    • A method for manufacturing an optical fiber array by connecting bare fibers to connection elements in a facing arrangement, comprising a step of aligning a plurality of bare fibers using a bare-fiber guide; a step of bringing a flat member into contact with the aligned bare fibers, tacking the bare fibers onto the flat member by direct or indirect bonding means while keeping the bare fibers sandwiched between the bare-fiber guide and the flat member, and separating the bare fibers and the bare-fiber guide thereafter; and a step of forming a coating of uncured material on the external peripheral surfaces of the tacked bare fibers and on the flat member exposed between the bare fibers, curing this material, and bonding the bare fibers to the flat member. This method dispenses with the need to provide a bare fiber guide member and allows manufacturing costs to be reduced.

    • An optical fiber guide structure used in industrial applications and a method of fabricating this structure. The optical fiber guide structure is excellent in dimensional accuracy, produces only small connection losses, and facilitates axial alignments and positioning. The method is initiated with preparing a silicon single-crystal substrate having a face of (110) orientation. An etching stopping layer, an epitaxial silicon layer, and a masking layer of silicon oxide are successively formed on the substrate. A photoresist is applied to the surface of the masking layer. Then, a development step, an etching step, and a peeling step are carried out. Thus, a substrate provided with rectangular grooves extending parallel to a (111) plane of the substrate is fabricated.

    • A scanning electron microscope capable of producing a stable image even if an automated focusing operation is being performed. The microscope has a secondary electron detector, a vertical scanning signal generator, and an image memory connected with a CRT. The output signal from the detector is supplied to the image memory via an amplifier and an A/D converter and also to an integrator via a filter circuit and an absolute value circuit. The specimen is scanned to produce an image and is substantially simultaneously scanned to gather data for adjusting the focus by stepwise adjusting the objective lens current. The stepwise adjustment of the objective lens takes place only during scanning to gather data.

    • An automatic focusing apparatus incorporated in a scanning electron microscope. The focusing apparatus permits accurate focusing even if a very uneven specimen surface is observed. The apparatus has a secondary electron detector. The output signal from this detector is supplied to a peak-holding circuit via a low-pass filter. The greatest peak value of the signal is detected and stored in a memory whenever the electron beam makes a scan at each different focal length of the objective lens. This processing is performed concurrently with integration of the output signal from the detector. This set of operations is repeated for all focal lengths. Data in the memory are compared with each other by a comparator, and the greatest peak value is found. Data about the focal length providing the greatest peak value is supplied as a reference signal to another comparator. In response to this data, data about several focal lengths close to this focal length are read from the memory and compared with each other. The focal length which makes the output value from the integrator maximal is selected from these focal lengths. The exicting current fed to the objective lens is determined according to data about this focal length.

    • A drawing head 11 of a pens exchanging mechanism has a pair of stationary arms 12 and 13 attached at one edge of a drawing head and a pair of rotary arms 14 and 15 pivotably attached at opposite edge of the head. In order to hold stably and surely the writing instrument 10, a spring force of the lower rotary arm 15 deflecting toward the stationary arms 12 and 13 is designed to have a strong one. When the drawing head 11 comes near a stocker in order to carry out writing instruments exchanging operation between the stocker 19 and the drawing head 11, an extruding arm 18 on the lower rotary arm 15 hits a securing member 24 installed on the stocker 19. Further movement of the drawing head 11 rotates the rotary arm 15 and the rotary arm 15 goes away from the writing instrument 10.
