IPC: E04F17/10
Filed: 1990-08-31
Abstract: PURPOSE:To reduce noise generation sources, simplify the structure, and reduce the facility cost by providing multiple running blocks with dust mounting buckets each having a reaction plate with an electromagnetically excited linear motor along an endless circulating rail suspended in a shaft. CONSTITUTION:When wastes and dust bags are mounted on a bucket 2 on the right side, the bucket 2 starts to be lowered by its weight. When the descent starts, a reverse-phase electric signal is output to a linear motor 10 from a control device to cause the reverse thrust, and a braking force is applied to the bucket 2. The bucket 2 is lowered at a nearly constant speed without being set to the free fall state, When it reaches the lower end of an endless circulating rail 1, a running block 3 is turned along the rail 1 toward the ascent side of the rail 1, thus the bucket 2 is turned downward, and the mounted wastes are dropped to a dust storage section at the lower section of a shaft 11. When the bucket 2 is separated from the lower end of the linear motor 10 and lowered, the reverse-phase electric signal output to the linear motor 10 is turned off.

Filed: 1988-09-14
Abstract: PURPOSE:To attain the setting of a different high frequency limit frequency optionally without using a different diaphragm by differentiating the shape or type of material of a part of a voice coil bobbin from other part. CONSTITUTION:One end of a cylindrical voice coil bobbin 14 is inserted to a central projection 11b of a yoke 11 freely movably and a voice coil 15 is wound on the bobbin 14. A projection 14a to vary the mechanical vibration transmission characteristic is formed over the outer peripheral face of a part of the voice coil bobbin 14. Thus, the mechanical vibration transmission characteristic is different from the case with no projection 14a. That is, when no projection 14a is formed, a driving force generated from the voice coil 15 is transmitted as it is to a diaphragm 18. On the other hand, when the projection 14a is formed, the high frequency component in the vibration component generated in the voice coil 15 is varied by the voice coil bobbin 14, the high frequency limit frequency of a reproduced sound radiated from the diaphragm 18 is changed.
