Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To achieve the light weight of a tire and improvement of hydro- planning resistance without deteriorating abrasion resistance and cornering power.

IPC: H04L12/24
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To facilitate coping with when a line has been in failure and to shorten communication interruption time in the line failure. SOLUTION: When a slave station S3 does not make a response to regular communication from a master station ML when the failure occurs in a circuit block diagram showing a master station search system, it is necessary to judge the failure to be instantaneous or continuous. Thus, trial communication for the prescribed number of times is executed from the master station ML to the slave stations S1, S2.... Then, a search signal is transmitted from the master station ML to the slave station S1. A response call (both systems responses to search signal) is given from the slave station S1 by the search signal and the master station ML and the slave station S1 are judged to be normal. In the case of a sequential search system, the station S2 is normal, the slave station S3 is abnormal and a failure part is judged to exist between the slave station S2 and the slave station S3.  In the case of an intermediate search system, the slave station S3 is abnormal and the slave station S2 is normal and the failure part is judged to exist between the slave station S2 and the slave station 3.

Filed: 1991-12-26
Abstract: PURPOSE:To provide the manufacturing method of a semiconductor element, wherein the diffusing step for forming a deep well and the outward diffusing step of dissolved oxygen can be performed as the common step. CONSTITUTION:Before well diffusion, the initial annealing is performed for 1 hour at 1,250 deg.C, which is higher than the outward diffusing temperature of dissolved oxygen. Deposition nucleuses up to deposition nucleuses, which are larger than deposition nucleuses that can be dissolved at 1,150 deg.C, are dissolved beforehand. Thereafter, annealing is performed for 14 hours at 1,150 deg.C. Thus, the well diffusion and the outward diffusion of the dissolved oxygen are performed at the same time. When the deposition nucleuses having the size that is growable at 1,150 deg.C are dissolved beforehand in this way, defects caused by the deposition of oxygen do not occur on the surface of the substrate even if the well diffusion and the outward diffusion of the dissolved oxygen are performed for the long time of 14 hours at 1,150 deg.C. The diffusing step for forming the deep well and the outward diffusing step of the dissolved oxygen can be used as the common step.
