摘要： A developer-remaining-amount notifying device for notifying a remaining amount of a developer accommodated in a developer accommodating unit and used for developing a latent image formed on an electrophotographic photosensitive member is provided. The device includes a position detection member positionable near an upper surface of an accumulated layer of the developer accommodated in the developer accommodating unit, a regulating member, and a notification device. The regulating member regulates a moving direction of the position detection member such that the position detection member moves substantially linearly in accordance with a gradual decrease of the developer accommodated in the developer accommodating unit as the developer is used for development. The notification device notifies a remaining amount of the developer accommodated in the developer accommodating unit in accordance with a position of the position detection member.

摘要： There are provided a CPU connection circuit and a method wherein the CPU connection circuit is a circuit to be employed by two CPUs by alternately conducting a changeover between two buffers disposed therebetween to prevent an event that data processing cannot be fully executed by the CPU on the receiving side. There is included a memory controller 303 which monitors whether or not an amount of data stored by a CCPU 1 in either one of buffers 301 and 302 reaches a predetermined threshold value; when the amount of data stored by the CCPU 1 in the buffer 301, 302 reaches the threshold value, the memory controller 303 requests an ACPU 2 to acquire the data stored in the buffer and changes the storage destination of data from the CCPU to the other one of the buffers; the threshold value is a value more than a unit quantity of data which the CCPU 1 sends to the buffer 301, 302.

摘要： A fiber-composite material (7) is comprised of a yarn aggregate (6) in which yam (2A, 2B) including at least a bundle (3) of carbon fiber and a carbon component other than carbon fiber is three-dimensionally combined and integrally formed without separation from each other; and a matrix made of Si—SiC-based materials (4A, 4B, 5A, 5B) filled between the yarn (2A, 2B) adjacent to each other within the yarn aggregate (6). A method of preparing fiber-composite material is comprised of the steps of: producing bundles (3) of carbon fiber by impregnating a component of powdery carbon into the bundles (3) of carbon fiber, which eventually forms a matrix shape; forming a plastic coat around the bundles (3) of carbon fiber to obtain an intermediate material; molding the intermediate material to obtain a molded product by making the intermediate material into a yarn-shape and laminating a predetermined amount of the material, or burning the molded product to obtain a burned product; holding the molded product or the burned product and Si, at 1100 to 1400° C. in an atmosphere of inert gas; and heating the molded product or the burned product and Si to a temperature from 1450 to 2500° C., to thereby impregnate Si—SiC-based material into the inside of pores of the molded product or the burned product. A light and strong composite material is provided, which has excellent shock resistance, corrosion resistance in a strong oxidation and corrosion environments, creep resistance, spalling resistance, wear resistance, a low friction coefficient and a self-restorative ability by which a defect is healed.
