Title: System for oscilloscope signal input
Inventor: TAKESHITA SHIYUUJI
IPC: G01R13/22
Filed: 1981-03-30
Abstract: PURPOSE:To lessen the influence upon a circuit to be measured and to improve the measurement precision, by providing an offset voltage applying means on the signal path from the tip of a probe to the signal input part of an oscilloscope. CONSTITUTION:The signal applied to a signal contact terminal 3 of a probe 1 is inputted to an adapter part 8 through a probe input resistance 5 and a signal cable 7 and is inputted to an input resistance 6 of an oscilloscope 2 through a mercury cell 9 of, for example, 1.3V. The output level of an ECL logical circuit to be measured is fluctuated in a range -0.8--1.8V, and the threshold level is -1.3V. When the output level of the circuit to be measured is -0.8V, 1mA is flowed to the oscilloscope side; and when the output level is -1.8V, 1mA is flowed to the circuit side reversely; and when the output level is the threshold level, no current is flowed in and out. Thus, the current flowed in and out between the circuit to be measured and the oscilloscope is reduced to lessen the influence upon the circuit to be measured.

IPC: F04D29/06
Filed: 1981-04-01
Abstract: PURPOSE:To enable to keep the gap between a runner and a casing liner of a pump substantially constant, by exchanging heat between water used for lubricating bearings of the pump and water to be conveyed by the pump, and feeding the bearing lubricating water to the pump after bringing the temperature of lubricating water near to the temperature of water to be coveyed by the pump. CONSTITUTION:Lubricating water supplied into a protective pipe 7 flows downward as shown by arrows in the drawing, and after lubricating bearings 9, 10, is discharged to the back side of a runner 11. Thus, since the lubricating water flows along the outer surface of a main shaft 12 in the protective pipe 7, temperature of the main shaft 12 is made subtstantially equal to the temperature of lubricating water. On the other hand, since the main body of the pump including a casing 14 and a lifting pipe 15 is immersed in water in a pit 2 to be conveyed by the pump, the temperature of the main body of the pump is made substantially equal to that of water in the pit 2. Further, since a part of a lubricating- water feeding pipe 1 is immersed in water in the pit 2 and heat is exchanged between the lubricating water and water in the pit 2, the temperature difference between them is reduced, so that the gap G between the runner 11 and a casing liner 16 can be kept substantially constant.
