IPC: F16K5/06
Filed: 1988-11-28
Abstract: PURPOSE:To maintain the sealing quality of a seat at a high temperature time such as a fire or the like and realize the prevention of damage, by forming out of a heat expansion material a seat either on the closing member side or the valve main body side of a valve which opens/closes by means of a valve shaft 90 degree/180 degree rotation operation. CONSTITUTION:When a butterfly valve 1 is heated by a fire or the like, a seat 4 of a heat expansion material expands, and seals firmly a space between a valve main body 2 and a disk 3, so a sure sealing is done even if the seat 4 is worn and damaged, and the passing of a fluid is deterred. If black lead which is of a heat expansion quality is used as a heat expansion material, it does not become ashes nor burn out at a high temperature, and its volume almost does not increase/decrease from a temperature change after heat expansion, and there is no occurrence of leak even after a temperature drop. When a sheet 4 is formed by putting a metal plate or metal foil 4a on a thin plate shaped heat expansion material 4b in layers, materials are hard to crumble after heat expansion, and the quality of sealing increases. Accordingly, damage due to the breakage of the valve or the like can be prevented.

IPC: H04L7/033
Filed: 1987-11-26
Abstract: PURPOSE:To obtain a system clock with an optimum phase to a reproduced data by utilizing it that a control voltage applied to a voltage controlled oscillator is nearly proportional to the steady-phase error of a phase locked loop. CONSTITUTION:A control voltage applied to a VCO 9 is subject to A/D conversion 12 and the result is given to a magnitude comparator 13. On the other hand, the oscillated output of the VCO 9 is given to delay lines 14-16 connected in n-stage in cascade and n-set of clock signals with deviated phase are fed to a selector 17. The controlled voltage is nearly proportional to the deviation of the oscillated frequency with respect to the self-running frequency and the control voltage is nearly proportional to the steady-state phase error. Thus, the relation of phase between the clock 2 given to an elastic buffer 4 and the system clock 19 is kept constant independently of the deviation of the frequency of the recovered clock 2 given to the phase comparator 5 with respect to the self-running frequency of the VOC 9.
