Title: Cleaning method for centrifugal thin-film evaporator
Inventor: MATSUMURA SATORU
IPC: G21F9/28
Filed: 1986-07-16
Abstract: PURPOSE:To prevent powder from running off in a large quantity by introducing a mechanical powder removal process between a drying process and a cleaning process for removing powder separated inside an evaporator in the process of drying radioactive waste liquor. CONSTITUTION:After being stored for a while in a feeding tank 16, raw waste liquor is introduced from an inlet nozzle 11 to an evaporator 1, heated up by a heating medium introduced from a heating medium piping 19 and turned into powder to be stored in a powder hopper 28. As the process goes on, a large quantity of powder adheres to the inner surface of a heat transfer vessel 2 and a radioactive sensor 24 is actuated to stop feeding of the raw waste liquor. A drive shaft 8 stops to settle powder adhered, which are stored in the powder hopper 28. Then, the drive shaft 8 is started and cleaning liquid is fed from a nozzle 15 for cleaning, after which the drive shaft 8 is instantaneously started and stopped. By utilizing inertia force of the action, a rotor blade 9 is collided with the drive shaft 8 to cause powder to fall off to be drained out of a cleaning solution drain 30.

Title: Differential device
Inventor: YAMAZAKI SHINJI
IPC: F16H48/295
Filed: 1995-06-30
Abstract: PURPOSE: To provide differential limitting force immediately when differential rotation is generated by forming a bent part directed upward in the gravitational direction to branch oil in an oil channel to connect an oil reservoir and an oil chamber of a housing to each other. CONSTITUTION: An oil pipe 103 (oil channel) having a bent part 101 directed upward in the gravitational direction is connected to the top part in the gravitational direction of an oil pocket 97 through a coupler 105. Oil in an oil reservoir 5 is sucked in a gear pump 65 through the oil pump 103 and an oil chamber 99, and it is supplied to a pressure chamber 75 of a hydraulic actuator 63. As oil is branched at the bent part 101 even while a vehicle travels straight when the gear pump 65 stops, oil in a rising part 117 on the side of the oil reservoir 5 returns to the oil reservoir 5, but oil in the oil chamber 99 never drops in the oil reservoir 5. Consequently, when differential rotation is generated in a differential mechanism 57 and the gear pump 65 is actuated, oil in the oil chamber 99 is immediately delivered to the hydraulic actuator 63.

Title: Flat coreless motor
Inventor: NAKAJIMA KOICHI
IPC: H02K23/58
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a flat coreless motor which is able to increase the oscillating amount, without the motor being thickened unnecessarily, and rotate the rotor itself stably. SOLUTION: This coreless motor is formed by disposing a weight 5, which has roughly identical thickness to a rotor 4 and is formed out of compound engineering plastics whose density is 6-18 or metal working, at the outer- periphery of the rotor 4. As a result of the configuration, in the case of the eccentric rotor, the movement amount of the center of gravity of the rotor can be increased without the motor being thickened unnecessarily or the size of the magnet being reduced unnecessarily, thus it is possible to reduce the diameter of the motor easily. In the case of the disc-shaped rotor, inertia can be increased, thus it is possible to restrain the rotational oscillation or rotational unevenness of the rotor, thereby rotating the rotor stably.

Title: Screed heating device
Inventor: SAKAKIBARA AKIRA
IPC: E01C19/48
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent a blower from being burned by backfire by controlling a valve with a controller to immediately close the valve for stopping fuel supply instead of stopping the fuel supply by the conventional manual operation in order to immediately eliminate misfire or backfire in a combustor when air blowing from the blower is stopped or air blow amount is insufficient due to unforeseen accidents such as snapping of electric wiring. SOLUTION: A rotation detector is installed on a blower 11. The rotation of a fan 11b is detected by the detector so that a controller 12 can recognize the state of air blowing from the blower 11 to a combustor 14. The controller 12 which recognizes the state of air blowing controls a solenoid valve 13 according to the state of air blowing to control the supply of gas G to the combustor 14. By this constitution, even when the fan 11b is stopped, or its rotating speed is reduced, the controller 12 controls the solenoid valve 13 to control the supply of gas G to the combustor 14. Thus, a flame in the combustor 14 is not back- fired, and the blower 11 is prevented from being burned out.

Title: Take-out device for long material while traveling
Inventor: TANAKA KAZUHIRO
IPC: B21B39/00
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To take out a traveling long material independently of the size of the long material and reduce the cost of the device by rotating a rotor where variable-width long material receiving gap portions are formed at designated intervals, and taking a traveling material in the gap portion and releasing the same in the lateral direction. SOLUTION: When a traveling material receiving gap 14 of a rotor 13 driven by a servo motor reaches the top face 12a of a traveling table 12, a traveling material 11a traveling a contained angle made between the top face 12a of a traveling table 12 and the peripheral surface 13a of a rotor 13 is taken in the gap portion 14 by its gravity while it passes there. Subsequently, with the rotation of the rotor 13, the traveling material 11a is carried as shown by 11b, 11c, 11d to be remote from the traveling table 12 and when the material reaches the opposite side 11d to the traveling table 12, it is released to a cooling floor. In the case where the diameter of the traveling material 11a is small, the space of the gap portion 14 is narrowed by an adjusting member 16. Thus, even with a small-capacity motor, the speed of passing the gap portion 14 can be controlled to a desired speed.
