  • Publication number: 20140302732
    Abstract: An oceanographic information collection system includes an anchor arranged on a sea bottom, an intermediate buoy connected to the anchor and floating in a sea, a mooring cable connected at one end to the intermediate buoy and at another end to an observation buoy. The observation buoy includes a main body whose longitudinal direction is arranged in a flowing direction of an ocean current. A specific gravity adjuster is arranged in the main body and includes an expandable and shrinkable buoyancy bag, an antenna arranged on the main body and transfers data, and an observation unit arranged in the main body and acquires prescribed oceanographic information. The observation buoy floats upward by expanding the buoyancy bag of the specific gravity adjuster, and sinks by shrinking the buoyancy bag in order to stand by in the sea. The buoy can easily float, sink and stand by in the sea.

  • Patent number: 7135253
    Abstract: To provide a lithium secondary battery with a high critical discharge current even under a low temperature condition, with an excellent cycle characteristic and reduced manufacturing cost. The lithium secondary battery includes a wound type electrode body comprising a positive electrode plate, and a negative electrode plate both of which have been wound around a core via a separator, the electrode body being impregnated with a non-aqueous electrolyte, and a cylindrical case for housing the electrode body and the non-aqueous electrolyte; the case having at least one opening at either end thereof, which can be sealed. The separator is subjected to drying treatment after the electrode body is inserted into the cylindrical case.

  • Patent number: 7087126
    Abstract: A mounting apparatus includes: a heater head for bonding a liquid crystal display and a flexible printed circuit board by thermocompression; a cylinder as a heater head driving means for driving heater head to compress the liquid crystal display and flexible printed circuit board by a prescribed load; and a control mechanism as a stretch amount controlling means for adjusting a load change per unit of time after the heater head starts compressing the flexible printed circuit board by the cylinder as well as a time at which a required load is attained to control the stretch amount of the flexible printed circuit board by thermocompression. Preferably, the mounting apparatus is provided with a mechanism which performs measurement after preliminary bonding and which performs regular bonding while controlling based on the obtained information.

  • Patent number: 6977707
    Abstract: A wiring substrate is arranged so that a first periphery electric wiring and a second periphery electric wiring are patterned on an active matrix substrate, and a TCP as a electronic component is provided on a portion of the patterned electric wiring. The first periphery electric wiring and the second periphery electric wiring are formed by including a metal thin film and a transferred metal film. Further, in the portion where the TCP is provided, the first periphery electric wiring and the second periphery electric wiring either have a monolayer structure with one of the metal thin film and the transferred metal film, or have a lamination structure with both of the metal thin film and the transferred metal film. On this account, connection failure can be prevented on a low resistance wiring substrate.
