摘要： An air blower/vacuum (1) includes a nozzle (3), a fan (8), and a main body (2). The main body (2) is formed with a vacuum pathway (15) and a blower pathway (16), located upstream and downstream, respectively, from the fan (8) with respect to the flow of air. The main body (2) is also formed with an attachment hole (18) in fluid communication with both the vacuum pathway (15) and the blower pathway (16). The attachment hole (18) supports the nozzle (3) rotatable between a vacuum mode orientation and a blower mode orientation. In the vacuum mode orientation, the pathway (33) of the nozzle (3) is in fluid communication with the vacuum pathway (15). In the blower mode orientation, the pathway (33) of the nozzle (3) is in fluid communication with the blower pathway (16).

摘要： A blower nozzle (30) and a vacuum nozzle (40) extending in parallel with each other are connected to a main body (10) housing therein a fan (19) and a motor (20). The main body (10) is provided with a dust bag (50). In a vacuum mode, air is directly sucked from the vacuum nozzle and is introduced into the dust bag by the rotation of the fan. In a blower mode, the air similarly sucked from the vacuum nozzle is directed toward the blower nozzle.

摘要： A closed deck type cylinder block providing an optimum area ratio of opening at a top deck side, and a method for producing such cylinder block having the reduced area ratio of the opening at a reduced energy cost and with reduced labor, yet exhibiting smooth discharge of waste sand converted from a water jacket core through the opening in spite of the reduced area ratio of the opening. The cylinder block (10) is formed with a plurality of cylinders (10d) juxtaposedly arranged to each other and a water jacket portion (10a) surrounding the cylinders (10d). An upper end of the water jacket portion is open at a top deck and is partly covered with bridge portions (10c). The opening (10b) has an area ratio of from 10 to 30% of a projection area (10a) of the water jacket portion at the top deck surface.

摘要： A cleaning system and method for cleaning an interior of a liquid passage (10) formed in a metal mold (1) or other pipeline system so as to remove scales, slime or rust deposited on or generated in the interior of the passage. A cleaning liquid tank (2) is connected to an inlet (10a) of the liquid passage through a cleaning liquid supply passage (8), and outlet of the liquid passage is connected to the tank by way of a cleaning liquid discharge passage (10b) for recirculating the liquid. A diaphragm type pump (3) is provided at the cleaning liquid discharge passage so as to introduce the cleaning liquid into the liquid passage under negative pressure. The diaphragm type pump generates liquid flow pulsation to impart a physical impact on the deposited material. Compressed air can be applied into the cleaning liquid flowing at the cleaning liquid supply passage.

摘要： A grinding machine in which both a belt sander and a spindle sander may be selectively used, a base is mounted on a holder member when the belt sander is used and the base is removed away from the holder member when the spindle sander is used. A fastening pin rotatably penetrates the base. An operational section is provided for rotating the fastening pin. An eccentric portion having a center at an eccentric position relative to a rotational center of the operational section and having a taper shape is formed in the fastening pin on a side of the holder member. A slanting hole into which the eccentric portion of the fastening pin may be inserted is formed in the holder member. An angle of the slanting hole is smaller than a taper angle of the eccentric portion of the fastening pin.

摘要： A horizontal type casting machine capable of facilitating installation of a water jacket core (122) and providing sufficient fluidity of the molten metal without generation of gas defect in casting a water-cooled type cylinder block. In the horizontal type casting machine, a cavity for the cylinder block is oriented vertically in which a cylinder bore portion of the cylinder block is positioned up and a crank chamber is positioned down. The cavity is defined by a stationary die (103), a movable die (104) and movable cores. A movable slide core is provided movable relative to the movable die. When the movable slide core is moved to its retracted position, large working space is provided for installing the water jacket core (122) at a given position. By the retracted movement of the movable slide core, large working space can be provided, thereby facilitating installation of the water jacket core (122). Further, since the water jacket core (122) is set in its suspended fashion, easy positioning of the water jacket core results.

摘要： An automatic molten metal supplying device capable of supplying the molten metal within a short period of time with maintaining accuracy in supplying amount and without any dripping of the molten metal from a ladle and without any temperature decrease of the molten metal in the ladle during its transferring state even if the transferred molten metal has a small volume. A molten metal intake/discharge port is formed at a bottom portion of a ladle, and atmosphere communication/blockage unit is provided which selectively communicates an internal space of the ladle with an atmosphere. After the molten metal is introduced into the ladle through the intake/discharge port, the space is shut off from the atmosphere. A cross-sectional area of the intake/discharge port is in a range of from 20 to 80 mm 2 . Lower limit of the cross-sectional area of the intake/discharge port is still sufficient to allow the molten metal to be flowed into the ladle, and upper limit thereof is sufficient to prevent the molten metal in the ladle from being dripped therefrom. Thus, small amount of the molten metal can rapidly and accurately casted.
