  • Patent number: 6135384
    Abstract: A device has a pivoted lever for detecting a near end state of a roll of paper, and the lever is held at a first position by the weight of a roll of paper, but is resiliently biased toward a second position by a spring. When the roll of paper does not have a core, and when the weight thereof falls to a predetermined value, the lever is moved from the first position to the second position due to a resilient force of the spring. When the roll of paper has a core, and when a diameter thereof is reduced to a predetermined value, the lever receives the roll of paper in a recess formed therein, and is moved from the first position to the second position due to a resilient force of the spring. When the lever is moved to the second position, this is detected by a suitable detecting element. Thus, the detector can detect the near end state of the roll of paper without regard to whether the roll of paper has a core or not.

  • Patent number: 5371887
    Abstract: A time-shared multitask execution device processes two or more tasks in time-shared manner by using one CPU. A common set of a control register group and a queue selection control part are provided for plural task execution queue for executing plural tasks. Under the control of the control register group and queue selection control part, one CPU is occupied by the plural task execution queues in a time-shared manner, so that the plural tasks may be processed concurrently. The user has only to set the information necessary for the register in the control register group according to the user's specification, and the task execution specification can be determined. Therefore, even in the case of a user with a limited knowledge about the program, the desired specification can be set only by setting a flag bit of information to 1 or 0 in a register which is a part of the "hardware".

  • Patent number: 5339132
    Abstract: A light emitting element array in an electronic photographing apparatus, in which a photoconductor drum is exposed to a light from a light emitting array having a plurality of light emitting diodes to form a latent image on the drum, and a high quality, stable light image can be deposited on the photoconductor drum from a light emitting array, even after extended use. The constitution is such that a fixed bracket 31 is fixedly mounted on the electronic photographing apparatus, a rotatable bracket 33 is rotatably mounted on the fixed bracket and fixedly secured to the light emitting element array 2, a bias means 37 urges the light emitting element array 2 against the outer surface of the photoconductor drum 1, a space keeping means 38 is pushed by the bias means against the outer surface of the photoconductor drum so as to maintain a constant distance between the light emitting element array and the outer surface of the photoconductor drum 1.

  • Patent number: 4414077
    Abstract: The invention comprises an improved method for producing anodized aluminum articles colored by means of optical interference effects. The method comprises the steps of subjecting an aluminum article that has been anodized by conventional process to a treatment for modifying the pore structure of the anodic film, thereafter subjecting it while connected as anode to an electrolytic treatment for modifying the barrier layer between the oxide and the metal substrate and finally coloring the article while connected as cathode in an electrolyic bath containing one or more dissolved metal salts using DC current on which is superimposed a train of positive current pulses.

  • Patent number: 4316780
    Abstract: Disclosed is a method of coloring an anodized and anodically reinforced aluminum or aluminum alloy article by cathodic treatment in a coloring solution wherein the cathodic electrolytic current is a negative voltage direct current having a duration substantially less than the interval therebetween and being repeated at a frequency sufficient to produce the required coloration.
