  • Patent number: 11135075
    Abstract: To provide a bioabsorbable stent including: a first tubular unit containing a plurality of cells coupled to each other, each of the cells formed from substantially linear parts and a substantially circular arc part and having a substantially U shape which opens to one end in the axial direction of the stent; and a second tubular unit having the same shape as that of the first tubular unit, the second tubular unit containing a plurality of cells each of which has a substantially U shape which opens to a direction opposite to the opening direction of the opposing first cell. The first tubular unit and the second tubular unit are alternately arranged in sequence to surround a central axis of the stent. Coupling members couple substantially linear parts in some of the opposing cells in the respective neighboring tubular units.

  • Patent number: 8437228
    Abstract: A thermally assisted magnetic recording head with highly efficient optical coupling, while guiding a laser beam from a semiconductor laser element, i.e., a light source, to a leading end thereof, eliminating an influence due to heat generated by the element, and having excellent floating characteristics. The thermally assisted magnetic recording head includes a substrate 2 having a first optical waveguide 1, a semiconductor laser element 100, and a slider 4 having a second optical waveguide 3 formed on an end surface. The semiconductor laser element 100 is fixed on the substrate 2 so that light emitted from the element 100 propagates through the first optical waveguide 1 and a slider 4 is fixed on the substrate 2 so that light emitted from the first optical waveguide 1 propagates through the second optical waveguide 3. High optical coupling efficiency is then achieved, while ensuring both heat-dissipating and floating characteristics.

  • Publication number: 20100234385
    Abstract: It is thought that applications and use of tetrahydrobiopterin (BH4), which is used as a pharmaceutical, will expand due to its superior efficacy. However, in addition to BH4 being extremely expensive, since it is unstable with respect to oxidation, applications other than pharmaceuticals are considered to be difficult. Further, it is difficult for BH4 to permeate through a blood-brain barrier, so that BH4 concentrations in the brain tend not to increase under the present conditions. Biopterins are oxidized form of BH4, stable to oxidation, easy to handle, and can be produced inexpensively. The inventors found that administration of biopterin can be expected to demonstrate effects equal to or greater than those of administration of BH4.

  • Publication number: 20090104668
    Abstract: Biopterins are useful compounds utilized in pharmaceutical agents or functional foods. The presence of sepiapterin reductase (SPR) involved in the biosynthesis of biopterins has not been confirmed so far in microorganisms except for a few microorganisms such as blue-green algae. For efficiently producing biopterins using microorganisms, it has been demanded to obtain and use SPR genes derived from microorganisms. The present inventors have found that when Saccharomyces cerevisiae or Escherichia coli is transformed with a YIR035C gene from Saccharomyces cerevisiae or a yueD gene from Bacillus subtilis, the transformed microorganism secretes biopterins into a culture solution. Based on this finding, the present invention provides a polypeptide, DNA encoding the polypeptide, a recombinant vector comprising the DNA, and a transformant obtained by transformation with the vector, which are useful in biopterin production using microorganisms.

  • Patent number: 7445793
    Abstract: The present invention provides a scaffold in which cells can be stably retained and grafted in a uniform distribution state in the culture, preferable proliferation ability and viability can be secured, and particularly in the case of cartilage, fixation treatment such as suture can be carried out in the transplantation into affected parts after the culture, and the mechanical strength is provided sustainable for (weighted) compression at the initial stage of transplantation. The present invention relates to a 3-dimensional porous scaffold for tissue regeneration which comprises a structure composed of vertically long-shaped pores having a pore diameter of not less than 10 ?m to not more than 500 ?m and pore length of not less than 20 ?m to not more than 1 cm being juxtaposedly arranged obtained by a production process comprising rapid freeze-drying as a key technology.

  • Publication number: 20070062454
    Abstract: A substrate support assembly and method for dechucking a substrate is provided. In one embodiment, a support assembly includes a substrate support having a support surface, a first set of lift pins and one or more other lift pins movably disposed through the substrate support. The first set of lift pins and the one or more lift pins project from the support surface when the pins are in an actuated position. When in the actuated position, the first set of lift pins project a longer distance from the support surface than the one or more other lift pins. In another aspect of the invention, a method for dechucking a substrate from a substrate support is provided. In one embodiment, the method includes the steps of projecting a first set of lift pins a first distance above a surface of a substrate support, and projecting a second set of lift pins a second distance above the surface of the substrate support that is less than the first distance.

  • Patent number: 5294781
    Abstract: A moving course data collection system for use in a large-scale store such as a supermarket or the like in which a portable scanner is provided to customers which allows customers to input article code data for articles in the store customers wish to purchase. The display location of all articles in the store is stored. Thus, every time a customer inputs article code data, the time and an approximation of the customer's position in the store is determined from the article code data input by the customer and the display location of that article in the store. This information is sequentially recorded, thereby collecting data on the customer's moving course through the store.
