  • Patent number: 8069278
    Abstract: A server is installed with host bus adapters (HBAs). The HBA causes light-emitting components thereon to emit light in abnormal light emission patterns upon falling into an abnormal condition, and in predetermined light emission patterns upon receiving a predetermined command. A method for managing the HBA includes storing abnormal light emission patterns of the HBA, detecting an abnormality as to whether a predetermined HBA is in an abnormal condition, obtaining current light emission patterns of a light-emitting component of an abnormal HBA which is detected to be in the abnormal condition in the detecting, and controlling light emission by sending the predetermined command to all of the HBAs except the abnormal one to cause the light-emitting components thereof to emit light in the predetermined light emission patterns, when the current light emission patterns, obtained in the obtaining, do not match the abnormal light emission patterns stored in the storing.

  • Patent number: 6489866
    Abstract: In a microwave module including a transmitting portion circuit and a receiving portion circuit, the transmitting portion circuit and the receiving portion circuit are respectively constructed by transmission lines of different kinds in which polarization planes are orthogonal to each other, and are constructed on the same surface of the same substrate. For example, one of the transmitting portion circuit and the receiving portion circuit is constructed by a microstrip line, and the other is constructed by a coplanar line. Further, one of the transmitting portion circuit and the receiving portion circuit is constructed by a microstrip line, and the other is constructed by a slot line. By this, there is obtained a microwave module in which mutual interference by an electromagnetic field between element circuits in the module can be suppressed, the circuits can be arranged close to each other without requiring a shielding member, and miniaturization of the module can be realized.

  • Patent number: 6339362
    Abstract: By connecting a grounding conductor pattern directly to a grounding terminal of a field-effect transistor and connecting a series circuit comprising a stabilized resistor and an open-circuit stub having a length equal to quarter of a parallel resonance frequency, undesirable parallel resonance caused by the grounding conductor pattern and the open-circuit stub is suppressed, and a voltage drop in the stabilized resistor is suppressed when a bias voltage is applied to the field-effect transistor. Accordingly, the operation of a microwave amplifier is stabilized.

  • Patent number: 6310517
    Abstract: A microwave amplifier (10) of the present invention contains such an arrangement that both an inductor (12) and a resistor (13) are loaded in a parallel manner between a source electrode of a field-effect transistor (11) and the ground. Since the inductor (12) has a stray capacitance component (B), the inductor (12) is resonated at a resonant frequency “f0”. However, since the source electrode of the field-effect transistor (11) is grounded via a resistor (13) connected in parallel to the inductor (12), even when the inductor (12) is opened due to a resonant operation, the field-effect transistor (11) is operated under normal condition. As a result, the operation of the microwave amplifier (10) is stabilized.
