Title: Magneto-optical memory device
Inventor: IDE TSUGIO
IPC: G11B11/10
Filed: 1990-05-11
Abstract: PURPOSE:To secure a constant level of field intensity at the position of a laser beam spot by using a magnet movable type lens focusing actuator, measuring the moved variable of an objective lens which is driven by the face wobbling of a magneto-optical disk, and controlling the position of a magneto-optical disk. CONSTITUTION:The moved variable of an objective lens 4 is obtained by measuring the intensity of a magnetic field generated from a mobile magnet 1 by a Hall element 9 set at a fixed part. The field intensity varies at the position of the element 9 in proportion to the variance of the distance between the magnet 1 and the element 9. Thus the face wobbling of a magneto-optical disk 10 can be indirectly measured. A magnetic head 11 for modulation of magnetic field can move in the face wobbling direction of the disk 10 by a magnetic head actuator 12 applying a stepping motor. The stepping motor is driven by the control signal produced from the output of the element 9 so that a constant distance is secured between the disk 10 and the head 11. As a result, the impressed field intensity is kept constant on a recording film.

Title: Method for analyzing quantity of phosphoric acid in exhaust gas of fuel battery
Inventor: SADO NAOHIKO
IPC: G01N30/08
Filed: 1984-06-14
Abstract: PURPOSE:To improve the collecting efficiency of phosphoric acid mist or vapor in exhaust gas and to attain rapid quantitative analysis by heating a conduit coupled with the outlet side of exhaust gas so that the temperature of the exhaust gas is kept at a temperature near the working temperature of a fuel battery. CONSTITUTION:Exhaust gas 20 including phosphoric acid mist exhaused from the exhaust gas outlet 5 of the fuel battery 1 and formed water vapor is carried from a conduit part 6 to a condenser 8. The conduit part 6 is kept at its temperature by a ribbon heater and an insulating material so that the exhaust gas 20 is kept at a temperature close to the working temperature (about 180-210 deg.C) of the fuel battery 1 and its inwall is prevented from the adhesion of phosphorous mist or vapor. The condenser 8 is stored in a cooler 9 so that the exhaust gas 20 is cooled to condense and liquefy the formed vapor and the phosphoric acid mist is dissolved in the condensed solution to collect the mist as a phosphoric acid solution 11. The collected solution 11 is sent to an analyzer 15 such as an ion chromatography to find out the quantity of phosphoric ion in the delivered solution and convert the ion quantity into the quantity of phosphoric acid. Since the required volume of the solution may be 1ml or less, a time required for the collection can be shortened.
