  • Patent number: 9990415
    Abstract: An information processing device processes target information described using identifiers formed from a symbol, a product operator that joins together factors containing one or more of the identifiers and thereby forms a string of ordered factors, and a sum operator that joins together terms containing one or more of the factors and thereby forms an expression that is a combination of the terms. Also, information processing device includes a dividing unit that divides the target information into a plurality of terms at a predetermined position; and a transmission unit that associates positional information with at least any of the factors contained in the terms resulting from the division and causes each of the terms resulting from the division to be held in any of a plurality of server devices, where the positional information contains an occurrence sequence of the terms in the target information and an occurrence sequence of the factors in the terms.

  • Patent number: 9609890
    Abstract: A technique for highly efficient production of ?-amino butyric acid (GABA) using mochi barley of the group of mules barley, as a raw material. The technique converts glutamic acid into GABA due to the glutamate decarboxylase contained in the mochi barley so GABA-mochi barley grains and GABA-mochi barley bran and GABA-containing bran supernatant can be produced highly-efficiently by mixing mochi barley grains, which have been polished in a barley milling device to an extent of 2% or more and less than 20%, with a glutamic acid solution, which has a concentration of 0.1 to 3% and a pH value of 2 to 9, and soaking the barley in the solution at room temperature for 1 hour or more to overnight or, after soaking in the solution similarly for 1 hour or more to overnight, draining the barley grains, and keeping it overnight at room temperature.

  • Patent number: 7284902
    Abstract: A mixing tube is provided, including first and second mixing passages, each of which include a plurality of elements connected in series and having a sectional shapes that change continuously. Multi-component materials pass through the first and the second mixing passage, repeatedly dividing and aggregating the materials in a passing process. The first and the second mixing passages are formed by a first outer frame member, a second outer frame member, and a partition member. The first and the second mixing passages repeatedly divide and aggregate due to the hole portions in the partition member, and with this mixing tube, the materials to be mixed pass trough the mixing passages by continuing and manually squeezing the mixing tube from the inlet port to the outlet port of the first and the second mixing passages, and sufficient mixing can be obtained.

  • Patent number: 6332707
    Abstract: An object of the present invention is to provide a kneader capable of improving both of its kneading and mixing functions, irrespective of a horizontal arrangement or a vertical arrangement, with a comparatively simple design not to degrade the workability thereof. To attain the object of the invention, a kneader adapted to knead an object material by passing it through a plurality of irregular passages (22, 23), each having a sectional shape varied, from an inlet port thereof toward an outlet port thereof, comprising a kneader body (20) having a material supply port (20a) at one end thereof, a material discharge port (20b) at the other end thereof and a plurality of irregular passages communicating with the supply port (20a) and the discharge port (20b), and supply means (10) for supplying the object material to the kneader body. The sectional shape of each of the irregular passages (22, 23) of the kneader body (20) is varied progressively from an inlet port (22a) toward an outlet port (22b).

  • Patent number: 5915790
    Abstract: A cutterhead is supported at the front part of a main frame so as to incline at a specified angle with respect to a vertical plane. The main frame includes (i) a roof support disposed at a position corresponding to where a reaction force acts in the direction of the periphery of a tunnel against a force caused by rotation of the cutterhead, and (ii) a pusher for pushing the roof support toward the cutterhead resisting the reaction force.

  • Patent number: 5843350
    Abstract: A method of easily consecutively manufacturing a layered structure with the same or different kinds of materials superposed in a plurality of layers, is attained by a simple mechanical method. The layered structure manufacturing method is embodied by use of a shaping apparatus having a unique construction. The shaping apparatus includes a plurality of irregular passageways disposed in a side-by-side relationship in the same direction, wherein sectional configurations of the irregular passageways continuously vary from inlets thereof toward outlets, and the irregular passageways are superposed on each other at the outlets. An apparatus body as a principal portion of the shaping apparatus may be constructed by connecting a plurality of elements in series, which are internally formed with the irregular passageways. Materials to be shaped, which exhibit a fluidity or plasticity, are fed into the inlets of the irregular passageways in the shaping apparatus.
