IPC: C22B9/00
Filed: 1987-04-08
Abstract: PURPOSE:To produce high-purity Al by heating and melting raw Al in gaseous H2 flow of an extremely low O2 concn. to remove impurities therefrom, then moving a molten area where the raw material is partly melted successively to concentrate impurities at one of the above-mentioned Al. CONSTITUTION:Gaseous H2 having the extremely low O2 concn. as low as <=1ppm is introduced through an inlet 5 into a quartz reaction tube 3 and is discharged from an outlet 6. The raw material Al 1 is imposed on a boat 2 and is housed into this reaction tube 3. The raw material Al 1 is heated to the temp. above the m.p. thereby by a reaction furnace 4 in the above-mentioned gaseous H2 flow and is held for the prescribed time at said temp. so that the gases, oxides, etc., contained therein are removed. The temp. of the furnace 4 is thereafter once lowered down to the m.p. of the Al or below. A zone melting furnace 7 is then energized to partly melt the Al 1 and to form the molten area 8. The furnace 7 is then gradually moved in an arrow direction from the right end to the left end of the boat 2 to move the area 8 successively. The residual impurities in the Al 1 are thereby swept and concentrated to one end thereof by a segregation effect, by which the purity of the Al 1 is increased.

Title: Optical recording method
Inventor: TSUJIOKA TSUYOSHI
IPC: G11B7/30
Filed: 1993-04-14
Abstract: PURPOSE:To obtain an optical recording method by which recording can be efficiently performed with high sensitivity by using an optical recording medium having a prescribed reflectivity at the wavelength of recording light and setting the reflectivity after irradiation and the reflectivity before and after recording at prescribed values. CONSTITUTION:The method uses an optical recording medium in which a recording layer 2, reflecting film 3, and protective film 4 are successively formed on a substrate 1 and which reacts in such a photon mode that the reflectivity R2 before irradiation against the wavelength of recording light is <=0.5. The reflectivity RH of a recording mark section after irradiation is made higher than 0.5 by irradiating the medium with recording light so as to cause a color distinguishing reaction and, at the same time, the reflectivity RL before recording and reflectivity RH after recording are set so that they can satisfy a relation 0.5-RL- -RH-0.5. Therefore, an optical recording method by which recording can be performed on a photon mode type optical recording medium with high sensitivity can be obtained. In addition, it is desirable to respectively set the reflectivity RL before recording and reflectivity RH after recording at 0.2<=RL<0.5 and 0.5<RH<=0.8.

The necessary calorific value correcting part 10 is a device indicating boiling up capacity (calorific value) of the next day, and if the appointed day is one having the bathing at the time of a bathing pattern of ''not bathing on the next day of bathing'', the part 10 instructs an operating part 11 so that the heating up capacity for the next day becomes small. A control part 12 receives operational result from the operating part 11 and electrification to a heater 5 is controlled.

Furthermore, the resistor R0 is detached and capacitance between the wiring conductors 11 and 12 is measured with an impedance analyzer or the like, thereby showing graphically a relationship between the crosstalk and the capacitance in advance. Then, capacitance between the wires of a printed circuit board as an inspection object is measured, and resulting capacitance is collated with the graph for evaluating a crosstalk.
