摘要： PURPOSE: To miniaturize a device and improve reliability at the time of power stoppage by providing a charger which charges a secondary battery through rectifying current of a commercial AC power source, and supplying power from the secondary battery to a motor through a variable voltage/variable frequency inverter. CONSTITUTION: Three-phase ac current from a three-phase commercial AC power source 11 is supplied to a line 15 through a braker 12, a line 13, and a switch 14. It is subjected to rectifying by means of a charger 17 through a braker 16, for float-charging a secondary battery 18. At the time of power stoppage, a common contact 25 of the switch 14 is conducted to an independent contact 24. When an operator sets ON an operation switch 1R, a coil 1RL is energized, and a starting switch MC1R is conducted. A timer 29 senses a conduction state of the switch MC1R. After a specified time passes, a trigger signal is supplied to an inverter 21. Voltage and frequency are highered, and kept constant afterward. A valve body of an electrically driven valve 1 is driven in a closing direction by means of an induction motor M1.

摘要： PURPOSE:To realize the automatic detection of the correct net coking time in a coke oven by detecting the start of coal charge and the termination of the coking period from information on the temperature of carbonization gas and calculating the net coking time from these results. CONSTITUTION:A lid 6 capable of undergoing an angular displacement around a horizontal axis by means of a hinge 7 is provided on the upper end 5 of a vertical duct 4 made of a refractory, installed on the top 3 of a carbonization chamber 1. A dry main 12 is connected to the side wall at the upper part of the vertical duct 4 through a connecting tube 9, a curved tube 10, and a connecting tube 11. A valve 13 having both a valve body 14 capable of undergoing an angular displacement around an axis 14 and an operating rod 16 is provided in the lower part of the tube 10, and a nozzle 17 is provided on the radially outward peripheral wall of the tube 10. A thermocouple 18 is buried in the refractory of the vertical duct 4 to detect a peak temperature at the last stage of carbonization. The net coking time is then obtained by an arithmetic operation.

摘要： PROBLEM TO BE SOLVED: To continuously monitor a subject extended to one direction by synthesizing a picture obtained by image picking-up a subject having a longitudinal length, and scroll-displaying it along a longitudinal direction of a subject on a display device. SOLUTION: The picture signals of a subject 28 image picked-up by each image pickup means 22a-22e are transmitted through a cable 23 to a picture processor 24. A picture processing device 24 fetches a picture signal transmitted from each image pickup means 22a-22e, operates a synthesizing processing based on an identification mark 30, converts it into a synthetic screen signal, and transmits it to a controller 25 and a storage device 26. The controller 25 converts it so as to be scroll-displayed on a display device 27. Thus, the picture signals outputted by each image pickup device 22a-22e which image picks-up the subject 28 can be synthesized, and the synthetic pictures linked in the longitudinal direction of the subject 28 can be scroll-displayed.

摘要： PURPOSE:To efficiently execute maintenance and to improve reliability by remotely monitoring and automatically diagnosing the operation situation of a co-generation equipment in plural customers by means of various machine type constitution. CONSTITUTION:In the co-generation equipment as a customer equipment 8, various kinds of data showing the operation situation are collected. Data are sampled at every minute and are added up at every hour. Added up data are collected as daily report data for 24 hours once a day, and they are transmitted to a center-side system 2A. A light fault set point is provided and data for one hour is immediately transferred as abnormal data of a light fault when the fault occurs. When a serious fault by which the customer equipment 8 trips occurs, high speed sampling data provided for a different system is immediately transferred. A fault diagnosis system 3 which is online-connected with the center- side systems 2A and 2B by 'Ethernet' 4 loads an expert system, and remotely monitors/automatically diagnoses the customer equipment 8.

摘要： PROBLEM TO BE SOLVED: To effectively utilize the power generating ability of a nonutililty generation facility while system interconnection operation is made so that no reverse power flow can be generated to commercial power supply. SOLUTION: The controller 33 of a nonutility generation facility 21 controls the generated electric power from a synchronous generator 30 so that the receiving power set by means of a receiving power setter 40 can become coincident with the measured value of electric power supplied from a commercial power source 33. The receiving power is predicted from patterns set in a receiving power time pattern setter 42 and a maximum instantaneous power decreasing pattern setter 43 and selected by means of a high selector 44. In a time zone in which the load power is low or the fluctuation of the load power is small, the availability of the facility 21 can be increased by receiving the receiving power.

摘要： PURPOSE:To provide a city gas pressure regulating device which copes with variation in gas demand in a short time, and which can effectively recover energy. CONSTITUTION:An expansion turbine 13 and bypass governors 14a, 14b, 14c are provided between an intermediate pressure A line 11 and an intermediate pressure B line 12. Gas at a lowest flow rate FG1 which gives a stable operation flows through at least one bypass governor 14a. When the gas flow rate F1 in the intermediate pressure B line 12 is larger than the sum of FG1 and FSET lowest value, the corresponding quantity of city gas is fed into the expansion turbine 13 as an expansion turbine gas flow rate F2 by means of a flow control device 19. In the expansion turbine 13, energy is recovered as a power when the pressure is decreased from the pressure P1 of the intermediate pressure A line 11 to the pressure p2 of the intermediate pressure B line 12 for rotating a generator 20. Further, the city gas can be heated also at the inlet side of the expansion turbine 13 so as to increase the recovery power, and a low temperature heat can be recovered from the city gas which has been cooled, at the outlet side of the expansion turbine 13.
