A manifold for housing high-pressure oil on a camless engine includes an extruded aluminum body having first and second ends. The coating films are peeled from the base resin material of the coarsely crushed products 50 by loading either the coarsely crushed products 50 or the coarsely crushed products 50 and an abrasive in the cylinder 11 from the loading mouth 12 and by conveying the loaded products in the cylinder 11 while rubbing the same by the rotation of the rotary member 20. The high shear device may allow for lower reaction temperatures and pressures and may also reduce reaction time. This assures that only nodes on-the particular path will receive the special key or possibly some other information related thereto. The tops of the first and the second support legs are inserted into the holes of the cover and connected to the bottom of the falling part to prop the falling part open and air can flow through the cover.
