Abstract: PURPOSE:To provide a method of manufacturing the quantum fine wire structure of a compound semiconductor device which is of low damage, high density and excellent controllability. CONSTITUTION:A buffer layer 102, a barrier layer 103, a quantum well layer 104 and a barrier layer 105 are successively formed by crystal growth. Then an oxide film 106 is built up and a resist pattern 107 is formed by lithography. The oxide film 106 is etched and the resist pattern 107 is transferred to form a mask. The barrier layer 105 and the quantum well layer 104 are etched by ion beam etching. The barrier layer 103 is etched by wet etching in a depth direction and, as the wet etching is also developed laterally, the wire widths of the barrier layer 105 and the quantum well layer 104 are narrowed. An Al0.3 Ga0.7 As buried layer 109 is built up by crystal growth over the whole surface by a molecular beam epitaxy method.

Abstract: PURPOSE:To determine three kinds of Chromogens of chyle, haemolysis and yellow from the same sample simultaneously, by measuring absorbances in a long wavelength region, in an intermediate wavelength region, and in a short wavelength region of a visual wavelength region. CONSTITUTION:Curves 20, 22 and 24 are absorption spectrums of a chyle reference liquid, a haemolysis reference liquid and a yellow reference liquid, which are diluted by a GOT measuring liquid, respectively.

The degree of the haemolysis is obtained based on the absorbance in the long wavelength region and the absorbance in an intermediate wavelength region (e.g., lambda18 and lambda19), where the effect of the yellow does not actually exist. The degree of the yellow is obtained from the absorbance in the intermediate wavelength region and the absorbance in a short wavelength region (e.g., lambda15 and lambda16).
