Abstract: A portable gun-type adhesive discharger operable independent of an external power source. The adhesive discharger includes a main case body for supporting a rigid adhesive stick extending in a longitudinal direction, a hand grip portion for manually holding the main case body, a heating unit disposed in the main case body for melting the adhesive stick, a nozzle portion connected to a front end of the main case body for discharging melted adhesive stick, and a trigger portion disposed at the hand grip portion and connected to the adhesive stick for feeding the adhesive stick toward the nozzle portion. The main case body and the hand grip portion provide an interior space in combination. A gas supply unit having a gas reservoir is provided in the interior space, and catalytically combustible gas is filled in the reservoir. The heating unit includes a catalytic combustion unit disposed in the interior at a position adjacent the adhesive stick.

Abstract: An off-set printing machine for printing a continuous web includes a first pair of gears 12c, 14b in mesh with each other, one gear being fixedly mounted coaxially on one of blanket and impression cylinders 12, 14 for rotation therewith while the other gear is rotatably mounted coaxially on the other of the cylinders and is releasably fixable thereto for rotation therewith. There are provided a second pair of gears 12b, 10b in mesh with each other, one of the second pair of gear being fixedly mounted coaxially on one of the blanket and plate cylinders 12, 10 for rotation therewith while the other of the second pair of gears is rotatably mounted coaxially on the other of the blanket and plate cylinders and is releasably fixable thereto for rotation therewith.

Abstract: A mechanism for continuously supplying a dampening medium in an offset printing machine is disclosed. The mechanism includes a dampening medium applicator roller in rotational contact with a master plate on a master cylinder, a dampening medium transfer roller in rotational contact with the applicator roller, a dampening medium distributor roller in rotational contact with the transfer roller, a dipping roller in rotational contact with the distributor roller, and a metering roller in contact with the dipping roller. The applicator roller and the transfer roller have their outer peripheral surfaces provided with elastic material layers.

Abstract: In a double bearing fishing reel, one end portion of the spool shaft rotatably supported between the right and left side frames of the reel body in such a manner as to be rotated with the handle is extended through a bearing hole formed in a male-threaded protrusion which is provided on one of the side frames, and a protrusion is formed on the cylindrical wall of a brake adjusting screw member which is threadably engaged with the male-threaded protrusion to abut against the spool shaft in the axial direction, while a retaining member is provided on the one side frame in such a manner that the protrusion and the retaining member are engageable with each other in the axial direction, whereby the brake adjusting screw member is restrained form loosening or coming off.

Abstract: A joint planer has a chute for guiding chips resulting from a planing operation to a dust collector guide. The chute is attached to a vertically-movable table near its work surface and extends to the upper edge of the dust collector guide, which is below the planer cutting barrel. The lower end of the chute slides up and down against the edge of the dust collector guide with movement of the vertical table, thereby maintaining a closed path from the surface to the dust collector guide.

Abstract: An aluminum part joint structure including at least two casted joint pieces to be assembled together, each of the pieces being formed with joint surfaces. Adhesive agent layer is provided between the joint surfaces. The adhesive agent comprises 45 to 54 wt % of epoxy resin, 30 to 40 wt % of aluminum particles each having diameter of 0.1 to 0.2 mm, and 4 to 6 wt % of guanidine derivative.

Abstract: In a multi-color printing machine, any positional error of a image is corrected by a longitudinal image displacement correcting mechanism and/or a diagonal image adjusting mechanism. In the former mechanism, the phase of a paper-feed cylinder relative to an impression cylinder is changed by utilizing the principle of a helical gear. In the latter mechanism, the paper-feed cylinder is tilted or twisted relative to the impression cylinder.

Abstract: A spinning reel having a reverse rotation preventing mechanism for selectively preventing the reverse rotation of the rotor of the reel in which the amount of protrusion of an operating lever for setting the rotation preventing state is reduced. A rocker lever pivotably mounted to the reel body has only one actuating portion extending beyond the surface of the reel body when in either operative position, namely, the rotation locked or unlocked position. A forward arm of the rocker lever is pivotably joined to a locking lever, the forward end of which is engageable with a locking gear fixed to the shaft of the rotor. If desired, a locking pawl can be interposed between the forward end of the locking lever and the locking gear.

Abstract: A fishing spinning reel having reverse-rotation-preventing mechanism comprising a plastic spring press-fitted on a master gear shaft and having a protrusion extending radially therefrom to engage a recess formed in a reverse-rotation-preventing pawl pivotally mounted on the reel body, so that the pawl engages a ratchet formed on a rotor-supporting cylindrical shaft when the handle is turned in the reverse direction and disengages from the ratchet when the handle is turned in the forward direction.

Abstract: A method for forming an as-cast hole by using a core involves forming an undercut and casting by using a core die which is slidable at an angle with respect to mold closing and opening directions. At the same time, an as-cast hole with an axial direction different from the slide direction of the core die is formed. To form the as-cast hole, a floating core is slidably disposed in the core die for movement in the axial direction of the as-cast hole. An apparatus for practicing the method includes a stationary die, a movable die and the core die containing the slidable floating core.
