IPC: H01L25/00
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce work man-hour while keeping high reliability without impos ing thermal stress onto an electronic part by clamping an upper control circuit board at the shelf receiving part of an insulating resin case and connecting it electrically with a lower electric circiut with a bonding wire through a cut made in the circuit board. SOLUTION: A shelf receiving part 14 is provided on the inner side face of an insulating resin case 2. A cut 17 is made in the end part of a control circuit board 8 clamped on the shelf receiving part 14. In this regard, a gap 18 is formed between the end part of the shelf receiving part 14 and the end part of the cut 17. An interconnecting chip 15 is connected, through the gap 18, with a conductor pattern on a heat dissipating plate located below by means of a bonding wire 16. Consequently, the control circuit board 8 located above is connected with an electric circuit located below without requiring any terminal also serving as a post. Furthermore, labor can be reduced and an electronic part is not subjected to excessive thermal stress because soldering between upper and lower conductor patterns is required.

IPC: H03K19/013
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To improve the data signal speed of an open-drain architecture communication system by providing a circuit which monitors a through rate on an open-drain signal line and a circuit which provides a pull-up current for the open-drain signal line in response to the monitored through-rate. SOLUTION: Transistors(TR) 41 and 42 of a pull-up circuit 40 constitute a current mirror. When all open-drain drivers TRs connected to the signal line 1, e.g. a TR 14 is turned off, a capacitor 18 begins to charge itself with the collector current I2 of the TR 42, and a voltage on the signal line 11 increase. When the voltage on the signal line 11 exceeds the base-emitter voltage drop of a TR 43, the TR 43 is energized and sends a current I3 out via a resistance 47. The total of the currents I1 and I3 flows through the current mirror TR 41, and then the current I2 is increased to charge the capacitor 18.
