    摘要: A process for purification which permits satisfactory removal of impurities from a block copolymer consisting essentially of polyethylene glycols and poly(acidic amino acid) and is suitable for the production of a polymeric carrier having a pharmaceutically acceptable purity; a process for producing such a polymeric carrier; a block copolymer reduced in impurity content; a polymeric carrier as described above; pharmaceutical preparations in polymeric form, produced by the use of the carrier; and a method of subjecting polyethylene glycols and poly(acidic amino acids)—which are impurities contained in the block copolymer—to treatment with either an ion-exchange resin or a partition/absorption resin and then determining the quantities of them with a gel filtration column.

    摘要: A carrying apparatus for carrying an automobile dash module to an interior of a vehicle includes a support portion, a sliding part, and a fixing part. The support portion is configured and adapted to carry the dash module into the interior of the vehicle through a door opening of a vehicle body. The support portion includes a main frame that extends in a direction that is substantially parallel to a direction of a length of the dash module supported by the support portion. The sliding part is slidably coupled to the main frame to slide in the longitudinal direction of the main frame. The fixing part is configured and adapted to be fixed to a predetermined portion of a periphery of the door opening. The fixing part is coupled to the sliding part and configured to engage a portion of the vehicle body so that the main frame and said sliding part can pivot about an axis oriented in a vertical direction relative to the vehicle body. With the carrying apparatus of the present invention, it is easy to carry a dash module having various components surrounding a dash into the interior of a vehicle, even after doors are attached to the vehicle body.

    摘要: A filter has a plurality of resonators formed regularly on a substrate and made of a superconducting material. In measuring resonance frequency of the resonators, the filter and a conductive metal plate having an opening are placed in a vacuum chamber so that all the resonators other than one resonator which faces the opening are covered with the metal plate. The metal plate has an input probe and an output probe at the opening of the metal plate. The resonance frequency of each resonator is measured in sequence while rotating the metal plate. Each resonator is adjusted in shape by a laser trimming or providing a dielectric film in correspondence with the measured resonance frequency so that all the resonators have a fixed resonance frequency.
