Abstract: The present invention provides for a method for the pretreatment of a surface and/or reservoir, in particular a plastic surface preferably a reservoirs and more in particular filter membranes enclosed therein, for the reduction of non-specific binding by chemical entities, such as but not limited to small organic molecules with bodily fluids such as blood serum proteins, to said reservoirs, whereby the method makes use a non ionic surfactant or, a cationic surfactant or both kinds of surfactants. The invention also concerns kits for enabling the method described above.

Abstract: Disclosed is a portable hemodialyzer, which not only can relieve a patient from the pain of putting injection needles into two portions of the patient's body for hemodialysis, but also enables the hemodialysis to be safely performed even at home, so as to reduce the times by which the patient must visit the hospital, thereby largely reducing time and expense. In the portable hemodialyzer, an injection needle contains a separation film separating an introduction channel and a discharge channel from each other, which are formed in the injection needle. A blood exit is formed at a predetermined left side portion of the injection needle, while a blood entrance is formed at a predetermined right side portion of the injection needle.

Abstract: Disclosed is a wireless transmitting and receiving antenna which comprises a bobbin made of insulation material and having a first penetration cavity in the center of the bobbin in a lengthwise direction; a first antenna comprising a helical conductor spirally wound on the bobbin and having a resonance frequency, and a matching bar inserted into the cavity of the bobbin, made of a conductor and providing a second penetration cavity in the direction identical with that of the first penetration cavity; a feeder positioned at one part of the bobbin so as to supply signals to the helical conductor; and a second antenna comprising: a rod inserted into the penetration cavities of the bobbin and the matching bar, moving between the penetration cavities in a slipping manner, and wrapped with the insulation material; a conduction material combined to the outer part of the rod, and electrically connecting the feeder and the helical conductor when the rod is inserted into the penetration cavities; and a stopper which is

Abstract: The present invention relates to a method for forming a gate of a semiconductor device that uses a cobalt silicide. The method for forming the gate of the semiconductor device can include preparing a semiconductor substrate, form a first insulation layer on the semiconductor substrate, form a doped polycrystalline silicon layer simultaneously with a deposition or after the deposition and forming a cobalt silicide layer by another deposition or by reacting a cobalt layer with the polycrystalline silicon layer. The cobalt silicide layer is selectively removed by using at least one etchant gas selected from a group of a gas including a chlorine atom group, a gas mixture of the gas including the chlorine atom group and oxygen, a gas mixture of the gas including the chlorine atom group and an inert gas, and a gas including the above-enumerated gases and a gas having a fluorine atom group. Then, the polycrystalline silicon layer is patterned.

Abstract: A fluid jetting apparatus for a print head employed in an output apparatus, and a manufacturing process thereof. The process for manufacturing a fluid jetting apparatus includes: (1) forming a heat driving part having a sacrificial layer; (2) forming a membrane on the heat driving part which includes the sacrificial layer; (3) forming a nozzle part on the membrane; and (4) removing the sacrificial layer. The step (1) further includes: (i) forming an electrode and an exothermic body on a substrate; (ii) laminating a working fluid barrier on the electrode and the exothermic body, and forming a working fluid chamber in the working fluid barrier; (iii) forming a protective layer on the working fluid barrier, the electrode, and the exothermic body; (iv) forming a sacrificial layer within the working fluid chamber at a same height as the working fluid barrier.

Abstract: An electrostatic attraction type inkjetting apparatus including aboard having an ink chamber for receiving ink and a nozzle hole extending from the ink chamber to the extreme end of the board and thus open at the extreme end of the board; a membrane laminated on the board; a lower electrode received in the ink chamber; and an upper electrode disposed on the outer surface of the membrane. By the electrostatic attraction generated during an electric potential difference application between the upper and lower electrodes, the membrane is deformed inward to the ink chamber to press the ink of the ink chamber. Thus, the ink is jetted outward through the nozzle hole. Since the membrane and the driving section are integrally formed with each other, the manufacturing process becomes simpler, and electrostatic attraction generation, and ink discharge are performed efficiently.

Abstract: A pointing device for controlling cursor movement on a computer display by entering positional information into the computer includes: a housing having an upper opening and a lower inside base directly facing the upper opening; a cylindrical bar mounted on the lower inside base so as to rotate around and slide along its central axis in the upper opening; a plurality of first marking lines disposed around a part of the periphery of the cylindrical bar adjacent to one end thereof, the first marking lines being in parallel with the central axis and having a constant interval between adjacent marking lines, and the first marking lines being extended to a given length from the one end; a plurality of second marking lines disposed around another part of the periphery of the cylindrical bar adjacent to another end thereof, the second marking lines being perpendicular to the first marking lines and having a constant interval between adjacent marking lines, the second marking lines being extended to a given length fro
