20130176602 | LIGHT BEAM SCANNING DEVICE, IMAGE FORMING APPARATUS, AND SCANNING LINE ADJUSTING METHOD - A light beam scanning device scans a luminous flux irradiated from a light source and deflected by a deflector to a scanned surface through an optical system having a set of mirrors. A apparatus, such as the light beam scanning device, further includes a scanning line curve adjusting device to bend a first mirror of the set of mirrors so as to correct a curve in a scanning line on the scanned surface, and a scanning line tilt adjusting device to change orientation of a second mirror of the set of mirrors so as to correct a tilt in the scanning line on the scanned surface. The light beam scanning device may be provided in an image forming apparatus. | 07-11-2013 |
20130235144 | OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS - An optical device includes: a light source that emits a light beam; a deflector that deflects the light beam in a main-scanning direction; and a scanning/image-forming optical system that includes a scanning lens that causes the light beam deflected by the deflector to converge to a scanned surface to form an image on the scanned surface. The scanning lens has refractive index gradient. At least one surface of the scanning lens is a tilt-decentered surface that has a tilt angle, which depends on a position in the main-scanning direction, in a sub-scanning direction. The tilt angle is set so as to compensate for variation, which results from the refractive index gradient, in direction of the light beam in the sub-scanning direction. | 09-12-2013 |

20100162974 | WATER PUMP ATTACHMENT STRUCTURE OF WATER-COOLED INTERNAL COMBUSTION ENGINE - A water pump attachment structure of a water-cooled internal combustion engine is provided to facilitate the maintenance of a valve train. A water pump attachment structure of a water-cooled internal combustion engine includes a semicircular cut-away surface of a water pump holder opposed to a semicircular surface of a cylinder head to form a water pump support circular hole. Screw members are passed through respective screw through-holes of the cylinder head and threadedly engaged with internal thread holes of the water pump holder. Thus, the water pump holder is fastened to the cylinder head. A water pump is fitted into and secured to the water pump support circular hole. A cylinder head cover is attached to the cylinder head by allowing their mating surfaces to conform with each other with the water pump holder liquid-tightly sandwiched therebetween. | 07-01-2010 |
20110271340 | METHOD AND APPARATUS FOR DETECTING SPOOFED NETWORK TRAFFIC - A method and apparatus for detecting spoofed IP network traffic is presented. A mapping table is created to indicate correlations between IP address prefixes and AS numbers, based on routing information collected from a plurality of data sources. At each interface of a target network, IP address prefixes from a training traffic flow are acquired and further converted into AS numbers based on the mapping table. An EAS (Expected Autonomous System) table is populated by the AS numbers collected for each interface. The EAS table is used to determine if an operation traffic flow is allowed to enter the network. | 11-03-2011 |
20130125235 | Method, Apparatus and Program for Detecting Spoofed Network Traffic - A method, an apparatus and a program for detecting spoofed Internet Protocol (IP) traffic directed to a network having a plurality of autonomous systems (AS) is provided. The method comprises receiving an incoming packet through an AS, the incoming packet containing a source IP address and a destination IP address, acquiring a corresponding source and destination IP address prefixes, converting the corresponding source and destination IP address prefixes into a source AS number and a destination AS number, determining if the incoming packet arrived from an unexpected source based upon the corresponding destination IP address prefix and the converted source and destination AS number using an unexpected pair tuple table generated from network routing information and generating an alert indicating that the incoming packet is not allowed to enter the network. | 05-16-2013 |
20150304102 | NON-LINEAR PROCESSOR, STREAM-CIPHER ENCRYPTING DEVICE, STREAM-CIPHER DECRYPTING DEVICE, MASK PROCESSING METHOD, STREAM-CIPHER ENCRYPTING METHOD, STREAM-CIPHER DECRYPTING METHOD, AND PROGRAM - A non-linear processor, which subjects an input value from a feedback shift register storing an internal state of a stream cipher to non-linear processing to output a key stream, is connected to internal registers, which store output values from a non-linear substitution circuit which subjects the input value to non-linear substitution processing. The non-linear processor is provided with an exclusive-OR unit, which is at an input end of each of the internal registers and carries out an operation of a random number generated from part of values stored in the feedback shift register and the output value of the non-linear substitution circuit to mask the output value of the non-linear substitution circuit, and another exclusive-OR unit, which is provided at an output end of the internal register and performs an operation to unmask the value stored in the internal register. | 10-22-2015 |
