摘要： In a variable valve gear for an internal combustion engine provided with a camshaft phase change mechanism for variably controlling opening and closing timings of an intake valve, the camshaft phase change mechanism and a variable valve lift mechanism are controlled so that the closing timing of the intake valve is advanced beyond a predetermined range T1 including a bottom dead center when a load L of the internal combustion engine is less than a first predetermined value L1 and that the closing timing of the intake valve is delayed beyond the predetermined range T1 when the load L of the internal combustion engine is not less than the first predetermined value L1.

摘要： An optical transceiver with the optical receptacle tightly assembled with the optical subassemblies is disclosed. The optical transceiver provides a metal shield. The optical subassembly provides a pair of flanges and a neck between the flanges. The metal shield has a cut with the U-shape and a rib formed along the edge of the U-shaped cut. The metal shield is put between the flange and the optical receptacle so as to crush the rib, which causes a repulsive force against the flange to set the optical subassembly on the optical receptacle without loose.

摘要： An SFP transceiver with two subassemblies each having an optical coupling member with a polygonal cross section is disclosed. The polygonal cross section has a flat surface facing the flat surface of the other subassembly. Between flat surfaces is put with a metal partition plate that comes in contact with a metal frame and a metal cover of the transceiver. Two sub-assemblies are electrically shielded by the partition plate, and the polygonal cross section of the subassembly makes the total width of the two assemblies added with the thickness of the partition plate minimum.

摘要： An optical transceiver that provides an inner metal cover in addition to a metal cover and a frame is disclosed. The inner cover includes a ceiling, a front skirt bent downward at a front edge of the ceiling, sides bent downward at both side edges of the ceiling, and a pair of arms extending rearward from respective side ends of the ceiling. The ceiling makes an obtuse angle with respect to the front skirt when the arms are not assembled with the frame, and shapes in convex protruding outward when the metal cover is not assembled with frame and. Assembling the inner cover and the metal cover with the frame, the inner cover comes in securely contact with the metal cover.

摘要： An optical transceiver with an optical receptacle separated from the frame is disclosed. The optical transceiver comprises an optical sub-assembly, an optical receptacle and a frame. The optical receptacle, which is set between the side walls of the frame, and assembled therewith by fastening a screw between the optical receptacle and the side wall of the frame. Inserting the screw into the screw hole, the optical receptacle is forced to move rearward which securely fixes the optical subassembly assembled with the optical receptacle between the optical receptacle and the saddle provided in the frame.

摘要： A pluggable optical transceiver with an enhance EMI tolerance is disclosed. The optical transceiver provides an electrically conductive receptacle, a ground member made of metal sheet, and a cover also made of metal sheet. The ground member is assembled so as to surround a periphery of the receptacle. The cover provides a first bridge in a front portion thereof, while, the ground member provides fingers and a second bridge connecting the fingers in the tip portion. Fully setting the optical transceiver in the cage, the finger comes in contact with the inside of the cage and the first bridge comes in securely contact with the second bridge so as to shield a gap between the transceiver and the cage.
