摘要： PURPOSE:To attain stable and sure communication by providing a specific transmitter and a specific receiver respectively to the system and to attain signal transmission in a pipeline such as a dust transport pipe in which the installation and management cost is reduced. CONSTITUTION:A transmitter-receiver 10a for sending/receiving a microwave is provided in a flange of a tip of a transport pipe 5 and a transmitter-receiver 10c is installed to a pre-stage of a separator 53 around a base of the transport pipe 5. Furthermore, a transmitter-receiver 10b is provided in an inspection part 40 located on the midway of the transport pipe 5. Then the communication is made in the pipe by allowing the transmitter to send a transmission signal to an inner space of the pipe 5 and allowing the receiver to receive the transmission signal. In this case, when the transmitter generates the transmission signal having a frequency in response to the inner diameter of the pipe 5, long range communication is made by using the pipe 5 as a waveguide. When the pipe 5 is a pipe transporting dust or the like, the signal is sent in the same pipe together with the transportation of an object such as dust.

摘要： PROBLEM TO BE SOLVED: To transport garbage/trash without wear on the inner surface of a transport pipe, and reduce production cost and without a special maintenance management by using a garbage/trash storing bag formed of material having a high strength and dynamic frictional coefficient. SOLUTION: A single-layered garbage/trash storing bag 10 is provided having the thickness of 30-120μm composed of material in which inorganic lubricant such as magnesium is added to polyethylene or polypropylene being a main material in order to improve the dynamic frictional coefficient to 0.5-0.10. Garbage/trash is stored in the bag 10 and transported in a garbage/trash transport pipe. Wear on the inner surface of the pipe is reduced with the low dynamic frictional coefficient of the bag 10. The production cost thereof is reduced with the single-layered structure having the high strength.

摘要： PURPOSE:To surely detect an obstacle at the inside over the whole length of a pipe by a method wherein a transmission signal is transmitted and received between one side and the other side in the inside space of the pipe and signals at its transmission and its reception are compared. CONSTITUTION:By using a signal from a transmission control device 7, a transmission device 10 which is installed at the base end part of a transport pipe 5 transmits an ultrasonic pulse signal to the inside space of the transport pipe 5. The pulse signal which has been transmitted inside the transport pipe 5 is received by a reception device 12 which is installed at the tip part. In addition, the device 7 outputs, to a detection device 3, the same signal as the signal which has been output to the device 10, and a reception control device 9 outputs, to the device 3, the signal which has been input from the device 12. At this time, the device 3 compares a transmitted signal with a received signal. When the pulse power value of the received signal is close to the pulse power value of the transmitted signal, it is judged that no obstacle exists inside the transport pipe 5. When the pulse power value of the received signal is remarkably low, it is supposed that the pulse signal has been attenuated by an obstacle, it is judged that the obstacle exists inside the transport pipe 5, and an alarm is given 60.

摘要： PROBLEM TO BE SOLVED: To transport garbage through a transport pipe without frictonizing its interior without increasing cost or necessitating special maintenance control. SOLUTION: After storing garbage in a high strength storage bag 20 and throwing the bag 20 into a garbage input port 1, an air flow lowered to 10 to 20m/s from a heretofore 20 to 30m/s by an air blower 8 is generated inside a garbage transport pipe 3 connecting the garbage input port 2 with a garbage collecting center 6 and internal friction of the garbage transport pipe 3 is designed to be prevented by transporting the storage bag 20 thrown in the input port 1 to the garbage collecting center 6 by carrying it on the air flow generated in the garbage transport pipe 3.

摘要： PROBLEM TO BE SOLVED: To reduce construction cost and efficiently perform transportation. SOLUTION: In a transportation line 1 between stations, a capsule 5 is transported by air flow generated by a blower 2, and in a movement line such as a launching line 13 or a braking line 12 in the station, fixed thrust or braking force is given to the capsule 5 by a synchronous type linear motor drive system having the positional sensor of the capsule 5, and hence the capsule 5 is transported.

摘要： PURPOSE:To transmit the radio wave even when the transportation of objects in a pneumatic transportation passage is stopped by providing an opening part in a valve plate so as to ventilate the air at the opened position, and providing an air shut-off part made of synthetic resin to shut off the ventilation of the air at the closed position. CONSTITUTION:A cylindrical body 1 is inserted in a pneumatic transportation passage, and mounted therein by aligning a passage 3 of the cylindrical body 1 to the pneumatic transportation passage. When an opening part 24 of a valve plate 23 is aligned to the passage 3 of the cylindrical body 1, an object to be transported by the pneumatic transportation passage can pass through the opening part 24 of the valve plate 23, and the radio wave can also pass. When an air shut-off part 25 of the valve plate 23 is aligned to the passage 3 of the cylindrical body 1, the object to be transported by the pneumatic transportation passage is shut off by an air shut-off part 25, but the radio wave can pass through and is transmitted through the shut-off part 25 because the air shut-off part 25 is made of synthetic resin. Thus, even when the transportation of the objects in the pneumatic transportation passage is stopped, the radio wave can be transmitted using the pneumatic transportation passage.

摘要： PURPOSE:To make use in an isolated island or during moving possible and to make the control of reaction air supply amount in response to the load change of a cell possible by preheating the air to be supplied to a cathode to high temperature when system operation is started. CONSTITUTION:When system operation is started, raw fuel and air for combustion are supplied to an exhaust heat recovery boiler 9, and they are burned there, and water from a pipeline 13 is converted into steam. The steam is supplied to a steam turbine 10 through a pipeline 14 to turn it. Reaction air is supplied to a preheater 12 with an air compressor 11, and the air is heated to high temperature by heat exchange with exhaust gas from the exhaust heat recovery boiler 9. The high temperature preheated air is supplied to a cathode of a fuel cell 1 to raise its temperature. When the cell 1 is heated to around 1000 deg.C, fuel is supplied to an anode, and power generation is started. When power load 17 is varied, revolutions per minute of the turbine 10 is controlled with a signal from a power load detecting system 18.
