Title: Sound insulating material
Inventor: YAMASHITA MIKIO
IPC: E04B1/86
Filed: 1994-12-22
Abstract: PURPOSE: To provide a sound insulating material which is excellent in low frequency sound insulating performance and is also excellent in high frequency sound insulating performance. CONSTITUTION: A sound insulating material 1 has a structure that a high density pad material 3, a film 4, a low density pad material 5 and the skin 6 having comparatively large mass are layered in order, and the high density pad material 3 is arranged in a condition of contacting with a wall body 2. A noise and vibration are transmitted to the wall body 2. The high density pad material 3 contacting with the wall body 2 restrains vibration of the wall body 2, and restrains vibration (a low frequency noise) transmitted to the wall body 2. A low frequency noise incident on the sound insulating material 1 is attenuated by vibrating the skin 6 supported with the low density pad material 5.  On the other hand, a high frequency noise incident on the sound insulating material 1 is absorbed by the high density pad material 3, and the high frequency noise passing through the high density pad material 3 is reflected by the film 4, and is again absorbed by the high density pad material 3. That is, the high frequency noise is reflected between the wall body 2 and the film 4, and is absorbed in the high density pad material 3 with high efficiency.

Abstract: PURPOSE:To enable reduction of the size and the weight of an internal combustion engine, by a method wherein a crank having no balance weight is used for crank arm, and an eccentric weight is situated to the rotary body of the extension part of a crank shaft outside a crank chamber. CONSTITUTION:A fly wheel 15 and a disc 17 are secured to the extension parts on both sides of a crank shaft 5, an eccentric weight 18 is secured to the fly wheel 15, a hole 19 is formed in the disc 17, and an eccentric weight 20 is mounted to an opposite part. Therefore, there is no need to mount a balance weight formed integrally with a crank arm 5a, and a relatively large gap is formed in the lowering position of a piston 3 and between the upper surface of the crank arm 5a and the under surface of the piston 3. Thus, through decrease of the length of a piston rod 4, the gap is decreased, and the height of an engine can be decreased. Further, since no balance weight is provided, through decrease of the thickness in an axial direction of the crank arm 5a, a distance between bearings can be reduced. This constitution enables reduction of the size and the weight of the engine.
