摘要:
A parallel processing system includes a plurality of computers accessibly connected through a network, and distributedly executing a plurality of processes. Each of the plurality of computers is composed of an operation processing unit configured to execute an allocated process, a local memory group having a first area and a second area and an I/O control circuit. The operation processing unit executes the allocated process by using the first area as an access destination in a first period and, and executes the allocated process by using the second area as the access destination in a second period subsequent to the first period. The I/O control circuit is composed of an updating section configured to update data stored in the local memory group to the latest data by carrying out communication among the computers. The updating section updates the data stored in the first area in the second period.

摘要:
A technique which can reduce a cost of a space machine installed with a solar cell. The space machine is composed of a light collecting unit and the solar cell. The light collecting unit is arranged on a surface of the body of the space machine to collect incident sun light inside the body. The solar cell is installed inside the body to receive the sun light collected by the light collecting unit.
摘要:
An infrared detector including a reflection portion which transmits far- and middle-infrared rays and which reflects near-infrared and visible rays; a photo-current generating portion having a plurality of layered quantum dot structures in each of which electrons are excited by the far- and middle-infrared rays having passed through the reflection portion so as to generate photo-current; a light emitting portion having a plurality of layered quantum well structures into each of which electrons of the photo-current generated by the photo-current generating portion are injected and in each of which the electrons thus injected thereinto are recombined with holes so as to emit near-infrared and visible rays; and a photo-detecting portion which detects the near -infrared and visible rays emitted from the light emitting portion and which detects the near-infrared and visible rays emitted from the light emitting portion and then reflected by the reflection portion.

摘要:
An infrared detector which converts entering infrared IR into light in a different wavelength band, and which detects the converted light in the different wavelength band includes: a convex-concave structure provided on a light acceptance surface of the infrared detector; and a metal film provided on an outer circumferential face of the light detector other than the light acceptance surface thereof, the metal film covering the outer circumferential face. In the infrared detector, light which enters the light detector after passing through the convex-concave structure and the converted light in the different wavelength band are confined inside the light detector: by causing the entering light to be reflected on the metal film; by causing light reflected on the metal film to be reflected on the convex-concave structure; and by causing the converted light in the different wavelength band to be reflected between the metal film and the convex-concave structure.
