Title: Purifying method of benzaldehyde
Inventor: DEGUCHI TAKASHI
IPC: B01J31/00
Filed: 1980-05-12
Abstract: PURPOSE: To purify crude benzaldehyde containing impurities having boiling points close to one another, by the three steps of reacting the benzaldehyde with an aliphatic polyhydric alcohol in the presence of a catalyst, distilling the reaction mixture to remove impurities, and hydrolyzing the resultant acetal and subjecting the formed benzaldehyde to the azeotropic distillation with water.  
     CONSTITUTION: Crude benzaldehyde containing compounds having boiling points close to one another obtained by the oxidation of toluene or the hydrolysis of benzal chloride is reacted with a 2W6C aliphatic polyhydric alcohol (preferably ethylene glycol or propylene glycol) in the presence of a catalyst, e.g. p-toluenesulfonic acid, and the reaction mixture is then distilled to give an acetal. The acetal is then hydrolyzed, and the resultant benzaldehyde is subjected to the aceotropic distillation and distilled off with water.  
     EFFECT: The aliphatic polyhydric alcohol is reusable. The both reactions can be carried out in the presence of the same catalyst in the same reaction vessel.

Moreover, a second side plate body 13 is fixed to a cylindrical body 11 as to apply pressure in the winding axial direction of the coil 20 at a point in time when winding of the whole layers of the superconductive coil 20 is completed. Accordingly, friction of the superconductive coil in the winding axial direction can be lightened remarkably, and because the superconductive conductors move being unified in one body in regard to electromagnetic force in the diametrical direction being disabled to move independently one piece by one piece, friction to the direction thereof can be lightened sufficiently. Therefore, the superconductive condition can be held stably.

Filed: 1991-03-28
Abstract: PURPOSE:To reduce a short circuit defect caused by a method wherein an Inconel layer is formed on a constantly elastic material substrate composed of elinvar and a piezoelectric thin film is formed on it. CONSTITUTION:An Inconel layer 2 is formed between a constantly elastic material substrate 1 composed of elinvar and a piezoelectric thin film 3. Since constituent elements of Inconel arm similar to those of elinvar, the close contact property of Inconel is excellent with reference to elinvar. In addition, the close contact property of Inconel is excellent with reference to the piezoelectric thin film 3 which is constituted of a ceramic such as, e.g. ZnO or the like. In addition, Inconel is known a heat-resistant alloy, and it is hard to oxidize even in an oxidizing atmosphere, e.g. at 700 deg.C. Consequently, when the Inconel layer 2 is used as an intermediate layer, the close contact property of the piezoelectric thin film 3 with the constantly elastic material substrate 1 composed of elinvar can be enhanced, and it is possible to restrain the piezoelectric thin film 3 from being stripped or cracked. When it is used as a piezoelectric element, it is possible to reduce that a short circuit defect is caused.

Abstract: PURPOSE:To make a circuit for feedback-control of an x-ray tube voltage have a simple structure and capability of controlling the x-ray tube voltage highly stably. CONSTITUTION:The output of a tube voltage setting circuit 9 and the output of a voltage divider 7 which detects the voltage applied to an x-ray tube 6 are compared with each other by a comparator 8A, the lower one out of the set value and the detected value is outputted, this output is inputted in a proportion, differentiation, integration element 8B so as to eliminate any vibration component, and the resulting output is inputted in a comparison-selection circuit 11. A signal, which rises exponentially as time passing, from an exponential function generating circuit 10 is inputted in the comparison-selection circuit 11 and compared with the output of the element 8B and the lower one of them is outputted to a tube voltage controlling unit 3 as a control signal. Consequently, the voltage alteration rate at the time when the x-ray tube voltage reaches the set value can be lowered and stable control with little vibration can be carried out. Since the control voltage rises exponentially, the time until it reaches the set value can be shortened. Also, the structure can be simplified.

Title: Fluidized bed combustion system
Inventor: ASAI MINORU
IPC: F27B15/10
Filed: 1982-04-20
Abstract: PURPOSE:To enable completion of combustion within a fluidized bed even if a combustion rate is high and the height of the fluidized bed is low, by conducting the formation of the fluidized bed and a combustion through jetting of an air- fuel mixture after mixing the air and fuel by means of diffusing pipes. CONSTITUTION:After fuel through fuel pipes 7 and the air through air pipes 9 are mixed by diffusing pipes 4, the mixture is fed in a fluidized bed 2 through jet nozzles 5, whereby a fluidizing medium is fluidized by the mixture fluid and simultaneously is burnt with the aid of the high temperature heat from the fluidizing medium, and the combustion gas heast the fluidized medium as it ascends. In which case, the fuel and the air are previously mixed, and thereby a smooth combustion takes place. This permits the effective transfer of the heat being generated during combustion to the fluidizing medium while preventing the combustion of a free board 10 to allow the increase in a radiant heat. Further, this method enables to reduce the thickness of the fluidized bed 2.
