A configuration detection device includes a light-providing optical fiber, a light reflector a curvature-detecting optical fiber, and a light modulator. The light-providing optical fiber transmits detection light in a plurality of wavelength ranges that have different wavelengths from one another, The light reflector reflects the detection light as reflected light. The curvature-detecting optical fiber transmits the reflected light, and is bent together with an endoscope. The light modulator modulates at least one of the strength or the wavelength of the reflected light for each of the wavelength ranges. Based on at least one of the strength or the wavelength of the reflected light that is pre-modulated and post-modulated, and based on the distance between the light modulator and the output end of the curvature-detecting optical fiber, the configuration of the endoscope is detectable.

An endoscope objective lens with a three-group, three lens element construction, is formed of, in order from the object side, a first lens element having either a negative meniscus shape or a plano-concave shape with its concave surface on the image side, a stop, a positive second lens element having a plano-convex shape with its convex surface on the image side, and a positive third lens element having a plano-convex shape with its convex surface on the object side. The stop is positioned on or in contact with the object-side surface of the second lens element so that the endoscope objective lens is substantially telecentric. Specified conditions are satisfied in order to reduce aberrations and make the manufacture of the endoscope objective lens easier and less expensive.

An imaging apparatus for an electronic endoscope includes a bare chip of CCD, a circuit board with approximately the same thickness as the bare chip, and a conducting plate with no less than 1 / 4 width of the bare chip. The bare chip has terminals on the surface with an imaging surface. The terminals are arranged near the edge facing the rear end of an insertion section of the electronic endoscope. The circuit board has terminals on the surface near the edge facing the front end of the insertion section. These terminals are connected by wire bonding. The conducting plate is attached along one side of the rear surface of the CCD and the circuit board for electrical connection. A forceps channel is provided such that its outer circumference fits partially into a cut portion formed on the rear surfaces of the CCD and the circuit board by the conducting plate.

The electrical apparatus suspension unit 1 is provided with two power supply wires 20-1 and 20-2 by which the electrical apparatus 3 is conducted and suspended from the ceiling 5. Each of the wires 20 is connected to the hung member of the electrical apparatus 3 at the lower end by the a lower holder 40, and connected to the rail 9 laid on the ceiling 5 at the upper end by an upper holder 100. The power supply wire 20 comprises a core wire 21, an insulating layer 23 covering the core wire 21 and an outer layer 25 covering the insulating layer 23. The core wire 21 of the power supply wire 20-1 conducts to a grounded conductor cable W1 and the core wire 21 of another power supply wire 20-2 conducts to a voltage applied conductor cable W2.

There is provided an optical modeling apparatus that forms a model of a desired shape by sequentially forming hardened layers by irradiating a light curable resin with light. The apparatus includes a first light source that emits a light beam for plotting on the resin, a scanning device that scans the light beam from the first light source over the resin, a second light source that emits light that irradiates one fixed region of the resin at a time, a spatial light modulator that spatially modulates the light from the second light source and blanket-exposes a specified region of the resin, and an exposure position adjuster that moves, in at least one direction, the light from the spatial light modulator. The light beam from the scanning device and the light from the spatial light modulator form each hardened layer.

The invention relates to a fitting for connecting lengths of pipe by compression, having a substantially cylindrical internal contour. The fitting has a ridge which is configured in a radially outward direction and in which a sealing element is provided. The fitting is slidable onto the lengths of pipe, the internal contour having a region of non-circular cross-section. The invention also relates to a connecting arrangement for connecting lengths of pipe by compression, comprising a length of pipe and a fitting plus a sealing element which is arranged in the ridge. One axial gap which extends over the entire connecting region is formed between the length of pipe and the internal contour of the fitting in the uncompressed state. Such an axial gap with an open end would ensure that a leak exists even in the region of the sealing element in an uncompressed state.

A waterproof method for a wire end joint includes expanding a heat shrinkable tube radially outwardly. The method then includes inserting the wire end joint and a melted thermosetting waterproofing agent through an opening at an end of the waterproof protection tube. A solidification starting temperature of the waterproofing agent is set higher than a shrinkage starting temperature of the heat shrinkable tube. The method then applies heating so that the heat shrinkable tube shrinks to the original diameter and so that the waterproofing agent is not solidified. The heating is continued to the solidification starting temperature after the heat shrinkable tube is shrunk to a set inner diameter, thereby causing the thermosetting waterproofing agent to be solidified.
