摘要： PURPOSE:To polish by profiling to the surface shape of a lens even if its shape is slightly changed by providing a means for gradually feeding a polishing tape while giving a constant tension and reciprocating movement to the polishing tape by a hysteresis clutch. CONSTITUTION:A lens 1 is polished by using a polishing tape 2 in the state of the lens 1 being rotated by fitting it to a turntable 9. In this case, a current passed to hysteresis clutches 3A-3D is controlled and the polishing tape 2 is gradually fed out by a feeding means while a constant tension and reciprocating movement is given to the polishing tape 2. By interlocking with this the polishing tape 2 advances and retreats, and an abrasive liquid 16 is fed to the polishing tape 2 by the driving of a pump. Polishing can thus be made by profiling to the surface shape even if the shape of the lens 1 is slightly changed by feeding out the polishing tape 2.

摘要： PURPOSE:To accurately fix the kind of observed ions, by providing a vacuum heating gas evacuation means in an ionizing section to clean up a sample gas feed system and the ionizing section to exactly determine the spectral intensity of an analyzed sample. CONSTITUTION:An ionizing section 2 is provided with a gas evacuation pipe 14 and a gas evacuation means 15. A heater 16 is provided for a gas introduction pipe 8, the ionizing section 2 and the gas evacuation pipe 14. A contaminative substance such as a solid or gaseous impurity which is clinging to or adsorbed in the walls of the pipe 8 and the ionizing section 2 is removed by vacuum heating gas evacuation for cleaning. As a result, cluster ions of the contaminative substance other than a measured sample are not generated in cluster ions produced in the ionizing section 2. An exact spectrum of the analyzed sample is thus obtained to accurately fix the kind of observed ions.

摘要： PURPOSE:To stably produce constant spectrum and spectral intensity and improve the analytic accuracy of a mass spectrometer by using a pressure gauge to measure the gas pressure of the medium pressure part and controlling the rate of evacuating gas from the medium pressure part to maintain constant pressure within the medium pressure part. CONSTITUTION:A gas pressure gauge 12 is installed in a medium pressure part which is connected to an ionization part 2 through a thin hole 5 and to which a turbine molecular pump 13 is attached. After the medium pressure part 3 is subjected to primary evacuation 10 by the use of the turbine molecular part 2, the pressure of the medium pressure part 3 is detected. The rate of evacuation by the molecular pump 13 is controlled by feeding the output voltage of a gas pressure gauge circuit 14 back to the rotor speed control circuit of a power supply 15 for driving the molecular pump 13. Since the evacuation rate of the molecular pump 13 is proportional to the speed of the rotor, the evacuation rate can be maintained constant by controlling the speed of the rotor. Therefore, the pressure of the medium pressure part 3 can be adjusted to an optimum level for collisional excitation and dissociation of cluster ions. Furthermore, the evacuation rate of the molecular pump 13 can be maintained constant to maintain constant pressure within the medium pressure part 3.

摘要： PURPOSE:To stably produce constant spectrum and spectral intensity and improve the analytic accuracy of a mass spectrometer by using a pressure gauge to measure the gas pressure inside the medium pressure part and controlling the flow rate of the sample gas in ithe ionization part to maintain constant pressure within the medium pressure part. CONSTITUTION:A gas flow rate control device 14 is installed in a gas introduction tube path 13 for supplying a sample 12 contained in the carrier gas into an ionization part 1. A gas pressure gauge 15 is installed in a medium pressure part 2 which is connected to the ionization part 1 through a thin hole 4. When the temperature is maintained constant, the variation in the internal pressure of the ionization part 1 depends upon the flow rate of the sample gas. Therefore, the flow rate of the sample gas is controlled by using a proportional control circuit 18 to compare the pressure of the medium pressure part 2 with the output voltage of a gas pressure control circuit 18 and then controlling a control valve 19 to make the result of the comparison zero.

摘要： PURPOSE:To enhance the productivity by externally applying thermal, elastic vibrations along the crystal precipitated surface when a seed crystal is brought into contact with a melted raw material, cooling a boundary to precipitate a crystal. CONSTITUTION:A bonding sample of a Ge seed crystal 42 and a GaAs-Ge eutectic unit 43 (15 mol% of GaAs) sealed in a quartz vacuum ampule 47 is thermally melted in an electric furnace 41 having a temperature gradient, and cooled from one end. At this time, an optical pulse is emitted through an optical chopper 45 from the side to apply a periodic temperature vibration to the unit 42. Then, a laminar crystal parallel to the seed crystal 43 is obtained. Thus, after a laminar structure is obtained, a crystal layer is grown with the laminar end as a seed. A temperature periodic vibration is so applied as to coincide in the period of high and low temperatures at the layer period formed initially.

摘要： PURPOSE:To obtain rotary introduction of high airtightness, by disposing input/ output ends at a wave generator, giving the rotation of the wave generator of an input side for a circular spline, then giving the rotation of the circular spline for the wave generator of an output side with accelerating. CONSTITUTION:A thin and elastic flex spline 1 is held airtightly, a wave generator 6 is mounted to the inner side thereof, and the spline is transformed elliptically from its inner circumference. At the outer circumference of the flex spline 1, teeth 2 of (n) number are provided, and a circular spline 7 which has inner circumferential teeth being more then (n) by a plural number is engaged therewith. On the other hand, the wave generator is also mounted to a flex spline 9 which is connected with the spline 1, and the teeth of the circular spline 7 are provided more then the (n') number teeth of the outer circumference of the flex spline 9 by a plural number so as to be engaged mutually. Therefore, the rotation of the generator of an input side is decelerated by the spline 7, and the rotation is accelerated again and transmitted to an output side.

摘要： PURPOSE:To form a uniform crystal by cooling the crystal without imparting vibration thereto, in a heating furnace provided with a specimen heating part and an insulating part, by moving a part of the furnace at the cooling time of the specimen to promote the heat dissipation of the specimen. CONSTITUTION:A furnace heat insulating part 18 is moved to hold a capsule 14 having a specimen received therein by a heat insulating arm 17 and closely adhered to a furnace fixing part 15. When the heating/cooling furnace reaches space and gravity is lost, a current flows to a heater 16 and especially an eutectic crystal part is heated to be allowed to reach the m.p. thereof. A current is controlled to hold temp. slightly higher than the m.p. and, when the eutectic crystal is sufficiently diffused and becomes uniform, the heater 16 is cut off and two furnace heat insulating parts 18 are immediately sufficiently moved left and right. Because the furnace heat insulating parts 18 disappears from the circumference, the temp. of the eutectic crystal is lowered and, when reaching the m.p., the crystallization of the eutectic crystal starts from the interface of a seed crystal and the eutectic crystal to grow the eutectic crystal.

摘要： PURPOSE:To obtain an accurate and stable optical system, by equalizing a distance from the center of a beam splitter up to a reflecting surface of a fixed mirror reflecting a reference beam of light and a distance from the center of the beam splitter to a reflecting surface of a travelling mirror. CONSTITUTION:In a positioning carriage, a fixed mirror is so arranged that a distance from a beam splitter 13 up to a travelling mirror located at the center of travelling stroke through a plane mirror 20 and a distance from a beam splitter to a fixed mirror are so set as to be equally b+l+S/2. In this case when a temperature change DELTAt is observed, the greatest reading is obtained from the equation II, giving the maximum error of (S/2).alpha.DELTAt. As comparison of this value with that obtained by the conventional optical system I gives an answer of l>alpha, the error given by the present invention is clearly smaller. Thus, by comparison of the optical system related to the present invention and a state provided with a static pneumatic bearing type travelling guide, a stage available for positioning in submicron order can be manufactured.
