A system and method for scheduling jobs in a multiprocessor machine is disclosed. The status of resources, including CPUs on node boards and associated shared memory in the multiprocessor machine is periodically determined. The status can indicate the resources available to execute jobs. This information is accumulated by the topology-monitoring unit and provided to the topology library. The topology library also receives a candidate host list from the scheduling unit which lists all of the resources available to execute the job being scheduled based on non-trivial scheduling. The topology library unit then uses this to generate a free map F indicative of the interconnection of the resources available to execute the job. The topology monitoring unit then matches the jobs to the resources available to execute the jobs, based on resource requirements including shape requirements indicative of interconnections of resources required to execute the job. The topology monitoring unit dispatches the job to the portion of the free map F which match the shape requirements of the job. If the topology library unit determines that no resources are available to execute the job, the topology library unit will return the job to the scheduling unit and the scheduling unit which will wait until the resources become available. The free map F may include resources which have been suspended or reserved in previous scheduling cycles, provided the job to be scheduled satisfies the predetermined criteria for execution of the job on the suspended, have a lower priority, or are reserved resources.

An LCD driver starts reading a digital image signal of one frame from a VRAM in response to a reproduction timing signal. A driving timing signal generator generates a driving timing signal in response to a synchronizing signal, whose phase is shifted by a delay time from the reproduction timing signal. So a phase difference corresponding to the delay time is provided between the driving timing signal and the reproduction timing signal. Synchronously with the driving timing signal, an image sensor is driven to shoot a subject and output an analog image signal of one frame. After being converted into a digital form, the image signal is written in the VRAM sequentially from the first line of one frame. The phase difference is determined so that the LCD driver starts reading the image signal sequentially from the first line, immediately after the first line is written in the VRAM.

An image pickup apparatus is provided, which comprises a plurality of image pickup areas formed on a same semiconductor chip and arranged in the horizontal and the vertical directions, each image pickup area having a plurality of pixels arranged in the horizontal and the vertical directions, a plurality of vertical scanning circuits which sequentially scan pixels in the vertical direction to scan a plurality of image pickup areas in the vertical direction independently from each other, a plurality of lenses, at least one of which is provided in each of the plurality of image pickup areas and which focuses light to form an image on the image pickup areas, and a driving circuit which drives the plurality of vertical scanning circuits so that at least a part of a scanning period of each of the plurality of vertical scanning circuits overlaps with each other.

There is provided a radiographic imaging device including: a radiation detector having plural sensor portions; a receiving unit that receives request data requesting radiation irradiation permission from a control device that controls a radiation source; a control unit that controls the radiation detector such that an accumulation extraction operation is repeatedly performed that extracts charge that has accumulated in each sensor portions of the radiation detector, the accumulation extraction operation being performed after a specific accumulation period has elapsed that is greater than the irradiation period of radiation; a determination unit that determines whether or not radiation irradiation of the irradiation period from the radiation source is possible within the accumulation period of the accumulation extraction operation; and a permission unit that permits radiation irradiation if the determination unit has determined that irradiation is possible, and otherwise that permits radiographic image after starting the accumulation period of the next accumulation extraction operation.

A thermal activation apparatus has a casing which houses a drawing roller that draws a heat-sensitive adhesive sheet through an insertion port and transports the sheet through the casing. A cutter unit cuts the sheet to a predetermined length, a thermal activation unit thermally activates a heat-sensitive adhesive layer of the cut sheet, and a discharge roller discharges the thermally-activated sheet through a discharge port. A CPU controls the cutter unit and the thermal activation unit based on various factors so that the heat-sensitive adhesive layer is thermally activated only when needed.

A camera includes a focus adjusting system; first and second switches for a focus adjusting system and an exposure device; and a controller. If the second switch is operated before the focusing lens group reaches a specified focal length position, the search operation stops and the exposure device activates after the focus adjusting system performs the search operation until an infinite focus position. If the second switch is operated after the focusing lens group reaches the specified focal length position, the search operation immediately stops and the exposure device activates. If the in-focus position is detected by the search operation after completion thereof, the focusing lens group moves to the in-focus position and the exposure device activates. If no in-focus position is detected by the search operation after completion thereof, the focusing lens group moves to the specified focal length position and the exposure device activates.
