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.

摘要:
A heat-sensitive recording material in which a heat-sensitive color-developing layer comprising, as the main components, a usually colorless or light-colored color former and a developer capable of developing the color former upon heating on a support, characterized by comprising, as the developer, crystals of 3,3'-diallyl-4,4'-dihydroxy-diphenyl sulfone which have DSC (Te) of at least 149.degree. C. and which are of a crystal form characterized by an X-ray diffraction pattern having peaks at least at diffraction angles (2.theta.) [.degree.] of 7.2 and 22.0, obtained by an X-ray powder diffractometry using Cu--K.alpha. rays. This heat-sensitive recording material is high in sensitivity, little in Discoloration of the ground in heat and moisture and excellent in image durability.
