摘要:
The present invention provides a new copolymer of propylene and a conjugated diene having a carbon-carbon double bond in a side chain, wherein a molar ratio of a total of 1,2-adducts and 3,4-adducts to 1,4-adducts, derived from the conjugated diene, is 100:0. The copolymer is prepared in a process, characterized in that propylene and the conjugated diene are copolymerized in the presence of hydrogen, an organometallic compound comprising a transition metal selected from the group 4 of the periodic table, and at least one Lewis acid.

A main memory data rewriting device includes a rewrite condition analysis unit configured to analyze a rewrite condition for target data in main memory data stored in a main memory before deactivation of an information processing device, and create a first processing content to acquire environment data substituting the target data from outside of the information processing device and a second processing content to rewrite the target data to the environment data, an environment data processing unit configured to acquire the environment data according to the first processing content when the information processing device is temporarily activated at an activation time set to rewrite the target data during a deactivating period of the information processing device, and a rewrite processing unit configured to rewrite a region of a nonvolatile storage medium in which the target data is stored with the environment data according to the second processing content.
摘要:
The invention relates to microporous membranes having high meltdown temperature, low shutdown temperature, and resistance to heat shrinkage at elevated temperature. The membranes can be produced by stretching a sheet comprising polymethylpentene, polyethylene, and diluent, and then removing the diluent. The membranes can be used as battery separator film in, e.g., lithium ion batteries.

Shielding structure for use in an electronic device comprising a housing and an electronic substrate which is arranged in the housing and which includes electronic parts, wherein the housing includes at least a surface facing the electronic parts, the surface being made of an electrically conductive substance. There is disposed a shielding member made of electrically conductive material comprising a frame-shaped section disposed on the printed board to surround a periphery of the electronic parts and a leaf spring section disposed to project from an upper-edge section of the frame-shaped section toward the inside of the frame-shaped section and upwardly in an inclined direction. The shielding member is disposed on the electronic substrate, and the surface made of an electrically conductive substance of the housing pushes the leaf spring section to be brought into contact therewith.

A relay device includes a reception unit which receives a startup packet including a first ID for starting up controllable equipment. The relay device also includes a transmission unit which transmits a first electric signal indicating the first ID to all link-downed Ethernet ports.
摘要:
An information providing system includes a portable terminal, and a server that provides the portable terminal with information of an arrival time of the portable terminal at a destination. The portable terminal comprises an RFID tag to which identification information of the destination and identification information of a departure place are written; and a communication unit that transmits the destination identification information, the departure place identification information, and information of a departure time which is a current time to the server when triggered by the departure place identification information written in the RFID tag. The server comprises an arrival time deriving unit that derives the arrival time at the destination using the departure place identification information, the destination identification information, and the departure time information transmitted from the portable terminal; and a communication unit that transmits the information of the arrival time at the destination to the portable terminal.
