  • Patent number: 6460095
    Abstract: A data transfer apparatus and a data transfer system intended to transfer data continuously input or output to/from a main memory without any interruption and to transfer continuous data on a general-purpose bus such as a PCI bus, and a recording medium storing a program that commands a computer to execute all or some of functions of each component of the data transfer apparatus or the data transfer system.

  • Publication number: 20020037278
    Abstract: This invention provides methods of forming new blood vessels in diseased or damaged tissue in a subject, methods of increasing blood flow to diseased or damaged tissue in a subject, and methods of increasing angiogenesis in diseased tissue in a subject, which methods comprise: a) isolating autologous bone marrow-mononuclear cells from the subject; and b) transplanting locally into the diseased or damaged tissue an effective amount of the autologous bone-marrow mononuclear cells, thereby forming new blood vessels in the diseased or damaged tissue. The new blood vessels may be capillaries or collateral vessels in ischemic tissue or any site of angiogenesis. Also provided are methods of treating tissue in disease or injury by local transplantation with an effective amount of the autologous bone marrow-mononuclear cells so as to induce vascularization in such diseased tissue.

  • Patent number: 5414568
    Abstract: A variable speed digital signal reproducing apparatus, particularly related to low speed reproduction of a digital signals recorded in a recording medium. The apparatus includes a unit for determining whether a reproduction PCM signal is renewed or not. Based on the renewal determination, PCM data of one frame is stored in a memory and the PCM data is read at a frequency rate corresponding to a tape reproducing speed at that time. Furthermore an interpolating device operates on the read PCM data to produce a PCM signal having the same frequency with which the PCM signal was read from the memory means.

  • Patent number: 5146448
    Abstract: This invention relates to a time code recording and reproducing apparatus for recording and reproducing time codes corresponding to a digital signal. Time code converting means (100) converts a first time code into a second time code. A frame phase which occurs during the recording of input information is determined by frame timing generating means. A phase difference between a frame of the second time code and a recording frame is detected by phase difference detecting means (103). Phase difference correcting means (104) outputs a third time code on the basis of the detected phase difference. The input information is recorded together with the third time code. Thereby, the recording can be performed while the relation of the correspondence between the input information and the time code is held. In addition, the reproduction can be performed.

  • Patent number: 4243839
    Abstract: A transducer such as used for an electro-dynamic loudspeaker adapted to convert an electric signal into a mechanical motion or, a moving coil type velocity sensor adapted to convert a mechanical motion into an electric signal. The so-called "Bl force factor," representative of the product of the magnetic flux density B and the length l of the main coil, is so controlled as to be made constant, whereby the linearity of the transducer is improved.

  • Patent number: 4015089
    Abstract: A multi-way speaker system comprising a tweeter, a squawker and a woofer wherein each of the speakers is arranged in staggered relation along their radiating axis at a predetermined spacing from each other and provided with an appropriate crossover network coupled to an input terminal of each of the speaker whereby sound pressure-frequency characteristics of a synthesized sound wave resulting from the synthesis of respective sound waves radiated from respective speakers are rendered flat, and phase frequency characteristics of said synthesized sound wave are rendered linear, over an entire band to improve a waveform transmission characteristic of an overall speaker system.
