Abstract: A work machine according to the present invention optimally collects work chips, such as dust, produced during work. In a circular saw 10, a sawdust discharge port 27H and a cover opening 27J are formed in an inner cover 27, and a dust collecting chamber inlet 62L1 and a dust collecting chamber outlet 62L2 are formed in a dust collecting case 60. Furthermore, at least a portion of the dust collecting chamber inlet 62L1 and at least a portion of the dust collecting chamber outlet 62L2 are arranged at the same position in the vertical direction.

Abstract: A dust collection device 40 comprises: an intake pipe 53 connected to a suction unit 52; a cyclone unit 60 that swirls air flowing out from the intake pipe 53 and centrifuges dust; and a filter unit 70 that accommodates a filter 72. The filter unit 70 has an outlet 74 connected to the cyclone unit 60 and discharging the air having passed through the filter 72. Therefore, the air and dust near a tip tool T can be separated by the cyclone unit 60. Furthermore, even when the dust remains, the remaining dust can be removed by the filter 72. Furthermore, the intake pipe 53 and the cyclone unit 60 are arranged at positions where the intake pipe 53 and the cyclone unit 60 overlap in a front-rear direction, and the filter unit 70 is disposed behind the cyclone unit 60.

Abstract: Provided is a vacuum cleaner comprising: a main body housing 10 which houses a motor and a fan and which has an intake by which an airflow created by the fan enters inside; and a dust collection unit which is attachable to and detachable from the main body housing 10 so as to cover the intake. The main body housing 10 has an attachment-receiving part 30 with a common shape such that a cyclonic dust collection unit 50 which separates fine particles using a cyclonic air flow and a dust collection unit which carries out dust collection by filtration without using centrifugal force can be interchangeably attached to and detached from the main body housing as the dust collection unit.

Abstract: As a result of the rotation of a fan (65) driven by a motor (40) inside a housing (2), dust-laden air that has been sucked in from a nozzle (92) passes through a filter device (95), flows as in (C1, C2), and is discharged from a discharge port (30) to the outside of the housing (2). Viewed in the direction of the axis (A1) of the motor (40): an air intake port (10) is located in front of the motor (40); a battery pack (100) is located behind the motor (40); and a handle (4) is located behind the motor (40). The air exhaust port (30) is located between the handle (4) and the battery pack (100) and is provided behind the center position of the battery pack (100) in the axis (A1) direction.

Abstract: The present invention relates to a process for improving mineral absorption in a subject comprising administering to the subject a mineral-absorption promoter comprising indigestible dextrin or a derivative thereof as an effective component together with a mineral-containing diet or supplement.

Abstract: The present invention relates to a mineral-absorption promoter comprising hardly digestible dextrin or a derivative thereof, as well as food and feed containing the same. The mineral-absorption promoter of the invention can easily be applied to food, has resistance to digestive enzymes secreted by mammals and a function of promoting the absorption of minerals through intestinal or digestive tracts.
