  • Patent number: 8030618
    Abstract: A pellet 4 for use in spectrometry includes a first powder 41 of a light transmitting material in a compression-molded form, and a second powder 42 which is hydrophilic and water-insoluble and is dispersedly mixed in the first powder. A sample 40 to be subjected to spectrometry is e.g. in a powdery form and dispersedly mixed in the first and the second powders 41 and 42. When the sample 40 is a hydrate, the second powder 42 exerts the effect of accelerating dehydration of the sample 40, so that stable spectrum data on the sample in the dehydrated state is obtained early. This makes it possible to perform a processing such as identification of the sample 40 early and precisely.

  • Patent number: 7849235
    Abstract: In response to a request from a central processing unit (CPU) 11 (i.e., firmware) of a node 10, a transfer control unit 14a of a direct memory access (DMA) controller 14 transmits a message and data to another discretionary node 3 by way of a serial bus 1, a switch 2 or the like. In this event, the firmware stores data to be transmitted, a message, and a descriptor thereof in memory 12. In the case of requesting the transmission of the message, the descriptor contains a flag indicating “whether or not there is a need to wait for a response from the data transmission destination”. If the flag is set to ON, the transfer control unit 14a notifies the firmware of a simulated completion immediately instead of waiting for a completion response from the transmission destination node 3.

  • Patent number: 7774513
    Abstract: A DMA circuit operates a plurality of DMA channels in parallel, enabling reduction of the circuit scale and fewer development processes. A channel manager circuit reads in sequence the control information for each DMA channel from control memory, performs analysis, and according to the divided DMA control sequence, performs state processing (DMA control). Further, the channel manager circuit updates the control information, writes back the control information to the control memory, and executes time-division control of the plurality of DMA channels. Hence the circuit scale can be reduced, contributing to decreased costs, and the number of development processes can be reduced.
