摘要： PROBLEM TO BE SOLVED: To perform a calibration operation and the control of maintenance data according to a pressure transmitter at the field occasionally for rationalization and saving power, by incorporating a pressure calibration control unit and a communication unit in a handy personal computer in a portable structure, and automatically performing a calibration operation while operating the units at the field. SOLUTION: An automatic pressure-adjusting device 1 incorporates a communication unit 12. A communication unit 17 of the handy personal computer 2 communicates, for example, calibration data and measurement values with the automatic pressure-adjusting device 1. A pressure calibration control unit 18 of the handy personal computer 2 takes out current and past calibration data of a pressure communication equipment 3 being retained in a calibration database 20. Pressure being applied by a calibration control part 19 is determined, and a set pressure is transmitted to the automatic pressure-adjusting device 1 via the communication unit 17, thus setting calibration data on the spot and retaining data after calibration operation without returning to a measurement room for the pressure transmitter 3 being mounted to the field.

摘要： PROBLEM TO BE SOLVED: To provide a loop check system for simplifying a loop check work in a plant facility. SOLUTION: A loop check system is provided with a loop check device 40 which can be connected with a sensor unit 101 which measures the physical amounts of an object 100 to be inspected, portable information terminal 20 which can be connected with the loop check device 40, and mobile communication terminal 30 as the communicating part of the portable information terminal 20. The loop check of the object 100 to be inspected by the loop check device 40 is operated through bi-directional information transmission between the portable information terminal 20 and a center computer at a remote place through a mobile communication line 3.

摘要： PROBLEM TO BE SOLVED: To provide a system and a method for supplying energy to a local community, in which residents can approach problems of energy and environment in cooperation with a local community.
SOLUTION: Neighborhood homes 1, 2, 3 in a local community organize a neighborhood self-governing body for building up a closer corporation in energy utilization. They connect respectively to a neighborhood cogeneration (N.C.G.) 10 via lifeline to receive supply of heat and electric power. Heat is supplied in a form of high temperature water through a small diameter pipe. Each of the homes 1, 2, 3 has heat storage apparatus, and the stored heat is supplied to a high heat-load. Surplus electric power is sold through an energy- service company 32, and the profit is returned to respective homes 1, 2, 3. Thus, homes 1, 2, 3 each keep in mind the energy-saving way of life.

摘要： PURPOSE:To establish a stable supplying system by controlling supply pressure by predicting the demand of a natural gas at every 10-30sec. CONSTITUTION:A gas supply prediction control part 10 in this invention is constituted of a prediction model 11 and an evaluation part 12. The prediction model 11 is a model to predict the future state (y) of the system based on a manipulated valuable u1 which represents the state of the system, measurable disturbance u2, and appropriately presumed unmeasurable disturbance (d) by using a step response coefficient. Also, as a transfer function, the one in which the transfer functions of an LNG caburettor 4 and LNG flow control valves V11 and V12 are approximated with first-order lag is used. In such a way, a prediction model can be realized in practical use even in a computing element with the standard of a microcomputer.
