    摘要: An optical disc comprises a resin disc substrate, a recording medium layer formed on the disc substrate, a high purity of transparent layer, and a transparent protective resin layer. The transparency of the transparent layer is larger than that of the transparent protective resin layer. A laser beam is focused on the recording medium layer through the transparent protective layer and the transparent layer. The transparent layer is a transparent adhesive layer or an air layer. The focused laser beam is not affected by foreign matter in the vicinity of the recording medium layer due to the high transparency of the transparent layer on the recording medium layer.

    摘要: A flow restrictor includes a housing having a chamber defined therein which is divided into two pressure chambers by means of a partition wall. An umbrella-shaped one-way check valve, for permitting or blocking fluidic communication between the two pressure chambers, and an orifice for restricting the fluidic communication between the two chambers, are coaxially arranged on the partition wall so as to decrease the size of the flow restrictor.
