Abstract: On a second thermo-module there are disposed a prism, an optical filter, and a sub-mount, via a base respectively. On the front side of the sub-mount, there are disposed a first photodetector and a second photodetector. The optical filter is structured with a crystal member that satisfies a condition that ?+(1/n0)×(?n/?T) becomes not more than 3.5, where ? is a coefficient of linear expansion, n0 is a refractive index at a normal temperature, and ?n is a change of a refractive index corresponding to a temperature variation ?T.

The optical filter is structured with a crystal member that satisfies a condition that &agr;+(1/n0)×(&Dgr;n/&Dgr;T) becomes not more than 3.5, where &agr; is a coefficient of linear expansion, n0 is a refractive index at a normal temperature, and &Dgr;n is a change of a refractive index corresponding to a temperature variation &Dgr;T.

Abstract: An etalon filter of the invention is an etalon filter where the light transmission property depending on temperature is reduced, which is preferable as an optical device. An etalon filter (11) has a filter main body (1) where reflecting films are disposed on a light input side surface and a light output side surface of a light transmission medium. The etalon filter (11) is formed by disposing different linear expansion coefficient members (2) having a coefficient of linear expansion different from that of the light transmission medium in areas on both sides of the filter main body (1) except optical path length areas (4).

Abstract: A pair of front and rear arm brackets for supporting swing arms extends between and is integrally joined to a pair of laterally spaced lower frames, and a steering bracket for supporting a steering shaft is disposed between the front and rear arm brackets and between the lower frames, and is integrally joined to the front and rear arm brackets and the lower frames. The front and rear arm brackets and the steering bracket are assembled and welded together into a lower component before being joined to the lower frames. The lower component is positioned on a positioning table, and then positioned with respect to the lower frames by a setting jig for high positional accuracy. The setting jig has lateral cylinder units for laterally gripping the arm brackets and front and rear cylinder units having positioning pins for being inserted into attachment holes defined in the arm brackets to position the arm brackets.

Abstract: A welding line system has a transfer robot dispose closely to and between a workpiece loading line for loading preliminarily welded four-wheeled buggy frames and a workpiece unloading line for unloading fully welded four-wheeled buggy frames. The welding line system also has a main welding station including a plurality of welding sections disposed around the transfer robot and having respective workpiece holders. The workpiece holders are arranged such that the preliminarily welded frames supported thereby have respective longitudinal axes whose hypothetical extensions cross each other in the vicinity of the transfer robot. The transfer robot transfers preliminarily welded frames successively delivered along the workpiece loading line successively to the workpiece holders, and receives fully welded frames successively from the workpiece holders and discharges them to the workpiece unloading line.
