There is disclosed a novel flat heating surface type gas stove which is capable of heating a heating substance across a heat resistance glass at practically applicable heating efficiency, overcoming any inconvenience resulting from the exposure of flame and facilitating the cleaning of the gas stove. This gas stove 10 comprises a heat resistance glass top plate 12 which is disposed over a burner 15, wherein a gas-permeable porous body 40 is disposed below said top plate 12, and a space between said top plate 12 and a surface of said gas-permeable porous body 40 is assigned to a combustion space S. Combustion gas generated is designed to be discharged through said gas-permeable porous body 40. As high-temperature combustion gas passes through said gas-permeable porous body 40, radiant heat B is generated from the surface of said gas-permeable porous body 40. Since the heating substance 4 is heated by both of heat conduction and radiation, high heating efficiency can be achieved.

摘要:
A process for converting glycine to L-serine is effected by the use of an aqueous medium containing glycine and microbial cells of a mutant belonging to the genus Nocardia. The mutant is capable of converting glycine to L-serine and has no or lowered ability to decompose L-serine and/or a resistance to at least one metabolic antagonist selected from those of glycine, serine, methionine, glutamine, histidine, leucine, isoleucine, valine, purine, pyrimidine or folic acid. The L-serine is accumulated in the aqueous medium and is recovered therefrom.
摘要:
A pressure is applied by pressure means to a blood vessel from the outside, and gradually reduced, and the pressure resulting from movement of the blood pressure during the pressure reduction is converted by a pressure sensor into an electric signal. The converted output is differentiated twice, and it is detected that a first-polarity pulse, a second-polarity pulse and another first-polarity pulse are generated successively in the differentiated output waveform within a predetermined period of time. The highest blood pressure is obtained with the pressure of the pressure means at the moment of first detection of three such pulses, and the lowest blood pressure is obtained with the pressure of the pressure means when the above detection is no longer achieved. The measured values are recorded in a digital form and, at the same time, the converted output waveform is recorded.
