An RFID tag that includes a base, an antenna for communication wired to the base, a circuit chip electrically connected to the antenna for radio communication via the antenna, a first reinforcing member and a second reinforcing member. The first reinforcing member covers and fills the whole of the circuit chip and part of the antenna. The second reinforcing member is positioned underside of the first reinforcing member across the base and has an edge that is displaced from the edge of the first ...

An RFID tag, including: a base; an antenna pattern that is provided on the base to form a communication antenna and has a tapered connection end portion which provides a connection terminal to the antenna; an electric conductor that is attached onto the connection end portion of the antenna pattern and is smaller than the connection end portion; and a circuit chip that is electrically connected to the antenna pattern via the electric conductor and performs radio communication by use of the anten...

An electronic part mounting structure includes a printed circuit board, a plurality of electronic parts mounted on the printed circuit board, a folded portion of the printed circuit board bent and layered between the electronic parts, through holes formed in both sides of the folded portion, and a wiring connecting the electronic parts via the through holes and connecting the electronic parts to the through holes.

A RFID tag includes an inlet in which an antenna for communication and a circuit chip performing radio communication with the antenna are electrically connected to each other. The RFID tag further includes a thermal storage section which encloses the inlet, which is made of a nonmetal, and which prevents thermal diffusion into the inlet and a thermal insulating section which encloses the thermal storage section, which prevents thermal conduction to the thermal storage section, and which has high...

Aromatic hydrocarbons which have undergone nuclear substitution with a trifluoromethyl group are electrolytically fluorinated in anhydrous hydrogen fluoride. The mixed gas which is consequently formed is sent through the aqueous solution of sodium sulfite containing therein potassium iodide, thereafter cooled and collected, and subjected to refining treatment such as by trap-to-trap distillation, distillation, or gas chromatography to obtain perfluorocyclohexane derivatives.

Aromatic hydrocarbons such as, for example, trifluoromethyl benzonitrile and bis-(trifluoromethyl)-benzonitrile which are composed of benzene derivatives having nitrile and trihalogenated methyl substituted for hydrogens of benzene are dissolved in anhydrous hydrogen fluoride and the solutions are electrolyzed to produce perfluoro-alicyclic hydrocarbons composed of perfluorocyclohexane derivatives having trifluoromethyl substituted for fluorine of perfluorocyclohexane.

Partially chlorinated ethers are electrolytically fluorinated in anhydrous hydrogen fluoride. The gas which is produced consequently is passed through water and the aqueous solution of sodium sulfite-sodium hydroxide for the removal of by-products and thereafter cooled and collected. The collected product is a mixture consisting of fluorinated ethers and fluorocarbons. Chlorofluoroethers which the present invention aims to obtain are separated from this mixture by additional treatments of distil...

Trichloropolyfluoro-bicyclo ethers are novel compounds, useful as a solvent or thermal medium for various pharmaceutical chemicals. They are produced by the reaction of perfluoro-bicyclo ether with anhydrous aluminum chloride.

With the RFID comprising a transmitting and receiving antenna, a detecting block formed in the circumference of the antenna, and an electronic component connected to the antenna and detecting block to detect breakdown of the detecting block, illegal use can be prevented, matching between the tag antenna and IC chip can also be attained with inclusion of the detecting means, and higher radiation and receiving characteristics of antenna can also be obtained without deterioration of antenna gain. M...

A radio-frequency-identification tag antenna includes a film base, a plurality of antenna patterns for transmission and reception, which is formed in parallel on the film base, and a cut line that is formed on the film base between adjacent antenna patterns along the antenna patterns from an inside to an outer edge of the film base. A part of the film base on which the antenna patterns are formed is folded or bent in a predetermined direction using the cut line.
