摘要:
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. The bend extends substantially the full width between the outer and intermediate plates when chain tension is generated.

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.

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.

Methacrylimide-containing polymers are continuously produced by introducing 10 to 60 wt. % of an inert solvent, 90 to 40 wt. % of methacrylic acid, a methacrylic acid ester or a monomer mixture comprising at least 50 wt. % of methacrylic acid or a methacrylic acid ester, and a radical polymerization initiator and a molecular weight modifier into a polymerization reaction zone, converting at least 80 wt. % of the charged monomer to a polymer at 60.degree.-170.degree. C., adding a compound represented by the formula:R--NH.sub.2wherein R represents a hydrogen atom, an alkyl group having 1-12 carbon atoms, a cycloalkyl group having 7-11 carbon atoms or an aryl group having 6-10 carbon atoms,to the polymerization reaction liquid, carrying out reaction of the resulting mixture at 150.degree. to 300.degree. C. in an imidization reaction zone, and finally separating volatile substances from the reaction fluid.

A piezoelectric oscillator is provided with a container unit in which an upper cavity and a lower cavity are partitioned by a partition wall, a piezoelectric oscillating element accommodated in the upper cavity, an IC chip and electronic components accommodated in the lower cavity and forming an oscillating circuit, and external terminals provided at the periphery of the bottom surface of the container unit and connected with the oscillating circuit. A jitter reducing structure for reducing jitter components of an oscillation wave outputted from the output terminal which is an external terminal electrode is formed in the partition wall of the container unit. There can be provided a small-size piezoelectric oscillator which has an excellent jitter characteristic of an oscillation waveform and can stably and satisfactorily perform high-frequency oscillation utilizing overtone oscillation, and whose characteristic is easily changeable to provide excellent versatility and noise resistance.

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.

A chain includes a plurality of link assemblies connected with each other. One of the adjacent link assemblies has a first pair of plates disposed apart in the direction perpendicular to the longitudinal direction of the chain and a pair of hollow cylindrical bushes press-fitted to the first pair of plates. The other of the adjacent link assemblies has a second pair of plates disposed apart in the direction perpendicular to the longitudinal direction of the chain so as to locate at the outside of the first pair of plates and a pin penetrated through the bush and press-fitted to the second pair of plates. A moisture absorption member which retains lubricant oil between the bush and the pin is placed between facing surfaces of the first and second plates. The moisture absorption member has a large deformation amount and a small restoration amount.

C. or higher and a weight-average molecular weight of 10,000 to 500,000 in a substantially slurry state.
摘要:
A frictional transmission chain drive for use between V-groove pulleys comprises a series of C-shaped chain struts and friction force struts superposed along the length of an endless transmission chain. The chain struts are fitted in grooves located across link plates of the chain, with their open ends alternately located on opposite sides of the transmission chain. The friction force struts are provided with recesses which grip the chain to prevent sideways movement of the struts relative to the chain. The friction force struts on opposite sides of a chain strut can have their open ends on the same said of the chain as the open end of the chain strut, or, alternatively, can have their open ends on the side of the chain opposite the side on which the open end of the chain strut is located.
