Abstract: A head for electrical scalpel includes a member that is composed of a ceramic(s), and an electrode rod where at least a part thereof is positioned in the member, wherein a surface that contacts the electrode rod on the member is configured in such a manner that a skewness Rsk that is obtained from a roughness curve is positive.

Abstract: A light-emitting element mounting substrate and a light-emitting device. The light-emitting element mounting substrate is composed of an alumina-based sintered body. The alumina-based sintered body contains 80 percent by mass or more of aluminum oxide with respect to 100% by mass of all constituent components. An O/Al atomic ratio of oxygen to aluminum in crystal grains of the aluminum oxide is less than 1.5.

Abstract: A dielectric ceramic includes a main crystal phase containing Ba, Nd and Ti; and a remainder, part of Ti contained in the main crystal phase being substituted with Al, a content of the Al contained in the main crystal phase to a total content of Al in the main crystal phase and the remainder being greater than or equal to 10% on Al2O3 basis. Accordingly, provided is a dielectric ceramic having a high relative permittivity ?r, a high Qf value and a stable resonant-frequency temperature coefficient ?f close to 0 ppm/° C. Also provided is a dielectric filter which is provided with the dielectric ceramic and in which a desired relative permittivity can be obtained with stability and a high Qf value can be obtained, and excellent performance capability can be maintained for a long period of time with stability in a place where wide temperature variations are encountered.

Abstract: Provided is a dielectric ceramic containing yttrium, manganese, and aluminum, and having a composition formula expressed by ?BaO.?Nd2O3.?TiO2, wherein mole ratios ?, ? and ? satisfy 14???21, 4???21, and 65???75, respectively. In this case, the equation: ?+?+?=100 is established.

Abstract: An ink replenishing apparatus replenishes an ink cartridge, which has an ink absorber made of a porous body or fiber bundle in an ink storage chamber that stores ink, with ink supplied from a replenishing ink cartridge through a relay core. An ink holding force d of capillary tubes of the relay core and an ink holding force D of capillary tubes of the porous body or fiber bundle satisfy the following relation d<D.

Abstract: A replenishing ink cartridge capable of quickly replenishing a printing cartridge with an ink is provided. The replenishing ink cartridge includes the printing cartridge and a replenishing cartridge for replenishing the printing cartridge with the ink. An ink absorber made of a porous body or fiber bundle is stored in an ink storage chamber of a case of the printing cartridge. An ink supply nozzle to be inserted in the ink absorber is arranged in an ink storage portion of the replenishing cartridge, and a substantially funnel-shaped press member which is to come into contact with the surface of the ink absorber is fitted and mounted on the distal end portion of the ink supply nozzle.

Abstract: On the surface of an ink-permeable sponge material having open cells, a melted portion and an unmelted portion are formed by a thermal head printer controlled by a memory processor for desired imprint data to prepare a stamp having the unmelted portion as an ink oozing imprint surface. Furthermore, a stamp material plate comprising the tape-like sponge material is wound up in the form of a roll and then received in a cassette case, and a stamp material cartridge comprising this cassette case is mounted in a cartridge receiving section of the thermal printer capable of printing in a tape form. A print image set by input from a keyboard or external input is printed on the stamp material comprising the sponge material fed from the cartridge by the thermal head, while the stamp material is pressed, to form a concave having a depth of 0.01 mm or more, thereby preparing a print plate for a stamp having a suitable length.

Abstract: A stamp and a process of producing a stamp includes a stamp that is made from a sponge having open cells to allow repeated impressing operations without supplying stamp ink for a long time. The process includes fitting a heat-fusing ink sheet or a heat-generating plate, which contains a heat-generating material, over the surface of a stamp-piece that has open cells therein. A liquid substance soaks a manuscript having characters, patterns, etc., which are represented by non-applied areas of recording material. The manuscript is placed over the top in such a manner that an image may appear to be a mirror image. The manuscript is irradiated from above with light to cause light to pass through the non-applied areas of recording material to increase the temperature of the heat-generating material at sites corresponding to the non-applied areas of recording material.
