Title: Bidirectional deflection system
Inventor: HIRAHARA HIROAKI
IPC: H04N3/23
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To improve the linearity of a scanning line by a simple circuit without using an auxiliary coil by superimposing the current of a polarity opposite to a horizontal deflection current on a vertical deflection current. SOLUTION: The fluctuation value of peak-to-peak over several hundreds V of the voltage waveform VH of a horizontal deflection drive circuit 4 is converted to about 5 V by a voltage adjustment circuit 15, inverted output (m) is supplied to a drive circuit 16 and an output drive voltage (n) is supplied to a transformer 17 for correction current superimposing. Since a phase is delayed for 90 deg. by a voltage for a current flowing to a coil, a correction current component ILV flowing to a vertical deflection yoke LV becomes the opposite phase of a horizontal deflection current component indicated by a broken line (p) on the vertical deflection current. Thus, a cancellation current ILV is superimposed on the vertical deflection current ILV, horizontal deflection components are cancelled and excellent linearity characteristics are obtained.  Thus, the linearity is improved without providing the auxiliary coil requiring the drive circuit of large output.

Title: Pressure float concentration apparatus
Inventor: YONEDA MASANOSUKE
IPC: C02F1/24
Filed: 1983-08-01
Abstract: PURPOSE:To compensate a leak by balancing the inflow amount and the outflow amount to a pressure tank, by mutually interlocking a vacuum pump and a booster pump through a differential gear apparatus. CONSTITUTION:For example, when a leak is generated from the high pressure side to the low pressure side in a booster pump 8, the outflow amount from a pressure tank 7 by a vacuum pump 14 increases in quantity as compared with the inflow amount into the pressure tank 7 by the booster pump 8. As a result, the water level in the pressure tank 7 gradually lowers. This lowering in the water level is detected by a level meter 17 and an operation gear apparatus 15 is controlled by a control apparatus 18 and the speed of the booster pump 8 is made faster than that of the vacuum pump 14 to supply pressurized water into the pressure tank 7 in an amount corresponding to the lowering amount of the water level. By this mechanism, the water level in the pressure tank 7 is held and a predetermined amount of pressurized air-dissolved water can always be supplied to a mixer 2.
