Abstract: A process of casting a scroll member for a scroll compressor including forming the scroll wrap member portions of equal height.  Unequal cooling of the scroll wrap when formed causes the hardness of the wrap to vary from radially outside to radially inside.  The radially outside portions of the scroll wrap are formed harder therefore reducing wear-out of the scroll member while the radially inside portions are formed softer, thereby permitting quicker run-in of the scroll set during initial startup of the scroll compressor.

Filed: 1996-01-16
Granted: 1999-10-12
Abstract: A voice signal transmission system reduces the amount of an increase in calculation, while suppressing possible deterioration of the performance, by an expansion in the distribution of a voice parameter representative of an envelope of a voice spectrum when an input voice having a plurality of frequency characteristics is treated simultaneously. A discrimination circuit discriminates, based on a voice parameter extracted by a spectrum parameter extraction circuit, another voice parameter obtained by quantization of the extracted voice parameter by a first quantization circuit and a further voice parameter obtained by quantization of the extracted audio parameter by a second quantization circuit, which one of either a third quantization circuit designed corresponding to the first guantization circuit or a fourth quantization circuit designed corresponding to the second quantization circuit should be used. Then, in accordance with a result of the discrimination, the third quantization circuit or the fourth quantization circuit quantizes a quantization error of the corresponding first guantization circuit or second quantization circuit as an error vector. On the reception side, the error vector is dequantized in accordance with the discrimination.
