Abstract: PURPOSE:Coal tar pitch, as a starting material, is modified and made into short fibers, then the length of the fibers is adjusted, the resultant fibers are preoxidized, and calcined to produce carbon fiber that is suitably used to reinforce artificial graphite for electrodes, in low costs. CONSTITUTION:Coal tar pitch, as starting material, is treated to remove substances insoluble in solvents, them melted, pressurized and jetted from a nozzle or a high-pressures gas stream is made to act on melted tar drops which flow down through small holes on the feeding pipe by pressure or spontaneously to form fine fibers. The fine fibers are made to collide to baffle plates and the resultant fibrous pitch is conveyed with a air stream and preoxidized as they pass through the reaction tube.

Abstract: PURPOSE:To measure a distance by means of a non-modulation CW Doppler rader, by calculating a distance to an object to be measured after a radar sensing starting distance is decided based on a reflection reception power at a lever higher than the prescribed one and a power obtained after traveling at a prescribed distance. CONSTITUTION:A reception power level proportional to the quartic of a distance from a CW Doppler radar 1 is detected by a detecting circuit 5, and the rate of a change from a prescribed level set by a sensitivity setting circuit 6 is found by a comparison circuit 7 and given to a microcomputer 10 via an A/D converter 8. Meanwhile, a traveling distance information from an integrating circuit 3 integrating Doppler signals and a speed information from a counter 4 are also impressed on the computer 10, and thereby a sensing starting distance corresponding to the effective reflection area of a body to be measured is decided based on a rate of a change in the reception power. Thereafter the traveling distance information is subjected to subtraction or addition according to the speed information, and thus measurement of a distance can be performed by using a non-modulation CW Doppler radar requiring no modulation and having a simple constitution.

Title: Master cylinder
Inventor: TAKAHASHI TOSHIYUKI
IPC: B60T11/16
Filed: 1986-05-01
Abstract: PURPOSE:To prevent shrinkage and improve circularity providing collectively ribs for connecting a cylinder proper to a fitting flange member at positions orthogonal with outward flanges in one direction. CONSTITUTION:Ribs 72 for connecting a cylinder proper 12 to a fitting flange member 60 are collectively provided at positions orthogonal in one direction with outward extended flanges 62 and 64. In a forming process, shrinkage due to cooling causes a force to work from the thick outward extended flanges 62 and 64 upon a cylindrical part 74. This working force is relatively large at a dumbbell shape part 60a of heavy thickness. As the rib 72 is not fitted to the root of the dumbbell part 60a, said working force is absorbed, while causing only the slight deformation of the cylindrical part 74.
