摘要： PROBLEM TO BE SOLVED: To reduce a radiation sound radiated from an opening part to permit a penetration component to pass through with a simple constitution.
SOLUTION: The radiation sound reduction device 24 is provided in an inner side of the opening part 22 of a fender apron 18. A second passage 30 is formed in the inner part of the radiation sound reduction device 24, a second inlet port 28A is disposed on an engine room side, and a second outlet port 28B is disposed on the opening part side. When a passage length of a first passage 28 formed at the center of the radiation sound reduction device 24 is L1, the passage length of a second passage 30 is L2, and the half wavelength of the frequency of the radiation sound for reducing which is transmitted from the opening part 22 to the outside part is λ/2, λ/2=L2-L1 is satisfied. Since the radiation sound radiated from a second outlet port 30B is shifted by the half wavelength λ/2 with respect to the radiation sound radiated from the first outlet port 28B of the first passage 28, the radiation sound radiated from the first passage 28 is canceled, and an engine sound radiated to the outside is sufficiently reduced even if a comparatively large opening part 22 for permitting a tie rod to pass through is formed.

摘要翻译：要解决的问题：为了减少从开口部分辐射的辐射声，以允许穿透部件以简单的构造通过。解决方案：辐射消音装置24设置在翼子板围裙18的开口部分22的内侧。第二通道30形成在辐射减声装置24的内部，第二入口 28A设置在发动机室侧，第二出口28B设置在开口部侧。当形成在辐射消音装置24的中心的第一通道28的通道长度为L1时，第二通道30的通道长度为L2，并且传输的减少辐射声的频率的半波长从开口部22向外侧部分为λ/ 2，λ/ 2 = L2-L1。由于从第二出口30B辐射的辐射声相对于从第一通道28的第一出口28B辐射的辐射声移动半波长λ/ 2，所以从第一通道28辐射的辐射声被取消并且即使形成用于允许拉杆穿过的较大的开口部22，辐射到外部的发动机声也充分降低。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a temperature sensitive type fan coupling device which enables temperature control with higher accuracy based upon the atmospheric temperature. SOLUTION: The introducing amount of viscous fluid introduced between a rotor 52 and a housing 54 to transmit driving force from the rotor 52 to the housing 54 is adjusted by rotational displacement of a rotating valve 61. While a bimetal 62 sensing the atmospheric temperature is provided outside a housing 54, a bimetal 21 sensing the temperature in the housing is provided inside it. The bimetal 62 is deformed by sensing the atmospheric temperature so that the bimetal 21 is rotationally displaced. While receiving rotational displacement from the bimetal 62, the bimetal 21 itself is deformed by sensing the inside temperature of the housing 54 so as to rotationally displace the rotating valve 61 by taking the displacement into account as the displacement in the direction opposite to the rotational displacement from the bimetal 62. By so doing, the influence exerted by temperature rise of the housing 54 is compensated.

摘要： PROBLEM TO BE SOLVED: To provide a shielding plate and a mounting structure for a shielding plate with good attachment/detachment property while sufficient noise reduction performance.
SOLUTION: Since in the shielding member 10A, opening parts 24A-24C are constitute by constitution members 26A-26D dividable in a vertical direction, i.e., an attachment/detachment direction, attachment/detachment is also easy at a side in a vehicle width direction of an engine with piping and wiring. Since the opening parts 24A-24C are the minimum opening area corresponding to piping and wiring, leakage of engine noise from a clearance of the piping and the wiring of the opening parts 24A-24C is suppressed to minimum and the shielding plate 10A can ensure the sufficient noise reduction performance.

摘要： PROBLEM TO BE SOLVED: To provide a duct for intercooler cooling capable of enhancing suppression effect of engine noise radiated to the outside of an engine room even when the duct for intercooler cooling is attached regardless of space restriction of the engine room.
SOLUTION: A wall part 22B on the engine room 14 side of the duct 10 for intercooler cooling for introducing air to the intercooler 16 arranged on an engine hood 18 and arranged just above the engine from the outside of the engine room 14 is constituted by a sound-absorbing material. Thereby, regardless of space restriction of the engine room 14, the effect for absorbing the engine noise can be enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a reverberation-type measuring device for sound absorption effectiveness in which a reverberation room with nonparallel walls is effectively used to secure miniaturization and satisfactory measurement performance. SOLUTION: A reverberation room 10 is a compact reverberation box formed of a plurality of non-parallel walls. A leakage hole part 13f is formed on the lower part of a wall part 13a among a plurality of the walls of the reverberation room 10. A speaker 20 is arranged on a wall part 13d and generates sound in the reverberation room 10 at the time of receiving random noise which is outputted from a random noise generator 30 through an amplifier 40. When a microphone 50 detects levels of leakage sound pressure from the leakage hole part 13f, the sound absorption performance of a sound absorbing material S is measured on the basis of the detected levels of leakage sound pressure.
