Abstract: A tool holder for a machine includes a frame including at least one hook-shaped cut-out for receiving a first bracket pin of a tool and a least one partial cut-out for receiving a second bracket pin of the tool; an actuator connected with one end to the frame, the actuator including an actuator housing arranged movable compared to the frame upon activation of said actuator, the actuator housing further including lock fingers designed to change the shape of the at least one partial cut-out so that second bracket pin of the tool can be locked in the tool holder and the at least one partial cut out, respectively; and an actuator positioning system including a pattern, a sweep sensor, a processor and a computer readable memory.

Abstract: A method for manufacturing a gas concentration calculation device including a housing made of a synthetic resin and configured to include a cylindrical portion including first and second openings, respectively, at axial both ends thereof, and first and second mirrors, respectively, arranged facing each other at the first and second openings to form an optical path of infrared light inside the cylindrical portion. The method includes a step of preparing a precursor including respective sticking-out portions made of a synthetic resin sticking more outward than respective installation positions of first and second mirrors in a cylindrical portion and a step of bonding the first and second mirrors to the respective installation positions by arranging the first and second mirrors, respectively, at the respective installation positions of the precursor and then bending the sticking-out portions while melting with heat to cause them to adhere to the first and second mirrors.
