Granted: 1998-08-04
Abstract: In  a  method  for  reinforcing  defective portions  (14)  of a  pipeline  (10),  the  defective portions are identified by conventional techniques, soil is excavated from around the pipeline to expose the deteriorated portions,  any corrosion protection material is removed and the surface of the pipeline is cleaned.   Gouges,  dents  and corrosion pitting are filled with an uncured filler material (12) and, while the filler material is in an uncured workable state, a plurality of convolutions of a high tensile strength material (20) are wrapped around the defective portion of the pipeline with a layer of a curable adhesive (18)  applied  between  adjacent  convolutions.    The adhesive then cures to a strongly adhesive state and the filler material cures to a rigid state capable of transferring  the  fluid  pressure  load  within  the pipeline almost instantaneously to the reinforcement band.   Optionally,  a layer of adhesive  (18) may be applied between the pipeline  surface  (16)  and the first convolution of the reinforcement band, in which case the adhesive must be compatible with the filler material  so that  both materials  are  able to  cure fully,   and  also  compatible  with  any  corrosion protection material remaining on the pipeline.   The method may be employed to reinforce both straight and bent portions of a pipeline.

Title: Output light wavelength control method in optical communication system for transmitting optical signal output from optical transmitter, optical transmitter and optical transmitter/receiver used in the optical communication  system, and optical communication system using the same
Inventor: MAJIMA MASAO
IPC: H04Q11/00
Filed: 1996-03-22
Granted: 1999-08-24
Abstract: In an optical communication system for performing wavelength division multiplex communication on an optical transmission path, an output light wavelength control is performed as follows in an optical transmitter.  A wavelength of light on the optical transmission path is detected so as to search for an unoccupied space, in which output light from the self optical transmitter does not cause an interference with another light on the optical transmission path.  The wavelength of the output light from the self optical transmitter is controlled so as to be a wavelength falling within the unoccupied space.  A wavelength of another light which is adjacent to the wavelength of the output light from the self optical transmitter on one of the longer and shorter wavelength side along a wavelength axis is set as a reference side wavelength, so that the wavelength of the output light is controlled to set a wavelength interval between the reference side wavelength and the wavelength of the output light from the self optical transmitter to be close to a predetermined first wavelength interval or to maintain the wavelength interval to have a value in the neighborhood of the predetermined first wavelength interval.

Abstract: This is an implantable vaso-occlusive device. It is typically a vaso-occlusive coil comprised of a primary helically wound coil which may then be wound into a secondary shape. Central to the invention is the use of a stretch-resisting member fixedly attached within at least a portion of the primary coil.The stretch-resisting member may be formed into coil tips at the ends of the coil by melting the polymeric fibers or alloys or by attaching the fibers with a glue. This stretch-resisting member is for the primary purpose of preventing stretching of the coil during movement of that coil, e.g., by retrieval or repositioning after deployment. The device typically has a self-forming secondary shape made from a pre-formed primary linear helically wound coil, although it need not have the secondary form. External fibers may be attached to the device and affixed to thepre-formed linear member to increase. The vaso-occlusive member may be also be covered with a fibrous braid. The device is typically introduced into the body through a catheter. The device is passed axially through the catheter sheath andassumes its secondary form upon exiting the catheter.

Abstract: An antenna apparatus, a method of manufacturing the same, and a method of designing the same,  are provided.   A first dielectric layer, first dielectric film, second dielectric layer and second dielectric film are laminated on a flat metal plate in the mentioned order.   A radiation element  fed  through  a feeding line is arranged below another radiation element that is not fed through the feeding line.  The feeding line forms, along its overall length, a microstrip line having the dielectric layer sandwiched by the feeding line and the flat conductive plate, resulting  in no model  change  from the microstrip  line to  a triplate line or vice versa, with reduced feeding loss.   The thickness of the dielectric layer is so set as to be sufficiently small compared with the used wavelength, to thereby suppress the radiation  from  discontinuities  lying  on  the  microstrip  line constituted of the feeding line and flat conductive plate.  This eliminates the need for a metal shield plate to prevent unneces-sary radiation from the feeding line.
