A lubricant 16 is applied to the inner surface of the stiffening pipe 11, and a space part 20 inside the stiffening pipe 11 is filled with a sound absorbing material 13. For the sound absorbing material 13, a porous material (wet rock wool) is used. Even if the shaft 12 of the brace 10a is exerted with an axial compressive force and bound by the stiffening pipe 11 and the corners of the shaft 12 at ends on both sides make direct contact with the interior walls of the corner parts of the stiffening pipe 11, they slide without resistance because of the lubricant 16 applied to the inner surface of the stiffening pipe 11, thus reducing frictional sound, and causing the frictional sound generated to be absorbed by the sound absorbing material 13 packed. Also, a lid 14 and the sound absorbing material 13 itself can prevent the degradation of the lubricant 16 by preventing the influence of outside air.

Title: Modulator and demodulator switching system
Inventor: FURUKAWA MASATO
IPC: H04B1/74
Filed: 1989-12-28
Abstract: PURPOSE:To attain high speed switching by selecting an active MODEM and a standby MODEM so that a center MODEM with high priority is always backed up when a fault takes place to two center MODEMs or over. CONSTITUTION:When a fault takes place in a MODEM 1, a control section 1d controls a changeover sections 7, 8 to select themselves to the position of a standby MODEM 5 by a signal from a MODEM fault detection section 13. Thus, the MODEM 1 is backed up by the standby MODEM 5. Conversely, when the priority of the MODEM 2 is higher than the priority of the MODEM 1, the control section 14 restores the changeover sections 7, 8 to the position of the MODEM 1 and selects the changeover sections 9, 10 to the position of the standby MODEM 5. Thus, the MODEM 2 is backed up by the standby MODEM 5. Then a faulty MODEM is replaced into the standby MODEM properly in a short time according to the predetermined priority.
