Abstract: An arbitrary function generating circuit incorporating an analog multiplier, amplifier, and frequency multiplier to construct a nonlinear analog circuit equivalent to a generalized Lotka-Volterra equation for performing high-speed calculations.

Abstract: The present invention relates to wheat starch which reaches the peak viscosity at 75 to 85.degree. C. and whose amylose content is 0.8% or more and 2.5% or less, as well as to foods containing the same. Wheat flour which is of glutinous properties and excellent in viscosity stability is provided.

Abstract: A process and apparatus for producing a frozen product or a freeze-dried product therefrom of, in particular, a material susceptible to denaturing due to existing enzymes, oxygen and heat, such as living organisms, organic compounds, vegetables, foods, fruits, drugs, biological samples, fodders and industrial raw materials while preserving the original qualities and properties, by recourse to a technique including the steps of mixing and crushing the material to be processed together with dry ice to thereby attain freezing of the material while replacing of the surrounding atmosphere by the thereby liberated carbon dioxide gas.

Abstract: An apparatus and a method for analyzing the physiological state of a sample of a living organism of eucaryotes and procaryotes, e.g.

Abstract: An apparatus and a method for magnetic resonance imaging of a sample to be inspected without the sample chamber to be taken out of the apparatus under omission of renewed operation of tuning and shimming on each test, by excluding transmission of any vibration of the static and the gradient magnetic field generating elements to the detection unit, which includes supporting, within a hollow core space (4) in static and gradient magnetic field generating elements (1) and (2), a detection unit (10) composed of a sample chamber (11) and an RF-emission-reception set (12) including an RF coil (13) by a support member (14), such that they are isolated from said static magnetic field generating element (1) and from said gradient magnetic field generating element (2); performing the sample exchange by guiding the sample (15) into said sample chamber (11) via a sample transfer line (18) by making use of a vacuum and compressed air; building up a gradient magnetic field while the sample chamber (11) is charged with the

Abstract: A bioreactor which and be used with substrates which are difficult to attain sufficient dispersion is made up of a reaction vessel 1 having a reaction chamber 2 surrounded by a water jacket 3 for maintaining a predetermined constant temperature. The reaction chamber 2 is provided in the vicinity of the inner wall surface 2a of the reaction vessel 2 with a plurality of upright screws 6 and 7 in an adjoining relationship to each other, each screw having a screw thread or a helical fin 6b, 7b of reverse turning sense with each other so that the reactor vessel contents are subjected to a convectional flow induced by the rotation of the screws in the reverse sense to each other by a gearing 14, 15. The substrate therein is subjected to a uniform agitation and to a milling and sieving actions in the portion 13 where the fins of the screws face each other, before the reaction product is removed by a screw conveyer 25.
