摘要:
An antenna device includes an antenna element 10 and a printed circuit board 20 on which the antenna element 10 is mounted. The antenna element 10 includes a base 11 which is made of a dielectric material and a radiation conductor formed on at least one surface of the base 11. The printed circuit board 20 includes ground clearance region 23a having substantially a rectangular shape and having one side contacting an edge of the printed circuit board and other three sides surrounded by an edge line of a ground pattern, an antenna mounting region 27 provided within the ground clearance region 23a, and at least one frequency adjusting element 30 provided within the ground clearance region 27. The frequency adjusting element 30 is provided on the far side of the antenna mounting region 27 as viewed from an edge 20e of the printed circuit board 20.

A surface mount antenna with small size and broadband is provided. The surface mount antenna includes: a substrate including a dielectric material or a magnetic material as a main material; a feed radiation conductor formed on the substrate, one end of the feed radiation conductor being a first feed end to be supplied with power, and the other end being a first open end; and a parasitic radiation conductor formed on the substrate at a distance from the feed radiation conductor, one end of the parasitic radiation conductor being a second feed end to be supplied with power from the feed radiation conductor through electromagnetic coupling, and the other end being a second open end. A region having a dielectric constant or a magnetic permeability lower than that of the main material of the substrate is provided between the feed radiation conductor and the parasitic radiation conductor.

The invention provides an optical waveguide including a resin substrate containing an inorganic filler, and at least a UV-absorbing layer, a lower cladding layer, a patterned core layer, and an upper cladding layer laminated above the resin substrate in this order, wherein the core layer has been patterned through light exposure and development, and the UV-absorbing layer has a thickness of 10 to 50 μm, and a method for producing an optical waveguide, including a step of forming a UV-absorbing layer on a resin substrate containing an inorganic filler; a step of forming a lower cladding layer on the UV-absorbing layer; a step of forming a core layer on the lower cladding layer; a step of subjecting the core layer to light exposure to thereby transfer a pattern having a given shape to the core layer; a step of developing the core layer to thereby form a core pattern; and a step of forming an upper cladding layer on the patterned core layer. According to the present invention, an optical waveguide having a high-resolution core pattern can be produced.
摘要:
Data of textiles for various types of items offered by a different textile company stored in an integrated database (DR) of a data service company item by item, and data of business results relating to the respective items is also stored therein. Data of business results stored in the integrated DB is renewed based on business data sequentially input from an apparel manufacturer or the textile company. In retrieving textile data from the apparel manufacturer or the textile company, a host computer (integrated database managing system) of data service company retrieves sale data based on the content of the textile in the integrated DB and the content of the business results relating to the content of the textile, and displays the retrieved result on a terminal, which designated the retrieval, that is, a terminal of the apparel manufacturer or a terminal of the textile company. In this case, it is noted that the host computer displays the retrieved result on the terminal (company), which designated the retrieval, in the form of second data in which read data is processed in a case where the terminal, which designated the retrieval, is not a designated enterprise, which is not allowed to refer to retrieved data by the company, which offered the corresponding data.
