Abstract: A grooved cylindrical core or rod is conveyed in a state of elastic elongation, giving it excess length, through a distributing device and a die-plate. Optical fibers are each fitted in a respective groove of the rod at the entry of the die-plate. Downstream from the die-plate, the rod provided with the fibers passes through a zone in which there is a powerful electric field created by a ionization bar. Under the influence of the ionization, the fibers cling to the walls or bottoms of the grooves. This provides the drag necessary for stretching the fibers when they approach the rod.

Abstract: In a double air-fuel sensor system including two air-fuel ratio sensors upstream and downstream of a catalyst converter provided in an exhaust gas passage, an actual air-fuel ratio is adjusted in accordance with the outputs of the upstream-side and downstream-side air-fuel ratio sensors. A center value of an air-fuel ratio correction amount or an air-fuel ratio feedback control parameter calculated based upon the output of the downstream-side air-fuel ratio sensor is calculated by a learning control for regions defined by the period of the output of the upstream-side air-fuel ratio sensor, and an air-fuel ratio feedback control is initiated by using the center value stored for the current region when the engine enters into an air-fuel ratio feedback control state, or when the period of the output of the upstream-side air-fuel ratio sensor is transferred to a different region.

Each block includes first and second side engagement surfaces. When the continuous belt spans between the input and output pulleys, at least two different engagement points are defined between the blocks and the pulley. Each link includes first and second end portions, an intermediate portion, first and second connecting holes, an outer projection and an inner projection. The first and second connecting holes are defined within the first and second end portions. The outer projection projects from the first and end portion toward a lateral direction of the continuous belt.

Each link has a pitch line of the link which passes through center points of the first and second connecting holes.

Abstract: The invention relates to a navigational instrument for automatically controlling the stability of a mobile target, or locating the position of the target with respect to one of several reference planes. The arrangement includes a moving part A whose base G is weighted so that the moving part takes the form of an anchor which pivots about an axis B located on a fixed part fastened to or defined by the moving target. The base G of the moving part has two arms. In an AC embodiment of the invention, the arms are provided with electrically conductive windings and the fixed part includes two electrically conductive windings energized by alternating current. If the fixed part is tilted, one of the windings in the moving part will penetrate the fixed winding to a depth proportional to the tilt angle. At this point, an alternating current, proportional to the tilt angle, will be induced in the winding in the moving part.

A second damper mass having a cylindrical shape is disposed between the connection portion and the annular member, in an inner space of the cylindrical portion, concentrically with the cylindrical portion; is (f) a second resilient member disposed between the annular member and one axial end of the second damper mass, so as to secure the second damper mass to the annular member.

Abstract: A new water-swellable composition of a gelling agent based on hydrolyzed homo- or copolymers of acrylonitrile and of an inert metal oxide was synthesized. In the process, 1 to 22% of the nitrile groups were saponified to amide groups and 99 to 78% to alkali-metal salts. The obtained composition had a spongy structure and was characterized by high values with regard to both swelling capacity and swelling rate. Therefore it is particularly suitable for diaper manufacture and for agricultural use.

Abstract: The twin-tube type shock absorber wherein a piston-rod extends downward from a piston and penetrates a lower end portion of an outer shell. Pressurized gas in a reservoir chamber is positioned in an upper portion of the outer shell where the piston-rod does not penetrate the outer shell. Since a seal disposed between the piston-rod and the lower end portion of the outer shell is not exposed to the gas in the reservoir chamber, no gas leakage occurs through the portion where the piston-rod penetrates the outer shell. In addition, the piston-rod is connected to a member disposed on a wheel side of a suspension spring of a vehicle, so that vibrational characteristics of a vehicle body is improved and bubbling of a liquid in the outer shell is suppressed.

Abstract: A vibration isolating apparatus is provided with a liquid chamber which is capable of being expanded and contracted for the purpose of absorbing vibrations. The liquid chamber is partitioned into small liquid chambers by a resilient membrane, the chambers being communicated with each other through an orifice. Vibrations are transmitted to the small liquid chambers through a transmission shaft which extends through the resilient membrane and which is slidable relative to the membrane. Accordingly, even when the direction in which vibrations act changes, vibrations applied to one small liquid chamber are reliably transmitted to the other small liquid chamber. Thus, contraction of one small liquid chamber causes the other small liquid chamber to expand, and a liquid is forced to pass through the orifice while generating fluid resistance whereby the vibrations are absorbed.

Abstract: Silicon nitride sintered bodies are disclosed, which each consist essentially of Si, O, N, and at least two kinds of rare earth elements selected from Y, Er, Tm, Yb, and Lu the bodies comprising not less than 70% by weight of Si.sub.3 N.sub.4. The ratio of the molar amount of all the rare earth elements contained in the sintered body calculated as moles of Ln.sub.2 O.sub.3, Ln being a rare earth element selected from Y, Er. Tm, Yb and Lu divided by the molar amount of oxygen calculated as moles of SiO.sub.2 is within the range of from 0.4 to 1.3. The amount of oxygen calculated as moles of SiO.sub.2 is obtained by subtracting the amount of oxygen contained in all the Ln.sub.2 O.sub.3, all the rare earth elements contained in said sintered body being considered as molecules of Ln.sub.2 O.sub.3 from the amount of oxygen contained in the sintered body and converting the remaining amount of oxygen into moles of SiO.sub.2.
