IPC: H01L33/00
Filed: 1988-02-18
Abstract: A laser structure with highly p-doped active material is described which has a particularly low linewidth enhancement factor a. Hence the emission linewidth of the laser structure 1 is relatively small. 
     The structure 1 shows a particular relationship between the photon energy E, the band gap energy Eg and the conduction band quasi Fermi level Efc of the active material which minimises a, the valence band being degenerate. These conditions can be used to design low a laser structures. 
     Structures according to embodiments of the invention are of particular application to directly modulated lasers or absorption modulators and also find application in coherent optical detection.

Abstract: A packing material having improved chemical resistance formed of poly(phenylene) sulfide and polytetrafluoroethylene fi­bers is provided. Each of the fibers may be treated with PTFE dispersion and, optionally, with graphite. The fibers can be knitted, braided or twisted together and the structure may be impregnated with a polytetrafluoroethylene based binder and lubri­cant. The resulting packing material has improved temperature characteristics, heat transfer characteristics, wear resistance, provides a dense impervious packing and is dimensionally stable in addition to the improved chemical resistance. A packing material prepared from fibers treated only with a PTFE dispersion is especially useful in the paper making industry and for other appli­cations wherein dark colored fibers are not permissible.

Abstract: In an apparatus for detecting whether or not an information signal is recorded on a storage disk, a light beam is allowed to scan an information track of the disk. The light beam is wobbled in a direction perpendicular to a longitudinal direction of the track (2) in response to a wobbling signal. A reproduced signal is derived from the light beam which was affected by the disk (1). A variation in amplitude of the reproduced signal is derived. A difference between the derived amplitude variation and the vibration signal is detected. A detection signal is generated which represents the detected difference.

Abstract: A pulse oximeter apparatus comprises a bandpass filter adapted selectively to exclude motion artefact from wanted signal. 
     In order to achieve this, the filter is initially tuned to the pulse rate. Moreover, as the pulse rate changes, the filter is so-adapted that its pass-band will track the pulse rate.

Abstract: A metallization scheme useful for integrated circuits uses a buffer layer (e.g., 5) to ensure that the etch back of a contact metal (e.g., 7), such as tungsten, deposited over the buffer layer, can be controlled to form a complete tungsten plug in a via while the tungsten on the dielectric is completely removed. Different etch rates of the buffer and contact materials ensure that, once the buffer layer is exposed, it etches rapidly and the contact material is not significantly etched.

Abstract: Conventional seals in molds for forming gaskets about glass preforms may deform against a glass preform and 
cause 
distorted molded gasket shapes and seal failure. The invention provides means to equalize stresses along the seals 
to solve 
the problem. The seal assembly cooperates with a mold to define a gasket forming mold cavity. Each seal 
assembly in­
cludes a sealing body (36, 42) having a sealing surface (38, 44) which faces and is adapted to sealingly contact the 
window 
assembly (30). The seal assembly also includes a first fluid filled bladder (41, 45) positioned between the sealing 
body and 
a bottom of the groove (39) in the mold section. A second fluid filled bladder (50) is positioned between the 
sealing body 
and a side wall of the groove to force the sealing body against the opposite side wall of the groove.

Abstract: A method for constructing superconducting structures from a number of superconducting sub-units (20-25; 30) by tessellation. This enables relatively large superconducting structures to be formed in a variety of different shapes and configurations. The superconducting sub-units (20-25; 30) may be used to form a planar surface or a curved surface and means (16, 13) are provided to enable an external current to be passed through the superconducting sub-unit (10) so as to drive a magnetic body levitated above the structure. This method of construction may also be used to construct superconducting solenoids and magnets (40) in the form of Bitter disks (35) and is particularly useful for constructing structures from the recently discovered high temperature ceramic superconductors.

Abstract: Blattwechsler für das zyklische Umschichten eines Stapels von Blättern mit einem Gehäuse und einem aus diesem herausziehbaren Schieber. Der Blattstapel wird von einer Federanordnung gegen ein im Gehäuse ausgebildetes Sichtfenster gepreßt. Bei der Bewegung des Schiebers führt der Andruck zu starker Reibung, die dadurch gemildert wird, daß an den Stellen, wo die Federkraft jeweils wirkt, reibungsmindernde Elemente zwischen dem Schieber und dem Gehäuse bzw. der Andruckanordnung vorgesehen sind. Abstract A sheet changer which cyclically changes the distribution of a pile of sheets comprises a housing and a drawer which can be slid out of the housing. The pile of sheets is compressed by a spring arrangement against a window arranged in the housing. When the drawer moves, the pressure causes excessive friction, which is reduced by friction-reducing elements arranged between the drawer and the housing or the compression arrangement at the points on which the force of the spring is exerted.

Abstract: The invention relates to an apparatus for treating cotton contaminated or imbued with honeydew. For this purpose, cotton flocks are fed into a microwave oven, in which the cotton flocks are heated by microwave energy, thus reducing the stickiness or tackiness of the honeydew such that there are no processing disadvantages on subsequent machinery. The microwave oven basically comprises a conveyor belt on which the cotton flocks are conveyed through a passage or channel provided with microwave generators. At the exit or outlet of the microwave oven the cotton flocks are transferred to an opening unit which transfers the cotton flocks into a feed chute or shaft.

Abstract: A flow switch includes a movable shuttle (30) enclosed within a bore having narrower and wider bore sections (14, 16). The shuttle (30) has a solid cylindrical portion (32) and a vaned portion (34). When there is no fluid flow from the inlet (12) to the outlet (18), the shuttle (30) rests on a part-conical portion (20) of the bore. When fluid pressure is applied at the inlet (12), the shuttle (30) is raised until the vaned portion (34) is partly within the wider bore section (16). Fluid can then flow through the spaces between the vanes in the vaned portion (34), and fluid flow is detected by the change in position of the shuttle (30). The shuttle (30) can be made magnetic, whereupon a magnetic sensing means (40) such as a magnetic reed switch can be used to detect fluid flow. This arrangement has the advantage that resistance to flow and pressure drop are minimal compared to previous designs.
