IPC: B01J27/10
Filed: 1984-08-24
Abstract: PURPOSE:To produce the titled compound in high yield, in shortened reaction time, by circulating a reaction mixture in the order of the absorber of hydrogen chloride catalyst, the reactor and the dehydrator, in the esterification reaction of lysine dihydrochloride with ethanolamine hydrochloride. CONSTITUTION:Lysine dihydrochloride and ethanolamine hydrochloride are introduced at a molar ratio of 1:(0.5-10), preferably 1:(1-3) into an absorber such as a column packed with Rasching rings to effect the absorption of hydrogen chloride, and then supplied to a reactor and reacted at 100-130 deg.C and 0-1kg/cm<2>G pressure. The reaction mixture is dehydrated in a wetted-wall column dehydrator at 110-140 deg.C and <=30mm.Hg pressure to obtain the objective compound. Preferably, the reaction mixture is circulated through the absorber and the reactor at a rate to circulate once 10-20min, and 1/3-1/10 of the circulating mixture is branched through the dehydrator and returned to the absorber or the reactor, thereby carrying out the reaction and dehydration in parallel.

Title: Method for coating converter with slag
Inventor: INATOMI TOSHITAKA
IPC: C21C5/44
Filed: 1984-08-24
Abstract: PURPOSE:To increase the amount of slag stuck to a converter by coating and to prolong the life of the converter by adding a modifier to slag remaining in the converter and coating the surface of the inner wall of the converter with the slag by means of a lance for blowing oxygen.

Inventor: TANIGUCHI KOTARO
IPC: A47J27/00
Filed: 1990-07-03
Abstract: PURPOSE:To provide a microwave oven cooking bag also serving to preserve food which has excellent heat insulation and in which there is no odor transfer to food and no adsorption of food odor components to a film by forming the bag with a specific polybutylene terephthalate resin film. CONSTITUTION:A microwave range cooking bag comprises a polybutylene terephthalate resin film of relative crystallinity of 10 % or higher as measured by X-ray diffraction in the atmosphere of 23 deg.C and 50 % RH and under a diffraction angle 2theta=5-45. A film satisfying the above conditions, particularly an inflation film has excellent heat insulation and further has properties of a barrier against gases, of keeping odor, and of sealing heat, and hence is preferable. In the case of the relative crystallinity of 10 % or lower there is formed much blocking upon formation of the film to make difficult the film formation itself, and to result in deteriorated heat insulation. A film prepared by an inflation formation process using polybutylene terephthalate resin has high tensile strength and excellent in a barrier property against gases and is manufactured inexpensively.

Title: Linear/float conversion circuit and musical sound synthesizer using thereof
Inventor: KUNIMOTO TOSHIFUMI
IPC: G10H1/00
Filed: 1990-07-04
Abstract: PURPOSE:To synthesize high-quality musical sounds by using a linear/float conversion circuit which converts a waveform value into a value of a floating- decimal point system having a smaller number of bits and, at the same time, is contrived to reduce the waveform distortion caused by an error produced at the time of the conversion. CONSTITUTION:An initial waveform given to an adder 1 is repeatedly circulated through a closed loop from and to the adder 1 through an adder 5, linear/float converter 6, delay circuit 2, linear/float converter 10, filter 3, and multiplier 4 and, as the circulation is repeated, the waveform gradually becomes smaller. Even when an error occurs in the course of converting a waveform value by means of the converter 6, the error is added to the output waveform value of the adder with a time lag of one sample period. Therefore, adverse influences to musical sounds associated with the above-mentioned conversion into values of a floating-decimal point system can be reduced substantially and high-quality attenuated sounds can be obtained. Moreover, when noise is added to the output of a delay circuit 9, the audible noise level can be reduced.
