Abstract: A variable cutting-angle circular saw device includes a base; a rotary table 2 rotatably disposed in the central portion of the base; a bracket liftably attached to a hinge; a motor, a speed reducer, a circular saw, an outer cover, and a safety cover, all being fixed to the bracket; a fence fixed in a rearward position of the base; a clamp fixed at left- and right-hand positions of the device so as to allow a workpiece to be clamped for cutting the workpiece. A sawdust-guiding frame piece is suspended from a lower end of a rear portion of the cover so as to smoothly block a gap between the lower end of the rear portion of the outer cover and an upper surface of a curved portion in the central portion of the fence, guiding the sawdust blowing up via the blow-up port, to the inner side of the rear end of the outer cover. A sawdust accommodating chamber below the rotary table is closed at the bottom and has a substantially arcuate bag-like shape, and communication with the cover via a port at the rear thereof.

Abstract: A clutch mechanism for a fishing reel having a spool and a spool shaft supported at both ends by a pair of side plates. a handle for rotating the spool and spool shaft is engaged through a drive gear to a pinion gear. The pinion gear is slideably mounted on the spool shaft and the device includes clutch means on the spool shaft to engage and disengage the pinion gear with the spool shaft by moving the pinion gear axially on the spool shaft. A clutch cam moves the pinion gear axially and an operating lever is linked to the clutch cam for disengaging the pinion gear from the spool shaft. Rotation of the handle in a first direction causes the pinion gear to engage the spool shaft and an operating lever is rotatably supported on a shaft extending between the side plates of the fishing reel.

Abstract: An ink removing system for an offset printing machine utilizes a pair of cleaning tank mounting guides secured to left and right side frame walls of the printing machine having recesses therein facing each other. A cleaning tank is provided with a pair of axially detachable mounting pins projecting symmetrically longitudinally of the cleaning top to opposite sides thereof and engaged within the recesses for rotatably mounting the tank. A cam shaft rotatably supported by the vertical frame walls carries cams operatively engaging bracket mounted adjusting screws functioning as cam followers on the cleaning tank and engaging the periphery of the cams such that rotation of the cam shaft rotates a vertically projecting cleaning blade fixed to the cleaning tank and to edge contact with the periphery of the ink roller for cleaning of the same. Rotation of the cam shaft is limited to high and low can positions corresponding to blade contact with the ink roller and displacement laterally to the side thereof.
