Title: Sodium recovering device
Inventor: SUZAKI KAZUTAKA
IPC: G21C19/31
Filed: 1993-12-02
Abstract: PURPOSE:To provide a Na recovering device allowing reutilization by providing a gas-liquid separating means separating a discharged object discharged from an overheater and an evaporator and containing liquid Na and a reaction product into a gaseous material and a liquid material. CONSTITUTION:When cracks are generated on heat-transfer pipes in heat exchangers such as an superheater 7 and an evaporator 8, the water and steam flowing in the pipes 10 flow into a liquid N around the pipes 10. The pressure in the heat exchangers rises, a pressure release plate 16 is broken, and the liquid Na and a reaction product in the heat exchangers are guided into a tubular gas-liquid separator 14. The Na or the like flowing into the separator 14 becomes a swirl current, a liquid and a solid collide with the inner wall of the separator 14 via the centrifugal force of the swirl current and are accumulated at the bottom section. The accumulated Na and reaction product are guided into a dump tank 19 when a drain valve 25 is opened. The liquid Na recovered in the tank 19 is circulated to the Na purifying device 21 of the secondary cooling system via an overflow tank 20, and it can be returned to the secondary pipe 6 after impurities are removed.

Abstract: PURPOSE: To provide a method for removing carbonyl impurities from esters, such as methyl acetate.  
     CONSTITUTION: An amino compd. which forms a water-soluble nitrogen-contg. deriv. by reacting with carbonyls is added to esters to separate the org. ester phase and the water-soluble deriv. phase and further the heavy duty impurities are further removed by distilling this ester phase, by which the esters, such as methyl acetate contg. the carbonyl impurities including the aldehydes are refined. The formation of the nitrile from the nitrogen-contg. deriv. is decreased by adding water to a distillation column or washing the aq. column bottom liquid of the distillation with water and the deriv. is further removed from the esters included in this column bottom liquid. The esters may be recovered by recycling the org. phase recovered from the column bottom liquid to the distillation.

Abstract: PURPOSE: To form pits or grooves more approximate to a rectangular shape than heretofore and to obtain a dense optical disk having a high CN and low error rate by executing a stage for bringing a positive type photoresist and aq. alkaline soln. into reaction prior to a stage for applying an alkaline developer. CONSTITUTION: The positive type photoresist 2 consisting of a novolak resin as a base resin and a naphthoquinone azide as a photosensitive agent is applied on a polished glass substrate 1 and is dried. This positive type photoresist is then exposed with musical tone signals by a laser beam 3 and is recorded with the pits. An exposed glass master disk 1 is mounted at a spin coater and is rotated and an aq. ethanol soln. 4 of a prescribed concn. is dropped for 30 seconds at a flow rate of 8 liter/h, by which an esterified layer 5 is formed on the surface of the exposed parts of the photoresist. After the aq. ethanol soln. 4 is dropped on the photoresist, the photoresist is developed by the alkaline developer 6 diluted to 1/1.5 with pure water, by which the exposed parts are removed and the pits 7 are formed.  As a result, the pit length and pitch width are made finer by 1/2 than the pit length and pitch width of the conventional CDs. The CD increased in density four times is thus produced.
