摘要： PURPOSE: To conduct stable pneumatic transportation at a fixed volume of solid body containing coarse particles or block materials to a next high pressure process without using a mechanically operated means. CONSTITUTION: In a coarse particle separating type feeding unit, a cylindrical coarse particle separating pipe 27" is installed under an outlet of a feeder 27', and coarse particle separating gas (producer gas or inert gas) is horizontally fed from a side wall of the coarse particle separating pipe 27". When a gas flow velocity in the coarse particle separating pipe 27" is set not higher than a terminal velocity of a particle to be recovered, the particle of several mm or larger in diameter is dropped in the coarse particle separating pipe 27", while the particle having a velocity higher than the terminal velocity is conveyed by gas flow to flow into a raw material discharge pipe installed on a side wall of the feeder outlet, and pulverized coal, char or the like are fed to a high pressure furnace or the like. A differential pressure monitoring device is provided for monitoring a differential pressure between the feeder 27' and the coarse particle separating pipe 27", a differential pressure between the feeder 27' and the raw material discharge pipe, and a differential pressure between the coarse particle separating pipe 27" and the coarse particle recovering unit, and whether or not coarse particle recovering and fine particle discharging are stabilized is grasped based on a varying state of each differential pressure.

摘要： PURPOSE:To enable working efficiency to be improved by providing legs supporting a device at upper and lower legs so that they can be mounted and removed freely, by providing a suspension mechanism within the upper and lower legs, by supporting the device with a leg as a supporting member on free standing, and by supporting weight with the suspension mechanism by dividing the legs on suspension. CONSTITUTION:An upper leg 37 and a lower leg 38 are connected by a bolt 39 for free standing. Then, an upper mirror switching device and an upper mirror 1 are suspended together by a ceiling crane for suspension. At this time, the leg 37 is lifted together with a box 31 and is separated from the leg 38 by removing the bolt 39. At the same time, a pin 32 is lifted up and the upper surface hits against a stopper 36. Namely, weight of the upper mirror 1 is transmitted to a stiffener 22 through a suspension fitment 6, a pin 35, a lug 34, a suspension bar 33, a turnbuckle 24, a suspension bar 33, a stopper 36, a pin 32, and a box 31. Finally, a process for moving the upper mirror 1 and lowering it onto a tentatively-placed stand is performed in the reversed order of suspension, thus enabling working efficiency to be improved and exposure of a worker to be reduced.

摘要： PURPOSE:To permit a valve to easily maintain its opening and closing function by detachably connecting a valve seat to a valve unit by a guide, provided in the valve unit, and a roller mounted to an expansion joint. CONSTITUTION:A ball valve unit 1, positioned in the center, rotates 90 deg. when a flow path is switched. A valve seat 2 is mounted to the point end of an expansion joint 3 having a fluid chamber able to expand and contract. When the ball valve unit 1 is rotated 90 deg., also a guide 7, integrally formed with a valve shaft 12 and the ball valve unit 1, simultaneously rotates. The guide 7 provides a groove 19 with an almost 90 deg. space, and by this groove 19, a roller 6, integrally formed with a set flange 13 and a closed flange 14, comes into contact with the guide 7, as the result, the flanges 13, 14 move along a rod 4, preventing the valve seat 2 and the ball valve unit 1 from sliding.

摘要： PURPOSE:To reduce the weight of an internal cylinder part, to improve weighing accuracy, and to preclude contamination by fitting a hammering device on the outside flank of an external cylinder and providing a secondary hammer which cooperates with the piston of the hammering device so that it penetrates the external cylinder. CONSTITUTION:The radioactive powder 20 put in the internal cylinder 3 of double cylinder structure is weighed by a weighing machine 4 and a discharge door 7 in the bottom surface of the internal cylinder 3 is opened after it is confirmed that a specific amount of powder is put in the internal cylinder 3, thereby discharging the radioactive powder 20 through the internal cylinder 3 and the hopper of the external cylinder 2. At this time, the hammering device 5 strikes on the internal cylinder 3, which is vibrated to discharge the radioactive powder 20 from the internal cylinder 3 smoothly and securely. In this case, driving force 21 from the driving piping 6 of the hammering device 5 is sent to the hammering machine 5 fitted to the external cylinder 2 to push the piston 13 and move the secondary hammer 9, thereby striking on the internal cylinder 3.

摘要： PROBLEM TO BE SOLVED: To provide a method for exchanging information with security in an enterprise information system. SOLUTION: In a network system, where a client and a business server can exchange communication, a client authentication method using an irreversible function makes it possible to exchange the authentication information with security when the method is provided with a means that converts security information of the client, so that the information cannot be extracted by converting authentication information of the client by an irreversible function and a means that revises authentication information each time by using a value generated by the server and different each time, so as to prevent other person to pretend to be the client through interception. Or the client or a 3rd device generates different values each time and the authentication is generated on the basis of the values to exchange the authentication information with security.
