摘要： PROBLEM TO BE SOLVED: To suppress the deformation of an inside duct 4 the factors of which are the change of pressure in a hollow part (air intake passage 22) etc. SOLUTION: A duct producing method includes a blow molding process in which a parison formed by extruding a heated/molten synthetic resin in the shape of a tube is blow-molded to form a blow-molded body 46 with a hollow part 47 formed inside, and simultaneously a plurality of hollow projections 54 and 55 protruding outside from the outer surface of the blow-molded body 46 are formed and a mold clamping process in which a blow molding mold 9 is clamped to crush the hollow projections 54 and 55 pinched between a plurality of slide cores 71 and 72 and between a plurality of the slide cores 72, and a plurality of reinforcement ribs 60, 61, 63-67 thicker than the film thickness of thin film parts 41-45 are formed on the outer surface of the blow-molded body 49. In this way, the inside duct 4 which is resistant to deformation although the film thickness of the thin film parts 41-45 is very thin can be produced inexpensively. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce noise from an intake passage 2, in either the case of low-frequency noise or high-frequency noise in a muffler 1.
SOLUTION: This muffling device 1 has a double-pipe structure, provided with an inner pipe 3 forming a part of the intake passage 2, and an outer pipe 5 disposed at an outer circumference side of the inner pipe 3 and forming a volume chamber 4 at a part between the inner pipe 3 and the same. The muffling device 1 is provided with a reed valve 15 for opening and closing a communication hole 12 that provides communication between the volume chamber 4 and the outside of the outer pipe 5. The reed valve 15 opens the communication hole 12, when sound wave propagated in the intake passage 2 is high frequency noise, and closes the volume chamber 4, by closing the communication hole 12 when it is low frequency noise. Consequently, since the volume chamber 4 is closed in case of low frequency noise, resonator effect is shown by resonance of a thin film 10 to the low-frequency noise, intake noise and penetrating noise can be reduced. For the case of high-frequency noise, intake noise is reduced, by making the sound waves propagated in the intake passage 2 penetrate the thin film 10, and penetrating noise can be shielded by the outer pipe 5.

摘要： PROBLEM TO BE SOLVED: To reinforce a thin film 4 at low cost, in a sound attenuation duct 1 which reduces the intake noise by the vibration of the thin film 4.
SOLUTION: In the sound attenuation duct 1, the thin film 4 is supported by a cylindrical column 3 from the inside. The thin film 4 is supported by the simple-structure column 3 from the inside and deformation of the film can be prevented. Consequently, the thin film 4 can be reinforced at low cost. Since a bar-shape body 8, preventing inclination of the column 3, passes through the column 3, the column 3 can stably support the thin film 4 without its inclining.

摘要： PROBLEM TO BE SOLVED: To reduce noise from an intake passage 2, in both of either the case of low-frequency noise and high-frequency noise in a muffler 1.
SOLUTION: The muffler 1 has a double pipe structure, provided with an inner pipe 3 forming a part of an intake passage 2, and an outer pipe 5, disposed at an outer circumference side of the inner pipe 3 and forming a space 4 with the inner pipe 3. A communication hole 12, providing communication between the space 4 and an outside of the outer pipe 5, is provided at a pipe wall 11 of the outer pipe 5, and a Helmholtz-type resonator 15, of which the resonance frequency is set in low frequency region is connected to the outer pipe 5. As a result, when high-frequency noise propagates in the intake passage 2, intake noise is made to penetrate a thin film 10 and is thereby reduced, and the penetrating noise is insulated by the outer pipe 5, to reduce the noise from the intake passage 2 in the case of high-frequency noise. When low-frequency noise propagates in the intake passage 2, penetrating noise can be reduced by the Helmholtz-type resonator 15, connected to the outer pipe 5, that reduces the noise from the intake passage 2, in the case of low-frequency noise.

摘要： PROBLEM TO BE SOLVED: To enhance the mountability of a tone quality controller in the engine room of an automobile. SOLUTION: A thin film partition wall 7 which divides airtight a communication passage 14 from a resonance chamber 19 and vibrating by resonating with the specific frequency of an intake noise propagated in the intake duct is adopted as the inner tube of the double tube part 3 of the intake duct 2 of the engine. Since the intake noise with a desired frequency can be taken out from the intake duct 2 into the cabin of the automobile by tuning the shape, film thickness, surface, or position of the thin-film partition wall, the tone quality in the cabin of the automobile can be improved. Since the tuning of the taken-out tube can be easily performed without relying on the duct length of the branch duct 4, an increase in the size of the resonance chamber 19 at the double tube part 3 of the intake duct 2 can be suppressed. Consequently, the mountability of the resonance chamber 19 of the double tube part 3 in the engine room of the automobile can be enhanced by reducing a mounting space in the engine room of the automobile.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a thin and high strength inner duct the cross sectional area of which are of approximately the same at the body and the end or greater with the body.
SOLUTION: The inner duct is produced from a thermoplastic resin such as PET or PEN by stretch blow molding. More specifically, the manufacturing method comprises molding the resin into a cylindrical preform 20 in which the larger diameter parts 20a at the ends are narrowed down to the middle part 20b in the cross sectional area, heating the preform 20 and blowing high pressure gas into the inside of the preform 20. In the stretch blow process, the cross sectional area of the middle part 20b narrowed in the molded preform 20 is stretch blow-molded in the radial direction until it becomes approximately the same as that of the larger diameter parts 20a. The manufacturing method can be suitably used for producing an inner duct with a thin wall and yet a high strength. Since the resultant molding does not have a bottom, no additional step to cut off the bottom is required and no waste is produced.
