Title: Electron gun structure body for linear beam type electron tube
Inventor: IMAIZUMI MASAE
IPC: H01J23/06
Filed: 1987-06-29
Abstract: PURPOSE:To facilitate the production of grid electrodes and the assembly including a cathode by applying the same radius of curvature at the normal temperature to the electron emitting face of the cathode and faces of the grid electrodes on the accelerating electrode side. CONSTITUTION:A cathode 11, multiple grid electrodes, i.e., the first grid electrode 13 and the second grid electrode 14, a beam focusing electrode 15, and an accelerating electrode 17 are arranged respectively at the preset intervals along an electron beam axis (z). The radius of curvature R1 of the face of the first grid electrode 13 on the accelerating electrode side and the radius of curvature R2 of the face of the second grid electrode 14 on the accelerating electrode side are formed equally to the radius of curvature Rc of the electron emitting face 12 of the cathode at the normal temperature. The grid electrodes 13, 14 merely need to be moved in parallel in the beam axis direction and assembled at the preset intervals on the beam axis to the cathode 11 although the aligning of radial grid lines 13b is performed of course. The production and assembly can be thereby simplified.

IPC: B03C1/00
Filed: 1992-05-08
Abstract: PURPOSE:To furnish a novel treating method wherein impurity components such as Zn, Pb, Cl, etc., are removed and collected from electric furnace dust containing these components, while an iron content is returned in the form of higher purity to an electric furnace, and an exhaust gas is made harmless. CONSTITUTION:Solid carbon and ferric chloride in the form of fine powder are added to and mixed in electric furnace dust containing Zn, Pb, Cl, etc., and mixing kneading, granulation and drying are conducted. Thereafter the dust thus processed is subjected, together with an externally charged carbon material, to reduction, chlorination, volatilization and roast in a heating furnace such as a rotary kiln and thereby Zn and Pb are volatilized and removed as chloride, while an iron content is reduced. A burned material thus produced is subjected to magnetic separation and a magnetized material is supplied to an electric furnace as an electric furnace material, while a non-magnetized material is classified or sieved, so as to remove an ash content therefrom, and added to the externally charged carbon material for circulation. The chloride volatilized in an exhaust gas is led to a vertical type packing tower or the like, deposited and precipitated on a packed material and removed. Thereafter a hydrogen chloride content in the exhaust gas is removed by adsorption by blowing ferric hydroxide, limonite, iron oxide in the form of fine powder, or the like, into the exhaust gas, while the chloride thus treated is collected by a dust collector and supplied as the ferric chloride to a head for circulation.

Title: Donor drum of direct recording system printer
Inventor: NOMURA MASAAKI
IPC: G03G15/05
Filed: 1978-12-20
Abstract: PURPOSE:To achieve the ease of production and the evenness of toner image densities by specifying the constitution of a donor member. CONSTITUTION:Non-magnetic material 1b such as synthetic resin or glass is deposited to a fixed thickness on the surface of a cylindrical support frame and fine conductors 1d having been insulated of surfaces such as enameled wires are subsequently folded in a fixed direction and are arrayed at a fixed spacing in the non- magentic material 1b. These are also subsequently arrayed by crossing with these at a right angle and at a fixed spacing to be wired to grating form as a whole, whereby the cylindrical surface C of the toner member 12 is formed. If with this arrangement current is supplied to the fine conductors 1d through a ring brush 1e by a control means 9, the magnetic fields generated are applied to each fine surface E and at the same time the superposition and offsetting take place in each fine surface E depending upon the directions of magnetic lines of force, and this causes the ferromagnetic fine surfaces E1 and magnet-free fine surfaces E2 to produce and intersperse evenly, as a result of which the toner held on the cylindrical surface C at an even spacing to an even accumulated amount in perpendicular form with respect to the fine surfaces E and the intended object is thus achieved.

Title: Fixing device for shaft sealing device of oil-free screw compressor
Inventor: MORI HIDETOMO
IPC: F04C27/00
Filed: 1982-09-17
Abstract: PURPOSE:To eliminate the need for providing high accuracy in the distance between the snap-ring groove and the side of a casing and enable low-cost machining by inserting a spring device between said side of the casing and a shaft sealing and pressing said shaft sealing device to a snap ring provided on the bearing side. CONSTITUTION:A spring device (e.g., a wave-ring spring 41) is inserted between the side 38 of a casing and a shaft sealing device 8d so that the shaft sealing device 8d is pressed toward a snap ring 47 provided on the bearing 6 side. Spacers 36 and 37, and an oil thrower device 42 are pressed against the snap ring 47 due to the force of the wave-ring spring 41, whose pressing force should be such that the shaft sealing device 8d does not move in the axial direction even if pressure fluctuation of several kg/cm<2> occurs. Because of such construction, the spacers 36 and 37 and the oil thrower 42 neither the distance between a snap-ring groove 34 and the side 38 are not required to have very high machining accuracy in the axial direction, thereby reducing the machining cost.
