The present invention provides a conductive pattern that has low electric resistivity, is superior in adhesion to a substrate and does not cause substrate cracking during plating, a multilayered substrate incorporating such a conductive pattern, and a fabricating method for a multilayered substrate. At first, a conductive composition including a metal powder containing not less than 95 mass % of Ag, a sintering restrainer containing Cr and/or Cr compound, a dielectric loss conditioner containing Mn and/or Mn compound, and a vehicle is prepared. Next, electrodes made of the conductive composition are formed on a plurality of green sheets. The plurality of green sheets formed with the electrodes are then laminated to form a laminated product, whereafter the laminated product is sintered.

A ceramic capacitor having an extremely thin plate (as little as 10 .mu.m) with a pair of electrodes on both the surfaces of the plate, said thin plate is supported by the thick dielectric plate which is laminated with said thin plate. The thick plate has a through hole, in the vertical direction of the same, and said through hole is filled with a through hole conductor which connects electrically the external terminal on the outer surface of the thick plate and the inner electrode on the thin plate. The material of the thick plate is the same as that of the thin plate, and a pair of lead lines are soldered to the external terminal and the outer electrode on the thin plate.

A packaging container includes an outer container, a packaging bag, and an inner packing member. The outer container has a box-like shape and has a containing space and a passage opening. The packaging bag is contained in the outer container in a state in which the packaging bag contains an object. The packaging bag includes a containing portion, an opening portion formed in the containing portion and allowing the object to pass therethrough, and a handle portion graspable by a user. The inner packing member is disposed between the object and the passage opening and contained in the containing space. At least part of the handle portion is disposed on the passage opening side of the inner packing member, and the handle portion moves toward the passage opening together with the inner packing member when the inner packing member is being removed from the outer container.

摘要:
Disclosed is an image transferring apparatus for transferring an image displayed by a first program to a second program. The image transferring apparatus comprises: image copying means for storing a copy of the image into a predetermined temporary storage area; and image transferring means for acquiring the copy of the image from the temporary storage area before transferring the acquired copy to the second program. With this configuration, the image displayed by a first program is transferred to a second program by way of a temporary storage area, in accordance with display position information about the on-screen image, or in the form of a file accommodating the image of interest. The transfer of the image between the programs is accomplished in a simplified and reliable manner.

A packaging container includes an outer container having a containing space and a passage opening, and a packaging bag for containing an object. The packaging bag includes a containing portion, an opening portion, and a handle portion. The handle portion includes strip-like members each connected to the containing portion at two connection portions. The handle portion has a length equal to or larger than half a length of the object along the passage opening when the handle portion is extended in a direction along the passage opening. When the handle portion is extended in a direction through the passage opening, the handle portion has a length with which the handle portion is allowed to protrude away from a surface of the object adjacent to the passage opening toward the passage opening and the connection portions are located at positions separated away from the surface toward the passage opening.

An illumination system for endoscopes has a light guide bundle constructed and arranged to illuminate an object to be observed. The light guide bundle is extended in an axial direction of the endoscope and branched into a plurality of branch portions in a frame which is adapted to be disposed inside of the endoscope. Each of the branch portions have a crescent-shaped cross-section at a mid-portion along the axial direction of the endoscope and each of the branch portions have at least one bent portion in which a protective glass plate is disposed on each exit surface of the branch portions. An endoscope system includes the above illumination system.
