|20140299349||HIGH-SPEED SIGNAL TRANSMISSION CABLE - A high-speed signal transmission cable includes a coaxial wire assembly, a shield layer arranged around an outer periphery of the coaxial wire assembly, and a sheath, arranged around as the outermost layer. Each coaxial wire includes an inner conductor, a hollow core member, and an outer conductor. The outer conductor is formed by longitudinally adding a metal foil or a plastic tape having a metal layer on an outer periphery of the hollow core member. The high-speed signal transmission cable can suitably transmit a high-speed digital signal of 10 Gbps and above, and its characteristics do not degrade easily even if it is used on multiple cores twist structure or bending. Therefore, the high-speed signal transmission cable can be used in environments that require high-speed transmission of digital signals.||10-09-2014|
|20100219952||Property Retrieving System - An operating unit is fixedly mounted to a property as being accompanied with an active type RF tag unit. When the property to be retrieved is demanded by a user using an upper level unit, its demand is transferred from the upper level unit to an installation type transceiver unit, from the installation type transceiver unit to the active type RF tag unit, and from the active type RF tag unit to the operating unit which then directs the alarming means to emit at least either lights or sounds. This allows the user to recognize the location of the property in a warehouse. When the property is moved, its assigned active type RF tag unit is detached from the operating unit.||09-02-2010|
|20100045580||IMAGE DISPLAYING APPARATUS AND IMAGE DISPLAY PROGRAM - An original monochrome image recorded with an FPD (flat panel detector) which comprises an array, m rows and n columns, of pixels is reduced and converted into a display image which comprises an array, q rows and (3*n*q/m) columns, of pixels before the display image is transferred to a monochrome liquid crystal display equipped with a monochrome LCD which comprises an array, q rows and P columns, of pixels, where m, n, q, and P are natural numbers and m≦n, q|
q are given. The monochrome liquid crystal display drives the three sub pixels of each pixel independently aligned along the row of the monochrome LCD to display the display image of the pixels in q rows and (3*n*q/m) columns.

|20090067188||LIGHT SOURCE - A first optical waveguide guides a pumping light emitted from a semiconductor laser. A second optical waveguide absorbs the pumping light and emits a spontaneous emission light having a wavelength longer than that of the pumping light. A third optical waveguide guides a light output from the second optical waveguide to outside. A wavelength selecting element is provided between the second optical waveguide and the third optical waveguide, across which a resonator is formed between the semiconductor laser side and an output side to outside. A wavelength of a laser light emitted from the resonator is set by controlling length of the second optical waveguide.||03-12-2009|
