Filed: 1986-04-03
Abstract: PURPOSE:To obtain the titled crystals, economically by cooling an aqueous solution of acrylamide in a double-pipe or multitubular heat exchanger, in which the aqueous solution is passed through the inside of cooling pipes, made of stainless steel and electropolished and a refrigerant liquid is passed through the outside thereof. CONSTITUTION:An aqueous solution of acrylamide is cooled in a double-pipe or multitubular heat exchanger, in which the aqueous solution of acrylamide is passed through the inside of cooling pipes made of stainless steel and a refrigerant liquid is passed through the outside thereof, to crystallize the acrylamide. In the process, the cooling pipes are characterized in that the inside thereof is electropolished. The liquid flow velocity at the cooling heat transfer surface must be increased to carry out the cooling and crystallizing of a substance readily causing scale deposition, e.g. acrylamide. A multitubular heat exchange capable of increasing the heat transfer area is particularly preferred for the type of the cooler. The effect of the electropolishing seems to produce good results on a scaling phenomenon of acrylamide crystals by the change in surface conditions of the metal.

Title: Method of manufacturing semiconductor device
Inventor: YOKOZAWA AYUMI
IPC: H01L29/78
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To reduce the boundary level and to suppress the generation of electron trap, by performing heat treatment at a specified temperature range in the same furnace that an oxide film is formed. SOLUTION: After forming a gate oxide film on a silicon substrate, the heat treatment of it is performed in a fluoride gas atmosphere in the same furnace that an oxide film is formed. Activation energy that is obtained by a calculation is used and each reaction is assumed as an Arrhenius type. Upper limit temperature is approximately 80 deg.C where trap level density corresponds to Si-O density that is not bonded and the allowable upper limit of the density is 10<11> cm<-2> . Lower limit temperature is approximately 70 deg.C to suppress the density of an Si-H bond and an Si-OH bond that are not substituted by an Si-F bond to be 10<12> cm<-2> or less. When the setting temperature of the heat treatment is kept in the range of 700 to 800 deg.C and the heating is continued for 3 to 10 minutes, F is conducted into the boundary and the boundary level is terminated. Containment of F into an oxide film bulk is suppressed because of low temperature treatment. After that, N2 is introduced into the furnace and the substrate is taken out of the furnace.

Title: Array antenna
Inventor: MAYAMA TAKASHI
IPC: H01Q25/02
Filed: 1993-04-02
Abstract: PURPOSE:To uniquely determine an excitation distribution which can obtain a satisfactory pattern even in the case of a curved surface shape by determining the excitation distribution so as to form a pattern of a narrower null point interval than a null point interval of a desired excitation distribution in the case of a plane array. CONSTITUTION:Data of a position and a pattern of each antenna element 11-1n are read in, and the same Taylor distribution as the case of a plane array is given as an initial excitation distribution. In this case, with regard to the plane array and a circular arc arrangement array, when opening areas viewed from the beam direction are compared, respectively, the opening variations are given by COStheta, and (1+COStheta)/2, respectively. A null point of the plane array is already known. Therefore, with regard to the circular arc arrangement array, a null point is set in a position which becomes a narrower interval than a null point interval in the case of the plane array, and also, an excitation distribution is corrected so as to obtain this null point. Accordingly, a deviation of a radiation pattern generated on the opening surface is decreased, by which a side lobe level can be reduced.
