Title: Arc welding robot
Inventor: IDE EIZOU
IPC: B25J9/02
Filed: 1984-03-09
Abstract: PURPOSE:To obtain a joint free from welding defect by calculating a sum of length of arc protrusion and arc length and controlling the width of oscillation automatically based on the pattern of variation. CONSTITUTION:The average value and the effective value of welding current are obtained from a current detector 23 and amplifiers 29, 30. A voltage between a chip 12 and an object to be welded 16 is determined from a detected value of voltage 24, and a wire feeding speed v is obtained by a rotation detector 25. The sum of the length of wire protrusion and arc length is calculated from these values by computer 38. The computer 38 performs arithmetic so as to conform the average value for one cycle of the value of the sum with a set value based on the pattern of variation of the sum of the length of protrusion and arc length. Further, it performs arithmetic for controlling weld line copying and arithmetic for making the torch height constant, and controls each shaft of a robot. Thus, a sound weld joint free from defect is obtained.

Title: Boiling water reactor
Inventor: CHAGI MASAO
IPC: G21C15/02
Filed: 1994-03-17
Abstract: PURPOSE:To distribute the flow rate to a reactor core fuel assembly adequately, and to realize a high burnup of the fuel, by extending a coolant guide pipe in different sizes, between the lower end of a fuel holding metal fitting, and the upper end of a control rod driving mechanism housing. CONSTITUTION:A control rod guide pipe 9 connected to a control rod driving mechanism housing 8 loads a reactor fuel assembly 3 through a fuel holding metal fitting 12. A coolant guide pipe 28a to an assembly 3a forms its coolant entrance near the metal fitting 12, and its inner diameter is made smaller. As a result, the flowing-in coolant is mixed, and little influence is given to the dynamic pressure of a circulation pump, and the flow resistance in the pipe can be increased. A guide pipe 28b to an assembly 3b has its entrance between the housing 8 and the entrance of the guide pipe 28a, and it is made in a long size and a large diameter compared with the guide pipe 8a. A guide pipe 28c to an assembly 3c which has a further longer size and larger inner diameter has its entrance near the housing 8. As a result, the flow rate distribution to the coolants 3a, 3b, and 3c can be made adequately by the flow resistance of the guide pipe 28a, and the different inner diameter sizes and the heights of the entrances of the coolant guide pipes.

Title: Suction and exhausting device for air in water pipe line
Inventor: AKETO YASUO
IPC: F16K24/00
Filed: 1980-04-09
Abstract: PURPOSE: To prevent the sudden closing of an exhaust port, by a metod wherein, in a subject device for exhausting air in a pipe at a time when water flows to a newly installed line, a cylindrical valve is lifted for the first time after finishing the exhaustion of the air in the pipe by the buoyancy of intruded water irrespective of an exhausted speed.  
     CONSTITUTION: With air in a pipe compressed by the passage of water through a line, a check valve 19 is pressed to close a valve port 17, and air is exhausted through a flow port 13, a gap 14', a hole 16, and an intake exhaust port 29. Then, when water intrudes into a condition to permeate into a longitudinal channel 14''' and a guide cylinder through the flow paths 13, 14', and 16, and to exhaust through the intake exhaust port 29, a cylindrical valve 23 is floated by the buoyency, and a valve seat 24 closes the suction exhuast port 29. Air in the cylindrical valve 23 is then exhuauted, and a float valve 28 closes the hole 27 by the rise of the water level, meanwhile, the check valve 19 falls by its own weight. This permits the prevention of a sudden closing of the exhaust port during the passage of water through the line for the exhaustion of air.

Title: Buffer tank for silicon single crystal pulling machine
Inventor: OISHI TOSHIO
IPC: C30B29/06
Filed: 1986-03-06
Abstract: PURPOSE:To surely remove silicon oxide without causing clogging by colliding a gas contg. silicon oxide with plural partitions alternately arranged to change the flow direction. CONSTITUTION:The gas in a pulling machine body 1 enters the tank body from a pipe 13, collides with the inside partition 21, changes its flow direction, and flows toward the inner periphery of the tank body along the inside partition 21. The flow direction is then largely changed by the inner periphery of the tank body, and the gas flows to the center between the inside partition 21 and the outside partition 19. The flow direction is changed at the central part, and the gas passes through the hole 19A of the outside partition 19 and collides with the next inside partition 21. The process is repeated. When the flow direction is changed, the flow velocity is locally changed, and a turbulent flow is formed. Under such conditions, the gas is brought into contact with both partitions 19 and 21 and the tank body 11. The silicon oxide is removed from the gas coming out from the buffer tank 4.

CONSTITUTION:A stopper member 33 is bar-shaped and in two spots, projections 34 and 34' are formed at the same height. At the tips of the projections, buffer members 35 are provided. Further, holes 36 and 36' for fitting are bored at the both ends of the stopper member 33 and fitted to the opening surface at a recessed part 29 of a housing 28 by screws 37. In such a case, the projections 34 and 34' of the stopper member 33 and the buffer member 35 are installed at a position, where projections 27 and 27 collide, at the stop position of a carriage assembly 20. Therefore, since the structure is made simple and compact only by installing the buffer member at the stopper member, a wide space is not required and the accuracy of the stopper can be easily presented. Thus, the carriage stopper structure of a magnetic disk device can be obtained with high accuracy while decreasing the number of parts and reducing the space for installation with simple structure.
