Abstract: PURPOSE: To provide an inverter circuit capable of suppressing an input phase difference and power consumption by turning the stage number of an MOS inverter to one.

The inverter circuit is provided with the MOS inverter 11 of one stage, the input is connected through an input capacitance C1 to the V(aIN1) and the output is connected through a feedback capacitance Cf to the input. In this case, when a power supply voltage is defined as Vdd , the logical inversion output V' of the V(aIN1) is V'=Vdd -(C1/Cf)V(aIN 1), and as the result of comparing the V' and the V (OUT) by simulation by an analog circuit simulator, the V (OUT) is the satisfactory approximation of the V'. In such a manner, when weighted inversion by the MOS inverter I1 of one stage is used under appropriate using conditions, sufficiently high accuracy is obtained.

When the mold 1 lowers, the gap 7 between the slag rim 3 at the short sides 6 and the molten steel 2 is narrowed. Then, the upper part of the short side 6 sides is enlarged by using a width adjusting mechanism, etc., and the gap 7 is widened and the molten powder 5 is sufficiently flowed into the gap between the short sides 6 and the molten steel 2.  At the time of enlarging the upper end parts of the short sides 6 by about 0.5-2.0mm, since the flow-in of the molten powder 5 can be secured even in the casting at the high speed, such as >=1.5m/min, the casting can be executed which preventing the breakout, etc.

Inventor: HIRAO AKIRA
IPC: H04M3/00
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To reduce working time in the case of connecting a cable between communication controllers. SOLUTION: ISDN communication controllers 11 and 12 automatically identify an interface in the case of allocating a communication channel through a negotiation based on a common line signal. First of all, the ISDN communication controller 11 always transmits an interface identification number, which is individually allocated to each interface inside an interface group, while storing it in a frame and transmits a communication channel number while storing the interface identification number together at the time of negotiation for allocating the communication channel. When activating the interface, the ISDN communication controller 12 extracts the interface identification number, stores that number and further monitors it at all the time and when there is any change, the number is updated.  Afterwards, the interface is automatically identified based on the interface identification number stored at the time of negotiation for allocating the communication channel.
