Abstract: This invention provides a process for producing a vinylated nucleic acid in an efficient and cost-effective manner through the implementation of vinylation of an amino-containing nucleic acid with a vinylating agent. This invention also provides a process for producing a vinylated nucleic acid in an efficient and cost-effective manner by a method in which PCR is carried out in the presence of an amino-modified nucleotide and dNTP and a vinyl group is introduced into the resulting PCR amplification product or by a method in which PCR is carried out in the presence of a vinyl-modified nucleotide and cNTP.

Abstract: A managing computer adds a bulk-sales negotiation ID to a bulk-sales negotiation to distinguish the bulk sales negotiation from a normal sales negotiation. An amount of scheduled shipment and completed shipment for the bulk sales negotiation is managed by a bulk-sales-negotiation managing unit based on the bulk-sales negotiation ID. The managing computer obtains an amount of completed shipment of a regular negotiation by subtracting an amount of completed shipment of the bulk-sales negotiation from a total amount of completed shipment. The managing computer calculates a seasonal index based on an amount of completed shipment according to a stratification of products to design a sales plan. The managing computer adds an amount of schedule shipments of the bulk sales negotiation to the sales plan.

Abstract: An optical network unit of each consumer is connected to an optical line terminator of a network operator through a subscriber line formed of an optical fiber. When a particular consumer desires to download digital content from a content retailer to the particular consumer through a network of the network operator, the particular consumer requests a bandwidth reservation of a resource reservation server of the network operator, so that a transmission condition composed of a bandwidth and a time zone is reserved in cases where the downloading of the digital content at the transmission condition is possible. Thereafter, the bandwidth reservation is sent to a downward bandwidth managing unit, and the digital content is downloaded from the content retailer to the particular consumer through the network of the network operator at the transmission condition according to the bandwidth reservation under control of the downward bandwidth managing unit.

Abstract: In cases where a consumer desires to receive digital content from a digital content retailer through a network, information designating the digital content and a digital content transmission condition such as a transfer rate and a transmission time-zone are sent to the digital content retailer through the network. The digital content retailer reserves the transfer rate and the transmission time-zone in the network and downloads the digital content to the consumer through the network at the digital content transmission condition according to the reservation. After the downloading of the digital content is completed, the consumer pays a charge for the digital content itself and a transmission charge corresponding to the digital content transmission condition to a credit company, the credit company pays the charges to the digital content retailer, and the digital content retailer pays the transmission charge to a network operator managing the network.

Abstract: A probe is utilized in the hybridization with a natural nucleic acid to form a double strand. The probe contains a cytosine derivative which specifically binds to guanine by forming two hydrogen bonds with the guanine nucleotide and/or a guanine derivative which specifically binds to cytosine by forming two hydrogen bonds with the cytosine nucleotide. This enables a large number of hybridization reactions to be carried out at once under uniform conditions.

Abstract: An administrator contracts with an advertiser and a holder holding a right to let a third person use digital content. The holder sets the digital content to become usable by using an execution key, downloads the execution key to the administrator through a network, and downloads the digital content not made usable to a distributor through the network. The distributor downloads the digital content to a user through the network. When the user sends an execution declaration of the digital content to the administrator, the administrator downloads the execution key and an advertising information piece received from the advertiser to the user through the network. Therefore, the user can use the digital content made usable by the execution key while seeing the advertising information piece.

Abstract: A dry turbo vacuum pump has a multistage circumferential impeller supported on a shaft, and a stator which cooperates with it to form a multistage peripheral flow pump. A centrifugal pump arranged at an inlet side of the peripheral flow pump is also mounted on the same shaft, so that gas sucked from the inlet is discharged to the atmosphere from the peripheral flow pump. The multistage peripheral flow pump and at least one stage of the centrifugal pump are integrated.

Abstract: A magnetic head device has a magnetic head slider by means of which information is recorded in and read from a magnetic recording medium. The magnetic head slider is supported by a supporting structure having an internal cavity, an opening formed in a portion of the structure where the magnetic head slider faces the magnetic recording medium and communicating with the internal cavity, and a gas passage through which the gas introduced into the internal cavity through the opening is discharged to the exterior of the internal cavity. With this arrangement, the pressure acting on the back surface of the magnetic head slider is adjusted to keep the slider afloat, while removing dust suspended in the gas around the recording medium and the supporting structure.

Abstract: A compressor has stationary and orbiting scroll members formed thereon with spiral wraps engaged with each other to define compression chambers which, when the orbiting scroll member is moved relative to the stationary scroll member, are radially inwardly moved while decreasing their volumes. Each scroll member is composed of a metallic base scroll member having a spiral wrap formed on one side and a coating layer of a resin compound formed on the said side of the scroll member, including the surfaces of the wrap. The coating layer is molded by placing the base scroll member in a mold cavity with a space left between the said side of the base scroll member and a mold part and by injecting the resin compound into the space.

Thus a great electromagnetic force is generated, and at the same time a high propulsive force is obtained with the magnetic flux density not reduced in the gap accomodating one phase of coils alone.

Abstract: A sealed scroll compressor comprises a scroll compressor section, an electric motor, a sealed container, an oil storage, a fixed and orbiting scroll members, and a wire mesh member for improvement of oil separation in refrigerant gas. A shell portion of said sealed container is lined annularly with the wire mesh member and the gas containing oil is adapted to flow downwardly along the wire mesh member.
