Title: Driving circuit of laser light emitting element for optical disk and optical disk device using it
Inventor: KIMURA MOTOI
IPC: G11B7/125
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To realize simultaneously high density recording and high S/N reproduction. SOLUTION: A laser is driven by high power at the time of recording, and a laser is driven by low power at the time of reproducing to prevent changing a recording film state. As light emission is unstable and mode hopping occurs in a laser driven by low power, pseudo multi-mode light emission can be realized by superimposing a high frequency wave on a driving current.  A laser is driven by a pulse train at the time of recording to make a recording region appropriate, but as a high frequency wave component is included in the pulse train and overshoot and ringing occurs in a laser driving waveform by parasitic inductance Lp of a wiring to a laser element LD and a recording error is caused, svana circuit 20 is inserted and electromotive force in the parasitic inductance is absorbed, the device is controlled so that the svana circuit 20 is separated from the driving circuit at the time of reproducing to prevent that also a high frequency wave superimposed at the time of reproducing is suppressed by the svana circuit 20.

Title: Electron beam linear vapor deposition device
Inventor: MANFUREETO NOIMAN
IPC: H01J37/30
Filed: 1986-05-20
Abstract: PURPOSE:To permit vapor deposition to a broad and uniform layer thickness by irradiating an electron beam which is passed through a horizontal magnetic field and a vertical and variable magnetic field so as to be parallel deflected to a longitudinally long evaporator crucible having magnetic traps. CONSTITUTION:This electron beam linear vapor deposition device irradiates the electron beam 1 emitted from an electron gun 2 having a dynamical electron beam deflecting part after passing the beam through the horizontal magnetic field in the spaces 3 between magnetic pole pieces 4 to deflect the beam to a longitudinally long crucible 5 and suppresses the electron current by the magnetic traps consisting of the horizontal magnetic field 7 formed by the 2nd magnetic pole pieces 6 to prevent the temp. elevation of a material for vapor deposition. The perpendicular magnetic field 8 which is variable with local places and time is formed by providing horizontal magnetic piece plates 9, 10 within the spaces 3 of the above-mentioned vapor deposition device as well as a yoke 11 and excitation coil 12 connected thereto. The above- mentioned electron beam 1 having about 60-90 deg. angle beta is thereby deflected to the specified angle alpha by the cooperation of the above-mentioned magnetic fields 7, 8. A straight deflecting line 13 is thus formed in the above-crucible 5 and the vapor deposition material is broadly and uniformly deposited on the material for vapor deposition.

Title: Method for conveying and/or melt-kneading powder
Inventor: NISHIGORI TAKUYA
IPC: B29B7/94
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce adherence of powder to a screw spiral groove or conveying member by incorporating oil in material powder. SOLUTION: Oil is added to powder by directly mixing or internally adding it into the powder. To raise density as it is conveyed by a screw, the screw is disposed in a powder supplying position so that a ridge of the spiral groove the one screw is not brought into contact with a trough of the groove of the other screw. And, the trough of the groove is made shallow as the conveyance is advanced, pressure is applied to the powder to raise an effect of kneading. And, as the conveyance of the powder is advanced, it is softened and kneaded while raising its temperature. And, an embracing member for the screw is heated and set so that its temperature is low at a powder supplying position and becomes higher as the conveyance is advanced. As oil, polydimethyl siloxane is used.  Thus, when the powder is treated by a screw feeder or screw type kneader, adherence and solidification of the powder to the unit and the like can be prevented.
