Abstract: A process for producing a tape-like material uniformly containing highly pure single-walled or multi-walled carbon nanotubes with a high density highly pure single-walled or multi-walled carbon nanotubes; a high-performance field emission electrode including the tape-like material; and a process for producing the field emission electrode. For synthesis of carbon nanotubes by arc discharge, an inert gas or inert gas-containing mixed gas is jetted onto a cathode (2) comprising a carbon material from the inside (11a) of a hollow electrode (11) used as an anode, and simultaneously an arc is generated to form a path of arc discharge along the stream of the gas. Consequently, the cathode spot is prevented from irregularly moving, and thus highly pure carbon nanotubes can be produced. At the same time, by relatively moving both electrodes so as to move the cathode spot of the arc (3) on cathode, the synthesized carbon nanotubes are formed into a tape.

Abstract: An AC component of the photodetector includes two quasi-sine waves in a cycle of phase-modulation. T.sub.1 and T.sub.2 are time lengths of the quasi-sine waves. When a fiber coil is rotating, T.sub.1 differs from T.sub.2. The difference between T.sub.1 and T.sub.2 is in proportion to an angular velocity of the fiber coil. This invention obtains the angular velocity by measuring time durations T.sub.1, T.sub.2 or both T.sub.1 and T.sub.2. Zero-crossing detection defines the moments of the beginning and the end of T.sub.1 and T.sub.2. Since this gyroscope depends on the measurement of time lengths, it is fully immune from the fluctuation of light power due to the light source, or the fluctuation of the gain in the electric circuit.

Abstract: An optical fiber type polarizer comprises a first optical fiber constituted by a birefringent optical fiber wound at a predetermined winding radius and having winding start and end fixed to each other by an adhesive, the first optical fiber having short extra portions respectively extending from the winding start and end, and the length of each of the short extra porions being at least as small as the predetermined winding radius. The optical fiber type polarizer further comprises a second optical fiber spliced to one of the short extra portions of the first optical fiber, and a third optical fiber spliced to the other of the short extra portions of the first optical fiber.

Abstract: A fiber-optic gyroscope has a polarizer, a fiber coil and couplers. A light beam is polarized, divided into two beams and introduced into the fiber coil. Two depolarizers are provided; one between a light source and a polarizer, the other between the fiber coil and a coupler. To clarify the condition for avoiding interference between two depolarizers is a purpose of this invention. Four birefringent materials A, B C and D should satisfy inequalities;.vertline.P.sub.a B.sub.a L.sub.a +P.sub.b B.sub.b L.sub.b +P.sub.o B.sub.o L.sub.o +P.sub.d B.sub.d L.sub.d .vertline.-B.sub.5 L.sub.5 >Cwhere P.sub.a, P.sub.b, P.sub.o, and P.sub.d are triplet factors which take one of -1, 0 or +1 independently, B.sub.a, B.sub.b, B.sub.o and B.sub.d are birefringence and L.sub.a, L.sub.b, L.sub.o and L.sub.d are lengths of A, B, D and D. B.sub.5 L.sub.5 is extra birefringency of the fiber coil or couplers.

Abstract: A fiber-optic gyroscope having a single mode fiber coil for sensing the rotation suffers from drift or fluctuation of scale factor of the output signals owing to spontaneous rotation of polarization of beams propagated in the fiber coil. Thus, two depolarizers are required in front of and at the back of the polarizer to avoid the fluctuation. The depolarizer of prior art consists of two birefringent materials twistedly connected with each other at an about 45.degree. inclination angle between the principal axes of one and the principal axes of the other. A conventional fiber-type depolarizer has two polarization maintaining fibers connected together. A new, simplified depolarizer is proposed. The depolarizer is built by gluing a polarization maintaining fiber to an end of the polarizer with an about 45.degree. inclination angle between the principal axes of the fiber and the principal axes of the polarizer.

Abstract: A method for controlling a penetration bead, in an automatic one-side gas shielded arc welding wherein the backing material is adhered to the back of work pieces along a weld line and the welding is effected automatically from the surface side of the work pieces, comprises: putting an electrically conductive material on the surface of the backing material in the longitudinal direction; detecting a voltage between the work pieces and the electrically conductive material during the welding and controlling the voltage to be a predetermined reference voltage. The voltage is controlled by comparing the reference voltage and the detected voltage to obtain their difference and by correcting a speed of a travelling carriage which corresponds to the difference voltage to let the detected voltage be equal to the reference voltage. The electrically conductive material is one selected from a metallic foil tape, a metallic net and a wire.
