    摘要： A brake disk producing method, comprising a periphery pressing step for forming an outer peripheral shape (5) of a rotor plate (2) into a peripheral shape having recesses and ridges (5a, 5b) repeated in a radial direction, and a chamfering step for forming a chamfered surface (6) by pressing, against a corner portion (2d) on an outer peripheral edge of the rotor plate (2), a die (7), and a brake disk made by the method. Accordingly, it is possible to improve heat radiation capability, reduce the weight and moment of inertia, improve safety in handling, and suppress increase in production costs. Furthermore, by forming the chamfered surface (6), the amount of wear of a brake pad pressed by the brake disk (1) can be reduced, and durability of braking performance can be maintained or improved.

    摘要： A transistor gate structure that is free from notches is formed by using a hard mask. The hard mask has a bilayer structure of a BARC (bottom antireflective coating) over a silicon dioxide layer. A photoresist layer is formed over a portion corresponding to the gates. A first etch forms the gate structure. Following removal of the photoresist, a second etch completely removes the BARC. The silicon dioxide layer can be removed by a subsequent wet etch with HF.

    摘要： Amino acid fermentation is conducted by fermenting using bacterial cells in a culture medium in a fermentor and separating fermentation solution withdrawn from the fermentor into a solution containing the bacterial cells and a solution not containing bacterial cells by a cell separator, the solution containing the bacterial cells being circulated from the cell separator to the fermenter by a circulating device to perform amino acid fermentation continuously, and bubbles being removed from the fermentation solution by a bubble separator before the fermentation solution is fed to the circulating device and the cell separator.

    摘要： Cells having enzyme activity, and the enzyme activity thereof, are preserved for a prolonged period of time, as a suspension of microbial cells or as a suspension of immobilized cells in particles, in an aqueous medium that is a neutral or weakly basic aqueous solution of inorganic salts, having a molarity ranging from 100 mM to the saturation concentration of the inorganic salts. Preferably, the microbial cells are cells containing the enzyme, nitrile hydratase or nitrilase, such as Gordona terrae or Rhodococcus rhodochrous, and the inorganic salts are phosphates, borates, sulfates, sulfites or hydrochlorides. The present invention provides an industrially useful method for preserving a large quantity of cells or immobilized cells in particles having nitrile hydratase or nitrilase enzyme activity for a prolonged period of time (e.g., 300 days) without cell lysis or enzyme deterioration even at room temperature. The present invention also renders possible a sharp reduction in labor and cooling cost, which are necessary in the conventional preservation process.
