Abstract: A solution supply comprises a container having a space and a channel socket in the space to allow the solution to flow out of the container, the container floated by buoyance in a water tank and a feeder opening or closing the channel socket by buoyance and gravity in the water tank, wherein the feeder includes a dispenser having an upper portion and a lower portion, and wherein the upper portion of the dispenser includes a coupling body having an upper portion assembled with the channel socket along the same axis as the channel socket and moved by the buoyance of the container, and the lower portion of the dispenser includes a weight center base supporting the coupling body and a shutter stem coupled with an upper portion of the weight center base and having a stem seal for opening and closing to the channel socket.

Abstract: Method of fixing toner by applying a fixing agent to a substrate containing an unfused toner at predetermined positions thereof, by spraying or dripping the fixing agent onto the substrate, or immersing the back surface of the substrate into the fixing agent to permit the fixing agent to permeate into the other side of the substrate containing the toner. The fixing agent causes the unfused toner to be half-dissolved or swollen on the surface of the object and the half-dissolved or swollen toner is dried to be fixed to the substrate.

Abstract: In an apparatus for conveying dielectric sheets used in copying machines, etc., sheets are held by electrostatic adhesion on the surface of a conveyor when such surface is electrically charged and thus conveyed by the conveyor, wherein a dielectric layer consisting of a dielectric material and electrode parts consisting of a conductive material, which are electrically connected to portions of the dielectric layer and grounded, are provided adjacent to each other on an adhesion surface of the conveyor.

Abstract: An electrostatic charge emitting apparatus includes a discharging member having an electrode member, an electrically conductive elastic rubber member having fine conductive particles contained therein and an insulating layer having a number of apertures therein and being formed on the conductive elastic rubber member; and the electrode member is connected to an electric power source and a surface of the insulating layer is urged against a member to be charged or de-charged: and the member to be charged or de-charged is charged or de-charged by discharge in the apertures of the insulating layer generated by emitting electrostatic charge toward the member at a lower threshold voltage and thus the generation of ozone gas can be decreased.
