An RFID tag which has improved radiation/reception characteristics when used in proximity to the human body, and has an antenna which, when stacked with a 13 MHz band RFID tag, does not have an effect on the loop antenna of that tag. An RFID tag assembly comprises a first RFID tag having a coiled loop antenna and a second RFID tag superposed on the first RFID tag, the second RFID tag comprising an antenna formed by a metal member which covers at least a portion of a surface of a dielectric substrate, an electronic part mounted on the metal member, and a member which is provided with the overlapped coiled loop antenna of the first RFID tag housed in the end thereof so as to cover a portion of the antenna formed by the metal member.

A distortion compensating apparatus calculates a distortion compensation coefficient in such a manner that a difference signal between a reference signal, which is a transmit signal, and a feedback signal will be diminished, updates an old distortion compensation coefficient by the calculated distortion compensation coefficient and applies distortion compensation to the transmit signal based upon this distortion compensation coefficient. In this apparatus, a phase correcting interval, which is for correcting the phase difference between the reference signal and the feedback signal, and a distortion compensation coefficient updating interval are generated alternately, a correction is applied so as to null the phase difference in the phase correcting interval, and the distortion compensation coefficient is updated in the distortion compensation coefficient updating interval.

A damper unit includes a gear having a core member projecting at a shaft core portion thereof and rotatably housed in a case, a string wound around the core member, a rotary damper engaging the gear for damping a rotational force of the gear, and a spring. One end of the spring is fixed to the case and the other end thereof is fixed to the core member so that an elastic force is accumulated when the string is pulled out.

A lower double-joint front suspension system is provided which includes an upper suspension link and a pair of lower suspensions links for supporting a front wheel. The suspension system is adapted to provide a positive scrub radius for a front wheel when the front wheel is steered to serve as an inner wheel during cornering, which positive scrub radius increases with increase of turning of the front wheel away from a neutral position thereof. One of the lower suspension links, which is located in the rear of the other, has a connecting end portion at which it is connected to a vehicle body. The connecting end portion includes a resilient bushing which is less rigid in the width direction than in the longitudinal direction of the vehicle body. By this, when a braking force is applied to the steered inner front wheel during cornering, the resilient bushing is deformed in the width direction and inboard of the vehicle body. Such deformation of the resilient bushing causes rear one of the lower suspension links to turn in the direction to decrease the positive scrub radius, thus making it possible to improve the returnability of a steering wheel.

Second connectors 61x are fixed symmetrically with respect to a steering shaft 10 on a steering post 20 in such a manner that these second connectors are slightly movable, and a steering unit 30 is moved parallel to the axis of the steering shaft 10, thereby connecting two first connectors 62x, fixedly mounted on the steering unit 30, to the second connectors 61x, respectively. Lever-type connectors, having the function of reducing a load exerted during the connecting operation, are used as the first and second connectors 62x and 61x, respectively.

A rolling mill for metal foil includes a pair of work rollers having axes in parallel to each other for subjecting a sheet material being supplied therebetween to strip processing, two pairs of intermediate rollers arranged so that the intermediate rollers of each pair are in contact with one of the work rollers and have axes in parallel to the axis of the contacting work roller, and two pairs of backup rollers arranged so that the backup rollers of each pair are respectively in contact with one pair of the intermediate rollers. Each pair of intermediate rollers and the pair of backup rollers in contact with the pair of intermediate rollers impart roll load to the work roller in contact with the pair of intermediate rollers. The rolling mill enables the production of large-width metal foil too thin to be self-supportable in shape with ease and high precision.

The present invention provides an aqueous marking pen ink composition for writing board which gives writing that can be easily erased by wiping with a dry erasing material without staining on the surface of the writing board even if the writing is half-dried, not to mention after dried on the surface of the writing board. The novel aqueous marking pen ink composition for writing board comprising as essential components a colorant, a resin, a separating agent and water, wherein the colorant comprises microcapsules containing a coloring substance selected from the group consisting of oil-soluble dye, disperse dye and pigment and oil medium which dissolves or disperses a coloring substance. Writing drawn on the surface of a writing board with the aqueous marking pen ink for writing board according to the present invention can be easily and completely erased by wiping with a dry erasing material regardless of whether it is half-dried shortly after drawn on the writing board or after thoroughly dried.

A connector connecting structure comprises a first connector supported on a mounting portion, and a second connector connected to the first connector. A spherical support portion is formed in a projected manner on one of a bottom of the first connector and a wall surface of the mounting portion, while a holding portion for holding the support portion is provided on the other, and when connecting the second connector to the first connector, the first connector is pivotally displaced about the support portion.

A temperature-dependent color/transparency storing resin layer is composed by dispersing and fixing a mutually dissolved homogeneous composition consisting of (A) an electron-donating color-developing organic compound, (B) a compound having a phenolic hydroxyl radical, and (C) a compound selected from alcohols, esters, ketones and carboxylic acids, in vinyl chloride-vinyl acetate-copolymer matrix resin, as small particles, and capable of exhibiting reversible change in color and in transparency in response to a temperature variation with hysteresis, and selectively storing a state developed above the high trigger temperature and a state developed below the low trigger temperature in a temperature range between the high and low trigger temperatures, wherein the transparency is improved by blending vinyl chloride-vinyl acetate-vinyl alcohol copolymer and/or vinyl chloride-vinylidene chloride copolymer as an agent for improving the transparency in said matrix resin so as to regulate the transparency and to conspicuously improve the transparency especially exhibited in a temperature range above the high trigger temperature, so as to constitute a laminate member to be applied in various fields.
摘要:
A water-resistant electrical connector includes a housing having at least one cavity dedicated to receive a terminal fixture and at least one cavity which is configured to prevent a terminal fixture from being inserted therein. Although both of the cavities are open at opposite ends of the housing, a wall closes up the cavity which is not to receive a terminal fixture constituting an electric circuit. This wall presents water from passing through the cavity from one side of the housing to the other. A fin also extends across this cavity from an open end of the cavity to the wall to thereby prevent a terminal fixture from being inserted in the cavity and into contact with the wall. A molding system can manufacture connector housings having various combinations of the cavities configured to receive a terminal fixture and cavities which prevent a terminal fixture from being inserted therein. The molding system includes a fixed mold, a movable mold, and pairs of mold pins which are detachably mountable to the molds. One pair of the mold pins will form a cavity configured to receive a terminal fixture while another pair of the mold pins will form a cavity which will prevent a terminal fixture from being inserted therein. The respective pairs of mold pins are interchangeable so that the same molds can be used to manufacture various types of housings depending on the circuit to which the connector is applied.
