Abstract:
A task processing apparatus includes a main CPU, a plurality of sub-CPUs, a first starting section, a second starting section, and a notification section. The plurality of sub-CPUs independently execute a series of difference tasks set in advance in accordance with a predetermined sequence. The first starting section is arranged in the main CPU to output a first starting signal for starting the first sub-CPU, of the plurality of sub-CPUs, which executes a first task at the start of the series of tasks. The second starting section is arranged in each of the sub-CPUs except for the last sub-CPU. When the task in a given sub-CPU is completed, the second starting section outputs a second starting signal for starting the next sub-CPU which executes the next task. The notification section is arranged in the last sub-CPU of the plurality of sub-CPUs. The notification section supplies a processing completion signal indicating completion of the series of tasks to the main CPU when the last task is completed.
Abstract:
A method and a device for bending a metal hollow thick walled member to a predetermined angle without deviation of the bending center position and without separation from a half die when presser die moves up. With a pair of guide plates (GP1 and GP2) turnably attached to a center pin CP kept horizontal and the axis center of the center pin intersecting with the axis center of the metal hollow thick walled member PM, the member PM is mounted on a half die (82a). When die holding members (80a and 80b) fixedly connected to the above guide plates and kept horizontal are inclined and separated from each other as the center pin lowers, the member PM is bent to the predetermined angle and held on the half die (82b). When the center pin that can be moved vertically by a guide member moves down to a predetermined position, a contact portion (96b) contacts the inclined surface of a stopper (92b) to allow a base plate (16) to receive a pressing force from an upper die via the stopper.

Abstract:
A magnetic recording has very low warp characteristics but excellent film characteristics. Particularly, the recording medium has a high coercivity with a small range of coercivity distribution, with a warp characteristic below 3 .mu.m per radial inch. The medium is formed by heating a substrate at a high temperature with a temperature distribution on the substrate that is improved by the use of a heat distribution mask, which reduces the temperature distribution of the substrate to below .+-.3%.
Abstract:
A magnetic recording medium for longitudinal recording uses a non-magnetic substrate made of glass ceramics that is suitable for high density recording with low noise. The magnetic recording medium is obtained by forming a magnetic recording film mainly containing cobalt on a non-magnetic glass substrate through a non-magnetic underlaying film made of Cr. Further a non-magnetic covering film is formed thereon. With respect to the crystal orientation of the faces of cobalt measured by X-ray diffraction, the diffraction intensity of the (0002) face is 1.5 times or more and 8 times or less the total diffraction intensities of the other faces.
Abstract:
A card loading device includes an elevator, a roller, a card loading port, and two sensors for detecting the feeding of cards, exhausting the feeding of cards and the reloading of cards. The elevator raises/lowers a plurality of accumulated cards. The roller is arranged at a card feed position and rotated clockwise to feed a card located at an uppermost position of the accumulated cards and brought into contact with the roller when the elevator is raised. The card loading port has an opening slightly larger than a thickness of a card and loads a card fed by the roller. The two sensors can detect the proper and the improper loading of a fed card at the card loading port. When a card has been improperly loaded, the sensors send a signal that reverses the roller direction (counterclockwise) and lowers the elevator, thereby exhausting the card from the card loading port. When the card loading port is empty, the sensors send another signal, again reversing the roller direction (clockwise) and raising the elevator, thus reloading the cards into the loading port.
Abstract:
A card convey device includes a first convey path, a second convey path, a third convey path, jam detector, convey controller, and card sorter. The first convey path conveys a loaded card. The second convey path is branched from the first convey path and conveys a non-defective card distributed from cards conveyed from the first convey path. The third convey path is branched from the first convey path and conveys a defective card distributed from the cards conveyed from the first convey path. The jam detector detects jam of a card occurring in each of the first, second, and third convey paths. The convey controller conveys a card through each of the first, second, and third convey paths at a predetermined speed, stops a convey operation of the card when the jam detector detects jam of the card, and reconveys the card in response to a reconvey command. The card sorter distributes the card conveyed from the first convey path to one of the first and second convey paths on the basis of non-defective/defective information of the card, and forcibly distributes a reconveyed card from the first convey path to the third convey path.
