Abstract: The present invention provides a method of making a semiconductor laser module, the method having a first step of regulating the attitude of a package such that the lens fixation end face of the package will have a predetermined angle relative to a predetermined reference axis, a second step of placing a condensing lens on the lens fixation end face of the package, a third step of detecting the inclination of the laser beam passed through the condensing lens relative to the reference axis, a fourth step of fixing the condensing lens to the lens fixation end face at a position wherein the inclination of the laser beam relative to the reference axis falls within a predetermined range of angle and moving the condensing lens to the position if the inclination is out of the predetermined range of angle, thereby fixing the condensing lens to the lens fixation end face at that position, and a fifth step of aligning and fixing the optical fiber such that the desired amount of laser beam passed through the fixed conde

Abstract: An improved reactor is disclosed wherein a high temperature product gas discharged from a catalyst bed within the reactor is cooled in a central heat exchanger installed within the reactor by heat exchange with a low temperature feed gas comprising gaseous raw materials for the reaction, and the product gas is thereafter flowed along the inner surface of an outer pressure vessel in order to maintain the outer pressure vessel at a low temperature. Inlet and outlet pipes for a coolant which coolant is circulated through a coolant passage structure which penetrates the catalyst bed in order to absorb the heat of reaction, both penetrate the top cover of the outer pressure vessel so that the coolant passage structure can be readily removed for maintenance and inspection, and the overall design of the reactor is simplified.
