  • Publication number: 20120097169
    Abstract: Disclosed is a respiration-assisting tube whereby tissue damages in vivo can be prevented and, as a result, inflammatory reactions and infections can be avoided. The respiration-assisting tube is developed based on the finding that adhesion of cells to a respiration-assisting tube can be inhibited by coating the respiration-assisting tube with a polymer containing 2-methacryloyloxyethyl phosphorylcholine (MPC). Also, the respiration-assisting tube is developed based on the finding that, by coating a respiration-assisting tube with a polymer containing MPC, mucosa peeling and tissue damages, which occur after using the respiration-assisting tube, can be prevented and, as a result, inflammatory reactions can be avoided.

  • Publication number: 20110183000
    Abstract: Disclosed is an artificial bone material having controlled calcium ion elution, which does not induce cytotoxicity or any inflammatory response. It is found that the elution of a calcium ion from an artificial bone material for transplantation which contains a calcium-containing substance can be prevented effectively by subjecting the carrier to a surface treatment or adding a surface-treating agent to the carrier. It is also found that the induction of cytotoxicity can be prevented and the induction of an inflammatory response can also be prevented by using the above-mentioned carrier having controlled calcium ion elution.

  • Publication number: 20110166672
    Abstract: An object of the invention is to provide a bone filling material capable of promoting the bone regeneration effect of a growth factor such as platelet rich plasma (PRP). Inventors of the invention anticipated that the bone filling material adsorbs a growth factor like PRP, and the combined use of the bone filling material with PRP, the bone regeneration effect of PRP might be impaired. Further, the invention is basically related to the inhibition of this adsorbing effect of the bone filling material by using a capping agent. Since the adsorbing effect of the bone filling material is thus inhibited, PRP can exert the bone regeneration effect thereof in the case of using the bone filling material together with PRP.

  • Patent number: 7779172
    Abstract: A DMA controller controls DMA transfer in an information processing system. Input and output devices are a transfer source or a transfer destination in DMA transfer and request DMA transfer. A DMAC activating unit is provided with an event monitoring unit and an event register. The event register registers an event subject to monitoring. The event monitoring unit detects an event generated in the input and output devices and determines whether the detected event matches an event registered in the event register. If it is determined that the events match, the event monitoring unit activates the DMA controller.

  • Patent number: 7684884
    Abstract: There is provided an information processing apparatus in which a CPU and an audio processing unit are coupled by a bus. The audio processing unit includes a ring buffer that temporarily retains audio data, and performs an input/output process of the audio data. An interrupt signal generator generates a buffer empty signal, when the audio data is output from a buffer in the ring buffer and the buffer is empty, decimates the buffer empty signal in accordance with a sampling frequency of audio, and then feeds the interrupt signal that survives the decimation to the CPU. The CPU, upon receiving the buffer empty signal, issues a DMA transfer instruction for writing the audio data into the empty buffer in the ring buffer.

  • Patent number: 7664922
    Abstract: When a concentration of access requests on a specific bank occurs, the delay time is caused due to the competition among the accesses, thereby lowering the processing speed of an information processing apparatus as a whole. A data transfer arbitration unit 172 sequentially transfers data to be recorded to a memory controller 160 that records data in memory having a plurality of banks. A selector 174 selects any DMAC 170 from among a plurality of DMACs, irrespective of priority sequence of transfer service for the DMAC. A transmitter 176 transmits, to a control-side transfer unit 114, data requested to be transferred by the selected DMAC 170. The selector 174 selects consecutively the DMAC 170 so that the transfer service for the same DMAC is consecutively executed, and determines the number of consecutive selections so that a transfer across the banks of the DMAC 170 occurs by a plurality of the transfer services.
