In a cylinder block manufacturing method, first and second dies and a liner support are provided to form a liner overcast configuration. The collecting housing is designed as a section of the exhaust gas line for the internal combustion engine. The p-type silicon single crystal substrate is moved along the substrate feeding surface towards the rotating groove-carving blade while keeping a close contact of the first main surface thereof with the substrate feeding surface. The information presenter wirelessly provides data to be transferred to an external data reception module. The slider design of the present invention provides a stiffer air bearing, in that the slider resists changes due to gram loading to achieve a narrow distribution in flying height variations as well as roll and pitch variations. A tapered optical element is coupled to an optical fiber, when both the tapered optical element and the optical fiber are mechanically secured by crimping the metal tube and the silicone insert in the proximity of the first and second sets of grabbers, as by using a standard crimper tool.
