Title: Noise filter
Inventor: HARADA TORU
IPC: H03H7/09
Filed: 1987-03-06
Abstract: PURPOSE:To attain the rejection of noise at a low frequency and a high frequency with small size and low cost by connecting a series connection comprising an auxiliary coil and a capacitor in parallel with a main coil. CONSTITUTION:The series connection 9 comprising an auxiliary coil 7 and a capacitor 8 is connected in parallel with a main coil 5 of a noise filter 1. The capacitor 8 is selected so that the resonance frequency by the capacitor 8 and the main coil 5 is selected to be, e.g., 0.06MHz. Moreover, the auxiliary coil 7 is selected so that the impedance Z at a high frequency band is large and the impedance Z is small at the resonance frequency by the capacitor 8 and the main coil 5. Thus, noise at a prescribed low frequency band is rejected by the parallel resonance by the capacitor 8 and the main coil 5 and the noise at a high frequency band is rejected without being bypasses by the capacitor 8 because of a high impedance of the auxiliary coil 7.

Title: Surface potentiometer
Inventor: YOKOMIZO YOSHIKAZU
IPC: G01R29/12
Filed: 1979-04-27
Abstract: PURPOSE: To accurately set the relative relation between the actual surface potential and a detecting potential by providing a grid at the detecting opening of a potentiometer and applying a bias voltage thereto to eliminate the offset phenomenon.  
     CONSTITUTION: When the opening 2 of the case 1 of a surface potentiometer is approached to the surface of an object to be measured, an electric field is induced between an electrode 6 and the object. When the electric field is crossed by rotating blades 5, an infinitesimal alternating signal proportional in amplitude to the intersity of the electric field is induced at the electrode 6. In order to judge the positive or netative of the electric field, the potential of the electrode 5 at the moment when the opening 2 is closed by the blades 5 is defined as zero potential. Therefore, a synchronous signal is formed by an optical path 14 opened at the moment when the opening 2 is closed by the blades 5, and the alternating signal is instantaneously clamped to zero from an amplifier 11 via a synchronizing clamping circuit 16. When the waveform of the signal is integrated by an integrator 17 with the zero potential as a standard, a DC output proportional to the surface potential of the object to be measured can be obtained at the output terminal 18. At this time the residual voltage at the electrode 6 is cancelled by applying negative potential to the grid 4.
