  • Publication number: 20060041611
    Abstract: A data transfer control system that controls data transfer between a first electronic apparatus connected via a first bus and a device connected via a second bus, including: a management section that conducts a process of receiving a login request when a login request for acquirement of a right to access to the device comes from the first electronic apparatus and that conducts a process of receiving a logout request when a logout request for abandonment of the access right acquired upon receipt of the login request comes from the first electronic apparatus; and a power control section that conducts power control by turning on power supply to the device when the login request to the device comes from the first electronic apparatus.

  • Patent number: 6904022
    Abstract: The objective of the present invention is to provide a data transfer control device, information storage medium, and electronic equipment that can relieve the inconveniences caused whenever a reset that clears node topology information occurs. If a bus reset occurs during a data transfer period in a data transfer control device in accordance with the IEEE 1394 standard, and also the content of ORBs before and after the bus reset is the same, data transfer restarts from a resumption at the point at which the bus reset occurred, thus preventing duplicate printing in a printer. Whenever a bus reset occurs during a data transfer period, the continuation flag is set to on. The first command block ORB comprising a print command that transferred in after the bus reset is used in the comparison with the pre-bus-reset ORB. When no ACK is returned from the initiator because of a bus reset, a transition to a dead state occurs.

  • Publication number: 20040230734
    Abstract: A data transfer control system receives a command packet ORB transferred through a bus BUS 1 (IEEE 1394), issues a command indicated by ORB to a device connected to a bus BUS2 (ATA (IDE)/ATAPI), and orders start of a DMA transfer. The command issued based on ORB is aborted after the completion of the DMA transfer. The data transfer control system compares contents of a command packet ORB1 transferred before a bus reset with contents of a command packet ORB2 transferred after the bus reset. If the contents are different, a command issued based on ORB1 is aborted after completion of a DMA transfer. Dummy data is transferred between the data transfer control system and the device connected to the bus BUS2 until a DMA transfer is completed. Dummy data transfer is controlled by performing a dummy update on a pointer.

  • Publication number: 20040167999
    Abstract: Information that is transferred through a bus BUS 1 (conforming to IEEE 1394) is downloaded into a rewrite area storing device information (such as GUID or config ROM) and data transfer control program information (such as a SBP-2 firmware program), and rewriter processing is performed to write the information into the rewrite area. When it is detected that no device is connected to a bus BUS2 (conforming to ATA/ATAPI or IDE), the rewriter processing starts. The detection of whether or not a device is connected to BUS2 is based on the result of an access to a register of the device. In a download mode, the information is written into the rewrite area by transferring data to and from a PC connected to BUS 1.

  • Publication number: 20040128405
    Abstract: A data transfer control system receives a command packet ORB (SBP-2) transferred through a bus BUS1 (IEEE1394), and issues a command included in the ORB to a device connected with a bus BUS2 (ATA (IDE)/ATAPI). The data transfer control system sets a sufficiently large fixed DMA data length irrespective of the type of the issued command, and instructs start of DMA transfer to or from the device connected with the bus BUS2. The data transfer control system aborts the DMA transfer when a device connected with BUS2 informs of completion of command processing. As the fixed DMA data length, a value greater than a storage capacity of a storage or a value greater than a data length which can be designated by a command is employed. The data transfer control system issues a command included in the ORB to a device connected with the bus BUS2 without decoding the command.

  • Publication number: 20040034720
    Abstract: A data transfer control system includes: a port control section which controls ports P1 and P2 respectively connected with an electronic instrument PC1 and an electronic instrument PC2; and a bus reset issue section which issues a bus reset. The port P2 is set to a disabled state, and then the bus reset is issued to cause the electronic instrument PC1 to acquire an access right. The port P2 is set to an enabled state after the bus reset has been issued and the electronic instrument PC1 has acquired the access right. After the electronic instrument PC2 has been detected to be in a suspended state, a resume packet is transferred to the electronic instrument PC2. The port P2 is set to a disabled state after the power for the data transfer control system has been turned on.

  • Patent number: 5973081
    Abstract: A modified polyacetal is obtainable by heating 0.1 to 30 parts by weight of (B) a polymerizable compound having a modifying group such as an epoxy group, a carboxyl group or an acid anhydride group relative to 100 parts by weight of (A) a base polyacetal and introducing the modifying group of the polymerizable compound to the base polyacetal. The base polyacetal (A) includes (A1) a polyacetal selected from polyoxymethylene homopolymers and copolymers, and (A2) a polymerizable polyacetal having a functional group comprising a polymerizablly unsaturated bond. The introduction efficiency of the modifying group can be enhanced by adding 0.01 to 2.5 parts by weight of (C) a free-radical initiator relative to 100 parts by weight of the total amount of the components (A) and (B), and mixing the resultant mixture under a molten state of the polyacetal. According to such method, the affinity of the polyacetal is improved by introducing the modifying group to the base polyacetal with ease and high efficiency.

  • Patent number: 5852135
    Abstract: A resin composition comprises (1) a thermoplastic resin and (2) a modified polyacetal wherein a residue of a polymerizable compound having a functional group such as an epoxy group, a carboxyl group, an acid anhydride group or others is introduced to a base polyacetal in a proportion of 0.1 to 30% by weight relative to the base polyacetal. The thermoplastic resin includes various polymers such as an olefinic polymer, a styrenic polymer, a polyester, a polyamide and so on. The thermoplastic resins can be used singly or in combination, and the latter combination includes a combination of two or more species of resins being immiscible with each other, a combination of a polyacetal and a resin except for a polyacetal (e.g. an elastomer, etc.) and other combinations. The relative ratio of (1) the thermoplastic resin to (2) the modified polyacetal is such that the former/the latter equals about 1/99 through 99/1 (by weight).

  • Patent number: 5844059
    Abstract: To prepare a thermally very stable polyacetal copolymer containing a very small amount of unstable parts in a high yield according to a simple process wherein an isopolyacid or an acid salt thereof is used as the polymerization catalyst in the copolymerization of trioxane as the principal monomer with a comonomer copolymerizable therewith, and wherein deactivation of the catalyst can be effected simply without fail through contact with a basic gas after polymerization without the necessity for any washing step. In the preparation of a polyacetal copolymer by the copolymerization of trioxane as the principal monomer with a cyclic ether or cyclic formal having at least one carbon--carbon bond as a comonomer, the copolymerization is effected using an isopolyacid or an acid salt thereof as the polymerization catalyst, followed by contact with a basic gas as a deactivator to deactivate the catalyst, and subsequent heat-melting treatment of the resulting crude polymer intact without washing thereof.
