The plastically deformed layer in a machined surface m is. be Considered in precision machining process. Therefore the analysis of the machined surface. including the plastic deformation and strain distribution should be carried out quantita-tively. The subsequent recrystallization technique was presented for analysis of the plastically deformed layer in the machined surface, and the technique was successfully applied to determine the plastic strain in the machined surface. This investigation is to evaluate the plastic strain in the distance 0.1mm from the machined surface, and in particular, to find the elect of shear angle, shear strain. cutting energy etc. on the plastic strain.

Studies were carried out to investigate phenotypic expression, mortality and biochemical analysis of haemolymph proteins of nm-d, nm-f, nm-i, nwr-k and nmn non-molting mutants of the silkworm, Bombyx mori. The non-molting mutants characters were expressed in the homozygote of each mutant genes. All strains of non-molting mutants were similar with each other in physiological characteristics, but the expression varied with each strains. The larvae of nm-d, nm-i and nwfn died between day 5 and day 9 after hatching without the first molt. The nm-f and nm-k mutants died between day 5 and day 16 with a slight increase of body weight and, more than 90% of the mutants larvae died before the first molt and a few of them survived to the 2nd and the 3rd instar and died. The haemolymph protein components of nm-d,nm-i and nmn were rapidly reduced , and on the other hand those of nm-f and nm-k consistently until they died. And there were no distinguishable difference in haemolymph components of non-molting mutants, as compared to those of normals.
