20080305908 | Joint driving apparatus for robot - A joint driving apparatus for a robot comprises an oscillating internally meshing reduction mechanism, a center shaft member, a ring portion, and an oil seal disposed between the ring portion and the center shaft member. The oscillating internally meshing reduction mechanism is fixed to a first member and rotates the second member relatively with respect to the first member. An output member is arranged at the side of an external gear in an axial direction so as to output a relative rotation of an internal gear with the external gear. The center shaft member is fixed to the output member, and has a shaft portion extending up to the side opposite to the external gear in the axial direction of the output member. The ring portion is integrally formed with the first member and faces to the shaft portion of the center shaft member. The oil seal is disposed between the ring portion and the shaft portion. | 12-11-2008 |

20150029265 | LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS - A liquid ejection head includes an electrical wiring substrate and a printing element substrate, wherein the position variation of the printing element substrate due to curing of a sealing agent is eliminated. Specifically, a gap between two support members is covered with the electrical wiring substrate so as to be able to prevent a first sealing agent from flowing into this gap. As a result, even in the case where the size of the gap varies due to the variation in the dimensional accuracy and/or the variation in the assembly accuracy, the first sealing agent will not enter this gap, and therefore the shape thereof can be made substantially uniform regardless of the positions. This results in a substantially uniform stress in curing and contracting of the first sealing agent, and the variation in the mounting position of the printing element substrate can be suppressed. | 01-29-2015 |
20150085018 | LIQUID EJECTION HEAD - A liquid ejection head includes a plurality of ejection members, each having an ejection port for ejecting liquid and a liquid chamber for supplying liquid to the ejection port, a base substrate carrying the plurality of ejection members arranged thereon, the base substrate being provided with a common flow channel for supplying liquid to the plurality of liquid chambers, and a plurality of branch ports each allowing the common flow channel to communicate with the plurality of liquid chambers. Each of the branch ports is provided with a notch portion at an upstream side thereof as viewed in the flow direction of liquid flowing through the common flow channel. | 03-26-2015 |
