摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a photothyristor where each ignition sensitivity is uniform. SOLUTION: A photothyristor where each ignition sensitivity is uniform can be obtained by measuring the sheet resistance of the p-type base layer at the section to serve as a light receiving part, and forming the n-type emitter layer 8 at a light receiving part by ion implantation under the conditions of a concentration file geared to the value, after forming a p-type base layer 3. This way, the n-type emitter layer 8 at the light receiving part is made by ion implantation high in controllability, so the ignition sensitivity of each photothyristor can be made uniform.

摘要： PROBLEM TO BE SOLVED: To facilitate positioning a semiconductor material and preventing its rotation and improve reliability by providing rotation-preventive pins engaging with an external electrode that is not in contact with the semiconductor material. SOLUTION: A semiconductor material 31 has a plastic edge protector 12 with a projection 12a that engages with recesses 13a provided in an insulating ring 13 for securing the semiconductor material. The engagement of the projections 12a with the recesses 13a serves to position the semiconductor material with respect to the insulating ring and prevent its rotation. On the other hand, the insulating ring is prevented from rotating by means of pins 14 that seat at one end in recesses 13b in the underside of the insulating ring 13 and at the other end in recesses 2a opened in an external electrode 2, and thus the semiconductor material is prevented from rotation.

摘要： PURPOSE:To analyze sodium ions in the feed water of a power plant with high accuracy. CONSTITUTION:Oxygen is fed to the sample water collected from the feed water of a power plant by an oxygen feeding device 1, and ultraviolet rays are radiated to decompose ammonia in the sample water. Cations in the sample water are concentrated by a concentrating device 3, and sodium ions in the sample water are analyzed by a cation ion chromatograph 4. Since the sample water is oxidation-treated, the ammonia concentration in the sample water is reduced, the peak of ammonia ions and the peak of sodium ions are separated, and the sodium ions can be analyzed with high accuracy.

摘要： PURPOSE: To control the rate of feeding of substrate in the aerated cultivation of baker's yeast so as to conduct the feed of the cultivation substrate at the optimum rate, by detecting the production of ethanol from the data obtained by the measurement of the feed gas flow and the exhaust gas flow.
CONSTITUTION: The feed gas flow rate and the exhaust gas flow rate are measured continuously during the cultivation by the feed gas flow meter 5 and the exhaust gas flow meter 6, respectively. The measured data are inputted to a comparing means 7, in which the ratio of the flow rates is calculated, and the comparative relationship of the rates is displayed by the displaying means 8. When the exhaust gas flow rate is larger than the feed gas flow rate, it is supposed that ethanol is produced by the excessive feed of the substrate, and the substrate feed rate is reduced by operating the substrate feed rate controlling means 3. On the contrary, when the exhaust gas flow rate is smaller, the substrate feed rate is incresed. The control can be performed automatically, by electrically connecting the comparing means with the substrate feed rate controlling means.
