A stop system for an engine of a work machine includes an engine stop control unit and an engine stop control suspension unit. The engine stop control unit, in a case in which there is a stop instruction that instructs to stop the engine of the work machine, performs delayed stop control to delay the stop of the engine until a predetermined condition is established, and then stops the engine. The engine stop control suspension unit, in a case in which there is a cancellation instruction to cancel the stop instruction, suspends the delayed stop control when work equipment of the work machine is in a locked state, and continues to perform the delayed stop control when the work equipment is in an unlocked state.

An ultrasonic sealing apparatus for paper packages achieves more stable ultrasonic sealing by cooling the horn during ultrasonic sealing which would otherwise be unstable due to heat imparted to a horn by continuous sealing. An end portion of a horn of a casing that includes the horn and a converter, or the horn, a booster and the converter is cooled by supplying air to a frame portion exposed toward an anvil side.

A display system of a work machine having a working unit with a bucket attached thereto, includes a generation unit generating drawing information to draw an image of the bucket viewed from a side using information of shape and size of the bucket, and a display unit displaying the image of the bucket viewed from the side and an image indicating a cross-section of landform based on the drawing information. The information of the shape and size includes, in the side view of the bucket, a distance between a blade edge of the bucket and a bucket pin attaching the bucket to the working unit, a distance between the bucket pin and a predetermined position at an outer side of the bucket, and an angle formed by a straight line connecting the bucket pin and the blade edge and a straight line connecting the bucket pin and the predetermined position.
