Abstract: An LED is disclosed in which an optical cavity of the LED, which includes an active layer or region (15) and confining layers (14,16), is within a resonant Fabry-Perot cavity. The LED with the resonant cavity, hereinafter called Resonant Cavity LED or RCLED, has a higher spectral purity and higher light emission intensity relative to conventional LEDs. The Fabry-Perot cavity is formed by a highly reflective multilayer distributed Bragg reflector (DBR) mirror (13) (R B  ≧ 0.99) and a mirror with a low to moderate reflectivity (R T  ≅ 0.25-0.99) formed, for example, by the interface between a contact layer (17) and air in an aperture (19) in a top electrode (18). The DBR mirror, placed in the RCLED structure between the substrate (12) and the confining bottom layer (14), is used as a bottom mirror. Presence of the less reflective top mirror above the active region leads to an unexpected improvement in directional light emission characteristics. The use of a Fabry-Perot resonant cavity formed by these two mirrors results in optical spontaneous light emission from the active region, which is restricted to the modes of the cavity. While the bottom DBR mirror reduces absorption by the substrate of that light portion which is emitted toward the substrate, the two mirrors of the resonant cavity reduce the isotropic emission and improve the light emission characteristics in terms of a more directed (anisotropic) emission.

The compound includes 0.004at.% to 1.0at.% each of at least one halogen element selected from the group consisting of fluorine, chlorine, bromine and iodine. Alternatively, to provide a Ti-Al system intermetallic compound with oxidation resistance, the surface of the Ti-Al system intermetallic compound is heated to 800°C to 1125°C in a mixture of gas including 2ppm to 1% by volume of at least one halogen element selected from the group consisting of fluorine, chlorine, bromine and iodine, and also including 0.1% by volume or more of oxygen. Thus, a dense aluminum oxide film is formed on the surface of the intermetallic compound. Alternatively, to form the dense aluminum oxide film, at least one halogen element is first disposed on the part providing the oxidation resistance of the intermetallic compound, and heated for 0.2 hour or longer at 800°C to 1125°C. In this case, the halogen amount should be between 0.002 mol/m² and 2 mol/m².

Abstract: The object of the invention is to subject thermoplastic film webs (5) to a defined shrinkage, within the biaxial stretching process, with the application of small adjustment forces for changing the division and position of the clip chain and tenter clip (2) and to provide a device for carrying out the process. According to the process, this is carried out essentially in that   1. in the inlet region and/or heating region of the stretching machine, the division of the clip chain is varied in a manner known per se so as to reduce the spacing between the individual clip bodies and simultaneously a positional variation of the tenter means (18,19) receiving the film web edge is carried out to take up the material excess resulting from the spacing reduction,   2. the films are transversely stretched, 3. the positional variation of the tenter means in the fixing region is cancelled and, 4. after the film web edges are released, the shrinkage division is cancelled.   A device for this purpose consists of a clip chain whose tenter clips (2) are equipped with means, known per se, for divisional variation and the tenter clips are designed as pivot clips or at least the tenter means (18,19) within the clip are positionally variable. <IMAGE>

Abstract: A caliper logging sonde is provided having a plurality of sensing fingers each of which is pivotally mounted to the sonde and movable with respect to the sonde in response to variations in the internal dimensions of a wellbore tube through which the sonde passes. An electrical signal which is proportional to variations in the internal dimensions of a wellbore tube is determined at regular time intervals at a series of points around the circumference of the wellbore tube. A maximum and minimum dimension for each point around the circumference of the wellbore tube during a selected time interval is temporarily stored and thereafter transmitted to the surface at regular intervals. A high density array of sensors is provided by utilizing a transducer plate having a large number of cylindrical apertures disposed around the circumference thereof. Thimble members, each having an internal chamber and an elongate body narrower than the cylindrical aperture are fixedly inserted into one end of each of the detector plate apertures while an associated electrical coil is inserted into each aperture from the other end, surrounding the elongate body. Movable magnetic rods within the internal chamber of each thimble are then variably positioned in response to movement of the sensing fingers and the variable inductance of each electrical coil is then utilized to produce an electrical signal proportional to variations in the internal dimensions of the tube under measurement.
