A reinforcing cord of the present invention is a reinforcing cord (10) for rubber reinforcement including a fiber core (11) and a plurality of strands (12) disposed around the fiber core (11). The fiber core (11) is formed of one or a plurality of highly elastic fibers having a tensile elastic modulus of at least 100 GPa. Each of the plurality of strands (12) is formed of a plurality of glass fibers that are primarily twisted, and the plurality of strands (12) are finally twisted to be disposed around the fiber core (11). The direction of the final twist of the plurality of strands is opposite to the direction of the primary twist in each of the plurality of strands (12). The number of final twists of the plurality of strands (12) is 1.0 to 3.0 times/25 mm, and a ratio of the number of primary twists in each of the plurality of strands (12) to the number of final twists of the plurality of strands (12) (the number of primary twists/the number of final twists) is in a range of 1.5 to 2.5.

A phase adjustment circuit includes: a serial-to-parallel conversion section configured to convert serial data including a synchronization pattern inserted into a predetermined position into parallel data in response to a clock; a synchronization-pattern-position detection section configured to detect the position of the synchronization pattern in the parallel data generated by the serial-to-parallel conversion section; and an adjustment section configured to adjust the phases of the parallel data and the clock to conform to a position detected by the synchronization-pattern-position detection section as the position of the synchronization pattern in accordance with information on the position of the synchronization pattern.
摘要:
An image recording apparatus which records position information of a place of shooting an image of an object and direction information of the object relative to the recording apparatus. A shooting unit takes images of an object. A receiver receives data for position measurement being transmitted from a satellite and a position information calculator calculates position information using the satellite data. A sensing unit senses a direction of a terrestrial magnetic field and a direction information calculator calculates direction information based on the sensed direction. A transmitting unit transmits the position and direction information to the recording unit which records the position and direction information on a recording medium together with image data corresponding to the taken images. The position and direction information may then be displayed together with the images when the images are reproduced.
摘要:
An RF power supplier is provided, that enables multiple-frequency RF power. The system uses N RF signal generators, combines the RF signals, amplify the combined signals, and then separates the amplified signal. The output of the system is then a multiple-frequency RF power. Optionally, the frequencies are switchable, so that one may select which frequencies the system outputs.

A lithium sulfur secondary battery is provided with a cathode containing a highly basic polymer compound in a composition or in a form of a film. The lithium sulfur secondary battery gives a longer cyclic life of charging/discharging and high energy density.
摘要:
There is provided a disulfide type electrode material that can realize a remarkably improved energy density if used in a secondary battery as well as a secondary battery that shows a remarkably improved energy density. Such an organic electrode material comprises two or more than two but not more than six continuous S--S bonds.
摘要:
A ball-and-socket joint comprising a ball stud having a ball end, a bearing into which the ball end is inserted, and a socket, the ball stud and bearing being fixedly connected to the socket by radial inward deformation of an upper end of the socket. The bearing is provided at its lower portion with a plurality of slits and a plurality of projections. The projections are pressed against the socket and deformed elastically and compressedly by the radial inward deformation of the socket.

According to the present invention, a coat is formed by applying a coating composition comprising an epoxy resin obtained by a bisphenol represented by the formula: ##STR1## wherein R.sub.1 and R.sub.2 represent a hydrogen atom or an alkyl group containing from 1 to 3 carbon atoms and a curing agent, to a substrate; and thereafter contactings the resulting coat with a liquid such as warm water or hot water in a one stage or multistage process. The thus formed coat is excellent in properties such as heat resistance, particularly erosion resistance adhesive properties and resistance to leaching of organic constituents contained in the coat exposed to hot water.
摘要:
A cell wall lytic enzyme which possesses an ability to lyse the cell wall of Chlorella, yeasts, etc. is produced by aerobically culturing a microorganism belonging to Genus Micropolyspora which produces a cell wall lytic enzyme in a medium containing assimilable carbon sources, assimilable nitrogen sources and essential inorganic salts and organic nutrients until a substantial amount of the enzyme is accumulated in said medium and isolating said enzyme from the medium, and, if desired, subjecting the thus obtained crude enzyme to the purification step of salting out or dialysis to obtain a purified enzyme solution and further subjecting the enzyme solution to freezedrying to obtain a powder preparation of said enzyme.
