IPC: G10L25/00
Filed: 1990-02-23
Abstract: PURPOSE:To obtain a natural voice with less noises even in environment where the error rate of a transmission line is inferior by reproducing a voice signal by using the parameter of the synthesizing filter of a frame where an error correction is made and a driving signal. CONSTITUTION:A driving signal segmenting means 180 segments the signal for one pitch period from the accumulated driving signal when there is a specified or more error. A driving signal forming means 190 forms the driving signal for one frame by using the segmented signal for one pitch period. The synthesizing filter 200 is inputted with the formed driving signal and reproduces the voice signal of the frame where there is the specified or more error. An output means 220 outputs the voice signal reproduced when the specified or more error is detected. This means outputs a decoded voice signal when the specified or more error is not detected.

Title: Corrosion-resistant metallic material and its production
Inventor: FUJII KAZUMI
IPC: C23F15/00
Filed: 1994-03-11
Abstract: PURPOSE:To improve the corrosion resistance of a metallic substrate by coating the metallic substrate with a metal oxide which effects a change in electrode potential of the metallic substrate toward the nobler direction than the standard electrode potential of (the substrate metal)/(the metal ion) by reduction with the oxo-acid ions of the metal element of the metal oxide. CONSTITUTION:The layer 2 of a metal oxide such as Mob. is formed on the metallic substrate 1 consisting essentially of Fe, which metal oxide effects a change in the electrode potential of the metallic substrate 1 toward the nobler direction than the standard electrode potential of (the substrate metal)/(the metal ion) by reduction with the oxo-acid ions of the metal element of the oxide. Therefore, even when a corrosive substance X<-> is deposited on the substrate 1 to dissolve the oxide layer 2 and to form metal ions M<+>, the metal oxide is reformed from the metal ions M<+> in the oxide dissolving and reforming part 3 and the corrosion of the metallic substrate 1 is inhibited from occurring. Thus, the need of using an expensive highly corrosion-resistant metallic material as the substrate metal is eliminated and the corrosion resistance of the substrate 1 can be improved through using an inexpensive metallic material as the substrate metal.

IPC: H01L21/324
Filed: 1984-03-05
Abstract: PURPOSE:To enhance the safety and workability by preventing irregular evaporation of component atoms of a compound semiconductor substrate, thereby preventing the irregular electric characteristics in the substrate. CONSTITUTION:A dielectric protective film 2 is formed on the surface of a GaAs substrate 1 of a compound semiconductor substrate, and the substrate 1 is heat treated in the state that another two GaAs substrates 3, 4 are disposed at upper and lower sides of the substrate 1. The heat treatment is an annealing to form the interior of the crystal of the substrate homogeneous to heat at the temperature range of 700-1,200 deg.C of the temperature for starting diffusion in the impurity atoms and vacant lattice to the melting point of the crystal for 1- 40hr. The films 2 for suppressing the evaporation of partial component elements of high vapor pressure to coat the front and back surfaces of the substrate 1 is contacted with the substrates 3, 4. Thus, the temperature distortion of the protective film decreases at the temperature rising and falling times, and the possibility of breakage of the protective film decreases. Further, since the evaporation source is the solid GaAs substrate, its handling is simple, and the workability and the safety are improved.
