摘要:
A developing device using a one-component developer or toner and applicable to image forming equipment for supplying the developer to a photoconductive element disposed above the device. The device supplies a desired amount of toner to a toner supply roller and a developing roller at all times with no regard to the position thereof, thereby insuring stable images. Further, the device enhances free layout of the equipment and occupies a minimum of sectional area relative to the photoconductive element.

A method for generating an underliquid shock pressure comprises the steps of igniting a combustible mixture gas to form detonation waves, imploding the detonation waves in their advancing direction, propagating a pressure obtained by imploding the detonation waves to a liquid, and converting the pressure to an underliquid pressure which is applied to a workpiece. The pressure obtained by imploding the detonation waves may be applied directly to an elastic rubber body, thus converting the pressure to an underelastomer shock pressure, which is then applied to the workpiece via the elastic body. An apparatus for generating an underliquid shock pressure comprises a combustion chamber whose cross-sectional area decreases from one end toward the other end of the chamber, an ignition chamber to which fuel is fed and in which a spark plug is positioned, a plurality of guidance paths extending from the ignition chamber and communicating with one end of the combustion chamber, each of the guidance paths having substantially the same length, and a pressure medium chamber connected to an opening of the other end of the combusiton chamber having the smallest cross-sectional area. The pressure at the smallest cross-sectional area end of the combustion chamber is applied to a liquid to convert the pressure into underliquid shock pressure, which is then applied to a workpiece either directly or via an elastic body interposed between the liquid and the workpiece.
摘要:
The invention relates to a fuel electrode for high-temperature solid electrolyte fuel cells and a process for manufacture of the electrode. The fuel electrode of the invention is a porous element composed of a high-melting metal, such as ruthenium, osmium, rhodium or iridium, or an alloy containing the metal. The process for manufacture of the fuel electrode comprises coating an electrode material with a solution or dispersion of the high-melting metal and/or its chloride, sintering the same and finally reducing the product.

摘要:
A developing unit usable with and removably mounted on a copier, printer, facsimile machine or similar image recording apparatus. When the developing unit reaches the end of a predetermined service life thereof as counted in terms of, for example, the number of times that a toner end condition has occurred, it is prevented from being loaded again on the body of the image recording apparatus and, at the same time, the user is clearly informed of the time for replacement of the developing unit.
摘要:
An illumination device comprising a reflecting plate, a single or a plural number of linear light source(s) arranged over said reflecting plate and a diffusing plate arranged over said light source(s), a light quantity adjusting means being arranged on the surface of the linear light source on between said light source(s) and said diffusing plate, and said illumination device being so adapted as to uniformalize luminance distribution on the diffusing plate by selecting shape and size of light-transmitting portions of the light quantity adjusting means.
摘要:
A microprocessor including a CPU, an instruction memory (ROM) with a sequencer in the CPU that sends out a fetch signal for an instruction, and an address decoder that decodes the fetch signal and sends a signal to the ROM allowing the fetch signal to fetch an instruction if the address is correct.
摘要:
A structure of an electromagnetic valve for opening and closing a passage of a fluid flow which is applicable to a air suspension system of a vehicle. The electromagnetic valve includes a plunger linked with an armature, a first valve attached to the plunger for defining a first chamber and a second chamber in a body of the electromagnetic valve, together with a valve seating member installed within the body, a second valve attached to the plunger for opening and closing the fluid flow passage opened to the first chamber, and a spring for biasing the plunger in an open direction of the first valve and second valve, a second fluid flow passage being opened to the first chamber for introducing the fluid from the first fluid flow passage, a fluid pressure in the fluid passage being introduced to the second chamber via another passage, and an effective pressure applied area of the first valve (A2) being substantially equal to that (A1) of the second valve. A noise extinguishing projection in a substantially letter Y shape is installed on a valve seating portion of the valve seating member. In addition, the second valve is spirally engaged with the plunger and a spring receiving member for receiving one end of the spring functions as a lock nut of the second valve.
摘要:
A color separating optical apparatus is provided with a compensating members in order to compensate for the differences in output energy of the separated colors which is attributable to the particular spectral characteristics of the light source and the light receiver. In various embodiments, selectable masks are used to control the light flux, or the light source itself is controlled as to the number of lamps energized for each color.
摘要:
A color copying apparatus which comprises: a latent image forming device for forming a latent image of a figure to be printed; an image forming medium on which the latent image is formed; a plurality of development devices for developing the latent image formed on the image forming medium by a different color toner, respectively; and an endless conveyor belt spanning between two rollers and for carrying a transfer material to which the developed colored toner image is transferred from the image forming medium. The copying apparatus is featured to comprise a first shifting system for shifting a whole of the conveyor belt close to and away from the image forming medium and a second shifting system for shifting a part of the conveyor belt close to and away from the image forming medium at a position where the toner image is transferred from the image forming medium to the transfer material. In accordance with the featured structure of the present invention, it becomes possible to slightly shift the conveyor belt away from the image forming medium in the copying operation, while in the maintenance operation it is possible to shift the conveyor belt sufficiently away from the image forming medium for facilitating the maintenance operation.
