摘要： An apparatus for replacing the tool sets without requiring any fixing or removal of the fluid pressure pipes such as hydraulic hoses or the like when the tool sets are fixed to or removed from the main body of the power molding press. Swing arms 6 having arm lengths set therein are oscillatably and rotatably fitted to the arm shafts 5 vertically installed at proper side locations of the main body 1 of the press in such a way as the rotating radius of the arm shafts may overlap the mounting position of the main body 1 of the press. The extreme ends of the swing arms 6 are provided with supporting boxes 7 on which the tool sets 3 are mounted. Rotation of the swing arms 6 enables the tool sets 3 to be moved toward or away from the centeral part of the main body 1 of the press and then the tool sets 3 to be fixed to or removed from the main body 1 of the press. The fluid pressure pipe passages for driving the tool sets 3 are connected in advance to the operating fluid pressure source at the main body 1 of the press near the aforesaid arm shafts 5 through the joint means following the rotation of the aforesaid swing arms 6.

摘要： The invention provides a press for powder metallurgy in which a die set installed between an upper ram and a lower ram of a main body of the press can be easily fixed or removed and the accuracy of the molded product is improved. An upper part of the lower ram to which a yoke plate of the die set is installed or is provided with a gap adjusting screw displaceable with thread engagement in vertical direction. A hydraulic actuator or other rotary driving device is fixed to a lower part of the lower ram. A driving shaft of the rotary driving device is connected to the gap adjusting screw by a connecting shaft which passes through an axial center of the lower ram. When the die set is installed in the main body of the press, the gap adjusting screw is retracted within the lower ram so as to assure a sufficient gap between the yoke plate and the lower ram. When insertion of the die set is completed, the gap adjusting screw is advanced forwardly to abut against the yoke plate and thus they can be assembled with a gap having no clearance approximating to zero.

摘要： A bearing with an oil film thickness measuring device in which sensor portions at distal ends of four common optical fibers are connected to sensor mounting portions formed at four positions in an axial direction of a bearing body. A lubricating oil containing a fluorescent agent is supplied to a sliding surface of the bearing body. A laser beam generated from a laser beam generator is branched into four beams, which are applied to an oil film on a sliding surface through each of sensor portions. Fluorescence generated by the fluorescent agent in the oil film, passing through a return-route optical fiber, is introduced into a photomultiplier tube, and is detected. Since the fluorescence intensity detected by the photomultiplier tube is proportional to the thickness of oil film, the absolute value of oil film thickness can be measured. In this case, the oil film thickness can be measured at four positions.

摘要： The invention provides a heat recovery method for use in sulfuric acid production plants by which the heat generated in the step of drying SO2 gas or the step of drying air, and the step of absorbing sulfur trioxide in the plant is effectively utilized for heating the water to be supplied to a boiler although the heat is conventionally discarded because of the difficulties encountered in using the heat effectively. The boiler water to be supplied is heated by utilizing the heat generated by drying and/or absorption in a drying tower of the plant for drying sulfur burning air or the sulfur dioxide and/or in an absorption tower of the plant for causing circulating concentrated sulfuric acid to absorb sulfur trioxide produced by the conversion of the sulfur dioxide.
