摘要： An optical disk apparatus includes a semiconductor laser for emitting a light beam, and an automatic power control or APC circuit for driving the laser. A compound prism structure is optically coupled to the laser in an optical head section, and defines a first optical path for causing a front laser light to be projected onto a rotating optical disk and guiding a reflected light therefrom toward a first photodetector, and a second optical path for guiding a part of the reflected light toward a second photodetector. An output signal of the first photodetector is used to generate a reproduced information signal. An output signal of the second photodetector is fed back to the APC circuit as a front light monitor signal. A part of a laser control signal internally generated in the APC circuit is supplied through a wiring line to a noise reduction circuit as a laser noise monitor signal. The noise reduction circuit subtracts this noise monitor signal from the reproduced information signal to provide a noise-suppressed information signal.

摘要： In an A/D converter in which a first comparator A/D converter for providing the most significant bits of a digital output and a second comparator A/D converter for providing the least significant bits of the digital output are cascaded, a switching circuit is provided between the first A/D converter and the second A/D converter. This switching circuit is responsive to the comparison between an analog input voltage and first comparison reference voltages in the first A/D converter to apply two adjacent first reference voltages between which the analog input voltages lies to both ends of a voltage dividing circuit network of the second A/D converter to thereby provide second comparison reference voltages. In the second A/D converter, the second comparison reference voltages are compared with the analog input voltage by comparators, to provide the least significant bits of a digital output.

摘要： A semiconductor chip including at least three variable capacity diodes for use at a frequency of 30 to 300 megaherzs is mounted on a grounding member so as to be sealed within a package. A plurality of external connection conductors each coupled to the diode and a plurality of external ground conductors coupled to the grounding member extend out of the package. Each ground conductor is disposed between the adjacent two of the external ground conductors. The arrangement permits a decrease of interference occurring due to a stray capacitance between the diodes.

摘要： Target fluid is made into electrolyte solution when measured fluid-quality value is lower than a first condition value, by substituting an impurity anion contained in the target fluid with a predetermined anion and substituting an impurity cation contained in the target fluid with a predetermined cation, and purified when the fluid-quality value is higher than a second condition value. The above procedures are repeated, so that the fluid-quality value of the target fluid falls within a predetermined range, to make the target fluid into electrolyte solution with a correlation between pH and conductivity.

摘要： A thin-film crystal wafer having a pn junction includes a first crystal layer of p GaAs, a second crystal layer of n InxAlyGa1−x−yP, the first and second crystal layers being lattice-matched layers that form a heterojunction, and a control layer of a thin-film of InxAlyGa1−x−yP differing in composition from the n InxAlyGa1−x−yP of the second crystal layer is formed at the interface of the heterojunction. The control layer enables the energy discontinuity at the interface of the InxAlyGa1−x−yP/GaAs heterojunction to be set within a relatively broad range of values and thus enables the current amplification factor and the offset voltage to be matched to specification values by varying the energy band gap at the heterojunction.
