Title: Liquid level detecting device
Inventor: OGUSU HIROYUKI
IPC: G01F23/26
Filed: 1991-06-05
Abstract: PURPOSE:To provide a level detecting device capable of detecting the contact of a probe top onto the level of a detected liquid at the time of lowering the probe toward the level of the detected liquid. CONSTITUTION:A metallic plate 5 is earthed near a vessel 4 in which a detecting liquid 4a is received, and the electrostatic capacity value between the metallic plate 5 and a level detecting needle 3 is differed depending on whether the level detecting needle 3 is in contact with a detected level 4b or not. A differential circuit 13 differentiates the signal oscillated by an oscillating circuit 6 according the electrostatic capacity value, wherein the sensitivity to the input frequency is set in such a manner as to be increased by the oscillated signal from the oscillator circuit 6 at the time when the level detecting needle 3 is in non-contact with the detected level. Thus, when the level detecting needle 3 makes contact with the detected level 4b, the sensitivity of the differential circuit 13 is reduced, and its output is also changed. This output change is detected by a voltage detector 14, whereby the level 4b can be detected.

Filed: 1983-07-25
Abstract: PURPOSE:To improve the S/N ratio and to ensure detection of coordinates with high accuracy by giving an inclination to the potential within a resistance sheet and eliminating the area of zero potential. CONSTITUTION:Analog switches 39 and 40 are opened and closed respectively, and at the same time an analog switch 31 conducts with an analog switch 32 cut off. Therefore a current approximately proportional to the voltage of the positive side where the half wave rectification is given to the output voltage of an oscillator 28 is supplied to an output terminal 36 of an amplifier 35 from an amplifier 33 through a diode group 22, a resistance sheet 21 and a diode group 24 as long as the amplifier 33 is equal to a non-inverse amplifier. As a result, a potential gradient having a fixed lateral inclination is produced on the sheet 21. Thus the position of an electric pen 42 can be detected accurately with high S/N ratio by making use of said potential slope.
