Abstract: To utilize fish catch microdata obtained on a daily basis at fishing grounds for fresh fish, and to rapidly and accurately transmit the fish catch information to the various consumer markets via a computer communications network, so as to promote distribution and commercial transactions that rapidly adjust to changes in supply and demand, and so as to rationalize and stabilize the market price of fresh fish, while preventing a decline in the degree of freshness of the fish. Having fisheries input to a server fish catch microdata via a computer communications network, converting this data to a database and storing it on a server, so that when a fishery, distributor, consumer, or the like seek fresh fish information, they are asked to input to the server the selection conditions for the desired information via a computer communications network, and the fresh fish information conforming to these conditions is read from said database, and transmitted to the party desiring the fresh fish information.

Abstract: The present invention relates to navigation of an autonomous vehicle capable of autonomously tracking a route toward a destination.

Abstract: A magnetomeasuring apparatus includes a cooling vessel holding a plurality of magnetic field sensors and a coolant. The magnetomeasuring apparatus comprises a sensor support with the plurality of magnetic field sensors removably mounted thereon, and a fixing device for removably fixing the sensor support with the plural magnetic field sensors mounted thereon to a measuring surface of the cooling vessel. An opening of the cooling vessel is larger than the measuring surface. The magnetomeasuring apparatus has a small opening so that the apparatus has a small total amount of heat intruding the vessel.

Abstract: A composite digital network including an integrating circuit, a summing circuit and a coefficient circuit is formed as an integrated circuit that provides a selected one of digital arithmetic circuits that perform different arithmetic operations depending upon coefficients of the coefficient circuits. A plurality of units of such composite digital networks may be connected in rows, columns or layers to provide an expanded network. In a method of producing such a composite digital network, basic digital arithmetic circuits that respectively correspond to various types of basic analog arithmetic circuits are defined based on Kirchhoff's rules, for example, and these basic digital arithmetic circuits are coupled to each other via a coefficient circuit to thus provide a generic digital arithmetic integrated circuit.

Abstract: Apparatus for measuring weak magnetic fields includes a cryogenic vessel CR having a domed bottom D for accepting a human head, a plurality of magnetic sensor units 10 mounted upright on the inner surface of the bottom D of the cryogenic vessel CR, an interface device 20 for receiving output signals of the magnetic sensor units 10 through respective lead lines 4, a data processor device 30 for analyzing the output signals of the magnetic sensor units 10 to specify magnetic fields spread in the ambient space about the human head and calculating the activity of a brain B from the magnetic fields, and a display device 40 for displaying the brain activity. Each of the magnetic sensor units 10 is fed along its guide line G through a small opening OP of the cryogenic vessel CR and mounted upright on the bottom D. As the opening OP of the cryogenic vessel CR is relatively small, the evaporation loss of a coolant in the cryogenic vessel CR is minimized and the running cost of the apparatus will be decreased.

Abstract: An educational mechatronics apparatus comprises a plurality of circuit boards respectively corresponding to blocks appearing on a block diagram of an automatic control system, the circuit boards being arranged along the direction of signal transfer, each of the circuit boards being provided with circuit components including input and output terminals and having a center area and opposite end portions, and a transparent protective plate covering the center area of the circuit board to inhibit a learner to touch the circuit components other than the input and output terminals located in the end portions of the circuit board. The input and output terminals located in the center portion of the circuit board are wired in advance of assembly of the apparatus, and the input and output terminals located in the end portions are adapted to be wired for learning by leads.
