摘要： A recording medium for magnetic field modulation recording by which the recording can be done with the weakest possible demodulating field. On a transparent substrate (11), a first dielectric layer (12), a recording layer (13), a recording auxiliary layer (14), a second dielectric layer, and a reflecting layer (16) are formed. The recording layer is made of a transition metal-rare earth metal amorphous alloy, and usually has a thickness of hundreds Angstroms. The recording auxiliary layer (14) is also made of a transition metal-rare earth metal amorphous alloy, but its Curie temperature Tc2 is 10K higher than the Curie temperature Tc1 of the recording layer (13). The layer (14) is as thin as 70 Angstroms or less. The aspect ratio of the recording auxiliary layer (14) is 0.7 or more at the Curie temperature Tc1 of the recording layer (13). These required characteristics of the recording auxiliary layer (14) can be materialized by adjusting the composition of the recording auxiliary layer (14) and reducing its density. As another materials for the recording auxiliary layer (14), a transition metal such as Fe, Co, a non-magnetic metal such as Pt, Al, Ti, Cr, or a nitride of transition metal-rare earth metal amorphous alloy. This medium is particularly suitable for a small-sized magneto-optic disc.

摘要： A magnetooptical recording medium comprises a transparent substrate (10), on which are sequentially laminated a protective film (14); a first magnetic film (11) made of a light rare earth metal, heavy rare earth metal, and transition metal alloy; a second magnetic film (12) made of a light rare earth metal, heavy rare earth metal, and transition metal alloy; a third magnetic film (13) made of a light rare earth metal, heavy rare earth metal, and transition metal alloy; a protective film (15); and a reflecting film (16). The sandwich of the first, second and third magnetic layers constitutes a recording film (17). The compositions of the first and third magnetic layers contain a large amount of light rare earth metal and have a large Kerr rotational angle in a single wavelength region (400 nm to 700 nm). On the other hand, the composition of the second magnetic layer contains a large amount of heavy rare earth metal and has a property suitable for vertical magnetization. The recording film (17) consisting of the sandwich of the first, second and third magnetic layers has a large Kerr rotational angle as a whole in a short wavelength region, and has a large coercive force. This recording film (17) is sufficiently thin (below 400 Å). When the three-layered sandwich and the reflecting layer (16) are combined with each other, a further greater Kerr rotational angle can be obtained.

摘要： The object of the invention is to realize large-capacity recording based on the multilayer recording. The magnetooptic recording medium consists of multilayered vertically magnetizing films, capable of storing information even in layers other than the first layer which is closest to a source of light. The layers have higher Curie temperatures, as they are more distant from the source of light. In the magnetooptic reproducing method using the above recording medium, the information stored in a magnetic domain pattern of a layer is transferred to a layer closer to the source of light. To record information in the medium, external magnetic field is applied so that information is written successively from the layer having highest Curie temperature.

摘要： A PD (81) is positioned at a predetermined position on an optical table, the rotation of a resist master (110) is stopped, a focusing laser (73) is driven, and a head (77) is positioned in a proper position by a head slider control circuit (101). The master (110) is turned, a focusing servo circuit (103) is started and, the PD (81) is moved horizontally by a focus fine adjustment circuit (99) by a minute distance corresponding to an estimated adequate focus position data. Since the difference between voltage signals from the two output terminals of the PD (81) is varied because of the surface vibration and minute movement caused by the rotation of the master (110), a differential amplifier (103a) moves a recording lens (77a) vertically by a distance of several microns so as to make an error signal zero. Numerical information on a digital display (93) at this time is compared with the focus position data. When both of them agree with each other, the focus position data is employed as an adequate focus position data and used for the initial setting of the adequate focus position. When they do not agree with each other, the numerical information is employed as the adequate focus position data and the focus position data is rewritten. By using the numerical adequate focus position data, the inital setting of the adequate focus position matching the type of the resist master can be carried out easily.

摘要： An inexpensive small-sized PLL (phase-locked loop) oscillator for use as the clock source of a computer, etc., which can output such a high frequency about 40 MHz that is difficult to obtain from a fundamental-based crystal oscillator. The oscillator operates as stably as the fundamental-based crystal oscillator does, is easy to set a frequency, can be produced in a short lead time, and can be easily handled like the conventional crystal oscillator. The PLL oscillator is housed in a package, which contains a piezoelectric vibrator, an oscillation circuit for driving the vibrator, and a PLL circuit which receives a reference signal from the oscillation circuit. The output frequency of the PLL oscillator is determined by the oscillation frequency of the oscillation circuit and the scaling factor of the programmable divider of the PLL circuit so that a prescribed output frequency can be obtained by selecting the corresponding scaling factor, which may be stored in a programmable read-only memory.

摘要： A piezoelectric vibrator so assembled that a space may be formed between a vibrating piece and a plug, with a conductive resin-made connection layer being formed for connecting, to the vibrating piece, a slab-like lead which has its top end opened in a U-shaped form. The top end of the lead can absorb shock due to its elasticity. Before forming the connection layer, a temporary fastening layer is formed between the top end of the lead and the vibrating piece using UV curing resin, or silver paste is applied to either the top end or the vibrating piece to increase the workability. By this method, piezoelectric vibrator units, which have a high resistance to shock and have a little change in frequency when being left in a high temperature environment and which are very reliable, can be mass-produced at low cost.

摘要： A power supply device for rectifying or blocking reverse current of power from an internal generator provided in a portable electronic equipment, such as, fit electronic equipment to be worn around the arm, by using a unidirectional unit including a diode, a by-pass switch connected in parallel with the diode, and a controller for turning on the by-pass switch when a forward voltage is generated in the diode, thus substantially eliminating the loss accompanied by the forward voltage at the time of power supply. Since the electromotive voltage of the generator which can be internally provided in the above type of electronic equipment ranges from a level substantially the same as the forward voltage to approximately several times the forward voltage, the rectification efficiency may be significantly improved by using the unidirectional unit.
