Abstract: A laser processing method includes a first step of irradiating a surface of a composite material with a laser to form a hole processing groove on the composite material by scanning first paths from an outside corresponding to an inner peripheral surface side of a through hole to be formed to an inside corresponding to a center side of the through hole to be formed, the first paths extending across a width direction of the hole processing groove; and a second step of irradiating and penetrating through the hole processing groove with the laser to form the through hole by scanning second paths from the outside to the inside after the first step, the second paths extending across the width direction of the hole processing groove. The laser used at the first step has a smaller heat input amount per unit time than the laser used at the second step.

Abstract: A process and apparatus are provided for generating at least two types of steam having different purities in steam reforming processes in which at least two steam reforming units (steam reformers) (are operated in parallel. The first steam stream having a higher purity than that of the second steam stream. The steam reformers operated in parallel are combined to form groups of at least two steam reformers (groups) within which the high purity steam is generated in one of the steam reformers by vaporization of degassed and demineralized water and low purity steam is generated in at least one of the other steam reformers by vaporization of degassed impurity-containing water (dirty water). The dirty water is formed at least in part from the condensate (process condensate) produced within a group, and is predominantly made up of water.
