Abstract: A mixing connector includes an intake passage, an EGR passage that fetches a portion of exhaust gas exhausted from an engine body to use as EGR gas, and that returns the EGR gas to the intake passage, and a merging section that connects the EGR passage to the intake passage so that longitudinal directions of the intake passage and the EGR passage intersect each other. An upstream side region located on an inlet port side of the intake passage from the merging section on an opposite wall surface configuring an inner surface of the intake passage and located on a side opposite to the merging section includes a first wall surface and a second wall surface which are sequentially arranged at an interval from the merging section side toward the inlet port, and a third wall surface projecting inward of the first wall surface between the first and second wall surfaces.

The ends of the proximal end-side marker are disposed astride at least one of a distal end coupling position and a proximal end coupling position of the first coupling part.

Abstract: Disclosed herein is a catheter comprising an outer shaft; and an inner shaft that is disposed inside the outer shaft, wherein the inner shaft includes: a first shaft part that is made of a first resin, a second shaft part that is made of a second resin, harder than the first resin, and provided on a proximal end of the first shaft part, and a large diameter portion that is provided between the first shaft part and the second shaft part so that a proximal end portion of the first shaft part and a distal end portion of the second shaft part overlap and has an outer diameter larger than an outer diameter of the first shaft part and an outer diameter of the second shaft part, and the large diameter portion includes a joint part joining the outer shaft and the inner shaft to each other.

Abstract: A balloon catheter has a balloon and an outer shaft fixed to a proximal end of the balloon. Each of the proximal end of the balloon and a distal end of the outer shaft has an inner projection extending in an axial direction of the balloon catheter, an outer projection extending in the axial direction, and a gap formed between the inner projection and the outer projection. At a fixing part, the inner projection of the balloon or the outer projection of the balloon is disposed in the gap of the outer shaft, and the inner projection of the outer shaft or the outer projection of the outer shaft is disposed in the gap of the balloon. The balloon catheter has improved fixing strength between the balloon and the outer shaft without increasing an outer diameter of the fixing part between the balloon and the outer shaft.

Abstract: An exhaust recirculation valve includes: a valve housing including an exhaust gas path; a valve element provided to the exhaust gas path and configured to open and close the exhaust gas path; and a stem connected to the valve element and movable in an axial direction, in which the valve housing includes: an inlet from which fluid is supplied from the outside; a recess configured to flow the fluid flowed from the inlet toward the stem; and a throttle in a form of an opening extending from the inlet and oriented toward the stem.

Abstract: To provide an electromagnetic clutch that prevents an armature from being reattracted to a rotor after a bridge wire is cut. Provided is an electromagnetic clutch 10 provided with a power interruption device 50 that forcibly interrupts power transmission to an electromagnetic coil 42. The power interruption device 50 includes a thermally-actuated member 51 attached to a rotor 21 and displaced at over a predetermined temperature, and a bridge wire 52 extending as a part of ground wire of the electromagnetic coil 42 and stretched across an area where the thermally-actuated member moves along with rotation of the rotor 21. The thermally-actuated member 51 is displaced to collide with and cut the bridge wire. The bridge wire 52 has a cutting region apart from a position where the displaced thermally-actuated member 51 collides with the bridge wire 52.

Abstract: Electromagnetic clutch having an electromagnetic coil 42 that causes magnetic attraction between a rotor and an armature is wound around bobbin 41. The bobbin includes: an inner wall 41d and an outer wall 41d, which extend opposite toward a bimetal; and an inner abutment portion 41g and an outer abutment portion 41f, which extend from each extension end of the inner wall 41d and the outer wall 41e toward inner and outer opening edges of a ring case 43 for accommodating the bobbin 41. The inner abutment portion 41f and the outer abutment portion 41g abut the inner and outer opening edges of the ring case 43, by which the bobbin 41 is positioned and accommodated in the ring case 43. In addition, a bridge wire 52 is stretched at the same height on the inner wall 41d and the outer wall 41e.

Abstract: In a sample injector for a gas chromatograph, the present invention improves the throughput of a GC analysis including the derivation of a target compound and reduces the tedious work of handling a reagent for the derivation. According to the present invention, a derivation reagent R is suctioned into a microsyringe 10, after which a small amount of air and a sample P to be analyzed are successively suctioned so that the reagent, the air and the sample are held in this order, from top to bottom. Then, the needle 11 of the microsyringe 10 is inserted through the septum 3 into the sample-vaporizing chamber 2, and the plunger 12 is pushed halfway through so that only the sample is injected into the sample-vaporizing chamber 2. The sample thus injected is quickly vaporized into a gas sample and introduced into the column 6, where the target compound contained in the gas sample adheres to the inner wall of an inlet section of the column 6.
