Title: Charge detector
Inventor: TAKAHASHI SHIGEKI
IPC: H01L21/66
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To detect an external microcharge smaller than an element charge even under room temperature by providing first and second members where the distance is variable depending on the magnitude of Coulomb interactions and measuring variation in the physical properties due to variation in the quantity of charges of first member caused by external charges directly or indirectly. SOLUTION: Assuming a microparticle 13 is charged with a quantity of charges q1 and a microparticle 15 is charged with a specified quantity of charges q2 , q1 /q2 =(r1 /r2 )<2> is satisfied through Coulomb interaction between the particles. Since the quantity of charges q2 and the value r1 +r2 are constant, position of a microparticle 14 is determined uniquely for the variation in the quantity of charges q1 . Consequently, when the position of microparticle 14, i.e., the distance r1 between the microparticle 13 and 14, is measured accurately by means of a probe 19, the quantity of charges q1 of microparticle 13 is determined and thereby microcharges smaller than the element charge can be detected accurately.

Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To drive a spool of a servo valve continuously by branching off a desired value into two parts, adding a bias signal to each signal whose one side is inverted, and controlling a volt-ampere converter for an electromagnet after getting these signals passed through a subtractor for load current feedback and a comparator for pulse width modulation. SOLUTION: A desired value Vi with the polarity extending over positive and negative is branched off into two parts before being added with a constantly set bias signal Vb , and one side comes to a signal Via as it is, but the other comes to a signal Vib with a code turned over. These two signals Via and Vib , after the bias signal Vb is added thereto, is subjected to minus in feedback a load current and is turned into a superposing signal, and then they pass through two pulse width modulating compactors 57 and 57' and are turned to control voltage, through which they control the current of an electromagnet by way of two volt-ampere converters 58 and 58' for each electromagnet. Here, when the desired value Vi is zero, a current equivalent to the bias signal Vb flows into each electromagnet with a constant current characteristic.
