  • Patent number: 7389807
    Abstract: When a fitting piece slips out of a rail groove of a guide rail in connection with an excessive load on a shutter curtain is restored to the rail groove, the restoration is reliably set and noiselessly carried out. A posture holding bar and fitting pieces, which are spaced from both right and left sides of the posture holding bar at a predetermined interval, are provided at the lower end portion of the shutter curtain. A first guide body guides the posture holding bar to the opposing site to the rail groove in the process of an opening/closing operation of the shutter curtain. A second guide body guides the fitting piece at the lower end portion of the shutter curtain to the opposing side to the rail groove in conformity with a timing at which the posture holding bar is positionally regulated to the opposing side to the rail groove by the first guide body is provided at the upper side of the rail groove constituting the guide rail.

  • Patent number: 6319197
    Abstract: A medical system having an endoscope probe intubated into a body, a signal processing circuit for processing a signal for the probe and an electric source circuit insulated from a commercial electric source. A part of the signal processing circuit connected to the probe is isolated by an isolation circuit to secure the safety. An impedance element is employed to prevent a malfunction by reducing an emission/permeation of noises. No adverse influence is thereby exerted on outside units.

  • Patent number: 5672251
    Abstract: The method for producing a metallic wiring board of this invention comprises the steps of: implanting nitrogen on a surface of a substrate; forming a metallic film including, as a main component, one of Ta and Nb on the surface of the substrate where nitrogen is implanted by a sputtering method to form a metallic wiring by patterning the metallic film; and forming an insulating film by anodic oxidation of a surface of the metallic wiring. In the step of forming a metallic wiring form Ta or Nb on a substrate or a protective layer including nitrogen to anodic-oxidize the surface of the metallic wiring, Ta ions or Nb ions do not enter the substrate. Further, the substrate or a protective layer is doped with nitrogen, and a Ta layer is formed by the sputtering method thereon. The sputtering method has a characteristic that a material contained in the substrate is mixed into a film formed in the initial stage of the coating. Therefore, the doped nitrogen enters the Ta film, and a thin .alpha.

  • Patent number: 5434363
    Abstract: A metallic wiring board includes nitrogen implanted in a surface of a substrate or a protective layer including nitrogen formed on the substrate upon which is formed a metallic film including, as a main component, one of Ta and Nb. An insulating film covering the metallic wiring is formed by anodic oxidation. The nitrogen in the substrate or the protective layer prevents Ta (or Nb) ions from entering the substrate during the anodic oxidation of the metallic wiring. As a result, insulating properties of the substrate are not degraded during the oxidation.
