Thus, a new tool whereby immunity can be appropriately induced in vivo is provided.

Abstract: An exhaust pipe structure for an in-line four-cylinder internal combustion engine includes: an in-line four-cylinder internal combustion engine; four exhaust pipes connected with respective exhaust ports in respective cylinders of the internal combustion engine; and a converging exhaust pipe connected with a converging portion at which downstream ends of all the exhaust pipes converge. In this exhaust pipe structure, the exhaust pipes are each configured as a dual pipe including an outer pipe and an inner pipe disposed inside the outer pipe. At the converging portion, the four exhaust pipes are arrayed linearly in parallel with each other, and the outer pipes of adjacent ones of the exhaust pipes are directly welded with each other at the downstream ends.

Abstract: An air cleaner is arranged below a fuel tank of a straddle type disposed above left and right main frames. The air cleaner includes a main chamber which is located between the main frames, and a sub-chamber which is located on the outside in the vehicle width direction of the main frames. A rear section of the sub-chamber and a rear section of the element within the sub-chamber are located in a space formed between each outside wall surface of the main frames and an inside wall surface of the fuel tank. A front section of the sub-chamber and a front section of the element project forwardly of the fuel tank in a side view of the vehicle. The front section of the sub-chamber is provided with the fastening means for fastening the side cover (the element lid) which covers the element from the outside in the vehicle width direction.

Abstract: A drying apparatus for manufacturing a pressure-sensitive adhesive tape in which a pressure-sensitive adhesive layer is formed on a strip-shaped long tape base material is provided. The drying apparatus dries coating agent coated at least on one surface of the tape base material. The tape base material that is transferred in a lengthwise direction thereof is spirally wound around a cylinder body from one end side of the cylinder body to the other end side of the cylinder body in a slidable state. The cylinder body is formed with a plurality of air holes on an entire circumferential wall thereof, around which the tape base material is spirally wound, the air holes through which warm air or hot air flows from the inside of the cylinder body to the outside of the cylinder body.

Abstract: A switch having a molded article of which the entirety or a part is composed of an organic and inorganic complex composition is provided, wherein the base inside of the base of a box is composed of for example an organic and inorganic complex composition with the resin content at 15 to 70 wt % and the content of one or more inorganic compounds capable of dehydration at 150° C. or more at 80 to 30 wt %.

Abstract: A welding fuel tank has a magnet 3 disposed on the inside or outside thereof in the vicinity of a fuel pump 12 which is housed inside the fuel tank. The magnet collects magnetic spatter which remains inside the fuel tank after welding and prevents the spatter from entering the fuel pump. The magnet may be a permanent magnet or an electromagnet, and it may be disposed outside the pump or in the fuel filter of the fuel pump. A cleaning method for a welded fuel tank comprises introducing a magnet into a fuel tank after welding, vibrating the fuel tank so that the magnet will move about the inside of the fuel tank and collect magnetic spatter, and then removing the magnet and spatter from the fuel tank.
