IPC: B65D88/78
Filed: 1977-09-30
Abstract: PURPOSE: To make the thickness of a membrane thin, eliminating the problems about buoyancy and the strength against water pressure, by allowing a thin-membrane tank to retract in absence of liquid in the thin-membrane tank, when liquid is stored in the tank formed of soft thin membrane in water.  
     CONSTITUTION: When liquid 20 is introduced through a valve 19 and a fixing pipe 11, a thin-membrane tank 6 swells, and liquid 20 can be stored to the full of the inner volume. At this time, the thin-membrane tank 6 is protected by a tank protecting membrane 5 for the swelling over the maximum permissible volume or the injuries due to external force. When liquid 20 is discharged outside, the thin-membrane tank retracts according to the discharged amount, and according to said retraction, water gets into the protection membrane 5 from a water-through hole 7, and the liquid pressures inside and outside the thin membrane 6 are balanced. A protection box 10 having liquid permeability is formed in the protection membrane 5 so that the thin-membrane tank 6 having retracted does not close the opening part of the pipe 11, and the discharge of the liquid is made easy

IPC: H01R43/20
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To improve reliability in engagement by forming, in a counter surface, a projection lead hole that is connected with a guide hole in order to receive, guide, lead a projection during initial time of engagement, is positioned between contact insertion holes, and has a width larger than the guide hole. SOLUTION: Because a pair of projection holes 42b, 42c of a counter connector 30 are positioned outside a contact insertion hole, the pair of projection lead holes 42b, 42c are tapered widely to be enlarged. Therefore, even when plate lead holes 40a have an extremely small width, a shield plate 20 can be easily inserted into the plate lead hole 40a. Because width of the plate lead holes 40a can be decreased, contact lead holes 34a positioned between the plate lead holes 40a can be formed widely by the decreased width in the row direction. Therefore, a contact 14 and a shield plate 20 can increase their lead hole to improve reliability during engagement.
