Abstract: An operation input device includes a base including at least four elastic engagement receiving portions raised at a periphery of a center thereof; a print substrate configured to be stacked and integrated on the base; an annular operation plate mounted on push button switches of the print substrate and configured to prevent slip-out; an operation dial mounted on the annular operation plate on an axial center; and a fixing tool configured to be inserted to a fit-in hole of the operation hole and engage with at least two elastic engagement receiving portions of the base at an edge on a lower side and with an inner peripheral edge of the operation dial.

Abstract: A transmitting multi-row chain having easy disassembling or assembling such as dismounting or mounting a chain on its sprockets and, when even high load chain tension is applied, the high load is dispersed to each inner plate so that the load balance in the chain width direction is improved. A transmitting multi-row chain in which inner link units each comprising inner plates into which bushes are press-fitted are coupled in parallel with each other through intermediate plates in a width direction of the chain. The coupled inner link units are connected to each other in a large number by connecting pins having a diameter smaller than the diameters of the pin holes of the intermediate plate. The connecting pin is inserted into the pin hole 121 of the intermediate plate whose pitch between pin holes is narrower than the pitch between pin holes of the outer plate, the pin having a medial bend directed toward the pitch zone of the outer link in a state where chain tension is not generated.

Abstract: An image determination apparatus is provided which obtains a first image which is picked up by illuminating the subject of image pickup from a first position and a second image which is picked up by illuminating the subject of image pickup from a second position. The image determination apparatus determines whether or not the subject of image pickup is a living body from a change in shading on the first picked up image and the second picked up image. Further, an individual authentication apparatus that includes an image pickup unit and a control unit determines whether a subject is a living body from a change in shading on a first picked up image and a second picked up image. If the subject is a living body, an authentication function is initiated using a third picked up image, the authentication function determining whether or not to authorize the subject.

Abstract: An object of the present invention is to urge a user to check a target to be checked by the user. A check condition detecting section 104 detects whether or not a user has checked a to-be-checked target to be checked by the user which is identified by a to-be-checked target identifying section 101, on the basis of the direction of the user's face detected by a face direction detecting section 102 or the direction of the user's line of sight detected by a line-of-sight direction detecting section 103. A notification control section 105 controls a notifying section so that if the user has not checked the to-be-checked target, it notifies the user of a situation requiring the user to check the to-be-checked target and so that if the user has checked the to-be-checked target, it limits the notification of the situation requiring the user to check the to-be-checked target. The present invention can be applied to the monitoring apparatus for monitoring the car speed.

Abstract: An image determination apparatus is provided which can determine whether a subject of image pickup is a living body or a nonliving body such as a photograph of a face or a print on which a face is printed. An individual authentication apparatus obtains a right direction illumination image which is picked up by illuminating the subject of image pickup from its right side and a left direction illumination image which is picked up by illuminating the subject of image pickup from its left side. In the case in which the subject of image pickup is a living body, a left side is shaded in the right direction illumination image and, on the contrary, a right side is shaded in the left direction illumination image due to unevenness such as a nose and eyes.

Abstract: A roller chain includes a sintered oil-impregnated bushing loosely fitted coaxially on a connection pin for outer plates, a roller fitted for rotation on and around the sintered oil-impregnated bushing, and a needle roller bearing interposed between the sintered oil-impregnated bushing and the roller and having grease charged therein. Lubricant of the sintered oil-impregnated bushing side and the grease of the needle roller bearing side supplement oil components to each other and the overall amounts of the grease and the lubricant of the roller chain can be effectively utilized to allow the roller chain to be used without supplement lubricant for a long period of time. Thus, the roller chain can suppresses a local out-of-oil condition and make effective use of the overall amount of available oil components of grease to assure a reduced frictional resistance upon running of the roller chain for a long period of time thereby to exhibit a superior abrasion resistance and durability.
