摘要:
An optical function module comprises a collimator block having a substrate, at least two collimators disposed on the substrate in confronting relation to one another for collimating a light flux directed along a preselected path between the collimators, and support members each for supporting a respective one of the collimators on the substrate. An optical function device is removably connected by a connecting structure to the collimator block so that the optical function device is positioned along the preselected path of the light flux between the collimators.

An optical switch has an input section for inputting a light beam and movable optical members each comprised of a piezoelectric actuator for inputting the light beam from the input section and for individually switching an optical path of the light beam. Each of the piezoelectric actuators has a piezoelectric body for undergoing oscillating movement and a movable body frictionally driven by oscillating movement of the piezoelectric body. A driving control device drives the piezoelectric bodies of the piezoelectric actuators and controls positions of the piezoelectric bodies to switch the optical path of the light beam. An output section outputs the light beam from the piezoelectric actuators.

The present invention provides a lid or a case for a sealed package, which is provided with a frame-shaped soldering material on its face to be joined, wherein the frame-shaped soldering material is formed of aligned ball-shaped soldering materials having particle sizes of 10 to 300 μm. This lid or case can be manufactured by the steps of: (1) forming a droplet from the soldering material in a molten state; (2) discharging the soldering material which has been formed into the droplet onto the face to be joined of the lid or the case to fix the ball-shaped soldering material on the face; and (3) repeating the steps (1) and (2).

An optical fiber connector has a stop ring having an end portion having an outer periphery and an optical fiber cable having a strength member extending from an end thereof. An adhesive material is disposed over the end portions of the stop ring and the optical fiber cable so that at least a portion of the strength member of the optical fiber cable is embedded in the adhesive material. A heat-shrinkable tube has an inner surface and is disposed on the adhesive material so that the portion of the strength member is disposed between the inner surface of the heat-shrinkable tube and the outer periphery of the stop ring.

The present invention is to provide low insertion-force connector terminals. A self-assembled monolayer is deposited on the surface of the connector terminals. The deposited connector terminals do not require a special lever for adjusting contact pressure. The connector terminals are easily manufactured without cost-up and made small size. They do not increase contact resistance and they are easily connected to each other with low insertion force so that they are applied to the connectors of vehicles.

A highly reliable optical communications equipment is offered, which can control light more accurately than heretofore (i.e., less restrictions are imposed on the amount of attenuation and on the resolution) and which is equipped with a latching function. The optical communications equipment includes a piezoelectric actuator, a moving body moved by the piezoelectric actuator as a drive source, a multi-coating filter for controlling light that is a signal medium by movement of the moving body, a drive circuit for controlling the position of the multi-coating filter via the actuator, and a control circuit. The piezoelectric actuator uses bending vibrations produced in a piezoelectric vibrating body as a power source. If the moving body is not moved for a given time, the control circuit sends a function keeping signal to drive the actuator to such an extent that the moving body does not move. Thus, the function of the actuator is maintained.

To provide a ferrule tubular body and a ferrule which is free from a fear that the end face of the ferrule may be roughened, which can eliminate an eccentric adjustment process performed after an optical fiber is fixed, and which can attain the optical connection less in insertion loss. An indicator section 1d, 3a, 1e or 3b making it possible to observe an eccentric direction of a though-hole to which an exposed optical fiber end portion is inserted to be held is provided on the outer surface of a ferrule tubular body 1A, 1B, 1C, 1D and/or the outer surface of a flanged member 3A, 3B, 3C, 3D securely fixed to the rear end of the ferrule tubular body 1A, 1B, 1C, 1D.
摘要:
A brazing material which can be melted at a suitable temperature at which damage is not given to a device inside a package upon sealing, and besides the brazing material is not remelted, e.g., upon mounting to a board, and which has a low temperature difference between a liquid and a solid. The brazing material is made of a Au—Ga—In ternary alloy, wherein weight concentrations of the elements lie within a region of a polygon with a point A (Au: 90%. Ga: 10%, In: 0%), a point B (Au: 70%, Ga: 30%, In: 0%), a point C (Au: 60%. Ga: 0%. In: 40%) and a point D (Au: 80%, Ga: 0%. In: 20%) as vertexes. excluding lines on which In and Ga become 0%, in a Au—Ga—In ternary phase diagram.
摘要:
This method for inhibiting damage due to arc between electrical contacts involves the spreading of a grease composed of from 70% by weight to 95% by weight of a base oil and from 5% by weight to 30% by weight of a thickening agent and additives over a pair of electrical contacts in a circuit which causes terminals to move relative to each other so that they are disconnected from each other, whereby damage on the contact area due to arc occurring when the electrical contacts are isolated from each other is inhibited. As the thickening agent there is preferably used an organic bentonite. As the base oil there is preferably sued an ester oil, glycol oil or poly-α-olefin. The base oil preferably has a low density to reduce arc energy.
