A surface emitting laser device is disclosed that is able to selectively add a sufficiently large loss to a high order transverse mode so as to efficiently suppress a high order transverse mode oscillation and to oscillate at high output in a single fundamental transverse mode. The surface emitting laser device includes a first resonance region that includes an active layer and spacer layers, two distributed Bragg reflectors that sandwich the resonance region, and a current confinement structure that defines a current injection region for the active layer. At least one of the distributed Bragg reflectors includes a second resonance region arranged in the current injection region excluding a predetermined region surrounding a center of the current injection region.

An electrical connector (100) includes an insulative housing (40) and a terminal module (10) retained in the insulative housing and configured with a selected terminal (11), a determined terminal (12) and a specific terminal (13) molded within a dielectric wafer (2). A coupling lead-frame (3) is disposed onto a surface of the dielectric wafer and has its main portion (3a) parallel and aligned with the specific terminal. The coupling lead-frame includes one pin leg (311) crossing over the determined terminal and having a physical and electrical engagement with the selected terminal so as to establish an electrical coupling between the selected terminal and the specific terminal.

The present invention provides a connector capable of being easily and reliably coupled to a printed circuit board. A connector (10) comprises two sets of a plurality of lead parts (31) and a plurality of lead parts (41) extending from one side surface (11) of a housing (1) to be opposite to each other. A printed circuit board (20) includes slot (21) abutting on the side surfaces (11) to (13) of the housing (1), and edge connectors (22A) and (22B) are formed on both surfaces of an edge abutting on the one side surface (11). The edge connectors (22A) and (22B) are inserted between the lead parts (31) and (41), and the lead parts (31) and (41) are soldered to the edge connectors (22A) and (22B), respectively. In a pair of first protrusions (14A) and (15B), a recess (140) for gripping the printed circuit board (20) is formed, and the recess (140) is aligned in the same row as the opposing gap between the lead parts (31) and (41), The second protrusions (15A) and (15B) each have a supporting surface abutting on one surface of the printed circuit board (20), and respectively protrude from the side surfaces (12) and (13) arranged opposite to each other.

The present invention relates to a piston valve assembly which is used in a continuous damping control damper using magneto-rheological fluid. The piston valve assembly is coupled with an end of the piston rod, and a stopper having a flat upper surface which is surface-contacted with an upper plate is disposed between a core assembly and the upper plate, thereby properly dispersing a force applied to the piston rod.According to the present invention, the reliability and stability in the coupling between the piston rod and the piston valve assembly can be increased, thereby stably controlling the damping force of the damper. Further, the slot is formed in the core of the piston valve assembly so as to reduce the damping force in the lower speed range, thereby considerably improving the driving comport of a vehicle.

The present invention provides a tilt hinge configured so that friction torque members accommodated in a leaf spring housing can be visually checked from outside and an electronic apparatus using the tilt hinge. The tilt hinge pivotally couples a first member to a second member and includes: a holder attached to one of the first and second members and including a leaf spring housing; a shaft attached to the other of the first and second members and rotatably supported by the leaf spring housing; and a plurality of friction torque members accommodated in the leaf spring housing and generating a friction torque when the holder or the shaft rotates. The friction torque members include a friction torque member that is constrained from rotation by the holder and a friction torque member that is constrained from rotation by the shaft. A friction torque is generated between the friction torque member fixed to the holder and the friction torque member fixed to the shaft when the holder and the shaft rotate relatively to each other. The leaf spring housing is provided with a notch portion through which all or some of the friction torque members accommodated in the leaf spring housing can be visually checked from outside.

A fastening device for fastening a first component B1 to a second component B2, with automatic compensation of tolerances in the distance S between the first component B1 and the second component B2. The fastening device includes a holding element and an adjusting element. A carrying element is provided on the adjusting element, the carrying element having a ring which is spring-loaded in the axial direction of the adjusting element, and in which a carrying element includes a carrying element thread and an overcomeable carrying element thread blocking means.
