Abstract: A pulley structure having a first rotating member that is rotatable around a first axis. A second rotating member is rotatable around the first axis and in at least partial axial coincidence with the first rotating member. A spring containing chamber is defined between the first and second rotating members. A spring, having axially spaced first and second ends defined by coils, extends around the first axis. At least one coil at each of the first and second axially spaced ends of the spring is radially biased relative to the first axis to thereby be frictionally held against each of the first and second rotating members to thereby allow forces generated by relative rotation between the first and second rotating members to be transmitted through the spring.

Abstract: A swash plate type hydraulic pump or motor comprises first and second swash plates which move reciprocally while opposing first and second pistons, so as to expand and contract a volume chamber according to rotation of a cylinder block. Drive pistons push on the swash plates from behind, causing the first and second swash plates to tilt, respectively. A tilt angle control valve controls the tilt angles of the swash plates by selectively increasing drive pressures that are guided to the drive pistons. A port plate is provided in a sliding portion between the first swash plate and the first piston. The port plate rotates integrally with the cylinder block and guides high and low pressure side hydraulic fluid, which flows through the supply and discharge ports provided in a sliding surface of the first swash plate, to the volume chamber via an inner portion of each first piston.

The laser diode module is formed by optically aligning a lens formed fiber disposed within a ferrule to a laser diode element. Ferrule fixing parts are utilized to hold the ferrule in place and are secured in position using a YAG laser welding process.

Abstract: A semiconductor laser module 1 having a package 2 containing a semiconductor laser device and lead pins 28 provided on both the side surfaces of the package 2. Since a base end portion of the lead pin 28 is fixed to the side surface at a position higher than the bottom surface of the package 2, the lead pin 28 can be laterally bent at a position higher than the bottom surface. Therefore, the semiconductor laser module 1 can be mounted on the surface of the wiring board 32 while the bottom surface of the package 2 is in close contact with the wiring board 32. Thus, since a heat radiation path from the bottom surface of the package 2 to the wiring board 32 is secured, it is possible to reduce the instability in the operating characteristic of the semiconductor laser device due to the thermal effect.

Abstract: An optical connector ferrule is equipped with a fiber insertion hole composed of an introductory hole, an intermediate hole, and minute holes. The introductory hole has a sectional area, which allows insertion of the coated portions of optical fibers. The intermediate hole has a sectional area which does not allow insertion of the coated portions of the optical fibers but which allows insertion of bare fibers exposed in front of the coated portions. Each of the minute holes has a sectional area, which allows individual insertion of each of the forward end portions of the bare fibers inserted into the intermediate hole. Thus, the insertion length of the optical fibers in the fiber insertion hole is uniquely determined. In particular, the insertion length of the coated portions can be set a predetermined length easily and reliably.

Abstract: A semiconductor laser module contains a wavelength selective feedback mechanism that has a center wavelength positioned a predetermined wavelength separation away from a peak gain curve of multiple output modes of light produced by a semiconductor laser contained in the module. In particular, the amount of separation between the center wavelength of the wavelength selective feedback mechanism is set such that modes occurring a predetermined wavelength separation on either side of the center wavelength, are on a same side of a gain curve of the semiconductor laser, with regard to a wavelength in which peak gain is observed. With lasers that have ripples in a characteristic gain curve thereof, the bandwidth of the wavelength selective feedback mechanism is set so that the local peaks of the gain curve decrease (or increase) monotonically therethrough. When the ripples are absent in the gain curve, the slope of the gain curve remains monotonic throughout the reflectance bandwidth.
