A manufacturing method of a sintered ceramic body mixes barium silicate with aluminum oxide, a glass material, and an additive oxide to prepare a material mixture, molds the material mixture and fires the molded object. The barium silicate is monoclinic and has an average particle diameter in a range of 0.3 μm to 1 μm and a specific surface area in a range of 5 m2/g to 20 m2/g. The aluminum oxide has an average particle diameter in a range of 0.4 μm to 10 μm, a specific surface area in a range of 0.8 m2/g to 8 m2/g. A volume ratio of the aluminum oxide to the barium silicate is in a range of 10% by volume to 25% by volume.

The present invention relates to a process for producing D-lactic acid and L-lactamide, comprising allowing a culture broth of a microorganism capable of asymmetric hydrolysis of DL-lactamide belonging to the genus Alcaligenes, Pseudomonas, Agrobacterium, Brevibacterium, Acinetobacter, Corynebacterium, Enterobacter, Micrococcus or Rhodococcus, the microorganism itself, a material obtained therefrom or an immobilized material thereof to act on DL-lactamide, and recovering the resulting D-lactic acid and the remaining L-lactamide. The present invention enables sufficient production of D-lactic acid and L-lactamide by the present microorganism.
摘要:
There is provided a thermal transfer sheet that, by virtue of flexibility and heat resistance imparted by a primer layer constituting the thermal transfer sheet, is less likely to be broken even upon exposure to a high level of thermal energy and is highly suitable for high-speed printing. The thermal transfer sheet has a thermally transferable colorant layer provided on one surface of a base material sheet, and a heat-resistant slipping layer provided on the other surface of the base material sheet through a primer layer. The primer layer contains at least a polyvinyl alcohol resin and a crosslinking agent.
