  • Publication number: 20100207929
    Abstract: A booster circuit has: a charge pump configured to perform a booster operation that boosts a voltage supplied from an external power source and outputs the boosted voltage as an output voltage through an output capacitor; and a feedback circuit section configured to control the booster operation depending on the output voltage. A mode of the booster operation includes: a charge mode that charges the output capacitor with the voltage supplied from the external power source; and a discharge mode that discharges the output capacitor. The mode of the booster operation is switched between the charge mode and the discharge mode depending on the output voltage. The feedback circuit section has a booster operation control section that secures a period during which the mode is not switched between the charge mode and the discharge mode in accordance with an external synchronizing signal.

  • Publication number: 20100150308
    Abstract: An X-ray inspection apparatus includes an X-ray radiating part, an X-ray detecting part, a mass estimation unit and a mass class determination unit. The X-ray radiating part is configured and arranged to radiate X-rays to an inspection target. The X-ray detecting part is configured and arranged to detect the X-rays radiated from the X-ray radiating part that transmitted through the inspection target. The mass estimation unit is configured to estimate a mass of the inspection target based on an amount of the X-rays detected by the X-ray detecting part. The mass class determination unit is configured to determine which mass class among a plurality of mass classes within a preset range the inspection target belongs to based on the mass of the inspection target estimated by the mass estimation unit.

  • Patent number: 7719602
    Abstract: An electronic device can perform photographing by an AF (Auto-Focusing) function and a PF (Pan-Focus) function, and can give improvement of quickness of the taking of an image by automatically selecting an image, which is taken into the device, from a relation between the AF function and a shutter operation. The electronic device has an imaging part which catches an image obtained through an optical system, and also has a focusing mechanism which moves the optical system to an auto-focusing position or a fixed focus position. The electronic device further comprises a switch and a control part. The switch functions as a focusing switch ordering the focusing mechanism a focusing action, and also functions as a shutter switch ordering taking of an image caught by the imaging part. By this, the switch orders the focusing action or the taking of the caught image.
