Abstract: PROBLEM TO BE SOLVED: To suppress defects resulting from a solder not containing load to a minimum by soldering a substrate containing a copper-base terminal and a lead terminal containing a surface, comprising alloy of tin and copper together with a solder alloy of tin and copper. SOLUTION: Plural electronic parts 12 and mounted on a printed circuit substrate 10. Even electronic part 12 contains a lead 14 soldered to a terminal pad 16 of copper on the printed circuit substrate 10. This structure avoids the use of lead material which is environmentally toxic as a solder for attaching a lead terminal permanently to the terminal pad 16. Thus, a solder 18 inserted between an end of the lead 14 and the terminal pad 16 comprised a solder alloy of tin and copper, and relating to each lead of the electronic parts 12, a core is coated with such material which gets intimate with a solder as tin- copper alloy. Thus, the solder conforms with the copper terminal pad 16 and the lead 14 of the printed circuit substrate 10, so that by soldering, the solder 18 is permanently fused with each terminal pad 16.

Title: Automatic sidetone preventing circuit
Inventor: SEKI HIDEYUKI
IPC: H04M1/58
Filed: 1984-11-29
Abstract: PURPOSE:To obtain an excellent sidetone-proof characteristic without provision of plural balanced circuit networks by adding a signal of opposite phase to that of a transmission signal transmitted to a talking line to a sidetone preventing circuit depending on the quantity of a talking current. CONSTITUTION:The transmission signal outputted from a transmitter 5 is amplified by an amplifier 6 and transmitted to the talking line via a transmission signal output transistor (TR) 8 and a part of the transmission signal is fed to the side tone preventing circuit 13. On the other hand, since a signal having an opposite phase to that of the transmission signal appearing across a resistor 7 is fed to the circuit 13, the signals are added and the result is inputted to an amplifier 11. Thus, the phase difference is cancelled and the sidetone is suppressed. When the impedance of the talking line is changed, a part of the transmission signal to a balanced circuit network 10 is decreased. Since the signal of opposite phase is increased/decreased in matching with the transmission signal level changed depending on the quantity of the talking line impedance, the constant of the balanced circuit network 10 and the characteristic of an attenuator 9 are selected optimizingly.

Title: Hollow needle for liquid transfer
Inventor: SEKINE SHIGERU
IPC: A61J1/20
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To eliminate difference in pressure between the inside and outside of a vial for easier suction of injection liquid into the syringe by providing a groove from the sharp end toward the syringe side in the outer surface of a hollow plastic injection needle. SOLUTION: In a hollow plastic needle 1 for injection with one end connected to a syringe, a groove 3 is provided along the injection passage from its sharp end toward a connection 2 with the syringe in the outer surface of the needle 1. Upon penetration of the needle 1 into a vial, a gap though very small is produced between a cut section of the vial rubber plug (namely the groove) and the needle 1 or the plug and the rib-to-rib section in the needle outer surface. This eliminates the pressure difference which would otherwise be in presence between the inside and outside of the vial in the process of liquid medicine suction or medicinal solution injection, and facilitates the liquid medicine suction operation.
