Title: Prevention device for approach of bed material to bottom surface and side surface of air diffusing pipe
Inventor: OKAMOTO HIROHISA
IPC: F23C10/20
Filed: 1993-02-10
Abstract: PURPOSE:To prevent the generation of air leakage or erosion by supporting a main air diffusing pipe body of a unitary form in a sliding manner, attaching bellows expanding in accordance with the thermal deformation of the main air diffusing pipe body to an air blowing duct and controlling the displacement of the main air diffusing pipe body by a controller. CONSTITUTION:A main air diffusing pipe body 6 of a unitary form is supported by a support member 3 and a support member provided in an air diffusing pipe support column inlet header 4 in a sliding manner. An air blowing duct 9 is provided with a bellows 14 expanding following the thermal deformation of the main air diffusing pipe body 6. A controller for limiting the amount of thermal deformation of the main air diffusing pipe body 6 to a prescribed value or lower is provided between the air diffusing pipe support column inlet header 4 and the outer side surface of the main air diffusing pipe body 6. A bed material approach preventing cover 34 filled with a heat insulator is provided between an adjacent main air diffusing pipe body 6 and the controller. Accordingly, a sealing characteristic is improved and the breakage of the bellows 14 can be prevented. Since a bed material does not enter the side surface and the bottom surface of the main air diffusing pipe body 6, the main air diffusing pipe body 6 can be restored to an original form when the thermal deformation is eliminated.

Title: System for decreasing attenuation of radio wave due to rainfall
Inventor: UMEHARA TADATOSHI
IPC: H04B1/04
Filed: 1986-02-05
Abstract: PURPOSE:To reduce the attenuation of a radio wave due to rainfall by dividing transmission power into two equally, radiating the power from two antennas to one reception point, deviating the direction of the radiation pattern of one antenna at rainfall and making the phases of the two antennas opposite to each other. CONSTITUTION:While the transmission power is divided equally into two, the in-phase and equal level of power is radiated from the two antennas T1, T2 to a remote reception point R for communication, if a rainfall region takes place on the way, the direction of the antenna T2 is changed a little, the radiation patterns are crossed together at the intermediate point P of the rain region between the antenna T1 and the point R so as to adjust in a way that the radiation fields from both antennas at the said point are of equal magnitude and in opposite phase. Since the electric field is made nearly equal in the magnitude and opposite in phase in the entire rainfall region and the combined electric field is decreased in this way, the attenuation due to the rainfall region is decreased.

Abstract: PURPOSE: To maintain a high cleaning ability of cleaning water to be supplied in circulation to an eliminator, through selective blowing of dirty liquid after cleaning by using a partition plate to divide a cleaning water tank for cleaning mist eliminator.  
     CONSTITUTION: A cleaning water tank 7 is divided by a partition plate 13, with one side being provided with an after-cleaning clean water inlet line 12 and a cleaning water blow line 9, with the other side being installed with a supplying water line 6 and a cleaning water circulating line 5. The liquid in both sides are connected through connecting section 13A below the partition plate 13, so that the same level is maintained in both side. The liquid after cleaning the eliminator and containing a lot of solid is returned to the tank 7 from the inlet line 12. The liquid, however, because of the partition 13, is not diluted with a clean supplying water, and is selectively sent to the next cooling process 10 via the blow line 9. This maintains the supplying water side of the tank to be clean, so that clean water can be supplied through the circulation line 5 to the eliminator.

IPC: B21D11/14
Filed: 1987-02-02
Abstract: PURPOSE:To deform a blank by twisting, to change the inclination angle of a movable die if necessary and to continuously change a twisting pitch by passing through the blank in the state of varying the inclination of both dies of a set of fixed and stationary dies. CONSTITUTION:A stationary die 3B and mobile die 3A are unable to move a blank A in neither thickness direction nor width direction but catch movably in the longitudinal direction only. The blank A receives a plastic deformation while passing through both dies 3A, 3B in this catching state to change the twisting deformation amt. in various sizes according to the size of the relative inclination angle (a) of both dies 3A, 3B. When, therefore, the inclination angle (a) is changed by operating the mobile die 3A, a twisting bar T is formed with changing the twisting pitch continuously. The blank A is rotated in the twisting deformation direction when the blank A is passed through both dies 3A, 3B. In order to pursue, this a chuck 13 is supported freely rotatably.
