Title: Soundproof double floor
Inventor: NAKAMURA KOSUKE
IPC: E04B5/43
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To improve soundproof ability in a low tone sound range while keeping rigidity by laying rubber vibration isolator between a floor base material and a floor substrate, and disposing a vibration isolator with fluid sealed in a cavity defined by an elastic body in parallel with the rubber vibration isolator. SOLUTION: Rubber vibration isolator 3 and an antivibration device 4 with fluid sealed in a cavity defined by an elastic body 5 are interposed in parallel between the floor base material 1 and the floor substrate 2. Thus, an vibration isolating effect can be obtained when vibration is propagated from the floor base material 1 via the rubber vibration isolator 3. Through damping action brought about flow of sealed fluid in the vibration isolator 4, a vibration level of the floor is decreased; in particular, a sound insulation ability is enhanced in the low tone sound range. In this case, a spring constant of the vibration isolator 4 in the load direction is made 2.0×10<5> N/m or less, and a loss factor is made 0.5 or more, thereby maintaining the rigidity of the whole floor, and also enhancing load bearing performance and walking feeling.  In addition, a viscous coefficient of the fluid to be sealed in the cavity 6 is made 0.1Pa.S or more. In this way, a damping effect brought about by flow of fluid is facilitated to develop more easily.

IPC: H04J3/06
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To obtain a synchronous system between private branch exchanges, that prevents interference by a radio wave. SOLUTION: A private branch exchange 1 transmits a signal (a) in faster timing than a master frame pulse by a prescribed phase difference to a private branch exchange 2.

The phase synchronization oscillator 22 generates the 5 ms frame head signal synchronously with the received 5 ms frame pulse and transmits it to PHS base station interfaces 24, 29 via PHS base station interfaces 23, 28. When the phase relation between the slave frame pulse (a) and the loopback frame pulse (b) is symmetrical to the master frame pulse, 5 ms frame synchronization is competed between the phase synchronization oscillators 12, 22.
