Title: Numeral reception system
Inventor: SHIMOZONO RYOJI
IPC: H04Q3/545
Filed: 1990-03-15
Abstract: PURPOSE:To prevent the occurrence of mis-connection and to improve the reliability of an exchange by allowing a numeral receiver to store numeral information sent to a controller and collating the information with numeral information returned from the controller so as to confirm the normality of the numeral information received by the controller. CONSTITUTION:A numeral receiver 200 receives numeral information (x) reached from a communication line 100, sends it to a controller 300, and a numeral return means 301 returns sent numeral information (x) to the numeral receiver 200. A numeral storage means 201 stores the numeral information (x) sent from the numeral receiver 200 to the controller 300 and a collation means 202 collates the numeral information (x) stored in the numeral storage means 201 with the numeral information (x) returned from the controller 300. Then an exchange 1 confirms the normality of the numeral information (x) received by the controller 300 based on the result of collation by the collation means 202. Thus, occurrence of mis-connection is prevented and the reliability of the exchange 1 is improved.

Title: Lead free solder of high strength and low melting point
Inventor: WAIDE NOBORU
IPC: H05K3/34
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain solder of high strength and a low melting point by mixing/ adding Ag, Cu, Bi respectively in a specified ratio to Sn solder. SOLUTION: This lead free solder is produced by adding and mixing 0.5-3.0 wt.% Ag, 0.1-0.8 wt.% Cu (preferably 0.1-0.5 wt.%), 6-20 wt.% Bi (preferably 10-20 wt.%) to Sn solder (solder of single Sn). Ag improves the Sn strength as well as exhibits the prevention effect of Cu consuming. The Cu refines the structure to increase the ductility and further, exhibits the prevention effect of copper consuming of the solder. Bi significantly increases the high temp. strength, lowers the melting point and improves the soldering property. Concretely the solder of high strength and a low melting point, which has >=90 Nmm<2> at a room temp. and >=50 Nmm<2> at 125 deg.C, is obtained. By this method, even in the case that the working temp. of soldering is controlled, the solder can be used without any trouble.

Abstract: PURPOSE:To minimize the amount of hardware and to lighten the burden of the main controlling section, by performing the processing of the main controlling section firstly when processing requests are simultaneously inputted to the controlling section from external equipment and the main controlling section. CONSTITUTION:A sequencer 13 monitors whether there is any command from a central processing unit 1 or not or whether there is any I/O instruction from a main controlling section 4 or not. When an I/O instruction is issued from the main controlling section 4, a synchronizing circuit 11 which has received an I/O request signal from a processor controlling section 20 stops the execution of any microprogram to the sequencer 13. While the excution of the microprogram is stopped, the processor controlling section 20 performs the I/O instruction. Since the time required for processing an I/O instruction is extremely short in general, there will be no problem even when the processing of external equipment is discontinued.
