| 20100149684 | DATA-STORAGE DEVICE AND ANALYSIS METHOD FOR DATA-STORAGE DEVICE - A data-storage device with a security function for user data stored in a data-storage medium. The data-storage device includes: the data-storage medium for storing data; an authentication processing section for performing an authentication process with a key obtained from a host; an error correction circuit for performing error correction in reading data at an address designated by a read command from a host which has been recognized as an authorized user for analysis access by the authentication processing section; and an analysis processing section for generating data indicating the positions of the error correction and transferring the data to the host. | 06-17-2010 |
| 20110058230 | OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS - An oscillating mirror module as a deflecting unit is disposed so that a movable mirror faces a plane where image carriers are arranged. A plurality of light source units are disposed within a plane parallel to the plane where the image carriers are arranged so that main light fluxes of light beams emitted from the light sources form predetermined angles with each other. The oscillating mirror module includes an incidence mirror that bends a plurality of light beams emitted from the light source units to direct the light beams to the movable mirror, and a separation mirror that separates the light beams scanned by the movable mirror into two opposite directions with respect to a cross-section including a surface normal of the movable mirror and perpendicular to the rotation axis of the movable mirror. A light collecting unit collects light beams so that output optical axes of the light beams corresponding to the light source units intersect on a surface of the movable mirror of the deflecting unit. | 03-10-2011 |

| 20090050510 | Structure for Air-Packing Device - An air-packing device has an improved shock absorbing capability to protect a product in a container box. The air-packing device is comprised of first and second thermoplastic films where predetermined portions are bonded thereby creating a plurality of air containers, a plurality of heat-seal lands each sealing the first and second thermoplastic films in a small area of the air container thereby creating a plurality of series connected air cells for each air container, a plurality of check valves for corresponding air containers for allowing the compressed air to flow in a forward direction. The plurality of heat-seal lands at predetermined sides of the air-packing device create triangled areas of the air cells, and the air-packing device is folded at the heat-seal lands, thereby creating an inner space for packing a product therein. | 02-26-2009 |
| 20090091122 | PERSONAL INFORMATION PROTECTING SHEET, METHOD OF MANUFACTURING THE SAME, AND ENVELOPE WITH PERSONAL INFORMATION PROTECTING SHEET - The present invention provides a personal information protecting sheet in which personal information can be easily made illegible. The personal information protecting sheet includes a base material, a release layer formed on at least a part of the surface of the base material, and an image-receiving layer formed on the release layer. When a force having a directional component that is larger than a predetermined value and parallel to the surface of the base material is applied to the surface, a portion of the image-receiving layer to which the force is applied is peeled from the release layer. | 04-09-2009 |
| 20100072875 | SURFACE EMISSION TYPE ELECTRON SOURCE AND DRAWING DEVICE - A surface emission type electron source according to the present invention includes a first electrode having a planar form; a second electrode having a planar form facing the first electrode; an electron passage layer disposed between the first electrode and the second electrode; and a power source part configured to apply a voltage to the second electrode and the first electrode. The electron passage layer includes plural quantum wires extending in a first direction from the first electrode to the second electrode. The quantum wires are spaced apart from each other at predetermined intervals, and electrons are emitted from a front surface of the second electrode. The quantum wires are made of silicon, and each of the quantum wires has plural thin parts having small thicknesses formed at predetermined intervals along the first direction. | 03-25-2010 |
