摘要:
A lower part 14L of a band way 14, which is incorporated in an arch unit 12, is separated from the other parts of the band way 14. A drive (air cylinder) 35 supports the lower part 14L, allowing the same to move between a substantially horizontal initial position and an inclined position. A band 13 is released from the band way 14 when a packing operation starts. Thereafter, the lower part 14L is moved from the initial position to the inclined position and compressed air is applied to the guide surface 14a of the lower part 14L, thereby removing foreign matter from the band way 14. This sequence of removing foreign matter is performed in, for example, each cycle of packing operation.

摘要:
In the construction of a damper assembly for musical instruments, the conventionally used swingable damper lever for operationally relating a key to an associated damper wire is omitted and the swing movement of the key is either directly and indirectly converted into a corresponding fairly vertical movement of an elongated damper holder via a balance weight disposed to the bottom end of the damper holder in order to avoid undesired influences caused by swinging movement of any mechanical parts. Use of a plate type damper holder further advantageously prevents undesirable twist and dancing of the damper holder. Simultaneous, even and well-controlled pressure contact of the damper head with the vibrating string assures ideal damping and acoustic effects and use of detachable balance weight enables free adjustment of touch on the key.

摘要:
The present invention provides a duplexed operation processor control system that includes operation processors, an I/O device, and at least one communication path that couples the operation processors to the I/O device, and at least one communication path that couples the operation processors with each other. The duplexed operation processor control system switches over either of the operation processors to be a primary operation processor that executes a control operation for a control target, and the other to be a secondary operation processor that is in a stand-by state, and the secondary operation processor snoops control data synchronously when the primary operation processor acquires the control data from the control target.
