Abstract: An optical switch includes at least one input optical semiconductor waveguide; two output optical semiconductor waveguides connected at a branch point to the input optical waveguide and diverging from the branch point with a preset angle .theta. (degree) therebetween; and a refractive index controlling section disposed in position on at least one of the output optical waveguides and apart from the branch point, for electrically pausing the refractive index of the output optical waveguide to be reduced. A light attenuating layer for preventing radiation mode light leaked from a portion near the branch point to the outside of the optical waveguide from being re-combined with guided mode light in the output optical waveguide is disposed between the two output optical waveguides.      The refractive index controlling section is formed so that a length from the physical branch point between said two output optical waveguides to an output end portion of the refractive index controlling section may be set equal to or larger than 100 .theta. 8/cos (.theta./2) µm.      A distance between the nearest portions of the refractive controlling sections of the output optical waveguides is set to be equal to or less than twice a spot size so as to improve the extinction ratio and excessive loss. The optical switch of this invention can be applied to a Y-junction type and X-junction type, and the refractive controlling section can be disposed on each of the branches or may be disposed on selected two of the branches. In the X-junction type optical switch, the refractive index controlling section may be adequately disposed on one of groups of branches which make an angle of (180°-.theta.°).

Abstract: ABSTRACT                    ANALYSIS OF DRILLING SOLIDS SAMPLES   A method of quantitative analysis of solids carrying drilling mud and removed from a drilling fluid circulating in a wellbore being drilled is described. The method comprises the steps of: sampling the removed solids, and analysing the sample to determine the density of the solids and their weight fraction, drying a known weight of the sample to constant weight so as to obtain the solids in the form of dry solids, and analysis of the latter by an infrared spectroscopy technique. The concentration of the substances in the removed solids is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers, or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment.
