Title: Anti-skid control device
Inventor: SHOBU MASAYA
IPC: B60T8/172
Filed: 1995-04-27
Abstract: PURPOSE: To avoid mis-determination of gear engagement as a bad road to prevent execution of improper anti-skid control. CONSTITUTION: In the case of two-wheel driving, gear engagement is determined as detected when a rotation speed increase/decrease frequency of a drive wheel is larger than that of a driven wheel by a set frequency difference or more (S305, 306). In the case of four-wheel driving, gear engagement is determined as detected when an estimated car body speed is less than a set car body speed (S308), and in the case where a road surface friction coefficient is determined to be low because of a small car body deceleration during anti-skid control (S309, 310).  In a normal condition where gear engagement is not detected, in the case where wheel rotation speed increase/decrease frequency is large, it is detected as a bad road, and control conditions of anti-skid control are changed to control brake cylinder pressure to be higher than that on a good road, while if gear engagement is determined as detected, the control conditions are not changed.

Title: Manufacture of high purity glass article
Inventor: ARAN KAATEISU BEIRI
IPC: C03B37/025
Filed: 1981-07-03
Abstract: A method of making solid glass articles by the flame hydrolysis technique. A thin stratum of low viscosity glass soot is applied to the surface of a mandrel. First and second coatings of glass soot are deposited on the surface of the thin stratum to form a porous preform. The refractive index of the soot particles of the first coating is greater than that of the soot of the second coating, and the soot of the first coating has a viscosity lower than that of the second coating. The mandrel is removed, and the soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank. The glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process. The thin stratum, which preferably includes P2O5, smoothes over the damage caused by removing the mandrel and reduces or even eliminates seed formation at the axis of the resultant glass blank. The blank may be heated and drawn into a filament, or it may be sliced into optical windows, lenses or the like.

Abstract: PURPOSE:To decrease extra transmission lines in normal use and to eliminate an adverse influence upon transmission characteristics by providing a circuit which connects and disconnect internal circuits and test terminals nearby an interface circuit for transmission lines. CONSTITUTION:In normal use, test cable attachment/detachment detection parts 113 and 114 send signals for connecting switches 115 and 116 to B sides to the switches.
