| 20100292542 | ARM STRUCTURE AND HOLDING DEVICE FOR SURGICAL INSTRUMENT - An arm structure includes: a pair of arms; a support post; a support member; a cam provided in one of the pair of arms; a shaft member inserted through a lateral insertion hole of the support member; and a pair of ring-shaped members provided in end portions of the shaft member, wherein by turning the one of the arms around its axis thereby to make the cam revolve, a force works to make the shaft member move, and due to its reaction force the ring-shaped members pressure-contact the support member and a slit portion is narrowed. As a result, a longitudinal insertion hole is diameter-reduced and becomes in a state of pressure-contacting the support post, leading to restriction of rotation of the arm around the support post, and the cam pressure contacts the one of the arms, leading to restriction of sliding of the arm in a long side direction, and the ring-shaped members pressure-contact the support member, leading to restriction of rotation of the arm by the shaft member. | 11-18-2010 |

| 20090053021 | Semiconductor manufacturing apparatus - A semiconductor manufacturing apparatus comprises a substrate transfer device for transferring a substrate, a substrate detector unit including a light emitter unit for emitting light onto the substrate and a light receiver unit for receiving the light to detect the substrate transferred by the substrate transfer device, and a controller for receiving data on the received light quantity from the light receiver unit. Multiple mutually non-overlapping light quantity ranges are pre-registered in the controller, and when light emitted from the light emitter unit reaches the light receiver unit by way of the substrate, the controller identifies which of the pre-registered light quantity ranges is the received light quantity, and outputs a command according to the identified light quantity range. | 02-26-2009 |

| 20110200190 | CRYPTOGRAPHY PROCESSING DEVICE AND CRYPTOGRAPHY PROCESSING METHOD - A cryptography processing device has: a round processing unit configured to obtain a processing-object data and generate an intermediate data by applying round processing to the processing-object data; a random number generation unit configured to generate a random number data; a memory circuit in which the intermediate data or the random number data is stored; and a selection control unit configured to select which one of the intermediate data and the random number data is to be stored in the memory circuit. The selection control unit selects the data to be stored in the memory circuit such that the random number data is stored after the intermediate data is stored. | 08-18-2011 |

| 20100246808 | SIDE CHANNEL ATTACK TOLERANCE EVALUATION APPARATUS, METHOD AND PROGRAM - Provided is a side channel attack tolerance evaluation device capable of evaluating the propriety of the estimation of an encryption algorism, processing timing, and determination of a processing sequence of the encryption algorism using side channel information. The side channel attack tolerance evaluation device, which performs evaluation of tolerance to a side channel attack by using side channel information leaking from an encryption device, is provided with a storage unit (character data storage device), a measurement unit (side channel information measurement device), and a processing unit (side channel attack tolerance evaluation unit). The storage unit stores side channel information that has been previously acquired by executing a predetermined encryption algorithm in an encryption device or information obtained by applying predetermined processing to the side channel information. The measurement unit measures the side channel information generated from an encryption device to be evaluated. The processing unit calculates a correlation value between the side channel information acquired by the measurement unit and character data stored in the storage unit to determine the propriety of tolerance of the encryption device to be evaluated to the side channel attack. | 09-30-2010 |
