  • Publication number: 20060198168
    Abstract: A control method for controlling a switching power supply circuit has a control circuit including a setting device that limits the exciting current of a transformer at the time of changeover from a switching delay to a switching period. The setting value set by the setting device is changed slowly to prevent the exciting current of transformer from changing rapidly and to reduce the excitation noise of transformer, and the setting value is changed gradually to prevent the output voltage from lowering even when the load becomes heavier than a certain value during the light load operation. The control method facilitates reducing the electric power consumption of the switching power supply circuit under a light load, reducing the transformer excitation noise and preventing the output voltage from lowering when the load is light.

  • Publication number: 20050286221
    Abstract: In this invention, the CPU of a NAS board, which is liable to become hot, is cooled by concentrating a larger amount of air onto a heat sink. A plurality of logic circuit boards 3 are mounted on a control section 1D of a disc array device 1. The circuit component 4A for realizing the NAS function, liable to become hot, is provided with a heat sink 5. The aperture of the main air inlet section (Wb) is covered with a top plate 8. Airflow guidance sections (Wa, Wc) are respectively provided on both sides of the main air inlet section. Since the fin pitch of the airflow guidance sections is set narrow, the air inflow resistance (airflow resistance) of these is higher than that of the main air inlet section. Due to this difference in airflow resistance, the air in the vicinity of the airflow guidance sections is guided into the main air inlet section. The top plate 8 prevents outflow of air that has flowed into the main air inlet section to outside the heat sink 5.

  • Patent number: 6927980
    Abstract: A disk drive box 10 accommodates a plurality of disk drives 20 within a case 11. A side face of each of the drives 20 is provided with a heat-absorbing part 40 including a heat pipe, corresponding to heat producing area HP. The heat taken away by the heat-absorbing part 40 is transmitted to a heat sink 50 of the rear of a backboard 30 via a heat connector 60. The heat sink 50 is cooled by cooling air flowing through an air duct 7. By cooling the drive 20 with the heat pipe, clearances between the drives 20 can be substantially eliminated, and it is made unnecessary to form an opening for air cooling in the backboard 30. Thus, size reduction is possible, and it is possible to increase the degree of freedom for a wiring pattern formed on the backboard 30.

  • Publication number: 20050165675
    Abstract: To prevent skimming of card data used in electronic payment, attention is given to a phenomenon occurring in performing the fraudulent act of attaching a skimmer to a settlement terminal—namely that the settlement terminal is turned on and off several times. Detected power-on/off abnormalities are determined in accordance with an abnormal power-on/off definition stored in a memory. This may, for example, be that when the number of times the settlement terminal is turned on or off within a specified time period exceeds a predetermined number, the power-on/off is defined as abnormal power-on/off. When the power-on/off is determined to be abnormal, warning information is sent to a settlement organ computer.

  • Publication number: 20020154575
    Abstract: When a stem switch (8) is pulled out, a switch signal forming unit 9 outputs a signal (RS) indicating that effect, a control unit (13) receives the signal (RS) and starts clocking by a timer (13a). The control unit (13) receives a signal (HS) output from an electricity-generation detecting unit (12) within the clocking period, detects the electricity generating operation of an electricity generating unit (10), and outputs a signal (CS) indicating that effect. A narrow pulse forming unit (7) forms a narrow pulse having a width of such a degree that the motor (5) is not driven based on the signal (CS), and outputs the narrow pulse to a motor driving circuit (4). The motor driving circuit (4) flows a fine current through a coil (4a) which drives the motor (5) based on the narrow pulse. An external device detects a variation of the narrow pulse, thereby confirming whether electricity is generated.

  • Patent number: 6459657
    Abstract: A time information repeating installation in a radio clock system, which receives advance notice information, distinguishes advance notice content by detecting means 9, sets a transmission start time by addition setting means 10 in accordance with the content, sets an additional period by change period setting means 11, and stores the content into transmission start time storage means 12. When the stored time agrees with the time of a main counter 8, transmission starts. Therefore, even when a sudden time change occurs, the repeating installation can perform transmission at the reception timing of a subsidiary device. The subsidiary device can effectively update time data for summer or daylight savings time.
