IPC: E03F3/04
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To lessen girder height and protect a flexible water sealing member by providing a joint frame body, an outer peripheral side receiving part support frame, an outer peripheral side receiving member, a flexible water sealing member and an inner peripheral side receiving member and providing the inner peripheral side receiving member with a push plate, a frame plate, a joint plate and a rib plate. SOLUTION: The frame plates 62, 63 of an inner peripheral receiving member 60 and the joint radial lengths of a joint plate and a rib plate 65 are formed smaller than the joint axial length of a push plate 61. Thereby the girder height of the inner peripheral side receiving member 60 can be suppressed at most half of the width of an inner peripheral flexible water sealing member. In addition, the push plate 61 of the inner peripheral side receiving member 60 adjacently arranged on the inner peripheral side prevents extension to the inner peripheral side by external water pressure of the inner peripheral side flexible water sealing member. An outer peripheral side receiving member 50 regulates extensio to the outer peripheral side of the inner peripheral flexible water sealing member by internal water pressure. Thus, girder height can be lessened.  In addition, the flexible water sealing member can be sufficiently protected in response to internal and external pressure.

IPC: H04B7/005
Filed: 1988-02-29
Abstract: PURPOSE:To simplify the adjustment of a reference level for detecting a signaling signal by passing an output voltage of a low pass filter through an AGC amplifier. CONSTITUTION:An input signal is inputted at first to a filter 14 being a narrow band pass filter. The filter 14 extracts a signaling signal from the input signal and gives an output to an AGC amplifier 18. A signal being a prescribed output by an AGC amplifier 18 is detected by a detector 16 and compared with a prescribed reference voltage Vref1 by a voltage comparator 17 and an H level signal is outputted at the reference voltage or over. Thus, the H level signal is outputted from the comparator 17 and the reception of the signaling signal is detected. Thus, the level difference of the signaling signal sent from each station is compensated and the reference voltage Vref1 of the 1st voltage comparator 17 is adjusted simply.

Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To make heat resistance excellent, restrain scorch, and make workability excellent, by combining graphitized carbon black of specific weight part with polyethylene of specific weight part. SOLUTION: The combined quantity of graphitized carbon black is set to be 30-100 wt.%, favorably 50-70 wt.% against single site catalyst polymerized polyethylene 100 wt.%. Namely when the combined quantity of graphitized carbon black is a small quantity under 30 wt.%, conductivity as a semiconductor layer becomes insufficient, meanwhile when it is a large quantity over 100 wt.%, viscosity of resin composition at melting becomes high to be difficult for extrusion molding. The graphitized carbon black is made by further processing carbon black such as furnace black at high temperature of 2000-3000 deg.C in the innert atmosphere, and crystal in a particle is grown while holding initial particle diameter. Consequently, impurities are reduced, heat resistance is improved, and adsorption of liquid or the like can be reduced.
