  • Patent number: 10575903
    Abstract: A treatment device is disclosed for treatment of a living body lumen. The treatment device can include an optical fiber having an emitting part that emits laser light from a side circumferential surface. Two or more grooves are provided in the emitting part at places different in a longitudinal direction of the emitting part. The two or more grooves have two or more kinds of shapes and intensities of the laser light emitted from the grooves adjacent to each other are different. A maximum region of intensity of the laser light emitted from the emitting part is located on one end side relative to a center position in the longitudinal direction of the emitting part. The intensity of the laser light emitted from the emitting part on the other end side of the emitting part relative to a position of the maximum region decreases toward the other end side.

  • Patent number: 7638083
    Abstract: A molding method which includes charging a resin composition in molten state containing not less than 7 wt % to less than 30 wt % of a fibrous fiber (A) and more than 70 wt % to not exceeding 93 wt % of a resin (B) into a die for shaping purpose when a temperature of the die is in the range of [the Vicat softening point minus 20° C.] of resin (B) to less than a melting point thereof, when resin (B) is crystalline resin, or when a temperature of the die is in the range of [the Vicat softening point minus 20° C.] to [the Vicat softening point plus 20° C.] of the resin (B), when resin (B) is non-crystalline resin, cooling the die after shaping to temperature which allows taking-out of a molded product.

  • Patent number: 6759003
    Abstract: Blow-molding molds 10 and 20 having parison shutters 31 and 32 for preventing an inflation of the parison 3 toward the outside of the molds 10 and 20 are used in a blow-molding method of the present invention. In other words, a closed space for preventing the parison 3 from inflating out of the molds 10 and 20 are formed by the parison shutters 31 and 32 and a predetermined air is secured in the parison 3 in a frame clamping step (B). In the subsequent mold clamping step (C), the pressure inside the parison 3 starts to be increased when the molds 10 and 20 press the parison 3, so that the parison 3 can be continuously in contact with the die design surface 11. Accordingly, since the parison 3 can be uniformly contracted by cooling, molding failure such as streaks and uneven pattern transfer can be avoided, thus obtaining a blow-molded product having good appearance.

  • Patent number: 6303071
    Abstract: Provided is a method for producing blow moldings having a relatively large size through blow molding by use of a simple facility. The method including the steps of feeding a melt parison of crystalline resin into the space between molds, clamping the molds, blowing a pressurized fluid into the interior of the parison so as to cause the parison to be into close contact with the inner surfaces of the molds and to solidify the parison, wherein, while the parison and the mold inner surfaces are in close contact, the temperature of inner surfaces of the molds is maintained at a temperature from a temperature 10° C. lower than the crystallization temperature of the crystalline resin to the melting point of the resin, and the parison is removed from the molds after the parison is cooled through introduction thereinto or discharge therefrom, during or after blowing-in of the pressurized fluid, of a cooling medium not higher than room temperature.

  • Patent number: 5788297
    Abstract: A resin-made shock absorbing member for a vehicle used as a bumper bean of the vehicle and the like and the method for producing the same. The resin-made shock absorbing member for the vehicle is structured to include an elongated curved portion (20) having a hollow portion, and an attachment portion (30) for fixing to a vehicle body (11) to be united and thus continuously formed with the curved portion (20) at both ends in the longitudinal direction of the curved portion (20). By structuring the attachment portions (30) to have a hollow portion and a solid portion, at least extending in the longitudinal direction of the curved portion (20), attachment work can be carried out from the outer side of the vehicle, and the shock absorbing function can be ensured along the whole length of the member (10).

  • Patent number: 5714227
    Abstract: Tubular parison of a molten resin to such an extent as to melt undergoes a pre-blow with a blow molding apparatus, whereupon the blown tubular parison is clamped between dies of a blow molding apparatus, and also, is mutually weld together with parts of the inside faces of the tubular parison to form a multiple of isolated hollows in the parison. Gas is fed through a multiple of gas feed nozzles which are provided in the die into the hollow portions. A number of the hollow portions are opened in a second process to form a functional part.

  • Patent number: 5527581
    Abstract: The car interior member and its molding method are offered to improve recycling and to reduce the number of parts. The instrument panel 10 as the car interior member is made by molding integrally the core member 11 organizing the main structure of certain area of car interior and the functional member 12, 13, 14 having particular function and attached to the core member 11 by the blow molding. On the occasion of then, the number of parts can be more reduced when the base layer arranging the most inside and the foamed layer and the surface layer arranging outside of the base layer are effected by the multilayer blow molding in case of the instrument panel 10 formed with the multi-layer construction.
