  • Patent number: 8951795
    Abstract: The present invention relates to a method of safely and simply inducing differentiation of mononuclear cells into cells that promote neovascular stabilization and maturation, and lead to recovering from ischemia or tissue repair. The cells according to the present invention are obtained by inducing differentiation of a mononuclear cell by culturing the mononuclear cell in a medium (particularly a serum-free medium) containing one or more selected from vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), thrombopoietin (TPO), granulocyte-colony stimulating factor (G-CSF) and FMS-like tyrosine kinase 3 ligand (FLT3L), and collecting a cell population expressing CD11b.

  • Patent number: 5202980
    Abstract: In an information processing system comprising a plurality of processor units each of which comprises a memory unit, an execution processor, an information transfer unit, and a bus line connected to one another, the memory unit has a control information area and a data area for storing a control information signal and a main data signal, respectively, and a saving area for saving the main data signal which is stored as a copied signal of the data signal. When the copied signal is saved into the saving area, an information transfer unit receives, through the bus line, the main data signal which is read out of the memory unit and which is transferred to the other processor unit. An additional data signal is produced by the other processor unit and stored through the information transfer unit into the saving area.

  • Patent number: 5171383
    Abstract: A catheter guide wire is provided for guiding a catheter into a body cavity such as a blood vessel. The base material constituting the wire is made of an elastic alloy wire and subjected to a heat treatment such that its flexibility is sequentially increased from its proximal to distal end portions. A thermoplastic resin or/and a coil spring can be applied to at least the distal end portion of the wire base material. A method of manufacturing the catheter guide wire is also provided. The method is characterized in that the leading end side of the base material is divided into a plurality of areas and subjected to a heat treatment by changing the heat treatment temperature and the time conditions in units of the areas so that the flexibility of the base material is sequentially increased from the proximal to distal end portions of the leading end side.

  • Patent number: 5086361
    Abstract: A rotary head drum for a video tape recorder includes a stationary lower drum member having a base portion and inner and outer cylindrical portions extending generally upwardly from the base portion to define an internal cavity therebetween. A rotary assembly is rotatably mounted on a rotor shaft coaxial with the lower drum member and has at least one rotary magnetic head mounted thereto for recording digital signals on and reproducing the signals from a magnetic tape wrapped about the drum. A motor for driving the rotary heads, a rotation detector or tach generator for detecting the rotation of the motor, and a multi-channel rotary transformer for transferring digital signals to and from the rotary head are all housed in the cylindrical internal cavity surrounded by the base portion, and inner and outer cylindrical portions of the lower drum member which thereby reduces the overall axial height of the video tape recorder.
