An inner disc portion and an outer disc portion are connected through first to fifth connecting ribs. The second and third connecting ribs which are provided on the outer diameter side are inclined reversely to each other so that a portion where the distance between outer-diameter-side end portions of the second and third connecting ribs is wider and a portion where the distance is narrower are provided alternately. The fourth connecting ribs are provided in the portions where the distance is wider respectively. In addition, each of the fifth connecting ribs are provided between the first connecting ribs and the second and third connecting ribs respectively. The inclination angle &thgr; of the second and third connecting ribs is regulated so that the distances between the end portions of the respective ribs are equal to one another.

Method for producing a magnetooptical recording medium

A magnetooptical recording medium is provided with a transparent substrate, a first magnetic layer, a second magnetic layer having a higher Curie point and a lower coercive force than those of the first magnetic layer and being exchange coupled with the first magnetic layer. The medium further includes a third magnetic layer located between the first and second magnetic layers, so that the first magnetic layer is closer to the transparent substrate than the second and third magnetic layers and the third magnetic layer is closer to the transparent substrate than the second magnetic layer. Also disclosed is a process for recording on such a medium.

A magneto-optical recording method employs a magneto-optical recording medium having a first magnetic layer which exhibits a low coercive force at room temperature and a high Curie temperature and a second magnetic layer which is exchange-coupled to the first magnetic layer and which exhibits a higher coercive force and a lower Curie temperature as compared with those of the first magnetic layer. A magnetic field modulated in accordance with information to be recorded is applied to the magneto-optical recording medium while irradiating it with a light beam of a constant intensity so as to record the information. The recorded information is simultaneously confirmed by using a reflected light of this light beam.

A switching power source applicable to an electronic apparatus and capable of stabilizing an output voltage with a high transform efficiency even when an input voltage varies over a broad range. The output voltage is controlled at the primary circuit side of the power source. The base current is maintained constant with no regard to the input voltage.

In a watt-hour meter in which first and second input signals representing an analog electric current and an analog voltage of an alternating current are converted into first and second digital signals, a first adder produces a sum signal which represents a sum of the first input signal and an additional analog signal of a frequency different from that of the first input signal and which is substituted for the first input signal. The meter may further comprise a second adder which adds another additional analog signal to the second input signal. Alternatively, the meter comprises low-pass filters and oversample-and-convert circuits to produce the first and the second input digital signals.
