Title: Method for straightening welding strain of carriage frame
Inventor: MAEYAMA KOUICHI
IPC: B23K31/00
Filed: 1982-09-07
Abstract: PURPOSE:To straighten by heating the quantity of weld strain down to a press quantity and to improve the efficiency in the operation for straightening for a carriage frame, by assembling right and left side beams and a cross beam to an H shape, pressing the assembly with press ram devices provided with pressure gages disposed on both sides of the side beams and welding the assembly. CONSTITUTION:Side beams 2, 2 and a cross beam 3 are placed in an H shape on a positioner 8. The rams 17, 17 of the cylinders 15, 15 of a ram device are advanced to press the side faces of the axle spring seats 6 of the beams 2, 2 by pressing force Q so that the beams are held in the state of applying prescribed elastic strain toward the outside. The butt parts of the beams 2, 2 and the beam 3 are welded to assemble a carriage frame. The beams are pressed in this state in such a way that welding strain is generated in the beams 2, 2 and the seats 6 return the rams 17 into the cylinders 15. The value of Q+Q' is registered on pressure gages 18 if the pressing force is designated as Q'. When the carriage frame is heated with gas torches 7 to straighten from the weld zones, the value Q+Q' decreases gradually. The heating is stopped at the point of the time when the value decreases to the initial value Q. When the pressing force of the rams is released, the strain by the force Q restores the original strain and the weld strain is straightened.

Title: Overflow preventing device for water supply pump
Inventor: SHIDA TOUICHI
IPC: F04B49/00
Filed: 1979-12-05
Abstract: PURPOSE: To change the load characteristics of a water supply pump and make the best use of the water supply pump capacity, by controlling a flow rate control valve depending upon the speed of revolution of the water supply pump together with its suction flow rate, and returning a part of water supply flow to its source.  
     CONSTITUTION: Suppose that TDRFP-A is tripped, then B of a relay 22 closes and the suction flow rate of TDRFP-B moves to point R from illustrated point P. In this case, since QCB is set in illustrated point Q, an HPCP recycling valve 16 moves to Q from opening port R so that it can be corrected only for the deviation of points Q and R. Besides, the number of revolutions of TDRFP-B is increased by the actuation of a water supply control system. Following this, QCB changes also and HPCP recycling valve 16 is controlled so that a moving point is always positioned on curve D. Thus, the normal condition of TDRFP is maintained continuously so th at the maximum allowable capacity of water supply may be availably for an atmoic reactor.

IPC: G06K7/10
Filed: 1981-10-01
Abstract: PURPOSE:To rationalize the operation of an operator, by carrying out a display corresponding to the data item to be scanned, giving no change to the display unless the reading is not correct and performing a display corresponding to the item to be scanned next when the reading is correct respectively. CONSTITUTION:A hand scanner 1 is shifted right and left and along a price tag 4 to read the characters one by one. The characters are discriminated by a discriminating circuit, and a character arranging circuit rearranges the characters in the same way as the case when the scanner 1 is shifted from left to right although the scanner 1 is shifted from right to left. A collating circuit decides whether the discriminated characters are correct or not and whether plural lines are read in a correct sequence. When the characters are correct, the read-out data is set to a register. At the dame time, a display element 10 corresponding to the next item is turned on. In case a wrong data is read, no change is given to the glowing position of the element 10. As a result, an operator can know at his or her side whether the correct reading is carried out as well as the data item to be supplied next.
