摘要： PURPOSE:To facilitate simultaneous connection of multiple fibers at a low loss with good attaching and detaching workability by building in a pressure sleeve for intensifying the pressurizing force for elastically pressurizing guide pins toward the lower direction of the guide pin grooves of a groove base plate at the time of insertion of an optical connector ferrule. CONSTITUTION:An external clamping mechanism having the pressure sleeve 25 is provided in an optical connector adapter 20. The pressure sleeve 25 is adapted to elastically grip the optical connector ferrule 10 from above and below and to intensify the guide pin gripping force from the outside after the optical connector ferrule advances into the adapter 20 and the guide pins 3 are inserted into the inlets in the guide pin holes. The low-loss connection is enabled in this way and the need for handling the guide pins based on the push-pull functions is eliminated at all. The optical connector having the simple attaching and detaching workability is obtd.

摘要： PURPOSE:To eliminate the need for handling small side pins and to facilitate attaching and detaching operability by fixing guide pins to guide pin holding plates and forming the guide pin holding plates in such a manner that these holding plates can be finely adjusted easily in the direction perpendicular to the axis of the guide pins. CONSTITUTION:The guide pins 3 positioned in an adapter are fixed to the guide pin holding plates 2 positioned in the direction perpendicular to the guide pin axis in the central part of the longitudinal direction thereof. The guide pin holding plates 2 are housed in the holding plate housing part 6 in the adapter easily finely adjustably in the direction perpendicular to the guide pin axis while the holding plates are held substantially immobile in the axial direction of the guide pins. The guide pin 3 sides are inserted into the guide pin holes of an optical connector plug while the positions thereof are changed in this case. The need for handling the fine and small guide pins is eliminated in this way and the attaching and detaching operability is facilitated.

摘要： PURPOSE:To provide the optical connector which can be coupled to an external connector via an adapter on a back board by constituting an insertion guide in such a manner that the guide can be floated from a housing by a pressurizing spring. CONSTITUTION:A snap 18 for facilitating the coupling to a substrate is provided in the lower part of the housing 13 for gripping the insertion guide 12. The ferrule pressurizing spring 14 which is positioned between the rear end part 11a of the ferrule 11 and a pressing ring 17 mounted behind the same and presses the ferrule 11 in the axial direction is provided. The insertion guide pressurizing spring 15 which is mounted between the rear surface of a stopper 16 provided in the guide 12 and the housing 13 and pressurizes the guide 12 toward the housing 13 is provided. The housing is easily mounted to the substrate in this way and since the insertion guide floats from the housing, the coupling is possible even if the axis is misaligned vertically and laterally from the adapter on the back board.

摘要： PURPOSE:To prevent the electrification in a high-temp. state by forming a metallic film which discharges the charge electrified on an LiNbO3 substrate to the ground on the surface of the LiNbO3 substrate, on which surface waveguides are not disposed. CONSTITUTION:The LiNbO3 optical switch 10 is basically constituted of plural Ti waveguides 2 and electrodes 3 for switching on one surface of the LiNbO3 substrate 1 and is further constituted by having the metallic film 4 consisting of Cr-Au, Ti-Au, etc., on rear surface side in order to prevent electrification of the LiNbO3 substrate 1. The LiNbO3 is intrinsically the dielectric and is electrified simply by resting the same in the high-temp. state, for example, in about 50 deg.C environment. The state in which a voltage is impressed to the electrodes 3 is equivalently attained if the discharge to this electrification is insufficient. Namely, the switching characteristics vary with the electrification, but the electrification is obviated in spite of rising of the use environment temp. to about 50 to 60 deg.C and the good switching characteristics are obtd. by forming the metallic film 4 consisting of Cr-Au, Ti-Au, etc., on the rear surface and shorting the metallic film 4 to the ground. The LiNbO3 optical switch having the high quality is obtd. in this way.

摘要： PURPOSE:To enable chip carriers to be packaged in a high density, by providing two or more wire bonding layers and arranging sealing layers stepwise in upper and lower stages so as to decrease the carrying area of the carrier. CONSTITUTION:A chip carrier 10 is provided with a die pad 11, with two wire bonding layers 12 and 13 and with sealing layers 14 and 15 which are arranged stepwise in the upper and lower stages. The bonding layers 12 and 13 are provided with a plurality of wire bonding pads 16 and 17, respectively, while the sealing layers 14 and 15 are provided with sealing pads 18 and 19, respectively. IC's 21 and 31 are received in the carrier 20 thus constructed and the carrier is sealed with a cap 35 while a sealing cap 26 is used as a die pad for the IC 31. In this manner, a plurality of IC's can be packaged three-dimentionally without increasing the carrying area of the carrier. Accordingly, such chip carriers can be packaged on a printed-circuit board in a high density.
