Abstract: PURPOSE:To ensure conductivity between a body and an opening/closing unit such as a front cover, etc., and to prevent leakage of an electromagnetic wave by allowing a protrusion in side contact with the inner peripheral side of a conductive sealing member from the inner edge of the opening of the body or the unit. CONSTITUTION:After the guide 2C of a protrusion 2A of a front cover 2 is disposed inside a tubular part 4A of a conductive sealing member 4 extended to the opening of a body 1, the cover 2 is pressed to the body 1. Then, the protrusion 2A is smoothly inserted into the body 1 through the guide 2C of the cover 2. When the guide 2C is then passed through the part 4A, the protrusion 2A applies a pressing force to the part 4A from the inside to the outside to insert the part 4A into the body 1 while elastically deforming it. In this case, since the protrusion 2A is brought into slidable contact with the member 4, the member 4 and the part 2A are cleaned therebetween improving the conductivity between the body 1 and the protrusion 2A, i.e., the front cover 2. Thus, leakage of electromagnetic wave is prevented.

IPC: G06F15/00
Filed: 1988-09-16
Abstract: PURPOSE:To avoid input mistakes by transferring information on the key corresponding to the designated key display after setting the information into a telegram requesting the next retrieval. CONSTITUTION:When a retrieval key A is designated by a terminal equipment 2, a center 1 transfers the key A and the attribute information (a) and also sends the keys B and C pointed by the key a to the equipment 2. The equipment 2 displays these received keys on a display 8 via a telegram reception processing part 5-1 and a screen edit processing part 7. When the display of the key B is instructed on the display 8 under such conditions, the part 7 retrieves a display position table 6 to decide the identity of the key B and sets this key on a retrieved key table 9. Thus a telegram transmission process part 5-2 sets the key B into a telegram 4-2 for retrieval of a data base 3 and transfers it to the center 1. In such a constitution, the keys corresponding to the key display are recorded to the equipment 2 and therefore the input mistakes can be avoided.
