    摘要: The present invention provides a life detecting system that accurately detects the end of the useful life of a process unit used in electrophotographic printers. The life detecting system comprises a RAM that stores a count of the number of driving pulses generated at an exposure unit and a ROM that stores a predetermined reference count that represents the useful life of the process unit in terms of a driving pulse count. The system indicates that the end of the useful life of the process unit has been reached when it determines that the count stored in the RAM is greater than or equal to the predetermined reference count stored in the ROM.

    摘要: A non-oxidizing heating method and apparatus in which a non-oxidizing gas of high temperature is continuously generated and supplied into a furnace by changing over a plurality of heat storage type heaters alternately while repeating an operation in which one heater stores heat and the other heater heats and blows the non-oxidizing gas. Since it is possible to heat by producing a completely non-oxidizing atmosphere within the furnace, the method and apparatus can be effectively utilized in furnaces which require heating in a non-oxidizing atmosphere, for example, various furnaces such as a ladle, tundish, etc. used in a field of steel manufacturing and continuous casting, and various furnaces used in a field of heating and heat treatment of metallic materials, and thus, it is effective to achieve reduction of operational cost, improvement of product quality, and improvement of product yield.

    摘要: An image recording apparatus is provided which automatically controls the temperature and humidity in the region of a photosensitive recording medium. The recording medium carries the indication of its sensitivity characteristic. A detector disposed in the image recording apparatus reads the sensitivity characteristics which may take the form of the bar code or magnetic tape. The detector then sends an output signal, to a controller. At least one of a thermal sensor and a humidity sensor are provided in the passage of the photosensitive recording medium. These elements respectively sense the temperature and humidity and output their detection signals to the controller. The controller then controls a heater and a humidifier to set the optimal temperature and optimal humidity for the passage.

    摘要: A tracking servo device for changing a position on an optical storage disk, at which the storage disk is irradiated by a light beam. The servo device is responsive to a tracking error signal indicative of a deviation of the irradiated position on the disk with respect to a recording track provided on the disk. The tracking servo device includes an optical deflector element having a waveguide disposed in a path of the light beam, for guiding the light beam therethrough toward a surface of the optical storage disk, so as to deflect the light beam during propagation thereof through the waveguide. The device further has a deflection control arrangement for controlling an angle of deflection of the light beam by the optical deflector element, based on the tracking error signal.

    摘要: In an optical printing system for printing an image on a recording sheet, adopted as the recording sheet is a sheet coated with microcapsules on one surface thereof. Each microcapsule envelopes a first component which changes color when reacts with a second component. The second component may be coated on the recording sheet or may be coated on a separate developing sheet. The microcapsule further envelopes a third component which varies the mechanical strength of microcapsule when light is projected thereto. An image is formed on the recording sheet by selectively exposing a light thereto in accordance with the image to be printed thereon, and the microcapsules on the recording sheet whose mechanical strength is low are then ruptured by rupturing means. Thereby, the color is developed or the recording sheet on the separate developing sheet by the reaction of the first component with the second component.

    摘要: The casting apparatus for a hollow steel ingot is constructed such that: at least three concentric pipes are provided in the central portion of an ordinary mold for a steel ingot; a core is formed by filling up a space formed between the first outer-most pipe having the largest diameter and the second pipe disposed inwardly of the first pipe with granular refractory material wherein zircon or chromite sand is bound by a binder such as an organic resin; a double pipe is disposed inwardly of said core and forming a gas flow course for cooling the core; and pouring gates formed through the stool for feeding molten steel at an intermediate portion between the inner wall of said mold and the core. The method for producing a hollow steel ingot by use of the casting apparatus as described above comprises: blowing the cooling gas from above into the third inner-most pipe having the least diameter, passing the gas through the second pipe from below and discharging it to above; cooling the molten steel fed into the mold and brought into contact with the outer surface of the first pipe by cooling the core through the inner wall of the second pipe; and controlling the cooling conditions for the core such as the thickness of the cylindrical refractory material of the core, the cross-sectional area of the cooling gas flow course and the thickness of the second pipe so that the finally solidifying position of the molten steel fed can be set at a position which is apart from the core side at a distance of 20 to 50% of the wall thickness of the hollow steel ingot to be formed.
