  • Publication number: 20240293889
    Abstract: A friction stir tool control method is a control method for controlling an operation of a friction stir tool by supplying a necessary drive electric current to a drive source of the tool. The control method includes obtaining a pressurizing force change ratio by comparing a set pressurizing force predefined as a pressurizing force at plunging of the tool into a workpiece with an actual pressurizing force occurring at actual plunging of the tool into the workpiece by supplying a drive electric current for generating the set pressurizing force to the drive source. The drive electric current is regulated in accordance with the pressurizing force change ratio so that the actual pressurizing force comes to the set pressurizing force, and the drive source is driven with the regulated drive electric current.

  • Patent number: 10434133
    Abstract: An oligopeptide having a good anti-inflammation effect on microglia has been found, and based on this finding, a composition to be used for suppressing the inflammation of microglia is provided. Inflammation suppression action of a dipeptide has been comprehensively analyzed using the proinflammatory cytokine production of microglia as an indicator. As a result, it has been revealed that an oligopeptide including the sequence LH, DV or MH has a good inflammation suppression effect. The composition containing any of these oligopeptides can provide a composition having the effect of suppressing the excessive inflammatory action of microglia.

  • Publication number: 20160178036
    Abstract: A hydraulic pressing unit for pressing an input disc in an axial direction includes a first hydraulic pressure chamber and a second hydraulic pressure chamber, a primary piston facing the first hydraulic pressure chamber and a secondary piston facing the second hydraulic pressure chamber, and oil holes configured to supply oil into the first hydraulic pressure chamber are formed in an input shaft, while oil paths configured to supply oil into the second hydraulic pressure chamber are formed in the secondary piston. Consequently, a separate oil hole configured to supply oil into the second hydraulic pressure chamber is not formed in the input shaft. Thus, it is possible to mitigate the cost and labor hours involved in fabrication of the input shaft. Two oil holes spaced apart from each other in an axial direction do not exist in the input shaft.

  • Patent number: 8998498
    Abstract: A tapered roller bearing improves durability during a state of insufficient lubrication by sufficiently lengthening the time until rotation becomes impossible due to seizure. Oil retaining concave sections, recessed outward in the radial direction, are formed in portions on the inner circumferential surface of a large-diameter rim section of the retainer whose phase in the circumferential direction coincides with the pockets. A portion of the bottom surface of each of the oil retaining concave sections, open to the inside surface of the pocket, face a concave section formed in an end surface on the large-diameter side of tapered roller that is held inside the pocket. When lubrication becomes insufficient, oil remaining in the concave sections is effectively used for lubricating areas of sliding contact between the end surfaces on the large-diameter side and the inside surface in the axial direction of a large-diameter side flange section.
