Title: Magneto-optical disc and recording/reproducing method therefor
Inventor: TOKITA TOSHIAKI
IPC: G11B11/105
Filed: 1994-05-24
Abstract: PURPOSE:To enhance the recording capacity drastically in multiple-recording by employing two recording layers and specifying the relationship of Kerr's rotational angle and ellipticity between the two layers. CONSTITUTION:A dielectric layer 2, two recording layers 3, 4, and a protective layer 5 are laminated sequentially on a transparent substrate 1. Assuming the Kerr's rotational angles and ellipticities of the recording layers 3, 4 are thetak1>thetak2, xsi2, they are set to satisfy the relationships thetak1>thetak2, and xsi1<xsi2. Recording is effected by irradiating the magneto-optical disc with a light of relatively high power on one recording layer (e.g. the layer 3) and with a light of low power on the other recording layer 4. A signal recorded on one recording layer 3 is reproduced by irradiating the recording layer 3 with a linearly polarized light and detecting the reflected light whereas a signal recorded on the other recording layer 4 is reproduced by irradiating the recording layer with a circularly polarized light and detecting the reflected light.

Filed: 1981-08-26
Abstract: PURPOSE:To obtain an optical fiber whose refractive index is not lowered at the central part by forming a quartz glass film contg. boron oxide on the inner wall of a round and hollow glass tube, evacuating the tube, and heating it from the outside to make the tube solid in an elliptical shape. CONSTITUTION:Quartz glass 2 contg. about 5% boron oxide is deposited on the inner wall of a quartz glass tube 1 having a round hollow part by a chemical vapor deposition method. The internal pressure of the tube 1 is made about 10mm.H2O lower than the external pressure, and the tube 1 is heated to about 1,900 deg.C. The boron oxide of high volatility in the innermost layer of the tube 1 is volatilized and scattered to form a thin layer of pure quartz, and by making the tube 1 solid in a flat shape, an elliptical pure quartz part 5 is formed at the central part. Thus, the refractive index distribution is not lowered at the core part 5, and a polarization retaining optical fiber with a small loss is obtd. by drawing.

Title: Dynamic pressure type plain bearing and manuracture thereof
Inventor: FURUMURA KYOSABURO
IPC: F16C17/02
Filed: 1987-05-29
Abstract: PURPOSE:To improve the accuracy of the inner diameter size and shape of the bearing in the caption by fixing a thin inner cylindrical body made of thermohardened resin to the inner surface of a metallic outer cylindrical body through a fixing means at the molding. CONSTITUTION:In a bearing 10, an inner cylindrical body 15 which is made of a thermohardened resin molded in a mold tool is fixed to a metallic outer cylindrical body 11 through fixing means such as grooves 12, 13. The volume contraction of the inner cylindrical body 15 is not rendered any contraction therefore toward the side of inner diameter face when molding material therefor is hardened but toward the side of the outer cylindrical body 11 to reduce the wall thickness. As a result, the thickness of the inner cylindrical body 15 becomes thin to be about 0.2-2mm, and the molding material is hardened uniformly when the inner cylindrical body 15 is molded, resulting in the reduc tion of the amount of the contraction. Accordingly dispersion in the inner diame ter sizes of the bearing 10 is eliminated so that the accuracy of shape is also improved.

Title: Magnetic recording and reproducing device
Inventor: NAKANIWA KOUICHI
IPC: G11B5/027
Filed: 1983-07-22
Abstract: PURPOSE:To decrease the number of the stages of electric adjustments in a process of manufacture by correcting the high frequency band of a reproduced signal through an equalizer amplifier behind the head amplifier of a magnetic head without providing the inductance of the magnetic head nor a resonance capacitor forming a resonance circuit to a head amplifier input stage. CONSTITUTION:When an amplifier having a flat output is constituted, the reproduction output of the head has such characteristics that the reproduction output decreases more and more as the frequency becomes higher and higher owing to various losses, so frequency characteristics after amplification are as shown by a dotted line 18. When demodulation is performed in said state, an upper and a lower side-band wave become unbalanced and inversion is caused. Consequently, the overall waveform has a peak at 4MHz, and an FM equalizer amplifier part 11 attains such peaking as to obtain a waveform 19 of left-right symmetry about said peak and performs phase compensation so that the phase is flat over the entire frequency range, thus constituting the head amplifier circuit which has excellent characteristics without a variable capacitor nor a variable resistor for Q adjustment which are necessary conventionally.

Abstract: PURPOSE:To exactly determine the carbon in a metal by subjecting a hard brazing filler metal to a heating treatment in a 200-400 deg.C range in a gaseous atmosphere contg. oxygen. CONSTITUTION:The org. binder in the brazing filler metal burns to form carbon dioxide and water which flow through a dust removing section 20 and a desulfurizing section 20A by which an exhaust gas 22 is obtd. This heating treatment is executed in the 200-400 deg.C range to change the carbon in the metal to the carbon dioxide. The prescribed amt. of the carbon dioxide is introduced by a branch valve 21 and a constant rate suction pump 23A into an electrolytic cell 23. A barium salt soln. is filled in the cell 23 and the pH is migrated to an acidic side by absorption of the carbon dioxide. This pH change is detected by a pH detecting amplifier section 25 of a measuring section 24 and an alkali is generated in the cell 23 by electrolysis in such a manner that the prescribed pH value is restored. The generated amt. of the alkali is proportional to the Coulomb quantity flowing the electrolytic cell. The Coulomb quantity can be set in proportion to the number of pulses by a gate circuit 27 and a pulse generator 26 and the total Coulomb quantity is instructed on a counter circuit 28.

Abstract: PURPOSE: To make it possible to use an electrooptic material as a thin layer and to conduct light waves in the layer by leaving the electrooptically active region in a light transmission layer as an open state and arranging prescribed electrodes in the regions made to remain. CONSTITUTION: The non-irradiated strip type regions 2, 1 of polymers which have perpendicular boundary surfaces A and B and are held polarizable by the selective irradiation from above utilizing the aid of a mask are left in the open state in the light transmission layer 2. Next, two pieces of the strip type electrodes 6 and 7 made of, for example, aluminum, are mounted at a buffer layer 3 and at least relative counter edges 6.1 and 7.1 among these electrodes run parallel. The voltage which induce non-uniform electric fields is impressed between the electrodes 6 and 7 via contacts 8 and 9 by the layers 2 and 3. The polarization of the regions 2, 1 of the polarizable polymers left in the open state are preferably locally induced by using the electrodes 6 and 7 mounted after the selection irradiation of the layer 2.  As a result, the e/o (electrooptic) regions 2, 1 are better composed from the regions having the max. electric flux density. The assurance of good e/o inductive action is made possible.
