  • Patent number: 8344328
    Abstract: A position detector includes a photodetector having photodetecting elements; and a scintillator crystal having uniaxial optical anisotropy. The scintillator crystal is continuous in a uniaxial direction, is disposed on the photodetector such that the uniaxial direction is not perpendicular to the normal to a photodetecting surface, and has a length at least three times the pitch of the photodetecting elements. The uniaxial anisotropy allows at least 4% of scintillation light emitted from a region farthest above the photodetecting surface to reach the photodetecting elements, and allows from 4% to 35% of scintillation light emitted from a region closest to the photodetecting surface to reach the photodetecting elements.

  • Patent number: 8145927
    Abstract: In a computer room including information processing devices and air conditioners, power saving of the computer room by means of optimization of workload allocation to the information processing devices is achieved in a short time. There, a coefficient of air conditioner performance with respect to the information processing device (device-specific COP) is calculated for each air conditioner. Further, a device-associated power consumption expression representing a total of device power and air conditioner power is created for each information processing device. Also, power consumption of the entire computer room is calculated from the device-associated power consumption expression of the information processing devices. Also, workload allocation is determined by using power saving performance evaluation indexes based on the device-associated power consumption expression of the information processing devices.

  • Patent number: 7986037
    Abstract: As a power feed route in a semiconductor chip, a power feed route which reduces antiresonance impedance in the frequency range of tens of MHz is to be realized thereby to suppress power noise in a semiconductor device. By inserting structures which raise the resistance in the medium frequency band into parts where the resistance is intrinsically high, such as power wiring in a semiconductor package and capacitor interconnecting electrode parts, the antiresonance impedance in the medium frequency band can be effectively reduced while keeping the impedance low at the low frequency.
