摘要:
A salt waste composed mainly of chlorides, which is generated from the step of a molten salt electrolytic purification in dry reprocessing of a spent metallic nuclear fuel, is reacted with boric acid at high temperature to convert the chlorides in the salt waste into oxides. The resulting oxides of the salt waste are easily vitrifiable, and a vitrification product is obtained by adding a vitrifying additive to the oxides, heat-melting the mixture to form a molten mixture and cooling the molten mixture.

A process of manufacturing the spark plug that includes a step in which a receiving die having an insertion hole and a taper portion is used, wherein a thread portion of the spark plug is inserted into the insertion hole and a seat portion of the spark plug is brought into contact with the taper portion, and a pressing force is applied to a rear end portion of a metallic shell of the spark plug so as to bend a rear end opening portion of the metallic shell, and to thereby form a crimped portion, whereby an insulator and the metallic shell are fixed together.

The present inventors discovered that the onset of galactosamine hepatopathy is suppressed by nutritional compositions comprising as essential ingredients: whey protein hydrolysates; lecithin and oils and fats high in oleic acid, which are able to improve the lipid metabolism; and palatinose having an insulin-sparing effect. Furthermore, the whey protein hydrolysate included in the nutritional compositions was found to suppress endotoxin-induced TNF-a and interleukin 6 (IL-6) production in macrophages.

A TiCl4 gas is supplied to a molten CaCl2 liquid held in a reactor vessel 6 through a raw material feed pipe 11, TiCl4 is reduced to produce granular metallic Ti by Ca melted in the CaCl2 liquid. The molten CaCl2 liquid in which Ti granules taken out downward from the reactor vessel 6 is mixed is delivered to a separation process 12, the molten CaCl2 liquid is heated in a heating vessel 15, and separation is generated by a difference in specific gravity, whereby the molten CaCl2 liquid 16 is located in an upper layer while a metallic Ti 17 is located in a lower layer. The metallic Ti 17 in the lower layer is taken out from a high-melting-point metal discharge port 18, and the metallic Ti 17 is solidified to yield an ingot. The molten CaCl2 liquid 16 in the upper layer is delivered to an electrolysis process 13 along with the molten CaCl2 liquid taken out from the reactor vessel 6, and Ca generated by the electrolysis and CaCl2 are returned into the reactor vessel 6. A separation and recovery method of the invention is applied to the separation process 12 in the above production process, and high-quality Ti or Ti alloy is efficiently separated and recovered from the CaCl2-containing molten salt with a small amount of energies.

A method for production of metal by molten-salt electrolysis is a method for production of metal by molten-salt electrolysis which is performed by filling molten salt of a metal chloride in an electrolysis vessel having an anode and a cathode, and a molten salt which reduces solubility of the metal in the molten salt is used.

A mixed molten salt containing CaCl2 and NaCl is held in the reactor cell 1 at a temperature not more than 600° C. TiCl4 which is of a Ti raw material is introduced into the reactor cell 1 while Na is introduced into the reactor cell 1. Na introduced into the reactor cell 1 is replaced by Ca, Ca is dissolved in the molten salt, Ca reduces TiCl4 introduced into the reactor cell 1, and thereby Ti particles are generated. The generated Ti particles are introduced to a separation cell 2 along with the molten salt, and the Ti particles and Na are separated from the molten salt. The residual molten salt is introduced to an electrolytic cell 3 to generate Na by high-temperature electrolysis at the temperature more than 600° C. The generated Na is returned to the reactor cell 1 to replenish Na consumed in the reactor cell 1. The highly reactive Ca is not directly handled, and Na which is easy to handle is used in a circulating manner. Therefore, the Ti or Ti alloy can economically be produced by Ca reduction.
摘要:
A diaphragm is uniformly and finely deformed by compressed air supplied from an electro-pneumatic regulator, so that test fluid is supplied in conformity with the deformation of the diaphragm. In this way, a flow quantity of the test fluid supplied from a fluid supply device to a measurement passage is accurately adjusted. Therefore, an accuracy of a flow accuracy check device is improved, and a leakage measurement accuracy at the time of measuring a leakage from a fuel injection valve with a flow measurement apparatus is improved. At the time of measuring the leakage from the fuel injection valve, the diaphragm is stopped at a balanced position where a force of the air supplied from the regulator and a resilient force of the diaphragm is balanced. Therefore, a change in a volume of the measurement passage, which would be otherwise caused by movement of the diaphragm, does not occur.

According to one embodiment, a vibration sensor senses a vibration level of a cabinet of an information processing apparatus as a first vibration level. A first determination unit determines whether a storage device is in operation in a specific state where audio is output from a speaker. A second determination unit determines whether the first vibration level exceeds a second vibration level when the storage device is in operation. A volume control unit controls the volume of the audio output from the speaker to lower the volume when the first vibration level exceeds the second vibration level.
