Filed: 1988-09-30
Abstract: PURPOSE:To shorten maintenance time by outputting the contents of an address switch as an output interface signal in the title modem by a data terminal ready signal from a communication control equipment to the modem. CONSTITUTION:When the data terminal ready signal to be sent from a communication control unit 2 onto a signal line 201 is an OFF state, a selector circuit 15 selects the contents from an address switch 16, sends information to indicate that the contents of the address switch 16 are selected from a driver circuit 12 through an output interface signal line 210 to the communication control unit 2, and informs the communication control unit 2 of the information. Consequently, the connection between the communication control unit 2 and a modem 10 can be easily confirmed by previously setting a value intrinsic to the modem 10 itself to the address switch 16 of each modem 10. Thus, the validity of the connection can be easily checked, and time to be spent for the examination can be shortened.

Inventor: TSUJI MASAHIRO
IPC: B23K1/00
Filed: 1985-11-06
Abstract: PURPOSE:To improve the plating performance of leads for a semiconductor or a ceramic package type and to entirely obviate the generation of abnormality by brazing by maintaining the dew point of an atmospheric gas for brazing at <=-50 deg.C. CONSTITUTION:The dew point of the atmospheric gas for brazing is maintained at <=-50 deg.C in the stage of brazing the leads for the semiconductor to ceramics in a non-oxidizing atmosphere. The moisture contained in the atmosphere increases to >=0.004vol.% and the Si and Al in the Fe-Ni alloy used as the lead material are concentrated to form he oxide on the solder surface in the stage of brazing. Such oxide, when formed, is a cause for the generation of the abnormality in plating. The formation of the oxide is, therefore, prevented by maintaining the dew point at <=-50 deg.C, by which the generation of the abnor mality by brazing is entirely eliminated.
