  • Patent number: 11117306
    Abstract: A screw machine includes an inductive heating device for processing of material to be processed. The inductive heating device is used to heat the material in a heating zone. In the heating zone, at least one housing portion is made of an electromagnetically transparent material at least partly, the material being non-magnetic and electrically non-conductive, whereas at least one treatment element shaft is made of an electrically conductive material at least partly. The inductive heating device includes at least one coil formed integrally with a component of the at least one housing portion, in particular in such a way as to form a hybrid component. During the processing of the material, the inductive heating device generates an alternating magnetic field that produces eddy current losses in the at least one treatment element shaft, the eddy current losses leading to a temperature increase of the at least one treatment element shaft.

  • Patent number: 8863722
    Abstract: A machined shape of a bore is based on the deformation amount of a data-acquisition bore after fastening of cylinder head. A cross section of an approximate shape is set to be an approximately-true circle shape, and a diameter of the approximately-true circle shape is changed along a central axial direction in accordance with the deformation amount of the data-acquisition bore, to determine the approximate shape. The approximate shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis. Since the machined shape of the bore is the shape obtained by reversing a phase of a recess and a projection of the approximate shape about a predetermined cylindrical shape, the machined shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis.

    Abstract: A machined shape of a bore is based on the deformation amount of a data-acquisition bore after fastening of cylinder head. A cross section of an approximate shape is set to be an approximately-true circle shape, and a diameter of the approximately-true circle shape is changed along a central axial direction in accordance with the deformation amount of the data-acquisition bore, to determine the approximate shape. The approximate shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis. Since the machined shape of the bore is the shape obtained by reversing a phase of a recess and a projection of the approximate shape about a predetermined cylindrical shape, the machined shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis.

  • Publication number: 20130055970
    Abstract: It has been difficult to manufacturing a cylinder head having an EGR gas cooling structure which has high cooling performance and can be easily configured. A cylinder head having an EGR gas cooling structure is configured in such a manner that a gas passage which guides to the air intake port side a part of the exhaust gas discharged from the exhaust port is disposed within the cylinder head water jacket to cool the exhaust gas flowing through the gas passage. The gas passage comprises a cooling section which makes contact with the coolant within the cylinder head water jacket, and also comprises a hollow pipe which has high-strength sections located at side portions of the cooling section and having higher strength than the cooling section. The high-strength sections of the gas passage are molded within and surrounded by the cylinder head.

  • Patent number: 8302305
    Abstract: There is provided a method for manufacturing a cast iron member in which the production of gas defects such as blowholes or pinholes in a clad layer formed on the surface of a cast iron material can be reduced, and the generation of bead cracks in the clad layer can be restrained. In the method for manufacturing a cast iron member, including a step of forming the clad layer by melting a material for cladding by means of irradiation of a laser emitted from a laser irradiation device and by depositing the melted material on the surface of a part of the cast iron material, the step of forming the clad layer is performed by using a material the main ingredient of which is a copper element as the material for cladding so that when the clad layer is formed, a hardened layer having a thickness of 0.01 to 2.0 mm is formed on the surface of the cast iron material.
