as conventional value without decreasing the dielectric strength of the thyristor part.

Title: Method and device for quantizing vector
Inventor: BIN KATSUTAKE
IPC: G10L25/03
Filed: 1993-03-19
Abstract: PURPOSE:To effectively quantize a vector by setting a centroid by extracting prescribed feature vector from a largest cluster to which the most feature vectors are attached at the time of generating a null cluster where the feature vector does not exist. CONSTITUTION:A centroid generating part 141 generates a vector to be a centroid based on the feature vector from a feature vector extracting part 13. The number of feature vectors detection part 143 detects the number of the feature vectors attatched by a clustering part 142 by each cluster to discriminate the largest cluster to which the presence/absence of the null cluster and the feature vectors are extremely attached. When the null cluster is generated, the null cluster processing part 142 extracts the feature vector extremely separated from the centroid from the largest cluster. The extracted feature vector is defined to the new centroid of the null cluster. Thereby, quantization can be executed without resigning clustering calculation.
