Patent CA-2157073-A1 (CA)
Title: Light-transmitting outer casings for endoscopes and methods of making
Inventor: CAWOOD CHARLES DAVID
IPC: G02B23/24
Filed: 1995-08-28
Abstract: An endoscope which provides ample illumination to a surgical field or diagnostic site is disclosed in which a lens train having objective and relay lenses or electronic means for transmitting images therethrough is covered by an outer casing formed from a woven cylindrical sheath composed of a multiplicity of interlaced spirally-extending bundles of optical fibers and an embedding medium for securely interlocking the bundles together.  The proximal end of the braided or woven sheath forms a light-receiving post for receiving and transmitting light through the individual fiberoptic cables to their distal ends which terminate around the periphery of the field lens or lenses.  Constructing the outer casing of the endoscope from woven fiberoptic bundles provides an adequate quantity of fiberoptic cables to supply ample illumination to the field for endoscopes with one or more field lenses.  The construction of the braided sheath also allows the endoscope to be efficiently manufactured.  In one alternate embodiment, the outer casing is formed from a plurality of woven radial segments each composed of a multiplicity of interlaced spirally-extending bundles of optical fibers and an embedding medium securely interlocks the radial segments together to form the tubular outer casing.  In another alternate embodiment, the outer casing is formed entirely of light-transmitting material and may take the form of interwoven fiberoptic cables which are fused together or an integral, elongate tubular sheath which fits over the lenses or electronic means of the lens train.

Patent CA-2161760-A1 (CA)
Title: Focus controller of camera
Inventor: NISHIYAMA KIYOHARU
IPC: G02B7/36
Filed: 1995-10-30
Abstract: In a focal controller of a camera, two brightness components in different frequency bands are obtained by two band pass filters from a video signal obtained by image pickup.  Integral values a and b of the respective brightness components are detected by integrating circuits.  When both a ratio a/b and a value a calculated by an arithmetic circuit are increased, a CPU judges this increase as an unfocusing position of a focusing lens.  In contrast to this, when an increasing degree of the ratio a/b is decreased or tends to be decreased, the CPU judges this decrease as a position near a focusing position of the focusing lens.  Thus, the driving speed of a focusing motor is set to a high speed in the unfocusing position and is set to a low speed in the position near the focusing position.  For example, a microcomputer obtains a focal evaluation value at an interval of three fields (k+2 after k-1) in the vicinity of a focusing position and compares this focal evaluation value with reference data.

Title: Apparatus for reducing drag
Inventor: SWITLIK STANLEY
IPC: B62D35/00
Filed: 1996-03-08
Abstract: An improved apparatus for reducing the drag of a moving body at the trailing end thereof by positioning panels extendable rearwardly from the trailing end of the moving body to minimize drag wherein deployment of the rearwardly extending panels is facilitated such as by allowing for automatic deployment of an upper horizontal panel responsive to conventional deployment of one or more vertically extending panels at forming the upper panel in a frame construction covered by flexible material.  The upper panel can be spring loaded to further facilitate deployment and the lower horizontal panel can be easily deployed and possibly stored with respect to one of the vertically extending panels.  Use of the frame configuration for deploying the upper horizontal panel also facilitates movement from the deployed to the stored position such as by including release cords preferably secured at one end with respect to the vertically movable preferably trapezoidally shaped frame.  Two such horizontal panels with separate frames can be utilized to achieve full deployment of a horizontal panel across the lateral dimension of the trailing end of such a moving vehicle.          Several novel configurations for deployment of a lower horizontal panel are also included herein.  Also two similar horizontal foldable sections can be used to form the lowermost horizontal panel to form a completely automatic deployable device.

Title: Incremental compilation of c++ programs
Inventor: NACKMAN LEE RICHARD
IPC: G06F9/45
Filed: 1996-05-01
Abstract: An enhanced compiler for compiling C+ + programs without the use of forward declarations normally included in program header files. Through multiple parsingpasses, the compiler extracts definitions for the declarations directly from the bodies of the C+ + files. By saving the definitions to a persistent program representation, for example a program database, on subsequent sweeps, only definitions for new or changed declarations need be updated. In this way, C+ + programs can be incrementally compiled on a declaration by declaration basis.

Title: Sheet for protecting paint films of automobiles
Inventor: MATSUI KOMAHARU
IPC: C09J7/22
Filed: 1996-10-08
Abstract: A sheet for protecting paint films of automobiles for adhering to the incompletely cured paint films of automobiles comprising two pack urethane paint, the sheet comprising a support and a pressure-sensitive adhesive layer formed thereon, wherein the sheet has a Young's modulus E of at least 75 N/mm2 and a coefficient of flexural stress k represented by the formula k = Eh3 wherein h is a thickness of the support, of 0.035 or less.  The protective sheet can uniformly protect the paint films and easily be peeled and removed therefrom without causing environmental problems and adhesive remaining of the pressure-sensitive adhesive layer.   Even when the sheet is adhered to incompletely cured paint films of automobiles and they are allowed to stand for a long period of time under an outside high temperature in summer, the sheet does not cause the deformation of the paint film and the microdeformations by the deformation of the paint film at the edge portion of the pressure-sensitive adhesive layer.  The protective sheet can be reserved in a roll state without causing the change of form by, for example, a telescope phenomenon.

Title: An Electron Jet Vapor Deposition System
Inventor: HALPERN BRET
IPC: H01J37/305
Filed: 1996-02-09
Abstract: A gas jet film deposition system includes a source of thermionically emitted electrons which are accelerated through carrier gas and generate He ions by impact ionization. The resultant electron avalanching and multiplication generates an extremely dense plasma, and produces large electron currents. The electron current is collected at a free, high electric field end of a crucible. The present system can generate vaporized evaporant which is entrained in the gas jet and thereby provide a high density source of ions. The ions may be presented to a substrate together with or without the evaporant.

Title: Porous carbonaceous material, process for producing the same, and use thereof
Inventor: NAKAMURA AKIHIRO
IPC: B01J21/18
Filed: 1996-03-29
Abstract: A porous carbonaceous material that can adsorb large quantities of nitrogen, oxygen, carbon dioxide and methane is produced in a high yield by a process which comprises the step of halogenating carbonized coal by contact with a halogen gas to yield halogenated carbonized coal and the step of dehalogenating the halogenated coal to eliminate part or all of the halogen atoms therefrom.  When this material is used for preparing an electric double-layer capacitor, the obtained capacitor has a larger electrostatic capacity than those prepared from other carbonaceous materials.  Thus it is possible to produce a carbonaceous material having micropores and/or submicropores suitable for adsorbing small molecules of nitrogen or the like and storing electrochemical energies.
