Title: Switchboard control system
Inventor: SUEZAKI EIICHI
IPC: H04M3/60
Filed: 1985-04-30
Abstract: PURPOSE:To realize a switchboard control system with economical and elastic in function by separating completely the function of the switchboard to the switchboard which handles only a switchboard process function and to the switchboard which exchanges only a general input/output connecting call, also with separating in a hardware and a software area. CONSTITUTION:In a switchboard B which handles a general exchange process, a switchboard connecting call arrived at an input trunk 20 as the special number call of the switchboard is processed as a general tandem connecting call for the switchboard B side. That is, as a connecting process, a control signal is sent to a switchboard A side which handles the switchboard connecting process, with in-channel, through digital trunks 19 and 18. At the same time with the control of a switchboard connecting operation, a charging process is performed at the switchboard A and a sequential process is completed. As a result, no switchboard connecting operation is performed at the switchboard B and the switchboard A is only operated to be handled as an other switchboard and it is absolutely no necessary to carry about or to process a control information at the switchboard B.

Title: Echo canceller
Inventor: NAGAI KIYOTAKA
IPC: H04B3/23
Filed: 1984-05-08
Abstract: PURPOSE:To obtain an echo canceller showing excellent converging characteristics and cancelling amounts by allowing the 1st adaptive transversal filter to apply adaptive control so as to minimize the residual signal of an input signal at the reception side and allowing the 2nd adaptive transversal filter to apply adaptive control to minimize an output signal at the transmission side. CONSTITUTION:The 1st adaptive transversal filter 11 applies the adaptive control to minimize the residual signal of the input signal at the reception side. Thus, the residual signal of the input signal at the reception side is a signal subtracting the correlation component corresponding to the tap numbers of the 1st adaptive transversal filter 11 from the input signal at the reception side. The 2nd adaptive transversal filter 13 uses the residual signal of the input signal at the reception side as the input signal and brings sequentially the output signal close to the echo signal generated on the echo pass by applying adaptive control to minimize the said output signal at the transmission side. Thus, this system is effective by using a signal itself having high correlativity such as a voice signal to estimate the transmission system.

Title: Liquid sampling tube
Inventor: SASAKI SAKAE
IPC: G01N33/48
Filed: 1989-04-12
Abstract: PURPOSE:To prevent sampled liquid from scattering out by arranging an elastic space formation body in the tube and wiping the tip of a liquid sampling needle when the needle is extracted. CONSTITUTION:The opening part 2 of a bottomed tube body 1 is closed with a sealing member 3, which consists of an annular cap body 4, a film member 5, and a resealing rubber member 6. Then the elastic space information body 8 is provided inside the member 5 to form a space 9 between the formation body 8 and member 5, and a blood absorptive member 10 is put in the space 9. Consequently, when the blood sampling needle 7 is removed, the sticking position of the formation body 8 deflects elastically toward the space 9 as the needle 7 moves in its extraction direction and when the tip of the needle 7 reaches the sticking position of the formation body 8, the formation body 8 wipes the tip with its restoring force, so that blood sticking the tip falls in the tube. Then when the tip of the needle 7 enters the space 9, it contacts the member 10 and sticking blood is further absorbed. Thus, wiping operation is performed twice and then when the tip of the needle 7 exits from the tube, there is a little sticking blood to securely prevent blood from scattering.
