Abstract: A clip attaching structure includes a clip supporting portion which protrudes on an outer circumferential surface of a main body, a clip, and a coil spring. The clip is configured to be rotatable with respect to a fulcrum at which the clip is engaged with the clip supporting portion. The convex portion is inserted into an inside of one end portion of the coil spring, and the other end portion of the coil spring abuts against the outer circumferential surface of the main body. A base portion of the convex portion has an outer diameter greater than an inner diameter of the coil spring, and a tip end portion of the convex portion has an outer diameter smaller than the inner diameter of the coil spring.

Abstract: A clip attaching structure includes a clip supporting portion which is protruded on an outer circumferential surface of a main body, a clip, and a coil spring. The clip is configured to be rotatable with respect to a fulcrum at which the clip is engaged with the clip supporting portion. The coil spring is provided being closer to one end portion of the clip than the fulcrum, and biases the other end portion of the clip to make the other end portion abut against the outer circumferential surface. The clip has a convex portion which is protruded towards the outer circumferential surface of the main body. The convex portion is inserted into an inside of one end portion of the coil spring. The other end portion of the coil spring abuts against the outer circumferential surface of the main body.

Abstract: A method for producing an unsaturated dimer by reacting an ?-olefin having 6 to 14 carbon atoms in an agitated vessel, wherein a metallocene-based catalyst is used as a reaction catalyst; and the supply flow rate of hydrogen (VH) to the vessel is 0.2 to 1.2 [(NL/hr) per L of olefin] and the agitation power (Pv) is 0.18 KW/m3 or more of the time of reaction.

Abstract: Solid biomass having a moisture content in a range of 30 to 95 mass % is brought into contact with ammonia gas at a pressure in a range of 0.5 to 4 MPa and held at 50 to 200 degrees C. Subsequently, the solid biomass is rapidly decompressed to be blasted. The ammonia gas evaporated by decompression is recovered and recycled. The ammonia gas can be brought into contact with the entire solid biomass evenly and in a short time. Since absorption heat of the ammonia gas is generated, energy consumption required for additional heating can be reduced.

Abstract: The apparatus of the present invention detects the resonant frequency of a vibratory member in contact with the fluid in order to determine the density or pressure of the fluid. The vibratory member is disposed in a housing to form a cavity with no flow communication between the side of the vibratory member facing into the cavity and the other side of the vibratory member. The vibratory member is vibrated by an annular piezoelectric device which may be attached to one or both sides of the vibratory member. An amplifier and feedback circuit regulate the frequency of oscillation of the piezoelectric device to that of the resonant frequency. The piezoelectric device may be comprised of several separate sections or several sections with partial interruptions in the piezoelectric material. Instead of the vibratory member and the piezoelectric transducer combination, the vibratory member may be constructed from a single fixed piezoelectric device with another piezoelectric disc mounted thereon.

Abstract: A Karman vortex flow meter including an upstream columnar body having a substantially isosceles triangular cross section and a downstream columnar body having a substantially isosceles trapezoidal cross section. The downstream columnar body has a base surface which is substantially equal in width to the base surface of the upstream columnar body. The two bodies are positioned in a stream of a fluid with their base surfaces disposed at a distance from each other in mutually parallel relation and at right angles to the stream for generating Karman vortices to measure the flowing speed or rate of the fluid based on the frequency of the vortices. The upstream columnar body has a pair of rounded edges along its base surface.

Abstract: Disclosed is an inspection endoscope for medical or industrial applications, by which an observer can know the degree of the color change, inner pressure and temperature while the observer inspects, for example, the interior of the colon. In the eye lens zone of this inspection endoscope, not only the image of the inspection object fed from an image guide but also other factors such as the color, inner pressure and temperature are simultaneously displayed, and therefore, the inspection can be accomplished objectively while the inspection object is observed.
