Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To accurately detect only a spark by neglecting noise other than the spark in an electrostatic printer. SOLUTION: An envelope detection means 17 detects the envelope of the DC component of a current flowing to an electrode to which high voltage is applied and a signal comparing and preparing means 18 separates the envelope signal outputted from the envelope detection means 17 into a first signal S1 having the same phase as the envelope signal and a second signal S2 delayed in phase as compared with the signal S1 to output both signals. A signal comparing means 19 operates the signal level difference between the first and second signals S1, S2 outputted from the signal comparing and preparing means 18 and outputs a spark detection signal when a state such that the signal level difference becomes a predetermined value or more continues for a predetermined time or more.

Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To provide an actuator driving circuit using shape memory alloy by which linear displacement characteristics can be realized based on an input signal. SOLUTION: An operating member 1 consisting of wires made of a shape memory alloy is displaced by heating and cooling, and displacement X is provided with displacement characteristics X=aI2 ((a) is constant) in proportion to the square of currents I. When a position instruction signal P1 is inputted, a driving signal P2(P2=b×(P11/2)) of 1/2 squares of the inputted position instruction signal P1 is outputted from a compensating circuit 8 having linear characteristics. The signal P1 is compensated by the compensating circuit 8, and converted into the signal P2, and the driving current Ip is supplied to an operating member 1 in proportion to the signal P2.  The characteristics of the displacement X of an object to be controlled which is viewed for the position instruction signal P1 are turned into linear current displacement characters obtained by synthesizing the transmission characteristics of the compensating circuit with the current displacement characteristics of the operating member made of the shape memory alloy. Thus, the displacement X of an object 2 to be controlled in proportion to the inputted position instruction signal P1 can be obtained.
