Title: Multivalued signal coding and decoding method
Inventor: TSUDA KENJIRO
IPC: H04N19/00
Filed: 1994-11-04
Abstract: PURPOSE: To improve coding efficiency by performing a coding by a binary coding method, deciding whether a multivalued signal should be coded by a multivalue based on a prescribed criteria or not, performing a coding by a prescribed multivalued coding method when the coding should be performed by the multivalue and eliminating the multivalued coding when the coding should not be performed by the multivalue. CONSTITUTION: When the intermediate level value of the transmittance of a multivalue signal 1 can be ignored, the multivalue signal 1 is threshold processed because the signal 1 is inputted in a thresholding means 2 and is compared with the threshold of the thresholding means 2 and a binary signal 3 is outputted from the thresholding means 2. When the binary signal 3 is inputted in a binary coding means 4, a binary coding is performed for the signal by an MR coding and a coding signal 5 is outputted from the binary coding means 4. Namely, in the first coding, the codings when transmittance is 100% or the other cases are performed, and, in the second coding, the intermediate level value of transmittance is regarded to be an ignored one when the the value is small and the coding is eliminated.

Title: Power semiconductor device
Inventor: FUDA MASANORI
IPC: H01L29/74
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To protect a power semiconductor device against damages by a method, wherein impurities used for forming a first conductivity-type layer or a second conductivity-type layer which forms the device are composed of donors or acceptors of different specific levels, so as to enable a current to flow uniformly through the device and the device to obtain high resistance, when a heavy current flows through it. SOLUTION: When diffusion layers are formed so as to form layers with different conductivity type by the use of impurities, one is of a shallow level below 0.05 eV and the other is of deep level 0.05 eV or more, free carriers are generated from impurities of deeper the level, the higher the temperature is, and free electrons and free holes are equal to each other in the diffusion layer, so that the diffusion layer becomes high in resistance. For instance, a power semiconductor, where impurities of deep donor level are injected into a P-type emitter layer a, rises in temperature when a current is concentrated at current turn on or turn off, free electrons increase in number, and the P-type emitter layer a becomes substantially high in resistance.  With this setup, current becomes less concentrated, and a power semiconductor device of this constitution enables protection against broakages.
