IPC: H04Q3/58
Filed: 1988-09-30
Abstract: PURPOSE:To enable anyone to input data by inputting system data and terminal data by means of a voice. CONSTITUTION:When the system data and terminal data are inputted from a key telephone system 100, main equipment 200 is set at a data input mode beforehand. When the data are inputted by the voice of a programming human being through a microphone 101 at the key telephone system 100, voice signals are converted into digital voice signals by an A/D converting circuit 103 and transmitted to the main equipment 200. At the main equipment 200, a pattern collating circuit 201 collates a standard pattern digital signal registered with a standard pattern circuit 202 beforehand with the received digital voice signal, and when they correspond, the collation consistent standard pattern digital signal is written into a memory circuit 205. Thus, the correct data can be inputted without depending on the degree of the experience of an operator.

Title: Carry chaining addition circuit of precharge type
Inventor: IKUMI NORIYUKI
IPC: G06F7/506
Filed: 1983-12-24
Abstract: PURPOSE:To reduce power consumption and make high-speed operations possible to enhance the operation speed by constituting a precharge-type carry adder, which consists of an N type MOSFET, with a CMOS circuit. CONSTITUTION:When deletion of carry occurs in the least significant digit, a carry passes three stages of transfer gates (TG) in a least significant adder group CG0 and passes TGs TG2-TG4 thereafter and is branched into two, and one passes TGs TG5 and TG6 and the other passes TGs TG10 and TG8. Then, carries passing the same number of stages reach individual nodes in both sides of a TG TG7. Signals of level ''0'' are given to an adder group CG6 from both of the lower side and the upper side, and the value of each node is established after a delay corresponding to two stages of TGs. Consequently, the carry passes only 10 stages of TGs in total in this case. As the result, the number of passing stages of TGs is reduced from 31 to 10 in the worst case, and it is sufficient if the carry output passes 7 stages of TGs.
