  • Patent number: 5067007
    Abstract: Attempts have been made to increase the number of pins of packages accompanying the trend toward fabricating integrated circuits highly densely and in smaller sizes. The present invention provides technology for improving reliability in fabricating packages of the surface-mounted type that have increased number of pins. That is, when the packages are mounted on the wiring substrate, the lead pins that receive load from the axial direction exhibit bending strength which is smaller than the junction strength of solder at the junction portions. To achieve this object, the lead pins are made of a material having large resiliency such as a fiber-reinforced material, a transformation pseudo elastic material, an ultra-high tension material, or a heat-resistant ultra-high tension material.

  • Patent number: 4726013
    Abstract: A time division multiplex telecommunications system is disclosed as adapted for a key telephone system providing for intercommunication between any two of a series of key telephone sets in cascade connection to a switching control circuit, possibly with facilities for association with the nationwide telephone network. The control circuit receives from the tandem connection of telephones an outgoing data signal of time division multiplex frame format having a succession of frames each comprising a frame sync signal and channels of outgoing data from the respective telephones. Rearranging the channels of data in the received outgoing data signal, the control circuits delivers back to the successive telephones an incoming data signal of similar frame format. Each telephone is equipped for rearrangement of the frame sync signal and data channels of the incoming and outgoing data signals, with the result that all the telephones can be of the same circuit configuration.
