Abstract: PURPOSE:To attain accurate focusing at high speed access by using an offset voltage at high speed access up to this side of an object access position and matching a focus at a point deviated a little from a proper focus so as to move the optical head. CONSTITUTION:In applying high speed access to a prescribed tack, a switching signal is applied to a reference signal generating circuit 37 from a CPU and a bias voltage  x as a reference signal is changed into  x+a from a reference signal generating circuit 37 and outputted to an adder 36. The adder 36 outputs a signal being the addition of an out of focus detection signal from a differential amplifier 33 and the bias voltage  x+a to a phase compensation circuit 38. A drive circuit 39 applies a prescribed current to a coil 24 in response to the signal from the phase compensation circuit 38 to drive vertically on objective lens 16 for focusing. As a result, the beam spot by the objective lens 16 is corrected by the bias voltage so as to bring the focus to a position deviated a little from the optimum position.

Abstract: PROBLEM TO BE SOLVED: To detect dioxin or the like without using a high-resolution magnetic field type mass spectrograph by ionizing dioxin or the like that is an organic chlorine compound using negative corona discharge and observing the change in the amount of current due to the generated negative ion. SOLUTION: A gas sample through a sample heating furnace 3 is introduced to a corona discharge part 7 for ionization. The tip of a gas sample introduction path 8 is located near a wire electrode 11 for corona discharge and the diameter of the tip is small with a constriction, thus securing introducing the gas sample to a discharge region. Temperature is maintained at 50-300 deg.C by a corona discharge part heating heater power supply 10 and a corona discharge part heating heater 9. A negative high voltage is applied to the wire electrode 11 by a power supply 12 for corona discharge. The high voltage depends on the distance between the wire electrode 11 and a counter electrode 16 but is approximately -1--6 kV. The distance should be approximately several mm.  A metal wire heater 5 for heating a gas sample is controlled to 50-400 deg.C by a metal wire heater heating power supply 6, thus preventing particles from being introduced into a corona discharge region.
