Patent JP-2586978-B2 (JP)
IPC: G02B5/30
Filed: 1992-07-10
Granted: 1997-03-05
Abstract: Polarisation filter for delivering an output signal So containing only one (TE or TM) of the two polarisations (TE and TM) in an input signal Si, comprising an intermediate guide section (5) between an input section (A) and an output section (B). The output section (B) is a mode splitter having a monomodal output channel (3) for the output signal (So) and a monomodal dummy channel (4) which recedes beyond the interaction distance (D). The output channel (3) has a lower propagation constant than the dummy channel (4). The input section (A) having an input channel (1) and a dummy channel (2) is an inverse mode splitter which may be the mirror image of the output section (B). The guide section (5) is monomodal for one of the two polarisations and bimodal for the other polarisation. Both polarisations of the input signal Si entering via the input channel (1) are initially converted into first-order modes, of which only one is a guided mode of that conductor section and reaches the output section, where it propagates further along the channel having the lowest propagation constant. The first-order mode of the other polarisation escapes (6). <IMAGE>

Abstract: Speed-reducing mechanism characterised in that each planet gear (15) has on its central axis a cylindrical bearing surface (16) (internal or external) designed to centre itself on and react with a complementary cylindrical bearing surface (21) (external or internal, respectively) provided on a star-shaped planet-gear support (20) which, owing to the material from which it is made and its design, has sufficient elasticity in order constantly to press the teeth of the planet gears into the teeth of their respective disc, thus making it possible to take up the play inherent in the manufacture of this type of mechanism and also making it possible to absorb, without degradation, such excess loads as may arise, for example in the course of the use of the speed-reducing mechanism as an articulation for a vehicle seat.

Abstract: CD apparatus having a power-operated loading and ejecting device for the CD (1), a horizontal slot being provided on the front side of the apparatus housing, which slot is adjoined on one side by a guiding means (2), which serves as a curved rolling surface for the introduced CD (1) when the latter is driven diametrically with respect to a motor-driven friction wheel (3). At the end of the loading movement, the motor (4)/friction wheel (3) unit swivels to the side under the action at the same time of a gear wheel (10) and a curved rack (11) and actuates a lifting arm (12), the wedge-shaped end (14) of which raises the drive (16) to such an extent that the CD (1) rests on the turntable (6) and is pushed against a "Puck" (7), which fixes it. The functional steps proceed in the reverse order during ejection.

Abstract: PURPOSE:To effectively perform the self-recovery to a failure by use of a case in which recovering work is described. CONSTITUTION:Cases CS1-CS5 are hierarchically classified according to failure symptoms, failures, and classes A-C, and a case suitable to a caused failure is selected to perform recovering work. When the failure can not be recovered by the case application, the work is inferred by qualitative inference to recover the failure. When it is successful, the inferred work is registered as the case of a new class.

Abstract: A computer method and storage structure for storing and accessing multidimensional data is provided. A tree manager provided by the present invention stores data such as pointers, variable length data records, other B-trees, and directories, in a Multidimensional B-tree (MDB-tree). An MDB-tree has an imbedded "parent-child" structure which allows subtrees to be stored within nodes. The subtrees contain subnodes, which, in turn, may contain subtrees. The nodes are indexed by a primary key value while the subnodes in a subtree are indexed by secondary key values. Nodes of a MDB-tree contain a key value table, a subnode table, and a data area. When the tree manager attempts to store a unit of data on a page and the unit of data is too large for the page, the tree manager attempts to split a node currently stored on the page (or the unit of data being inserted) into a subnode and a subtree. The subtree is then stored on a new page. If the unit of data cannot be split into a subnode and a subtree, then one or more of the node currently stored on the page are moved to a new page. <IMAGE>

Abstract: A method for the preparation of polydicarboxysaccharides is provided wherein polysaccharides, such as starch and starch derivatives, are oxidised in the presence of hypobromite and/or hypoiodite and a low oxidising agent concentration is maintained during the oxidation reaction. The low concentration of oxidising agent can be maintained by adding the oxidising agent during the oxidation reaction. The hypobromite or hypoiodite is preferably formed in the reaction medium by oxidation of a catalytic amount of bromide or iodide, either by addition of hypochlorite or by passing an electric current. The product obtained by the method has good calcium and magnesium binding properties and is biodegradable, and thus it is very suitable for use as a builder in detergent compositions.

Abstract: Disclosed are expressible reverse gene constructs, and oligonucleotides, which are characterized by the ability to hybridize with an Ii mRNA molecule, thereby inhibiting translation of the Ii mRNA molecule. These compositions are referred to generally as inhibitors of Ii expression. Also disclosed are MHC class II-positive antigen presenting cells containing an inhibitor of Ii expression. A particularly important class of MHC class II-positive antigen presenting cells are malignant MHC class II-positive antigen presenting cells (e.g., leukemia, lymphoma and melanoma). Also disclosed are methods which results in the display of an autodeterminant peptide, in association with an MHC class II protein, on the surface of an MHC class II-positive antigen presenting cell. In such methods, a specific inhibitor of Ii synthesis is introduced into an MHC class II-positive antigen presenting cell. The specific inhibitor functions, directly or indirectly, through the formation of a duplex molecule with mRNA encoding Ii. The formation of the duplex molecule functions to inhibit Ii synthesis at the translational level. Also disclosed are therapeutic methods for the treatment of malignancy in an MHC class II-positive antigen presenting cell, and autodeterminant peptides which are isolated from an MHC class II-positive antigen presenting cell.

Abstract: A pressure vessel (A) is defined by end walls (16) and side walls (18). In the interior, a plurality of fins (12) define an assembly of thin passages (10) that are filled with a material (26) that expands as it changes from a solid to a fluid state. The passages are thin, on the order of 0.01 inches such that heat is transferred relatively quickly into and out of the material. The passages communicate with a manifold area (14) to a piston bore (40) or other structure (B) for converting fluid pressure into mechanical movement. The piston bore holds a low durometer seal (44), a higher durometer seal (46), and a movable piston (42). To generate rotary motion, the piston and vessel assembly are mounted for rotation about an eccentrically placed member (68). As the pressure vessel goes through heating and cooling reservoirs, the pistons expand and contract causing rotation (FIGS. 4-6). In another application, at least two of the assemblies are interconnected by a heat pump (74) such that heat can be moved back and forth between the two. Additional heat pumps are provided for moving heat from the ambient air or other sources of heat to the pressure vessels (FIG. 7). The actuator is also used to control a two position valve (FIG. 9) and a three position valve (FIG. 10). A pair of actuator vessels (160, 162) are connected by a common heat transfer device (164) for causing differential movement between pistons (166, 168), (FIG. 12).
