Abstract: A damper valve includes first and second chambers separated by a partition wall, hydraulic oil flowing from the first chamber to the second chamber via a supply path, and returning to the first chamber from the second chamber via a return path. A valve plate that is elastically deformable is urged toward a valve seat formed in the return path. The valve plate produces an elasticity restoring force so as to establish a balance between an urging force provided by an urging member and a reaction force provided by the valve plate, and is in line-contact with the valve seat when keeping the balance. The valve seat or the valve plate is formed into a conical tapered shape centered around the predetermined axis so that when the valve plate is abutted against the valve seat, an annular oil chamber is formed between the valve seat and the valve plate.

Abstract: A damper valve comprises a casing having a first chamber and a second chamber that are separated from each other by a partition wall, a supply path for supplying to the second chamber hydraulic oil in the first chamber through a check valve, and a return path for returning to the first chamber hydraulic oil in the second chamber. A valve plate that is elastically deformable is urged toward a valve seat provided on the partition wall. The supply path comprises a penetration path that penetrates the partition wall along a predetermined axis. The return path comprises a communication path that communicates the first chamber and the second chamber with each other by penetrating the partition wall. The communication path has an opening formed on the valve seat. Either of the valve seat or the valve plate is formed into a conical tapered shape centered around the predetermined axis.

Abstract: A silent chain comprises a link assembly including at least two inner link plates each having a pair of teeth and bushing holes and connected and fixed to each other with a pair of bushings press-fit into said respective bushing holes, an intermediate link plate including a pair of teeth and bushing holes, and a guide plate including a pair of pin holes. The members are combined and articulably connected to by other with connecting pins. A row of link assemblies is disposed in the center with respect to the width direction of the chain and extends along the longitudinal direction of the chain. The intermediate link plates are disposed on both sides of the link assembly and guide plates are disposed on outer sides of each of the intermediate link plates. Each bushing in the link assembly disposed between said intermediate link plates has a length substantially equal to the spacing space between the intermediate link plates.

Abstract: A conveyor apparatus includes first and second groups of fins which are spaced along the conveying direction to provide spaces sufficient to hold packs therein. The fins in each group are divided into first and second sets. The first and second fin groups are mounted to first and second conveyor chain pairs, respectively, and moved through pack loading and unloading stations. Stepping motors drive the first and second chain pairs independently. A controller causes a fin set after being loaded or unloaded to be forwarded to the unloading or loading station at a speed higher than the speed at which the fin sets move through the loading station.
