20120251346 | Air Compressor - An air compressor includes a motor, an air compression mechanism driven by the motor, a rotation shaft rotatable integrally with a rotor of the motor, a fan rotatable integrally with the rotation shaft, a plurality of air tanks for reserving compressed air generated by the air compression mechanism, and a control unit for controlling the motor. The plurality of air tanks are juxtaposed with each other and arrayed in an array direction. The plurality of air tanks includes an endmost air tank and an adjacent air tank adjacent to the endmost air tank. The control unit is disposed adjacent to and opposite to the adjacent air tank relative to the endmost air tank. The control unit is disposed adjacent to and in confrontation with an outer circumference of the fan. | 10-04-2012 |

20090031875 | Miter Saw - A miter saw has a base unit, a cutting unit, and a supporting unit. The base unit supports a workpiece. The cutting unit has a rotary cutting blade having two side faces, a motor for driving the rotary cutting blade, and a housing having a blade cover for covering a part of the cutting blade and a motor housing provided to the blade cover on one side face of the rotary cutting blade for accommodating the motor. The supporting unit is supported to the base unit for pivotably supporting the cutting unit. The supporting unit is configured to move the cutting unit toward and away from the base unit in a first direction. The support unit has a guide unit supported to the base unit, and a sliding unit having a pivot shaft pivotably supporting the cutting unit. The guide unit extends parallel to a second direction and having a front end. The sliding unit is guided by the guide unit to move between a front position and a rear position in the second direction. The pivot shaft extends in a third direction perpendicular to the first and second directions. The motor housing has a proximal end to the rotary cutting blade and a distal end in the third direction. At least one part of the guide unit is positioned on the one side face and between the cutting blade and the distal end in the third direction. When the sliding unit is positioned at the rear position, a first distance between the pivot shaft and a closest point of the motor housing to the pivot shaft in a plane extending in the first direction and containing the guide unit is longer than a second distance between the pivot shaft and the front end of the guide unit in the plane. | 02-05-2009 |
20110283856 | CUTTER WITH LASER GENERATOR THAT IRRADIATES CUTTING POSITION ON WORKPIECE TO FACILITATE ALIGNMENT OF BLADE WITH CUTTING POSITION - A cutter including a base, a holder, a cutter blade portion, and a laser generator. The holder is supported on the base portion in an upright posture. The cutter blade portion supports a moving blade. The cutter blade portion is supported on the holder movable between an upper position and a lower position. The cutter blade portion is moved into the lower position to cut a workpiece supported on the base using the moving blade. The laser generator is attached to the holder or the cutter blade portion in an orientation to direct at least a portion of the laser light onto a position on the workpiece that is directly beneath the cutter blade portion when the cutter blade portion is in the upper position. Alternatively, a holder has a shaft support portion, and a slide shaft is axially slidably supported by the shaft support portion. A front end of the slide shaft has a hinge holder which pivotally supports the cutting blade portion. A laser generator is fixed to a front side of the hinge holder. | 11-24-2011 |
