摘要:
A specific access space for each user is selectively specified in the hypertext space having mutual link relation between one or more hypertexts provided by one or more servers. An analysis unit interprets a page request from a user and extracts the URL and space identification information of the requested page information. A page information request unit requests for the page information to be referred to by the extracted URL to the WWW server. A specific information addition unit takes out the link comment data corresponding to the space identification information and synthesizes a page by adding the comment to the received page information. The page synthesized page information instead of the requested page information is returned to the requester user.
摘要:
A laminate type piezoelectric element having an improved piezoelectric property is provided. Vibration electrodes are arranged in a piezoelectric body, and high-order vibration of the thickness vibration is excited. The piezoelectric ceramic includes two ceramic piezoelectric layers which are laminated, and are integrally formed. Each of the ceramic piezoelectric layers contains ceramic crystal grains having shape anisotropy and spontaneous polarization preferentially oriented in one plane. The in-plane direction of this plane is perpendicular to the principal surfaces of the ceramic piezoelectric layers. The ceramic piezoelectric layers are polarized in the same thickness direction.

Disclosed is a sanitary ware which has a self-cleaning function for releasing carboxyl-containing greasy stains or soils, such as fatty acids, fatty esters, metallic soaps (scum of soaps), proteins, amino acids, bacteria, and fungi, and deposited stains or soils, such as water scale and urinary calculi. This sanitary ware comprises at least a sanitary ware body and a glaze layer as an outermost layer of the sanitary ware, a monovalent metal component and/or a metal component having a measure of the electronegativity based on Pouling's rule of not more than 1 being provided so as to be releasable evenly and continuously, over the whole surface of the glaze layer as the outermost layer, in such an amount large enough to impart a self-cleaning function for releasing stains or soils to the surface of the glaze layer as the outermost layer, the metal component being suppliable from the glaze layer as the outermost layer and/or the sanitary ware body to the whole surface of the outermost layer. The sanitary ware is advantageous in that stains or soils on the sanitary ware can be simply removed, for example, by running water without using any surfactant and without strongly scrubbing the surface of the sanitary ware by a scrubbing brush or a cleaning brush.

摘要:
In a discharge lamp sealing apparatus 30, luminescent substances are charged into an arc tube 11 through an opening 13b thereof, and an electrode member 15 is then inserted into the arc tube 11 through the opening 13b. A lower end of the arc tube 11 is supported by a support jig 57 in a state that a glass ring 16c is placed around the circumference of the opening 13b. The arc tube 11 is set in an air-tight condition by a feeding conduit 51 and inserted into a heating unit 40. The heating unit 40 fuses the glass ring 16c with heat of an infrared lamp and thereby seals the opening 13b. During the sealing process, one end of the arc tube 11 is supported by the support jig 57. The support jig 57 is mainly made of a material having a greater thermal conductivity than that of the material of the arc tube 11, for example, a metal material like Al or Cu. This arrangement enables heat to be readily conducted from the arc tube 11 to the support jig 57 and accordingly prevents a temperature rise in the arc tube 11. This prevents the luminescent substances from being vaporized and released from the arc tube 11.

摘要:
A piezoelectric element has a very small size, has a high coefficient of electromechanical coupling, and can easily be impedance-matched to a circuit. An interdigital electrode, including two comb-shaped electrodes, is provided on one surface of a plate-like piezoelectric member, and similarly, an interdigital electrode, including two comb-shaped electrodes, is provided on another surface of the plate-like piezoelectric member. The piezoelectric member is polarized by applying electrical fields between the two respective pairs of comb-shaped electrodes; and in addition, by applying an electrical field for excitation between a terminal connecting one of the comb-shaped electrodes to each interdigital electrode, and another terminal connecting the other comb-shaped electrodes to each interdigital electrode, longitudinal vibrations in a stiffened mode are excited, whereby the piezoelectric member expands and contracts in the longitudinal direction thereof.
