Abstract: PURPOSE: To prevent blow-up of gas passing a downward pipe, by providing a check valve in a downward pipe in each rack stage of bubble-cap tower type vapor- liquid contact apparatus, and shielding the opening of the downward pipe when the apparatus oscillates.  
     CONSTITUTION: A plate 3 in scores of steps having plural through-holes having tray caps 4 and a weir 5 is disposed in a main body 1, and each stage is connected with downward pipe 2 to compose a bubble-cap type vapor-liquid contact apparatus, in which a check valve is provided in the downward pipe 2.

Title: Production of twisted product of aluminum or aluminum alloy extruded shape and formed product
Inventor: TSUGE MITSUO
IPC: B21D53/78
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a twisting method suitable for forming a fan blade etc. by imparting a twist angle in high precision while maintaining a cross sectional shape of an aluminum alloy extruded shapes. SOLUTION: For an extruded shape 11, a pair of fixed side rolls 20 and a pair of rotating side rolls 21 of an outer peripheral shape corresponding to the sectional shape of the shape in a respective side are arranged to both sides along its longitudinal direction, the extruded shape is passed between these rolls, while forming a relative twisting relationship between a pair of the fixed side rolls by rotating a pair of the rotating side rolls around the axis along the longitudinal direction, twisting deformation is imparted by continuously drawing. When the extruded shape has a hollow cross section, by arranging a core having a shape in internal contact with a hollow part inner face, cross section precision is improved. Further, by constructing each roll with plural roll bodies independently rotatable, resistance as well as a tension load are reduced.

Title: Combustion disc of burner
Inventor: KOBAYASHI SHIGEO
IPC: F23D11/06
Filed: 1983-05-12
Abstract: PURPOSE:To enable sharp adjustment of the fuel, by a method wherein a wire net, forming mesh with size smaller than the diameter of a nozzle, is firmly adhered and stretched to the surface of a combustion disc having nozzles through which gasified fuel is injected. CONSTITUTION:A wire net 4, forming mesh 3 with size smaller than the diameter of a nozzle 1, is firmly adhered and stretched to the surface of a combustion disc 2 having nozzles 1 through which gasified fuel is injected. This causes gasified fuel to be injected ahead through the nozzles 1, and when the gasified fuel is ignited, flames injected through a number of nozzles 1 are joined together at the entire front face of the combustion disc 2 to form a large flame, and a combustion operation takes place. The gasified fuel, injected through the combustion disc 2, collides with the wire net 4 making contact with the front of the nozzle 1 to exert the resistance thereon, and the injection force of the gasified fuel is decreased and diffused and a distance between the flames is decreased, whereby the occurrence of a lift phenomenon and a blow-out phenomenon at a low flow rate range of the fuel is decreased, and safety of the flame during a time between a low flow rate range and a high flow rate range can be maintained.

Abstract: PURPOSE:To enable adaptation to moving inspection patterns by detecting the attitude of a projection image on a diffusion screen with an attitude sensor to adjust the angle of inclination with respect to the surface of an object to be measured depending on the angle of crossing between optical axes of a laser generator and a line sensor for detection of defects and the optical axis itself. CONSTITUTION:In an adjusting mechanism 13, a drive motor 25 swings a laser generator 15 in the direction thetax through a ball screw 26 to adjust the angle delta of crossing between the optical axes L1 and L2 of the laser generator and a detector 16. Also in the adjusting mechanism 10, a drive motor 19 swings a mobile stay 12 in the direction of the arrow thetay through a flat gear 21 to adjust the angle epsilon of inclination with respect to a painting surface 30a defined by the optical axes L1 and L2. Then, even though a slit image on a screen 31 is displaced from the linear portion 31a with changes in the relative positional relationship between the generator 15, the device 16 and the surface 30a, the parallel movement and rotation of the slit image are detected with a line sensor for attitude detection in a camera 33 to control of the rotation of the drive motors 25 and 19 thereby adjusting the angle delta of crossing and the angle epsilon of inclination. Thus, the slit image displaced can be returned to the portion 31a.

Abstract: PURPOSE:To update a new table at each frame and to attain a DFA picture processing having a suitable contrast, by obtaining a peak value of an input amplitude of an enhancement circuit sequentially and performing the change in the convering characteristics based of this peak value. CONSTITUTION:The enhancement circuit 35 consists of a comparator 40, latch circuits 41,42, a table forming circuit 43, and a lookup RAM table memory 44. The lookup memory 44 has the converting characteristics predetermined, and the converting characteristics are changeable automatically. The new converting characteristics are formed with the table forming circuit 43 and stored in the lookup table memory 44 in place of the old converting characteristics. The comparator 40 compares the magnitude of the first picture data A from a frame memory 34 with that of the past maximum value B of the latch circuit 41. Further, e.g., the value A is latched to the latch circuit 41 as a new maximum value in place of the maximum value so far. The latch circuit 42 receives the maximum value of the proceding frame from the latch circuit 41 and latches it. The maximum value of the preceding frame latched in the latch circuit 42 is fetched in the table forming circuit 43 to form the new converting characteristics.

Abstract: PURPOSE: To separate a pen in an automatic manner from recording paper, in case the latter is broken, thereby to make it unnecessary to monitor a recorder at all times by providing pen separating means having a thermally deformable element.  
     CONSTITUTION: Under the condition in which a pen point 3a is effecting the normal record in recording paper 10, the pen point 3a and a recording paper carriage 9 are isolated by the paper 10. As a result, a thermally deformable element 5 receives no current. If the paper 10 is broken by any reason so that the pen point 3a comes into contact with the carriage 9, a low current flows through a resistor 8, the pen point 3a and the carriage 9 in this order and is amplified by a current amplifier circuit 11 until it flows into the element 5. As a result, this element is warped in the direction of reference letter Y by the heat generated so that the pen 3 is raised through a lever 6. As a result, the pen point 3a is separated from the recording paper 10.

Abstract: PURPOSE:To perform a smooth start without accelerative vibration by generating a sudden change of friction torque, when an elevator with reduction gear is started, serving as a compensation control signal at the time of starting correcting the speed reference from a speed controller. CONSTITUTION:A speed controller 10 controls a speed of an electric motor 1 in accordance with a deviation between a speed reference from a speed command generator 9 and a feedback signal from a speed detector 7.

When an elevator speed increases thereafter to a predetermined value, a start compensation separator circuit 41 is separated by an output of a speed level detecting circuit 40. Thus a smooth start without accelerative vibration can be performed.
