摘要： A cutting machine which comprises a circular saw blade, a casing which covers the saw blade and supports a saw blade spindle, a base plate which supports the casing in a pivotable manner, a lower guide which covers a bottom section of the saw blade, a pivoting connection member which pivots the lower guide, and a connecting-member structure which is either locked, in which case it prevents vertical pivoting of the casing, or is released from the locked position, in which case it permits vertical pivoting of the casing by a change in the relative positions of the connecting-member structure. Given this construction, accidental release of the saw blade is prevented.

摘要： There is provided a sheet feeder for a sheet-fed press which allows an optimum separation state of printing sheets 27 to be established readily and certainly. Air is jetted out from an injection nozzle 6 toward the upper part of a bundle 2 of printing sheets to thereby float up printing sheets 27. A top printing sheet 27 thus floated is absorbed by an absorption foot 8 and conveyed to a printing process. The number of floating printing sheets 27 is detected using photoelectric sensors 21 and 22, and in order to establish the optimum separation state, is adjusted by varying the injection air quantity from the injection nozzle 6 or by moving the paper pressure bar 4 in directions of arrows 93 and 94. Further, by equalizing outputs G1 and G2 from detection areas M1 and M2, it is possible to place the top printing sheet 27 in parallel with the absorption surface 8Q of the absorption foot 8 and realize secure absorption. A fuzzy inference system may be used for adjustment.

摘要： A number printing unit for an offset printing machine in which blocks are fixed to a numbering unit mounting holder provided rotatably on an operation side frame. Coupling retainer blocks are inserted into groups formed in the blocks. The coupling retainer blocks are mounted on the numbering unit mounting holder by screws, washers and bolts. A gear is rotatably mounted on the numbering unit mounting holder through a bearing. A coupling ring is fixed to the gear by screw. Abutment portions of the coupling retainer blocks are brought into contact with the coupling ring.

摘要： A printing machine in which a perforation pressure drum is disposed downstream of a paper feeding section, and a longitudinal perforation blade and a lateral perforation blade may be brought into contact with the perforation drum. A delivery drum is in contact with the perforation drum, and a numbering pressure drum is in contact with the delivery drum. A numbering box may be brought into contact with the numbering pressure drum. With such an arrangement, it is possible to enhance printing position precision and operational property.

摘要： 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. An ignition unit is provided in the interior for igniting the combustible substance fed to the catalytic combustion unit from the gas supply unit.

摘要： The screw driver has a drive shaft (16) which is rotated by a motor (8) in the housing (7). A driven shaft (11) moves axially towards and away from the drive shaft (16) and has an extension (25) at its front end. A coupling (30) is arranged between the drive shaft (16) and the driven shaft (11). A central bore is formed along the middle axis of the drive shaft (16). An actuator rod (33) passes through the bore. The front end of this rod (33) is connected to the driven shaft (11). The back end projects back from the drive shaft (16). The auxiliary switch (39) is arranged in an electric circuit comprising the motor and a battery in series with the main switch. The aux. switch (39) is switched on when it is pressed down by the actuator rod (33) which moves backwards when the screw is fastened. The rod (33) moves coaxially to the middle axis of the drive shaft. ADVANTAGE - Reduced energy loss and less operating noise.
