Abstract: A cable protection and guide device in which maintenance of cables is easily performed without completely removing a cable accommodating space extension arm from a side plate is disclosed. Inadvertent disengagement of the cable accommodating space extension arm is prevented because the arm strongly engages the side plates of the device. The cable protection and guide device includes a number of pairs of right and left side plates connected to each other. Cable accommodating space extension arms are bridged over the flexional inner circumferential sides of at least one pair of side plates. D-shaped pin hinge shafts in the hinge ends of the arms are detachably interengaged with a groove in one of the side plates and thus permits the arm to pivot with respect to the side plate. Hinge end side locking pawl pieces of the arms are interlocked to the side plates.

Abstract: The present invention provides a cable protection and guide device adapted for easy, sure storage and arrangement of cables in a cable storage space. The cable protection and guide device 100 is detachably provided with a partition shelf board member 120 for dividing a cable storage space R for storing, arranging, guiding and protecting cables C into a bending inner circumferential side and a bending outer circumferential side, and a pair of partition wall board members 130 for laterally dividing the space. The partition shelf board member 120 includes a pair of right and left engagement adaptor parts 121, 121 to be engaged with a pair of right and left partition wall board members 130, 130, respectively, and each of the partition wall board members 130 includes a pair of positioning ratchet teeth 131, 131 cut in slit opposed faces 131a, 131a.

Abstract: In a roller chain in which a plurality of rolling bodies is disposed between a roller and a bushing, between a bushing and a pin, or between a roller and a pin, the rolling bodies include at least one carbon-impregnated ceramic rolling body, or at least one carbon-coated steel rolling body. Preferably, the carbon-impregnated or carbon-coated rolling bodies are disposed in an alternating configuration with steel rolling bodies.

Abstract: A speed-increasing and accumulating conveyor chain includes a large-diameter mounting roller and small-diameter traveling rollers that are loosely fitted concentrically around a connecting pin through over an oil-impregnated sintered oil bushing concentrically. A lubricating oil is gradually discharged from the oil-impregnated sintered bushing, so that the chain can travel with a small chain-driving force as a whole while stably maintaining low friction coefficients at the loosely fitted portions between the connecting pin, the bushing, the mounting roller and the traveling rollers. The chain can, therefore, perform the speed-increasing function and the accumulating function by means of the mounting roller and the traveling rollers.

Abstract: The optical information recording and reproducing apparatus of the present invention comprises a detecting device detecting that an optical disc-like recording medium, having a spiral track, has made one rotation. A track jump circuit moves the position of a light beam, radiated on one segment of the spiral track of the optical disc-like recording medium, to an objective track segment. A track jump correcting circuit corrects the position of the light beam by the number of tracks which is equal to the number of one-rotation detecting signals obtained from the detecting device during the movement by the track jump circuit. A kick back circuit holds the light beam to always be radiated on the objective track segment.
