  • Patent number: 8611087
    Abstract: To cool a blade type server disposed in an air-conditioned room, the following arrangements are made. The first is at least one shell having a ventilation passage disposed in the air-conditioned room. The second is, the following are disposed in a ventilation passage: racks, in which blade type servers each composed of a case with slim boards housed therein are stacked; cooling coils each having a coolant passage and a cooling fin and cooling a passing air; and at least one fan unit having axial-flow fans placed therein and producing air currents in one direction. The third is the fan unit forces a cooling air to flow in one direction in the ventilation passage thereby to cool the servers in the racks. The cooling coils and racks are disposed alternately so that warmed cooling air after passing through the rack is cooled by the cooling coil and then cools the next rack.

  • Patent number: 7071166
    Abstract: The present invention provides healing promoters for skin wounds such as rupture, abrasion, surgical incision, skin ulcer and burn. Coexistence of Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH2 (SEQ ID NO: 1) or Phe-Gly-Leu-Met-NH2 (SEQ ID NO: 2) with insulin-like growth factor-I exhibits a remarkable promotive action on healing the skin wounds. Accordingly, combined administration of at least one of the substance P analogs and pharmaceutically acceptable salts thereof with the insulin-like growth factor exhibits a promotive effect on epidermal extension and a promotive effect on healing the skin wounds.

  • Patent number: 6833358
    Abstract: The object of the present invention is to find new effects of natriuretic peptides in an ophthalmological field. The present invention provides eyedrops for promoting lacrimal secretion or for treating keratoconjunctival disorders containing the natriuretic peptide as active ingredient. The natriuretic peptides are atrial natriuretic peptides (ANP), brain natriuretic peptides (BNP) and C-type natriuretic peptides (CNP). Typical examples of the keratoconjunctival disorder are dry eye, corneal erosion and corneal ulcer.

  • Patent number: 6809916
    Abstract: A shock absorbing body is interposed between an internal component such as a hard disk drive (HDD) and the inside surface of an enclosure for an electronic apparatus such as a notebook personal computer. The shock absorbing body includes a first receiving surface defined at one end of the shock absorbing body so as to receive the internal component. A second receiving surface is defined at the other end of the shock absorbing body so as to receive the inside surface of the enclosure. A constriction is formed in the shock absorbing body between the first and second receiving surfaces. When a larger impact is applied to the enclosure, the shock absorbing body is allowed to suffer from a fracture at the constriction. The energy of the impact is transformed into the energy of the fracture at the constriction. The impact energy is sufficiently consumed in this manner. The internal component can be protected from the larger impact.

  • Publication number: 20040166934
    Abstract: An object interaction expression apparatus for expressing interactions between plural objects that move by simulation in a virtual space is provided. The apparatus includes an expression mode storing unit, an interaction magnitude calculating unit and an expression controller. The expression mode storing unit stores in a correlated form an interaction magnitude of an object and a corresponding expression mode in which the interaction magnitude will be expressed. The interaction magnitude calculating unit calculates interaction magnitudes of objects that interact with each other. The expression controller controls an expression of the interaction magnitude of the objects that interact with each other based on the expression modes stored corresponding to the interaction magnitude calculated.
