Title: Female terminal metal fitting
Inventor: NAKADA HIROYUKI
IPC: H01R13/11
Filed: 1995-02-22
Abstract: PURPOSE: To raise the bumps prevention effect of male terminal metal fittings without incurring the increase of formation process while securing current capacity enough, and lessen the resistance of engagement with the male terminal metal fittings. CONSTITUTION: This female terminal metal fittings are made of plate-shaped deformed materials different in thickness. Since a great part of a terminal engaging part 24 and a cable connection 21 are thick, large current capacity can be secured. Since an elastic contact part 32 and the brim 25A of an insertion port 25 are thick, the elastic force of the elastic contact part 32 becomes weak, and the resistance of engagement with male terminal metal fittings is small, and the opening area of the insertion port 25 becomes wide, and the bumps of the terminal metal fittings to the brim 25A are hard to occur. Since a deformed material is used, hammering for thinning the thickness of the brim 25/a of the insertion hole 25 is needless, and the drop of molding efficiency caused by the increase of working processes can be avoided.

Filed: 1989-03-13
Abstract: PURPOSE:To improve the processing speed of an address transition detection circuit (ATD circuit) by providing a cascode amplifier to receive a pulse current from the voltage / current conversion circuit of an input signal and to execute voltage / current conversion. CONSTITUTION:A cascode amplifier 3 is provided to receive the pulse current, which is generated from voltage / current conversion circuits (1-1)-(1-n) by the voltage change of input signals A11-A1n, and to execute the voltage / current conversion. Concerning respective signals to detect the change, the voltage change is once converted to the current pulse respectively and these current pulses are added by a node for which a potential is almost fixed. Then, the added current is converted to the voltage. Accordingly, since a voltage amplitude is reduced to several ten of mV in the input end of the cascode amplifier 3, the influence of a load is not almost received and the signal can be transmitted at high speed. Thus, the processing speed of the ATD circuit can be improved.
