摘要:
The present invention provides a vibration measurement method and apparatus capable of accurately measuring displacement even if the displacement is very small. The vibration measurement method according to the present invention comprises: a laser beam application step (step S1) for applying a laser beam of a first wavelength to an object to be measured; a beat wave generation step (step S2) for mixing a laser beam of a second wavelength which is different from the first wavelength and the return beam reflected from the object to be measured; and a vibration information output step (step S3) for outputting the beat wave thus generated as a vibration information of the object to be measured.

The invention relates to a method for producing molten salts and their mixings, using an extruder. The starting materials are melted and reacted and the products of the reaction are then guided via a column with alkali salt.
摘要:
A new process for producing calcium chloride and other metal halides from the carbonates, bicarbonates, oxides of these metals. The process utilizes the discovery that hydrogen halides, when used in a true or conventional fluidizing medium in shallow beds of the aforementioned solids at moderately elevated temperatures in a continuous counter current process results in the conversion of the metal carbonates, bicarbonates, and oxides, into metal halides and carbon dioxide gas and/or water vapor. The process is carried out in a series of true or conventional fluidized beds preferable but not necessarily arranged in a vertical configuration so that the solids flow downward due to the fluidized process and the hydrogen halides flow counter currently in an upward direction producing metal halides at the bottom and pure carbon dioxide gas and/or water vapor at the top.
