  • Publication number: 20140284195
    Abstract: A switch has a normally-closed fixed contact unit, a common contact unit, a pressing member, and a movable contact that is attached to the pressing member, and that slides on the normally-closed fixed contact unit and the common contact unit. A conductive region and an insulating region are formed on a sliding surface of the movable contact in the normally-closed fixed contact unit in order toward a pressing direction of the pressing member. A conductive region and an insulating region are formed on a sliding surface of the movable contact in the common contact unit in order toward the pressing direction. The movable contact slides from the conductive regions to the insulating regions to switch from a closed state to an opened state.

  • Publication number: 20140240752
    Abstract: An image forming apparatus includes: a motor unit configured to give a rotary drive force to rotary members for conveying a recording medium; a switch circuit provided in a power supply line connecting a power source and the motor unit to supply electric power, connecting the motor unit to the power source upon closure of the body cover, and disconnecting the motor unit from the power source upon opening of the body cover; a power-off detecting section; a rate-of-voltage-change calculating section; and a control section. The control section deactivates each of mechanisms in the image forming apparatus when the power-off detecting section detects shutoff of power supply from the power source, and reactivates each of the mechanisms, provided that the rate of change of voltage calculated by the rate-of-voltage-change calculating section has reached a predetermined threshold, when the power-off detecting section detects electric power is supplied from the power source.

  • Publication number: 20140240804
    Abstract: An image reading apparatus includes a document table, an image reading portion, a cover member, a reading control portion, and a document determination portion. On a color reference surface of the cover member which opposes to a document table, a partial region is provided which has a predetermined density different from a density of the color reference surface. The reading control portion reads image data from the color reference surface and the partial region of the cover member by the image reading portion. When a density difference between a density of the color reference surface and a density of the partial region on the image data read by the reading control portion is equal to or smaller than a predetermined threshold value, the document determination portion determines that the document placed on the document placement surface is a book document.

  • Publication number: 20140136485
    Abstract: [Problem] To provide a file management system and file management method that are able to perform a backup process efficiently by means of a configuration that uses a virtual file system metadatabase from a backup process side also. [Solution] The file management system is provided with a virtual drive controller (110) that controls a virtual drive (5), a metadatabase (210) that contains information for associating a virtual file and a physical file that is saved in a storage device (6), a backup controller (120) that manages the backup process of a file, and a backup status management database (220) used in backup process management. The virtual drive controller (110) registers updated file information in the backup status management database (220). The backup controller (120) references the backup status management database (220) and the metadatabase (210), and backs up the file.

  • Patent number: 8717027
    Abstract: Apparatuses, methods, and other embodiments associated with determining organ viability are described. According to one embodiment, an apparatus includes logic configured to apply nuclear magnetic resonance (NMR) energy to a kidney positioned in a hypothermic pulsative perfusion (HPP) apparatus. The NMR energy is produced according to an MRS 31P specific pulse sequence. The HPP apparatus has an integrated RF coil. The HPP may also have an integrated magnet. The RF coil is positioned and oriented to facilitate optimizing 31P MRS of the kidney. The apparatus also includes logic configured to receive spectrum data from the kidney. The spectrum data is produced in response to applying the NMR energy to the kidney. The apparatus also includes logic configured to provide objective, quantitative kidney viability data (e.g., PME/Pi, ATP/ADP) from the spectrum data. More generally, MRI/MRS compatible HPP apparatuses are configured to interact with dedicated NMR spectroscopy apparatuses.

  • Publication number: 20140120631
    Abstract: A protein detection device and method. The device has a main channel in which is attached either a polar rail molecule or a biomolecular motor which moves on the rail molecule in a direction corresponding to the polarity of the rail molecule. A sub-channel crosses the main channel for receiving a sample including tau-protein. The method includes feeding the sample to the device and detecting a ratio of mutated tau-protein included in the sample, based on motion of the biomolecular motor on the rail molecule or on motion of the rail molecule moved by action of the biomolecular motor.

  • Publication number: 20130273788
    Abstract: The present invention is to provide a terminal capable of being reduced in size and a connecting holder of the same. The terminals protrude from a housing, and include a branch portion, a terminal section cut out from the branch portion toward a tip end of the terminal section in a longitudinal direction, and a bent portion adjacent to the tip end. By decreasing a distance from the bent portion to a tip end of the terminal, variations in length size to the tip end due to bending can be suppressed.
