Abstract: PURPOSE: To ease a stress concentration on the end surface of a cushion rubber layer by providing a groove having specified width and depth at a predetermined position in the circumferential direction of a tire on the end surface of a new tread part of a vulcanizer which is attached to a casing by an adhesive with a cushion rubber layer interposed therebetween.  
     CONSTITUTION: A reclaimed tire is obtained by attaching with an adhesive a new vulcanizer tread part 2 to the casing 4, from which an old worn-out tread part is removed, with a cushion rubber layer 3 interposed therebetween. The new tread 2 has a groove 5 on the both side end surfaces in the circumferential direction of the tire. In this instance, the length T 2  from the inner peripheral edge b of the cushion rubber layer 3 to the upper limit edge c of the groove 5 and the length T 1  from the edge b to the lower limit edge a of the groove 5 are respectively designed to be not more than 75% and 25% of the thickness T of the tread 2. Further, the groove 5 is designed to have a depth D in the range from 50% to 200% of the length T 1  and a width W of 1.0mm or more. Such a construction works to ease the stress concentration on the end part of the cushion rubber layer 3, resulting in less occurrence of cracks therein.

Abstract: PURPOSE:To prevent generation of sintering failure in both edge parts of a pallet, by feeding fine grain-like return ores between a pallet side wall and a specific interval, when charging sintered materials onto the pallet of a sintering machine. CONSTITUTION:When charging sintered materials onto a pallet of a sintering machine and sintering them, as for the sintered materials being in the vicinity of the pallet side wall, a sufficient sintering reaction does not occur since its gas permeability and temperature drop are large at the initial stage of sintering, comparing with those of the sintered materials of the center part, and deterioration of a quality such as a drop of cold strength of sintered ores, etc. occurs. In order to prevent said phenomenon, a partition plate 5 having width of >= 20mm. is provided on the inside from a side wall 7 of the sintering machine, also a blind great bar 8 is provided, return ores 6 of fine grains of <=2mm. are  charged between the partition plate 5 and the side wall 7, and regular sintering materials 11 are charged into the center part. In this way, gas permeability of  the materials in both edge parts of the pallet becomes equal to that of the  center part, and a drop of yield of sintered ores caused by sintering failure does  not occur.

IPC: H04L29/06
Filed: 1987-05-27
Abstract: PURPOSE:To improve transmission efficiency by providing a packet memory corresponding to each of the priority given to each packet, on both a transmission system and a reception system. CONSTITUTION:When a second packet whose priority is high is inputted from an input signal line 11, and written to a memory 110-n, a transmission system 100 suspends the transmission of a first packet, and starts the transmission of a second packet. In this case, a flag adding circuit 120 adds a packet delimiting flag to the second packet and sends it out to a transmission line 30. A reception system 200 detects its flag by a flag detecting circuit 220, suspends write and read-out to and from the memory 210-1 of the first packet which is receiving, and writes the second packet to a memory 210-n. Also, it is read out and sent out to an output signal line 22. Subsequently, the remaining part of the first packet which has been suspended is read out of the corresponding memory 110-1, and its transmission is started continuously after the regular flag of a termination of the second packet. In such a way, the transmission efficiency can be improved.
