Abstract: A liquid ejecting head that includes a fluid channel formation substrate and pressure generation units. The fluid channel formation substrate is made of a silicon single crystal substrate having a crystal face orientation of. The fluid channel formation substrate has a plurality of separate flow channels that include at least pressure generation chambers demarcated by partition walls, each of the pressure generation chambers being in communication with a nozzle opening that ejects liquid drops. The fluid channel formation substrate further has a communication portion that is in communication with each of the separate flow channels. The pressure generation units are provided so as to correspond to the pressure generation chambers and generate a pressure change in the pressure generation chambers so as to cause ejection of liquid drops.

Abstract: A liquid ejection head including: a flow-channel forming substrate having a pressure generating chamber which communicates with a liquid supply channel which communicates with one end of the pressure generating chamber in terms of a first direction so as to have a first length for supplying liquid to the pressure generating chamber; and a pressure generating unit that causes the change in pressure in the pressure generating chamber, wherein the liquid supply channel is formed by narrowing the width of the pressure generating chamber in a second direction substantially perpendicular to the first direction so as to have a second length shorter than the first length, a stepped surface is formed between the side surface of the pressure generating chamber in the second direction and the side surface of the liquid supply channel in the second direction, and wherein a bridge is provided at a corner defined by the stepped surface, the side surface of the pressure generating chamber in the second direction on the step

Abstract: A hemming machine is provided with a frame, a hemming tool support structure and a swinging drive structure. The hemming tool support structure is rotatably coupled to the frame to rotate about a center rotation axis. The hemming tool support structure includes a hemming tool disposed at a first location such that the hemming tool moves towards and away from an edge part of a workpiece that is supported on a die upon rotation of the hemming tool support structure. The swinging drive structure transmits a rotational driving force to the hemming tool support structure via a releasable connection located on a side of the center rotation axis that is opposite of the hemming tool. The releasable connection is configured to release the swinging drive structure to allow further rotational movement of the hemming tool away from the die.

Abstract: A hand transport section holds and transports a workplace grip hand for gripping and positioning a workpiece. The hand transport section mounts the workpiece grip hand on a hand mount so as to set the workpiece on a lower die. The hand transport section releases the workpiece grip hand and retracts. The hemming device hems the workpiece with the lower die and an upper die located above the lower die.

Abstract: A C-type frame is movable in a direction in which the C-type frame is adjacent to and away from a workpiece having an outer panel and an inner panel assembled with each other. After the C-type frame is advanced and a pre-hemming punch is advanced by a swing cylinder provided at the C-type frame, a hemming die is raised by a lifter hydraulic cylinder provided on a lower portion of the C-type frame and a flange of the outer panel is provisionally hemmed. Then, after retreat of the pre-hemming punch following lowering of the hemming die, the hemming die is raised again and final hemming is conducted between the hemming die and the hemming punch.

Abstract: A C-shaped frame is movable in a direction in which the C-shaped frame is adjacent to and away from a workpiece having an outer panel and an inner panel assembled with each other. After the C-shaped frame is advanced and a pre-hemming punch is advanced by a swing cylinder provided at the C-shaped frame, a hemming die is raised by a lifter hydraulic cylinder provided on a lower portion of the C-shaped frame and a flange of the outer panel is provisionally hemmed. Then, after retreat of the pre-hemming punch following lowering of the hemming die, the hemming die is raised again and a final hemming is conducted between the hemming die and the hemming punch.

Abstract: A rolling bearing is described, which comprises an inner ring fitted onto a shaft, an outer ring fitted in the housing, a plurality of rolling elements provided interposed between the inner ring and the outer ring and a lubricant packed thereinside and which is mounted between the shaft and the housing, wherein a rust preventive film comprising an oil-repellent material is formed on at least the outer surface of the outer ring and the inner surface of the inner ring, and a bearing apparatus is also described.
