    摘要: An image forming apparatus for electrostatically transferring a latent image formed on a photoconductive drum or similar image carrier to a recording medium held by a clamp drum or similar medium conveying member. The clamp drum has a cylinder or base made of aluminum, a conductive rubber layer covering the cylinder, and an overcoat layer covering the rubber layer and higher in electric resistance than the rubber layer. A bias voltage for latent image transfer is applied while the rubber layer is connected to ground. The photoconductive drum and clamp drum are pressed against each other by a predetermined force, the former following the rotation of the latter. The photoconductive drum is provided with a photoconductor having a great electrostatic capacity, thereby preventing the effective transfer voltage at the time of image transfer from increasing.

    摘要: A developing apparatus using a liquid developer and a developing head located to face a path along which a recording medium carrying, for example, an electrostatic latent image thereon is transported. A groove is formed in the surface of the head that faces the transport path. After development, the liquid remaining at the corner defined by the upper inner portion of the groove and the medium is rapidly collected to allow a minimum of smear to occur on the part of the medium which will be transported later. When the transport of the medium should be interrupted during development due to, for example, a jam, the liquid in the groove is collected to prevent a great amount of liquid which would smear a drive roller and other transport members from being transferred from the head to the medium.

    摘要: The present invention provides a process for coloring titanium, or its alloys which comprises the steps of anodizing titanium metal, or its alloy in an electrolytic solution until the voltage reaches a predetermined voltage at a constant current temporarily cutting off the current supply to interrupt the anodizing; and then supplying a direct current again at a predetermined current density to continue anodizing, wherein the color tone of the anodic oxide film formed on the titanium or its alloy is adjusted by controlling the supplied amount of current, without causing an increase in voltage. By the coloring process of the present invention, the color of titanium metal or its alloys can be changed to various color tones at low voltages.

    摘要: Selenium is recovered from combustion waste gas, especially the combustion waste gas evolved from glass melting furnaces by a process in which the waste gas is contacted with an absorbing solution containing an alkali metal sulfite or bisulfite, whereby metallic selenium and selenium compounds are absorbed, the temperature of the waste gas is decreased and the humidity of the waste gas is increased. The treated waste gas in then passed through a moist glass fiber filter which collects the remaining amounts of selenium from the waste gas. The absorbing solution is combined with the solution used to wash the glass fiber filter and the combined solutions are treated with an acid which reduces all of the selenium present in the solution to metallic selenium which precipitates from solution.

    摘要: A process is described for the removal of oxides of sulfur, dust and mist from a combustion waste gas such as the waste gas evolved from a glass melting furnace in which the waste gas is contacted with an absorbing solution containing an alkaline absorbent such as NaOH, Na.sub.2 CO.sub.3 or Na.sub.2 SO.sub.3, whereby the oxides of sulfur are absorbed and the temperature of the waste gas is decreased and the humidity of the waste gas in increased. The treated waste gas is then passed through a glass fiber filter which is maintained under moist conditions in order to efficiently remove dust and mist particles from the waste gas. Crystalline sodium sulfate hydrate is recovered from the absorbing solution contacted with the waste gas.
