Title: Method for recording magneto-optical recording medium
Inventor: TAKAKUWA ATSUSHI
IPC: G11B11/10
Filed: 1991-04-09
Abstract: PURPOSE:To lessen the erasing remainder by recording with an emitting laser power in which the incomplete erasure when the emitting laser power at the time of recording is decreased more than the first recorded power by the prescribed value becomes the prescribed value or below for the first signal. CONSTITUTION:A magnetic head 202 performs the translation to a disk 201 rotated by a spindle 207 together with an optical head 204 by a voice coil motor 206 through a power communication arm 205. While a laser beam 203 irradiates from the optical head 204, by adding from the opposite side of a magnetic field disk 21 with the magnetic head 202, a magnetic domain is formed and the information is recorded or erased. The incomplete erasure when the emitting laser power at the time of recording is decreased by 10% becomes -40dB or below for the signal, a crosstalk is -26dB or below, and as such, recording is performed by the emitting laser power.

Title: Diffusion joining method
Inventor: OOSUMI MAKOTO
IPC: B23K20/00
Filed: 1982-05-10
Abstract: PURPOSE:To eliminate the defective contact between objects to be joined and to join said objects uniformly by pressing top and bottom dies while interposing a member softer than the parts to be joined between the top or bottom die and the objects to be welded so that the objects to be joined are diffusion-joined to each other. CONSTITUTION:Objects 3, 4 to be joined are disposed between a top die 1 and a bottom die 2 which are respectively rigid materials. A metallic pad 5 which is a member softer than the objects 3, 4 is interposed between, for example, the die 1 and the object 3. The objects are diffusion-joined in this state under application of pressing force P relatively on both dies 1, 2. Mild steel or copper is usable if the objects 3, 4 are, for example, a Ti-6Al-4V alloy (900-950 deg.C diffusion joining temp.). The objects are joined uniformly by the above-mentioned method; in addition, the manufacturing tolerance of the dies and the influence on the accuracy of a press are decreased; therefore, the cost of jigs and tools and the equipment cost for working are reduced.

Title: Method for correcting aberration of hologram and its optical system
IPC: G03H1/04
Filed: 1992-03-31
Abstract: PURPOSE:To improve the diffraction efficiency over the entire area of a hologram without generating an astigmatism by previously applying the astigmatism for correcting aberrations so as to form an point image at the time of reproduction on an object light side. CONSTITUTION:A hologram sensitive material 1 consisting of a photopolymer, etc., is irradiated with reference light 2 and object light 3 parallel therewith. Bluish green lasers of about 441 to 528nm which can sensitize the photopolymer are used for the respective light beams 2, 3. The astigmatism of the object light 3 by the wavelength difference from the reproduced light is previously calculated and the diversion points of the object light (meridian) 3 and the object light (spherical segment) 4 are held apart by as much as the previously calculated aberration component. The method of applying such aberration is attained by using a cylindrical lens 5 and applying the astigmatism with the meridian plane and the spherical segment plane. The hologram image having the aberration with the meridian plane and the spherical segment plane is recorded on the hologram sensitive material 1 in such a manner. The image in which the aberrations of the object light beams 3, 4 are offset by the astigmatism based on the wavelength difference between the reference light an the reproduced light is obtd. when the reproduced light conjugate with the reference light 2 is made incident perpendicularly on the hologram sensitive material 1 at the time of reproduction.
