摘要： PROBLEM TO BE SOLVED: To provide a cylinder head cleaning method capable of enhancing a removal ratio of a foreign matter. SOLUTION: The cylinder head cleaning method cleans the cylinder head 1 formed with a water jacket 15 including a narrow space part Z for narrowing a flow passage and a large space part Y for enlarging the flow passage than the narrow space part Z inside and provided with a plurality of hole parts 12A-12R, 13, 14, 16A-16C communicated with the water jacket 15. In this case, cleaning nozzles 28A, 28C are inserted from the selected hole parts 16A, 16C out of the plurality of hole parts 12A-12R, 13, 14, 16A-16C into the water jacket 15, and a cleaning liquid is jetted from the cleaning nozzles 28A, 28C toward the narrow space part Z. The cleaning liquid flowing from the narrow space part Z to the large space part Y is discharged from the hole part 16B communicated with the large space part Y to the outside of the cylinder head 1.

摘要： PROBLEM TO BE SOLVED: To provide a leakage testing apparatus which can simplify its structure and reduce a manufacturing cost and a maintenance cost. SOLUTION: The first movable platform 16 is movably provided opposite to one side face of an object to be tested and provided with masking units 12-15 corresponding to openings of perforations on the side face of the object to be tested. Since the first movable platform 16 advances, the openings of the perforations on the side face of the object W to be tested are closed in an airtight state by the corresponding masking units 12-15. The structure of the leakage testing apparatus 4 is highly simplified and the manufacturing cost and the maintenance cost can be drastically reduced.

摘要： PURPOSE:To provide automatic assembly with one process even for an assembly requiring many assembling components. CONSTITUTION:A positioning device 3 is provided on the upper part of a rack 1 in such a manner as to be movable in three dimensions. X, Y, and Z axis. A main assembling position S0 and a plurality of sub-assembling positions S2 are established in the moving range of the positioning device 3 to allow the sub-assembling components to be supplied to each assembling position by means of component supplying devices 130, 131. A plurality of the sub-assembling components supplied from the component supplying devices are lifted by means of a component lifting device 132 located at each sub-assembling position to complete a sub-assembly. The sub-assembly is held by means of a component holding device 20 held by the positioning device 3 to deliver to the main assembling position. The sub-assembly is assembled on a main assembling component mounted on a component receiver 62 by the actuation of a press-in system.
