摘要： A fiber-optic polarizer made by a process comprised of providing a substrate, coupling or embedding an optical single mode fiber to the substrate, making a narrow trench across the fiber at an angle, thereby bifurcating the fiber core into a first fiber core end and a second fiber core end, inserting and securing a thin polarizing material of a monolithic, non-laminated structure into the narrow trench, such that a light spot size emitted from a first fiber core is completely encompassed by the polarizing material, and the light spot size emerging from the polarizing material is substantially collected within the mode field diameter of a second fiber core. The narrow trench having a width of about 30-50 &mgr;m, and the polarizing material having a thickness of about 15-50 &mgr;m. The polarizing material having a monolithic composition. Moreover, the inventive polarizer has good reliability in terms of mechanical durability and weathering, since polarizer is fabricated on substrate in which optical path is entirely sealed. This is a process that eliminates the need to use specialized fibers or fibers that are specially treated such as those with thermally expanded cores (TEC). The process is also an alignment-free process that enables easier and faster mass-fabrication. This process produces multiple polarizers at a time.

摘要： When plug is fitted to adapter, optical fiber is inserted to an alignment hole for the optical fiber. By providing a taper at the entrance thereof, even if the tip of the optical fiber is deviated from the central position, the deviation is absorbed to make it possible for the optical fiber to be inserted smoothly. When two plugs is fitted to adapter, the tip of one optical fiber is confronted with the other one in the alignment hole, and excessive length L.sub.1 -L.sub.2 is pushed into the two optical fiber-bending spaces with a suitable distribution, thus the optical fiber buckles therein. The end face of the optical fiber is subjected to flat surface-polishing, removal of ripples after being cleaved, or chamfer grinding after being cleaved. The buckling portion of the optical fiber is coated with carbon or the like.

摘要： In a semiconductor memory device having plural pairs of bit lines and plural sense amplifiers, a gate electrode of a sense amplifier transistor for sensing potential of a first side of a first bit line pair is formed with an extension portion extending under and along the first side of a second bit line pair. A capacitance C.sub.B formed between the extension of the gate electrode and the first side of the second bit line pair is determined to be equal or larger than capacitance C.sub.A formed between the first side of the first bit line pair and the gate electrode. Since the potential of the first side of the bit line pair fluctuates roughly in phase with that of the second side of the same bit line pair, a harmful influence due to interference noise can be reduced, without increasing the chip layout area, by only modifying the shapes of the gate electrodes of the sense amplifier transistors.
