Title: Magneto-optical recording and reproducing device
Inventor: MIYAOKA YASUYUKI
IPC: G11B11/105
Filed: 1991-03-27
Abstract: PURPOSE:To remarkably decreases noise and jitter by efficiently erasing the unstable area of magnetization direction generated with the deterioration of magnetic field intensity at the time of the inversion of modulated magnetic field, and simultaneously, improving the shape of magnetic domain like the feathers of an arrow. CONSTITUTION:Bias magnetic field is supplied on a temperature increasing part by a electric magnet 24 and at the time of switching of the bias magnetic field, the absolute value of the magnetic field intensity decreases. Curie point temperature range is extended to the area where the direction of magnetization is unstable at the time (t2) of rising of the bias magnetic field, even if the bias magnetic field intensity deteriorates, the direction of magnetization is certainly directed to the direction corresponding to the magnetic field polarity. Thus, the unstable area of the magnetic direction is erased since two magnetic domain, one magnetic domain (a) is having the upward direction of the magnetization and another magnetic domain (b) having the downward direction of the magnetization, are formed in recorded pattern and a stable pattern is attained. Also, since the Curie point temperature profile of a perpendicular magnetization film by the irradiation of a laser beam is near a circular shape, the magnetic domain shape like the feathers of the arrow is improved and the recording noise is decreased.

Title: Liquid metal ion source
Inventor: OKU GOJI
IPC: H01J27/26
Filed: 1988-04-06
Abstract: PURPOSE:To protect a heater from the deposition of a sputter atom generated due to an ion beam and stabilize the ion beam of a liquid metal ion source by further enclosing a crucible part coated with a heater film for power supply and heating with a cover. CONSTITUTION:Electric current from a heating power supply 7 flows from a needle shape chip 2 to the terminal of a heater 4 fitted to the center hole 1a' for power supply and heating, and heats the chip 2. Then, the current passes an electrode 11 adjacent to the other end of the other end of the heater 4 and returns to the power supply 7. An ion source metal 5 in a crucible 1 is heated and liquefied. As a result, the metal 5 flows out from the groove 2b of the chip 2, is ionized and taken out as an ion beam 10 via a takeout electrode 3. In this case, the electrode 3 and the like are sputtered, thereby generating a sputter atom and depositing the atom onto the heater 4. Consequently, the resistance of the heater 4 is sometimes reduced and the beam 10 is thereby made unstable. A cover 13, therefore, is provided for the prevention of the deposition of the sputter atom and a stable ion beam can thereby be obtained at all times.

Abstract: PURPOSE:To enable irradiating a light receiving element and thereby measuring a distance, even in case that a reflecting prism which is placed at a close measuring point, is sighted, by deviating a mirror which reflects light of a luminiferous element toward an object lens, against a center of the object lens. CONSTITUTION:Light from a luminiferous element 5 is projected out of an object lens 1 as lights L4 and L5, for instance, via an optical system 4 and a mirror 2. The lights L4 and L5 are reflected by a reflecting prism 11 placed at a close measuring point, as shown L6 and L7 in the figure, to be irradiated in from a lens 1, and the light L7 reaches a light receiving element 10 via a dichroic prism 7 without interference of the mirror 2. Reference light used for distance measurement, is led to the element 10 by the optical system, as a light transmitting signal. The measured distance is obtained from phase difference by distance between the light transmitting signal and a light receiving signal. Each distance is correctly obtained with adjustment by adding correction constant at a computer, and is displayed on a display.
