  • Publication number: 20050206921
    Abstract: According to the present invention, there is disclosed an image forming apparatus comprising a constitution driven/controlled independently for each recording head. The apparatus rewrites image data or parameters or changes a driving voltage at a desired timing, and realizes a uniform or appropriate density of an image formed by control of an ink spout amount based on a temperature detection signal of the recording head detected by a temperature detection unit disposed in each recording head. The apparatus is capable of remarkably narrowing a mutual conveying interval among a plurality of conveyed recording mediums.

  • Patent number: 6540698
    Abstract: A highly safe medical device which exhibits long-lasting low surface friction in a body fluid or in an aqueous medium is provided. Also provided is a method for producing such medical device wherein substantially no limitation is imposed on the type of the substrate used, and the hydrophilic high molecular weight compound or the water-soluble or water-swellable high molecular weight compound responsible for the surface lubricity can be readily coated on the surface. In the present invention, a hydrophilic high molecular weight compound having at least one carbonyl group or hydrazine residue in the molecule and a cross-linking agent having at least two hydrazine residues or carbonyl groups in the molecule are reacted to thereby form a surface lubrication layer comprising the reaction product.

  • Patent number: 5441488
    Abstract: This invention provides a medical tool the surface of which is enabled to acquire lasting lubricity (low friction) by assuming a state wetted with bodily fluid or aqueous solution. This surface is formed without requiring the coating work to be repeated. The medical tool is produced by coating a water-swellable polymer having in the molecular unit thereof a reactive functional group capable of being reacted with a proton-donating group, on the surface of a matric material possessing the proton-donating group, and also by coating a water-swellable polymer having in the molecular unit thereof a reactive group capable of being reacted with an acid anhydride group on the surface of a matric material possessing the acid anhydride group.

  • Patent number: 5070293
    Abstract: An electric power transmitting device transmits electric energy from one coil to another coil through an inductive coupling therebetween. One of the coils has an end bent in the axial direction of the coil. When the other coil is to be inserted into said one coil, it can be inserted in not only the axial direction of said one coil, but also a direction transverse to the axial direction through the bent end of the coil. Said one of the coils is typically housed in a holder, and the other coil in the grip of a gun-shaped, hand-held bar-code scanner. When the grip is inserted into a groove defined in the holder, the coils are magnetically coupled to each other, thus providing an inductive coupling. The bar-code scanner can easily be placed on and removed from the holder.
